Description

Technical Field

[0001] This invention relates to the field of liquor production technology, and in particular to a raw material processing system and method for the production of multi-grain aroma liquor. Background Technology

[0002] In the production of baijiu (Chinese liquor), different brewing raw materials such as sorghum, wheat, corn, rice, and glutinous rice usually need to undergo pretreatment such as crushing, mixing, adding water, and moistening before entering the steaming, mixing, or subsequent fermentation preparation processes.

[0003] In existing raw material processing methods, different wetting times, water addition amounts, or processing sequences can be set according to the water absorption properties of different brewing raw materials to reduce the impact of differences in water absorption characteristics on subsequent production. However, in actual production, the initial moisture content, particle size, and water absorption rate of different batches of raw materials fluctuate. Even with a preset wetting time, the actual time when various raw materials reach the appropriate processing state may still vary significantly. When raw materials with faster water absorption reach the predetermined wetting state first, it is usually necessary to stop adding water and wait for other raw materials with slower water absorption to complete processing. However, after the active wetting of brewing raw materials stops, there is still a process of moisture migration and redistribution between their surface and interior, causing the actual wetting state of the raw materials to continue to change during the waiting period. Especially when multiple brewing raw materials need to be combined at the same time according to the proportion corresponding to the current baijiu aroma type, a delay in the processing progress of one raw material will prolong the waiting time of other processed raw materials and further alter the degree of state migration after wetting stops. The existing method, which uses fixed wetting times and independently judges whether each raw material has reached the target state, makes it difficult to synchronously adjust the wetting termination conditions of other raw materials according to changes in the processing progress of one raw material. This easily leads to the problem that while various raw materials meet the requirements when processed individually, some raw materials have deviated from their suitable processing state when they enter subsequent processes together. This affects the consistency of raw material processing states and the stability of subsequent brewing processes in the production of multi-grain aroma baijiu. In addition, the raw material combinations, raw material ratios, and the required wetting states of various raw materials when entering subsequent processes differ for different baijiu aroma types. Using a uniform target state makes it difficult to meet the switching needs of multi-grain aroma production.

[0004] Therefore, a raw material processing system and method for the production of multi-grain aroma-type baijiu is needed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a raw material processing system and method for the production of multi-grain-flavored baijiu.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A raw material processing system and method for the production of multi-grain aroma baijiu, comprising:

[0008] The raw material sorting and processing unit is used to receive different types of brewing raw materials separately and to perform active moistening treatments, including adding water and turning, on each type of brewing raw material.

[0009] The aroma type target determination unit is used to determine the target processing state of each type of brewing raw material when it enters the subsequent mixing process, based on the aroma type of the liquor to be produced and the types of brewing raw materials involved in the production.

[0010] The raw material status acquisition unit is used to acquire the current processing status of various brewing raw materials during the active wetting process, and to determine the status changes of various brewing raw materials based on the continuously acquired current processing status.

[0011] The convergence time determination unit is used to determine the common convergence time when various brewing raw materials enter the subsequent mixing process based on the current processing status of various brewing raw materials, the predicted remaining processing time required to reach the corresponding target processing status, and the feeding requirements of the subsequent mixing process.

[0012] The state migration prediction unit is used to predict the amount of state migration of each type of brewing raw material due to the continued migration of internal moisture during the interval time from the cessation of active wetting to the common convergence time, based on the processing state of the raw material when active wetting is stopped.

[0013] The collaborative control unit is used to determine the early stop state corresponding to the cessation of active wetting of various brewing raw materials based on the target processing state and the corresponding state transition amount at the common convergence time of various brewing raw materials, and to stop the active wetting of the corresponding brewing raw materials when the early stop state is reached.

[0014] Specifically, when the expected completion time of any type of brewing raw material is delayed and deviates from the preset coordination range, the collaborative control unit re-determines the common convergence time based on the updated expected completion time of that type of brewing raw material, and re-determines the state migration amount corresponding to the other types of brewing raw materials based on the updated common convergence time; for the other brewing raw materials that are still in the active lubrication stage, their early stop state is re-determined; for the other brewing raw materials that have entered the waiting stage, their processing state at the updated common convergence time is re-predicted. When the predicted processing state is within the allowable deviation range of the corresponding target processing state, the waiting is maintained; when it exceeds the allowable deviation range, the brewing raw material of that type is isolated from the convergence batching unit, the batching of this batch is suspended, and an abnormal state is output.

[0015] The batching and mixing unit is used to batch and mix various brewing raw materials according to the raw material ratio corresponding to the aroma type of the liquor to be produced after the various brewing raw materials have undergone waiting stages corresponding to the common batching time after the active moistening has stopped.

[0016] By adopting the above technical solution, a closed loop is formed by actively lubricating different raw materials separately, determining the target state, acquiring the real-time state, determining the time of convergence, predicting the state migration after stopping, calculating the state of early stopping in advance, and forming a convergence batch. This changes the control endpoint of various raw materials from "achieving the standard when each material stops" to "achieving the standard when entering the subsequent process together". When the expected completion time of any raw material is delayed and deviates from the preset coordination range, the time of convergence can be re-determined and the state migration amount and processing status of other raw materials can be adjusted in conjunction, thereby reducing the state deviation caused by the raw materials that have completed first continuing to absorb water during the waiting period.

[0017] Preferably, the raw material state acquisition unit is used to acquire at least the current moisture content of various brewing raw materials, and further acquire at least one of the following: raw material temperature, active wetting duration, and state change per unit time.

[0018] The actual rate of change of the state of the corresponding brewing raw materials is determined based on the current moisture content obtained within a continuous period, or based on the current processing state characterized by the current moisture content and other state parameters.

[0019] By adopting the above technical solution, the moisture content, temperature and state change rate of the actual batch of raw materials can be used as the control basis, and the batch differences caused by the different initial moisture content, particle state and water absorption capacity of the same raw materials can be reflected in a timely manner. This provides a continuous data basis for predicting the remaining processing time, state migration amount and stopping time, and avoids control deviation caused by relying solely on fixed wetting time.

[0020] Preferably, the aroma target determination unit stores the correspondence between the aroma type of baijiu, the type of brewing raw materials, and the target processing state;

[0021] After determining the aroma type of the liquor to be produced, the corresponding target processing state is determined according to the various brewing raw materials involved in the production of that aroma type of liquor;

[0022] The target processing state includes at least one of the target moisture content and the target wettability uniformity.

[0023] By adopting the above technical solution, corresponding target states can be called for different baijiu aroma types and their raw material combinations, so that the same processing system does not need to use a single lubrication endpoint when switching aroma types. Instead, corresponding control targets are set for different raw materials according to the current aroma type, thereby improving the adaptability when switching between multiple grain aroma types.

[0024] Preferably, the convergence time determination unit determines the predicted remaining processing time required for each type of brewing raw material to reach the corresponding processing requirements under the current active moistening conditions, based on the current processing status and status changes of each type of brewing raw material.

[0025] The common convergence time is determined based on the predicted remaining processing time and the allowable feeding time for subsequent mixing processes, so that each type of brewing raw material has a state transition time from the cessation of active wetting to the common convergence time.

[0026] By adopting the above technical solution, the predicted remaining processing time of each raw material and the allowable feeding time of the subsequent mixing process are used together to determine the common convergence time. A unified time benchmark can be established among the raw materials, and the waiting time after the active lubrication of each type of raw material is stopped can be clearly defined, providing a time boundary for subsequent calculation of state transition and early stop state.

[0027] Preferably, the state transition prediction unit determines the predicted state change trend of the corresponding brewing raw material during the waiting stage based on the current moisture content before the active wetting of the raw material stops, the actual state change rate, the raw material temperature, and the interval between the cessation of active wetting and the moment of convergence.

[0028] Based on the predicted state change trend, the state migration amount of this type of brewing raw material from the processing state when active moistening stops to the moment of common convergence is determined.

[0029] By adopting the above technical solution, the process of surface moisture diffusion into the interior and moisture redistribution that continues to occur after the addition of water to the raw materials can be controlled, rather than assuming that the state is immediately fixed after the active lubrication is stopped, thereby improving the accuracy of predicting the actual state at the moment of convergence.

[0030] Preferably, the collaborative control unit takes the target processing state that the corresponding brewing raw materials should reach at the moment of common convergence as the final control target, and determines the early stopping state of the corresponding brewing raw materials in reverse according to the state transition amount;

[0031] The state difference between the early stop state and the target processing state is maintained, corresponding to the state migration amount, so that after the corresponding brewing raw material stops active moistening, it approaches the target processing state by migrating internal moisture during the waiting period.

[0032] By adopting the above technical solution, the early stopping state is determined by reverse direction with the target processing state at the moment of convergence as the endpoint, so that the raw materials can complete the remaining state changes by utilizing the natural moisture migration during the waiting period, reducing the possibility of excessive water absorption or state deviation caused by continuing to wait after reaching the target first.

[0033] Preferably, the collaborative control unit is used to determine the corresponding predicted state change rate based on the current processing state, target processing state, and predicted remaining processing time of various brewing raw materials, and compare the actual state change rate of various brewing raw materials with the predicted state change rate.

[0034] When the deviation between the actual rate of change of any type of brewing raw material and the corresponding predicted rate of change of state exceeds a preset deviation range, the predicted remaining processing time of that type of brewing raw material is re-determined, and it is determined whether its expected completion time deviates from the preset coordination range.

[0035] By adopting the above technical solution, the remaining processing time and expected completion time can be updated in a timely manner when the actual rate of change deviates from the predicted value, so that the system can adapt to the fluctuation of water absorption rate of different batches of raw materials and prevent early prediction errors from being continuously transmitted to the confluence stage.

[0036] Preferably, when the expected completion time of any type of brewing raw material is delayed and causes the common convergence time to be updated, the collaborative control unit re-determines the waiting time for the other types of brewing raw materials from the cessation of active wetting to the common convergence time based on the updated common convergence time;

[0037] The state migration amount of the remaining brewing raw materials is re-predicted based on the re-determined waiting time. For the remaining brewing raw materials that are still in the active lubrication stage, the early stop state is re-determined based on the re-predicted state migration amount. For the remaining brewing raw materials that have entered the waiting stage, their processing state at the updated common convergence time is re-predicted based on the remaining waiting time. When the predicted processing state is within the allowable deviation range of the corresponding target processing state, the waiting continues. When it exceeds the allowable deviation range, the brewing raw material of this type is kept isolated from the convergence and batching unit, the batching and batching of this batch is suspended, and an abnormal state is output, so that the processing progress of one type of brewing raw material is linked to the adjustment of the processing state of other brewing raw materials.

[0038] By adopting the above technical solution, the processing delay of a single raw material no longer only affects the raw material itself, but can trigger the linkage adjustment of the common convergence time and the waiting time, migration amount and processing status of other raw materials, thereby reducing the chain deviation caused by the mismatch of processing progress among multiple raw materials.

[0039] Preferably, a waiting and holding unit corresponding to each type of brewing raw material is provided between the raw material diversion processing unit and the batching and mixing unit;

[0040] The waiting and holding unit is used to independently and temporarily store the corresponding brewing raw materials after they reach the early stop state and the active moistening stops. This allows the brewing raw materials to be left to stand, agitated, or alternately left to stand and agitated while the water addition stops, so that the moisture between the surface and the interior of the raw materials can continue to migrate.

[0041] Once all the brewing raw materials involved in this batch of production meet the convergence conditions and reach the common convergence time, the batching unit will transport the brewing raw materials in each waiting holding unit to the same processing area corresponding to the aroma type of the liquor to be produced, according to the raw material ratio.

[0042] By adopting the above technical solution, different raw materials that have stopped actively moistening can be stored independently and temporarily. If necessary, static or low-intensity turning can be used to maintain the conditions for moisture migration. This can reduce the mutual influence caused by premature mixing of different raw materials, and then be transported in a centralized manner according to the current aroma ratio when they are combined.

[0043] A method for processing raw materials for the production of multi-grain aroma baijiu includes the following steps:

[0044] S1. Determine the aroma type of the liquor to be produced and the types of brewing raw materials involved in the production, and determine the target processing state of each type of brewing raw material when it enters the subsequent mixing process according to the aroma type of the liquor and the types of brewing raw materials.

[0045] S2. Different types of brewing raw materials are sent to their respective processing areas for active moistening, including adding water and turning. During the active moistening process, the current processing status of each type of brewing raw material is continuously acquired, and the status changes of each type of brewing raw material are determined based on the continuously acquired current processing status.

[0046] S3. Based on the current processing status and status changes of various brewing raw materials, determine the predicted remaining processing time required to reach the corresponding processing requirements, and combine the feeding requirements of the subsequent mixing process to determine the common convergence time of various brewing raw materials entering the subsequent mixing process.

[0047] S4. For each type of brewing raw material, based on the processing state of the raw material when active wetting stops and the interval between the cessation of active wetting and the moment of convergence, predict the amount of state migration of the raw material due to the continued migration of internal moisture after the cessation of active wetting.

[0048] S5. Based on the target processing state and the corresponding state transition amount corresponding to the common convergence of various brewing raw materials, determine the early stop state corresponding to the cessation of active moistening of various brewing raw materials from the target processing state.

[0049] S6. Actively moisten each type of brewing raw material. When any type of brewing raw material reaches the corresponding early stop state, stop the active moistening of that type of brewing raw material and put it into a waiting stage, so as to utilize the internal moisture migration during the waiting stage to change its processing state to the corresponding target processing state.

[0050] S7. During the active lubrication process, continuously update the predicted remaining processing time of various brewing raw materials. When the expected completion time of any type of brewing raw material is delayed and deviates from the preset coordination range, re-determine the common convergence time based on the updated expected completion time of that type of brewing raw material.

[0051] S8. Based on the newly determined common convergence time, redetermine the waiting time between the cessation of active moistening and the common convergence time for the remaining types of brewing raw materials, and re-predict the state migration amount of the remaining types of brewing raw materials based on the newly determined waiting time; for the remaining brewing raw materials that are still in the active moistening stage, redetermine the corresponding early stop state based on the re-predicted state migration amount; for the remaining brewing raw materials that have entered the waiting stage, re-predict their processing state at the updated common convergence time based on the remaining waiting time, and continue waiting when the predicted processing state is within the allowable deviation range of the corresponding target processing state; when it exceeds the allowable deviation range, keep the type of brewing raw material in an isolated state, do not participate in the current batch of batching, suspend the current batch of batching and output an abnormal state, so that the change in the processing progress of one type of brewing raw material will be linked to adjust the processing state of other brewing raw materials;

[0052] S9. After the active lubrication is stopped, each type of brewing raw material undergoes a corresponding waiting stage. When all types of brewing raw materials participating in this batch of production meet the convergence conditions and reach the common convergence time, the various types of brewing raw materials are converged according to the raw material ratio corresponding to the aroma type of the liquor to be produced, so that when the various types of brewing raw materials enter the subsequent process together, they are respectively within the allowable deviation range of the corresponding target processing state.

[0053] By adopting the above technical solution, and by establishing the target state, real-time state, common convergence time, migration amount after stopping, early stop state, and linkage recalculation relationship in the method flow, the raw material processing control is transformed from fixed-time control to dynamic collaborative control oriented to the common feeding state, which is conducive to improving the consistency of different raw material processing states in the production of multi-grain aroma baijiu.

[0054] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0055] 1. By actively moistening different brewing raw materials separately, and predicting the state migration amount of each raw material after stopping active moistening around the time of their common convergence, and then determining the early stopping state in reverse from the target processing state that should be achieved at the time of common convergence, the final goal of each raw material is not "meeting the standard when stopping processing", but "meeting the standard when entering the subsequent process together". This can reduce the problem of raw materials that are completed first deviating from the suitable state due to the continued migration of moisture during the waiting period. This is in contrast to the problem in the background technology where multiple raw materials are qualified when completed separately, but their states are inconsistent when they are fed together.

[0056] 2. The aroma target determination unit determines the target processing state according to the aroma of the liquor to be produced and the types of raw materials involved in the production. This allows the same processing system to call the corresponding lubrication control target for different aromas and different combinations of raw materials, without having to apply the same processing endpoint to different aromas. This improves the system's adaptability to switching between the production of multi-grain aroma liquors.

[0057] 3. The raw material state acquisition unit continuously acquires the current moisture content, temperature, active wetting duration, and state change amount, and determines the actual state change rate accordingly. The fluctuations in the initial moisture content, particle state, and batch water absorption capacity of the raw material can be fed back into the prediction of the remaining processing time, thereby reducing the error caused by insufficient adaptation of fixed wetting time to batch differences.

[0058] 4. The internal moisture diffusion and redistribution after the raw material stops being watered are included in the prediction by the state migration prediction unit. The co-control unit then sets an early stop state based on the predicted migration amount. The remaining state changes can be completed by utilizing the natural moisture migration that occurs during the waiting period, reducing the over-wetting or state drift caused by the raw material being wetted to the final target first and then waiting for a long time.

[0059] 5. When the expected completion time of any type of raw material is delayed and deviates from the preset coordination range, the waiting time, state transition amount and processing status of other raw materials are adjusted in conjunction with the re-determining of the common convergence time. This allows the abnormal delay of one raw material to be synchronously fed back to the termination control conditions of the remaining raw materials, avoiding a chain deviation where the delay of one raw material causes the waiting time of other raw materials to run out of control when each raw material is controlled independently. For raw materials that have entered the waiting stage and whose predicted processing status exceeds the allowable deviation range, by keeping them isolated from the convergence batching unit and suspending the convergence batching of this batch, it is possible to avoid continuing to converge and destroy the established raw material ratio when the necessary raw materials for the current flavor are missing.

[0060] 6. By using a waiting and holding unit to temporarily store various raw materials that have stopped being actively moistened, and maintaining them in a static, agitated, or alternating state as needed, they are then combined according to the corresponding ratio for the current aroma type when they reach the time of convergence. This helps to maintain the independent state control of different raw materials, reduce mutual interference caused by premature mixing, and improve the feeding stability and batch consistency of subsequent mixing, steaming, and fermentation preparation processes.

[0064] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0065] Reference Figure 1 and Figure 2 A raw material processing system for the production of multi-grain aroma baijiu, comprising:

[0066] The raw material sorting and processing unit is used to receive different types of brewing raw materials separately and to perform active moistening treatments, including adding water and turning, on each type of brewing raw material.

[0067] The aroma type target determination unit is used to determine the target processing state of each type of brewing raw material when it enters the subsequent mixing process, based on the aroma type of the liquor to be produced and the types of brewing raw materials involved in the production.

[0068] The raw material status acquisition unit is used to acquire the current processing status of various brewing raw materials during the active wetting process, and to determine the status changes of various brewing raw materials based on the continuously acquired current processing status.

[0069] The convergence time determination unit is used to determine the common convergence time when various brewing raw materials enter the subsequent mixing process based on the current processing status of various brewing raw materials, the predicted remaining processing time required to reach the corresponding target processing status, and the feeding requirements of the subsequent mixing process.

[0070] The state migration prediction unit is used to predict the amount of state migration of each type of brewing raw material due to the continued migration of internal moisture during the interval time from the cessation of active wetting to the common convergence time, based on the processing state of the raw material when active wetting is stopped.

[0071] The collaborative control unit is used to determine the early stop state corresponding to the cessation of active wetting of various brewing raw materials based on the target processing state and the corresponding state transition amount at the common convergence time of various brewing raw materials, and to stop the active wetting of the corresponding brewing raw materials when the early stop state is reached.

[0072] Specifically, when the expected completion time of any type of brewing raw material is delayed and deviates from the preset coordination range, the collaborative control unit re-determines the common convergence time based on the updated expected completion time of that type of brewing raw material, and re-determines the state migration amount corresponding to the other types of brewing raw materials based on the updated common convergence time; for the other brewing raw materials that are still in the active lubrication stage, their early stop state is re-determined; for the other brewing raw materials that have entered the waiting stage, their processing state at the updated common convergence time is re-predicted. When the predicted processing state is within the allowable deviation range of the corresponding target processing state, the waiting is maintained; when it exceeds the allowable deviation range, the brewing raw material of that type is isolated from the convergence batching unit, the batching of this batch is suspended, and an abnormal state is output.

[0073] The batching and mixing unit is used to batch and mix various brewing raw materials according to the raw material ratio corresponding to the aroma type of the liquor to be produced after various brewing raw materials have undergone waiting stages corresponding to the common batching time after the active moistening has stopped.

[0074] In this embodiment, the raw material distribution processing unit can be set up with two or more independent processing channels according to the types of raw materials involved in production. Each processing channel can be equipped with a raw material bin, a quantitative feeding component, a water addition component, a turning component, and a discharge control component. The water addition component can be a spray pipe, an atomizing nozzle, or an equivalent structure that can adjust the water supply according to control commands. The turning component can be a stirring paddle, a turning plate, or a slow turning mechanism. Different processing channels maintain material isolation during the active wetting stage, so that any two or more raw materials among sorghum, wheat, corn, rice, and glutinous rice can be wetting controlled separately, without requiring all raw materials to use the same water addition rhythm and stopping time. Active wetting, as referred to in this document, means the processing stage in which the raw materials absorb external moisture under controlled water addition and turning conditions. Stopping active wetting means stopping the addition of wetting water, but the existing moisture on the surface and inside of the raw materials can still continue to diffuse and redistribute.

[0075] Furthermore, refer to Figure 1 It can be understood that the raw material state acquisition unit is used to acquire at least the current moisture content of various brewing raw materials, and further acquire at least one of the following: raw material temperature, active wetting duration, and state change per unit time.

[0076] Based on the current moisture content obtained within a continuous period, or based on the current processing state characterized by the current moisture content and other state parameters, the actual rate of change of the corresponding brewing raw materials is determined.

[0077] Specifically, each processing channel can be equipped with an online moisture detection component for detecting the moisture content of the raw materials and a temperature detection component for detecting the temperature of the raw materials. For cases requiring evaluation of the wetting uniformity, multiple sampling locations can be set at different positions within the processing area. The maximum difference, average deviation, or dispersion of moisture content between different sampling locations characterizes the wetting uniformity. The control unit continuously records the current state value X_i(t) of the i-th type of raw material according to a set sampling period, and determines the actual state change rate v_i(t) of the raw material using the state difference between adjacent sampling times and the sampling time interval. The state value X_i(t) can be the moisture content, or a state quantity jointly characterized by moisture content, temperature, and wetting uniformity. Through continuous sampling, the actual water absorption process of the current batch of raw materials can be obtained, allowing subsequent predictions to be based on real-time conditions rather than solely relying on a preset fixed wetting duration.

[0078] Furthermore, refer to Figure 1 It can be seen that the aroma target determination unit stores the correspondence between the aroma type of baijiu, the type of brewing raw materials, and the target processing state;

[0079] After determining the aroma type of the liquor to be produced, the corresponding target processing state is determined according to the various brewing raw materials involved in the production of that aroma type of liquor;

[0080] The target processing state includes at least one of target moisture content and target wettability uniformity.

[0081] The correspondence between aroma type, raw material type, and target processing state can be pre-stored in a parameter table on the control terminal. This parameter table can be established based on the target states that have been adopted and verified in the production process. After switching the aroma type of the liquor to be produced, the control terminal first determines the types of raw materials involved in the production of this batch, and then reads the target moisture content and / or target wetting uniformity of each type of raw material when it enters the subsequent mixing process. For the same raw material, different target processing states can be corresponding to different liquor aroma types or different raw material ratios, enabling the system to perform corresponding control for the raw material combination of the current aroma type, rather than uniformly processing all aroma types according to the same wetting endpoint.

[0082] Furthermore, refer to Figure 1 It can be seen that the convergence time determination unit determines the predicted remaining processing time required for each type of brewing raw material to reach the corresponding processing requirements under the current active moistening conditions, based on the current processing status and status changes of each type of brewing raw material.

[0083] The common convergence time is determined based on the predicted remaining processing time and the allowable feeding time of subsequent mixing processes, so that each type of brewing raw material has a state transition time from the cessation of active wetting to the common convergence time.

[0084] When determining the common convergence time, the predicted remaining processing time for each raw material can be obtained first based on the state difference between its current processing state and the corresponding target processing state, as well as the recent rate of state change. For raw materials whose state continuously changes towards the target direction with active lubrication, the initial predicted remaining processing time can be determined based on the difference between the target processing state and the current processing state, as well as the recent rate of state change. If the rate of state change changes, the prediction results are updated based on the recent trend obtained from continuous sampling. Subsequently, the estimated completion time of each raw material is compared with the allowable feeding time of subsequent mixing processes. Under the condition of meeting the feeding requirements of subsequent processes, the time that can cover the processing progress of each raw material is determined as the common convergence time T_c. The common convergence time is not fixed after initial determination, but is continuously corrected according to the actual state changes of each raw material during subsequent active lubrication.

[0085] Furthermore, refer to Figure 1 It can be seen that the state transition prediction unit determines the predicted state change trend of the corresponding brewing raw material during the waiting stage based on the current moisture content before the active wetting of the raw material stops, the actual state change rate, the raw material temperature, and the interval between the cessation of active wetting and the moment of convergence.

[0086] And based on the predicted state change trend, determine the state migration amount of this type of brewing raw material from the processing state when active moistening stops to the moment of common convergence;

[0087] State migration is used to characterize the changes in processing state of raw materials after water addition stops, during the waiting period until the common convergence time, due to the continued diffusion of surface moisture into the grain interior and the redistribution of internal moisture. When moisture content is used as the control variable, the state migration of the i-th type of raw material can be expressed as ΔM_i = F_i(M_i, T_i, v_i, τ_i), where M_i is the moisture content of the raw material when active watering stops, T_i is the temperature of the raw material when active watering stops, v_i is the recent actual state change rate of the raw material before active watering stops, τ_i is the waiting time between the cessation of active watering and the common convergence time, and F_i is the state migration relationship of the corresponding raw material. The state migration relationship can be a lookup table correspondence established from previous processing data of the same type of raw material, a segmented correspondence, or an equivalent relationship corrected based on the state change rate and state changes during the waiting period of this batch. Its purpose is to determine the expected amount of state change that will continue to occur in this type of raw material within a specific waiting time.

[0088] In practical implementation, state transition relationship tables can be established for different raw material types. These tables should include at least the moisture content at the time of cessation of active wetting, raw material temperature, recent actual state change rate, and waiting time as input items, and the change in moisture content after the corresponding waiting time as the output item. The control terminal calls the corresponding state transition relationship based on the current raw material type and the aforementioned input items to obtain the state transition amount ΔM_i. When new valid state data is obtained during the actual waiting phase of this batch, the corresponding relationship used for subsequent predictions can be updated based on the new actual state change results.

[0089] When establishing the state transition relationship table, the moisture content, raw material temperature, recent actual state change rate, actual waiting time, and moisture content change after the waiting period can be collected from historical production batches according to the raw material type. Each input item is grouped according to a preset interval, and the average or median value of the moisture content change within the same input interval is used as the corresponding state transition amount. For the current input state between adjacent intervals, the corresponding state transition amount can be determined by adjacent data interpolation.

[0090] When the early stopping state is not yet determined, the control terminal can use a candidate state iteration method to determine the state transition amount and the early stopping state. Specifically, firstly, a candidate stopping state is determined based on the current processing state, the current actual state change rate, and the common convergence time. The candidate stopping time to reach this candidate stopping state is predicted based on the current actual state change rate, and the candidate waiting time is determined by the time difference between the common convergence time and the candidate stopping time. Then, the candidate stopping state, raw material temperature, recent actual state change rate, and candidate waiting time are input into the corresponding state transition relationship to obtain the candidate state transition amount. The candidate early stopping state is then re-determined based on the target processing state and the candidate state transition amount. When the difference between the re-determined candidate early stopping state and the previous candidate early stopping state is within a set convergence range, the current candidate early stopping state is taken as the early stopping state corresponding to this prediction cycle. If it is not within the convergence range, the above update process continues. Alternatively, multiple candidate stopping states can be preset, and the waiting time and state transition amount corresponding to each candidate stopping state can be calculated. The candidate stopping state that makes the sum of the candidate stopping state and the corresponding state transition amount fall within the allowable deviation range of the target processing state is selected as the early stopping state.

[0091] The initial candidate stopping state can be selected from the state value between the current processing state and the target processing state, or the early stopping state corresponding to the qualified production batch of the same brewing raw material in history can be used as the initial candidate stopping state. The set convergence range can be determined according to the measurement resolution of the detection component corresponding to the raw material state acquisition unit and the allowable deviation range of the target processing state. The corresponding state difference range is not greater than the allowable deviation range of the target processing state, so that the candidate early stopping state obtained after iterative stopping can meet the subsequent control accuracy requirements.

[0092] Furthermore, refer to Figure 1 It can be seen that the collaborative control unit takes the target processing state that the corresponding brewing raw materials should reach at the moment of common convergence as the final control target, and determines the early stopping state of the corresponding brewing raw materials in reverse according to the state transition amount;

[0093] The state difference between the early stop state and the target processing state is maintained, corresponding to the state migration amount, so that after the corresponding brewing raw material stops active moistening, it approaches the target processing state by utilizing the internal moisture migration during the waiting period.

[0094] For raw materials whose state continues to change towards the final target during the waiting phase, the early stop state can be obtained by subtracting the predicted state migration during the waiting phase from the target processing state at the time of convergence. Taking moisture content as an example, the early stop moisture content of the i-th type of raw material can be determined according to M_stop,i = M_target,i - ΔM_i, where M_target,i is the target moisture content that the raw material should reach at the time of convergence, and ΔM_i is the predicted moisture content migration during the waiting phase. Therefore, the raw material can stop adding water when it reaches M_stop,i. At this time, the raw material may not have reached the final target moisture content yet, and it can continue to migrate using internal moisture during the subsequent waiting phase, causing it to approach M_target,i at the time of convergence. If the target processing state includes both moisture content and uniform wetting state, corresponding early stop conditions can be set separately, and active wetting can be terminated when the corresponding termination conditions are met.

[0095] When the target processing state includes the target wetted material uniformity state, the maximum difference in moisture content between different sampling locations can be used as the uniformity state index U_i. The smaller the U_i, the more uniform the wetted material state of the corresponding brewing raw material. The rate of change of uniformity state can be determined based on the change in U_i and the sampling time interval within a continuous sampling period. The control terminal establishes the uniformity state migration relationship of the corresponding raw material based on the uniformity state index U_i when active wetted material stops, the raw material temperature, the rate of change of uniformity state before stopping active wetted material, and the waiting time between stopping active wetted material and the common convergence time, and predicts the uniformity state index at the common convergence time. The uniformity state migration relationship can be established using the same historical data grouping, table lookup, or adjacent interval interpolation method as the moisture content state migration relationship. When the predicted uniformity state index at the common convergence time is within the allowable deviation range corresponding to the target wetted material uniformity state, the corresponding raw material meets the early stopping condition of the wetted material uniformity state dimension.

[0096] For cases where uniform wetting is one of the target processing states, the aforementioned candidate stopping state iteration process also applies to the uniformity state index U_i. The control unit can input the uniformity state index at the candidate stopping time, the corresponding uniformity state change rate, and the candidate waiting time into the uniformity state migration relationship, and adjust the candidate stopping state in reverse according to the target uniform wetting state at the common merging time until the predicted uniformity state index at the common merging time is within the corresponding allowable deviation range. When the target processing state includes both the target moisture content and the target uniform wetting state, active wetting stops after the corresponding early stopping conditions are met in both state dimensions.

[0097] Furthermore, refer to Figure 1It can be understood that the collaborative control unit is used to determine the corresponding predicted state change rate based on the current processing state, target processing state, and predicted remaining processing time of various brewing raw materials, and compares the actual state change rate of various brewing raw materials with the predicted state change rate.

[0098] When the deviation between the actual rate of change of any type of brewing raw material and the corresponding predicted rate of change of state exceeds the preset deviation range, the predicted remaining processing time of that type of brewing raw material is re-determined, and it is determined whether its expected completion time deviates from the preset coordination range.

[0099] The predicted state change rate is determined based on the state change trend of the corresponding raw material in the previous prediction period, or based on the current processing state, the target processing state, and the predicted remaining processing time.

[0100] The preset deviation range is used to determine whether the actual processing progress of the current raw materials has deviated significantly from the original prediction. It can be determined based on the allowable fluctuations in state changes during normal system production. In actual operation, the state change rates of multiple consecutive sampling cycles can be compared to reduce false triggers caused by fluctuations in a single detection. When the actual state change rate of a certain type of raw material continuously deviates from the corresponding predicted state change rate, the control terminal re-determines its predicted remaining processing time based on the latest current processing state and the latest state change rate, and updates the estimated completion time accordingly. Only when the updated estimated completion time further exceeds the preset coordination range corresponding to the current convergence time will the re-determination of the convergence time be triggered.

[0101] When the online moisture detection component, temperature detection component, or corresponding sampling data becomes invalid, exceeds the reasonable measurement range, or is continuously missing, the collaborative control unit stops using the new detection value of that channel to update the prediction result and retains the most recent valid state as a temporary reference. If the data is recovered within the preset failure time, the remaining processing time is recalculated based on the recovered valid data. If the data is not recovered after the preset failure time, the automatic water addition control of that channel is stopped, the raw material is isolated from the batching unit, and an abnormal status is output to avoid it from continuing to participate in automatic batching when there is no valid status data.

[0102] Furthermore, refer to Figure 1 It can be seen that when the expected completion time of any type of brewing raw material is delayed and causes the common convergence time to be updated, the collaborative control unit re-determines the waiting time between the cessation of active wetting and the common convergence time for the other types of brewing raw materials based on the updated common convergence time.

[0103] The state migration amount of the remaining brewing raw materials is re-predicted based on the re-determined waiting time. For the remaining brewing raw materials that are still in the active lubrication stage, the early stop state is re-determined based on the re-predicted state migration amount. For the remaining brewing raw materials that have entered the waiting stage, their processing state at the updated common convergence time is re-predicted based on the remaining waiting time. When the predicted processing state is within the allowable deviation range of the corresponding target processing state, the waiting continues. When it exceeds the allowable deviation range, the brewing raw material of this type is kept isolated from the convergence and batching unit, the convergence and batching of this batch is suspended, and an abnormal state is output, so that the processing progress of one type of brewing raw material is linked to the adjustment of the processing state of other brewing raw materials.

[0104] For example, raw materials A, B, and C are actively wetted, with an initial common convergence time of T_c1. When the expected completion time of raw material C is delayed from before T_c1 to after T_c1 due to changes in the initial or actual state of the current batch, the coordination control unit updates the common convergence time to T_c2. At this time, even if the active wettation rates of raw materials A and B do not change, the waiting time from the cessation of active wettation to the common convergence time will increase as T_c2 is delayed. Therefore, the system recalculates the expected state transition amounts of raw materials A and B during the additional waiting time. If raw material A or raw material B is still in the active lubrication stage, a new early stop state is re-determined based on the re-predicted state transition amount, and control continues. If raw material A or raw material B has already entered the waiting stage, the recalculated early stop state is no longer used as the execution condition. Instead, its processing state at T_c2 is re-predicted based on the remaining waiting time. When the predicted processing state is within the allowable deviation range of the corresponding target processing state, the raw material is kept in the waiting hold state. When the predicted processing state exceeds the allowable deviation range, the raw material is kept isolated from the batching unit, the batching of this batch is suspended, and an abnormal status is output. Through this process, the progress change of one raw material can be transmitted to the processing conditions of other raw materials, while avoiding the re-execution of the irreversible "early stop" control on raw materials that have already stopped active lubrication.

[0105] When the expected completion time of a certain type of raw material is brought forward, the common convergence time will not be brought forward directly because of the advance of a single raw material; only when the updated expected completion times of all types of raw materials can meet the earlier common convergence time, and the subsequent mixing process allows for early feeding, will the common convergence time be adjusted to the earlier time, and the waiting time, state migration amount, and early stop status of raw materials that are still in the active lubrication stage will be recalculated.

[0106] Furthermore, refer to Figure 1 It can be seen that a waiting and holding unit corresponding to each type of brewing raw material is provided between the raw material distribution processing unit and the batching and mixing unit;

[0107] The waiting and holding unit is used to independently and temporarily store the corresponding brewing raw materials after they reach the early stop state and the active moistening stops. This allows the brewing raw materials to be left to stand, agitated, or alternately left to stand and agitated while the water addition stops, so that the moisture between the surface and the interior of the raw materials can continue to migrate.

[0108] After all the brewing raw materials participating in this batch of production meet the convergence conditions and reach the common convergence time, the converging and batching unit will transport the brewing raw materials in each waiting and holding unit to the same processing area corresponding to the aroma type of the liquor to be produced, according to the raw material ratio.

[0109] The waiting and holding unit can employ independent temporary storage bins corresponding to each raw material processing channel. The inlet of each storage bin is connected to its corresponding processing channel, and the outlet is connected to the batching and mixing unit via an independently controlled outlet gate, conveying mechanism, or weighing and feeding mechanism. During the waiting phase, the addition of moistening water is stopped. For raw materials requiring a redistribution of surface and internal moisture, a low-speed intermittent agitation method can be used; for raw materials suitable for static migration, static mixing is maintained. Once all the brewing raw materials participating in this batch of production meet the mixing conditions and reach the common mixing time, the batching and mixing unit controls the discharge from each waiting and holding unit according to the raw material ratio corresponding to the aroma type of the liquor to be produced. This allows different raw materials to enter the same processing area corresponding to the subsequent mixing process for mixing, grain preparation, or subsequent brewing treatment.

[0110] Furthermore, refer to Figure 1 It can be seen that the raw material distribution processing unit, raw material status acquisition unit, waiting and holding unit, and batching unit can be set up around each raw material processing channel and communicate with the collaborative control unit. The collaborative control unit receives the current status, expected completion time and waiting status information of each channel, and outputs control commands to the water adding component, the turning component, the discharge control component and the waiting and holding unit respectively, so that each raw material channel can independently complete active lubrication and can also be collaboratively controlled based on the same common confluence time.

[0111] This embodiment provides a raw material processing method for the production of multi-grain aroma-type baijiu, including the following steps:

[0112] S1. Determine the aroma type of the liquor to be produced and the types of brewing raw materials involved in the production, and determine the target processing state of each type of brewing raw material when it enters the subsequent mixing process according to the aroma type of the liquor and the types of brewing raw materials.

[0113] S2. Different types of brewing raw materials are sent to their respective processing areas for active moistening, including adding water and turning. During the active moistening process, the current processing status of each type of brewing raw material is continuously acquired, and the status changes of each type of brewing raw material are determined based on the continuously acquired current processing status.

[0114] S3. Based on the current processing status and status changes of various brewing raw materials, determine the predicted remaining processing time required to reach the corresponding processing requirements, and combine the feeding requirements of the subsequent mixing process to determine the common convergence time of various brewing raw materials entering the subsequent mixing process.

[0115] S4. For each type of brewing raw material, based on the processing state of the raw material when active wetting stops and the interval between the cessation of active wetting and the moment of convergence, predict the amount of state migration of the raw material due to the continued migration of internal moisture after the cessation of active wetting.

[0116] S5. Based on the target processing state and the corresponding state transition amount corresponding to the common convergence of various brewing raw materials, determine the early stop state corresponding to the cessation of active moistening of various brewing raw materials from the target processing state.

[0117] S6. Actively moisten each type of brewing raw material. When any type of brewing raw material reaches the corresponding early stop state, stop the active moistening of that type of brewing raw material and put it into a waiting stage, so as to utilize the internal moisture migration during the waiting stage to change its processing state to the corresponding target processing state.

[0118] S7. During the active lubrication process, continuously update the predicted remaining processing time of various brewing raw materials. When the expected completion time of any type of brewing raw material is delayed and deviates from the preset coordination range, re-determine the common convergence time based on the updated expected completion time of that type of brewing raw material.

[0119] S8. Based on the newly determined common convergence time, redetermine the waiting time between the cessation of active moistening and the common convergence time for the remaining types of brewing raw materials, and re-predict the state migration amount of the remaining types of brewing raw materials based on the newly determined waiting time; for the remaining brewing raw materials that are still in the active moistening stage, redetermine the corresponding early stop state based on the re-predicted state migration amount; for the remaining brewing raw materials that have entered the waiting stage, re-predict their processing state at the updated common convergence time based on the remaining waiting time, and continue waiting when the predicted processing state is within the allowable deviation range of the corresponding target processing state; when it exceeds the allowable deviation range, keep the type of brewing raw material in an isolated state, do not participate in the current batch of batching, suspend the current batch of batching and output an abnormal state, so that the change in the processing progress of one type of brewing raw material will be linked to adjust the processing state of other brewing raw materials;

[0120] S9. After the active lubrication is stopped, each type of brewing raw material undergoes a corresponding waiting stage. When all types of brewing raw materials participating in this batch of production meet the convergence conditions and reach the common convergence time, the various types of brewing raw materials are converged according to the raw material ratio corresponding to the aroma type of the liquor to be produced, so that when the various types of brewing raw materials enter the subsequent process together, they are respectively within the allowable deviation range of the corresponding target processing state.

[0121] The specific execution process of this method is as follows: After receiving the aroma type and raw material combination of the current batch of baijiu, the aroma type target determination unit first determines the target processing state that each raw material should reach when it enters the subsequent mixing process. Each raw material enters its corresponding processing channel for active moistening, and the raw material state acquisition unit continuously collects the current state and calculates the rate of state change. The convergence time determination unit determines the initial convergence time based on the predicted remaining processing time of each raw material and the feeding requirements of the subsequent process. The state migration prediction unit predicts the state migration amount based on the expected waiting time after each type of raw material stops active moistening. The collaborative control unit determines the early stop state of each raw material from the final target processing state. Raw materials that absorb water or change state rapidly can reach the early stop state first and enter the waiting and holding unit, while raw materials that change state slowly continue active moistening. When the expected completion time of slow raw materials is delayed and exceeds the preset coordination range, the system re-determines the common convergence time and processes other raw materials separately: for raw materials that are still in the active lubrication stage, the state transition amount and early stop state are recalculated; for raw materials that have entered the waiting stage, their processing state at the updated common convergence time is re-predicted. If they are within the allowable deviation range of the target processing state, they continue to wait. If they are outside the allowable deviation range, the raw material is kept isolated from the convergence batching unit, the convergence batching of this batch is suspended, and an abnormal state is output until all kinds of brewing raw materials participating in the production of this batch meet the convergence conditions of the current batch.

[0122] It should be noted that the target processing state, early stop state, and state migration amount can be established separately for moisture content, or for moisture content and wettability uniformity. The preset deviation range and preset coordination range are used to determine whether the prediction results and the common convergence time need to be updated, and can be determined based on the state fluctuations allowed by the actual production process and the feeding requirements of subsequent mixing processes. The allowable deviation range of the target processing state is used to determine whether raw materials that have entered the waiting stage can still participate in this batching at the common convergence time, and can be determined based on the corresponding aroma, raw material type, and the target state fluctuation range allowed by the validated production process. The purpose of the above relationships is to ensure that raw material processing control revolves around the "actual state when entering subsequent processes," rather than using a single fixed wettability duration or the time when each raw material reaches its target state as the termination basis.

[0123] Among them, the preset deviation range can be determined by the fluctuation range of the state change rate of multiple historical batches of the same raw material under stable active lubrication conditions; the preset coordination range can be determined by the allowable feeding time window of the subsequent mixing process and the fluctuation range of the normal processing time of each raw material; the allowable deviation range of the target processing state can be determined by the fluctuation range of the qualified state of the corresponding liquor aroma type, raw material type and verified production process.

[0124] The convergence conditions described in this invention refer to the fact that all kinds of brewing raw materials involved in this batch of production are not in an abnormal isolation state, and their predicted processing state at the time of convergence is within the allowable deviation range of the corresponding target processing state; only after the convergence conditions are met and the time of convergence is reached can the convergence batching unit execute the convergence batching of this batch.

[0125] In this invention, the above-mentioned units can be implemented by independent control modules or by the same controller according to the corresponding functional program. The predicted remaining processing time, state transition amount, and early stop state are all dynamically updated based on the actual collected state of the raw materials in this batch. The target state, historical transition relationship, and allowable deviation range involved can be pre-established by verified production process data and corrected according to the actual detection results during operation. Therefore, it can adapt to different fragrances, different raw material combinations, and different production batches without changing the core collaborative control logic of this invention.

[0126] In this invention, for mechanical connection methods, detection components and execution components that are not particularly limited, conventional structures in the art that can achieve the corresponding detection, conveying, watering, turning and control functions can be adopted; their specific models do not constitute a limitation on the scope of protection of this invention.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
