Abstract
Apparatus is provided for efficiently cooling a moving bed of gas permeable particles descending downwardly through a converging bin. The apparatus includes a support mechanism and an especially configured gas distributor depending downwardly therefrom within the bin. The distributor includes a plurality of tiered gas units in nested relationship with one another and arranged in progressively smaller sizes from the top of the distributor. Each gas unit contains a predetermined number of peripherally spaced gas outlet ports to provide streams of cooling gas under sufficient pressure at each unit to effectively cool the bed of particles.
