Abstract:
A device for treating particulate product havinga process chamber for receiving and treating a particulate product, said process chamber having a circular bottom being constructed from baffle plates overlapping each other in a manner that slots are formed between said overlapping baffle plates through which slots process air can be introduced into said process chamber with a substantially horizontal component of motion, and means for creating two substantially horizontal flows of incoming process air opposing one another and for creating a breaking-up zone along a diameter of said circular bottom, said means comprising an arrangement of said overlapping baffle plates in that a first horizontal flow is created directed towards said breaking-up zone along said diameter and a second horizontal flow is created directed towards said breaking-up zone along said diameter, said second horizontal flow opposing said first horizontal flow, said two opposing flows meeting at said breaking-up zone along said diameter for forming an upwardly-directed substantially vertical flow.
