Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a withering trough for tea processing with adjustable temperature. Background Technique

[0002] A withering trough for tea processing with adjustable temperature can accurately control the temperature during the withering process, ensure uniform withering of tea leaves, enhance aroma and quality, shorten the processing time, and save energy. By adjusting the temperature, it can meet the processing requirements of different types of tea leaves, improving production efficiency and consistency.

[0003] The existing withering trough is not provided with an upper cover plate, resulting in the hot air directly diffusing into the air after passing through the tea leaves, reducing the utilization rate of heat energy. Moreover, without an upper cover plate, the temperature change in the external environment will affect the temperature inside the withering trough, causing large fluctuations in the internal temperature of the withering trough.

[0004] Large fluctuations in the internal temperature of the withering trough will lead to uneven withering of tea leaves, affecting the color, aroma and taste of the tea leaves, and may cause some tea leaves to be over-withered or under-withered, thus reducing the overall quality of the tea leaves. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a withering trough for tea processing with adjustable temperature to solve the problems put forward in the above background technique.

The hot drying air can accelerate the evaporation of moisture in the tea leaves, improve the withering speed, shorten the withering time, and enhance the production efficiency.

[0009] As a preferred embodiment, the two partition plates divide the drying box into two equal parts. One is the drying area near the air inlet pipe, and the other is the heating area containing the first electric heater. The partition plates can separate the drying area and the heating area to avoid mutual influence between the two areas.

[0010] As a preferred embodiment, the power mechanism includes a motor. The motor is fixedly installed on the outer surface of the rotating shaft. The motor is arranged on the outer surface of the hot air duct. The motor can provide power for the rotating shaft.

[0013] As a preferred embodiment, a plurality of air inlet holes are formed at the bottom of the withering tank. A second electric heater is fixedly connected to the inner surface of the hot air duct. The second electric heater can heat the dried air.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0015] 1. The present utility model can control the air volume through a valve, enabling more precise temperature regulation, ensuring that the temperature in the withering trough is more uniform and stable. At the same time, the hot air that has done work is conveyed into the air inlet pipe to increase the initial temperature of the air, improving the utilization rate of thermal energy. Meanwhile, after the conical cover plate is closed, the internal heat is not easily dissipated, forming a relatively stable microenvironment, so that the tea leaves are heated more evenly during the withering process, which is beneficial to the uniform withering of the tea leaves.

[0016] 2. The utility model utilizes dry hot air to accelerate the evaporation of moisture in tea leaves, improve the withering speed, shorten the withering time, and enhance the production efficiency. At the same time, the dry hot air creates a dry environment for tea leaf withering. The dry environment can reduce the chance of mold growth and prevent the tea leaves from mildewing and deteriorating during the withering process, ensuring the safety and hygienic quality of the tea leaves.

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a withering trough for tea processing with adjustable temperature, including: a workbench 1, the inner surface of the workbench 1 is fixedly connected with a withering pool 2, the bottom of the withering pool 2 is fixedly connected with a conical hopper 4, the bottom of the conical hopper 4 is fixedly connected with a hot air pipeline 5, the outer surface of the hot air pipeline 5 is fixedly connected with a drying box 6, the outer surface of the drying box 6 is fixedly connected with an air inlet pipe 7, the withering pool 2 is provided with a conical cover plate 3 through a hinge, the top of the conical cover plate 3 is fixedly connected with a connecting hose 10, the connecting hose 10 is fixedly connected to the outer surface of the air inlet pipe 7, a check valve 9 is arranged on one side of the connecting hose 10 close to the air inlet pipe 7, and a valve 8 is arranged on one side of the air inlet pipe 7 close to the drying box 6;

[0027] An air drying mechanism is arranged inside the drying box 6. After the conical cover plate 3 is closed, the heat inside is not easy to dissipate, forming a relatively stable microenvironment, so that the tea is heated more evenly during the withering process, which is beneficial to the uniform withering of the tea. At the same time, the hot air that has done work is transported into the air inlet pipe 7, increasing the initial temperature of the air and improving the utilization rate of thermal energy.

[0028] As Figures 1-6 shown, the drying mechanism includes a drying wheel 16, the inner surface of the drying wheel 16 is fixedly installed with a rotating shaft 13, the rotating shaft 13 is movably embedded in the inner surface of the drying box 6, both sides of the rotating shaft 13 close to the drying wheel 16 are movably sleeved with partition plates 14, the two partition plates 14 are fixedly connected to the inner wall of the drying box 6, two electric heaters I 17 are fixedly connected to the inner wall of the drying box 6, a plurality of air guide pipes 18 are fixedly connected to the outer surface of the drying box 6, a power mechanism is fixedly installed on the outer surface of the rotating shaft 13, and the dried hot air can accelerate the evaporation of water in the tea, improve the withering speed, shorten the withering time, and improve the production efficiency. At the same time, the dried hot air creates a dry environment for tea withering. The dry environment can reduce the chance of mold growth and prevent the tea from mildewing and deteriorating during the withering process, ensuring the safety and hygienic quality of the tea.

[0029] As Figures 1-6 shown, the two partition plates 14 divide the drying box 6 into two equal parts on average. One is the drying area close to the air inlet pipe 7, and the other is the heating area containing the electric heaters I 17. The partition plates 14 can separate the drying area and the heating area to avoid the mutual influence of the two areas and affect the stable operation of the equipment.

[0030] As Figures 1-6 shown, the power mechanism includes a motor 15, the motor 15 is fixedly installed on the outer surface of the rotating shaft 13, the motor 15 is arranged on the outer surface of the hot air pipeline 5, and the motor 15 can provide power for the rotating shaft 13 to make the rotating shaft 13 rotate.

[0031] As Figures 1-6As shown, a plurality of pores are evenly formed on the outer surface of the drying wheel 16, and silica gel is filled inside the pores. The silica gel can absorb moisture in the air to dry the air and provide dry air for the equipment.

[0032] As Figures 1-6 shown, a connecting plate 19 is fixedly connected to the top of the drying box 6, and the connecting plate 19 is fixedly connected to the bottom of the workbench 1. A handle 20 is fixedly connected to the outer surface of the conical cover plate 3. The handle 20 can facilitate the opening of the conical cover plate 3 for the convenience of users.

[0033] As Figures 1-6 shown, a plurality of air inlets 11 are formed at the bottom of the withering tank 2. An electric heater II 12 is fixedly connected to the inner surface of the hot air duct 5. The electric heater II 12 can heat the dry air to provide dry hot air for the equipment.

[0034] Working principle: This equipment is a withering trough for tea processing with adjustable temperature. The connecting plate 19 can fix the drying box 6, the workbench 1 can support the withering tank 2, and the valve 8 is driven by a motor and can freely control the opening degree of the valve 8. When in use, the conical cover plate 3 is opened by using the handle 20, then the tea leaves are introduced into the withering tank 2 and the conical cover plate 3 is covered, and then the electric heater II 12 is powered on to make the electric heater II 12 release heat.

[0035] Then the motor 15 is started. The motor 15 drives the rotating shaft 13 inside the partition plate 14 to rotate through the output shaft. The rotating shaft 13 drives the drying wheel 16 to rotate. Then the valve 8 is opened, and the air inlet pipe 7 is connected to the outlet pipe of the induced draft fan. The induced draft fan is started to make the air enter the air inlet pipe 7, and then the air enters the drying box 6. The silica gel in the pores on the drying wheel 16 can absorb moisture in the air to dry the air. The silica gel that has absorbed moisture will rotate to the heating area as the drying wheel 16 rotates. The power supply of the electric heater I 17 is turned on, and the electric heater I 17 releases heat to heat the silica gel that has absorbed moisture, so that the water in the silica gel is separated out and forms steam. The steam will be discharged through the air guide pipe 18, so that the silica gel can absorb moisture in the air again.

[0036] The dry air enters the hot air duct 5, takes away the heat released by the electric heater II 12, and the heated dry air then enters the conical hopper 4, and then enters the inside of the withering tank 2 through the air inlets 11 to heat the tea leaves and provide heat for the withering of the tea leaves. The hot air that has heated the tea leaves enters the inside of the conical cover plate 3, then enters the inside of the connecting hose 10, and finally returns to the air inlet pipe 7 through the one-way valve 9. The hot air preliminarily heats the unheated air, improves the initial temperature of the air, and improves the utilization rate of thermal energy.

[0037] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
