Combined type circulating airflow separation equipment

Abstract

According to the combined type circulating airflow separation equipment, the vibrating screen on the upper side of the circulating cavity can achieve preliminary screening of materials and clear away large and small impurities, meanwhile, the obliquely-arranged vibrating screen can enable screened materials to fall into the circulating box through gravity, energy can be saved, and the occupied area of the combined type circulating airflow separation equipment can be reduced; the power section provides a certain wind speed for materials to be screened, the rectification section rectifies airflow entering the winnowing section into uniform airflow, the situation that the separation effect is affected due to the fact that the materials interact with one another and a negative pressure area is generated in the winnowing section is avoided, the materials are evenly separated according to different specific gravities of the materials, and therefore the purpose of separation is achieved. The rotary air duct ensures the stability of air flow in the circulating cavity, and meanwhile, dust in the materials can be prevented from being directly discharged, so that environmental pollution is avoided; the device is simple in structure and small in occupied area, meanwhile, materials can be efficiently screened in a high-quality mode, and high applicability and universality are achieved.

Description

technical field [0001] The invention belongs to the technical field of food processing pretreatment, and in particular relates to a composite circulating air flow sorting device. Background technique [0002] With the development of science and technology and economic level, the market of sunflower seeds is gradually expanding. However, the value-added level of sunflower seed processing is low, which has become a bottleneck restricting the development of the nut industry. In the long run, the best way to maintain the healthy development of the nut industry is to carry out industrialized comprehensive deep processing of sunflower seeds in combination with the needs of the market. The deep processing of sunflower seeds is conducive to increasing the added value of its commodities, transforming resource advantages into economic advantages, driving planting through processing, promoting development through processing, and bringing tangible and considerable economic benefits to f...

AI Technical Summary

Problems solved by technology

[0003] However, the existing sunflower seed cleaning device adopts the production line method, each device is bulky, and the workshop space requirements are relatively high. Each device needs to be connected by a lifting device, and the cleaning cost is high, thus limiting the increase in sunflower seed production.
