Abstract
The present invention pertains to a grate plate utilized in a cooling apparatus. Substantially the entire surface area of the exposed surface is defined by alternating rows of a plurality of (1) substantially rectangular hollow air distribution plenums that travel substantially the entire length of the exposed area in a direction parallel to the movement of solid material through the cooling apparatus. The air distribution plenums have two side walls and a top surface with which the solid material transported to the cooling apparatus comes into contact, and (2) a plurality of pockets that also travel substantially the entire length of the exposed area in a direction parallel to the movement of solid material through the cooling apparatus. The said side walls of the air distribution plenums each have a plurality of air outlets or portals located thereon through which cooling air passes from the hollow interior of the air distribution plenum into a pocket located adjacent thereto. Preferably, the longitudinal edges of adjoining grate plates in the cooling apparatus are fitted to abut with one another and to thereby form, along the point of juncture of the two grate plates, another air distribution plenum.
