Tea withering machine

Abstract

The invention discloses a tea withering device in the field of tea production equipment. The tea withering device comprises a withering groove, and the bottom face of the withering groove is connected with a cavity used for conveying hot air; the upper end face of the cavity is seamlessly attached to the bottom face of the withering groove, the bottom face of the withering groove and the upper end face of the cavity are each densely provided with ventilation holes, and the ventilation holes enable the withering groove to be communicated with the cavity; the outer wall of the cavity is provided with connecting holes penetrating through the outer wall, and the ventilation holes are connected with a hot-air blower; a netted tea spreading net is laid on the inner wall of the withering groove. According to the tea withering device, the cavity is arranged, so that hot air generated by the hot air blower has to wither tea leaves through the cavity, heat waste is avoided, and meanwhile tea withering quality is improved; the tea spreading net is arranged, so that after the tea leaves are withered, the tea spreading net can be tightened, the tea leaves are collected in the tea spreading net at a time, and tea collection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of tea production equipment, in particular to a tea withering device. Background technique [0002] Withering is the process of spreading the picked fresh leaves evenly according to a certain thickness, and drying them in the sun to make the fresh leaves appear wilting; physical and chemical reactions will occur during the withering process of tea leaves. When the tea leaves wither, the water decreases, which makes the stems and leaves of the tea wilt, the grass gas is lost, and the leaf color changes from bright green to dark green; at the same time, due to the dehydration and respiration of the withered tea leaves, the permeability of the cell membrane increases. , the enzyme activity contained in the leaves is enhanced, the macromolecular substances protein, starch, and insoluble protopectin substances in the leaves begin to degrade, and the small molecule glucose, amino acids, soluble pectin and other substances t...

AI Technical Summary

Problems solved by technology

[0005] The present invention intends to provide a tea withering machine to solve the problems in the prior art that the heat utilization rate is low due to the fan directly transporting the heat to the withering trough and the tea leaves are directly laid in the withering trough, which makes it inconvenient to collect the tea leaves
