Roller type fresh leaf screening machine for making tea

Abstract

The invention discloses a roller type fresh leaf screening machine for making tea. The roller type fresh leaf screening machine comprises a lifter, a vibratory feeder, a combined roller screen and a driving mechanism. The combined roller screen is provided with a frame and four roller screen bodies, wherein the four roller screen bodies are each of a cylindrical structure, each roller screen body is divided into four layers which are sleeved from inside to outside, the lengths are gradually reduced from inside to outside, and the diameters are gradually increased from inside to outside. The four roller screen bodies are different in screen hole size, the size of screen holes at the innermost layer is the largest, and the sizes of screen holes are reduced from the innermost layer to the outside layer by layer. The four roller screen bodies are overlapped, fresh leaves are screened according to different features of single buds, one bud with one leaf, one bud with two leaves, one bud with three or four leaves, and single pieces, and thus graded screening of the fresh leaves is achieved. A variable-frequency motor is adopted to achieve stepless regulation, and the roller type fresh leaf screening machine is simple in structure, easy to operation and suitable for application and popularization.

Description

technical field [0001] The invention belongs to the field of tea equipment, in particular, it relates to a drum-type fresh leaf screening machine for making tea. Background technique [0002] The traditional tea sieving machine is mainly used for the selection of finished tea. The moisture content of the finished tea is about 6%. It is a granular structure with less intertwining and hooking. The current round sieve, shaking sieve, etc. are not effective in grading machine-picked fresh leaves. Due to the high water content of machine-picked fresh leaves, machine-picked fresh leaves are single buds, one bud and one leaf, one bud and two leaves, and one bud. Mixtures of three or four leaves, single sheets, etc., are intertwined and connected with each other, and their fluidity is not good. It is difficult to classify these five-stage fresh leaves with current round sieves, shaking sieves, etc. The present invention is to design a method for The purpose of the fresh leaf drum s...

AI Technical Summary

Problems solved by technology

The current round sieve, shaking sieve, etc. are not effective in grading machine-picked fresh leaves. Due to the high water content of machine-picked fresh leaves, machine-picked fresh leaves are single bud, one bud and one leaf, one bud and two leaves, and one bud. The mixture of three or four leaves, single sheets, etc., are intertwined and connected with each other, and the fluidity is not good. It is difficult to classify these five grades of fresh leaves with the current round sieve, shaker sieve, etc. The present invention is to design a method for The purpose of the fresh leaf drum sieving machine for grading fresh tea leaves is to divide the fresh leaves into the above five grades of fresh leaves
