Food Extrusion & Processing Machines

Diamond America’s food processing machines produce a full range of pet foods, snack foods and animal feeds, including soft-dry, soft-moist, semi-moist, dry expanded, and co-extruded products in an assortment of sizes, colors, controlled shapes and differing textures. With our single screw food extrusion and die technologies, unique profiles of cooked or cold-formed product can be achieved while achieving controlled, uniform and consistent form, color and properties.

Our Quick Release Die container provides our customers with greater flexibility by offering the capability of easily and quickly changing the extruder dies.

Our equipment is built to current Good Manufacturing Practices as specified by the US Department of Agriculture’ s (USDA) Food Safety and Inspection Service (FSIS) and Food and Drug Administration (FDA) regulations.

Twin Feed Extruders

Twin Feed Extruders
Application: Catalyst, Food, Mastics

Diamond America’s Twin Feed Extruders feature our counter-rotating feed screw design. It provides our customers with the ability to process the most challenging materials while maintaining a positive feed to the extrusion screw. Our completely original design changes the geometry of the screws, barrel liners and feeders used in the extrusion process. As a result, we are able to reduce unwanted friction and eliminate stagnation while operating at peak energy efficiency. 

Built to handle the hard stuff — Petrochemical Catalysts, DeNox Catalysts, Carbon, Rubber (EPDM and Recyclable), Silicone, Clay, and Ceramics — as well as Food Manufacturing (Confectionary, Pet Food, Pasta).

Twin Feed Extruders are available in 2”, 4” or 6” base models, and can be customized to include various die assemblies (profile or pellet processing), temperature control options, and rotary or guillotine cutters.

With proven results in several markets, from catalyst, mastics and ceramics to food, plastics and consumer products, Diamond America manufactures extrusion equipment designed to work and built to last.

Not every application, processing condition and end product is created the same. Our first step in the development a customer’s extruder is thorough research. This includes testing your materials in our lab to determine the ideal extrusion process for producing the high quality structured products our customers demand.
