What Does The Puffing Process in Feed Pellet Production Line Mean?

                   Using the screw and screw sleeve in the extruder to heat up and pressurize the raw materials by extruding them, and extruding the high-temperature and high-pressure foodstuffs out of the die holes, and realizing the rapid expansion of volume due to the sudden decompression of the process. Expansion process is also a process of dog food raw material molding, molding process in the form of steam will be added to the water, so that the raw material in the dog food starch paste, heating to 100 ℃ ~ 180 ℃.

                   Because the pressure before extrusion is very high, the pressure is released instantly when extruding, which makes the dog food expand and foam rapidly, and the water evaporates, so the dog food after the puffing manufacturing process generally has a high nutritional value that is easy to digest and good for absorption. Improve the palatability of dog food, dry dog food, after puffing becomes crispy, the pet dog in the process of biting off and swallowing, there is a better taste and clean the oral cavity teeth.
