Green tea fixation equipment

Abstract

The invention discloses green tea fixation equipment. The green tea fixation equipment comprises a machine frame and a transmission belt which is arranged in the axial direction of a cylinder body, wherein the cylinder body which is horizontally arranged and a friction roller for driving the cylinder body to rotate are rotatably connected to the machine frame; the cylinder body comprises an innerlayer in the shape of a sieving cylinder and an outer layer; the outer layer and the inner layer are arranged at intervals; an RO membrane is arranged on the outer wall of the inner layer; one end ofthe cylinder body is opened, and a sealing cover is arranged at the opened end of the cylinder body; an air delivery pipe is rotatably connected to the other end of the cylinder body; a plurality of stirring units and a plurality of air outlets are arranged / formed on / in the air delivery pipe in the axial direction; each stirring unit comprises a plurality of stirring rods which are uniformly distributed on the air delivery pipe in the circumferential direction and an end surface gear fixed on the inner wall of the inner layer; one ends of the stirring rods are rotatably connected with the airdelivery pipe, and each driven gear which is meshed with the corresponding end surface gear is fixed to the other end of the corresponding stirring rod. The invention aims to provide the green tea fixation equipment being good in fixation effect on tea leaves.

Description

technical field [0001] The invention belongs to the field of tea processing, and in particular relates to green tea degreening equipment. Background technique [0002] Green tea is a kind of non-fermented tea, which is made through processes such as greening, rolling, and drying. Its quality features are "three greens" (green appearance, green soup color, and green leaf bottom), high aroma, fresh taste, and more Natural substances in fresh leaves are retained, such as tea polyphenols, amino acids, chlorophyll, vitamins, etc. The basic processing technology of green tea is: spreading → finishing → kneading → drying. [0003] Among them, fixing is an important process, and the effect of fixing directly affects the quality of tea. 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 sof...

AI Technical Summary

Problems solved by technology

[0005] However, the tea greening machine in the prior art is simple in structure, the heat utilization efficiency is not high, the heat loss is serious, and the processing efficiency is low, which leads to a bad effect on the greening of the tea leaves and affects the quality of the tea leaves.

It will also cause the tea leaves to easily remain in the drum, making it difficult to take out and inconvenient to use
