Cam vibration-based screening equipment for processing black tea

Abstract

Cam vibration-based screen equipment for processing black tea comprises a housing. A first-grade screen mesh and a second-trade screen mesh are disposed in the housing; the first and second-grade screen meshes incline toward a bottom left direction; the first-grade screen mesh is arranged over the second-grade screen mesh; the diameter of a mesh of the first-grade mesh is greater than the diameterof a mesh of the second-grade mesh; a lower end of the first-grade screen mesh is correspondingly provided with a first-grade outlet and a lower end of the second-grade screen mesh is correspondinglyprovided with a second-grade outlet; the internal top of the housing communicates with a dust collector arranged outside the housing via an air pipe; a pedestal is arranged under the housing; a firstgroove is formed in the pedestal; a vibrating device is disposed in the first groove; the vibrating device has a rubber pad; the rubber pad is fixedly connected to the bottom of the housing; and therubber pad is also placed in the first groove. The beneficial effects are that dust in the housing can be sucked out by the dust collector, so body health of an operator can be effectively protected;and the housing vibrates due to the vibrating device, so black tea can be effectively screened.

Description

technical field [0001] The invention relates to the mechanical field of black tea processing equipment, in particular to screening equipment for black tea processing based on cam vibration. Background technique [0002] Black tea originated in China. The earliest black tea is called Lapsang Souchong. It was created by the ancestors of the Jiang family in Tongmu Village, Xingcun Town, Wuyishan City, Fujian Province in the middle and late Ming Dynasty (about 1568). The Jiang family in Tongmu Village, Wuyishan City is a tea family that produces Lapsang Souchong black tea, with a history of more than 400 years. [0003] Black tea is a kind of fully fermented tea, which is refined from the buds and leaves of tea trees through typical processes such as withering, rolling (cutting), fermentation, and drying. Because of its dry tea color and the brewed tea soup is mainly red, it is named black tea. There are many types of black tea, and the production area is wide. Qimen black tea...

Problems solved by technology

In the current technology, when black tea is screened, it is manually screened through a mesh screen. This method has low work efficiency and requires a large labor cost; another method is to use a motor to drive the drum to rotate, but this method is not easy to add black tea. Moreover, the movement of the drum during rotation is relatively large, which may easily cause the dried black tea to be broken, thereby affecting the selling price; and there will be a lot of dust in the screening process of black tea, which will bring great health problems to the operators.
