Abstract: A counter flow cooler in which feed material is fed into the top inlet of the cooler and dispersed into a plurality of cooling chambers. At the bottom of each cooling chamber is a discharge grid which will discharge feed material uniformly over the area of the cooling chamber. The discharge rate of this discharge grid can be adjusted to the desired throughput of the cooler. Air is drawn through the bottom of the discharge grid and passes up through the feed material in a counter flow manner. That is, while the product is passing down through the cooler, the air is passing up through the feed material, carrying away heat and possibly. A feed controller is used to selectively direct feed material into the plurality of cooling chambers. When a second batch of feed material is to be introduced into the cooler, feed material to the first cooling chamber is stopped and all the feed material is directed into the second cooling chamber.

Abstract: A water cooler and dispenser employs a ceramic crock containing a thermoelectric unit and an upwardly directed chilling probe extending into a chilling tank. The chilling probe is in heat-conducting relation to a heat sink, underneath which is a circulating fan. A circulating base is made up of a series of support fins arranged in a radial fashion in the bottom of the crock having a specialized arrangement of inlet and outlet ports. The air is circulated upwardly across the heat sink then circulated downwardly and expelled from the crock. In a conventional manner, water is drawn from the lower end of the chilling tank through a spigot extending to the exterior of the crock.
