Problems solved by technology

There is a lot of dust in the material screening process, and the grains will be thrown out of the equipment during the raw material screening process, causing waste and loss, and causing great pollution to the natural environment and working environment
At the same time, the vibration screening method has strict requirements on raw materials, such as specific gravity, viscosity and other physical properties, which lead to an increase in the frequency and power of the vibration motor, and an increase in energy consumption.
At the same time, since vibratory screening is based on particle size, the gravel with a particle size similar to that of the raw material cannot be removed.

Abstract

The invention relates to an automatic grain screening machine which is characterized in that the screening machine comprises an induced draft separation device, a screening separation device and a stone removal separation device, the induced draft separation device is used for removing light impurities in grains; the screening separation device is positioned downstream the induced draft separation device and used for screening impurities lager than grain particles and sand particles smaller than the grain particles, and the stone removal separation device is positioned downstream the screening separation device and used for removing abreast stones in the grains. Compared with the prior art, the automatic grain screening machine can completely screen all impurities in the grains, the impurities are cleanly removed, and food sanitation is effectively ensured.

Description

technical field [0001] The invention relates to a grain processing equipment, in particular to an automatic grain screening machine. Background technique [0002] In the field of brewing, the traditional method of grain screening is to use vibrating screening equipment, which relies on a certain frequency of motor vibration to make granular objects pass through the screen, so as to achieve the classification of raw materials. There is a lot of dust in the material screening process, and the grains will be thrown out of the equipment during the raw material screening process, causing waste and loss, and causing great pollution to the natural environment and working environment. At the same time, the vibration screening method has strict requirements on raw materials, such as specific gravity, viscosity and other physical properties, which lead to an increase in the frequency and power of the vibration motor and an increase in energy consumption. At the same time, since vibra...
