Rolling mechanism for enzyme deactivation of tea leaves

Abstract

The invention relates to the field of tea processing, in particular to a rolling mechanism for enzyme deactivation of tea leaves. The rolling mechanism comprises a machine frame, a rolling barrel anda pressing disc, wherein the rolling barrel is fixedly connected with the machine frame, two vertical plates are fixedly connected with the machine frame, a moving frame is arranged between the two vertical plates, the left and right two sides of the moving frame are fixedly connected with sliding rods, the sliding rods are horizontally connected with the vertical plates in a sliding manner, firstcompression springs are connected between the left and right two sides of the moving frame and the vertical plates, a vibration block is vertically connected in the moving frame in a sliding manner,second compression springs are connected between the upper and lower two sides of the vibration block and the moving frame, motors are fixedly connected with the vibration block, eccentric blocks areconnected with the motors, a vertical rod is fixedly connected with the vibration block, the top of the vertical rod is fixedly connected with a rolling plate located below the rolling barrel, and twoends of the rolling plate are provided with material outlets. The solution improves the rolling degree of tea leaves, and makes the tea leaves be more fully rolled.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a rolling mechanism for tea greening. Background technique [0002] In the production process of tea, rolling is an essential step in tea processing. The main function of rolling is to knead the finished tea leaves into strips, so as to keep the tea fiber tissue from being damaged. In addition, rolling can destroy the tissue cells of tea leaves, making The substances contained in the tea penetrate into the surface of the tea, which can increase the brewing concentration of the tea when brewing the tea. [0003] At present, the rolling of tea leaves is mainly carried out on the kneading machine. The existing kneading machine is mainly equipped with a circular kneading disc, kneading barrel, gland, motor, crank and connecting arm, etc. When kneading, the tea leaves are put into the kneading bucket In the middle, the gland squeezes the tea leaves in the kneading barrel, the motor driv...

Problems solved by technology

[0004] But the existing kneading machine has the following disadvantages: 1. The motor drives the kneading barrel to move through the crank and the connecting arm. Since tea leaves are housed in the kneading bucket, the weight of the kneading bucket is relatively large, and the rotation of the kneading bucket driven by the motor is laborious, so the output of the motor The power is relatively large, which consumes more energy, and requires multiple motors to drive. The number of motors is large, and the cost of the kneading machine is relatively high; It can be kneaded in one direction, but the tea is not fully kneaded, and the degree of tea kneading needs to be improved; 3. After kneading, there will be debris, soil and other impurities in the tea leaves, and additional screening is required. During the kneading process Screening cannot be achieved in the process, the process is complicated, and it is a waste of time
