Sieving machine
After sorting in plansifters, semolina and middlings fractions are obtained, which are uniform in size but differ in the ratio of husks to kernel. The screening machine is designed for the enrichment and sorting of semolina and middlings, as well as other bulk materials, based on their size and the aerodynamic properties of the particles using sieves and an airflow. It is primarily used in grain mills but can also be employed in other industries for sorting dry, loose, and non-cohesive materials.

Additional information
The technological process of sorting and enriching products in the machine occurs through the interaction of the product's movement across the sieves, caused by the reciprocating motion of the sieve housing, and an upward airflow.
Air enters from the undersieve space, flows upward through two sieve tiers, and exits into the aspiration network. As the product layer is loosened by the air, the densest particles move downward and sift through the sieves, while the least dense and roughest particles move to the top layer of the product and flow toward the discharge.
The lightest husk particles are carried away by the airflow. This process effectively sorts and enriches the product.
