Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vegetable processing, in particular to a self-circulating air separator for dehydrated vegetables. BACKGROUND

[0002] The air separator is also called air separator crusher. The device itself is composed of coarse crushing, fine crushing, air conveying and other devices. Its main principle is to use high-speed impact to achieve the purpose of crushing solid particles. It is a machine for separating light materials and heavy materials by blowing. It can be widely used in air separation of various fruits and vegetables to separate fruit bodies from leaves. The application of the air separator greatly saves the production time of enterprises.

[0003] The existing self-circulating air separator for dehydrated vegetables generally directly sends the material into the air separation bin when in use. The fruit bodies and leaves cannot be fully dispersed, resulting in low separation efficiency. When the vegetables are put onto the surface of the conveyor belt, the vegetables are prone to accumulate. Moreover, the amount of vegetables put at a time cannot be effectively controlled, and too much accumulated vegetables entering the air separator can affect the air separation quality, resulting in incomplete removal of impurities in the vegetables. SUMMARY

Through the axial overlapping arrangement of the three conical rings, the overlapping conical rings can make the airflow form a complex and gradient-changing flow field. Different particle sizes and densities of materials can be more accurately separated when passing through multiple conical rings due to different degrees of airflow action, thereby improving the classification accuracy of the winnowing, and making the impurities in the dehydrated vegetables more completely removed. Each conical ring is equivalent to an independent winnowing unit.
