Tea leaf twisting and drying device

Abstract

The invention discloses a tea leaf twisting and drying device. The tea leaf twisting and drying device comprises a twisting tank, a twisting disk, a feeding opening, protruding ridges, a baffle plate,a first air cylinder, a filtering mechanism, a first motor, rotating shafts, connecting rods, supporting arms, a sleeving frame, a twisting cylinder, a press cover, a screw rod, a sliding block, a horizontal rod, a second air cylinder, a first air heater, an air pipe, an exhaust fan, a drying box, a connecting shaft, a roller, a feeding hole, a discharging hole, a first belt wheel, a second motor, a second belt wheel, a belt, a feeding box, a charging hole, a drying pipe, a second air heater, an air inlet pipeline, an air outlet pipeline and a drawer, wherein the twisting disk is arranged atthe middle part of the upper end of the twisting tank; and the feeding opening is formed in the middle part of the upper end of the twisting disk. According to the tea leaf twisting and drying devicedisclosed by the invention, the first air heater is arranged, so that thermal wind can be transported to the twisting cylinder through the air pipe for heating tea leaves, and the function of thermaltwisting is realized; and the exhaust fan is arranged, so that air in the twisting cylinder can be drawn out, the temperature is reduced, and the function of cold twisting is realized.

Description

technical field [0001] The invention relates to tea production and processing technology, in particular to a tea rolling and drying device. Background technique [0002] Tea rolling is a very important process in the tea production process. After the tea leaves are withered and greened, the purpose of rolling is to damage the cell walls of the leaves, so that the excess water in the tea leaves can be easily volatilized, so that the tea juice can be attached to the leaves of the tea leaves for easy brewing. The tea leaves can better integrate the tea juice and tea dove into the tea water, which can be divided into hot kneading and cold kneading; the purpose of drying is to use high temperature to destroy enzymes and prevent enzymatic oxidation; Maocha is fully dried to prevent non-enzymatic oxidation, which is beneficial to maintain quality; the third is to emit green odor to further enhance and develop the aroma. [0003] Existing tea rolling devices generally only have the...

AI Technical Summary

Problems solved by technology

[0003] Existing tea rolling devices generally only have the function of hot rolling or cold rolling, and cannot have both at the same time. In addition, during the rolling process, tea leaves are rolled to produce debris, which cannot be filtered out, which greatly increases the labor intensity of the subsequent process. The process brings great inconvenience. During the drying process, the operator generally needs to continuously turn the tea leaves to observe the drying degree of the tea leaves. However, the tea leaves will be broken during the turning process, which will affect the quality of the tea leaves.
