Tea dryer based on roller stir-frying technology

Abstract

The invention discloses a tea dryer based on a roller stir-frying technology. The tea dryer comprises a box body and a drying roller; a dustproof net, a drying roller and a second flow guide plate aresequentially arranged in the inner cavity of the box body from top to bottom, wherein the top end of the box body communicates with an exhaust pipe, and the drying roller is rotationally connected tothe box body through a rotating shaft; a discharging port coordinated with a guide hopper is formed in the lowest end of the rotating shaft, a feeding port is formed in the other end of the rotatingshaft, and one end of the feeding port communicates with the drying roller in a penetrating mode; multiple through holes are uniformly formed in the second flow guide plate; multiple supporting legs are uniformly arranged at the bottom end of the box body, and a supporting pressing plate is arranged between every two supporting legs; and a purification box is arranged at the top ends of the supporting pressing plates. According to the tea dryer, high-temperature gas enters an air injection device through the purification box, then enters the box body through air nozzles, tea leaves in the drying roller are dried, and then are rolled continuously along with the rolling of the drying roller, so that the tea leaves are heated more uniformly, the loss of the tea leaves can be reduced, and occurrence of the broken tea leaves can be reduced.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a tea drying machine based on the drum stir frying technology. Background technique [0002] Tea, shrubs or small trees, young branches 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. The wild species is widely found in the mountainous areas of the provinces south of the Yangtze River in China. It is a small tree shape with large leaves, often more than 10 cm long....

AI Technical Summary

Problems solved by technology

[0004] Tea drying is the last link of tea frying, and it is also a necessary process, which can further reduce the moisture content of tea to less than 7%, so as to facilitate the preservation and quality assurance of tea. Labor intensity is high, production efficiency is low, and sanitary conditions are poor. W
