As a new type of food processing technology, puffing technology began in 1910. It was applied in pet food in the United States in the 1950s. The United States first used the extrusion principle to produce pet food, that is, using the extruder. The screw and the screw sleeve are heated and pressurized by pressing the raw material, and the high-temperature and high-pressure food is extruded into the mold ikwol, mo proses blong mekem volium i kam bigwan kwiktaem i kamtru tru long dekompresen blong wantaem nomo.

The difference between the wet puffing method and the dry puffing method is that the raw material is prepared in advance before entering the puffing, and the temperature is raised by steam or water to be pre-cooked. The so-called quenching and tempering refers to the hot and humid action of the pet food raw materials by steam, so that the starch in the raw material is pre-gelatinized, the protein is denatured, and the raw material is i mekim isi, na long dispela rot em i mekim gutpela moa long 'puffing granullation effect' na mekim gutpela kwaliti bilong kaikai bilong dok.
