Th production technology for floating feed machinery

DATE：2016/06/24

   Extruded feed technology is mainly used for special aquatic feed, pet food and other animal feed production.In addition to the advantages of general pellet feed , it could improve rate of digestion and absorption and effectively prevent animal digestive tract diseases.
   Extruded Feed not only because the starch gelation gelatinized starch can be applied to the higher fat content of the material, but also because of the high temperature, high pressure curing effect, disinfection, sterilization effect is more obvious, applicability, by extruded feed resources more widely.Because of extrusion processing has so many advantages, more and more feed mill began to use extrude technology.At present , the working principle of extruder which is used by domestic feed mill .is to contain a certain amount of starch (over 20%), after quenching is quenched, so that the material moisture can reach 25% to 27%, the temperature rises to 80 ℃ ~ 100 ℃.
    Extruder including feeding system, transmission system, extrusion system, the material molds and electrical control system
    Quenched and tempered good material into screw extrusion zone, due to the axial compression zone volume becomes smaller, the materials are subjected to gradually increasing pressure, the compression ratio up to 4-10. Screw extrusion material is driven, accompanied by strong shearing and friction, a sharp rise in pressure and temperature, the material under the effect of high temperature, high pressure, which can substantially completely gelatinized starch, protein portion is deformed. When the material is great pressure extrusion die orifice, due to the sudden departure of the body into the air, temperature and pressure plummeted, with the joint effect of pressure, temperature, and feed the rapid expansion of the volume of the material to flash, namely rapid evaporation of moisture , dehydration coagulation, and then through a custom mold the material needed to achieve a variety of shapes and structures, it is made of the extruded pellets.
