Black tea fermentation device

Abstract

The invention relates to a black tea fermentation device, which comprises a fermentation tank, a motor, a speed reducer, a pinion, a large gear, a bottom plate, a spring, a frame, a rotating shaft, a rotating shaft support seat and a vibrator. The top surface of the fermentation tank has a fermentation tank opening, A fermentation box cover is installed on the mouth of the fermentation box, and a moisture discharge hole is opened on the fermentation box. The fermentation box is installed on the frame through the rotating shaft and the rotating shaft support seat, the motor is connected with the reducer, and a pinion is installed on the output shaft of the reducer. A large gear is installed on the rotating shaft, and the large gear meshes with the small gear. The vibrator is mounted on the frame, and the frame is mounted on the base plate through a spring. The present invention carries out necessary vibration and turning during the tea fermentation process, that is, the tea leaves in the fermentation box are automatically turned over by an electric motor, so that the tea leaves can be fully dehumidified and fermented, and the tea leaves are spread out evenly by a vibrator to ensure that the tea leaves are fermented. The thickness of the spread in the box is consistent, which ensures that the black tea has a good uniformity and consistency during fermentation.

Description

technical field [0001] The invention relates to a fermenting device, in particular to a black tea fermenting device. Background technique [0002] Fresh leaves are fermented, which is an important process in the primary production process of black tea. At present, many black tea fermentation devices used by black tea production enterprises are equipped with multiple tea storage drawers arranged up and down in the cabinet with a moisture supply and heating system. The tea leaves are fermented in the drawers. In order to make the tea leaves ferment evenly, generally manual It is difficult to evenly stir the tea leaves manually by opening the box, so it is difficult to ensure the quality of the tea leaves in this type of fermentation device. The invention patent with the Chinese patent number 201220289785.5 discloses an automatic turning device for a black tea fermentation machine. The turning device uses two adjacent layers of conveyor belts with opposite rotation directions ...

Problems solved by technology

At present, many black tea fermentation devices used by black tea production enterprises are equipped with multiple tea storage drawers arranged up and down in the cabinet with a moisture supply and heating system. The tea leaves are fermented in the drawers. In order to make the tea leaves ferment evenly, generally manual Open the box and turn the tea leaves. It is difficult to evenly turn the tea leaves manually, so it is difficult to ensure the quality of the tea leaves with this type of fermentation device.

The invention patent with the Chinese patent number 201220289785.5 discloses an automatic turning device for a black tea fermentation machine. The turning device uses two adjacent layers of conveyor belts with opposite rotation directions to make the tea leaves fall from the upper layer of conveyor belts to the next layer for transportation. Bringing the function of tea flipping, because the number of layers of the conveyor belt is limited, it is difficult to turn all the tea leaves evenly by this simple method of free fall of tea leaves, and it is difficult to spread the tea leaves on the conveyor belt The thickness is consistent, so the patent cannot guarantee the quality of uniformity and consistency of black tea after fermentation
