Abstract

The invention belongs to the technical field of tea leaf processing equipment, and particularly discloses a tea leaf screening device which comprises a base, a support, a screening bucket, a motor andan ejector rod. The upper portion of the screening bucket is provided with a feed inlet, the upper portion of the support is provided with a discharging hopper, and the discharging hopper is providedwith a discharging outlet right opposite to the feed inlet; multiple layers of screening plates are arranged in the screening bucket from top to bottom, the position, located above each screening plate, of the screening bucket is provided with a discharge outlet, the upper end of an output shaft of the motor is provided with a supporting rod rotationally connected with the output shaft, a pistonhead is arranged on the supporting rod, the piston head is in sliding sealed connection with the inner wall of the screening bucket, the position, located above the piston head, of the screening bucket is provided with a first one-way valve which communicates with the interior of the screening bucket in one way, and the discharge outlet is provided with a second one-way valve which communicates with the exterior o the screening bucket in one way. The tea leaf screening device is mainly used for screening tea leaves, and the problems that size distribution of screened tea leaves is not uniformand the tea leaf separation effect is poor due to the large feeding amount are solved.

Description

technical field [0001] The invention belongs to the technical field of tea processing equipment and specifically discloses a tea screening device. Background technique [0002] After the tea leaves are initially processed, their quality characteristics have been basically formed. However, due to the scattered primary production of tea leaves, the different tenderness of picking, and the differences in primary processing techniques, the quality specifications of raw tea are complicated. In order to increase the commodity value of tea and standardize product quality, fine manufacturing must be done to meet the needs of the domestic market and finally meet the requirements of consumers. [0003] The technological process of tea refining varies with different types of tea, and the same kind of tea, the technological process of each tea factory is also different. But its purpose is generally the same, mainly: trimming the shape, dividing into patterns and colors, separating old...
