Black tea oxygen introducing fermentation processing method and device

Abstract

The invention discloses a strip-shaped black tea oxygen introducing fermentation processing method and device, selected tea leaves are spread on a green feed storage tank for withering, after the withering is completed, withered leaves are obtained; the withered leaves are fully filled in a rolling barrel of a rolling machine for rolling until the cell broken rate of the withered leaves reaches more than 90% to obtain rolled leaves; the rolled leaves are evenly paved and spread in an oxygen introducing fermentation device, water vapor and oxygen are introduced into the oxygen introducing fermentation device for oxygen introducing fermentation of the rolled leaves to obtain fermented leaves; and the fermented leaves are dried to obtain the finished product. According to the method, the withered tea leaves are fully rolled, while assurance of integrity of raw materials, the cell broken rate reaches more than 90%, and subsequent fermentation speed and effect can be ensured, the rolled leaves are put into the oxygen introducing fermentation device for oxygen introducing fermentation, in the manner, while assurance of product quality, processing time can be greatly shortened, and the obtained product is tight and thin in shape, red and bright in soup color, fresh, mellow and heavy in taste, and sweet and rich.

Description

technical field [0001] The invention relates to a tea processing method and device, in particular to a black tea aerobic fermentation processing method and device. Background technique [0002] The essence of black tea fermentation is the enzymatic oxidation reaction of polyphenols in tea leaves. In the actual production process, the temperature, humidity and oxygen supply of the fermentation environment are mainly controlled to facilitate the smooth progress of enzymatic oxidation reaction of polyphenols and produce tea. flavin, thearubigin and other components that are beneficial to the quality of black tea and other aroma components. The traditional fermentation of black tea requires the construction of a fermentation room. The fermentation room requires good ventilation. The fermentation temperature is adjusted by traditional methods such as boiling water in the fermentation room and turning on the bathroom heater; the humidity is adjusted by sprinkling water around the ...
