Description

Technical Field

[0001] This invention relates to the field of white tea fermentation technology, specifically to an apparatus and method for white tea fermentation. Background Technology

[0002] White tea is a lightly fermented tea. Its fermentation process mainly refers to the enzymatic reaction that occurs when the tea leaves are withered and dried under the action of oxygen molecules in the air. The fresh white tea leaves are spread out in a certain thickness and allowed to evaporate moisture and transform their contents under suitable temperature and humidity.

[0003] For example, patent CN222090696U discloses a device for white tea fermentation, including a movable frame, a uniform air distribution component, and a placement component. The movable frame is equipped with a heating component, and the output end of a heat-insulating pipe is connected to multiple fermentation mechanisms. Each fermentation mechanism includes a uniform air distribution component and a placement component. The uniform air distribution component is installed on the inner wall of the movable frame. The placement component is detachably installed on the uniform air distribution component and is used to place the white tea. This invention, through the arrangement of a blower, heating component, heat-insulating pipe, and multiple fermentation mechanisms, facilitates rapid and uniform withering of white tea, improving fermentation quality and efficiency, and ultimately enhancing the quality of the white tea.

[0004] In existing technologies, when white tea is piled on a fermentation net, there is a problem of limited ventilation in the inner layer. This causes the outer layers of tea leaves to ferment and wither at a significantly faster rate than the inner layers due to direct contact with oxygen. This results in a stratification phenomenon where the surface layer is over-oxidized and the inner layer is under-fermented. Ultimately, this leads to significant differences in the degree of withering within the same fermentation net, severely affecting the uniformity of the finished product's quality. Furthermore, there is the problem of the blower directly drawing in unfiltered air for ventilation, causing dust particles in the air to be directly deposited on the surface of the white tea leaves, forming a dust layer. This ultimately causes blockage of the tea leaves' pores and hinders enzymatic reactions during withering, leading to decreased withering efficiency and quality defects such as cloudy aroma and dark color in the finished tea. Therefore, we propose a device and method for white tea fermentation. Summary of the Invention

[0045] A method for fermenting white tea, applicable to the aforementioned apparatus for fermenting white tea, includes the following steps:

[0046] S1. Open the sealed door assembly 3. Align each white tea placement box 4105 with the main slot 4102 using each pull handle 4108. Align each insert 4106 with the secondary slot 4103. Then insert the white tea placement box 4105 into the main slot 4102. At this time, the white tea placement box 4105 will cause the insert 4106 to slide on the inner wall of the secondary slot 4103. Once the inner end of each magnetic strip 4107 is in contact with the outer wall of the rotating placement box 4101, close the sealed door assembly 3.

[0047] S2, the stepper motor 45 is powered and controlled by the external power supply and external controller. The stepper motor 45 drives the rotating shaft 46 and two small gears 47 to rotate. The small gears 47 drive the external gear ring 48 and the rotating cone frame 43 to rotate slowly in the opposite direction. The rotating cone frame 43 drives multiple first follower rotating columns 44 to rotate on the inner wall of the annular groove 42. The rotating cone frame 43 drives the white tea follower shaking component 49 and the white tea placing component 410 to rotate.

[0048] S3, the fan 419 and heating wire 417 are powered and controlled by the external power supply and external controller. The fan 419 draws in the outside air and the heating wire 417 heats the filtered air. The heated air dries the white tea through the main air inlet pipe 415, the secondary air inlet pipe 413 and the rotary joint pipe 414. The air that has passed through the white tea is finally discharged to the outside environment through the secondary air outlet pipe 412 and the main air outlet pipe 421.

[0049] Working principle: First, open the locking handle 33 and pull it outward. The locking handle 33 directly rotates the sealed door body 31 and the observation window 32. Next, align each white tea box 4105 with the main slot 4102 using each pull handle 4108, and align each insert 4106 with the secondary slot 4103. Then, insert the white tea box 4105 into the main slot 4102. The white tea box 4105 then moves the insert 4106 along the inner wall of the secondary slot 4103. When each magnetic strip 4106... After the inner ends of 107 are in contact with the outer wall of the rotating placement box 4101, the sealing box door body 31 is pushed inward and rotated using the locking handle 33, and then the locking handle 33 is locked. Then, the stepper motor 45 is powered and controlled by the external power supply and external controller. The stepper motor 45 drives the rotating shaft 46 and two small gears 47 to rotate. The small gears 47 drive the outer gear ring 48 and the rotating cone frame 43 to rotate slowly in the opposite direction. The rotating cone frame 43 drives multiple first follower rotating columns 44 to rotate on the inner wall of the annular groove 42. The rotating cone frame 43 drives the white tea following and shaking component 49 and the white tea placing component 410 to rotate. During this process, the rotation of the rotating frame 491 directly drives multiple springs 494, sliding frame 495, sliding bar 496 and the second following rotating column 497 to rotate. The second following rotating column 497 moves in the wave groove track 498, driving the sliding bar 496 to move up and down reciprocally. The sliding bar 496 moves up and down reciprocally in the secondary sliding groove 493. At this time, the sliding bar 496 directly drives the sliding frame 495 in the main sliding groove 492. The sliding frame 495 directly drives the white tea placement component 410 to move by reciprocating up and down. During the entire rotation process, the fan 419 and heating wire 417 can be powered and controlled by an external power supply and an external controller. The fan 419 draws in outside air, and the heating wire 417 heats the filtered air. The heated air dries the white tea by passing through the main air inlet pipe 415, the secondary air inlet pipe 413, and the rotary joint pipe 414. The air that has passed through the white tea is finally discharged to the outside environment through the secondary air outlet pipe 412 and the main air outlet pipe 421.
