Corn Puff Extruder Machine

By using the non-uniform non-standard spiral system of the puffing machine for extrusion and propulsion, the gas in the material is discharged and quickly filled by the material. The material is subjected to shear force and generates reflux, increasing the pressure inside the machine chamber. With the friction between the stack and the machine chamber, the material is fully mixed, squeezed, heated, glued, and gelatinized, resulting in tissue changes. The original structure is destroyed, and mechanical energy is converted into heat energy through the friction of the material inside the chamber, making the material into a gelatinous state with flow properties.

When the material is extruded to the outlet, the pressure instantly changes from high pressure to normal pressure, and from high temperature to room temperature, causing water to quickly evaporate from the tissue structure, forming countless micro porous structures inside. Then, it is cut by a cutting device. Cutting and cooling is equivalent to puffing and forming.
