Tea fermentation device capable of controlling temperature and humidity by utilizing water mist flowing

Abstract

The invention relates to a tea fermentation device capable of controlling temperature and humidity by utilizing water mist flowing, and belongs to the technical field of tea fermentation. The tea fermentation device comprises a bracket, a water mist discharge pipe, a heating water tank, a gas-water separation device, a fermentation tank, a water mist absorption pipe, a water mist suction nozzle, aventilation frame, a gas heater, an atomizing nozzle, a water mist fan, a water pump and a water heater. Tea leaves needing to be fermented are contained in the ventilation frame, water mist with a certain temperature is sprayed into a fermentation bin through the water mist fan, the tea leaves are kept in an environment with a certain temperature and humidity through flowing of the water mist with the certain temperature to be fermented, and therefore tea leaves with the ideal quality are obtained through fermentation.

Description

technical field [0001] The invention belongs to the technical field of tea fermentation, and in particular relates to a tea fermentation device using water mist flow to control temperature and humidity. Background technique [0002] When tealeaves are fermented, the existing fermentation method mainly adopts " pile " fermentation. Put a certain amount of tea leaves in the house, and spray water on the tea piles (commonly known as tide water). During the fermentation process of tea leaves with a certain amount of water, the heat generated by the decomposition of some organic substances in the piles will accumulate, increasing the temperature inside the piles of fermented tea leaves. When the temperature increases to about 50°C, a large number of beneficial bacteria (or artificially added bacteria) carried by the tea itself when it grows in nature will multiply and grow, which will promote the fermentation of tea. If the temperature is too low, such as only 40°C, some harmful...

AI Technical Summary

Problems solved by technology

These measures have properly improved the quality of "Wodui" fermented tea, but they have not fundamentally solved the problem. They are also affected by local temperature and natural air humidity, and manual turning is extremely unhygienic. Turning is not timely or the humidity in some areas is too high. , easy to form hardening (commonly known as old tea head)

In addition, when the mass of the "wo pile" is less than 7 tons, due to the natural heat dissipation of the fermentation pile, the temperature in the middle area of ​​the fermentation pile cannot rise, and effective fermentation cannot be carried out.

Since the fermentation heap required for the test test cannot be less than 7 tons of tea, the cost of tea for one test is extremely high (use 30 yuan / kg of tea, and a test will consume 210,000 yuan of tea), which leads to the need for tea fermentation (solid-state fermentation) research is very difficult
