Abstract:
A process for rapidly transferring a product from a gas stream into a carrier gas stream while avoiding an intermixture of the two gas streams which comprises separately introducing the product-containing gas stream and the carrier gas stream at different levels into a separating apparatus, maintaining separation of the two gas streams by insert means forming a slot with the wall of the lower part of the apparatus, and deflecting the product particles entering with said first gas stream to pass through the slot and thereby to meet the carrier gas stream at the lower level, by which stream they are taken along, and finally withdrawing the carrier gas stream with the particles therein at the bottom of the apparatus. An exemplary embodiment of the apparatus by which the process may be carried out is likewise shown.
