Description

Technical Field

[0001] This invention relates to the field of food processing and production process control technology, and in particular to a collaborative production control method and system for the batch low-temperature quick-freezing and shelling process of quail eggs. Background Technology

[0002] In the field of food processing and production process control technology, peeling after low-temperature quick-freezing is a crucial step in improving peeling efficiency and yield. Existing production processes typically consist of multiple independent stations connected in series, including washing pretreatment, low-temperature quick-freezing, thawing and shell cracking, and peeling and separation. The operating cycle time and process parameters between each station are mostly based on preset values ​​or roughly adjusted using manual experience.

[0003] The existing methods have the following main shortcomings. First, the control of each station is independent, lacking a collaborative judgment mechanism for the state of the front-end raw materials (such as eggshell moisture content, degree of adhesion residue, and surface integrity) and the load of the back-end equipment (such as buffer occupancy at each station and equipment operating load). When the state of the front-end raw materials changes or congestion occurs at the back-end stations, the fixed pretreatment parameters can easily lead to incomplete cleaning, eggshell damage, or blockage of the entire line. Second, when abnormal egg flows occur (such as stuck shells, uncleaned shells, or insufficient shell cracking), the existing system usually only performs simple rejection or uniform recirculation, lacking precise classification and differentiated processing paths for different types of abnormalities. This results in unstable reprocessing effects of abnormal egg flows, affecting the overall shell cleanliness rate. Third, the existing control methods are mostly unidirectional open-loop operations, unable to automatically correct the process parameters of subsequent batches based on the production results of historical batches (such as shell cleanliness rate, breakage rate, and blockage location). After long-term operation, the system is unlikely to maintain stable shell peeling quality. Finally, due to the lack of cross-workstation buffer queue scheduling capability, when the load of a certain workstation fluctuates, it is easy to cause the cycle time of the workstations before and after the workstations to be misaligned, resulting in a decrease in the overall line throughput efficiency or even shutdown and waiting.

[0004] The aforementioned problems make it difficult for existing technologies to achieve continuous, stable, and adaptive collaborative control of the low-temperature quick-freezing peeling process in batch production scenarios where raw material conditions vary and equipment loads change dynamically. Summary of the Invention

[0005] To address the above problems, this invention provides a collaborative production control method and system for the batch quail egg low-temperature quick-freezing and shelling process. This system is used to solve the problem of how to achieve whole-line collaborative control in the quail egg low-temperature quick-freezing and shelling process based on batch input set and clean egg flow and abnormal egg flow, through linkage condition mapping and cycle correction of raw material side status and line side load, as well as cycle construction, buffer queue scheduling, multi-parameter linkage correction and differentiated backflow reprocessing.

[0006] To address the aforementioned technical problems, this invention provides a collaborative production control method for the batch low-temperature quick-freezing and shelling process of quail eggs, comprising:

[0007] S100, based on the collaboration of the workstation for incoming line acquisition, status aggregation and batch input set generation, performs batch identification, equipment status acquisition and time alignment, field mapping and unified encoding to obtain the batch input set;

[0008] S200. Based on the batch input set, perform linkage condition mapping and cycle correction between raw material side status and line side load to obtain quick-freezing preparation instructions.

[0009] S300: Based on the quick-freezing preparation instructions, perform layered storage, freezing and maintenance and outbound rhythm matching to obtain egg products in the target frozen and bulging state;

[0010] S400. Based on the target frozen and swollen egg product, perform warming buffering and directional shell cracking treatment to obtain a peelable egg stream.

[0011] S500: Based on the peelable egg flow, perform flexible shell removal, broken shell removal, integrity detection and abnormal classification to obtain clean shell egg flow and abnormal egg flow;

[0012] S600. Based on the clean egg flow and abnormal egg flow, perform cycle time construction, buffer queue scheduling, multi-parameter linkage correction and differentiated backflow reprocessing to obtain the overall line collaborative control result.

[0013] Furthermore, the collaborative process of the workstation based on incoming line acquisition, status aggregation, and batch input set generation includes:

[0014] The in-line data collection station is located at the beginning of the conveying section to perform batch identification and arrival confirmation on the quail eggs entering the production line.

[0015] The status aggregation station is connected to the low-temperature quick-freezing unit, the rewarming and shell-cracking unit, the shell-peeling and separation unit, the buffer queue, and the abnormal egg flow channel, and receives the current equipment operating status.

[0016] The batch input set generation station performs time alignment, field mapping, and unified encoding on the aforementioned collection results.

[0017] Furthermore, the process of batch identification, device status acquisition and time alignment, field mapping, and unified encoding includes:

[0018] The batch identification includes obtaining the batch identifier, entry time, and batch size;

[0019] The equipment status acquisition includes acquiring the load of the low-temperature quick-freezing unit, the load of the rewarming and shell-cracking unit, the load of the shell-peeling and separation unit, the occupancy status of the buffer queue, and the occupancy status of the abnormal egg flow channel.

[0020] The time alignment, field mapping, and unified encoding include merging batch information, initial temperature, surface condition, and equipment operating status into the same batch acquisition window and encapsulating them into callable batch records.

[0021] Furthermore, the process of linking condition mapping and rhythm correction includes:

[0022] First, batch verification, field matching verification, and time-series correlation verification are performed. The minimum set of fields for field matching verification includes the shell water content status field, the attachment residue status field, the surface integrity status field, the low-temperature quick-freezing unit load field, and the cache queue occupancy status field.

[0023] Based on the shell's water content, residual adhesion, and surface integrity, a condition mapping is performed to generate the cleaning spray intensity, cleaning dwell time, draining dwell time, loading interval, and tray distribution sequence.

[0024] Based on the load of the low-temperature quick-freezing unit, the load of the rewarming and shell-cracking unit, the load of the shell-peeling and separation unit, the occupancy status of the buffer queue, and the occupancy status of the abnormal egg flow channel, the cycle time correction is performed, and the cleaning spray intensity, cleaning residence time, draining residence time, feeding interval, and tray distribution sequence are adjusted in conjunction with these adjustments.

[0025] Furthermore, the process of tiered warehousing, freezing and maintaining inventory, and matching the outbound cycle includes:

[0026] The layered loading process includes importing the same batch of eggs into the corresponding trays and layers according to the tray correspondence field, and performing position verification to prevent cross-mixing of different batches; the freezing and holding process includes controlling the dwell time in the freezing zone, the dwell time in the isothermal zone, and the tray spacing according to the batch identifier. The tray spacing, the dwell time in the freezing zone, and the dwell time in the isothermal zone together determine the batch dwell state of the current batch inside the low-temperature quick-freezing unit; the unloading cycle matching process includes determining the unloading order and unloading timing based on the receiving space of the rewarming and shell-cracking unit, the queuing status of subsequent batches, and the release status of the preceding tray of this batch, and recording the shell surface hardening status, batch dwell state, and unloading timing during unloading.

[0027] Furthermore, the process of temperature recovery buffering and directional shell cracking includes:

[0028] The reheating buffer includes determining the reheating dwell time, conveying interval, and batch release sequence based on the shell surface hardening state, surface integrity state, adhesion residue state, reheating shell cracking unit load, and shell peeling separation unit load.

[0029] The reheating dwell time, conveying interval, and batch release sequence are related to the feeding rhythm of the subsequent shell-cracking station;

[0030] The directional shell cracking process includes determining the crack location distribution, crack strength, and crack density based on the initial temperature, surface condition, shell surface hardening state, and current equipment operating state, and then applying the cracking action according to the crack location distribution after performing directional positioning at the cracking station.

[0031] Furthermore, the process of flexible shell removal, fragment removal, integrity testing, and anomaly classification includes:

[0032] The flexible desquamation includes controlling the frequency of the flipping and desquamation part and the contact rhythm of the extrusion and desquamation part according to the distribution of the crack location, the crack strength and the crack density.

[0033] The shell removal process includes shell fragment extraction and shell fragment screening at the shell-meat separation station, and separate transport of the egg body and shell fragments.

[0034] The integrity detection includes performing surface inspection and contour recognition, and determining whether it is clean shell recognition, residual shell recognition or damage recognition.

[0035] The anomaly classification includes sending broken egg streams, stuck-shell egg streams, uncleaned-shell egg streams, and insufficiently cracked-shell egg streams into independent diversion channels, secondary warming channels, secondary peeling channels, and supplementary cracked-shell channels, respectively, based on the identification results.

[0036] Furthermore, the process of clock tick construction and cache queue scheduling includes:

[0037] The cycle construction includes merging clean-shell egg streams and abnormal egg streams under the same batch identifier into the same running object, and calculating the clean-shell rate and breakage rate;

[0038] The cache queue scheduling includes dynamically adjusting the release priority of the abnormal egg flow channel and the shell clearing channel according to the abnormal flow order and the shell clearing output order.

[0039] Furthermore, the process of multi-parameter linkage correction and differentiated reflux reprocessing includes:

[0040] The multi-parameter linkage correction includes adjusting the cleaning dwell time, draining dwell time, freezing zone dwell time, uniform temperature zone dwell time, warming dwell time, shell cracking intensity, conveying interval, shell peeling line speed and abnormal egg flow distribution sequence of the next batch based on the shell cleaning rate, breakage rate, line blockage status and equipment load.

[0041] The differentiated reflux reprocessing includes sending the shell-adhered egg stream into the secondary warming channel and writing back the warming residence time correction value, sending the uncleaned egg stream into the secondary peeling channel and writing back the peeling linear speed correction value, and sending the insufficiently cracked egg stream into the supplementary cracking channel and writing back the cracking intensity correction value and the abnormal egg stream distribution order correction value.

[0042] Furthermore, a collaborative production control system for the batch low-temperature quick-freezing and shelling process of quail eggs includes: a batch input set generation module, a pre-processing judgment module, a low-temperature quick-freezing module, a rewarming and shell-cracking module, a shell-peeling and separation module, and a collaborative correction module; the modules are connected in sequence to implement the method described in any of the above-mentioned embodiments.

[0043] The following are its main beneficial effects:

[0044] (1) By linking and layering the raw material status and line load in S200, the pretreatment parameters such as cleaning spray intensity, cleaning residence time, and draining residence time can be dynamically adjusted according to the water content of the eggshells at the front end, the degree of adhesion residue, the surface integrity, and the load of the equipment at the back end. This method solves the problem in the background technology that the station controls are independent of each other and the fixed parameters cannot adapt to changes in the raw material status. It realizes the dynamic matching between the pretreatment stage and the overall line cycle time, and reduces eggshell damage and material blockage caused by incomplete cleaning or improper parameters.

[0045] (2) Through multi-parameter linkage correction and closed-loop write-back of the entire line in S600, nine types of process parameters, such as cleaning dwell time, freezing zone dwell time, reheating dwell time, shell cracking strength, and peeling line speed, can be automatically adjusted according to the net shell rate, breakage rate, line blockage status, and equipment load of the previous batch. This method solves the problem in the background technology that open-loop operation cannot automatically correct parameters based on historical batch results, enabling the system to continuously optimize process parameters and maintain stable peeling quality during long-term operation.

[0046] (3) Through integrity detection and anomaly classification in S500 and differentiated backflow reprocessing in S600, broken egg flows, stuck-shell egg flows, uncleaned-shell egg flows, and insufficiently cracked-shell egg flows are respectively directed to independent diversion channels, secondary warming channels, secondary shell peeling channels, and supplementary cracked-shell channels, and the corresponding correction parameters are written back for different anomaly types. This method solves the problems of single abnormal egg flow processing path and unstable reprocessing effect in the background technology, improves the processing efficiency and reprocessing success rate of abnormal egg flows, and improves the overall clean-shell rate.

[0047] (4) By using the cache queue scheduling and cycle time construction in S600, the release priority of the abnormal egg flow channel and the clean shell channel is dynamically adjusted according to the shell output order, abnormal diversion order, and the cache occupancy status of each workstation. When multiple workstations are congested at the same time, the allocation and outgoing order of the next batch of pallets are postponed. This method solves the problems of lack of cross-workstation cache queue scheduling capability and misalignment of cycle time between workstations in the background technology, ensuring the overall line efficiency and reducing downtime caused by local congestion.

[0048] (5) By tracking and recording batch identification throughout the entire process from S100 to S600, a traceable correlation record is formed between each step of the batch input set, quick-freezing preparation instructions, target frozen egg state records, peelable egg flow records, clean-shell egg flow records, abnormal egg flow records, and overall line collaborative control results. This method solves the problem of isolated data and inability to form closed-loop feedback in the background technology, provides a reliable historical basis for parameter correction, and improves the traceability and control accuracy of the production process.

[0053] Example 1: Refer to Figure 1 This is a flowchart illustrating a collaborative production control method for the batch low-temperature quick-freezing and shelling process of quail eggs provided in an embodiment of the present invention. The process may include at least steps S100-S600:

[0054] S100, based on the collaboration of the workstation for incoming line acquisition, status aggregation and batch input set generation, performs batch identification, equipment status acquisition and time alignment, field mapping and unified encoding to obtain the batch input set;

[0055] S200. Based on the batch input set, perform linkage condition mapping and cycle correction between raw material side status and line side load to obtain quick-freezing preparation instructions.

[0056] S300: Based on the quick-freezing preparation instructions, perform layered storage, freezing and maintenance and outbound rhythm matching to obtain egg products in the target frozen and bulging state;

[0057] S400. Based on the target frozen and swollen egg product, perform warming buffering and directional shell cracking treatment to obtain a peelable egg stream.

[0058] S500: Based on the peelable egg flow, perform flexible shell removal, broken shell removal, integrity detection and abnormal classification to obtain clean shell egg flow and abnormal egg flow;

[0059] S600. Based on the clean egg flow and abnormal egg flow, perform cycle time construction, buffer queue scheduling, multi-parameter linkage correction and differentiated backflow reprocessing to obtain the overall line collaborative control result.

[0060] S100, based on the collaboration of the workstation for incoming line acquisition, status aggregation and batch input set generation, performs batch identification, equipment status acquisition and time alignment, field mapping and unified encoding to obtain the batch input set;

[0061] Specifically, step S100 is set before the quail eggs to be processed enter the cleaning and pre-treatment station, and is completed collaboratively by the inbound data acquisition station, the status aggregation station, and the batch input set generation station. The inbound data acquisition station is located at the beginning of the conveying section and performs batch identification and arrival confirmation on the quail eggs entering the production line; the status aggregation station is connected to the low-temperature quick-freezing unit, the rewarming and shell-cracking unit, the shell-peeling and separation unit, the buffer queue, and the abnormal egg flow channel, and receives the current equipment operating status; the batch input set generation station performs time alignment, field mapping, and unified encoding on the aforementioned acquisition results, and outputs the batch input set. When the incoming conveyor section detects the arrival of a new batch of quail eggs to be processed, or when the previous batch of quail eggs to be processed has been handed over and the batch identifier has been switched, S100 is triggered; when there are missing batch identifiers, missing temperature acquisitions, missing surface status, or equipment operating status timeouts and has not been updated within the same acquisition window, the current writing action is paused, the quail eggs to be processed are kept in the incoming buffer section, and the abnormal records are marked with the batch identifier and then re-acquired, so that the output content of this step and the content called in the subsequent S200 maintain the same source correspondence.

[0062] Furthermore, the batch information includes a batch identifier, entry time, and batch size. The batch identifier is generated by the entry acquisition station according to the entry sequence, combined with batch handover records. These handover records originate from the handover units in the upstream crating, temporary storage, or loading stages, and are written into the batch identifier when the quail eggs to be processed enter the conveyor start section. The entry time is generated by the arrival detector in the conveyor start section when the quail eggs to be processed pass the detection position and is associated with the batch identifier. The batch size is obtained by counting the number of quail eggs to be processed that continuously pass through the conveyor section, with the counting range corresponding to the total number of eggs in the same batch under the same batch identifier. Understandably, the batch information is not simply labeling information, but rather a fundamental organizational field in the batch input set. The batch identifier is used for subsequent batch tracking, the entry time is used for subsequent time alignment, and the batch size is used for subsequent tray loading rhythm and preprocessing load determination. In a real-world engineering scenario, after the shift begins, the material handling personnel pour the cooked quail eggs of the same batch into the inlet buffer hopper. The inlet collection station generates batch identifiers according to the order of arrival, and completes the entry time recording and batch size statistics within the same conveying cycle window. Subsequently, this information is sent to the status aggregation station for further processing in this step.

[0063] Further, the initial temperature includes the egg surface temperature and the inlet temperature. The egg surface temperature is collected by a temperature detector positioned above the inlet sampling station, with the sampling position aligned with the surface of the egg flow on the conveyor belt. The sampling period corresponds to the stable conveying zone before the quail eggs to be processed enter the cleaning and pretreatment station. The inlet temperature is confirmed by the temperature record associated with the batch handover record and the inlet sampling results. Specifically, the temporary temperature record of the batch of quail eggs to be processed before entering the production line is read first, and then the consistency is checked in conjunction with the egg surface temperature. When the two deviate from the allowable range of the current conveying cycle, the batch data is marked as pending verification and sampled again. The surface condition includes the shell moisture content, the residue adhesion, and the surface integrity. The shell moisture content is determined by surface wetness detection and conveyor belt liquid trace identification. The residue adhesion is determined by identifying whether there are stains, shell fragments, and residual adhesion film on the eggshell surface. The surface integrity is determined by identifying whether there are pre-cracks, dents, local breaks, and missing corners on the eggshell. The initial temperature and the surface condition are bound and recorded in the same batch window in this step, and uniformly attached to the batch identifier, so that the same batch of quail eggs to be processed has complete front-end status information when entering S200.

[0064] Furthermore, the equipment operating status includes the load of the low-temperature quick-freezing unit, the load of the rewarming and shell-cracking unit, the load of the shell-peeling and separation unit, the occupancy status of the buffer queue, and the occupancy status of the abnormal egg flow channel. The load of the low-temperature quick-freezing unit is characterized by the current number of trays in the low-temperature quick-freezing unit, the occupancy status of the freezing zone, and the number of batches awaiting shipment. The load of the rewarming and shell-cracking unit is characterized by the number of batches in the rewarming buffer zone, the queue length at the shell-cracking station, and the current conveying interval. The load of the shell-peeling and separation unit is characterized by the current processing cycle of the flexible shell-peeling station, the occupancy status of the shell-meat separation station, and the queue status of the integrity detection station. The occupancy status of the buffer queue is characterized by the number of occupants in the inlet buffer section, the pre-buffer section of the low-temperature quick-freezing unit, and the pre-buffer section of the rewarming and shell-cracking unit. The occupancy status of the abnormal egg flow channel is characterized by its current opening status, the number of eggs in transit, and its pending clearing status. The status aggregation station reads the aforementioned equipment operating status according to a unified acquisition clock and correlates the reading results with the batch identifier and the inlet time, ensuring that the equipment operating status is aligned with the current batch of quail eggs to be processed under the same time reference. If the operating status of a certain device is not updated in the current acquisition window, the status aggregation station marks the field as invalid and calls the most recent valid status for temporary placeholder, while triggering a reread action; if the reread still does not return a valid result, the batch of quail eggs to be processed will continue to stay in the inlet buffer section and will not enter the formal writing stage of the batch input set generation station.

[0065] Specifically, the time alignment, field mapping, and unified encoding are performed by the batch input set generation station. The time alignment addresses the inconsistency in the acquisition times of batch information, initial temperature, surface condition, and equipment operating status by merging data from various sources into the same batch acquisition window. The window start point is the entry time, and the window end point is the time when the equipment operating status is read. The field mapping maps content from different acquisition sources to fixed field names, including batch identifier, entry time, batch size, egg surface temperature, entry temperature, shell moisture content, attachment residue status, surface integrity status, low-temperature quick-freezing unit load, rewarming and cracking unit load, shell peeling and separation unit load, buffer queue occupancy status, and abnormal egg flow channel occupancy status. The unified encoding encapsulates the above fields using the same record format, making each field under the same batch identifier a traceable, callable, and rewritable batch record. After completing the time alignment, field mapping, and unified encoding, the batch input set generation station outputs the batch input set and sends it to the preprocessing determination unit in S200. The batch identifier field, the shell moisture content field, the adhesion residue field, the surface integrity field, and the equipment operating status field are used in S200 as direct inputs to determine the cleaning preprocessing conditions and draining conditions. The line entry time field and the batch size field are used in S200 as associated inputs to the loading interval and tray allocation order, thus establishing a clear cross-step input relationship between the output product of this step and subsequent main steps.

[0066] In a complete engineering embodiment, quail eggs to be processed are temporarily stored in turnover baskets after cooking and pre-cooling. Workers guide the same batch of turnover baskets into the initial conveyor section. The data acquisition station reads the batch handover record corresponding to the turnover basket to form the batch identifier, and simultaneously records the entry time and calculates the batch size. Subsequently, a temperature detector collects the surface temperature of the quail eggs to be processed on the conveyor belt and checks the entry temperature against the record in the temporary storage area. A surface condition detector identifies the degree of wetness, adhesion residue, and pre-crack condition of the shell surface, generating a data set on the shell's moisture content. The system considers the water state, the state of any attached residue, and the state of the surface integrity. The status aggregation station synchronously reads the current occupancy status of the low-temperature quick-freezing unit, the rewarming and shell-cracking unit, the shell-peeling and separation unit, the buffer queue, and the abnormal egg flow channel. After completing time alignment, field mapping, and unified encoding, the batch input set generation station outputs a batch input set corresponding to the current batch and directly pushes it to the pre-processing judgment unit in S200. S200 then determines the cleaning spray intensity, cleaning dwell time, draining dwell time, loading interval, and tray allocation order based on this record. If, in this engineering embodiment, the surface integrity status shows a high pre-crack ratio, or the abnormal egg flow channel is in a congested state, the current batch is synchronously written with an abnormal record in the batch input set, allowing the subsequent pre-processing judgment unit to adjust the corresponding processing rhythm when called upon.

[0067] The technical effect of this step can be summarized as follows: Step S100 organizes the batch information, initial temperature, surface condition, and equipment operating status of the quail eggs to be processed into the same batch input set, enabling subsequent preprocessing judgments to be based on data from the same batch. Step S100 binds the raw material side status and the production line side status into the same step, giving the batch input set both batch tracking and process calling relationships. The output fields of S100 correspond one-to-one with the input positions of S200, providing a basis for continuous transmission and closed-loop calling in subsequent steps.

[0068] S200. Based on the batch input set, perform linkage condition mapping and cycle correction between raw material side status and line side load to obtain quick-freezing preparation instructions.

[0069] The S200 receives the batch input set output by the S100 and is executed by the preprocessing determination unit between the inlet buffer section and the cleaning preprocessing station. Specifically, the preprocessing determination unit receives the batch identifier field, inlet time field, batch size field, egg surface temperature field, inlet temperature field, shell moisture content field, attachment residue status field, surface integrity status field, low-temperature quick-freezing unit load field, rewarming cracked shell unit load field, shell peeling and separation unit load field, buffer queue occupancy status field, and abnormal egg flow channel occupancy status field from the batch input set, and performs batch verification, field matching verification, and time sequence correlation verification on each field under the same batch identifier. The batch verification checks whether the batch identifier matches the current egg flow in the inbound buffer. The field matching verification checks whether the batch input set contains the minimum set of fields required for the current determination. The minimum set of fields includes the shell water content status field, the attachment residue status field, the surface integrity status field, the low-temperature quick-freezing unit load field, and the buffer queue occupancy status field. The timing correlation verification checks whether the inbound time field is continuous with the current inbound buffer dwell time period. When the batch verification, the field matching verification, and the timing correlation verification all pass, the formal determination of this step is initiated. When any verification fails, the preprocessing determination unit freezes the current batch write operation, retains the batch identifier, and generates an exception record. The determination process is restarted after the batch input set is completed.

[0070] Specifically, the pre-treatment conditions are the process arrangements executed at the pre-treatment station before the quail eggs to be processed enter the low-temperature quick-freezing unit, including the cleaning spray intensity, cleaning dwell time, and feeding interval; the draining conditions are the process arrangements executed at the draining section after the quail eggs to be processed leave the pre-treatment station, including the draining dwell time and tray distribution order. The pre-treatment determination unit first reads the shell moisture content field to identify the liquid distribution on the surface of the quail eggs to be processed, the moisture distribution of the shell, and the draining start state; then it reads the attachment residue state field to identify the distribution of attachments, shell fragments, and residual film on the eggshell surface; subsequently, it reads the surface integrity state field to identify pre-cracks, dents, local breaks, and missing corners; finally, it reads the low-temperature quick-freezing unit load field, the rewarming cracking unit load field, the shell peeling and separation unit load field, the buffer queue occupancy state field, and the abnormal egg flow channel occupancy state field to identify the current cleaning cycle time, draining cycle time, and feeding cycle time that the entire line can handle. The shell moisture content field, the adhesion residue field, and the surface integrity field constitute the raw material side judgment criteria, and the equipment operation status related fields constitute the line body side judgment criteria. The pretreatment judgment unit generates the cleaning spray intensity, cleaning residence time, draining residence time, feeding interval, and tray distribution sequence in the order of "judging the raw material side first and repairing the line body side later" to avoid the disconnect between the front-end raw material status and the back-end receiving status.

[0071] Furthermore, the pretreatment determination unit performs conditional mapping on the shell moisture content field, the attachment residue field, and the surface integrity field. If the shell moisture content field shows continuous liquid on the shell surface, the pretreatment determination unit reduces the cleaning spray intensity and extends the draining time to prevent liquid-laden eggs from directly entering the subsequent feeding area. If the attachment residue field shows concentrated distribution of attachments, the pretreatment determination unit increases the cleaning spray intensity and extends the cleaning time to ensure that the attachments detach before entering the silo. If the surface integrity field shows pre-cracks, missing corners, or local breaks, the pretreatment determination unit reduces the cleaning spray intensity and simultaneously increases the feeding interval to maintain a slower conveying pace for quail eggs with poor surface integrity in the cleaning pretreatment station and draining section. Understandably, the cleaning spray intensity, the cleaning dwell time, and the draining dwell time are the core parameter set of this step, and the three directly determine the surface cleanliness and surface liquid state of the quail eggs to be processed before entering the low-temperature quick-freezing unit; the feeding interval and the tray distribution sequence are configuration parameters linked to the overall line cycle, used to introduce the same batch of quail eggs to be processed into the low-temperature quick-freezing unit according to the current line state.

[0072] Furthermore, the preprocessing determination unit performs cycle time correction on the relevant fields of the equipment operating status. If the load field of the low-temperature quick-freezing unit shows that the number of trays waiting to be loaded into the freezing area is too high, the preprocessing determination unit extends the draining dwell time and widens the feeding interval to keep the egg flow from the buffer section to the low-temperature quick-freezing unit in sequence. If the buffer queue occupancy status field shows that the buffer section in front of the low-temperature quick-freezing unit is almost full, the preprocessing determination unit reorders the tray allocation order so that the current batch occupies the free tray position first, and the egg flow without allocated tray position remains waiting in the draining section. If the load field of the rewarming and shell-cracking unit and the load field of the shell-peeling and separation unit both increase, the preprocessing determination unit compresses the feeding cycle time density of the current batch to prevent subsequent multi-station queues from overlapping. If the abnormal egg flow channel occupancy status field shows that the abnormal egg flow channel is being emptied, the preprocessing determination unit places the quail eggs with poor surface integrity in a later position in the subsequent tray allocation order so that the abnormal egg flow channel and the normal egg flow channel maintain staggered peaks in subsequent operation. The cycle correction is not an independent action, but rather a coordinated correction performed on the cleaning spray intensity, cleaning dwell time, draining dwell time, feeding interval, and tray distribution sequence after the condition mapping is completed, so that the quick-freezing preparation command simultaneously reflects the raw material side status and the line side status.

[0073] Specifically, the pre-freezing preparation instructions are written into a fixed instruction structure by the pretreatment determination unit. This fixed instruction structure includes a batch identifier field, a pretreatment parameter field, a feeding sequence field, and a tray correspondence field. The pretreatment parameter field contains the cleaning spray intensity, cleaning dwell time, and draining dwell time. The feeding sequence field contains the feeding interval, the start feeding time, and the batch release order. The tray correspondence field contains the correspondence between the batch identifier and each tray number, and records the arrangement position of the same batch on different tray layers. After completing the instruction writing, the preprocessing judgment unit performs a readback verification on the pre-freezing preparation instruction. This verifies whether the batch identifier field matches the current batch in the buffer section, whether the preprocessing parameter field conflicts with the current equipment operating status, and whether there is any overlap between the feeding sequence field and the pallet correspondence field. When the readback verification passes, the pre-freezing preparation instruction is output and sent to the low-temperature quick-freezing unit in S300. The pallet correspondence field is used for layered warehousing in S300, the feeding sequence field is used for outbound rhythm matching in S300, and the preprocessing parameter field serves as the basis for S300 to determine the target frozen egg product's pre-batch status.

[0074] In one engineering embodiment, after cooling, the same batch of quail eggs enters the inlet buffer section. The batch input set generated by S100 shows that the shell water content field indicates continuous liquid on the surface, the adhesion residue field indicates localized adhesion residue on the shell, the surface integrity field indicates a small amount of pre-cracks, the low-temperature quick-freezing unit load field indicates queuing in the freezing zone, and the buffer queue occupancy field indicates high occupancy in the buffer section before the low-temperature quick-freezing unit. The pretreatment judgment unit first reduces the washing spray intensity by one level to avoid additional impact on the pre-cracked eggshells, then maintains the washing dwell time at the standard time period for the current batch, and extends the draining dwell time to ensure that the surface liquid is released before entering the storage. Subsequently, the loading interval is increased, and the tray allocation order is rearranged according to the available tray positions, so that the same batch of quail eggs enters the low-temperature quick-freezing unit in the order of washing first, then draining, and then loading in batches. The pre-processing determination unit generates the quick-freezing preparation instruction accordingly, and sends the batch identifier field, pre-processing parameter field, feeding sequence field and pallet correspondence field to S300, so that S300 performs layered warehousing, freezing and holding and warehousing rhythm matching according to the current batch status.

[0075] The technical effect of this step can be summarized as follows: Step S200 converts the batch input set formed in Step S100 into directly executable pre-freezing preparation instructions, thus establishing a substantial connection between front-end status acquisition and subsequent low-temperature quick-freezing operation. Step S200 processes cleaning spray intensity, cleaning residence time, draining residence time, loading interval, and tray allocation sequence within the same decision link, enabling the raw material-side status and line-side status to be linked within this step. The output fields of Step S200 directly correspond to the calling positions in Step S300, providing a continuous input basis for the pre-freezing preparation instructions in subsequent layered warehousing, freeze holding, and outbound cycle matching.

[0076] S300: Based on the quick-freezing preparation instructions, perform layered storage, freezing and maintenance and outbound rhythm matching to obtain egg products in the target frozen and bulging state;

[0077] The S300 receives the pre-freezing preparation command output by the S200 and is continuously executed by the low-temperature quick-freezing unit in the feeding section, freezing zone, temperature equalization zone, and outlet. Specifically, the low-temperature quick-freezing unit receives the batch identifier field, pre-processing parameter field, feeding sequence field, and tray correspondence field from the pre-freezing preparation command, and initiates the hopper entry process when the current batch arrives at the feeding section. The batch identifier field is used to identify the batch to which the quail eggs to be processed currently entering the low-temperature quick-freezing unit belong; the pre-processing parameter field is used to identify the basic surface state of the batch after cleaning pre-processing and draining; the feeding sequence field is used to constrain the order in which the current batch enters the low-temperature quick-freezing unit; and the tray correspondence field is used to limit the arrangement relationship of the current batch on different trays and different layers. After reading the aforementioned fields, the low-temperature quick-freezing unit first executes an instruction verification. The verification includes whether the batch identifier field is consistent with the egg flow in the feeding section, whether the feeding sequence field conflicts with the current outlet release capacity, and whether the pallet correspondence field corresponds with the position of the idle pallet. When the verification passes, the unit proceeds to the layered warehousing process. When the verification fails, the low-temperature quick-freezing unit retains the current batch in the feeding section and writes the conflict record back to the current batch record.

[0078] Specifically, the layered loading refers to the process of guiding the quail eggs to be processed into the corresponding trays and layers according to the tray correspondence. After reading the tray correspondence field in the feeding section, the low-temperature quick-freezing unit first separates the egg streams according to batch identifiers, and then sends the egg streams of the same batch into the corresponding trays according to the tray numbers and layer order recorded in the tray correspondence field. For different layers within the same tray, the low-temperature quick-freezing unit loads layer by layer according to a predetermined conveying rhythm, and performs a position check after each layer is loaded to prevent cross-contamination between different batches. The layered loading is not a simple tray loading action, but rather keeps quail eggs with similar states within the same batch running under the same freezing path, so that the subsequent freezing process corresponds to the same batch and the same tray relationship. If the pallet correspondence field indicates that the current batch needs to be allocated to multiple pallets, the low-temperature quick-freezing unit feeds in batches according to the order of the feeding sequence field. If the number of currently available pallets is less than the number required by the pallet correspondence field, the subsequent egg flow is paused, the loaded portion is registered as the preceding pallet of the current batch, and the unit waits for the next available pallet to continue loading. The waiting status is synchronously recorded in the current batch record for matching and calling the subsequent outbound cycle of this step.

[0079] Furthermore, the freezing and holding process refers to the controlled batch-by-batch dwelling of trays that have completed layering and storage within the freezing and equalization zones. After a tray enters the freezing zone, the low-temperature quick-freezing unit controls the dwell time in the freezing zone according to the batch identifier, and after the tray leaves the freezing zone, it controls the dwell time in the equalization zone according to the same batch identifier. The dwell time in the freezing zone corresponds to the cooling process of the outer shell and the surface of the egg, while the dwell time in the equalization zone corresponds to the temperature transfer balancing process of egg flow at different layers within the same tray. During the freezing and holding period, the low-temperature quick-freezing unit synchronously controls the tray spacing, which is the interval between adjacent trays in the transport direction. The tray spacing, along with the dwell time in the freezing zone and the dwell time in the equalization zone, jointly determines the batch dwelling status of the current batch within the low-temperature quick-freezing unit. If there are already trays waiting to be unloaded in front of the freezing zone, the low-temperature quick-freezing unit will increase the spacing between subsequent trays; if there are empty spaces in the equalization zone, the low-temperature quick-freezing unit will advance the preceding trays in the current batch order, ensuring continuous flow between the freezing and equalization zones. Understandably, the duration of stay in the freezing zone, the duration of stay in the temperature equalization zone, the tray spacing, and the order of exiting the warehouse constitute the minimum set of core parameters for this step, and the aforementioned parameters directly participate in the determination of the formation of the target frozen and bloated egg product.

[0080] Furthermore, the outbound cycle matching is a process of coordinating the outbound sequence and timing after the trays have completed freezing and holding. The cryogenic quick-freezing unit reads the batch identifier of the current tray at the outlet of the uniform temperature zone and, in conjunction with the available receiving slots in the subsequent rewarming and shell-cracking unit, the queuing status of subsequent batches in the current feeding section, and the release status of the preceding trays in this batch, determines the outbound sequence of the current tray. The outbound sequence is used to limit the order of departure between different trays of the same batch and between trays of different batches, while the outbound timing is used to limit the time relationship between adjacent trays leaving the outlet. If trays of the same batch are entered in segments, the cryogenic quick-freezing unit prioritizes maintaining the continuous release of the same batch at the outlet; if there are no available slots in the subsequent receiving section, the dwell time of the current tray at the end of the uniform temperature zone is extended, and this dwell time is registered as part of the batch dwell status. After the outbound cycle matching is completed, the cryogenic quick-freezing unit performs a status determination on the current batch, which includes the shell surface hardening status, batch dwell status, and outbound timing. The surface hardening state of the shell is recorded based on the degree of surface hardening after passing through the freezing zone and the surface stability state at the end of the isothermal zone. The batch dwell state is recorded based on the actual dwell time of the current batch in the freezing zone, isothermal zone, and the waiting section at the end of the isothermal zone. The exit sequence is recorded based on the order in which the current pallet leaves the exit port.

[0081] Specifically, the target frozen-swelling state egg product is the batch output product after the layered storage, freezing and holding, and outbound cycle matching are completed, and is not simply an egg product that has undergone low-temperature treatment. When the current tray leaves the outbound port, the low-temperature quick-freezing unit registers the egg flow corresponding to the tray as the target frozen-swelling state egg product and simultaneously generates a target frozen-swelling state egg product record. The target frozen-swelling state egg product record includes a batch identifier field, a shell surface hardening state field, a batch dwell state field, and an outbound sequence field. The batch identifier field is used for subsequent batch tracking, the shell surface hardening state field is used by S400 to determine the shell membrane separation requirement, the batch dwell state field is used by S400 to adjust the rewarming dwell time, and the outbound sequence field is used by S400 to arrange the batch release order. When the low-temperature quick-freezing unit outputs the target frozen-swelled egg product, it sends the target frozen-swelled egg product and its record together to the rewarming and shell-cracking unit in S400. The target frozen-swelled egg product serves as the feed object of the rewarming buffer. The shell surface hardening state field, the batch dwell state field, and the out-of-warehouse sequence field serve as direct inputs in S400 to determine the shell membrane separation requirements and control the batch release order.

[0082] In one engineering embodiment, the pre-freezing preparation instruction output by S200 records the corresponding relationship of the current batch of trays as two sets of trays, with the same batch continuously entering the warehouse, and the loading sequence being the first set followed by the second set. The low-temperature quick-freezing unit first reads the batch identifier field and tray correspondence field of the first set of trays in the loading section, loads the batch of egg flow into the first set of trays according to layer, and then loads the subsequent egg flow into the second set of trays. In the freezing zone, the first set of trays operates according to the freezing zone dwell time corresponding to the current batch, and in the uniform temperature zone, it operates according to the uniform temperature zone dwell time corresponding to the same batch. When a short queue occurs in the subsequent rewarming and shell-cracking unit, the first set of trays briefly pauses at the end of the uniform temperature zone. The low-temperature quick-freezing unit writes this pause into the batch dwell status field and appropriately increases the tray spacing of the second set of trays. After the rewarming and shell-cracking unit releases empty space, the first set of trays leaves the outlet first, and the second set of trays leaves sequentially according to the exit order. The low-temperature quick-freezing unit records the shell surface hardening state, batch dwell state, and out-of-warehouse sequence of each batch when each tray leaves the warehouse, and then sends the corresponding egg flow as the target frozen swelling state egg product into S400.

[0083] The technical effect of this step can be summarized as follows: S300 converts the pre-freezing preparation instructions into the target frozen-bulking state of the eggs, enabling continuous operation of feeding, freezing, and release within the same batch process. S300 integrates layered loading, freezing, and release timing into a single step, establishing batch-related relationships between trays, storage, and departure. The target frozen-bulking state of the eggs output by S300 and its recorded content are directly linked to the rewarming buffer and shell membrane separation requirements in S400.

[0084] S400. Based on the target frozen and swollen egg product, perform warming buffering and directional shell cracking treatment to obtain a peelable egg stream.

[0085] S400 receives the target frozen-heavy state egg product and the target frozen-heavy state egg product record output by S300, and the rewarming and shell-cracking unit continuously completes the process in the rewarming buffer and shell-cracking station. Specifically, the rewarming and shell-cracking unit receives the batch identifier field, shell surface hardening state field, batch dwell state field, and out-of-warehouse sequence field from the target frozen-heavy state egg product record, and simultaneously retrieves the initial temperature field, surface state field, and equipment operating status field from the batch input set formed by S100, wherein the equipment operating status field includes at least the rewarming and shell-cracking unit load field and the shell-peeling and separation unit load field. When the current batch arrives at the inlet of the warming and cracking unit, the shell membrane separation requirement determination process is initiated. First, the batch identification field is checked to see if it matches the current egg flow. Then, the out-of-warehouse sequence field is checked to see if it matches the queuing order at the inlet of the warming buffer. When the checks pass, the egg surface temperature and inlet temperature in the initial temperature field are read, the shell moisture content, residual adhesion, and surface integrity in the surface state field are read, and the shell surface hardening state field is read. Combined with the load field of the warming and cracking unit and the load field of the shell peeling and separation unit, the shell membrane separation requirement for the current batch is determined. The shell membrane separation requirement refers to the batch control content adopted by the rewarming and cracking unit when performing rewarming buffering and directional cracking on the target frozen and swollen eggs. It includes the rewarming dwell time, crack location distribution, crack intensity, and crack density. The rewarming dwell time represents the dwell arrangement of the current batch in the rewarming buffer, the crack location distribution represents the distribution area of ​​cracks on the eggshell surface, the crack intensity represents the impact of the cracking station on the eggshell surface, and the crack density represents the density of cracks formed on a unit eggshell surface.

[0086] Specifically, the warming buffer is the process of releasing, holding, and outputting the target frozen-bulking eggs in batches within the warming buffer in sequence. After determining the shell membrane separation requirement, the warming and shell-cracking unit imports the current batch into the warming buffer according to the batch identifier field and schedules it according to the warming hold time, conveying interval, and batch release order. The conveying interval is determined by the warming and shell-cracking unit in conjunction with the out-of-warehouse sequence field, the load field of the warming and shell-cracking unit, and the load field of the shell-peeling and separating unit. When the load field of the shell-peeling and separating unit shows an increase in the queue at subsequent workstations, the warming and shell-cracking unit increases the conveying interval; when the load field of the warming and shell-cracking unit shows an accumulation of egg flow at the inlet of this workstation, the warming and shell-cracking unit compresses the waiting gap between adjacent batches without changing the batch release order. The batch release order maintains the out-of-warehouse relationship of consecutive batches according to the out-of-warehouse sequence field, ensuring continuous release within the same batch and sequential isolation between different batches. If the surface integrity status field indicates that the current batch has pre-cracked distribution, the reheating and cracking unit extends the reheating dwell time and reduces the pushing rhythm within the reheating buffer. If the shell surface hardening status field indicates that the current batch has a high degree of hardening, the reheating and cracking unit extends the reheating dwell time and increases the conveying interval. If the adhesion residue status field indicates that there is a lot of adhesion residue, the reheating and cracking unit adds a short dwell time at the end of the reheating buffer for this batch, and the short dwell time is included in the reheating dwell time record. Understandably, the reheating dwell time, the conveying interval, and the batch release order constitute the core parameter set of the first half of this step, and the three are directly related to the feeding rhythm of the subsequent cracking station and the egg flow status of the same batch.

[0087] Furthermore, the directional shell cracking is a process in which eggs, after completing the rewarming buffer, undergo batch-by-batch crack formation control at the shell cracking station. After the current batch completes the rewarming buffer, the rewarming shell cracking unit sends the batch of eggs to the shell cracking station according to the batch release order, and performs directional shell cracking according to the crack location distribution, crack intensity, and crack density. The crack location distribution is determined by the rewarming shell cracking unit based on the initial temperature field, the surface state field, and the shell surface hardening state field; the crack intensity is determined by the actual dwell state of the current batch in the rewarming buffer and the current processing cycle of the shell cracking station; the crack density is generated by the linkage between the crack location distribution and the crack intensity. After receiving the eggs, the shell-cracking station first performs orientation and positioning to maintain the eggs in a predetermined posture within the conveyor channel, and then applies shell-cracking actions according to the specified cracking position distribution. When the surface integrity field indicates that there are many local pre-cracks in the current batch, the shell-cracking station reduces the cracking intensity and increases the crack density. When the shell surface hardening state field indicates that the hardening degree of the current batch is low, the shell-cracking station increases the cracking intensity and tightens the cracking rhythm between adjacent eggs. When the shell-peeling and separation unit load field indicates that the receiving capacity of subsequent stations decreases, the shell-cracking station maintains the current cracking position distribution unchanged and extends the cracking interval between adjacent eggs, so that the egg flow after cracking is connected with the entry rhythm of subsequent stations. If the shell-cracking station detects an egg flow pause, posture deviation, or incomplete cracking action in the current batch, it performs a supplementary positioning for the corresponding egg, and then continues to complete the cracking action according to the original cracking position distribution, and records this processing in the current batch record.

[0088] Specifically, after the reheating and shell-cracking unit completes directional shell cracking in the current batch, it generates the peelable egg stream and simultaneously generates a peelable egg stream record. The peelable egg stream record includes a batch identifier field, a reheating dwell time field, a conveying interval field, a batch release order field, a shell crack location distribution field, a shell crack strength field, and a crack density field. The batch identifier field is used for subsequent batch tracking. The reheating dwell time field, the shell crack location distribution field, the shell crack strength field, and the crack density field are used by the flexible shelling station in S500. The conveying interval field and the batch release order field are used by the shell-meat separation station and the integrity detection station in S500. When outputting the peelable egg stream, the reheating and shell-cracking unit sends the egg stream to the shell-separation unit in S500 according to the batch release order and simultaneously writes the peelable egg stream record into the current batch association record, so that S500 can directly correspond to the shell cracking state and conveying state of the current batch when receiving the egg stream.

[0089] In one engineering embodiment, after a batch of eggs in the target frozen state leaves the warehouse from S300, it enters the rewarming buffer. The record of the eggs in the target frozen state shows that the shell surface hardening state of this batch is too high and there is an additional stop at the end of the uniform temperature zone in the batch's dwell state. The batch input set in S100 shows that the surface temperature of the eggs in this batch is too low and the surface integrity state is good. Moreover, the load field of the peeling and separation unit is currently at a high level. The warming and shell-cracking unit first imports the batch into the warming buffer according to the batch identification field, extends the warming residence time, and increases the conveying interval, so that the same batch of eggs is released slowly in a continuous sequence. After the batch completes the warming buffer, it is sent to the shell-cracking station. The shell-cracking station completes directional shell cracking by using a more uniform shell cracking position distribution, a moderate shell cracking intensity, and a sparser crack density, based on the shell surface hardening state of the batch and the current load of the subsequent stations. The egg stream after shell cracking is registered as the peelable egg stream and sent to the shell-peeling separation unit in S500 along with the peelable egg stream record.

[0090] The technical effect of this step can be summarized as follows: Step S400 converts the target frozen-bulky egg product formed in Step S300 into a peelable egg stream that can directly enter the shelling and separation unit, creating a continuous connection between the low-temperature quick-freezing state and the subsequent shelling state. Step S400 processes the rewarming buffer and directional shell cracking within the same batch control link, ensuring that the rewarming time, crack location, and crack state are all constrained by the shell membrane separation requirements. The peelable egg stream output by Step S400 and its recorded content directly correspond to the flexible shelling, broken shell removal, and integrity detection in Step S500.

[0091] S500: Based on the peelable egg flow, perform flexible shell removal, broken shell removal, integrity detection and abnormal classification to obtain clean shell egg flow and abnormal egg flow;

[0092] The S500 receives the peelable egg stream and its record from the S400, and the peeling separation unit continuously completes the process at the flexible shelling station, shell-meat separation station, and integrity detection station. Specifically, when the current batch enters the inlet conveyor section, the peeling separation unit reads the batch identifier field, reheating dwell time field, conveying interval field, batch release sequence field, crack location distribution field, crack strength field, and crack density field from the peelable egg stream record, and performs batch verification, cycle time verification, and sequence verification with the current egg stream on the inlet conveyor section. The batch verification checks whether the batch identifier field matches the inlet egg stream's attribution; the cycle time verification checks whether the conveying interval field matches the current flexible shelling station's receiving interval; and the sequence verification checks whether the batch release sequence field matches the current conveying sequence. When the batch verification, the cycle verification, and the sequence verification all pass, the flexible shelling, broken shell removal, integrity detection, and anomaly classification processing are initiated. When any verification fails, the shelling and separation unit suspends the current egg flow from entering the flexible shelling station and writes the abnormal status into the current batch association record. The process continues after the inlet egg flow is realigned.

[0093] Specifically, the flexible shelling process involves the process of flipping and separating the peelable eggs after they enter the flexible shelling station, according to the current batch's cracked shell state, and then squeezing them out. The flexible shelling station consists of a feeding guide, a flipping and separating section, a squeezing and shelling section, and a posture verification section. The feeding guide guides the peelable egg stream in a single-row configuration. The flipping and separating section rotates the eggs and lifts loosened shells. The squeezing and shelling section applies continuous pressure to cracked eggshells. The posture verification section identifies whether the eggs are tilted, stuck, or under-flipped. The flexible shelling station first determines the priority stress area for the current batch of eggs based on the crack location distribution field, and then determines the separating frequency of the flipping and separating section and the contact rhythm of the squeezing and shelling section based on the crack strength field and the crack density field, ensuring that the same batch of eggs passes through sequentially according to the batch release order. If the crack density field indicates a sparse crack distribution, the flipping and separating section extends the single-egg separating stroke and sets the contact frequency of the squeezing and shelling section to a slower pace. If the shell crack strength field indicates a strong initial crack, the flipping and separating section shortens the single-egg separating stroke and adjusts the contact frequency of the squeezing and shelling section to a lighter pace. If the warming dwell time field indicates a longer dwell time for the current batch, the attitude verification section increases the frequency of verifying the loose shell state on the surface, allowing the loose shell pieces to enter the subsequent extraction path first. Understandably, flipping and separating, and squeezing and shelling constitute the minimum set of actions for the flexible shelling station. The former is responsible for lifting the crack edges, and the latter is responsible for gradually peeling the eggshell from the egg surface. Both operate continuously under the constraint of the batch release sequence.

[0094] Furthermore, the shell fragment removal is completed at the shell-meat separation station. The shell-meat separation station consists of a shell extraction section, a shell fragment screening section, and a transition conveying section. The shell extraction section pulls the outer shell fragments processed by the flexible shelling station from the egg surface. The shell fragment screening section separates the detached shell fragments and shell debris from the egg conveying path. The transition conveying section maintains continuous conveying of clean-shelled eggs and eggs to be judged. After receiving the egg flow from the flexible shelling station, the shell-meat separation station first maintains the egg spacing according to the conveying interval field, and then the shell extraction section performs an extraction action along the edge direction of the remaining shell fragments on the egg surface. After extraction, the shell fragment screening section diverts the extracted shell fragments and shell debris through a channel and conveys the egg separately from the shell fragments. If the egg body output from the flexible shelling station still has fragments of shell on its surface, the shell extraction section repeats the extraction action once more before sending it to the broken shell screening section. If the broken shell screening section detects that broken shell fragments accumulate at the inlet of the transition conveyor section, it briefly reduces the pace of the preceding egg flow and records this pace adjustment in the current batch operation record. After the shell-meat separation station completes its processing, it outputs an intermediate egg flow, which includes eggs without obvious free shell fragments on their surface, and sends them to the integrity detection station in the original batch release order.

[0095] Furthermore, the integrity detection is a process of performing residual shell identification, damage identification, and clean shell identification on the intermediate egg stream at the integrity detection station. The integrity detection station consists of a surface inspection unit, a contour recognition unit, a sorting execution unit, and a result writing unit. The surface inspection unit is used to identify whether residual shells are attached to the egg surface; the contour recognition unit is used to identify whether the egg is damaged, has broken pieces, has crushed cracks, or has localized collapse; the sorting execution unit is used to guide the eggs into the corresponding output channel according to the identification results; and the result writing unit is used to write the identification results for the current batch. The integrity detection station first retrieves the corresponding cracked shell status record for the current batch according to the batch identifier field, and then performs surface inspection and contour recognition on each egg. When the surface inspection result shows that there are no obvious residual shells on the shell surface, and the contour recognition result shows that the egg surface is intact, it is determined to be clean shell identification; when the surface inspection result shows that there are still residual shells attached to the shell surface, it is determined to be residual shell identification; when the contour recognition result shows that the egg has cracks, broken pieces, or localized collapse, it is determined to be damaged identification. After completing the single-egg judgment, the integrity detection station writes the identification results into the result writing unit in batch order, and simultaneously forms the clean shell judgment record and the anomaly judgment record for the current batch. The clean shell judgment record corresponds to the subsequent clean shell egg stream, and the anomaly judgment record corresponds to the subsequent abnormal egg stream.

[0096] Specifically, the anomaly classification is a process of further subdividing abnormal eggs according to their anomaly type after the initial judgment is completed at the integrity detection station. The anomaly classification revolves around broken egg flows, shell-adhered egg flows, uncleaned shell flows, and insufficiently cracked shell flows. Broken egg flows refer to collections of eggs identified by the contour recognition unit as having cracks, missing pieces, or partial collapses. Shell-adhered egg flows refer to collections of eggs identified by the surface inspection unit as having shells partially adhered to the egg surface and still retaining sheet-like shell membranes after removal. Uncleaned shell flows refer to collections of eggs with residual shells still attached after processing at the flexible shell removal station and the shell-meat separation station, but with intact egg contours. Insufficiently cracked shell flows refer to collections of eggs where the cracks have not fully developed after the previous directional shell-cracking treatment, and the current surface inspection unit identifies that the entire shell layer has not formed an effective loosened area. According to the aforementioned classification results, the sorting execution unit inputs the broken egg stream into an independent diversion channel, the stuck-shell egg stream into a secondary reheating channel, the uncleaned-shell egg stream into a secondary peeling channel, and the insufficiently cracked-shell egg stream into a crack-supplementation channel. After the anomaly classification is completed, the result writing unit writes the quantity, batch sequence position, and diversion destination corresponding to each anomaly type into the current batch operation record, which is then available for use by the collaborative correction unit in S600.

[0097] Specifically, after completing the flexible shelling, broken shell removal, integrity detection, and anomaly classification, the shell-peeling and separation unit generates the cleaned egg stream and the abnormal egg stream. The cleaned egg stream is the collection of eggs that enter the cleaned egg output channel after being identified by the cleaned shell identification process, and the abnormal egg stream is the collection of eggs that enter the abnormal output channel after being classified as abnormal. The shell-peeling and separation unit simultaneously generates cleaned egg stream records and abnormal egg stream records. The cleaned egg stream record includes a batch identifier field, a cleaned shell quantity field, a cleaned shell output order field, and a station passage time field. The abnormal egg stream record includes a batch identifier field, an anomaly type field, an anomaly quantity field, an anomaly diversion order field, and an anomaly destination field. After leaving the integrity detection station, the cleaned egg stream and the abnormal egg stream are sent to the collaborative correction unit in S600. The cleaned egg quantity field and the abnormal egg quantity field are used by S600 to calculate the cleaned egg rate and the breakage rate. The abnormality type field and the abnormality destination field are used by S600 to perform reflow processing and parameter correction. The cleaned egg output order field and the abnormality diversion order field are used by S600 to construct the current cycle state.

[0098] In one engineering embodiment, a batch of peelable eggs enters the peeling and separation unit from S400. The peelable egg flow record shows that this batch has a longer reheating time, more uniform distribution of cracked shells, moderate crack strength, and sparse crack density. The flexible shelling station first introduces the eggs one by one according to the batch release order, lifts the loose shell pieces by the flipping and separating part, and then gradually expands the cracked area circumferentially by the squeezing and shelling part. Subsequently, the shell and meat separation station removes the loosened shell pieces and separates the shell fragments from the egg conveying path by the broken shell screening part. Afterward, the integrity detection station performs surface inspection and contour recognition on each egg. Some eggs are identified as clean shells and enter the clean shell output channel, while others are identified as uncleaned eggs due to local shell residue. A small number of eggs are identified as stuck-shell eggs due to shell membrane adhesion, and a few eggs are identified as broken eggs due to local cracks. The sorting execution unit guides different eggs into the corresponding channels according to the above judgment results, and simultaneously sends the clean-shell egg flow record and abnormal egg flow record of this batch to the collaborative correction unit in S600.

[0099] The technical effect of this step can be summarized as follows: S500 transforms the peelable egg stream formed in S400 into a clean-shell egg stream and an abnormal egg stream, ensuring continuous correspondence between cracked shell state, peeling action, and detection results within the same batch link. S500 integrates flexible shell removal, broken shell removal, integrity detection, and anomaly classification into a unified processing procedure, enabling subsequent collaborative correction units to directly read the clean-shell output and anomaly diversion results. The record fields output by S500 are directly linked to the clean-shell rate, breakage rate, blockage status, and reflow reprocessing in S600.

[0100] S600. Based on the clean egg flow and abnormal egg flow, perform cycle time construction, buffer queue scheduling, multi-parameter linkage correction and differentiated backflow reprocessing to obtain the overall line collaborative control result.

[0101] The S600 receives the cleaned egg stream, the abnormal egg stream, the cleaned egg stream record, and the abnormal egg stream record output by the S500, and is continuously executed by the collaborative correction unit in the diversion and convergence section, the buffer queue scheduling section, and the parameter write-back section. Specifically, when receiving the current batch of data, the collaborative correction unit first reads the batch identifier field, cleaned egg quantity field, cleaned egg output order field, and station passage time field from the cleaned egg stream record, then reads the batch identifier field, abnormal type field, abnormal quantity field, abnormal diversion order field, and abnormal destination field from the abnormal egg stream record, and retrieves the buffer queue occupancy status field, the low-temperature quick-freezing unit load field, the rewarming and shell-cracking unit load field, the shell-peeling and separation unit load field, and the current batch associated record from the S100. The collaborative correction unit performs batch merging, time alignment, and status verification on the aforementioned fields. Batch merging combines clean-shell egg streams and abnormal egg streams under the same batch identifier into a single running object. Time alignment unifies the clean-shell output period and the abnormal flow distribution period. Status verification checks whether the current batch record matches the current equipment operating status. When batch merging, time alignment, and status verification pass, the cycle time construction and correction process for the current batch is initiated. When any verification fails, the collaborative correction unit maintains the current batch record in a pending correction state and rereads the entry cache segment and workstation status. It continues running after the data is complete.

[0102] Specifically, the collaborative correction unit first constructs the current cycle state by combining the buffer queue occupancy status field. The current cycle state represents the operating status of the current batch in the entire production line, including the occupancy status of the inbound buffer section, the occupancy status of the buffer section before the low-temperature quick-freezing unit, the occupancy status of the buffer section before the rewarming and shell-cracking unit, the passing order of the shell-cleaning output channel, the passing order of the abnormal diversion channel, and the waiting gaps between each workstation. The collaborative correction unit calculates the shell-cleaning rate and the breakage rate based on the shell-cleaning quantity field and the abnormal quantity field, wherein the shell-cleaning rate is determined based on the shell-cleaning quantity field and the total output quantity of the current batch, and the breakage rate is determined based on the number of broken egg streams corresponding to the abnormality type field; the line blockage status is jointly determined by the buffer queue occupancy status field, the shell-cleaning output order field, and the abnormal diversion order field. When any buffer section is continuously full, the shell-cleaning output order is stagnant, or the abnormal diversion order is accumulated, it is identified as a line blockage status; the equipment load is jointly represented by the load field of the low-temperature quick-freezing unit, the load field of the rewarming and shell-cracking unit, and the load field of the shell-peeling and separation unit. Understandably, the net shell ratio, the breakage rate, the line blockage status, the equipment load, and the current cycle time status constitute the minimum input set for this step, and the aforementioned contents directly participate in subsequent cache queue scheduling, parameter correction, and backflow reprocessing.

[0103] Furthermore, the buffer queue scheduling is a process of rearranging the passage relationship between preceding and following workstations based on the current cycle time state. The collaborative correction unit first determines the occupancy level of the abnormal egg flow channel and the throughput level of the shell-cleaning output channel. When the abnormal diversion sequence field shows continuous accumulation of abnormal egg flow, it prioritizes reducing the entry cycle time of the subsequent supplementary shell-cracking channel and secondary shell-peeling channel for the current batch, and places the independent diversion channel and secondary reheating channel in the preceding release position. When the shell-cleaning output sequence field shows that the throughput of the shell-cleaning output channel is slowing down, it prioritizes compressing the front-end feeding cycle time and widening the batch interval of the buffer section before the subsequent reheating shell-cracking unit. When the buffer section before the low-temperature quick-freezing unit is heavily occupied while the buffer section before the reheating shell-cracking unit is idle, it increases the release priority of the next batch's outgoing sequence. When the buffer section before the reheating shell-cracking unit and the entrance section of the shell-peeling separation unit are congested simultaneously, it adjusts the tray allocation order and outgoing sequence of the next batch to be placed later. After the buffer queue scheduling is completed, the cycle time correction result of the current batch is formed and bound to the current batch's associated record for subsequent parameter write-back.

[0104] Furthermore, the parameter correction is a process of adjusting the washing dwell time, draining dwell time, freezing zone dwell time, uniform temperature zone dwell time, warming dwell time, shell cracking strength, conveying interval, shell peeling line speed and abnormal egg flow distribution sequence in conjunction with the cycle correction results. Specifically, when the shell-cleaning rate decreases and the number of unshelled eggs in the abnormality type field increases, the collaborative correction unit increases the warming dwell time for the next batch and simultaneously decreases the peeling line speed; when the breakage rate increases and the number of broken eggs in the abnormality type field increases, the collaborative correction unit decreases the cracking intensity and shortens either the freezing zone dwell time or the isothermal zone dwell time; when the line blockage occurs in the buffer section before the low-temperature quick-freezing unit, the collaborative correction unit lengthens the connection interval between the washing dwell time and the draining dwell time and postpones the next batch tray allocation order; when the line blockage occurs at the entrance of the warming cracking unit or the peeling separation unit, the collaborative correction unit increases the conveying interval and decreases the peeling line speed; when the number of eggs with insufficient cracking in the abnormality type field increases, the collaborative correction unit advances the allocation order of abnormal eggs that supplement the cracking channel and increases the cracking effect density in the corresponding area of ​​the cracking location distribution in the next batch parameters. After the parameters are corrected, the next batch of parameter packages is formed. The next batch of parameter packages includes pretreatment parameters, tray allocation order, discharge order, rewarming time, shell crack location distribution, shell crack intensity, peeling linear speed, and abnormal egg flow allocation order.

[0105] Specifically, the reflux processing is a differentiated reflux process performed on different abnormal egg flows based on the abnormal destination field. The collaborative correction unit, according to the abnormality type field and the abnormal destination field, keeps broken egg flows in independent diversion channels, sends stuck-shell egg flows into a secondary warming channel, sends unpeeled egg flows into a secondary peeling channel, and sends insufficiently cracked egg flows into a supplementary cracking channel, writing the corresponding batch identifier and reflux order at the reflux inlet. For stuck-shell egg flows entering the secondary warming channel, the collaborative correction unit writes back a correction value for the warming dwell time; for unpeeled egg flows entering the secondary peeling channel, the collaborative correction unit writes back a correction value for the peeling line speed; for insufficiently cracked egg flows entering the supplementary cracking channel, the collaborative correction unit writes back a correction value for the crack strength and an abnormal egg flow allocation order. After the reflow reprocessing is completed, the collaborative correction unit generates the overall line collaborative control result. This result includes the preprocessing parameters, tray allocation order, discharge order, rewarming dwell time, shell crack location distribution, shell crack intensity, peeling line speed, and abnormal egg flow distribution order for the next batch, forming an associated record. This associated record, after being written with batch identifier, correction source, correction time, and correction content fields, is input to the preprocessing judgment unit, low-temperature quick-freezing unit, rewarming shell cracking unit, and peeling separation unit, respectively. Specifically, the preprocessing parameters are invoked at step S200, the tray allocation order and discharge order at step S300, the rewarming dwell time, shell crack location distribution, and shell crack intensity at step S400, and the peeling line speed and abnormal egg flow distribution order at step S500 for subsequent batches, thus forming a continuous closed loop across the main steps.

[0106] In one engineering embodiment, after a batch completes S500, the cleaned egg flow record shows a decrease in the number of cleaned eggs, the abnormal egg flow record shows a simultaneous increase in the flow of uncleaned eggs and the flow of eggs with insufficient cracked shells, and the buffer queue occupancy status field in S100 shows congestion in the buffer segment before the warming and cracking unit, and the load field of the shelling and separation unit is at a high level. The collaborative correction unit first merges the clean shell quantity field and the abnormal quantity field of the current batch, calculates that the clean shell rate of the current batch is low and the breakage rate is normal, and then determines that the current blockage occurs between the reheating and cracking unit and the shelling separation unit based on the clean shell output sequence field and the abnormal diversion sequence field. Subsequently, it performs parameter correction for the next batch, increasing the reheating dwell time, increasing the cracking intensity, increasing the conveying interval, and decreasing the shelling line speed, and placing the supplementary cracking channel corresponding to the insufficient cracked egg flow at the front of the abnormal egg flow allocation sequence. Afterwards, the resulting preprocessing parameters, tray allocation sequence, discharge sequence, reheating dwell time, cracking location distribution, cracking intensity, shelling line speed, and abnormal egg flow allocation sequence are written into the associated record and sent back to the corresponding workstations S200, S300, S400, and S500 for recall. The shell-sticky egg flow of the current batch enters the secondary reheating channel, the uncleaned egg flow enters the secondary shelling channel, the insufficient cracked egg flow enters the supplementary cracking channel, and the independent diversion channel keeps the broken egg flow output separately.

[0107] The technical effect of this step can be summarized as follows: S600 converts the cleaned egg flow and the abnormal egg flow into a rewritable overall line collaborative control result, establishing a continuous correlation between cleaned output, abnormal flow diversion, and front-end parameters. S600 places buffer queue scheduling, parameter correction, and reflow processing within the same batch processing link, ensuring the overall line operating status corresponds to the process parameters of the next batch. The correlation records formed by S600 are input into S200, S300, S400, and S500 respectively, enabling the invention to achieve cross-process linkage operation.

[0108] Example 2: Figure 2 This diagram illustrates a structural block diagram of a collaborative production control system for a batch quail egg low-temperature quick-freezing and shelling process according to an embodiment of the present invention. Figure 2 As shown, the structure may include:

[0109] The batch input set generation module 01 is used to collect batch information, initial temperature, surface condition, and equipment operating status of the quail eggs to be processed. It performs time alignment, field mapping, and unified encoding on the collected results to generate a batch input set. Specifically, the batch input set generation module receives the batch information, initial temperature, and surface condition of the quail eggs to be processed at the line entry position, and simultaneously receives the equipment operating status consisting of the load of the low-temperature quick-freezing unit, the load of the rewarming and shell-cracking unit, the load of the shell-peeling and separation unit, the occupancy status of the buffer queue, and the occupancy status of the abnormal egg flow channel. The batch information corresponds to the batch identifier, line entry time, and batch size; the initial temperature corresponds to the egg surface temperature and line entry temperature; and the surface condition corresponds to the shell moisture content, the state of adhering residue, and the state of surface integrity. The batch input set generation module performs time alignment on the aforementioned content under the same batch identifier, merging batch information, initial temperature, surface condition, and equipment operating status into the same acquisition window. Then, it performs field mapping, organizing the acquired content into batch identifier fields, line entry time fields, batch size fields, egg surface temperature fields, line entry temperature fields, shell moisture content fields, attachment residue status fields, surface integrity status fields, low-temperature quick-freezing unit load fields, rewarming and shell-cracking unit load fields, shell-peeling and separation unit load fields, buffer queue occupancy status fields, and abnormal egg flow channel occupancy status fields. All of these fields are uniformly encoded. When fields are missing, time is misaligned, or batch identifiers conflict, the batch input set generation module keeps the current batch record in a pending completion state until the corresponding acquired content is completed. The batch input set generation module outputs the batch input set and passes it to the preprocessing judgment module for invocation, while retaining the current batch record associated with the batch identifier field for the rewarming and shell-cracking module and the collaborative correction module to read.

[0110] The pretreatment determination module 02, connected to the batch input set generation module, is used to receive the batch input set, determine the cleaning pretreatment conditions and draining conditions according to the shell moisture content, adhesion residue status, surface integrity status and the equipment operating status, and generate a quick-freezing preparation instruction containing batch identifier, pretreatment parameters, feeding sequence and corresponding relationship with the carrier tray; specifically, the pretreatment determination module receives the shell moisture content field, adhesion residue status field, surface integrity status field and the corresponding field of the equipment operating status from the batch input set, and calls the batch identifier field, line entry time field and batch size field to confirm the affiliation of the current batch. The pre-treatment judgment module determines the cleaning spray intensity and draining residence time based on the shell's water content, the cleaning residence time based on the state of adhering residue, the feeding interval based on the surface integrity, and the tray allocation order based on the load field of the low-temperature quick-freezing unit and the buffer queue occupancy status field. The pre-treatment parameters correspond to the cleaning spray intensity, cleaning residence time, and draining residence time; the feeding sequence corresponds to the order in which the current batch enters the low-temperature quick-freezing unit and the conveying cycle time; and the tray correspondence corresponds to the association between the current batch and the position of an idle tray. When the equipment operating status update is delayed or there is a tray position conflict, the pre-treatment judgment module freezes the feeding write action for the current batch, while maintaining the association between the original batch identifier and the current judgment content. The pre-treatment judgment module outputs a quick-freezing preparation instruction, transmitting the batch identifier, pre-treatment parameters, feeding sequence, and tray correspondence to the low-temperature quick-freezing module for invocation, and retains the current judgment content in the current batch record for the collaborative correction module to write back the correction value.

[0111] The low-temperature quick-freezing module 03, connected to the pre-processing judgment module, receives the pre-freezing preparation instructions, performs layered loading according to the tray correspondence, controls the dwell time in the freezing zone, the dwell time in the uniform temperature zone, the tray spacing, and the loading sequence according to the batch identifier, and generates the target frozen and swollen egg product based on the loading sequence matching result. Specifically, the low-temperature quick-freezing module receives the batch identifier, pre-processing parameters, loading sequence, and tray correspondence from the pre-freezing preparation instructions, and imports the current batch into the corresponding tray and layer according to the tray correspondence, completing the layered loading of the same batch of eggs. The low-temperature quick-freezing module controls the dwell time in the freezing zone according to the batch identifier, and controls the dwell time in the uniform temperature zone according to the same batch identifier, and adjusts the tray spacing and loading sequence based on the release status of the front and rear trays, so that the current batch forms a continuous batch path in the freezing zone, uniform temperature zone, and loading port. During the loading stage, the low-temperature quick-freezing module records the shell surface hardening status, batch dwell status, and loading sequence, and associates the aforementioned content with the batch identifier and writes it into the current batch record. When there is a conflict in the loading tray, a queue in the freezing zone, or a delay in the release from the outlet, the low-temperature quick-freezing module keeps the current batch in the corresponding section waiting position and incorporates the waiting position information into the batch dwell state. The low-temperature quick-freezing module outputs the target frozen and heaved state of the eggs and transmits the shell surface hardening state, batch dwell state, and release sequence along with the target frozen and heaved state of the eggs to the rewarming and shell-cracking module for invocation.

[0112] The rewarming and shell-cracking module 04, connected to the low-temperature quick-freezing module, is used to receive the target frozen-swelled eggs. Based on the initial temperature and surface condition in the batch input set, the shell surface hardening state of the target frozen-swelled eggs, and the load of the rewarming and shell-cracking unit and the shell-peeling separation unit in the equipment's operating state, it determines the shell membrane separation requirement. Based on the shell membrane separation requirement, it performs rewarming buffering and directional shell cracking to generate a flow of peelable eggs. Specifically, the rewarming and shell-cracking module receives the target frozen-swelled eggs and their corresponding batch identifier, shell surface hardening state, batch dwell state, and outgoing sequence. Simultaneously, it retrieves the initial temperature and surface condition from the batch input set and reads the load of the rewarming and shell-cracking unit and the load of the shell-peeling separation unit. The warming and shell-cracking module determines the shell-membrane separation requirements based on the current batch's shell surface hardening state, initial temperature, surface condition, and subsequent workstation load. These requirements correspond to the warming dwell time, crack location distribution, crack intensity, and crack density. Subsequently, eggs in the target frozen-bulge state are guided into the warming buffer path according to the outgoing sequence. Warming buffering is performed according to the warming dwell time, conveying interval, and batch release order. Then, directional shell cracking is performed according to the crack location distribution, crack intensity, and crack density. When the warming buffer path is congested, the cracking cycle is mismatched, or the batch release order conflicts, the warming and shell-cracking module retains the current batch in the buffer position and updates the corresponding conveying interval and batch release order. The warming and shell-cracking module outputs a flow of peelable eggs and transmits the warming dwell time, conveying interval, batch release order, crack location distribution, crack intensity, and crack density to the shell-peeling separation module for recall. Simultaneously, the current shell-membrane separation requirements are retained in the current batch record for use by the collaborative correction module.

[0113] The shell-peeling separation module 05, connected to the reheating and shell-cracking module, receives the peelable egg stream and sequentially performs flexible shell removal, broken shell removal, integrity detection, and anomaly classification to generate clean-shell egg streams and abnormal egg streams. Specifically, the shell-peeling separation module receives the peelable egg stream along with the reheating dwell time, conveying interval, batch release order, crack location distribution, crack intensity, and crack density corresponding to the current batch. It first organizes the current batch into the flexible shell removal path according to the batch release order and conveying interval, and then performs flipping and squeezing shell removal based on the crack location distribution, crack intensity, and crack density. After completing the flexible shell removal, the shell-peeling separation module performs shell fragment extraction and broken shell screening, and performs residual shell identification, damage identification, and clean-shell identification on the shell-peeled eggs. Eggs identified as abnormal are classified into broken egg streams, stuck-shell egg streams, incompletely clean-shell egg streams, and insufficiently cracked egg streams, and a corresponding relationship is formed between independent diversion channels, secondary reheating channels, secondary shell-peeling channels, and supplementary crack-cracking channels according to the abnormal destination. When the inlet cycle mismatch, shell extraction obstruction, or abnormal diversion congestion occurs, the shelling separation module updates the cleaned shell output order and abnormal diversion order of the current batch. The shelling separation module outputs the cleaned shell egg flow and the abnormal egg flow, and transmits the cleaned shell quantity, cleaned shell output order, station passage time, abnormal type, abnormal quantity, abnormal diversion order, and abnormal destination to the collaborative correction module for invocation.

[0114] The collaborative correction module 06 is connected to the preprocessing judgment module, the low-temperature quick-freezing module, the rewarming and shell-cracking module, and the shell-peeling and separation module, respectively. It is used to receive the clean-shell egg flow and the abnormal egg flow, construct the current cycle state by combining the buffer queue occupancy status, and perform buffer queue scheduling, parameter correction and reflow reprocessing based on the clean shell rate, breakage rate, line blockage status, equipment load and the current cycle state. It generates a line-wide collaborative control result containing the preprocessing parameters of the next batch, the tray allocation order, the outbound order, the rewarming dwell time, the shell-cracking location distribution, the shell-cracking intensity, the shell-peeling line speed and the abnormal egg flow allocation order, and forms an associated record to input into the preprocessing judgment module, the low-temperature quick-freezing module, the rewarming and shell-cracking module and the shell-peeling and separation module. Specifically, the collaborative correction module receives the cleaned egg stream, abnormal egg stream, cleaned egg quantity, cleaned egg output order, station passage time, abnormality type, abnormality quantity, abnormality diversion order, and abnormality destination from the shelling and separation module. It then calls upon the buffer queue occupancy status and current equipment operating status from the batch input set to construct the current cycle time status. Subsequently, it forms the cleaned egg rate and breakage rate based on the cleaned egg quantity and abnormality quantity, forms the line congestion status based on the buffer queue occupancy status, cleaned egg output order, and abnormality diversion order, and forms the equipment load based on the load of the low-temperature quick-freezing unit, the load of the rewarming and cracking unit, and the load of the shelling and separation unit. Based on the aforementioned content, the collaborative correction module performs buffer queue scheduling, rearranges the passage order of the current batch and the next batch at each buffer position and abnormality destination, and then corrects the preprocessing parameters, tray allocation order, outbound order, rewarming dwell time, crack location distribution, crack intensity, shelling line speed, and abnormal egg stream allocation order based on the abnormality type and current cycle time status. Simultaneously, it performs reflow processing on the abnormal egg stream and writes back the corresponding batch identifier and reflow order. The collaborative correction module outputs the overall line collaborative control results, forms an associated record, and inputs it into the pre-processing judgment module, the low-temperature quick-freezing module, the rewarming and shell-cracking module, and the shell-peeling and separation module respectively. The pre-processing parameters are called by the pre-processing judgment module, the tray allocation order and the outgoing order are called by the low-temperature quick-freezing module, the rewarming dwell time, the distribution of shell-cracking locations, and the intensity of shell-cracking are called by the rewarming and shell-cracking module, and the shell-peeling line speed and the abnormal egg flow allocation order are called by the shell-peeling and separation module. The correction content, correction time, and correction source are written into the current batch record.
