Puff Extruder Machine

The friction between the stack and the chamber makes the materials fully mixed, squeezed, heated, glued, and gelatinized to produce organizational changes, and the original structure is destroyed. At the same time, the mechanical energy is converted into heat energy through the friction of the material in the chamber.The cornmeal is mixed with water and extruded, or pushed, through a machine to form the basic shape. Pressure and heat causes the water to turn to steam, which makes the snack puff up. Then, a rotating knife cuts it into bite-sized pieces.
