Background technique

The air separator is an important part of the threshing and re-baking production line. Its function is to separate the stem and leaf mixture output by the leaf topper into simple leaves and tobacco stems. The traditional air separator adopts the principle of gravity flotation, and uses wind force to separate the qualified leaves after threshing from the stems and leaves of tobacco after threshing. During air separation, the material is separated by using the difference in suspension velocity between materials or different components of the material, that is, the material whose suspension velocity is lower than the airflow velocity rises with the airflow, while the material whose suspension velocity is greater than the airflow velocity falls down. Using gravity flotation air separation has a simple structure and large processing capacity, but there are problems such as large load on the air separator and high energy consumption. It is often necessary to configure 6-level air separation after a dozen to ensure the air separation efficiency of the blades after beating.
