High-Efficiency Automatic Puff Corn Production Line for Snacks

The line produces twin-screw extruded puffed snacks such as corn puffs, rice puffs, cereal balls, sticks, rings, cartoon shapes, and other formed puffed snack products. With different moulds and cutting settings, a wide variety of shapes and sizes can be made.

Standard configurations are commonly available from about 60-80 kg/h up to 200-300 kg/h and above. The exact capacity depends on the extruder model, raw material, product shape, and the downstream sections selected.

Twin-screw extrusion uses two intermeshing rotating screws inside a heated barrel to mix, cook, and plasticize the raw material under high temperature and pressure. When the material exits the die, the sudden pressure drop expands it into a porous, puffed texture.

A twin-screw extruder offers better mixing, self-cleaning screws, more stable processing, a wider raw-material tolerance, higher output consistency, and easier adjustment of barrel sections and screw configuration than a single-screw machine.

The typical flow includes raw-material mixing, screw conveying, feeding, twin-screw extrusion, cutting at the die, optional drying or baking or frying, oil spraying, seasoning, cooling, sifting, and packing.
