ABSTRACT:
An evaporative cooler for pouches containing a liquid or semi-liquid material such as tomato paste. The cooler includes a housing, a plurality of generally horizontal endless conveyor assemblies arranged one above the other within the housing in vertically spaced relation and each including an endless conveyor member trained over feed and discharge pulleys at the feed and discharge ends of the conveyor assembly. The upper runs of the conveyor assemblies are driven in successively opposite longitudinal directions within the housing so that a pouch may be deposited on the feed end of the uppermost conveyor assembly, move in one longitudinal direction along the upper run of the uppermost conveyor assembly to the discharge end of the uppermost conveyor assembly for discharge onto the feed end of a lower conveyor assembly, thereafter move in an opposite longitudinal direction along the upper run of the next lower conveyor assembly to the discharge end of the lower conveyor assembly for discharge onto the feed end of a yet lower conveyor assembly and proceed in this manner progressively along all of the conveyor assemblies until discharged from the discharge end of the lowermost conveyor assembly.
