Description

Technical Field

[0001] The invention relates to the technical field of tea fermentation, and in particular to a novel fermentation vehicle for homogeneous tea fermentation. Background Art

[0002] Dark tea is a fermented tea mediated by microorganisms. During the fermentation process, the enzymes produced by microorganisms catalyze a series of biochemical reactions in the tea contents, including redox reactions, hydrolysis reactions, and condensation reactions, and finally obtain fermented products that are completely different from the raw tea in color, flavor, and efficacy. Several important factors affecting dark tea fermentation are temperature, water content, oxygen, and fermentation time. The appropriate temperature is conducive to the activity of microbial enzymes, and the generally suitable temperature is 30∽40℃; the second is the water content of tea leaves, and the water content suitable for microbial growth should be above 20%; the fermentation speed is closely related to the oxygen supply, so it is very important to maintain good air exchange; and the fermentation time is related to the fermentation speed. If there is sufficient oxygen and the fermentation speed is fast, the fermentation time can be shortened, otherwise it will be extended. Like any biological fermentation project, the fermentation conditions have a great influence on the flavor of the fermented product, and the fermentation conditions are limited by the fermentation equipment. Therefore, the design of the fermentation equipment plays a vital role.

[0003] In the previously reported homogeneous fermentation technology, tea leaves are placed in a hollow basket and then placed on an open rack for fermentation. In actual use, it was found that due to the built-in circulating air in the fermentation room, the surface moisture of some tea leaves would be lost too quickly. It is also because of the large difference in moisture content between the surface and the interior of the tea pile that the fermentation flavor consistency is poor.

[0004] Therefore, it is necessary to improve the existing fermentation equipment to effectively avoid the problem of excessive evaporation of local tea moisture caused by built-in circulating air. Summary of the invention

[0005] The purpose of the present invention is to provide a novel fermentation vehicle for homogeneous tea fermentation to solve the problems raised by the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0007] An embodiment of the present invention provides a novel fermentation vehicle for homogeneous tea fermentation, comprising:

[0008] Fixed frame;

[0009] The universal wheel is fixedly installed at the bottom of the fixing frame and is used for supporting the fixing frame.

[0010] Through the above technical solution, the universal wheels facilitate the movement of the fixing frame.

[0011] Furthermore, stainless steel plates are fixedly mounted on the back, both sides and top of the fixing frame.

[0012] Through the above technical solution, the stainless steel plate prevents the moisture on the surface of the tea leaves from being lost quickly.

[0013] Furthermore, ventilation holes are provided on the surface of the stainless steel plate.

[0014] Through the above technical solution, the air holes facilitate the fermentation of tea leaves and the entry of oxygen.

[0015] Furthermore, a switch door is movably connected to the front side of the fixing frame via an axle pin, and a ventilation hole is also provided on the surface of the switch door.

[0016] Through the above technical solution, opening and closing the door makes it easy to take out the tea leaves, thereby improving the efficiency of tea leaf fermentation.

[0017] Furthermore, both sides of the inner wall of the fixing frame are fixedly connected with drawer grooves, and the inner side of the drawer groove is provided with a drawer-type basket, and the drawer-type basket includes a frame and a wire mesh.

[0018] Through the above technical solution, the drawer slot is convenient for placing and taking out tea leaves, which improves the efficiency of tea leaf fermentation and is convenient for users.

[0019] Furthermore, the vent holes have a diameter of 1 to 2 cm and are spaced 10 to 20 cm apart.

[0020] Through the above technical solution, the air holes are conducive to the contact between tea leaves and oxygen, thereby increasing the fermentation speed.

[0021] Furthermore, a gap of 2 to 5 cm should be left between the drawer-type basket and the surrounding steel plates for air circulation. The depth of the drawer-type basket is set at 10 to 30 cm. The optimal thickness of tea leaves stacked is 15 to 20 cm. A gap of 5 to 10 cm should be left between the drawer-type baskets.

[0022] Through the above technical solution, a gap is left between the drawer-type basket and the square plate, which facilitates the circulation of air.

[0023] The above solution of the present invention includes at least the following beneficial effects:

[0024] 1. The present invention can eliminate the problem of uneven fermentation caused by rapid evaporation of water caused by circulating air to the greatest extent through the use of a fermentation vehicle, and the ventilation holes on the panel can ensure sufficient entry of oxygen, which helps to increase the fermentation speed and replace the existing fermentation method through the rack, thereby achieving the effect of efficient fermentation.

[0025] 2. The fermentation vehicle of the present invention is easy to move, which can help reduce the labor required for turning the pile and adding water. At the same time, the fermentation vehicle can greatly improve the efficiency of space utilization, simplify the management of the fermentation process, and facilitate cleaning work.
