Category: Food Processing Machinery

Summary: Force food through a die to create shapes.

    Extruders in food processing machinery are versatile machines that force food materials through a shaped opening (die) to create continuous products with a defined form. This process, called extrusion, is used to manufacture a wide variety of food items.

Function: Extruders perform various functions, including:

    Shaping: Creating specific shapes like pasta, cereals, or snack foods.

    Cooking: In some extruders, the process involves cooking the food as it is shaped due to heat and pressure.

    Texturing: Altering the texture of food, such as creating expanded or puffed products.

Mechanism: Extruders use a rotating screw or screws to push the food material through the die. The shape of the die determines the shape of the extruded product.

Types: Extruders come in different types:

    1. Single-screw extruders: Use one screw.

    2. Twin-screw extruders: Use two screws, offering more control and versatility.

Applications: Extruders are used in the production of:

    1. Pasta

    2. Breakfast cereals

    3. Snack foods (e.g., puffed snacks, chips)

    4. Pet food

    5. Textured vegetable protein
