1.Vibro sifter

 The vibro sifter is used as an excitation source by an upright motor. When the vibro sifter is started, the eccentric weights installed on the upper and lower ends of the motor convert the rotary motion of the motor into a horizontal, vertical, and inclined three-dimensional motion. The movement is transmitted to the screen surface. In this process, the fine slag of tea leaves smaller than the pore size of the sieve surface falls through the sieve hole to the lower layer, and becomes the undersize material. The tea leaves larger than the pore diameter of the sieve surface are discharged from the discharge opening after continuous jumping movement, and the weights of the upper and lower ends are adjusted by adjusting The phase angle of the hammer can change its trajectory on the screen surface to achieve the purpose of screening.

Dahan vibro sifter  has high screening efficiency, the screen is not blocked, the powder is not flying, the sieve is fine to 500 mesh (28 microns), and can be designed with 1~5 layers of screen surface according to the screening yield of tea leaves. The fully enclosed structure has no dust and dust during the tea screening process, and is equipped with a special screen cleaning device (bouncing ball), which can reduce the problem of blockage of the tea during the screening process and improve the screening effi
