Fresh tea winnowing machine for tea production

Abstract

The invention discloses a fresh tea winnowing machine for tea production. The machine comprises an elevator, a vibration conveyor and two parallel winnowing chambers. Blind windows capable of automatically adjusting blade angles are arranged at the tops of the winnowing chambers; air blowers and air suckers are respectively arranged at the front parts and the back parts of the winnowing chambers; vibration screens and conveying belts are arranged at the bottoms of the winnowing chambers; after two times of winnowing are performed for fresh teas by the first and second two winnowing chambers, tea with one bud and three / four leaves falls in a first-area vibration screen on the front side, tea with one bud and two leaves falls into a second-area vibration screen, tea with one bud and one leaf falls into a third-area vibration screen, single tea and bud heads are blown to the back side to fall in a fourth-area vibration screen; and the classified fresh tea falls into the corresponding conveying belts on the lower side for delivery from gaps of stainless steel rods of the different vibration screens to realize classified winnowing of the fresh tea. The machine is precise in winnowing, adopts a variable frequency motor to realize intelligent adjustment, and is simple in structure, liable to operate and suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of tea equipment, in particular, it relates to a fresh leaf winnowing machine for making tea. Background technique [0002] The traditional tea winnowing machine is mainly used for finished tea winnowing when it is used in tea processing. The finished tea has a moisture content of about 6%. It is a granular structure with less intertwining and hooking and good fluidity. Eliminate the light leaves, floating leaves and burnt leaves, etc., and the effect is good; the winnowing machine used for tea generally adopts horizontal blowing, the airflow direction is horizontal, and the tea stays in the air for a short time, but due to the light leaves, floating leaves and burnt The specific gravity of the leaves is quite different from that of denser tea leaves, which can play a sorting effect. The current winnowing machine is used for the classification of machine-picked fresh tea leaves, and the effect is poor. Due to the hig...

AI Technical Summary

Problems solved by technology

The current winnowing machine is not effective when used for grading machine-picked fresh tea leaves. Due to the high water content of machine-picked fresh tea leaves, the fresh leaves of machine-picked tea are single bud, one bud and one leaf, one bud and two leaves, one bud and three four leaves A mixture of , monolithic, etc., they are intertwined with each other, and the fluidity is not good. It is difficult to classify these five grades of fresh leaves with the current air separator. The present invention is to design a fan for grading fresh tea leaves The purpose of the selection machine is to use the designed fresh leaf winnowing machine to divide the fresh leaves into the above-mentioned graded fresh leaves
