DETAILED DESCRIPTION

[0052] The present application will be further described by the description of specific embodiments, but this is not a limitation of the present application. Those skilled in the art can make various modifications or improvements according to the basic idea of the present application, as long as they do not deviate from the basic idea of the present application, which are within the scope of the present application.

[0053] In a first aspect, the embodiments of the present application provide a tea leaf production method, which comprises the following steps 10 to 80.

[0054] In step 10, the finished and cooled tea leaves are placed into the first conveying elevator 18 of the feeding mechanism 2, and the finished and cooled tea leaves are conveyed to the feeding box 3 of the feeding mechanism 2 through the first conveying elevator 18.

[0055] The use of the first conveying elevator 18 improves the automation level of the tea processing process, reduces the need for manual operation, ensures continuous material supply, and helps maintain the efficient operation of the production line. In addition, through the standardized conveying process, the quality of the tea entering the subsequent process can be better controlled.

[0056] In step 20, when the finished and cooled tea leaves received by the feeding box 3 reach a preset weight, the finished and cooled tea leaves are transported to one of the multiple fixation machines 4.

[0057] Batch management according to the preset weight ensures that each fixation process is carried out under the same conditions, which is beneficial to the consistency of quality, and different fixation machines can be selected according to production needs to improve the flexibility and efficiency of production. By reasonably allocating tasks to different fixation machines, the production equipment can be maximized.

[0058] In step 30, the finished and cooled tea leaves are subjected to fixation treatment.

[0059] Through fixation treatment, microorganisms in the tea leaves can be effectively removed to prevent spoilage. Fixation treatment can also fix the aroma components of the tea leaves to ensure the quality of the tea leaves. The tea leaves after fixation treatment can become soft and are easier to perform subsequent rolling and other processes.

[0060] In step 40, the fixed tea leaves are conveyed to the discharge box 10 of the discharge mechanism 9.

[0061] The step of conveying the fixed tea leaves to the discharge box of the discharge mechanism can reduce physical damage to the tea leaves during transmission, maintain the integrity of the tea leaves, ensure that the fixed tea leaves can smoothly enter the next process, and avoid accumulation or blockage.

[0062] In step 50, when the fixed tea leaves received by the discharge box 10 reach a preset weight, the fixed tea leaves are released to one of the multiple rolling machines 17.

[0063] According to the preset weight, the fixed tea leaves are distributed, which can ensure that the work load of each rolling machine is uniform, and also can maintain the continuity of the production process and improve the production efficiency.

[0064] In step 60, the fixed tea leaves are subjected to rolling treatment.

[0065] The rolling treatment can help break the cell walls of the tea leaves, promote the outflow of tea juice, facilitate the subsequent fermentation process, and help release the aroma substances in the tea leaves, thereby improving the flavor of the tea. In addition, the rolling treatment allows the tea leaves to form a specific shape, which affects the appearance of the final product. In step 70, the rolled tea leaves are spread out and the tea leaf fragments or impurities smaller than the first size are removed.

[0066] The step of spreading out the rolled tea leaves and removing tea leaf fragments or impurities smaller than the first size can remove small particles and impurities, ensuring the quality of the finished product.

[0067] In step 80, the tea leaves after removing the tea leaf fragments or impurities are shaped.

[0068] The shaping process allows the tea leaves to have a uniform appearance, which is convenient for packaging, transportation, and sales.

[0069] Through the above steps, the entire tea processing process realizes systematic management from spreading, fixation, rolling to shaping, ensuring the quality of the tea leaves and improving the production efficiency. Through the quality control measures at each stage, the quality of the final product is stable. Therefore, the tea production method of the embodiment realizes the primary processing of tea leaves through automatic processes, which can significantly reduce the labor cost of workers, improve the production efficiency and product quality.

[0070] Further, by transporting the spread tea leaves to one of the fixation machines 4 when the spread tea leaves reach the preset weight, and releasing the fixed tea leaves to one of the rolling machines 17 when the fixed tea leaves reach the preset weight, the problems of uneven fixation leaf quantity, resulting in scorched fixation leaves and residual grassy aroma, and uneven rolling leaf filling, resulting in uneven rolling force, increased bitterness of tea leaves, or weak tea flavor, and uneven strips, are avoided.

[0071] Before step 10, the method further includes manually or by any appropriate automated means evenly spreading the picked tea leaves on the spreading rack to complete the off-ground spreading of the tea leaves.

[0072] The step of evenly spreading the picked tea leaves on the spreading rack to complete the off-ground spreading of the tea leaves can help the water in the tea leaves evaporate gradually, thereby reducing the water content in the subsequent processing, which is beneficial for the preservation and processing of the tea leaves. Off-ground spreading can keep the temperature of the tea leaves relatively low, avoiding heat accumulation due to stacking, thereby preventing the tea leaves from deteriorating.

[0073] After step 80, the method further includes evenly spreading the shaped tea leaves on the drying rack to complete drying.

[0074] The shaped tea leaves are evenly spread on the drying rack to complete drying, which can further remove excess water in the tea leaves and help long-term storage of the tea leaves.

[0075] In some embodiments, the feeding box 3 is an automatic weighing feeding box, and the step 20 specifically comprises: stopping the work of the first conveying elevator 18 to stop conveying the completed spread and cooled tea leaves when the completed spread and cooled tea leaves received by the feeding box 3 reach a preset weight; randomly or sequentially selecting an idle standby fixation machine 4; moving the feeding box 3 along the first track 5 to above the fixation machine 4, and completely releasing the completed spread and cooled tea leaves loaded in the feeding box 3 to the fixation machine 4. The preset weight of the feeding box 3 can be the loading capacity of the feeding box 3.

[0076] In some embodiments, the discharging box 10 is an automatic weighing discharging box, and the step 50 specifically comprises:

[0077] stopping the work of the second conveying elevator 19 to stop conveying the fixation tea leaves when the fixation tea leaves received by the discharging box 10 reach a preset weight; randomly or sequentially selecting an idle standby rolling machine 17; moving the discharging box 10 along the second track 5 to above the rolling machine 17, and releasing the fixation tea leaves loaded in the discharging box to the rolling machine 17. The preset weight of the discharging box 10 can be the loading capacity of the discharging box 10.

[0078] In this way, the automatic weighing discharging box can accurately control the weight of the tea leaves, ensure the consistency of the amount of tea leaves entering the rolling machine each time, and thus ensure the consistency of processing and product quality. The automatic stopping of the work of the conveying elevator can realize automatic management without manual intervention, improve the efficiency and reliability of the production line. The random or sequential selection of the idle standby rolling machine can balance the work load between different rolling machines, prevent some machines from being overloaded while other machines are idle, and improve the equipment utilization rate. Moving the discharging box to above the specified rolling machine through the second track makes the layout of the entire production line more flexible, which can adjust the positions of the equipment according to actual needs. Through accurate weight control and orderly equipment scheduling, material waste can be reduced, and production costs can be reduced.

[0079] In some embodiments, the fixation machine 4 is used to perform fixation treatment on the completed spread and cooled tea leaves in the step 30, and the rolling machine 17 is used to perform rolling treatment on the fixation tea leaves in the step 60.

[0080] In some embodiments, the loading capacity of the feeding box 3 matches the single output of the fixation machine 4, and the loading capacity of the discharging box 10 matches the single output of the rolling machine 17. The loading capacity can be flexibly preset according to the quality difference of the spread and cooled tea leaves.

[0081] In some embodiments, after step 60, the method further comprises conveying the rolled tea leaves by the conveyor 11. The conveyor 11 is provided with a plurality of groups of raking rollers to facilitate initial dispersing of the rolled tea leaves carried on the conveyor 11 and to rakingly spread the rolled tea leaves on the conveyor belt.

[0082] The rolled tea leaves can form clumps. The plurality of groups of raking rollers can rakingly spread the rolled tea leaves on the conveyor belt to ensure uniform distribution of the tea leaves during conveying. The uniformly distributed and spread tea leaves facilitate subsequent processes such as drying, screening, etc., thereby ensuring the quality of the tea product.

[0083] In some embodiments, the conveyor belt of the conveyor 11 can have an upward angle relative to the horizontal direction, for example, the angle can be 15 degrees to 60 degrees.

[0084] In some embodiments, in step 70, the rolled tea leaves are dispersed by the de-clumping and screening machine, and tea leaf fragments or impurities smaller than a first size are removed.

[0085] In some embodiments, the de-clumping and screening machine comprises a de-clumping machine 15 and a screening machine 12 provided with a screen 16. The rolled tea leaves are conveyed by the conveyor 11 to the de-clumping machine 15, and are again dispersed by the de-clumping machine 15 and spread on the screen 16. The screening machine 12 is a linear vibrating screen, and the rolled tea leaves move in a straight line on the screen. Thereby, tea leaf fragments or impurities smaller than the first size are removed. The mesh number of the screen can be determined according to the weight of the tea leaves.

[0086] In step 80, the tea leaves after removal of the tea leaf fragments or impurities are shaped by the striping machine 13. The shaped tea leaf strips are straight and uniform, and the tea leaves after striping are uniformly spread on the drying rack to complete off-ground drying of the tea leaves.

[0087] Thus, the tea production method of the present embodiment realizes initial processing of tea leaves through automated processes, which can greatly reduce labor costs of workers, improve production efficiency and product quality.

[0088] In addition, the entire process of the automated process is off-ground operation, and only manual intervention is required in the processes of spreading, loading, and drying. In addition, the entire line of equipment and corresponding process parameters are pre-set by the control system, and no further manual intervention is required.

[0089] In a second aspect, the embodiments of the present application provide a tea production device which can be used to implement the tea production method of the above-mentioned embodiments. As shown in Figures 2-3 The tea production device according to the embodiments of the present application can include a feeding mechanism 2, a plurality of fixation machines 4, a discharging mechanism 9, a plurality of rolling machines 17, a first conveyor 11, a de-clumping and screening machine, and a striping machine 13.

[0090] The feeding mechanism 2 comprises a first conveying elevator 18 configured to receive the tea leaves after completion of the cooling process and to convey the tea leaves to a feeding box 3, and the feeding box 3 is configured to convey the tea leaves to one of the plurality of fixation machines 4 when the received tea leaves reach a preset weight, wherein the one of the fixation machines 4 is a fixation machine selected randomly or in sequence from the plurality of fixation machines and in an idle standby state;

[0091] The plurality of fixation machines 4 are configured to perform fixation processing on the tea leaves after completion of the cooling process;

[0092] The discharging mechanism 9 comprises a second conveying elevator 19 configured to receive the tea leaves after fixation and to convey the tea leaves to a discharging box 10 of the discharging mechanism 9, and the discharging box 10 is configured to release the tea leaves to one of the plurality of rolling machines 17 when the received tea leaves after fixation reach a preset weight, wherein the one of the rolling machines 17 is a rolling machine selected randomly or in sequence from the plurality of rolling machines and in an idle standby state;

[0093] The plurality of rolling machines 17 are configured to perform rolling processing on the tea leaves after fixation;

[0096] The strip forming machine 13 is configured to shape the tea leaves after removal of the tea leaf fragments or impurities.

[0097] Thus, the tea leaf production device of the present embodiment realizes the primary processing of tea leaves through automatic processes, which can greatly reduce the labor cost of workers, improve production efficiency and product quality.

[0098] Further, by conveying the tea leaves after completion of the cooling process to one of the plurality of fixation machines 4 when the tea leaves reach a preset weight, and releasing the tea leaves after fixation to one of the plurality of rolling machines 17 when the tea leaves reach a preset weight, the problems of uneven fixation leaf quantity causing fixation leaves to be scorched, residual grassy smell, and other quality problems, and uneven rolling leaf filling causing uneven rolling force, increased bitterness of tea leaves, weak tea flavor, and uneven strips are avoided.

Specifically, the spread and cooled tea leaves are uniformly fed into the feeding port of the first conveying elevator 18, and the spread and cooled tea leaves are transported into the automatic weighing feeding box by the first conveying elevator 18. When the automatic weighing feeding box is loaded with the spread and cooled tea leaves to reach a preset weight, the first conveying elevator 18 stops working, and the automatic weighing feeding box automatically selects an idle standby state fixation machine. The feeding box transports the spread and cooled tea leaves to above the idle standby fixation machine, and releases the spread and cooled tea leaves into the fixation machine. The automatic weighing feeding box autonomously selects the idle standby fixation machine for discharging according to the system preset.

[0102] In some embodiments, the feeding box 3 is further configured to stop the work of the first conveying elevator 18 when the received spread and cooled tea leaves reach a preset weight, so as to stop conveying the spread and cooled tea leaves; move the feeding box 3 along the first track 5 to above one fixation machine 4, and completely release the spread and cooled tea leaves loaded in the feeding box 3 into the one fixation machine 4, wherein the one fixation machine 4 is an idle standby fixation machine selected at random or in sequence.

[0103] After the fixation machine receives the spread and cooled tea leaves, it will automatically start to complete the fixation of the spread and cooled tea leaves according to the preset process requirements, and automatically output the fixed tea leaves to the cooling conveyor.

[0104] In some embodiments, the fixation machine 4 adopts an electric heating or green fuel combustion heating mode, and various process parameters of the fixation machine 4 can be preset.

[0105] In some embodiments, a plurality of dehumidification devices are installed above the fixation machine 4. Further, dehumidification devices and exhaust systems are installed above the fixation machine 4 to timely remove the water vapor and bad smell generated during fixation.
