The main components of the puffing machine

Screw: It is the main component of the extruder, and the parameters representing the screw structure include diameter, pitch, root diameter, helix angle, and blade cross-sectional structure. The aspect ratio of the extrusion component and the gap between the screw and the inner wall of the expansion chamber also have a significant impact on the performance of the expansion machine.

Discharge mold: It is the stage where the product passes through the puffing machine and has a significant impact on the shape, texture, density, appearance, characteristics, and production capacity of the puffing machine. The bearing housing mainly consists of the bearing housing, main shaft, bearings, shaft sleeves, left and right end caps, sealing rings, and round nuts. The oil filtration and cooling system mainly consists of an oil pump, a cooler, an oil filter, valves, connecting fittings, etc.
