[0003] However, in the traditional tea processing, the processes of withering, rolling, deblocking, and tea stripping are all carried out independently, and the withering leaves (tea leaves after withering) and rolling leaves (tea leaves after rolling) are transferred manually.

DETAILED DESCRIPTION

[0043] The present application is further illustrated below through the description of specific implementation methods, but this is not a limitation of the present application. Those skilled in the art can make various modifications or improvements based on the basic ideas of the present application, but as long as they do not deviate from the basic ideas of the present application, they are all within the scope of the present application.

[0044] In a first aspect, an embodiment of the present application provides a method for producing tea leaves, the method comprising steps 10 to 80.

[0045] In step 10 , the tea leaves that have been cooled are placed into the conveyor elevator 18 of the feeding mechanism 2 , and the tea leaves that have been cooled are transported to the feeding box 3 of the feeding mechanism 2 through the conveyor elevator 18 .

[0046] The use of the conveyor elevator 18 improves the automation of the tea processing process, reduces the need for manual operation, and ensures continuous material supply, which helps to maintain the efficient operation of the production line. In addition, through the standardized conveying process, the quality of tea entering the subsequent process can be better controlled.

[0047] In step 20, when the weight of the tea leaves after cooling received by the loading box 3 reaches a preset weight, the tea leaves after cooling are transported to one of the multiple tea-fixing machines 4.

[0048] Batch management according to preset weight ensures that each withering process is carried out under the same conditions, which is conducive to quality consistency. At the same time, different withering machines can be selected according to production needs to improve production flexibility and efficiency. By reasonably allocating tasks to different withering machines, production equipment can be maximized.

[0049] In step 30, the tea leaves that have been cooled are subjected to a withering treatment.

[0050] The withering process can effectively remove microorganisms in tea leaves and prevent them from spoiling. It can also fix the aroma components of tea leaves and ensure the quality of tea leaves. After the withering process, the tea leaves become softer and easier to carry out subsequent processes such as rolling.

[0051] In step 40 , the withered tea leaves are transported to the discharge box 10 of the discharge mechanism 9 .

[0052] The step of conveying the withered tea leaves to the discharge box of the discharge mechanism can reduce the physical damage to the tea leaves during the transmission process, maintain the integrity of the tea leaves, ensure that the withered tea leaves can smoothly enter the next process, and avoid accumulation or blockage.

[0053] In step 50, when the withered tea leaves received by the discharge box 10 reach a preset weight, the withered tea leaves are released to one rolling machine 17 among the plurality of rolling machines.

[0054] Distributing the withered tea leaves according to preset weights ensures that each rolling machine has an even workload, while also maintaining the continuity of the production process and improving production efficiency.

[0055] In step 60, the tea leaves after withering are rolled.

[0056] The rolling process can help break the cell wall of the tea leaves, promote the outflow of tea juice, facilitate the subsequent fermentation process, and can also help release the aromatic substances in the tea leaves and enhance the flavor of the tea. In addition, the rolling process makes the tea leaves form a specific shape, which affects the appearance of the final product. In step 70, the rolled tea leaves are dissolved, and tea leaves fragments or impurities smaller than the first size are removed.

[0057] The steps of dispersing the rolled tea leaves and removing tea leaves fragments or impurities smaller than the first size can remove small particles and impurities to ensure the quality of the finished product.

[0058] In step 80, the tea leaves after removing tea leaves fragments or impurities are formed.

[0059] The forming process gives the tea a uniform appearance, making it easier to package, transport and sell.

[0060] Through the above steps, the entire tea processing process realizes systematic management from cooling, killing green, rolling to forming, ensuring the quality of tea, improving production efficiency, and ensuring the quality stability of the final product through quality control measures at each stage. Therefore, the tea production method of this embodiment realizes the primary processing of tea through an automated process, which can greatly reduce the labor cost of workers and improve production efficiency and product quality.

[0061] Furthermore, when the tea leaves after cooling have reached a preset weight, the tea leaves after cooling are transported to one of the multiple withering machines 4, and when the withered tea leaves reach a preset weight, the withered tea leaves are released to one of the multiple rolling machines 17, thereby avoiding quality problems such as burnt withered leaves, residual grass smell, etc. caused by uneven withering leaf dosage, and uneven rolling force, increased bitterness of the tea leaves, weak tea flavor, and irregular tea leaves due to uneven rolling leaf loading.

[0062] Before step 10, the method further includes: manually or by any appropriate automated means, evenly spreading the picked fresh tea leaves on a cooling rack to complete the cooling of the fresh tea leaves off the ground.

[0063] Spreading the picked fresh tea leaves evenly on the cooling rack to complete the step of cooling the fresh tea leaves off the ground can help the moisture in the fresh tea leaves evaporate gradually, thereby reducing the moisture content in subsequent processing and facilitating the preservation and handling of the tea leaves. Cooling off the ground can keep the temperature of the tea leaves relatively low, avoiding heat accumulation caused by stacking, thereby preventing the tea leaves from deteriorating.

[0064] After step 80, the method further includes: evenly spreading the formed tea leaves on drying racks to complete drying.

[0065] Evenly spreading the formed tea leaves on the drying rack to complete drying can further remove excess moisture from the tea leaves, which helps with the long-term storage of the tea leaves.

[0066] In some embodiments, the loading box 3 is an automatic weighing loading box, and step 20 specifically includes: when the tea leaves that have been cooled received by the loading box 3 reach a preset weight, the conveying elevator 18 is stopped to stop conveying the tea leaves that have been cooled; an idle and waiting withering machine 4 is selected randomly or in sequence; the loading box 3 is moved along the first track 5 to the top of the withering machine 4, and the tea leaves that have been cooled loaded in the loading box 3 are completely released to the withering machine 4.

[0067] The preset weight of the loading box 3 may be the loading capacity of the loading box 3 .

[0068] In some embodiments, the discharge box 10 is an automatic weighing discharge box, and step 50 specifically includes:

[0069] When the weight of the withered tea leaves received by the discharge box 10 reaches a preset weight, the conveyor elevator 9 is stopped to stop conveying the withered tea leaves; an idle rolling machine 17 is selected randomly or in sequence; the discharge box 10 is moved along the second track 5 to the top of the rolling machine 17, and the withered tea leaves loaded in the discharge box are released to the rolling machine 17. The preset weight of the discharge box 10 may be the loading capacity of the discharge box 10.

[0070] In this way, the automatic weighing discharge box can accurately control the weight of the tea leaves, ensuring that the amount of tea leaves entering the rolling machine is consistent each time, thus ensuring the consistency of processing and product quality. Automatically stopping the work of the conveyor elevator can realize automatic management without human intervention, improving the efficiency and reliability of the production line. Randomly or sequentially selecting idle rolling machines can balance the workload between different rolling machines, prevent some machines from being overloaded while others are idle, and improve equipment utilization. By moving the discharge box to the top of the designated rolling machine through the second track, the layout of the entire production line is more flexible, and the equipment position can be adjusted according to actual needs. Through precise weight control and orderly equipment scheduling, material waste can be reduced and production costs can be reduced.

[0071] In some embodiments, in step 30, the tea leaves that have been cooled are subjected to a withering process by a withering machine 4; and in step 60, the withered tea leaves are subjected to a rolling process by a rolling machine 17.

[0072] In some embodiments, the loading capacity of the loading box 3 matches the single output of the fixing 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 tea leaves.

[0073] In some embodiments, after step 60, the method further includes: conveying the rolled tea leaves through a conveyor 11. The conveyor 11 is equipped with multiple sets of raking rollers to facilitate the initial dissolution of the rolled tea leaves that are stuck to each other and carried on the conveyor 11, and to evenly rake the rolled tea leaves onto the conveyor belt.

[0074] Tea leaves may form clumps after rolling. Multiple sets of rake rollers can rake the rolled tea leaves evenly onto the conveyor belt to ensure even distribution of the tea leaves during transportation. Evenly distributed and flat tea leaves help subsequent processes such as drying and screening, thus ensuring the quality of tea products.

[0075] In some embodiments, the conveyor belt of the conveyor 11 may have an ascending angle relative to the horizontal direction, for example, the angle may be 15 degrees to 60 degrees.

[0076] In some embodiments, in step 70, the rolled tea leaves are de-agglomerated by a de-blocking and screening machine, and tea leaves fragments or impurities smaller than the first size are removed.

[0077] In some embodiments, the deblocking and screening machine includes a deblocking machine 15 and a screening machine 12, and the screening machine 12 has a screen 16. The rolled tea leaves are conveyed to the deblocking and screening machine 12 by the conveyor 11, and are spread on the screen 16 after being deblocked again by the deblocking machine 15. The screening machine 12 is a linear vibrating screen, and the rolled tea leaves move along a straight line on the screen. Thus, tea leaves 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.

[0078] In step 80, the tea leaves after the tea fragments or impurities are removed are shaped by the tea stripping machine 13, and the shaped tea strips are straight and even. Finally, the tea leaves after the stripping are evenly spread on the drying rack to complete the off-ground drying of the tea leaves.

[0079] Therefore, the tea production method of this embodiment realizes the primary processing of tea through an automated process, which can greatly reduce the labor cost of workers and improve production efficiency and product quality.

[0080] In addition, the entire automated process is operated off-site, and manual intervention is only required in the cooling, loading and drying processes. In addition, all equipment and corresponding process parameters are preset by the control system, without the need for manual intervention.

[0081] In a second aspect, an embodiment of the present application provides a tea production device, which can be used to implement a tea production method of the above embodiment. Figure 2-Figure 3 As shown, the tea production equipment according to the embodiment of the present application can include a feeding mechanism 2, multiple withering machines 4, a discharging mechanism 9, multiple rolling machines 17, a first conveyor 11, a deblocking and screening machine, and a strip sorting machine 13.

[0089] Therefore, the tea production equipment of this embodiment realizes the primary processing of tea through an automated process, which can greatly reduce the labor cost of workers and improve production efficiency and product quality.

[0090] Furthermore, when the tea leaves after cooling have reached a preset weight, the tea leaves after cooling are transported to one of the multiple withering machines 4, and when the withered tea leaves reach a preset weight, the withered tea leaves are released to one of the multiple rolling machines 17, thereby avoiding quality problems such as burnt withered leaves, residual grass smell, etc. caused by uneven withering leaf dosage, and uneven rolling force, increased bitterness of the tea leaves, weak tea flavor, and irregular tea leaves due to uneven rolling leaf loading.

[0091] In some embodiments, a first track is provided above the multiple tea-fixing machines, preferably directly above them, and the loading box 3 can move along the first track; the loading box 3 transports the cooled tea leaves to the top of the tea-fixing machine 4 along the first track, and releases the cooled tea leaves to the tea-fixing machine 4.

Specifically, the cooling leaves are evenly fed into the feeding port of the conveyor elevator 18, and the cooling leaves are transported to the automatic weighing loading box through the conveyor elevator 18. When the automatic weighing loading box is loaded with cooling leaves and reaches a preset weight, the conveyor elevator 18 stops working, and the automatic weighing loading box automatically selects an idle standby fixing machine. The loading box transports the cooling leaves along the track to just above the idle standby fixing machine, and releases the loaded cooling leaves into the fixing machine. Among them, the automatic weighing loading box autonomously selects an idle standby fixing machine for unloading according to the system preset.

[0095] After receiving the cooling leaves, the withering machine will automatically start to complete the withering of the cooling leaves according to the preset process requirements, and automatically output the withered tea leaves to the cooling conveyor.

[0096] In some embodiments, the withering machine 4 adopts electric energy heating or burning green fuel heating, and various process parameters of the withering machine 4 can be preset.

[0097] In some embodiments, multiple groups of dehumidification devices are installed above the fixing machine 4. Further, a dehumidification device and an exhaust system are installed above the fixing machine 4 to timely remove the water vapor and bad smell generated during the fixing process.

[0098] In some embodiments, the discharging mechanism 9 further includes: a second conveyor 6, which is located below the outlets of the plurality of tea-fixing machines and is used to convey the tea leaves after fixing to the conveyor elevator 19.

[0099] In some embodiments, the second conveyor 6 is a cooling conveyor. The cooling conveyor is equipped with a plurality of cooling fans 8 and rake rollers 72. The cooling fans continuously cool down the tea leaves after withering, and the rake rollers rake the tea leaves after withering and spread them evenly on the conveyor.

After the withered tea leaves are loaded to a preset weight, the automatic weighing discharge box moves to the top of the rolling machine along the track located above the rolling machine, and releases the withered tea leaves into the rolling machine.

[0109] The screening machine 12 uses a linear vibrating screen to make the rolled tea leaves move in a straight line on the screen, thereby removing tea leaves fragments or impurities smaller than the first size. The discharge port of the screening machine 12 is connected with the feed port of the stripping machine 13, that is, the rolled tea leaves continue to be transported forward by the stripping machine, and the rolled tea leaves are shaped in the process of passing through, so that the tea leaves are straight and even.

After the cooling leaves are fixed according to the preset process requirements, the fixed tea leaves are conveyed to the rolling machine 17 by the discharging mechanism 9.

After the rolling process is completed, the rolled tea leaves will be released onto the conveyor 11 located below the rolling machine 17. The multiple groups of rake rollers 71 installed on the conveyor 11 will loosen the rolled tea leaves that are stuck to each other and spread them on the conveyor 11. Thereafter, the rolled tea leaves are conveyed to the deblocking machine 15 via the conveyor 11, loosened again by the deblocking machine 15 and spread on the screen 16 of the screening and crushing machine. The rolled tea leaves are further transported forward by the screen 16 to the stripping machine 13 to remove the debris, and then the rolled tea leaves are further transported forward by the stripping machine 13. The rolled tea leaves are shaped during the passage of the stripping machine 13, so that the tea strips are straight and even. Finally, the tea leaves that have been stripped are evenly spread on the drying rack manually to complete the drying of the tea leaves off the ground.

[0114] Compared with the prior art, the various embodiments of the present application have the following advantages and positive effects:

[0115] 1) The whole process of tea primary processing is operated off-ground and fully automated. Through the preset of the control system, standardized production is achieved, which effectively improves production efficiency and produces tea with uniform and stable quality.

[0116] 2) There are multiple withering machines and rolling machines in a parallel distributed layout. Multiple withering machines and rolling machines work intermittently as a single machine, but the production equipment is for continuous production, that is, the production arrangement is more flexible, and the production line production is no longer limited by the amount of raw materials.

[0117] 3) The tea leaves after cooling and the tea leaves after withering are automatically weighed and quantitatively fed by the feeding mechanism and the discharging mechanism, that is, the withering and rolling of the tea leaves are more uniform and stable, and the production process is smoother and more efficient.

[0118] 4) The tea leaves are handled off the ground during the entire production process. The tea withering machine uses electric heating or burning green fuel for heating, which greatly reduces the chance of tea contamination during production, realizes fully automatic and clean production of tea, and further consolidates and implements the concept of green production.

[0119] 5) The number of withering machines and rolling machines can be flexibly configured without being restricted by factors such as production scale and site space. That is, this process and system have strong applicability and scalability.

[0120] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present application, but the present application is not limited thereto.
