We will introduce you to the feed pellet production line, the role of the puffing machine, first of all, we understand the concept of puffing in the dog food processing, puffing is a food processing method, is to be processed food into a closed container, heated and pressurized after a sudden decompression of the water in the food vaporization and expansion of the food, so that the food appeared in a number of small holes, become crunchy, and become puffed food. The basic principle is to let the raw materials in the heating, pressurization suddenly decompression and make it expand.
Expansion technology as a new type of food processing technology, that is, the use of puffing machine within the screw and screw sleeve through the extrusion of raw materials to make it warm, pressurized, and high temperature and high pressure of the food extrusion mold empty, due to the sudden decompression to achieve the volume of the rapid expansion of the process. Improve the palatability of pet food; change or improve the nutritional value of pet food.
