Problems solved by technology

The existing tea sorting machine has a single air selection method, which is difficult to adapt to various tea types and other sorting requirements
Moreover, during the transportation of tea, there will be some light flake debris mixed in, such as irregular pieces of paper peeled off from the cardboard box. These cardboards are entangled with the tea mosaic, and it is difficult to sort them out by ordinary color sorting. Therefore, , it is urgent to develop an efficient color sorting and winnowing machine to sort tea leaves and improve the quality of tea leaves

Embodiment Construction

[0021] Do further description below in conjunction with accompanying drawing:

[0022] Such as figure 1 As shown, the tea color sorting winnowing machine of the present invention includes a color sorting structure, and the tender tea flow mixed with impurities enters from the upper hopper 1 and falls to the first material wheel 2. The first material wheel 2 has two functions, One is that the first material wheel has equidistant spacer teeth. After the tea leaves enter the equidistant spacer teeth, they are evenly sent to the conveyor belt. Or further sorting to provide a reasonable flow of tea leaves; the second is that the first material wheel 2 can throw the tender tea leaves to the top of the first conveyor belt 3 along the tangential direction of the outer surface of the wheel, and the tender tea leaves are mixed therein due to their own gravity. Due to the buoyancy of the air, the light and flake impurities fall slowly and float farther, so that when the light and flake ...

Abstract

The invention discloses a color s sorting winnower for tea leaves before entering a fermentation process. The color s sorting winnower comprises a color sorting structure, a primary winnowing structure and a secondary winnowing structure which are connected in sequence, wherein the primary winnowing structure and the secondary winnowing structure is in air return connection with a dust collecting cyclone which is connected with an air feeder, and the air feeder is in air supply connection with the color sorting structure, the primary winnowing structure and the secondary winnowing structure.

Description

technical field [0001] The invention relates to a tea sorting machine, which belongs to the field of tea sorting and separation. Background technique [0002] Black tea is a fully fermented tea and one of the most influential teas among the six major teas in China. China is the first country in the world to produce and drink black tea. The existing black tea production process carries out the pretreatment of withering, rolling, fermenting and red pot on the picked tea leaves, but because there are many kinds of tea leaves and the processing techniques have their own characteristics, higher requirements are put forward for the sorting of tea. Technologists hope that the sorting equipment of tealeaves can be applicable to various different kinds of teas. The winnowing function is to use the difference in weight, volume, shape and size of the windshield surface between tender tea leaves and non-tea inclusions such as light impurities, sand and stones, and separate light yellow...
