Abstract

This utility model discloses a tea cake pressing and impurity removal device, comprising a workbench with a sieving barrel on it. A vibrator is installed around the sieving barrel. An L-shaped connecting plate is mounted on the workbench, and an electric telescopic rod is mounted on the L-shaped connecting plate. The output shaft of the electric telescopic rod passes through the L-shaped connecting plate and is connected to a motor. A crossbeam is connected to the output shaft of the motor. Several electrostatic rods are mounted at the bottom of the crossbeam. The crossbeam and electrostatic rods are positioned directly above the sieving barrel. By controlling the low-speed operation of the electric telescopic rod and the motor, the crossbeam and the electrostatic rods mounted on it rotate synchronously at a low speed, allowing the electrostatic rods to fully contact the tea leaves. This allows for the adsorption and separation of light impurities such as hair and fine fibers contained in the tea leaves. By controlling the height between the electrostatic rods and the tea leaves, the electrostatic rods can maintain full contact with the tea leaves, thus achieving comprehensive cleaning of light impurities contained in the tea leaves and further improving the quality of the tea.
