Twin screw (rice corn puff) extruder

A twin screw extruder is a machine consisting of two intermeshing, co-rotating screws mounted on splined shafts in a closed barrel. The screws are tight and self-wiping, which eliminates stagnant zones over the entire length of the process section. This results in high efficiency and perfect self-cleaning.Twin screw extruders are principally used for specialized applications such as devolatilization, pumping thermally sensitive materials, ingredient mixing (compounding), and reaction chambers for mixing and transport of viscous materials.
