Working Principle of Single Screw Snack Food Extruder

During the extrusion and expansion process, the material is placed in a sealed barrel equipped with a screw (spindle). With the forced advancement of the screw, due to the extrusion of the single screw and the barrel wall, the internal shear force of the material and The external thermal energy makes the material at high temperature (temperature can reach 100 ~ 200 °C).

 

Because the material is in a sealed state, high pressure is generated as the sealed volume changes and the temperature rises, which gradually turns the material into a gel state of a thermorheological body and obtains a large amount of energy to change the original physical and chemical Attributes. 

1. Precision: The extrusion system is equipped with advanced multiple sets of temperature control and automatic cooling devices, which are accurate and reliable in temperature control.

2. High degree of automation: feeding, rotary cutting, and main drive all adopt variable frequency speed regulation system, which has a high degree of automation.

3. The unique design of discharge guide, the pressure at each point in the mold is more balanced, the extruded product is more uniform, and the product appearance is more beautiful and consistent.

4. The raw material quenching and tempering system can be configured to mix the raw materials more evenly, so that the product quality is better and the taste is better.

5. This single screw snack extruder equipped with automatic lubrication system to reduce mechanical energy consumption and prolong service life.

6. Comprehensive coverage, can produce different snacks, is a production line solution and a variety of single screw snack food kurkure puffed extruder equipment.
