The purpose of tea rolling is to make the initial shape, and to break the leaf cells to increase the flavor concentration of the finished tea. In green tea processing, except for a few famous green teas, rolling is generally an indispensable process.

Common failures, causes and solutions of tea kneading machines:

(1) The kneading bucket does not rotate or reverse. The reason for the non-rotation is that the head screw between the active crank arm and the active shaft is loose, and the motor output V-belt is loose and slipping. The reason for the reverse rotation is the wrong three-phase electrical connection of the motor. The solutions are: tighten the head screw, tighten or replace the V-belt; exchange any two input power cables of the motor.

(2) The running noise is loud. The reasons include insufficient lubricating oil in the gear reducer, wear of the gears in the reducer, and the motor fan touching the shell. The solutions are: add enough lubricating oil, replace gears, and adjust the fan housing;

(3) The kneading lid of the single-arm kneading machine collides with the kneading barrel. The reasons are that the fastening bolts at the lower end of the single-arm column are loose, and the connecting screws between the gland and the gland are loose. The solution is: tighten the loose screw.
