Double screw food extruder

Product Introduction:

Extruder twin screw can be divided into meshing type and non-meshing type according to the relative position, meshing type can be divided into partial meshing type and full meshing type; According to the rotation direction, it can be divided into two types: the same rotation and the opposite rotation, and the opposite rotation can be divided into the inward and outward rotation. The properties of the pressure zone of the co-rotating twin screw are different. The material is rotated by the screw in the inner cavity of the sleeve, resulting in high pressure zone and low pressure zone. The material will flow from the high pressure area to the low pressure area in two directions: first, the wear of the square screw will be reduced with the rotation of the screw, and the material will reach maturation under the action of high temperature and high pressure after transportation, shearing, mixing and heating of the barrel shell. Finally, it will be extruded out of the barrel. Reverse rotating twin screw extruder generally adopts two screws with the same size but opposite thread direction. The difference between inward rotation and outward rotation is that the position of the pressure zone is different. The pressure generated by inward rotation of the twin screw is high and low. When the material passes through the twin screw, it will produce extremely high pressure at the entrance, causing difficulties in feeding. The pressure generated by the outward rotation of the twin screw is upper, lower and higher, which is conducive to feeding. However, compared with the same rotation, the C-shaped material flow formed by the material in the screw can not move from one screw to another, the mixing degree of the material is significantly reduced, and its self-cleaning ability is not as effective and stable as the same rotation twin screw.

The double screw of the extruder developed and designed by our company has the advantages of strong adaptability, sliding transportation, uniform mixing and self-cleaning.

Scope of Application:

High value-added aquaculture and pet feed production, such as eel, turtle and juvenile feed production; Special aquatic feed such as particulate aquatic feed (0.8 ~ 1.5mm in diameter), high-fat aquatic feed and feed with small production volume but frequently changing formula; Puffing snack food and other puffing machine.
