Food extrusion machinery primarily includes single-screw, twin-screw, and triple-screw extruders, suitable for different food processing needs:

Screw Types

1. Single-Screw Extruders‌

These have lower outputs (100-300 kg/h) and excel at producing non-expanded foods (such as 3D snacks and artificial rice). Raw materials are primarily corn flour and wheat flour.

They have a simple structure but lower production efficiency, making them suitable for small-scale production or for producing foods with specific shapes.
‌2. Twin-Screw Extruders‌

They have higher outputs (up to 600 kg/h) and are widely used in applications requiring high output, such as puffed foods and pet food.

They have self-cleaning features, are suitable for continuous production, and have low energy consumption.

Applications

Expanded foods‌: These foods, such as potato chips and popcorn, achieve a crispy texture through high temperature and high pressure.
‌Pet Food‌: These foods are used in the production of dog chews and cat litter, where both output and shape control are crucial.
‌Material Selection‌: Food-grade stainless steel ensures hygiene and safety, suitable for applications involving direct food contact.
