As more and more consumers are now looking for healthier snack alternatives, and interesting flavor combinations, the extruded puffed snacks meet consumers’ current appeal of healthy snack foods. Co-extrusion puffed snacks are just one of the branches of regular puffed snacks. During puffing/expanding, the center filling machine injects sugar/chocolate/jam into the center of snack quickly through the die.

The co-extrusion snack food processing machinery process includes mixing, extrusion-cooking, center filling, shaping, low temperature drying, seasoning, and packing. As the name suggests, the production process of co-extruded puffed snacks has one more process of center-injection molding than the regular ones.

Corn flour and potato flour are heated, cooked, and kneaded in a specially designed extruder cavity, and finally through the change of high pressure or thermal gradient at the outlet, the vapor pressure escapes from the micropores of the grain structure, thereby realizing puffing. Inject the core with  sugar/chocolate/jam/cream at the moment of puffing through the die.  And then the puffs are cut into the required size by the fast rotating cutter (or cut after shaping process). By the time, the plain puffed snack production is done. According to market demand, seasoning drums can be used to sprinkle salt and sugar on the plain puffed snack. Finally, it goes through medium temperature drying and seasoning process. There is no frying in the whole production process.

All food-contact materials are food-grade, such as SUS304, food-grade silicone, food-grade coating, etc.

Different co-extruded puffes snack shapes can be obtained by changing different dies and shaping machine, such as pillows, square bars, stick bars, balls, etc. Remove the center filling machine to produce regular puffed snacks. Efficient, economical and flexible for developing new products.
