The extrusion and propulsion of the unequally spaced non-standard spiral system of the food puffing machine is used to quickly fill the material while the gas in the material is discharged. The material is subjected to shear force and refluxes, which increases the pressure in the machine chamber. With the friction between the stack and the machine chamber, the material is fully mixed, extruded, heated, glued, and gelatinized to produce organizational changes. The mechanical energy is converted into heat energy through the friction of the material in the chamber, making the material a gelled state with flow properties. When the material is squeezed to the outlet, the pressure changes from high pressure to normal pressure in an instant, the original structure is destroyed, and the temperature changes from high temperature to normal temperature in an instant, forming countless microporous structures inside, causing water to evaporate quickly from the organizational structure, and then passing through the cutting device, cutting and cooling, that is, puffing and forming.

1. If the extruder is shut down normally, it is easy to clean. Just use a wire brush to clean it. The mold core can be cleaned with a small hand drill.
2. If the machine is shut down due to blockage or jamming, you need to remove the head nut while it is hot and take out the screw sleeve inside.
3. If the temperature is too high, you need to wear thick gloves to avoid burns, then use fire or put it on gas to burn the material inside and then clean it up.
