Tea leaf pile fermentation device and method based on automatic splicing movable material bearing table

Abstract

The invention discloses a tea leaf pile fermentation device and method based on an automatic splicing movable material bearing table. Automatic pile fermentation of tea leaf materials is realized through cooperative work of a material spreading system, a pile fermentation system and discharging conveying equipment. The pile fermentation process is completed in a pile fermentation bin, and the bottom of the bin is an automatic splicing movable material bearing table which is formed by combining a plurality of material bearing table units. Each material bearing table unit is made of concrete blocks, earthenware, battens or bamboo boards with certain thickness, the internal structure is relatively loose, a survival space can be provided for beneficial bacteria needed by pile fermentation, and the functions of heat preservation, humidity control, moisture absorption and the like are achieved. The tea leaves are subjected to pile fermentation on the material bearing table, the advantages of a traditional pile fermentation method can be played, and a feasible solution is provided for achieving automation of the pile fermentation process. By adopting the pile fermentation method, the tea materials do not fall to the ground, and the product is clean and sanitary and has good purity; the pile fermentation process is fully automatic, and the labor intensity is greatly reduced; and the key links are digitally controlled, so that the product quality is better guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tea production and processing, and relates to a tea stacking and stacking processing method, in particular to an automatic stacking device and method that can take advantage of the traditional stacking technology. Background technique [0002] In the academic classification of tea products, cooked tea is classified as dark tea. Ripe tea is made from large-leaf sun-dried green tea as raw material, and processed through fermentation and other processes. Wodui is the fermentation process in the process of making Pu-erh cooked tea, and it is also a key process that determines the quality of cooked tea. The traditional operation process of the Wodui process is as follows: First, the sun-dried green tea is piled up to a certain height to form a tea pile; then the surface of the tea pile is covered with a covering such as hemp flakes to keep the tea pile warm and moisturized, so that the tea leaves are fermente...

AI Technical Summary

Problems solved by technology

[0006] 1. The stacking process is carried out on the ground, and the hygienic conditions are poor. Sand, small concrete blocks, rope heads, label strips, cigarette butts, fruit shells, chicken feathers, hair and other common debris on the ground are easily mixed into the tea materials, resulting in subsequent refined processing It is difficult to guarantee the purity of tea materials due to the large workload of picking out sundries

[0007] 2. Key parameters such as tidal volume and pile temperature are all controlled by manual experience, the product quality fluctuates greatly between batches, and the degree of homogenization is not high

[0008] 3. The work of mixing tea with tide water, stacking, covering, and turning is all done manually, which requires a lot of labor and high labor intensity; and people are in frequent contact with tea materials, and hair, sweat, and shoe sole adhesions are easy to fall off into the tea material

[0010] Some tea companies and scientific research institutions have tried the closed-tank stacking technology. Although this method solves the problem of hygiene, it completely abandons the advantages of the traditional stacking method. The product quality is not ideal, and sometimes the tea tastes weak. , sourness and other adverse consequences

So far, this kind of pile method has not been popularized and applied
