Quadro barrels are designed for broad production capabilities with maximum efficiency and minimal metal-to-metal wear. each extruder model can be equipped with multiple barrel length packages, each designed for the production of specific product types. the back of the inlet heads incorporate two mechanical seals which prevent material leakage between the rear of the inlet head and drive shaft.

Adequate spacing is provided between the inlet head and bearing housing to further prevent the chance of material reaching the bearing housing seals. Segmented screws and shearlocks are positioned on the extruder drive shaft and can be configured to attain desired characteristics for a wide variety of extruded products. Segmented, jacketed heads with replaceable wear liners allow for easy injection of either water or steam into the individual barrel segments to control extrusion temperatures. High-pressure steam is injected into the product zone to enhance cooking characteristics and increase the rate of production.

All screws and liners are constructed of high quality, wear-resistant stainless steel alloys. Upon completion of manufacturing, screws are polished, heat treated to required hardness specifications, and then parallel ground to ensure proper fit between barrel components.
