Screening apparatus for green tea processing based on electromagnetic vibration principle

Abstract

A screening apparatus for green tea processing based on the electromagnetic vibration principle comprises a housing and an upper cover; the inner wall of the housing is provided with a slideway, a slide screen is arranged on the slideway, soft iron is arranged at the lower center of the slide screen, the inner bottom of the housing is provided with a first cavity right below the soft iron, an electromagnetic core is arranged in the first cavity, an electromagnetic coil is wound on the electromagnetic core and is electrically connected with a power supply, a plurality of first springs are alsoarranged at the inner bottom of the housing, the slide screen is positioned above the first springs, the upper portion of the housing is provided with an exhaust pipe, and the exhaust pipe is connected with a dust collector positioned outside the housing. The screening apparatus for green tea processing based on the electromagnetic vibration principle has the advantages that the dust collector sucks out dust in the housing to effectively protect body health of an operator; the slide screen is vertically vibrated through the first springs and the electromagnetic coil, and efficient screening ofgreen tea is achieved. The apparatus for green tea processing based on the electromagnetic vibration principle is reasonable in structural design and simple to operate.

Description

technical field [0001] The invention relates to the field of green tea processing equipment machinery, in particular to screening equipment for green tea processing based on the principle of electromagnetic vibration. Background technique [0002] Green tea (Green Tea) is one of the main teas in China. It refers to a drink made from the new leaves or buds of the tea tree without fermentation, and through processes such as greening, shaping, and drying. The color of its finished product and the tea soup after brewing mostly preserve the green style of fresh tea leaves. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and can also reduce the damage of nicotine to smokers. [0003] Green tea is made without fermentation, which retains the natural substances of fresh leaves, and contains more nutrients such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids, and vitamins. These natural nutrients in green tea have special effects on an...

Problems solved by technology

In the current technology, green tea is screened manually 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 green tea. Moreover, the movement of the drum when rotating is large, which may easily cause the dried green tea to be broken, thereby affecting the price; and there will be more dust in the screening process of green tea, which will bring greater health to the operators.
