1Ton Pet Food Steam Extruder Exported To Italy


The expansion machine has a pair of screw rod and screw sleeve, with the function of mixing and rubbing.After the raw material enters the expanded chamber, the material is subjected to the action of extrusion friction shear between the screw sleeve and so on. During the period of 3-7s, the temperature and pressure increased sharply, and the tissue structure of the material changed, making starch further gelatinized, protein denaturation, crude fiber destruction, and killing salmonella and other harmful bacteria.From high temperature and high pressure material discharging mouth out, its pressure is suddenly released, the moisture in some flash,then shape up beautiful different shape of pet food or floating fish feed.
