Fuzhuan tea drying system and process thereof

Abstract

The embodiment of the invention relates to the technical field of tea fermentation and drying, in particular to a Fuzhuan tea drying system and a using process thereof. The Fuzhuan tea drying system comprises a drying room, the drying room comprises a room body and exhaust cavities formed in the left side and the right side of the room body, and air return openings are formed in the left side andthe right side of the room body; residual pressure valves are arranged on the outer side walls of the exhaust cavities, a plurality of air diffusers are uniformly arranged at the top of the room body,an exhaust fan and a temperature and humidity control unit are further included, air outlets of the exhaust cavities are connected with an air inlet of the exhaust fan, and two air inlets and an airoutlet are formed in the temperature and humidity control unit; and an air outlet of the exhaust fan is connected with one air inlet of the temperature and humidity control unit, and the air outlet ofthe temperature and humidity control unit is connected with the air diffusers. The Fuzhuan tea drying system and the using process thereof have the beneficial effects that the controllability is high; the production efficiency is high; and the regulation and control mode is simple, the adaptability is high, the stability is high, and the energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of tea fermentation and drying, in particular to a Fucha tea drying system and its use process. Background technique [0002] Fu tea, a characteristic product of black tea among the six major teas, is a post-fermented tea and a fully fermented tea. One of the border sales of tea was originally a special commodity in the Northwest, Kazakhstan, Mongolia and other nomadic areas. Because it is processed in Futian, it is called Fucha. Because of its effect similar to Smilax smilax, it is beautifully known as Fucha and Fuzhuan. Because it is made with official references and delivered to the government for sale, it is also called official tea and mansion tea. For the past 600 years, Fu tea was produced in Jingyang, Shaanxi. In 1958, the Tea Bureau of the National Supply and Marketing Cooperatives canceled the task of processing Fu bricks at Jingyang Fu brick factory in Xianyang, considering the secondary transp...

Problems solved by technology

It is best not to use glass jars, porcelain jars, wooden boxes or medicine jars, because these utensils are light-transmitting, not moisture-proof, and fragile

[0004] Fu tea is a kind of fermented tea, and its fermentation process is the key process of Fu tea processing. The cycle is long and the fermentation stability is poor, which is the bottleneck of Fu tea quality and cost control.

At present, the Fu tea fermentation room generally adopts the combined design of axial flow fan and heat sink. The air in the fermentation room forms layers of hot plumes from bottom to top through the action of thermal buoyancy, and then flows back through the reflection of the top of the room to form the temperature of the bottom and top. High temperature and low temperature in the middle; Secondly, there is no dehumidification facility in the fermentation room, and the moisture in the air will either absorb or surround the tea bricks with the change of temperature, resulting in poor water dissipation inside the tea bricks, which will lead to heartburn and mildew in the tea bricks thirdly, the internal energy of the air movement in the room is only provided by the cooling fins, and the movement of the air tissue cannot be controlled, and there are no rules to follow.
