Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a batch processing tea withering machine. Background Technology

[0002] Tea is a general term for the buds and leaves of the tea plant, as well as processed bud and leaf products. The tea plant is a dicotyledonous plant, and its leaves are processed into tea leaves, which can be brewed directly with boiling water. Tea contains rich nutrients, such as theophylline, catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, which have various health benefits for the human body.

[0003] Freshly picked leaves have a high water content, and their cell tissues are in a tense state, making them hard and brittle. This makes them difficult to roll and shape into a good tea leaf shape. Furthermore, the tea juice is easily lost during rolling, which is not conducive to the normal transformation of the internal substances. By withering the tea leaves, the process of reducing the moisture content of the fresh leaves can be utilized to promote a slow and orderly change in the shape and internal components of the tea leaves, thereby laying the foundation for the unique quality of each type of tea.

[0004] However, existing technologies require hot air to be blown onto each tea withering rack, necessitating multiple hot air ducts for air supply and processing tea leaves on different racks in batches, resulting in low overall processing efficiency. Therefore, a batch processing tea withering machine is proposed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a batch processing tea withering machine, which aims to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A batch processing tea withering machine includes a housing, and an exhaust pipe with a pressure relief valve is installed on the top of the housing. The machine is characterized by further comprising:

[0008] The air supply structure is fixed inside the shell, with the air inlet extending to the outside of the shell. The air supply structure delivers hot air to the inside of the shell.

[0009] The laying rack is located within the air supply structure and is slidably connected to the inside of the housing;

[0010] The deflector plates are respectively installed on the underside of each laying rack and fixed to the inner wall of the shell at both ends to receive the water flowing out of the laying rack.

[0011] The water tank, which is fixed to the outer end of the shell away from the laying frame, receives the water discharged from the deflector plate.

[0012] Preferably, the laying rack further includes:

[0013] The outer frame is slidably connected to the inside of the housing, allowing it to be slidably removed or placed inside the housing.

[0014] A breathable mesh is placed at the bottom of the outer frame to allow moisture from the tea leaves to escape from the bottom of the frame.

[0015] The baffle is fixed to one side of the outer end of the outer frame, with the side away from the ventilation mesh located on the outside of the shell, and is equipped with a handle.

[0016] Preferably, the air supply structure further includes:

[0017] The air supply panel is designed in a corrugated shape, with each groove of the air supply panel corresponding to a laying rack;

[0018] Several sets of air outlet pipes correspond one-to-one with several laying racks. Each set of air outlet pipes includes several air outlet pipes that are connected and fixed to the air supply plate and are located above the corresponding outer frame. They can evenly spray the hot air in the air supply plate onto the corresponding laying rack.

[0019] Preferably, the guide plate is inclined so that the water received by the guide plate can flow towards the side closer to the water tank.

[0020] Preferably, the water tank has a drain pipe with a built-in valve on one side of its bottom.

[0021] Preferably, the outer end of the outer frame is provided with limit strips on both sides perpendicular to the baffle. The lower side of the limit strip is equipped with a bracket that is fixed to the inner wall of the shell at both ends. When the laying rack is inside the shell, the bracket supports the two sides of the laying rack.

[0022] The bracket has several rollers rotatably mounted on one end near the corresponding outer frame. When the laying rack is inside the housing, the rollers are in contact with the limiting strip and the bracket respectively, reducing friction during the sliding process of the laying rack.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] This utility model provides a batch processing tea withering machine that only needs to supply hot air through a single air duct in the air supply structure. The air supply structure includes an air supply plate and several sets of air outlet pipes. The air supply plate is set in a wave shape to transport the hot air. The air outlet pipes spray the hot air in the air supply plate evenly onto the corresponding laying rack. With this structure, tea leaves in multiple laying racks can be withered in batches at the same time, which improves the processing efficiency.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The embodiments proposed in this application are as follows: A batch processing tea withering machine includes a housing 10, which is supported by a support block at its bottom to prevent the housing 10 from directly contacting the ground. The housing 10 is provided with an air supply structure 20 and several laying racks 30. The air supply structure 20 is fixed inside the housing 10 and supplies hot air to the inside of the housing 10. The air supply structure 20 is provided with several laying racks 30, which are slidably connected to the inside of the housing 10 for laying the tea leaves to be processed. An exhaust pipe 11 is installed on the top of the housing 10 and communicates with its interior. The exhaust pipe 11 has a built-in pressure relief valve to prevent the internal air pressure of the housing 10 from becoming too high due to high temperature and causing a safety accident.

[0035] The laying rack 30 is designed as a drawer, which facilitates its removal and placement within the housing 10. The laying rack 30 includes an outer frame 31 that is slidably connected to the inside of the housing 10. The bottom of the outer frame 31 is provided with a breathable mesh 32, which allows moisture from the tea leaves to seep out due to high temperatures, preventing it from accumulating at the bottom of the outer frame 31. A baffle 33 is fixed to one side of the outer end of the outer frame 31. The length and height of the baffle 33 are slightly greater than the length and height of the corresponding outer frame 31. The side of the baffle 33 away from the breathable mesh 32 is located on the outside of the housing 10 and is equipped with a handle for easy pulling by staff. The laying rack 30 can be slidably removed and placed within the housing 10 by pulling the handle.

[0036] The air inlet of the air supply structure 20 extends to the outside of the housing 10. The air supply structure 20 includes an air supply plate 21 and several sets of air outlet pipes 22. The air supply plate 21 is located inside the housing 10 and is fixed to the inner wall of the housing 10 by mounting plates 211 on both sides. The air supply plate 21 is wavy. Each groove of the air supply plate 21 corresponds to a laying rack 30. The number of sets of air outlet pipes 22 corresponds one-to-one with the number of laying racks 30. Each set of air outlet pipes 22 includes several air outlet pipes 22 that are connected and fixed to the air supply plate 21 and are located above the corresponding outer frame 31. This allows each set of air outlet pipes 22 to evenly spray the hot air in the air supply plate 21 onto the corresponding laying rack 30 to heat and wither the tea leaves. With this structure, the air supply structure 20 only needs to be used as a single air duct to supply hot air and to process the tea leaves in multiple laying racks 30 in batches, thus improving processing efficiency.

[0037] The air supply structure 20 supplies hot air through the air supply device, and a dehumidification device is also installed inside the housing 10. A controller 12 is installed on the outer end of the housing 10 corresponding to the air inlet end of the air supply structure 20. The air supply device and the dehumidification device are both connected to the exhaust pipe 11. The air supply device, dehumidification device and exhaust pipe 11 can all be existing devices, and the installation can be carried out according to the specific situation. Corresponding temperature sensors and humidity sensors are installed inside the housing 10. The exhaust pipe 11 is the control panel of the built-in PLC control system. The humidity and temperature data detected by the temperature and humidity sensors are transmitted to the control panel. The operator adjusts the temperature, humidity and processing time inside the housing 10 based on the detected data. This section is a general overview of the commonly used control methods and functions of the withering machine, so it will not be described in detail.

[0038] See Figure 2 , Figure 3 and Figure 5Each laying rack 30 has a corresponding guide plate 40 on its lower side. The guide plate 40 is fixed to the inner wall of the housing 10 through its two ends. The guide plate 40 can receive the water flowing out of the upper laying rack 30 at the corresponding position. The guide plate 40 is inclined. A water tank 50 is fixed on the outer end of the housing 10 away from the laying rack 30. The guide plate 40 is connected to the water tank 50. The passage at the connection is inclined so that the water received by the guide plate 40 flows to the side closer to the water tank 50 and is discharged into the water tank 50. A discharge pipe with a built-in valve is provided on one side of the bottom of the water tank 50. The water entering the water tank 50 can be discharged through the discharge pipe.

[0039] Further details can be found here. Figure 2 , Figure 5 and Figure 6 Limiting strips 311 are respectively provided on the two sides of the outer end of the outer frame 31 perpendicular to the baffle 33. The lower side of the limiting strips 311 is equipped with brackets 60 whose two ends are fixed to the inner wall of the housing 10. Each outer frame 31 corresponds to two brackets 60. When the laying rack 30 is inside the housing 10, the two sides of the laying rack 30 are supported by the brackets 60. Several rollers 61 are rotatably provided on one end of the bracket near the corresponding outer frame 31. When the laying rack 30 is inside the housing 10, the rollers 61 are in contact with the limiting strips 311 and the brackets 60 respectively, so that the laying rack 30 can be slidably picked up and put down during the process. The limiting strips 311 can drive the rollers 61 to rotate on the brackets 60, reducing the friction of the laying rack 30 during the sliding process, and making it easier to pick up and put down the laying rack 30. Through this structure, the support of the laying rack 30 can be improved while the friction of the laying rack 30 during the sliding process can be reduced.
