Tea leaf de-enzyming barrel with internal heating function

Abstract

The invention discloses a tea leaf de-enzyming barrel with an internal heating function. The tea leaf de-enzyming barrel comprises a charging hole, a barrel body, a radiating pipe, a resistance heating wire, a temperature detection element and a humidity detection element, wherein the charging hole is formed in the upper part of the outer wall of the barrel body, the temperature detection element and the humidity detection element are symmetrically arranged at left and right sides of the inside of the barrel body in a symmetrical manner, the temperature detection element can detect the temperature inside the barrel body in real time, the radiating pipe is arranged at the central position inside the barrel body, and the resistance heating wire is arranged inside the radiating pipe. According to the tea leaf de-enzyming barrel, the resistance heating wire is arranged inside the barrel body, compared with the traditional barrel type tea leaf de-enzyming machine, the tea leaf de-enzyming barrel can achieve the purpose of heating inside the barrel body, so as to improve the tea leaf processing efficiency; besides, the de-enzymed tea leaves are uniform and have the high quality, and therefore, the tea leaf de-enzyming barrel has a wide application prospect.

Description

technical field [0001] The invention relates to a tea processing machinery appliance, in particular to an inner heating cylinder for tea greening. Background technique [0002] Existing tea greening machines for fixing tea leaves generally use the heat generated by fuel combustion or electric energy to fix tea leaves. High temperature is used to finish the tea leaves. In the tea making process, the existing tea greening machine has the disadvantages of high energy consumption, uneven tea greening, high technical requirements for operators, and low tea greening efficiency when tea leaves are greened. [0003] Most of the common tea cylinder-type greening machines use fuel such as coal, oil, and firewood as the heat source, and directly heat the cylinder with flames or pass the hot air generated by heating into the cylinder. As Chinese patent 92213599.1, Chinese patent 99239945.9 described cylinder body fixing machine, promptly the hot air that fuel combustion heating produc...

AI Technical Summary

Problems solved by technology

This kind of cylinder fixing machine heated by fuel combustion not only has a relatively complicated structure, but also requires additional combustion equipment, which makes the product bulky and poor in mobility, and is not suitable for small-scale mobile fixing; moreover, it relies on fuel combustion for heating, and the energy utilization rate is low, which is useless. High consumption; and because of the existence of the burning link, this kind of barrel degreening machine not only has poor operating conditions, but also has adverse effects on environmental protection and production environment, and will also affect the quality of tea leaves

In addition, the high moisture content of steamed tea leaves is not conducive to the subsequent process, and the temperature of the bottom flame is directly heated to complete the temperature is difficult to control, which will also affect the quality of tea

[0004] Chinese patent 93224114. X discloses that the cylinder body peripheral is provided with the cylinder type greening machine heated by electric heating device, although the traditional combustion heating method has been eliminated, there are still some deficiencies, such as the uneven surface temperature of the cylinder body, that is, electric heating rods ( The temperature at the wire) is significantly higher than that at the non-electric heating rod (wire), which will cause uneven finishing, resulting in burnt leaves

Secondly, the electric heating rod is directly heated, the thermal inertia is small, the temperature control is difficult, and the finishing effect is not ideal.

Furthermore, the simple electric heating consumes a lot of energy and the production cost is high, so there is still room for improvement
