Tea fermentation equipment with temperature control and ventilation functions

Abstract

The invention relates to tea fermentation equipment with temperature control and ventilation functions. The tea fermentation equipment comprises a main body and four support blocks. A PLC (programmable logic controller), a fermentation chamber, a fixing mechanism, a temperature control mechanism and a ventilation mechanism are arranged in the main body; the temperature control mechanism comprisesa heat conducting tube, an air exhauster, a heat radiating unit and a heat absorption unit; the heat radiating unit comprises a heat radiating tube and a heat radiating box; the heat absorption unit comprises a heat absorption tube, a heating tube and a heating box; and the ventilation mechanism comprises a drive unit, a piston, a compression tube, a first valve and an exhaust tube. The tea fermentation equipment with the temperature control and ventilation functions can regulate the tea fermentation temperature according to tea fermentation time by the aid of the temperature control mechanism, so that the temperature at each stage during tea fermentation is the most suitable temperature for tea fermentation, and the tea quality can be improved. Moreover, the tea fermentation equipment canregulate the ventilation volume according to the tea fermentation time by means of the ventilation mechanism, thus, the tea fermentation degree is convenient to control, and the tea quality can be improved.

Description

technical field [0001] The invention relates to the field of tea processing equipment, in particular to a tea fermentation equipment with temperature control and ventilation functions. Background technique [0002] Tea fermentation is a very important step in tea processing technology, and it is the key to determine the quality of tea color, aroma and taste. After finishing, the tea cells are damaged and broken, the enzymatic oxidation pathway of polyphenols is blocked, the polymerization is accelerated, and fermentation begins. [0003] However, the tea fermentation temperature is 32°C to 40°C in the early stage and 15°C to 18°C ​​in the later stage, and the existing tea fermentation equipment cannot adjust the temperature of the tea fermentation according to the length of tea fermentation, resulting in the quality of the tea produced by the existing tea fermentation equipment. Not only that, the oxidation rate of tea leaves is high at the initial stage of fermentation, an...

Problems solved by technology

[0003] However, the tea fermentation temperature is 32°C to 40°C in the early stage and 15°C to 18°C ​​in the later stage, and the existing tea fermentation equipment cannot adjust the temperature of the tea fermentation according to the length of tea fermentation, resulting in the quality of the tea produced by the existing tea fermentation equipment. Not only that, the oxidation rate of tea leaves is high at the initial stage of fermentation, and oxygen supply must be sufficient, but the existing tea fermentation equipment cannot adjust the ventilation according to the length of tea fermentation, which makes it difficult to control the degree of tea fermentation, resulting in the production of existing tea fermentation equipment. The taste of the tea leaves becomes worse
