Microbial fermentation method

Abstract

The invention belongs to the technical field of tea fermentation, and specifically relates to a microbial fermentation method. A pile-turning device used in the method includes a number one shaft; thetwo ends of the number one shaft are rotatably connected to rectangular plates; the bottom ends of the rectangular plates are movably sleeved by rectangular frames; supporting plates are fixed on thebottom ends of the rectangular frames; the bottom end of each supporting plate is rotatably connected to two moving wheels; number one motors are fixed on the top ends of the supporting plates and movably connected to the corresponding moving wheels closest to the number one motors through number one synchronous belts; and push rod motors are fixed on the sidewalls of the rectangular frames. Rapid, uniform and efficient pile turning can be performed on tea piles through the pile-turning device, and the turned tea piles can be spread out so as to make the tea piles at uniform pile heights, sothat the temperature of the tea piles can be kept consistent; the efficiency of the pile turning of the tea piles can be enhanced by using the pile-turning device; and the microorganism in the tea piles can be in suitable growing environment, so that the effects and efficiency of microbial fermentation can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of tea fermentation, in particular to a microbial fermentation method. Background technique [0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics and culture conditions of the strain itself. The application scope of fermentation engineering includes: pharmaceutical industry, food industry, energy industry, chemical industry, agriculture, environmental protection, etc. [0003] Ripe tea, made from Yunnan big-leaf sun-dried green tea as raw material, is called cooked tea after being fermented and fermented. Ripe tea is brownish red in color, pure in taste, and has a unique aroma. Pu'er cooked tea is very popular among the public because of its mild nature and good health care...

AI Technical Summary

Problems solved by technology

[0004] When fermenting cooked tea with microorganisms, it needs to be piled and fermented. During pile fermentation, the pile of tea needs to be turned over. In the south where the temperature is high, the number of piles turned is more when making cooked tea, which increases the labor intensity of the workers. , and the hand-turned tea piles are not uniform enough, so that the temperature of the tea piles varies unevenly, thereby affecting the fermentation of the tea piles. Accordingly, the present invention proposes a microbial fermentation method
