Abstract
An improved extrusion conditioning apparatus (10) includes an extrusion and cooker (12) and a closed loop pneumatic conditioning system (14) operatively coupled with the cooker (12). The closed loop system (14) includes a hood (16) disposed about the extruder outlet, together with first and second conduits (20, 22) operatively coupled with the hood and a cyclone separator (18); and a fan (24) and a heater (26) are operatively interposed within the conduit (22). In use, extrudate from extruder (12) is picked up by positive pressure air currents created by the fan (24), and such product is then conveyed to the separator (18) for separation thereof. The separated air then returns to the hood (16) via the conduit (22), and is heated during such return passage. Use of a largely positive pressure, heated air conveying system (14) minimizes product contamination by airborne microorganisms, while at least partially sterilizing the product prior to drying thereof.
