Dust removing device for water-removing machine

Abstract

The invention relates to the technical field of tea processing, and particularly relates to a dust removing device for a water-removing machine. The dust removing device comprises a dust removing cylinder, wherein a feed opening and a discharge opening are formed in the dust removing cylinder; a stirring impeller is arranged in the dust removing cylinder, and is used for stirring tea at the feed opening to the discharge opening; a plurality of electrostatic plates are arranged on the dust removing cylinder, and include electrostatic adsorption faces close to the stirring impeller; a filter isarranged between the electrostatic adsorption faces and the stirring impeller; a plurality of screening devices are arranged under the discharge opening, and comprise push plate cylinders, screening plates, vibration motors and guide plates, and the screening plates are used for carrying fallen tea, tea dust and impurities; the vibration motors are fixed on the screening plates, and are used for driving the screening plates to perform vibration and screening; the push plate cylinders are used for pushing the screened tea, tea dust and impurities onto the guide plates; and the guide plates areused for guiding the tea, tea dust and impurities into a container for holding. The dust removing device can be used for removing impurities after drying, and has a screening function.

Description

【Technical field】 [0001] The invention relates to the technical field of tea processing, in particular to a dedusting device for a degreening machine. 【Background technique】 [0002] China has a tea culture of thousands of years, with a long and profound history. Finishing is one of the primary processes of green tea, yellow tea, black tea, oolong tea, etc. The main purpose is to destroy and passivate the oxidase activity in fresh leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make the tea soft, easy to knead and form, and emit green odor at the same time Taste, promote the formation of good aroma. [0003] Before the finishing process of green tea, yellow tea and dark tea, it is often necessary to carry out inspection and acceptance treatment. The inspection and acceptance treatment is to remove the deteriorated and odorous tea leaves, and remove impurities at the same time. Now...
