Summary: Separate particles based on size.

Screens in food processing machinery are used to separate food materials based on their size. This process, known as screening or sieving, is a fundamental step in many food production lines.

Function: Screens perform several important tasks:

Grading: Sorting food particles into different sizes (e.g., separating grains by size).

Separating: Removing unwanted particles or debris from food (e.g., removing seeds from pulp).

Classifying: Grouping food materials based on specific size ranges.

Mechanism: Screens use a mesh or perforated surface with openings of a specific size. Food materials are passed over or through the screen, and particles smaller than the openings pass through, while larger particles are retained.

Types: Screens come in various forms:

Vibrating screens: Use vibration to move the food and facilitate separation.

Rotary screens: Use a rotating drum or cylinder with screen openings.

Sieves: Simple hand-held screens for smaller-scale operations.

Applications: Screens are used for a wide range of food products, including:

    * Grains and cereals

    * Fruits and vegetables

    * Spices

    * Nuts and seeds
