[0002] Black tea is fully fermented tea, and the fermentation process is a key step in black tea production. The following is the basic process of black tea fermentation:

[0003] Picking: Select suitable tea buds and leaves, usually fresh tea leaves.

[0004] Withering: Spreading out the picked tea leaves to allow them to lose water naturally, usually in a cool and ventilated place, to soften the tea leaves and facilitate subsequent rolling.

[0005] Rolling: Roll the withered tea leaves to destroy the cell structure of the tea leaves, release the tea juice and promote fermentation.

[0006] Fermentation: The rolled tea leaves are placed under suitable temperature and humidity for fermentation. The fermentation time and environmental conditions will affect the aroma and taste of the tea. The degree of fermentation of black tea is usually between 80% and 100%.

[0007] Drying: After fermentation is complete, the water content of the tea leaves is removed by drying to stop the fermentation process and preserve the flavor and quality of the tea.

[0008] Screening and Packaging: Finally, the dried tea leaves are screened to remove impurities and then packaged in preparation for sale.

[0009] The temperature and humidity of black tea are controlled by heating to reduce the temperature and humidity to achieve the adjustment of temperature and humidity during the adjustment. However, during the adjustment, the increase and decrease of temperature and humidity will take time for the temperature and humidity in the fermentation device to reach the target temperature. Therefore, the adjustment process will cause the local temperature inside to change, thereby affecting the fermentation of the tea leaves. Therefore, the present application designs a black tea constant temperature fermentation device that provides a constant temperature and humidity airflow into the fermentation device to solve this technical defect of the prior art.

[0043] A temperature and humidity display screen 9 is fixedly mounted on the outside of the air storage box 3 , and the temperature and humidity display screen 9 is electrically connected to a temperature and humidity sensor 1 located in the air storage box 3 , and an automatic switch valve 8 is connected to the outside of the exhaust head 7 .

[0044] The temperature and humidity sensor senses the temperature of the air inside the air storage box 3.

[0045] The exhaust member,

[0046] It includes an exhaust pipe 10 connected between the air storage box 3 and the fermentation box 1, and the outside of the exhaust pipe 10 is connected to an automatic switch valve 2 11.

[0047] See also Figures 3 to 4 In this embodiment, the fermentation box 1 is provided with an exhaust component for quickly discharging the air flow inside the fermentation box 1 to allow constant temperature and humidity air flow to enter.

[0048] It should be noted that the exhaust assembly includes a driving component and an exhaust control component;

[0049] Drive parts,

[0050] It includes a connecting pipe 12 connected to the outside of the fermentation box 1, the other end of the connecting pipe 12 is connected to a mounting cylinder 13, a motor 14 is installed in the mounting cylinder 13, and a fan blade 15 is fixed to the output shaft of the motor 14 by fastening screws.

[0051] The exhaust control component,

[0052] It includes an exhaust control air pipe 16 connected to the other side of the mounting tube 13, an elastic telescopic rod 17 is installed inside the exhaust control air pipe 16, and the elastic telescopic rod 17 is composed of a spring and two ends of the telescopic rod that are fixed to each other. The other end of the elastic telescopic rod 17 is fixed with a switch sealing piece 18 that fits tightly with the inner wall of the exhaust control air pipe 16. The diameter of the switch sealing piece 18 is equal to the inner diameter of the exhaust control air pipe 16. When the elastic telescopic rod 17 is in an extended state, the switch sealing piece 18 is separated from the exhaust control air pipe 16.

[0053] A second temperature and humidity display screen 19 is fixedly mounted on the surface of the fermentation chassis 1 , and a second temperature and humidity sensor 2 located inside the fermentation chassis 1 is electrically connected to the second temperature and humidity display screen 19 . An operation display panel 20 is fixedly mounted on the surface of the fermentation chassis 1 .

[0054] The temperature and humidity sensor 2 is used to sense the temperature and humidity inside the fermentation box 1.

[0055] The working principle of the above embodiment is:

[0056] When the temperature and humidity in the fermentation chassis 1 need to be changed, the temperature of the room is set on the small mobile air conditioner 2, and the small mobile air conditioner 2 is turned on, so that the airflow of the set temperature enters the connecting socket 4, and the connecting socket 4, the sealing cover 6, the air intake hose 5 and the air storage box 3 are connected to each other, so that the airflow enters the air storage box 3. At this time, the automatic switch valve 1 8 is opened and the automatic switch valve 2 11 is closed. While the gas is discharged through the exhaust head 7, the temperature and humidity are viewed in real time through the temperature and humidity display screen 1 9. After the temperature and humidity of the airflow stored in the air storage box 3 are equal to the set temperature, the set automatic switch valve 1 8 is closed and the set automatic switch valve 2 11 is opened, so that the airflow enters the fermentation chassis 1 through the exhaust pipe 10;

[0057] Moreover, when the airflow enters the fermentation box 1, the motor 14 is started synchronously to drive the fan blades 15 to rotate and blow out the airflow, and at the same time, the original internal air in the fermentation box 1 is extracted through the connected connecting pipe 12. At the same time, under the action of air pressure, the switch sealing piece 18 is pushed to separate from the exhaust control pipe 16, and the elastic telescopic rod 17 is synchronously extended, so that the original internal air in the fermentation box 1 is discharged from the exhaust control pipe 16;

[0058] Thus, the airflow of set temperature and humidity enters the fermentation box 1 from the exhaust duct 10, and combined with the rapid discharge of the original internal air in the fermentation box 1, the constant temperature and humidity airflow can be quickly filled into the fermentation box 1 until the temperature and humidity values ​​on the temperature and humidity display screen 2 19 reach the set values. After reaching the set values, the automatic switch valve 2 11 is closed, and the small mobile air conditioner 2 and the motor 14 stop working. When the air pressure is stable, the elastic telescopic rod 17 elastically contracts and resets, driving the sealing piece 18 to move and seal the exhaust control pipe 16, so that the temperature and humidity in the fermentation box 1 quickly reach the set temperature, avoiding the traditional direct change of temperature and humidity causing changes in the temperature and humidity of the airflow, affecting the fermentation and taste of the tea.

[0059] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
