Full-automatic Liupao-tea-leaf fermenting jar and fermenting technology thereof

Abstract

The invention discloses a full-automatic Liupao-tea-leaf fermenting jar and a fermenting technology thereof.The full-automatic Liupao-tea-leaf fermenting jar comprises a jar body, a driving device and a control device.A plurality of feeding openings and a transparent window are formed in the lateral side of the jar body, steam pipes are axially arranged on the inner side of the jar body and provided with high-pressure steam spraying nozzles, a discharging opening with a sealing cover is formed in one end of the jar body, and a plurality of ventilation holes are formed in the sealing cover of the discharging opening.The control device comprises a temperature-humidity monitor, a control center and an electric control valve.The fermenting technology of the fermenting jar includes the steps that the temperature and the humidity in the jar body are monitored, rotation of the jar body is automatically controlled, water or steam is sprayed into the jar body through the electric control valve, and pile fermentation and pile overturning are repeated till raw tea is completely fermented.The full-automatic Liupao-tea-leaf fermenting jar and the fermenting technology are reasonable in design, convenient to operate and high in automation degree, and water adding, ventilation, pile overturning and the like of the fermenting jar can be effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of tea processing equipment, and in particular relates to a Liubao tea automatic fermentation tank and a fermentation process thereof. Background technique [0002] Liubao tea is a kind of tea, which belongs to the dark tea category. It is a famous Chinese tea with a history of more than 1,500 years. It was named after it was originally produced in Liubao Township, Cangwu County, Wuzhou City. During the years, it was listed as one of China's top ten famous teas with its unique betel nut fragrance and became a tribute. Famous contemporary Chinese cultural scholars made a cultural orientation for Liubao tea, pointing out that Wuzhou Liubao tea and Yunnan Puer tea are both famous Chinese teas with thousands of years. The older the better, it belongs to the dark tea category. Liubao tea is obtained through fermenting, autoclaving, and aging. Fermentation is the most important production process in the producti...

AI Technical Summary

Problems solved by technology

The traditional method of fermenting Liubao tea is artificial fermentation, and its defects are: ① The fermentation is not uniform, and the fermentation temperature is difficult to control, especially in the middle of the night when no one is guarding. If the fermentation temperature is too high, the tea will be seriously agglomerated, which directly affects the tea quality, causing large economic losses to the production enterprises

②The tea fermentation process needs to be turned on a regular basis. Most of them use manual turning, which is labor-intensive, and the dust in the turning process is relatively large, which seriously pollutes the environment and sanitation, especially causing great damage to the human respiratory system.

At present, some manufacturers have used a fermenter that does not need artificial spraying for adding water and humidification, and does not need manual turning for tea leaves. Unstable, when the pressure in the tank reaches a certain level, equipment failure is prone to occur, and there is also a certain danger to the operator. In addition, the layout of water addition and humidification facilities is unreasonable, and the control of water addition and temperature requires manual and human control. , the temperature and humidity of fermentation are not quantified and digitally controlled, the quality of the product is difficult to be standardized, and continuous and automated production cannot be realized
