What is puffing in the processing of dog food?
Puffing is a kind of food processing method. It is to put the processed food into an airtight container, then suddenly reduce the pressure after heating and pressurizing, and the water in the food is vaporized and expanded, which makes the dog food appear many small holes, become crisp and become puffed dog food. Dog food extruder basic principle is to use the screw and screw sleeve in the dog food expander to heat and pressurize the raw materials by extruding them, and to extrude the high-temperature and high-pressure food out of the die hole, so as to realize rapid volume expansion due to sudden decompression.

Puffing process is also a process of forming raw materials for dog food.
In the dog food process of forming, water is added in the form of steam to
gelatinize the starch of dog food raw material and raise the temperature
to 100-180℃. Because the pressure before extrusion is very high,
the pressure is released at the moment of extrusion, and the water
rushes out of the particles at the moment, so that the dog food expands rapidly and foams, and the water evaporates. Therefore, the dog food
manufactured by extrusion process is generally available. Easy to digest and absorb high nutritional value. dog dry food machine equipment for dog food
