Roll cylinder turnover type steam enzyme deactivation machine for tea production

Abstract

The invention relates to the technical field of enzyme deactivation equipment for tea production, and in particular relates to a roll cylinder turnover type steam enzyme deactivation machine for tea production. A No.1 gear is driven by a servo motor, and a No.2 gear drives a No.2 rotating shaft to rotate through gear meshing to make a semi-bevel gear intermittently drive two symmetrical driven bevel gears to rotate, so that a No.1 rotating shaft rotates in a reciprocating manner; moving blocks are closer to or farther away from each other along a threaded section, so that a folding rod is unfolded or folded to drive a lifting plate to move up and down, a left gear and a long rack act to produce rotation, and a roll cylinder is turned over through a No.3 rotating shaft; at the same time, aright gear and a short rack intermittently act to make a main pipe swing in a reciprocating manner, so that tea is prevented from being stuck to the pipe, and a steam guide pipe is prevented from being knotted with the rotation; and steam of the steam guide pipe is introduced into the main pipe and is discharged through steam outlet holes of branch pipes, and through cooperation with the turning of the roll cylinder, the tea leaves and the steam are in full contact to realize rapid and uniform enzyme deactivation.

Description

technical field [0001] The invention relates to the technical field of de-greening equipment for tea production, in particular to a drum-turning steam de-greening machine for tea production. Background technique [0002] Tea, (scientific name: Camellia sinensis (L.) O.Ktze.), shrub or small tree, twigs glabrous. Leaves are leathery, oblong or elliptic, with blunt or sharp apex, cuneate base, shiny upper surface, glabrous or pilose at the beginning, serrated edges, petiole glabrous. Flowers white, petiole sometimes slightly longer; sepals broadly ovate to round, glabrous, persistent; petals broadly ovate, base slightly conjoined, back glabrous, sometimes pubescent; ovary densely white haired; style hairless. Capsules 3-globose or 1-2 globose, 1.1-1.5 cm high, with 1-2 seeds per bulb. The flowering period is from October to February of the following year. [0003] The wild species is widely found in the mountainous areas of the provinces south of the Yangtze River in China...

Problems solved by technology

[0009] However, many traditional drum-type greening machines still use heating devices to directly heat the drum, which can easily cause local temperature to be too high and overheating, resulting in uneven heating, uneven heating of tea leaves, and affecting the quality of tea; Coordinated degreening machine, but there are situations where the tea leaves and steam cannot be fully contacted, and the tea leaves are easy to remain on the steam pipeline
