Black tea twisting method

Abstract

The invention discloses a black tea twisting method. In the method, a twisting device is adopted, the twisting device comprises a support, a twisting plate is rotationally connected with the support, and multiple radially distributed ribs are fixedly connected with the upper surface of the twisting plate; a twisting barrel and a moving frame are arranged above the twisting plate, wherein the moving frame drives the twisting barrel to do horizontal circular motion, the twisting barrel is vertically connected with the moving frame in a sliding mode, the moving frame is provided with a hydraulic cylinder used for driving the twisting barrel to vertically move, a pressing plate is arranged in the twisting barrel, and an ejector pin is arranged on the pressing plate; a blind hole is formed in the bottom of the ejector pin, a push rod is arranged in the blind hole, a tension spring is arranged at the upper end of the push rod, an electromagnet is embedded into the lower end of the push rod, and a permanent magnet is embedded into the twisting plate, wherein the permanent magnet can be opposite to the electromagnet in a heteropolar mode. A transverse supporting plate is arranged above the twisting barrel, the upper end of the enjector pin penetrates through the supporting plate, the upper end of the enjector pin is in threaded connection with the supporting plate, and an upright rod is arranged between the supporting plate and the moving frame. By means of the method, the problem that the labor burden of workers is large when the workers twist black tea leaves is solved.

Description

technical field [0001] The invention relates to the technical field of black tea processing methods. Background technique [0002] The tea leaves used to make black tea need to be processed through rolling, so that the juice in the tea leaves can seep out, and then it is convenient for the juice of the tea leaves to contact with the air for fermentation. After the tea leaves are rolled, the juice of the tea leaves oozes out, which makes the tea leaves have a certain degree of stickiness, and the rolled tea leaves are easy to gather into a ball, thereby reducing the contact area between the tea leaves and the air, which is inconvenient for the tea leaves to ferment. The existing operation method is to place the tea leaves on the vibrating device for vibration after the tea leaves are rolled, so as to disperse the tea leaves. In this way, workers are required to carry the rolled tea leaves to the vibrating device, which increases the burden on the workers , At the same time, ...
