Abstract

Method for drying of moisture-containing powder-like products, particularly starches and flours, in a flow tube passed-through by conveying gas, in the interior of which--distributed over the entire length of a central and rotary arranged tube--there are provided helically extending guide members for the production of a helical path of the feeding gas stream and for the distribution of the product stream is characterized by the product stream which is fed into the feeding gas stream prior to its entry into the flow tube is guided via a tube length and thereafter is immediately admitted into the flow tube together with the feeding gas.
