Description

Technical Field

[0001] This utility model relates to the field of tea production technology, specifically to a tea fixation machine with adjustable temperature. Background Technology

[0002] Fixing (or killing the green) is one of the initial processing steps for green tea, yellow tea, black tea, oolong tea, and other teas. Fixing involves using high temperatures to destroy and deactivate the oxidase activity in fresh tea leaves, inhibiting the enzymatic oxidation of tea polyphenols and other substances in the fresh leaves, evaporating some of the moisture from the fresh leaves, softening the tea leaves, making them easier to roll and shape, and at the same time removing the grassy smell and promoting the formation of a good aroma. Therefore, it is necessary to design a tea fixing machine with adjustable temperature.

[0003] Most existing temperature-adjustable tea fixing machines lack internal moisture removal mechanisms, causing moisture generated during tea fixing to accumulate inside the drum. When the drum is opened later, this moisture liquefies upon cooling and adheres to the surface of the fixed tea leaves, affecting their quality. Furthermore, most existing temperature-adjustable tea fixing machines lack internal cooling mechanisms, requiring the fixed tea leaves to be removed and cooled in a cooling machine for color fixation. This process is cumbersome and reduces the versatility of the tea fixing machine. Utility Model Content

[0004] The purpose of this utility model is to provide a tea fixing machine with adjustable temperature, which solves the problem that most traditional tea fixing machines with adjustable temperature do not have a moisture removal mechanism inside, so when the moisture liquefies later, it will adhere to the surface of the tea leaves and affect the quality of the tea fixing. At the same time, it also solves the problem of the cooling step that needs to be taken out of the cooling machine after the tea is fixed, which increases the versatility of the tea fixing machine.

[0006] According to the temperature-adjustable tea fixation machine described above, the water vapor removal component includes a first air pump, a cooling chamber, a semiconductor refrigeration sheet, and an L-shaped connecting pipe. The cooling chamber is installed at the middle position on the top of the outer cylinder. An air cooling component is provided at the bottom inside the cooling chamber.

The L-shaped connecting pipe is installed at the top of the cooling chamber near the temperature sensing mechanism, and the bottom of the L-shaped connecting pipe is connected to the top of the aluminum heat conduction pipe. The first air pump is installed at the bottom of the cooling chamber on the side away from the L-shaped connecting pipe, and the input end and the output end of the first air pump are respectively communicated with the top inside the outer cylinder and the top on the other side inside the cooling chamber.

[0007] According to the temperature-adjustable tea fixation machine described above, the air cooling component includes a connecting pipe, an input pipe, an output pipe, and a second air pump. The second air pump is installed on the side of the bottom of the outer cylinder away from the toothed disk, and the output end of the second air pump is communicated with the bottom inside the outer cylinder.

[0009] According to the temperature-adjustable tea fixation machine described above, ball grooves are evenly provided at the edges on both sides inside the outer cylinder, and balls that fit the outside of the inner net cylinder are engaged inside multiple groups of ball grooves.

[0010] According to the temperature-adjustable tea fixation machine described above, the connecting pipe is made of a continuous "zigzag" structure and is integrally installed in an arc shape at the bottom inside the cooling chamber.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1.

Finally, with the structural design of the input pipe, connecting pipe, output pipe and air pump II, the cooling can also be drawn into the interior of the outer cylinder to cool and fix the tea leaves inside the inner mesh cylinder after the initial processing. This increases the multi-functionality of the tea processing machine in later use and realizes the integrated structural design of tea processing and cooling. There is no need to take the tea leaves out and put them into the cooling machine for cooling later, which further increases the practicality and convenience of the tea processing machine.

A temperature sensing mechanism 7 is installed on the top of the outer cylinder 1 near the motor 8. The design of the spiral heating pipe 11 can realize the high-temperature blanching operation of the tea leaves inside the inner mesh cylinder 13. Then, in conjunction with the temperature sensing mechanism 7, the temperature inside the outer cylinder 1 can be monitored, which is convenient for the operator to adjust the temperature later. At the same time, through the structural design of the motor 8, gear 9 and gear disc 10, the rotation of the inner mesh cylinder 13 can be easily realized, which in turn drives the tea leaves inside the inner mesh cylinder 13 to rotate, so as to realize the free fall of the tea leaves during the rotation process, so as to achieve uniform heating of the tea leaves.

[0026] The dehumidification assembly includes an air pump 2, a cooling chamber 3, a thermoelectric cooler 4, and an L-shaped connecting pipe 6.

The outlet is connected to the inner top of the outer cylinder 1 and the top of the other side of the cooling chamber 3 respectively. Through the structural design of this component, high-temperature water vapor can be extracted, and then, in conjunction with the cooling chamber 3 and the semiconductor cooling chip 4, the high-temperature water vapor is liquefied. Then, the gas can be discharged into the interior of the outer cylinder 1 through the L-shaped connecting pipe 6, the aluminum heat conduction pipe 17 and the U-shaped connecting pipe 18, and so on, to achieve the function of removing water vapor. Finally, through the material and installation position design of the aluminum heat conduction pipe 17, the liquefied gas can be heated to facilitate the circulation and discharge of the gas.

[0027] The air-cooling assembly includes a connecting pipe 5, an input pipe 15, an output pipe 14, and an air pump 12. The air pump 12 is installed on the bottom of the outer cylinder 1 away from the toothed disc 10, and the output end of the air pump 12 is connected to the inner bottom of the outer cylinder 1. The connecting pipe 5 is installed on the inner bottom of the cooling chamber 3. One end of the front side of the connecting pipe 5 is provided with an input pipe 15 extending to the outside of the cooling chamber 3, and the other end of the back side of the connecting pipe 5 is provided with an output pipe 14 extending to the outside of the cooling chamber 3. The output pipe 14 is connected to the input end of the air pump 12. Through the structural design of the cooling chamber 3, the semiconductor cooling chip 4, and the connecting pipe 5, the cooling of the outside air can be easily achieved, so as to facilitate the subsequent cooling and color fixing operation of the tea leaves inside the inner mesh cylinder 13.

[0028] On one side of the bottom of the outer cylinder 1 away from the gear disc 10 and on one side of the top of the outer cylinder 1 close to the gear disc 10, mounting plates are provided, and the mounting plates cooperate with the second air pump 12 and the motor 8 to facilitate the fixed installation of the second air pump 12 and the motor 8. On the edges of both sides inside the outer cylinder 1, ball grooves are evenly provided, and inside multiple groups of ball grooves, balls that fit the outside of the inner net cylinder 13 are engaged, which is convenient for improving the stability of the later rotation of the inner net cylinder 13. The connecting pipe 5 is made of a continuous "zigzag" structure and is integrally installed in an arc shape at the inner bottom of the cooling chamber 3, which is convenient for extending the residence time of air inside the connecting pipe 5 and ensuring the later air cooling efficiency. Moreover, through the arc-shaped structural design, it is also convenient for the bottom of the connecting pipe 5 to be fitted and installed with the inner bottom of the cooling chamber 3. At both ends of both sides of the bottom of the outer cylinder 1, support rods are provided, and anti-slip blocks are provided at the bottoms of the four support rods, which is convenient for improving the stability of the placement and support of the outer cylinder 1 and the components above it. At the bottom of one end of the front of the cooling chamber 3 and at the top of one end of the front of the outer cylinder 1, a water outlet and an exhaust port are respectively provided, and sealing covers are covered inside the water outlet and the exhaust port, which is convenient for later extracting the liquid inside the cooling chamber 3 and discharging the high-temperature gas inside the outer cylinder 1 during cooling.

[0029] Working principle: During use, the operator can first open the sleeve 16 and then put the green tea to be killed into the inner net cylinder 13, and then cover the sleeve 16. At this time, the motor 8 can be used to rotate the gear 9. Through the meshing of the gear 9 and the gear disc 10, the rotation of the sleeve 16 and the inner net cylinder 13 inside the outer cylinder 1 can be realized. Through the rotation of the inner net cylinder 13, the mixing operation of the tea leaves inside it can be realized, which is convenient for improving the uniformity of the later heating of the tea leaves. At the same time, through the operation of the spiral heating tube 11, the heating function inside the outer cylinder 1 can be realized, and then through heating, the killing-green operation of the tea leaves inside the inner net cylinder 13 can be realized. At the same time, through the self-structure design of the temperature sensing mechanism 7, the temperature inside the outer cylinder 1 can be monitored, so as to facilitate the operator to control the spiral heating tube 11 according to the actual operation requirements later, so that the tea leaves can be killed at an accurate temperature.

[0030] Simultaneously, the high-temperature water vapor generated during the blanching process inside the outer cylinder 1 is drawn into the cooling chamber 3 by the air pump 2. The cooling chamber 3 is then cooled by the semiconductor cooling chip 4. Upon entering the cooling chamber 3, the high-temperature water vapor liquefies, and the water droplets fall directly to the bottom of the cooling chamber 3 for storage. Excess gas is then discharged through the L-shaped connecting pipe 6 into the aluminum heat pipe 17. The aluminum heat pipe 17 is designed to be installed inside the outer cylinder 1, and its thermal conductivity is well-suited to the aluminum material. Yes, it can heat the excess gas discharged into the aluminum heat-conducting pipe 17 through the L-shaped connecting pipe 6. After the gas is heated, it can be discharged back into the outer cylinder 1 through the U-shaped connecting pipe 18 to realize the gas recycling function. It also facilitates the gas to carry water vapor into the cooling chamber 3. At the same time, the discharge of the heated gas will not cause the water vapor inside the outer cylinder 1 to liquefy, and it can also reduce the wear and tear of the spiral heating pipe 11. It increases the dehumidification function of the machine in the later stage of tea fixing and improves the quality of tea production in the later stage.

[0031] After the tea-making process is completed, the operation of air pump 2 and spiral heating tube 11 is turned off. Then, air pump 2 can draw outside air into the interior of connecting tube 5 through input tube 15. Connecting tube 5 is installed inside cooling chamber 3, which can facilitate the cooling of outside air inside connecting tube 5 in conjunction with semiconductor cooling chip 4. At the same time, the continuous "V" shape design of connecting tube 5 can extend the cooling time of outside air inside cooling chamber 3, ensuring the cooling performance of outside air. The cooled air can be discharged into the interior of output tube 14 through connecting tube 5, and finally discharged into the interior of outer cylinder 1 through the output end of air pump 2 12. Then, the cold air can carry the high temperature gas out through the exhaust port to achieve the cooling operation of tea leaves inside inner mesh cylinder 13. This facilitates the cooling and color fixing of tea leaves after tea-making, increases the versatility of the tea-making machine, and eliminates the need to take out the tea leaves after tea-making and put them into the cooling mechanism for cooling.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
