Fixation device and fixation method of tea leaves

Abstract

The invention discloses a fixation device and fixation method of tea leaves. The water removing device of the tea leaves comprises an inner cylinder and an outer cylinder, wherein a spiral blade-guiding plate is arranged in the inner cylinder; a controller is arranged on the outer cylinder; a tea leaf inlet is formed in one side of the inner cylinder, and a tea leaf outlet is formed in the other side of the inner cylinder; a heating device is arranged under the outer cylinder; a heat insulating plate is arranged between the heating device and the outer cylinder; each sensor is arranged in thewater removing device; and a temperature and humidity sensor, a pressure sensor and a mechanical device are all connected with the controller. The water removing method of the tea leaves comprises thefollowing steps of firstly, starting the water removing device, and preheating the inner cylinder until the temperature of the inner cylinder is preheated to 265-275 DEG C; then putting the tea leaves in the inner cylinder, and performing fixation, wherein time for fixation is 5-10 minutes; and finally, opening the tea leaf outlet, and guiding the tea leaves through the spiral blade-guiding plateout, so as to complete fixation. Through the adoption of the water fixation and the fixation method disclosed by the invention, the intelligent fixation device is realized, and according to the device, the fixation method is also provided, so that the process of fixation is simple and convenient; and according to situations, fixation can also be performed on the different kinds of tea leaves.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a greening device and a greening method for tea. Background technique [0002] The drum type degreening machine has long been an indispensable key equipment in the green tea primary production process. It consists of a special stove and a cylindrical drum inside. Six spiral guide vanes are distributed longitudinally on the inner wall of the drum. The axial helix angle The inclination angle and radial angle are both 24°, and the finalized dimensions of the drum are: 65 cm in diameter and 330 cm in length. The 650-J drum type degreening machine developed by Judong Agricultural Machinery Factory and promoted and used in China belongs to this type. Using this kind of degreening machine for green tea processing is to put the fresh tea leaves to be processed into the drum with a temperature of 200-280 ° C. With the rotation of the drum, the tea leaves will roll, throw and advance along th...
