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. When the first cooling chamber is empty, its discharge is closed and the new feed material is directed into the first cooling chamber and feed material to the second cooling chamber is stopped. When the second cooling chamber is empty, the new feed material can be directed into the second cooling chamber and discharge of the new feed material from the first cooling chamber can begin.

A method of cooling feed material in a counter flow cooler, the cooler including at least two cooling chambers, the method comprising: admitting a supply of a first feed material into the cooling chambers; passing cooling air through the cooling chambers; discharging cooled first feed material from the cooling chambers; stopping the admission of the first feed material into a first one of the cooling chambers; continuing to discharge first feed material from the cooling chambers until the first cooling chamber is empty of the first feed material, then stopping the admission of first feed material into a second one of the cooling chambers, admitting a second feed material into the first cooling chamber and preventing the discharge of the second feed material from the first cooling chamber until all the cooling chambers are empty of first feed material; after the second cooling chamber is empty of first feed material, admitting the second feed material into the second cooling chamber.
