Product Introduction for Grain Snack Extruder

The grain snack extruder is a food processing machine designed for puffed cereal snack production with a capacity range of 50–150 kg per hour. Constructed with durable metal components and a compact structure, it provides reliable performance for continuous food processing operations.

This machine processes grains such as corn, rice, wheat, oats, and barley through extrusion cooking technology. It combines heating, pressurizing, and shaping in one system to produce expanded snack products with consistent texture and structure.

The equipment is widely used in snack food manufacturing plants, small food processing facilities, and cereal snack production lines requiring efficient and stable puffed food processing.

Working principle:

Raw grains are fed into the hopper and transported by a rotating screw inside the extrusion barrel. As the material moves forward, friction and pressure increase the temperature and cook the grains. When the cooked material exits through the die opening, the sudden pressure drop causes rapid expansion, forming puffed snacks. A cutting mechanism then shapes the extruded material into uniform snack pieces, allowing continuous production.

Main features:

  • Screw extrusion technology enables continuous puffing and cooking of cereal grains during snack production.
  • Multiple die molds support production of various snack shapes including sticks, rings, balls, and stars.
  • Integrated heating structure ensures stable temperature and efficient grain puffing during operation.
  • Durable mechanical structure improves stability and long-term reliability in continuous production.
  • Energy-efficient extrusion process reduces power consumption compared with traditional puffing methods.
  • Simple control system allows operators to manage production with minimal training.

Application scenarios:

  • Cereal puff snack production plants
  • Rice and wheat puffed snack processing
  • Small snack food factories and workshops
  • Breakfast cereal puffing production
  • Grain-based snack product development
  • Commercial puffed food processing facilities
