Drum type tea greening machine

Abstract

The invention discloses a drum-type tea degreening machine, which relates to the technical field of tea production equipment, comprising a frame, a drum and a drum shell fixed on the frame, the drum includes an inner wall of the drum and an outer wall of the drum, and the inner wall of the drum is made of microporous materials As a result, a heating layer is provided on the outer side of the inner wall of the drum, guide vanes are provided on the inner side of the inner wall of the drum, and an air cavity is arranged between the heating layer on the outer side of the inner wall of the drum and the outer wall of the drum. The present invention controls the change of the pressure through a proportional valve, adjusts the pressure of the gas entering the drum, thereby changing the thickness of the gas film; pulses control the pressure of the gas entering, and realizes the intermittent contact between the tea leaves, the drum and the guide vanes. The magnitude of the amplitude controls the contact distance between the tea and the cylinder wall, and the frequency and duty cycle control the length of the contact time, which not only improves the efficiency of green removal, but also prevents burnt edges and other phenomena that affect the quality of tea.

Description

technical field [0001] The invention relates to the technical field of tea production equipment, in particular to a drum-type tea greening machine. Background technique [0002] The main function of greening is to destroy and passivate the oxidase activity in fresh tea leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make tea soft, easy to knead and form, and at the same time emit Green smell, promote the formation of good aroma. Fixing is a very important process in tea processing. [0003] Today's tea leaves are hand-fried and machine-fried to form. Although the quality of hand-fried tea leaves is good, the efficiency is low, fragile, and green tea leaves are wasted. With the continuous update of tea-frying equipment, semi-automatic home-use tea-frying machines are becoming more and more popular, which brings convenience and convenience to the majority of tea farmers.

Problems solved by technology

[0005] The present invention aims to solve the shortcomings of the prior art that the degree of intelligence of the tea greening machine is not high, the production product is single, the degree of control in the production process is not high, and the color and aroma of the tea have not reached the optimal state, and an energy-saving intelligent machine is proposed. Tea degreening technology and system, using electromagnetic induction and hot air combined with high-efficiency heating technology, designed a new type of tea degreening drum structure and an intelligent control system for degreening, greatly reducing energy consumption during the degreening process, providing a drum-type tea degreening machine with high efficiency and quality
