Method for facility TanTsing (first procedure of tea processing, by laying fresh tea on winnowing forks or ground to lose moisture and get rid of the smell of grass in the tea) of tea leaves

Abstract

The invention relates to a method for the facility TanTsing of tea leaves, which is realized by specific equipment and a matching process thereof in a heating chamber. By the control of the conditions of an air conditioner, a dehumidifier, an ultrasonic atomizer and a fan, the precise regulation and control of the humiture condition of the TanTsing chamber and the effective regulation of environmental gas, the purpose of the proper TanTsing of the fresh leaves is achieved. The invention can realize the precise regulation and control of the humiture, the gas circulation and the like of a TanTsing space, further regulate and control the approach and the degree of a physical and chemical reaction of the fresh leaves under a specific micro-area environmental condition and realize the regulation of gas in a micro-area environment, thereby inducing the beneficial transformation of the contained components and providing a better material basis for a subsequent processing procedure.

Description

technical field [0001] The invention belongs to the field of food processing methods, relates to tea processing technology, and in particular relates to a facility-spreading method for tea. Background technique [0002] Spreading green tea is the first process in the traditional tea processing process, and it is also an extremely important process. Proper greening can promote the gradual loss of water in fresh leaves, the slow change of endoplasmic components, the shrinkage of leaf area, and the change of leaf quality from hard to soft. , the leaf color changes from bright green to dark green, and the fragrance also changes accordingly, which provides a good basic condition for the subsequent process. [0003] At present, there are four main ways of spreading in production. A better way is to build a multi-layered shelf (steel or bamboo wood structure), and put tools such as a soft plaque, a basket or a wooden tray with a wire mesh to spread it out. On the one hand, it can ...

Problems solved by technology

A better way is to build a multi-layered shelf (steel or bamboo-wood structure), put soft plaques, bamboo baskets or wooden trays with wire mesh and other tools for spreading, on the one hand, it can keep the fresh leaves away from the ground, At the same time, it also saves the area occupied by fresh leaves; another way is to spread bamboo mats on the ground or directly put soft plaques, bok baskets, etc., and then spread fresh leaves on it. This method is a traditional method and is the most widely used. Widely used, but the hygienic condition of fresh leaves cannot be guaranteed; the worst way is to spread fresh leaf raw materials directly on the ground or on materials that do not meet hygienic requirements. This method is extremely primitive and backward, and not only cannot guarantee the hygienic quality of fresh leaves , and it will have a serious negative impact on the entire tea industry, which must be strictly prohibited; the fourth is to use a specific greening equipment - spreading silage machine for spreading.

The first three spreading methods can only use the temperature and humidity conditions of the natural environment, and cannot effectively control the temperature and humidity through artificial means

Although the fourth way of spreading can obtain suitable environmental temperature and humidity conditions through equipment adjustment, due to the small space, the amount of spreading of fresh leaves is limited, and it is difficult to meet the production demand during the peak period of tea making. The exchange of gas affects the quality of green leaves to a certain extent
