ABSTRACT:
In a method of treating lumpy and granular materials with gaseous media, the materials to be treated are introduced into open containers having at least two adjacent chambers communicating or connected with each other in their bottom regions. The materials to be treated lie on and contact the bottom and walls of the chamber as a packed bed where the at least two chambers communicate. A plurality of the open containers are arranged one behind the other so as to form a closed circuit or chain and are closeable by stationary lids or hoods arranged in the conveying direction. Each hood has a supply conduit for one container chamber and a drain conduit for the other container chamber. The container chain is moved in phases below the lids or hoods, the lids or hoods closing the containers during each standing phase while the treatment gas is transmitted through the container chambers.
