Off-ground pile fermentation technology for fermented tea

Abstract

The invention discloses an off-ground pile fermentation technology for fermented tea. The off-ground pile fermentation technology for the fermented tea comprises the following specific steps of: making a ground early-stage preparation, carrying out processing that a 30*30 cm vent hole is reserved on the bottom in every 10 meters in a workshop place for preparing the fermented tea, evenly arrangingcement piles on the ground of the place, and placing a wood plate on the top parts of the cement piles; and after 20% of moisture is sprinkled into sunning raw tea, carrying out pile fermentation onthe wood plate, overturning for one time in every three days, continuously overturning for three times, and adding 20% of moisture in sequence according to a situation while overturning is carried outto enable a water content of a pile is 40%. The invention aims to provide a reasonable off-ground pile fermentation technology capable of avoiding insufficient situations, including insanitation, water accumulation, no circulation of bottom layer air, breeding of putrefying bacteria including aspergillus glaucus and the like and also capable of avoiding an insufficient situation that big-pile fermentation can not be carried out by a small box, and moisture flowing caused by excessive pile tide water on the wood plate for the first time can be avoided. According to the fermentation technology,the problems of uneven moisture, uneven dampness and heat and excessive aspergillus niger can be avoided.

Description

technical field [0001] The invention relates to the technical field of tea making, in particular to a process for fermenting and fermenting cooked tea from the ground. Background technique [0002] People use heaping (stacking) to ferment cooked tea on the concrete floor, which will lead to poor sanitation, stagnant water, poor air circulation at the bottom of the heap, and the growth of spoilage bacteria (Aspergillus chlorophyll). Small-frame fermentation cannot achieve large-heap fermentation, and has to be split into 1-2 tons of small-heap fermentation, resulting in problems such as increased costs and unsatisfactory results. Both the traditional composting fermentation and the existing off-the-ground fermentation process are based on the traditional composting fermentation: After the tide is 30%-40%, it takes 7-8 days as a cycle to turn the compost and dissolve 4-5 times before opening Ditch stacking for 7-10 days, and natural drying for 5-8 days. For the first time, t...

Problems solved by technology

It will also increase the total ash content, water-soluble ash content and water-insoluble ash content of the raw materials, which will affect the brightness of the soup color.

Direct ditching and stacking in the later stage will accelerate the mildew-promoting effect and accelerate the oxidation and reduction of polyphenols such as catechins, which will affect the unsatisfactory aroma of the pile. Odor reverses and rises, causing heap and miscellaneous odors

Drying too quickly leads to dry mouth when drinking new tea
