Fermentation device for producing keemun black tea

Abstract

The invention relates to the technical field of black tea processing, in particular to a fermentation device for producing keemun black tea. The device comprises a housing, a rotating shaft, a motor,and a second heating plate. The left end surface of the housing is fixedly connected with a heating device. The upper end surface of the housing is fixedly connected with a motor, the end of the motormain shaft is fixedly connected with a rotating shaft, a lower surface of the rotating shaft is rotatably connected with a partition plate, vertically and uniformly distributed fixing devices are fixedly connected to the outer side of the rotating shaft, a jet device is rotatably connected to the central portion of the rotating shaft, the left end surface of the jet device is fixedly connected tothe heating device, a temperature sensor is fixedly connected to the left end surface of the housing, and a humidity sensor is fixedly connected to the right end surface of the housing. In the invention, through the arrangement of the heating box, the first heating plate, a fan, an air duct and a spiral tube, the temperature and humidity of the housing can rise rapidly, the fermentation efficiency can be accelerated, and time can be saved. The fermentation device has good practical benefit, and is worth of popularization and usage.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a fermentation device for producing Keemun black tea. Background technique [0002] Keemun black tea can provide rich riboflavin, folic acid, carotene, tocopherol and phylloquinone, and is an important source of fluoride in food. The production process of black tea mainly includes picking, withering, rolling, deblocking, fermentation, Drying and other steps, fermentation is the last and key step in the production of black tea. The key factors in the fermentation process of black tea are the temperature and humidity of fermentation. In recent years, various mechanized production processes of black tea have become more common. The fermentation process is to form black tea The key process of color, aroma and taste quality characteristics, with the development of society, the demand for black tea is getting higher and higher, therefore, the demand for a fermentation device for...

Problems solved by technology

[0003] Improvement of a fermenting device for black tea production invented by Chinese Patent Application No. 201811224355.3. Chinese Patent Application No. 201811224355.3 is heated by pumping external air into the heating chamber for heating through a heating block and then transporting it into the box. This setting It cannot be guaranteed that all the air drawn in will be heated by the heating block, and it is very likely that it will be directly transported into the cabinet through the air guide pipe. It cannot guarantee that the air will be heated, so that the temperature of the cabinet cannot be guaranteed, and there is also a Chinese patent application for humidification No. 201811224355.3 is humidified through the air duct, because the air duct is located below the entire equipment, the transport efficiency is relatively slow during the upward transport of moisture, and there are fermentation sieves blocking it, resulting in different degrees of fermentation of tea leaves in the upper and lower fermentation sieves, resulting in different quality , there is also a device without a fixed device. When the motor is rotating, the fermentation sieve may shake, tilt and dump, which seriously affects the quality of fermentation. Therefore, a fermentation device for Keemun black tea production is proposed to solve the above problems.
