METHOD AND APPARATUS FOR SEPARATING PRODUCTS BY USING A STREAM OF A CARRIER FLUID

摘要

A method and an apparatus for separating, by using a stream of a carrier fluid, products having a different ratio of mass to surface of impact with the carrier fluid. The method comprises the steps of feeding the products to be separated into a tunnel (2) which runs substantially horizontally and has an inlet (3) for the products which is located in an upper region of the tunnel; striking the products with a main stream of carrier fluid which is directed substantially horizontally and with speeds which decrease from the top of the tunnel (2) downwards in order to convey the products and make them fall in a differentiated manner according to their ratio of mass to surface of impact with the carrier fluid, into receptacles (4) which are provided in the bottom of the tunnel (2) and are mutually spaced in a direction which is parallel to the direction of the main stream inside the tunnel (2).
