Working principle of Corn puffing automatic production equipment

The unequally spaced non-standard screw system of the extruder is used for extrusion and propulsion. The gas in the material is discharged and quickly filled with the material. The material is subjected to shear force and refluxes, which increases the pressure in the machine chamber. At the same time, the friction between the screw and the machine chamber makes the material fully mixed, extruded, heated, glued, and gelatinized. The mechanical energy is converted into thermal energy, making the material a gelled state with flow properties. When the material is extruded to the outlet, the pressure changes from high pressure to normal pressure in an instant, and the temperature changes from high temperature to normal temperature in an instant. The water evaporates quickly from the tissue structure, forming countless microporous structures inside, and then it is cut and cooled by the cutting device to expand and form.
