Snack Food Production Line with Twin Screw Extruder

Snack Food Production Line Product Introduction 

The automatic snack food production line is a complete solution for producing puffed snacks, cereal products and extruded food such as corn puffs, cereal flakes and snack pellets. It integrates raw material mixing, twin screw extrusion, shaping, cutting, drying, flavoring and cooling into one continuous automated process.

The twin screw extruder is the core system of the line, where raw materials are processed under high temperature, pressure and shear force, transforming them into expanded products with light texture and uniform structure.

This production line supports various raw materials such as corn flour, rice flour and wheat flour, and can produce different shapes and textures by changing molds. It is widely used in snack food factories, cereal production plants and food processing industries requiring efficient and scalable production solutions.

Production Process Description：

1. Mixing (Mixer)
Raw materials such as corn flour, rice flour and additives are mixed evenly to ensure uniform composition before processing.

2. Extrusion (Extruder)
The mixed materials are fed into the twin screw extruder, where they are cooked under high temperature and pressure to form expanded puffed products.

3. Core Filling (Core Filling Machine)
For filled snack products, materials such as chocolate or cream are injected into the core during extrusion to create filled snacks.

4. Cutting (Cutting System)
The extruded products are cut into desired shapes and sizes using a rotating cutting system.

5. Drying (Oven)
Products are dried in a continuous oven to reduce moisture content and improve shelf life and texture.

6. Shaping (Roller)
Products are shaped or flattened through roller system to achieve specific forms such as flakes or sheets.

7. Flavoring (Oil Sprayer)
Oil and seasoning are sprayed evenly on the product surface to enhance flavor and appearance.

8. Packaging (Packing System)
Finished products are automatically packed into bags or containers, ready for storage or distribution.
