Basic Principle of Extruding Processing

The principal system is the "screw extruder" for extruding processing, unmarried screw kind and dual screw kind, and additionally devided into dry kind extruder and moist kind extruder or additionally referred to as steam kind extruder.

When we feed fabric into the extruder, the screw and the shaft pushes the fabric to shape an axial flow. At the equal time, because of the mechanical friction among the spiral and the fabric, among the fabric and the sleeves, among the fabric itself, the fabric is strongly squeezed, stirred and sheared, and the fabric can be in addition subtle and homogenized. As the stress progressively increases, the temperature rises correspondingly. Under the situations of excessive temperature, excessive stress and excessive shear, the bodily houses of the fabric changes, from powder to paste, starch gelatinization, protein denaturation, partial of fiber degradation, pathogenic micro organism are killed, fitness signs are improved, and poisonous additives are inactivated. When the paste fabric is ejected from the die mildew hole, below the sturdy stress difference, the fabric is puffed, dehydrated and cooled to pellets, the extruded made of the pellets shape is loose, porous, crisp, and it has appropriate palatability and flavor.


Extruder has appropriate overall performance to supply floating fish feed and puppy food.

Yearmega Company have unique forms of feed extruders with unique capacities, 30kg/h to 5000kg/h on your choice.
