Temperature and humidity automatic control fermentation device in tea production process

Abstract

The invention discloses a temperature and humidity automatic control fermentation device in tea production process. The device comprises a steam oven (1), a heating furnace (2) and a fermentation chamber (7), wherein the steam oven (1) produces steam which is conveyed to the fermentation chamber (7) through a porous steam pipe; high temperature air is produced by the heating furnace (2) and is conveyed to the fermentation chamber (7) through a porous heating pipe (6); a detection module (8) is arranged in the fermentation chamber (7) and is used for detecting temperature and humidity in the fermentation chamber; the temperature and humidity are displayed on instruments (3); and switch modules (5) control the opening and closing of the porous steam pipe (4) and the porous heating pipe (6) according to the temperature and humidity. The temperature and humidity automatic control fermentation device not only is suitable for black tea production, but also can meet requirements of fermentation production process for fermentation teas, such as yellow tea, dark green tea and pu'er tea; and production practice test for a plurality of teas proves that the production process is stable, and product quality is quite high.

Description

technical field [0001] The invention is a temperature and humidity automatic control fermentation device in tea production designed to solve the need of key factors temperature and humidity in the production and fermentation process of black tea, which is affected by the change of season and environment and the fermentation quality. Background technique [0002] The initial production process of Gongfu black tea is divided into four processes: "fresh leaves withering, rolling, fermentation, and drying". The satisfaction of the conditions of the fermentation process is the key to the quality of Gongfu black tea. The purpose of fermentation is to enhance the activity of enzymes, promote the oxidation of polyphenols, form the unique color and taste of black tea; emit green gas, and form a strong aroma. The primary conditions that affect the fermentation of black tea are temperature and humidity. However, in the production process of Gongfu black tea, due to the influence of p...

AI Technical Summary

Problems solved by technology

However, in the production process of Gongfu black tea, due to the influence of production season, fermentation environment (temperature, humidity), tea tree variety, quality of withered leaves and degree of rolling, the fermented leaves are affected by the degree of fermentation under different temperature and humidity environments, which in turn affects The quality of black tea quality

At present, although some simple fermentation methods for maintaining temperature and humidity can be used in production, it can only be based on experience, and it is impossible to maintain quantitative and controllable temperature and humidity adjustment methods to ensure that the temperature and humidity in the fermentation process of Gongfu black tea are different. phase adjustment
