ABSTRACT:
The pellet mill in a processing system for dehydrated forage crops is disposed in proximal pellet-dispensing relation to a pellet pre-cooler for gentle initial cooling and preliminary firming of hot pellets from the mill prior to their conveyance to the primary cooler, whereby to reduce undesired deterioration of the hot pellets into fines during subsequent bulk conveying and cooling operations. The pre-cooler includes an enclosed conveyor presenting a moving pellet-supporting surface for gently transporting hot pellets from the pellet mill along a predetermined path of travel within a vented housing. A blower in communication with the primary cooler creates a negative pressure airflow sufficient to convey pellets from the pre-cooler to the primary cooler; the blower simultaneously draws ambient air into the housing for initially cooling the hot pellets on the conveyor prior to their transfer to the primary cooler. In preferred forms, the pellet-supporting surface is defined by plate sections having multiple perforations for increased circulation of cooling ambient air within the housing.
