The material enters the dog food production machine, and the screw pushes the material to form an axial movement. Due to the mechanical friction between the screw and the material, the material and the barrel, and the inside of the material, the material is strongly squeezed, stirred, and sheared, and the material is further refined and homogenized. With the gradual increase of pressure, the temperature rises accordingly. Under the conditions of high temperature, high pressure and high shear, the physical properties of the material change.

When the paste material is ejected from the die hole, under the action of a strong pressure difference, the material is puffed, dehydrated, and cooled. The structure of the puffed product is loose, porous, and crisp, with good palatability and flavor.
