Tea leaf enzyme deactivation device

Abstract

The invention belongs to the field of tea processing, and particularly discloses a tea leaf enzyme deactivation device. The device comprises a frame; an enzyme deactivation barrel is fixed on the frame; first air bags and second air bags are staggered on the inner wall of the enzyme deactivation barrel; the upper part of each first air bag is provided with a first projection; a first spring is fixedly arranged between the two inner side walls at each first projection and in each first air bag; each first projection is provided with a first magnetic block; the inner wall of the upper end of each first air bag is provided with a first air inlet hole; the outer wall of the upper end of each first air bag is provided with a first air outlet hole; the outer wall of the lower end of each secondair bag is provided with a second air inlet hole; the outer wall of the lower end of each second air bag is provided with a second air outlet hole; a stirring shaft is rotatably connected onto the frame; the stirring shaft is provided with some supporting rods which are close to the first projections and the second projections and are uniformly distributed in circumferential direction; and one ends, far from the stirring shaft, of the supporting rods are fixedly connected to an electromagnet for repelling first magnetic blocks and second magnetic blocks. The adopted scheme of the invention solves the problem that the tea leaves are easy to heap up during the enzyme deactivation process.

Description

technical field [0001] The invention belongs to the field of tea processing, and in particular relates to a tea greening device. Background technique [0002] The processing of tea is composed of multiple processing procedures. Green tea goes through processes such as greening, rolling, and drying; black tea goes through processes such as withering, rolling, fermentation, and drying. The same is true for other teas, which go through a series of technological processes from fresh leaves to finished tea. [0003] Among them, fixing refers to destroying and passivating the oxidase activity in fresh tea leaves by high temperature, inhibiting the enzymatic oxidation of tea polyphenols in fresh leaves, evaporating part of the water in fresh leaves, making the tea leaves soft and easy to knead and shape. Existing tea degreening usually adopts a roller degreening machine, the tea leaves are placed in the drum, the side wall of the drum is heated, and the drum is rotated at the sam...
