Description

Technical Field

[0001] The invention relates to the technical field of primary tea processing, and is mainly applied to a comprehensive primary tea processing system and a processing technology for an automated tea production line. Background Art

[0002] Tea is China's national drink and one of the oldest and most widely consumed beverages in the world. There are many types of tea, including green tea, black tea, oolong tea, white tea and dark tea. Each type of tea has its own unique flavor and characteristics, satisfying people's pursuit of different tastes and needs. With people's continuous exploration of tea making techniques, various tea making techniques have emerged one after another, and the process has been continuously refined, and new models have also been born.

[0003] Private customized tea and services are an emerging tea adoption investment model that is different from the traditional tea sales model. The main feature of this model is that you can customize your favorite tea varieties and processing methods according to the needs of individuals or groups, while enjoying the fun of adopting a tea garden. Specifically, private customized tea projects are usually adopted in tea gardens, and the adoption cycle is generally five years. Adopters can choose to adopt in a specific tea garden and enjoy the benefits of tea production. During this period, the tea garden owner will plant and manage tea varieties according to the requirements of the adopters and their preferences and needs.

[0004] During the tea harvesting season, adopters and their relatives and friends can bring their relatives and friends into the tea garden to personally experience the fun of picking fresh leaves and participate in the tea processing process. This sense of participation can make adopters closer to the tea production process and enhance their knowledge and understanding of tea. After the tea is picked and processed, the tea will be beautifully packaged and the outer packaging can be customized according to the requirements of the adopter, such as adding a personal or group brand logo to increase the personalization and customization of the tea. Finally, adopters can enjoy convenient and fast service, and the finished tea can be delivered directly to their homes free of charge, allowing adopters to easily taste high-quality tea.

[0005] This kind of private customized tea project is popular with tea growers and investors because it can meet consumers' pursuit of tea quality and personalized needs, and it is also conducive to tea growers to achieve differentiation and value-added in tea sales. This model has certain development potential in the tea industry and can inject more innovation and vitality into the tea industry. Therefore, for such an emerging model, how to do a good job in quality management and efficient processing is very important.

[0006] In terms of processing technology, the process of withering fresh leaves, rolling, and drying forms the green tea process; on the basis of the green tea process, adding the higher degree of fermentation to the pile process forms the black tea process; on the basis of withering, adding rolling, fermentation, and drying steps to form a new tea-making process has becomeBlack tea process ; Only withering and drying are white tea processes; from picking fresh leaves to spreading, killing green, rolling, and sun drying are the processing processes of Pu'er tea sun-dried green tea. The tea processed by these processes is raw tea, which is made through the primary processing link. The primary processing of tea seems simple, but it is directly related to the quality of the finished product. Its processing technology and methods play a key role in the quality, taste and nutritional content of tea. The traditional tea processing process requires a lot of manpower and time, and the process is complicated, the degree of mechanization is low, and the processing environment is worrying, which is not conducive to the stability of efficiency and product quality. However, the application of existing automated equipment in the primary processing of tea is limited, and it cannot meet the automated processing needs of various types of tea.

[0007] On the other hand, the initial processing of tea is lagging behind and the degree of mechanization is low.

[0008] Yunnan Province's tea processing is characterized by "small scale, poor equipment, and weak strength". Many processing plants in the province have outdated equipment and a poor processing environment, resulting in uneven quality and low efficiency of raw tea products. Most tea processing plants are family workshops. On the one hand, the entry threshold is low and disorderly competition is prominent in the processing. On the other hand, there are few standardized processing plants, a shortage of construction land indicators for processing plants, and a lack of land guarantee.

[0009] Investment in the scattered primary processing links is seriously insufficient. Raw tea is purchased from ordinary people, or simple primary processing plants are built to produce it, making shoddy production a habit in the industry.

[0010] The outdated and outdated production methods in the early days were too extensive, leaving people with a poor impression of hygiene. Under the pressure of the market, some people thought about standardized production, some watched and some put it into practice.

[0011] The current private customized tea processing model has some shortcomings and defects when facing fresh leaf processing. First, the application of existing automated equipment in the primary processing of tea is limited and cannot meet the automated processing needs of various types of tea. This results in more manual operations being required during the private customized tea processing, reducing processing efficiency and production capacity.

[0012] Secondly, the processing of customized tea is usually concentrated during the tea collection period, which leads to independence, decentralization and a wide variety of categories in the processing process. However, traditional tea primary processing equipment can usually only provide fixed processing categories and cannot meet personalized and diversified needs. This makes it easy to queue up when the number of processing orders is concentrated, resulting in the failure to process fresh leaves in time, and the stacking is squeezed and airtight, which may lead to the problem of reduced tea quality.

[0013] In addition, the market currently lacks a set of tea processing systems and processes that are efficient, comprehensive, and capable of processing multiple categories at the same time. This makes the processing efficiency of customized tea processing low and cannot meet the processing needs of a large number of scattered orders and a variety of processing types. Summary of the invention

[0014] In order to solve the problems and shortcomings of the above-mentioned prior art, the inventor has developed and designed a comprehensive tea primary processing system and processing technology. The present invention plans and monitors the processing process in real time through the main control module to improve the efficiency and quality of tea production and processing. By analyzing the input information of fresh tea leaves, the station parameter information of each processing equipment and the processing type information, and according to the processing flow and the operating status of the equipment, an efficient processing plan is formulated. The processing equipment at each station is equipped with a sensor that can detect the operating status of the equipment and record the processing batches in real time, realize the monitoring and tracking of the processing links, and thus efficiently utilize the entire processing system. Through intelligent scheduling and control, the entire system can realize efficient and comprehensive processing of various types of tea while ensuring the processing quality.

[0015] Specifically, the working principle of the present invention is:

[0016] 1. Main control module: It is the core control program of this system. It is responsible for receiving, analyzing and processing the processing information of each process station, and formulating and monitoring the processing plan in real time. The main control module can obtain the station parameter information through the sensors connected to each station, such as material processing information, standby status, station operation time, process remaining time, process parameter information and planned time information. The main control module can also receive the input information and processing type information, calculate the current or expected processing task time based on this information and the parameter information of the process processing equipment, and display the current processing progress and the types of tea that can be processed through the interactive interface or control interface; and can control the processing equipment by monitoring and controlling the process parameters of each process equipment to realize the operation of the automatic program.

[0017] 2. Each station of the comprehensive processing system: It constitutes the main part of this system and is also the core structure of this system. The comprehensive processing system includes feeding station, spreading station, two-way conveyor, killing station, cooling and moisture recovery station, rolling station, block deblocking station, fermentation station, drying and discharging station and sun drying and discharging station. The process processing station uses automated process processing equipment for automated processing, which can automatically feed, automatically discharge, and monitor the status of materials throughout the process, such as temperature and moisture content, which are supervised and controlled by the main control module. There are several two-way conveyors, which can transport materials to different subsequent process processing stations through forward and reverse bidirectional transportation, connect the stations, and realize the combined use of multiple stations. They can be combined and connected according to the processing flow, realizing the automated operation of the entire process of processing various tea varieties, and are necessary components of comprehensive processing. Each station is equipped with corresponding processing equipment and sensors, such as inlet and outlet detection sensors and processing batch counters. These sensors can detect the operating status of the equipment and obtain time information of the start and end time of processing, which is used to track, process and manage a single batch of tea materials.

[0018] 3. Variety processing plan: It is a comprehensive processing plan for various tea varieties. Based on the processing type information of the tea materials, the feed information of the tea materials themselves and the station parameter information of the relevant process processing stations, the corresponding processing plan can be formulated after comprehensive calculation. It extracts the stations and station sequence required for various tea processing according to the processing type information, and distributes the processing station tasks in order according to the processing number. The main control module calculates the planned processing time of each station, groups them according to the processing number, and establishes a continuous processing production plan between each station by batch, that is, according to the station sequence and time sequence, plans the processing task time of a complete tea primary processing and the maximum processing volume that can be processed, and provides a display. After inputting the specific expected processing amount of tea and processing varieties, it can also be re-predicted and estimated according to the input value, and the production expected processing task is provided. The main control module can also calculate and deduce the waiting processing time of the materials to be processed and the material processing volume and expected processing time corresponding to various tea varieties based on the feed information of the materials to be processed, the current station parameter information of each station and the existing planned processing task time, so as to facilitate the arrangement and preparation of subsequent processing tasks.

[0019] 4. Sun-drying and discharging station: It is the subsequent station of tea processing, but it is also the most time-consuming station. Once the station is occupied, the materials that need to be sun-dried in the future may be suspended and postponed, and even tasks cannot be added. Therefore, the sun-drying and discharging stations are equipped with as many low-temperature drying equipment as possible according to the size of the site, and the main control module monitors their operating status. The main control module can obtain the number of low-temperature drying equipment and the number of equipment currently or planned to be running, and calculate the amount of material that the planned idle equipment can process based on the number of planned idle equipment, and feedback to the interactive interface or control interface for display. If the amount of material that the idle equipment can process is sufficient to meet the amount of material planned to be processed, and the planned processing tasks of the previous station can also be carried out when the planned idleness is in place, the system will display a processing information prompt on the interactive interface or control interface.

[0020] The above technical scheme plans and monitors the processing process in real time through the main control module to improve the efficiency and quality of the production and processing of various varieties of tea. The main control module analyzes the input information, station parameter information and processing type information, and formulates an efficient processing plan based on the processing flow and the operating status of the equipment. The processing equipment at each station is equipped with sensors that can detect the operating status of the equipment and record the processing batches in real time to monitor and track the processing links. The number and idleness of the equipment at the sun-drying and discharging stations are also taken into account to improve the overall processing efficiency of the system. Through the intelligent scheduling and monitoring of the main control module, the entire system can realize the efficient and comprehensive processing of tea, improve the processing capacity per unit time, and minimize the proportion of idle equipment to improve the overall processing efficiency. It is very suitable for the field of centralized, diversified and automated tea processing for customized tea.

[0021] Beneficial technical effects of the present invention:

[0022] (1) Improve production efficiency: Through the intelligent scheduling and monitoring of the main control module and the real-time monitoring of the equipment operation status, the system can optimize the processing flow, reduce the idle rate of idle processing equipment, and improve processing efficiency.

[0023] (2) It realizes the comprehensive processing of multiple types of tea and can be applied to the primary processing technology of processing multiple types of tea, such as preparing Pu'er tea, roasted black tea, sun-dried black tea, green tea and white tea, to meet the market's diversified tea needs. At the same time, it is well suitable for the customized tea production and manufacturing model, solving the problems of difficult centralized processing and low processing efficiency;

[0024] (3) Stable quality of tea material primary processing products: The system can adjust the process parameters in real time by monitoring the workstation parameter information and processing flow to ensure the accuracy and stability of the processing process. At the same time, the main control module can formulate corresponding processing plans based on the characteristics and needs of the tea types to ensure the quality consistency and stability of each batch of products, thus achieving homogenized and standardized primary processing production.

[0025] (4) Reduce labor costs: The traditional tea processing process requires a lot of manpower operation and supervision. After adopting this technical solution, the main control module can automatically allocate work tasks and plan production, reducing manual intervention and supervision, reducing labor costs, and reducing energy consumption and environmental pollution, which is in line with the concept of green environmental protection.

The equipment automatically loads and discharges materials, and the running speed is adjustable. The multi-layer cooling and rehumidification machine allows the tea leaves to fully rehumidify and evenly distribute the moisture. It is used to quickly reduce the temperature of the materials for cooling. The discharge port is connected to the rolling station.

[0037] Rolling station; For example, the automatic rolling system can realize automatic feeding, automatic weighing, and automatic rolling of tea leaves.

[0043] Drying and discharging station: used to provide equipment and areas for primary drying, cooling, and re-drying to carry out high-temperature drying of materials, and discharging after completion; such as dryers, materials are dried at high temperatures to remove a large amount of grass smell. After the primary drying is completed, the materials are transported to a cooling and rehumidifying machine, and then enter another dryer, where the low-temperature slow drying fully stimulates the aroma of the materials. After the re-drying is completed, the materials are cooled during the transportation process and then enter the weighing and packing (or bagging) platform. After weighing, they are stored or processed in other ways.

[0045] Processing station hardware facilities:

[0046] Spreading station (single-layer structure): The structure is designed to adopt a single-layer structure. The spreading machine is 12 meters long and 1.38 meters wide, with 16.5 square meters per machine, which can meet the processing requirements of 1200kg / batch of fresh leaves in the black tea production line. Functional features: automatic loading and unloading; automatic air blowing, variable wind speed and adjustable time.

Functional features: automatic loading and unloading; automatic air blowing, wind speed and time frequency conversion adjustable.

[0048] Withering station: The structural design is composed of a drum main unit and an independent heating air supply system. The drum has a diameter of 800mm and a length of 4200mm. It is equipped with a metering, leaf leveling device and a dehumidification device. The hot air temperature is set at 350℃~450℃. Functional features: automatic feeding, automatic leaf leveling, and automatic discharging; fresh leaf feeding flow control, drum speed, and dehumidification fan frequency conversion are adjustable; withering time, hot air temperature, and hot air volume are adjustable. The withering equipment is a pan-frying or drum type. The temperature and time must be automatically adjusted and controlled by the equipment system according to the actual amount of tea, the tenderness (grade) of the tea leaves, the moisture content and other factors. After the withering is completed, there is still a lot of moisture in it. Under the principle of thermal expansion and contraction, the cell wall breaks faster, and more substances are dissolved, so the soup is easy to become turbid. Therefore, in general, we will let it cool before rolling. After the withering, the color of normal tea leaves changes from bright green to dark green or dark green. Then the tea leaves are spread out to cool and ready for rolling. Conventional process parameters:

[0049] Chaotianguo killing time: 12-15min

[0050] Killing temperature: set at 260℃, put tea leaves in at 250℃

[0051] Moisture: Reduce by 5-10%

[0052] Drum tea-fixing machine: Fixing time: 2-5min

[0053] Fixing temperature:

[0054] The temperature detection is set at the front section, rear section and exit of the drum, and the temperatures are 280℃, 260℃ and 70℃ respectively. However, the temperature did not reach the preset value when the material was fed, and the temperature was displayed as 266℃, 259℃ and 69℃ when the material was fed.

[0055] The drum temperature is set according to the state of the tea leaves. Generally, the temperature at the discharge port is low (below 100°C), and the temperature at the entrance and the middle section is between 200 and 290°C. If there are many tea stems, the amount of feed should be reduced. The edges of the tea leaves should be slightly charred to ensure that the stems are basically cooked.

[0056] Moisture: Reduce by 5-10%

[0057] Fixing temperature: electromagnetic fixing machine 90~150℃, high temperature drum fixing machine 200~290℃.

The 55-type rolling barrel has a barrel diameter of 550mm and a height of 550mm. The rolling time for each barrel of green tea is about 30 minutes, and the rolling time for each barrel of black tea is 80 minutes. Functional features: automatic feeding and discharging; automatic weighing and metering, automatic pressure rolling, and the speed of the rolling plate is variable and adjustable. Rolling time: 10-25 minutes, the weight of fresh leaves is reduced by 30-40% after rolling, and the moisture is reduced to 10-15% of the fresh leaves. The rolling cell breakage rate: 45-60%, the strip formation rate: ≥60-85%;

Functional features: automatic loading, automatic leaf leveling, automatic discharging; automatic ventilation, adjustable fermentation temperature, humidity and time; visual design of the fermentation room.

[0062] Cooling machine: It is a hexagonal design that uses wind and fan to cool the withered leaves.

[0063] Wind separator: It is a three-mouth design that uses wind power to separate floating objects and impurities in tea leaves.

[0064] Deblocking machine: uses high-speed rotating deblocking pieces to dissolve tea leaves and automatically loads and discharges materials.

[0065] Moisture Reconditioning Machine: It is a multi-layer frame design, equipped with feeding, leaf leveling mechanism, and discharging conveyor, which can evenly distribute moisture.

[0066] Sun drying: Sun drying refers to the drying method of Pu'er raw tea. The rolled tea is placed under natural sunlight for drying, which effectively retains the growth possibility of active substances in tea leaves and creates potential vitality for Pu'er tea to become more fragrant with age. Low-temperature dryers, multi-layer belt-type box drying equipment, hot air and sunlight simulation irradiation; or merchants with conditions can choose to dry the tea on their own.

[0067] In terms of control, in this embodiment, the main control module can obtain processing plan information based on the processing type information, feed information and station parameter information of the material to be processed, and the processing plan information includes the types of tea that can be processed currently or after a certain period of time; the specific calculation is based on various current automated processing equipment, which can feedback equipment parameters, such as equipment power, production capacity, temperature and humidity control values, etc., combined with the information data of the fresh leaves to be processed, such as processing volume, volume, moisture content value, material temperature, etc., based on the processing volume and target value, it is possible to deduce the parameter values ​​that need to be set for the equipment, the operating power of the equipment, etc., and the time value required to complete the processing can be calculated, which are all processing plan information;

[0068] Based on the processing type information, it can extract all the stations and station sequences involved in various tea processing, assign a processing number based on the processing, and distribute the processing station tasks to each station in order according to the processing number;

[0069] Based on the input information of the material currently being processed, the station parameter information, station tasks, and processing number of each station, the planned processing time of each station can be obtained, and grouped by processing number, and the processing task time of a complete tea primary processing can be planned according to time based on the station sequence. The processing task time includes the estimated processing unit time of each station after being arranged in order of processing number and time; based on the above-mentioned processing plan information and time value, the planned processing task time of the process processing station can be obtained, and according to time, batch, and processing order, it can be obtained whether the planned processing volume can be completed and the required time;

[0070] Based on the processing task time, the current processing progress, the types of tea that can be processed subsequently, and the waiting processing time can be displayed on the interactive interface or control interface, and can be displayed on the interactive interface or control terminal for the operator to select and operate.

[0071] Specifically, the system includes the following sensor equipment and facilities, but is not limited thereto, and is installed in the processing equipment of each processing station:

[0072] Inlet and outlet detection sensors are used to detect the operating status of the equipment and obtain the time information of the processing start time and end time, and can detect the operating status of the processing equipment;

[0073] The processing batch counter is used to record the number of times the equipment currently processes materials, and based on the processing batch, the material batch processed by the processing equipment can be known, so that the control module can monitor and track the processing links of the same batch of materials.

[0074] In the preferred solution, the sun drying and discharging stations are the stations that take up the longest time. Therefore, whether they are running at full capacity will directly affect the efficiency of the entire integrated processing system. Therefore, it is usually necessary to arrange several low-temperature drying devices. The main control module can obtain the total number of low-temperature drying devices, the number of devices that are currently or planned to be running, and the number of devices that are currently or planned to be idle. It can also convert the amount of materials that can be processed by the planned idle equipment based on the number of planned idle equipment, and feedback to the interactive interface or control interface for display; if the amount of materials that can be processed by the idle equipment is sufficient to meet the amount of materials to be processed, and the planned processing tasks of the preceding stations can also be planned to be idle, then the interactive interface or control interface will display a prompt that the processing can be performed. Similarly, the spreading station can also be equipped with several spreading equipment, which can simultaneously spread and process different batches of fresh tea leaves; it can be manually operated or selected by the system control. The main control module can obtain the total number of spreading equipment, the number of devices that are currently or planned to be running, and the number of devices that are currently or planned to be idle. It can also convert the amount of materials that can be processed by the planned idle equipment based on the number of planned idle equipment, and feedback to the interactive interface or control interface for display;

[0075] In the preferred embodiment, the main control module can calculate and deduce the waiting processing time for processing the material to be processed based on the input material information of the material to be processed inputted through the interactive interface or control interface and the current station parameter information of each station; the main control module can calculate and display the material processing amount and estimated processing time corresponding to the various tea varieties that can be planned to be processed based on the current station parameter information of each station and the existing planned processing task time. That is, the main control module has the function of calculation and deduction, and can calculate the waiting processing time for processing the material to be processed based on the input material information of the material to be processed inputted through the interactive interface or control interface and the current station parameter information of each station. The main control module can also calculate the material processing amount and estimated processing time corresponding to the various tea varieties that can be planned to be processed based on the current station parameter information of each station and the existing planned processing task time, and display them. In other words, the main control module can help plan the quantity and time of tea processing tasks through calculation and prediction, and provide them to the operator for reference and decision-making. Specifically, it can be displayed on the interactive interface that in the next processing task, information such as which types of tea can be processed immediately or will be processed, the processing quantity, the waiting time, the estimated completion time, etc. can be displayed. The operator can complete the operations and inputs of subsequent processing types based on the system feedback prompts.

[0076] Embodiment 2: Based on the above-mentioned comprehensive tea primary processing system, this embodiment introduces a comprehensive tea primary processing process, which includes the following steps:

[0077] Step S1, detecting that each processing station and the bidirectional conveyor in the comprehensive tea primary processing system are in an online standby state, obtaining the feeding information and processing type information of the fresh leaves to be processed in the feeding station, taking Pu'er raw tea processing as an example, the feeding information includes manual or automatic input, the moisture content of the fresh leaves is 80%, the processing amount is 120kg, and the processing type is Pu'er raw tea;

[0078] Step S2, based on the input information and processing type information of the fresh leaves to be processed, the processing routes and process stations involved in the processing procedures are obtained, and the planned processing time of each corresponding process station is calculated in combination with the station parameter information of the stations involved, and the process stations and the bidirectional conveyor corresponding to each processing link of the batch of fresh leaves are given batch identification; the process stations can feedback the station operation status and can receive the work task plan; specifically: the processing route involved includes the input station → Green leaf spreading station → first two-way conveyor → forward rotation → green leaf killing station → cooling and moisture regaining station → rolling station → block breaking station → third two-way conveyor → forward rotation → sun drying and discharging station; Green leaf spreading station is based on the data of 120kg of initial fresh leaves and 80% moisture content. It is calculated that three green leaf spreading machines are needed, each with a processing capacity of 40kg, a target moisture content of 70%, and a time of 3h. The estimated discharge weight is 108kg and is marked as batch 1. The green leaf spreading machine processing task is issued, and the planned data information is sent to the green leaf killing station. Based on the expected incoming material information and its own equipment parameters, power and other processing capabilities, the withering station estimates that one Chaotian pot is needed for automatic withering, with a processing efficiency of 60kg / h, an estimated completion time of 1.5h, an estimated material moisture content of 60%, and a weight of 95kg. The Chaotian pot automatic withering machine is issued, and the planned data information is sent to the cooling and rehumidification station. The cooling and rehumidification station takes 0.5h to process, and then enters the rolling station. The rolling machine can be calculated based on the data, and two rolling machines are needed, each processing 48 kg, the estimated processing time is 1h, the estimated material weight is 90kg, and it is sent to the deblocking machine. Based on the estimated processing volume and its efficiency value of 300kg / h, the deblocking machine obtains the time required for deblocking of 0.2h, and estimates the amount of material after deblocking and discharging to be 90kg, which is sent to the sun-drying and discharging station. The sun-drying and discharging station is calculated based on the material thickness of 20mm. The area for drying tea per square meter is 2kg. It is calculated that 45㎡ will be occupied, and a sun-drying low-temperature drying equipment will be required. The operating time is 4h, and the processing can be completed after discharging. It can be seen that each station equipment can obtain the estimated processing time value based on the calculated value, and the time to complete the processing, the operating time required for each equipment, and the specific time value can be planned in chronological order. The rest of the time is idle time.

[0079] Step S3, based on the batch identification of each process processing station and the bidirectional conveyor, according to the expected processing or passed processing time, a processing task for a single process processing station or a bidirectional conveyor is formed, and the task is issued to the process processing station or the bidirectional conveyor, and the system is started to feed the material; it can be operated according to the above plan, based on batch verification and time sequence, the equipment can know the current material batch being processed and the corresponding processing task, thereby realizing an accurate automated processing flow; the material batches are sorted based on the start time of the first process processing station.

[0080] Step S4, each process station sequentially processes and discharges the same batch of materials, sequentially completes the processing process of the corresponding tea varieties, and feeds back the estimated idle time of the process station; the tea varieties include Pu'er raw tea, roasted black tea, sun-dried black tea, white tea or green tea;

[0081] Step S5, extracting the time information and station parameter information of each process processing station in the expected idle time according to the time continuity condition for deduction: matching with the process processing stations required for the complete processing of various tea types with the minimum processing volume, screening out the tea types that can complete the processing, calculating and sequentially displaying the expected processing time and theoretical processing volume upper limit of the corresponding tea types;

[0082] Step S6: Based on the tea types that can be processed displayed in step S5, input the tea type information, feed information and batch identification of the next batch to be processed;

[0083] Step S7: Based on the information of the type of tea to be processed in the next batch and the information of the input materials, and the station parameter information of the next batch of materials to be processed, the process processing stations to be traversed by the next batch of processing are output, and the estimated processing tasks and the estimated completion time are issued;

[0084] Step S8, repeating steps S5 to S7 until there is no more processing information that can be processed, and then the expected processing tasks will not be displayed any more.

[0085] The estimated idle time is the time when the process station is not in operation outside the batch and is waiting for empty materials, but does not include the planned processing time of the estimated processing tasks that have been issued. Figure 2 As shown in the figure, it shows a schematic diagram of the processing types within a period of time, among which the color of batch ① is Pu'er raw tea, the color of batch ② is sun-dried black tea, the color of batch ③ is green tea, and the color of batch ⑤ is white tea. The system first calculates the required workstations and estimated time for the processing of batch ①, such as Figure 2As shown in the yellow area in the middle, therefore, the blank sections in other non-yellow areas are all the estimated idle time of the workstation. The system can prompt the estimated processing information of various tea varieties that can be processed within the estimated idle time. For example, after entering the processing volume of sun-dried black tea, the system matches the batch identification of its second batch, and uses the time node of the rolling station as the earliest starting time point, and calculates the time points of the spreading station and other stations of the sun-dried black tea, and calculates the time required for each station according to the processing volume. At this time, for the system, the estimated idle time changes, and the other blank sections that are non-yellow and non-magenta are the estimated idle time. When the operator enters green tea as the processing task, the system matches the batch identification of its third batch, and uses the first idle time of the spreading station as its starting time node, and so on. As shown in the figure, within 20 hours, a total of five batches of five types of tea are processed, among which the occupancy time of the spreading station, the occupancy time of the fermentation station, and the sun-drying station time are the three stations with the highest occupancy rate.

[0086] Preferably, the system can determine whether the low-temperature drying equipment at the sun drying and discharging stations in each batch of processing tasks is running at full capacity. If it is not running at full capacity, the system can obtain the number of idle low-temperature drying equipment and calculate its maximum processing capacity.

[0087] Within the maximum processing capacity of the idle low-temperature drying equipment obtained, reverse calculation is performed to display the tea varieties that need to be sun-dried and their processing volume thresholds, and the required process processing stations and planned processing time are reversed, and matched with the process processing stations that can be used within the estimated idle time, and the tea processing varieties that can be used simultaneously with the idle low-temperature drying equipment and the estimated processing volume information are screened and displayed, and the information is fed back to the interactive interface or control interface for display.

[0088] Similarly, because the system can process different batches of fresh tea leaves at the same time, if there is tea material that has been spread in other spreading equipment before processing and can be immediately processed in the subsequent process, the estimated processing time and estimated idle time of the spreading station will not be used when calculating the estimated processing information. This can further improve the utilization rate of other process processing stations and maximize the efficiency of comprehensive processing.

[0089] like Figure 3 As shown, there are tea materials that have been spread in other spreading equipment before processing and can be immediately used for subsequent processes. Figure 3 Batches No. 6 and No. 7 have already completed the green tea spreading process in advance and then entered this processing system for task allocation. At this time, the green tea spreading process is not considered, and the processing tasks of green tea and white tea scheduled nearby are directly carried out.

[0090] Processing procedures for different types of tea:

[0091] Pu'er raw tea production process: After being manually harvested, the fresh leaves are temporarily stored in the fresh leaf temporary storage area, and then enter the green spreading machine as required. Through dynamic transportation, storage, and airing, the moisture content of the fresh leaves is reduced and the processing resistance is increased. Then the materials fall into the first two-way belt conveyor through the conveying equipment. When the first two-way belt conveyor rotates forward, the materials are conveyed into the green fixing machine. Through the high-temperature rotation of the drum, the moisture content of the materials is evenly evaporated, and a large amount of grassy taste is removed at the same time. The green fixing materials are cooled and conveyed to the rolling machine for rolling; the rolled materials are conveyed to the deblocking and shaking screen machine through the conveying equipment to separate the larger agglomerated tea blocks and screen out some ash and powder. The materials after the deblocking and shaking screen are sent to the third bidirectional belt conveyor. When the third bidirectional belt conveyor rotates forward, the materials fall into the vertical elevator and are lifted to the second-floor drying room. Multiple two-layer mesh belt tea drying machines are arranged in the drying room. The materials are spread to the upper layers of each tea drying machine in turn through the conveying and paving equipment for solar drying. When the tea leaves on the upper mesh belt are dried to a certain moisture content and the next batch of tea leaves needs to be solar dried, they are transported to the lower mesh belt to continue drying to the required moisture content, and then transported to the manual boxing (or bagging) station. After weighing, they are stored or processed in other ways.

[0092] Production process of roasted / sun-dried black tea: After being harvested manually, the fresh leaves are temporarily stored in the fresh leaf temporary storage area and then enter the green leaf spreading machine as required. Through dynamic conveying, storage, and drying, the moisture content of the fresh leaves is reduced and the processing resistance is increased. Then the leaves fall into the first bidirectional belt conveyor through the conveying equipment. When the first bidirectional belt conveyor reverses, the materials fall into the second bidirectional belt conveyor. When the second bidirectional belt conveyor rotates forward, the materials enter the rolling machine through the conveying equipment. The rolled materials enter the deblocking and shaking machine through the conveying equipment to separate the larger tea blocks and screen out some ash and powder. The materials after the deblocking and shaking machine are sent to the third bidirectional belt conveyor. When the third bidirectional belt conveyor reverses, the materials are sent to the fermentation room through the conveying equipment. After fermentation is completed, they are transported to the fourth bidirectional belt conveyor. (1) When the fourth bidirectional belt conveyor rotates forward, the materials enter the dryer and are dried at high temperature to prevent the materials from continuing to ferment, prevent mildew, and remove a large amount of grass smell. After the initial drying, the material is transported to a cooling and rehumidifying machine, and then to another drying machine, where the aroma of the material is fully stimulated by slow low-temperature drying. After the secondary drying, the material is cooled during the transportation process and then enters the weighing and packing (or bagging) station. After weighing, it is stored or processed in other ways; (2) When the fourth bidirectional belt conveyor reverses, the material is transported to the vertical elevator, lifted to the second-floor drying room, and enters the drying machine through the conveying equipment. After drying to the specified moisture content as required, it is transported to the weighing and packing (or bagging) station. After weighing, it is stored or processed in other ways.

[0093] White tea production process: Fresh leaves are manually harvested and temporarily stored in the temporary storage area. They enter the drying machine as required. Through dynamic transportation, storage, and drying, the moisture content of the fresh leaves is reduced and the processing resistance is increased. Then they fall into the first two-way belt conveyor through the conveying equipment. When the belt reverses, the material falls into the second two-way belt conveyor. When the second two-way belt conveyor reverses, the material enters the vertical elevator through the conveying equipment, is lifted to the second-floor drying room, and enters the drying machine through the conveying equipment. After being dried in the shade to the required moisture content, they are transported to the manual boxing (or bagging) station. After being weighed, they are stored or processed in other ways.

[0094] Green tea production process: After the fresh leaves are harvested manually, they are temporarily stored in the fresh leaf temporary storage area and enter the green leaf spreading machine as required. Through dynamic conveying, storage, and drying, the moisture content of the fresh leaves is reduced and the processing resistance is increased. Then the materials fall into the first two-way belt conveyor through the conveying equipment. When the first two-way belt conveyor rotates forward, the materials are conveyed into the green tea fixing machine. Through the high-temperature rotation of the drum, the moisture content of the materials is evenly evaporated, and a large amount of grassy taste is removed at the same time. The materials after green tea fixing enter the rolling machine through the cooling conveying equipment for rolling; the rolled materials enter the block-breaking and shaking screen machine through the conveying equipment to separate the larger agglomerated tea blocks and screen out some ash and powder. The materials after the block-breaking and shaking screen machine are sent to the third two-way belt conveyor. When the third two-way belt conveyor reverses, the materials are sent to the fermentation room through the conveying equipment and then sent to the fourth two-way belt conveyor at the rear end through the belt forward rotation. When the fourth two-way belt conveyor rotates forward, the materials enter the dryer and remove a large amount of grassy taste through high-temperature drying. After the initial drying, the material is transported to the cooling and rehumidifying machine, and then enters another dryer to fully stimulate the aroma of the material through low-temperature slow drying. After the secondary drying, the material is cooled during the transportation process and then enters the weighing and packing (or bagging) station. After weighing, it is stored or processed in other ways.

[0095] Preferably, the grade of tea material to be processed and the processing parameters of different tea grades are different. The processing of different grades of tea will be carried out according to the corresponding processing standards, which will affect the processing time, as well as the material quantity, moisture content and volume of the tea material to be processed, which are input manually or input after automatic detection by the system. The processing equipment of each process treatment station will calculate according to the equipment power, operating speed and processing volume to obtain the time after the process is completely completed at the process treatment station; the time for the process treatment station involved in the process to be processed and the two-way conveyor to process the fresh tea leaves to be processed is the planned processing time, and includes batch identification. The planned processing time is processed and calculated in batches for each batch.

[0096] Preferably, the main control module can calculate and deduce the waiting processing time for the material to be processed, obtain the estimated time for each tea processing task corresponding to each processing station in the entire processing task chain, and then number the tea processing of each category by batch number, obtain the processing time data of the processing station corresponding to each processing link of each tea, and start from the second variable-speed processing station for each processing link of each tea, and compare the difference between the start time t1 of the processing task and the end time t0 of the previous processing task at the station. If the time t1 itself is greater than the first predetermined value, and the time difference between t1 and t0 is greater than the time amount of the second predetermined value, if the estimated processing time of the previous variable-speed processing station is greater than the first predetermined value, then based on the time difference, it is calculated that the time difference corresponding to the processing station should be eliminated or reduced, and then Calculate the processing compensation amount and compensation power that the previous variable-speed station should make, and issue an instruction to enable the spare station when the previous variable-speed station is processing, and add a compensation material distribution mechanism at the feed conveying end to feed the amount of tea material corresponding to the processing compensation amount to the spare station, and feedback the estimated processing time t1' of the next processing station after the compensation processing in the task system, and re-update the estimated processing time of the subsequent associated processing stations in the entire planned processing task; the variable-speed processing station described in this embodiment refers to a station that can shorten the processing time by using the spare station, and the fermentation station, the sun-drying station, and the drying station are non-variable-speed processing stations; the first predetermined value means that the processing time of the processing technology is generally long, and the second predetermined value means that the time interval between the two previous and subsequent processing at the same processing station is long;

[0097] Taking this embodiment as an example, Figure 3 In the example of the No. 1 Pu'er raw tea processing, the second variable speed processing station is the killing station, and its starting time t1 is 23:00. The last block-breaking station was completed at 22:00, which is greater than 30 minutes, that is, the first predetermined value. It is necessary to compensate for the processing. Then it is deduced upward to the spreading station of the first variable speed processing station. The duration of the spreading station processing is greater than the first predetermined value, and the difference between the time of the last killing station and the end time of 58 minutes is also greater than 30 minutes, that is, the second predetermined value. The system judges that it is worth compensating, and analyzes the speed-up method of the spreading station. If the efficiency of spreading can be improved by adding spreading stations to shorten the time, then analyze and calculate the amount of tea that needs to be compensated, so that the time of the entire spreading process is reduced by at least 58 minutes, then the killing station can be started at most 58 minutes in advance, and the subsequent processing stations can also be processed in advance, so as to further optimize the system and reduce the idle rate of each processing equipment as much as possible. Thereby improving the overall comprehensive processing efficiency.
