Tea baking machine and hot air exhaust method thereof

Abstract

The invention relates to the mechanical field of tea, in particular to a tea baking machine and a hot air exhaust method thereof. The tea baking machine comprises a cylinder with an inner cavity, anda heating module arranged in the inner cavity; and a hot air outlet communicating with the inner cavity is formed in the top of the cylinder. The tea baking machine is characterized in that the side wall of the cylinder is hollowed; the hollowed part forms a ventilation way; a ventilation port communicating with the ventilation way is formed in the outer wall near the top of the cylinder; the ventilation port is connected with an air blower; an air guide port communicating with the inner cavity is formed in the connecting place of the ventilation way with the side wall, near the bottom, of thecylinder; and a spiral air guide plate extends in the ventilation way from the ventilation port to the air guide port at the bottom of the cylinder in the peripheral direction of the cylinder. The hot air exhaust method comprises the steps of hot air manufacturing, hot air recovery and sequential repeated conduction of the two above steps. The tea baking machine has the beneficial effects of lowself temperature of the cylinder, capability of recovering energy, high resource utilization rate and low energy consumption.

Description

technical field [0001] The invention relates to the field of tea machinery, in particular to a tea baking machine and a hot air outlet method thereof. Background technique [0002] Baking is a very important process in the tea making process, it is related to the quality of tea; baking is to use high temperature to dry tea, so that the tea is easy to store; tea baking machine is used for baking and frying tea. In the prior art, in order to achieve the effect of roasting tea leaves, the tea leaves are placed on the top of the roasting machine, a heating wire is arranged inside the roasting machine, and the hot air at the bottom of the roasting machine is transported to the top of the roasting machine by a blower, so that The hot air is transported to the top of the barrel, so that the tea leaves can be roasted and stir-fried. [0003] Although the tea roasting machine described in the above structure can dry the tea leaves, the roasting machine is usually made of high temper...

AI Technical Summary

Problems solved by technology

[0003] Although the tea roasting machine described in the above structure can dry the tea leaves, the roasting machine is usually made of high temperature resistant metal material because the inside of the roasting machine is provided with a heating device. Although the metal is resistant to high temperature, the metal also has Strong thermal conductivity, so there is a disadvantage of poor thermal insulation effect; due to its poor thermal insulation effect, the outer wall of the roaster will have a high temperature during the working process of the roaster, which poses a certain threat to the life safety of the staff , so there is also the disadvantage of poor safety performance; secondly, due to its fast heat dissipation, it is usually necessary to heat the temperature of the heating device to a temperature much higher than the temperature of the required roasted tea leaves, so that the top of the roaster will have a The standard temperature of dry tea, so there are still disadvantages of low resource utilization and high energy consumption
