Abstract
An extruder system ( ) for the processing of feed materials is provided including an extruder ( ), adjustable back pressure valve assembly ( ) and a superatmospheric post-extrusion product treatment assembly ( ). The back pressure valve assembly ( ) includes an adjustable valve member ( ) which can be shifted to alter the effective cross-sectional open area of a product passageway ( ), and alternately can be shifted to a product diverting position wherein the product is diverted from downstream processing. The treatment assembly ( ) includes a sealed housing ( ) directly coupled to the assembly ( ) so that product emerging from the assembly ( ) passes into housing ( ) without experiencing atmospheric pressure. The treatment assembly ( ) includes a product-guiding cowling ( ) which is open to the atmosphere, together with a sealed housing ( ) for effecting above atmospheric pressure treatment of extruded product.
