Roller far infrared tea green-removing machine

Abstract

The invention provides a roller far infrared tea green-removing machine, which comprises bases, a driving device, a coupler, a bearing device, a roller, a radiating element, a feed hopper and a discharge hole. The tea green-removing machine is characterized in that: bearing bases are fixed to the tops of supports; both ends of a revolving shaft of which the middle part is provided with a carrier roller with a trapezoid groove are arranged in bearing base holes by bearings; chain wheels are arranged at the extending ends of a driving shaft and a driven shaft in the revolving shaft; the same chain is hung on the two chain wheels; the outermost extended end of the driving shaft is connected with the output end of the driving device by the coupler; a driving carrier roller mechanism and a driven carrier roller mechanism are arranged on the top of the support I of which the bottom is fixed on the base I simultaneously, and two groups of bearing carrier roller mechanisms are arranged on thetop of the support II of which the bottom is fixed on the base II simultaneously; both ends of the roller are supported in the trapezoid groove of the carrier roller by a roller wheel; and a feed hopper is arranged at the feed end of the roller, the discharge hole is formed at the other end of the roller, and the far infrared radiating element is arranged in the center of the roller. The roller far infrared tea green-removing machine has good green-removing effect, and is favorable for the subsequent forming and drying of tea.

Description

technical field [0001] The invention provides a drum-type far-infrared tea degreening machine, specifically a device for degreening fresh tea leaves by heating with far-infrared radiation. Background technique [0002] Drying of tea is very important. Its purpose is: first, to destroy the activity of enzymes, inhibit enzymatic oxidation, promote the internal thermochemical reaction of tea, improve the aroma and taste, and fix the inner quality and shape of tea; second, reduce the moisture content of fresh tea leaves , so that it is not easy to undergo qualitative changes, so that it can be stored and transported. Green tea is a kind of tea made from suitable new shoots of tea trees as raw materials, which are processed by killing, rolling, and drying. It has rich nutritional components and good health care effects. Fixing is the first process of green tea drying. The picked young leaves are subjected to high temperature to destroy the activity of enzymes, inhibit fermentati...

AI Technical Summary

Problems solved by technology

Greening is the key process to ensure the color, aroma, taste and shape of tea leaves. If the greening effect of fresh leaves is not good, high-quality tea cannot be produced.

During the greening process, the temperature control is very important. If it is too high, the water will evaporate too much, causing the tea to be browned, which will directly affect the color of the tea; if it is too low, there will be too much water remaining, which will affect the taste of the tea.

[0003] However, the tea greening machines commonly used in the market currently use coal, firewood, oil, etc. as heat sources for heating, and the temperature of tea greening is difficult to control.

There are also fixing equipment that use far-infrared as a heat source, but far-infrared radiation heats the drum, and the temperature is still difficult to control

In addition, in the traditional tea making process, the quality of the greening effect is generally determined by the tea maker based on experience, and parameters such as the temperature and time of the greening are also completed entirely by experience.

Therefore, it is easy to cause the finished tea to be not emerald green enough, the bottom of the leaves not bright enough, and the tea taste not fresh enough
