Fermentation device for black tea production

Abstract

The invention discloses a fermentation device for black tea production, and relates to the field of black tea fermentation. According to the fermentation device for black tea production, the inner side wall of an equipment box is rotatably connected with carrying boards, the upper surface of the equipment box is fixedly connected with a feeding hopper, a fan is fixedly connected with the upper surface of the equipment box and located on the side surface of the feeding hopper, wind guide tubes are fixedly connected to two sides of the fan, the ends, away from the fan, of the two groups of windguide tubes respectively communicate with the inner walls of the two sides of the equipment box, an electric heating tube is fixedly connected with the side surface of one group of wind guide tubes, and a humidifier is fixedly connected to the outer surface of the other group of wind guide tubes. According to the fermentation device for black tea production, by adjusting blocking strips on two sides, the electric heating tube and the humidifier alternately heat and humidify the wind generated by the fan to heat the inside of the equipment box, so that each layer of the carrying board inside the equipment box can be heated and humidified evenly, and meanwhile, ventilation can be always kept in the fermentation process.

Description

technical field [0001] The invention relates to the technical field of black tea production equipment, in particular to a fermentation device for black tea production. Background technique [0002] Black tea is made of suitable tea tree buds and leaves as raw materials, and is refined through a series of processes such as withering, rolling, fermentation, and drying. During the processing, a chemical reaction mainly enzymatically oxidized by tea polyphenols occurs. The chemical composition changes greatly, tea polyphenols are reduced by more than 90%, new components such as theaflavins and thearubigins are produced, and the aroma substances are significantly increased compared with fresh leaves. [0003] The fermentation process is a key step in the production process of black tea. During the fermentation process of black tea, it is necessary to artificially control the temperature, humidity, ventilation and fermentation time of black tea to achieve the best effect of fermen...

Problems solved by technology

[0003]The fermentation process is a key step in the production process of black tea. During the fermentation process of black tea, it is necessary to artificially control the temperature, humidity, ventilation and fermentation time of black tea. In order to achieve the best effect of fermentation, and now many black tea fermentation equipment adjust the humidity and temperature, because the vents are generally set at the top or bottom, resulting in a single airflow direction, it is easy to appear that the tea near the air inlet is wet, and far away The humidity of the tea leaves in the air inlet is not enough, which makes the quality of the tea vary greatly. Moreover, the general fermentation room is set up as a clapboard type. It is necessary to manually put the tea on the fermentation plate, and then put the fermentation plate on the clapboard. The box is too short, the number of partitions is not enough, the amount of single fermentation is small, and the output is low. If there are too many partitions, the equipment box will be too high, and it will be cumbersome to insert the fermentation plate into the high partition.
