Extruders

The Marlen Model 750 twin-piston continuous extruder was designed specifically for continuous extrusion of shear sensitive materials such as corn masa for corn chips. With 6" pumping cylinders, 6" outlets, commonly connected to an 8" outlet, the product is subjected to very little shear.

In operation, the hot milled corn or other material is milled directly into the extruder hopper or is conveyed into the hopper. Once the material is in the extruder hopper, the extrusion operation is continuous and automatic. A built-in metering system provides continuous flow and uniform chip length. This machine is designed to be fitted with an elbow and a corn chip die assembly (both sold separately).

Optional vacuum pistons enhance performance by removing air, thus reducing spattering and creating fewer fines in the cooking oil. The vacuum pistons also assists in loading, which results in fewer machine cycles and longer machine life.
