Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, specifically to a tea rehumidification machine. Background Technology

[0002] Tea rehumidification machines are key equipment in tea processing, mainly used to adjust the moisture content of tea leaves, improve quality, and increase processing efficiency.

[0003] Application No. 2023230246255 discloses a tea rehumidification machine, comprising a tunnel-type shell and an S-shaped multi-layer belt conveyor. The tunnel-type shell has a feed inlet at the top of one end and a discharge outlet at the top of the other end. The other end of the tunnel-type shell has a conical air inlet, wider at the inside and narrower at the outside. A cool air fan is located outside the conical air inlet to blow humidified cool air into the tunnel-type shell. The rehumidification machine is used to cool the tea leaves after processing (killing the green) and replenish their moisture. This invention can blow humidified cool air into the rehumidification machine, which helps the tea leaves quickly regain their moisture after killing the green, making them softer and easier for subsequent rolling or shaping processes. This reduces the breakage rate of the tea leaves, improves their integrity, and ensures the rehumidification effect. Furthermore, by adjusting the speed of the cool air fan, the humidity of the cool air and the temperature of the tea leaves can be adjusted, allowing the tea leaves to achieve different rehumidification effects.

[0004] While the above technical solutions can solve the problem of restoring moisture to tea leaves, they have the following problems: 1. Complex structure and high manufacturing cost; 2. Poor stability, especially for layered belt conveyors, which have poor reliability when operating in high humidity environments. Utility Model Content

[0005] This utility model proposes a tea rehumidification machine, which solves the problems of complex structure, high manufacturing cost and poor stability of existing tea rehumidification machines.

[0006] The technical solution of this utility model is as follows: a tea rehumidification machine, comprising a housing, the housing being composed of a storage plate, a square tube frame, a rear storage door, and a front storage door; and further comprising a tea transfer cart and a humid air circulation assembly. The tea transfer cart is composed of an upper transfer unit, a lower transfer unit, a tray, and casters. The upper and lower transfer units are rectangular tubular structures with openings at both ends, and tray supports are evenly fixed on the inner walls. The tray supports hold the trays. The lower transfer unit has casters at its bottom. The humid air circulation assembly is composed of an air inlet, an ultrasonic humidifier, a turbine fan, a motor, a diffuser A, an exhaust port, and a diffuser B. The air inlet has an ultrasonic humidifier in the middle, and a turbine fan is connected to the end of the air inlet. The turbine fan is driven by a motor. Several diffuser A are horizontally installed at the front end of the air inlet, and an exhaust port is located below the air inlet. Several diffuser B are horizontally installed at the front end. The air inlet and exhaust port are fixed to the front storage door.

[0007] Preferably, the spacing between the trays is the same as the spacing of the diffuser baffle A at the front end of the air inlet.

[0008] Preferably, the rear compartment door and the front compartment door are hinged to the compartment panels.

[0009] Preferably, the rear and front compartment doors have sealing strips at the points where they meet the compartment panels.

[0010] Preferably, there is a partition between the upper transfer unit and the lower transfer unit.

[0011] Preferably, the upper transfer unit, lower transfer unit, and pallet are made of stainless steel sheet.

[0012] Preferably, the rear compartment door has a control panel, the top of the compartment panel has an alarm, and the box contains a humidity sensor.

[0013] Preferably, the storage panels, rear storage door, and front storage door are made of foam-core color steel panels.

[0014] Preferably, the bottom of the inner wall of the box has guide wheels.

[0015] Preferably, the air inlet and exhaust outlet are funnel-shaped.

[0016] The principle of this utility model: To solve the problems of complex structure, high manufacturing cost, and poor stability of existing tea rehumidification machines, this utility model uses a tea transfer cart to replace the existing layered belt conveyor, simplifying the structure of the tea rehumidification machine, reducing maintenance difficulty, and lowering the purchase and use costs. The tea transfer cart consists of an upper transfer unit and a lower transfer unit, both of which are rectangular tubular structures with several parallel pallet supports on their inner walls. Several pallets are placed on the pallet supports, and the tea to be processed is placed in the pallets. The length of the upper and lower transfer units can be adjusted according to the scale of tea processing in the enterprise. The lower transfer unit has casters at the bottom, making it easy for production personnel to push the tea transfer cart into the box. To improve production efficiency, two or more tea transfer carts are configured. One enters the box for rehumidification, while the other loads tea for rehumidification, and the cycle repeats, improving production efficiency. This utility model rehumidifies... The humidified air is generated by an ultrasonic humidifier. Ultrasonic humidifiers have high humidification intensity, producing small and uniform mist particles that can quickly reach the required relative humidity within a unit of time. The technology is mature, and mature products can be purchased from the market. The generated humidified air is blown into the chamber by a turbine fan. The upper transfer unit of the tea transfer cart is aligned with the air inlet, and the humidified air passes through the gaps between the trays, evenly humidifying the tea in the trays and accelerating the recovery of moisture, causing the tea to soften. After passing through the upper transfer unit, the humidified air turns around and enters the lower transfer unit, passing through the gaps between the trays again to humidify the tea in the lower transfer unit, and finally exits from the exhaust port. After the tea re-humidification process is completed, the ultrasonic humidifier and motor are turned off, the rear and front doors are opened, and the tea transfer cart is pushed out of the chamber. Then, tea to be re-humidified is pushed in again. This process is repeated to complete the tea re-humidification process. Compared with existing layered belt conveyors, the tea re-humidification is more uniform.

[0017] The beneficial effects of this utility model are as follows: A tea rehumidification machine has a scientific and reasonable structure, low manufacturing cost, easy maintenance, convenient operation, safety and reliability, high work efficiency, uniform tea rehumidification, and good quality.

Detailed Implementation

[0028] The specific implementation method of this utility model is as follows: Figures 1-9As shown, a tea rehumidification machine includes a housing 100, which is composed of a storage plate 101, a square tube frame 102, a rear door 103, and a front door 104. It also includes a tea transfer cart 200 and a humid air circulation assembly 300. The tea transfer cart 200 consists of an upper transfer unit 201, a lower transfer unit 202, a tray 204, and casters 205. The upper transfer unit 201 and the lower transfer unit 202 are rectangular tubular structures open at both ends, with tray supports 203 evenly fixed to their inner walls. The trays 204 are placed on the tray supports 203. The lower transfer unit 202 has casters 205 at its bottom. The humid air circulation assembly... Component 300 comprises an air inlet 301, an ultrasonic humidifier 302, a turbine fan 303, a motor 304, a diffuser plate A305, an exhaust port 306, and a diffuser plate B307. The ultrasonic humidifier 302 is located in the middle of the air inlet 301, and the turbine fan 303 is connected to the end of the air inlet 301. The turbine fan 303 is driven by the motor 304. Several diffuser plates A305 are horizontally installed at the front end of the air inlet 301, and the exhaust port 306 is located below the air inlet 301. Several diffuser plates B307 are horizontally installed at the front end. The air inlet 301 and the exhaust port 306 are fixed to the front compartment door 104. In this embodiment, the ultrasonic humidifier 302, turbine fan 303, and motor 304 are existing technologies and mature products can be purchased from the market. The ultrasonic humidifier 302 can be modified for automatic water filling. During the tea rehydration process, pure water is continuously injected into the ultrasonic humidifier 302 to ensure continuous operation. The housing 100 consists of left, right, and top compartments 101, a rear door 103, and a front door 104. The bottom compartment 101 is replaced by a cement floor to ensure a flat surface. The exhaust port 306 ends with a dehumidification window 308. When the turbine fan 303 stops working, the dehumidification window 308 is closed, using unidirectional positive pressure exhaust. To ensure that the turbine fan 303 draws in clean air, a filter element can be installed at the front end of the turbine fan 303 to filter dust and impurities in the outside air, preventing the tea from being contaminated. When the ambient humidity is high, the operating parameters of the ultrasonic humidifier 302 and turbine fan 303 should be adjusted to prevent the tea from becoming excessively moist, which would affect subsequent processing.

[0029] Specifically, such as Figure 9 As shown, the spacing between the trays 204 is the same as the spacing of the diffuser baffle A305 at the front end of the air inlet 301. In this embodiment, by adopting the above technical solution, it can be ensured that humid air passes through the trays 204 evenly, thereby improving the efficiency and quality of tea rehydration.

[0030] Specifically, such as Figure 4 As shown, the rear compartment door 103 and the front compartment door 104 are hinged to the compartment panel 101. In this embodiment, when loading and unloading tea, the operator only needs to open the rear compartment door 103 and the front compartment door 104, which is convenient to use.

[0031] Specifically, the rear door 103 and the front door 104 are fitted with sealing strips at the points where they meet the storage plate 101. In this embodiment, the sealing strips provide good sealing performance, preventing humid air from escaping and affecting the quality of tea rehydration, and also preventing outside air from entering the box 100 and affecting the quality of tea rehydration.

[0032] Specifically, such as Figure 6 , Figure 7 As shown, there is a partition between the upper transfer unit 201 and the lower transfer unit 202. In this example, the partition divides the movement path of the humid air, allowing it to pass through the trays 204 of the upper transfer unit 201 and the lower transfer unit 202 in sequence, so that the tea leaves in the trays 204 are moistened in a sequential manner.

[0033] Specifically, the upper transfer unit 201, lower transfer unit 202, and pallet 204 are made of stainless steel. In this embodiment, the stainless steel upper transfer unit 201, lower transfer unit 202, and pallet 204 are not easily corroded in high humidity environments, have a long service life, and prevent tea from being contaminated.

[0034] Specifically, such as Figure 3 As shown, the rear door 103 has a control panel (not shown in the figure), the top of the compartment 101 has an alarm 106, and the housing 100 contains a humidity sensor. This embodiment provides an automated modification route. The control panel adjusts rehumidification parameters, such as the humidification intensity of the ultrasonic humidifier 302, the blowing intensity of the turbine fan 303, and the rehumidification operation duration. The humidity sensor provides feedback on the humidity parameters of the housing 100, and the alarm 106 provides an audible and visual alarm, prompting production personnel to closely monitor the rehumidification operation information.

[0035] Specifically, the storage panel 101, rear door 103, and front door 104 are made of foam-core corrugated steel sheet. In this embodiment, the storage panel 101, rear door 103, and front door 104 made of foam-core corrugated steel sheet have good thermal insulation performance, preventing the tea re-moistening process from being affected by the external environment. Furthermore, the materials are readily available, the procurement cost is low, and the installation is simple, allowing for quick completion of the box 100 installation.

[0036] Specifically, such as Figure 9 As shown, the bottom of the inner wall of the box 100 has guide wheels 105. In this embodiment, the guide wheels 105 are attached to the outer wall of the lower transfer unit 202 to provide auxiliary positioning, making it convenient for production personnel to push the tea transfer cart 200 into the box 100.

[0037] Specifically, such as Figure 2 , Figure 5As shown, the air inlet 301 and the exhaust outlet 306 are funnel-shaped. In this embodiment, the funnel-shaped air inlet 301 and exhaust outlet 306 facilitate the diffusion of humid air, ensuring that the humid air can diffuse rapidly between the upper transfer unit 201 and the lower transfer unit 202.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
