SUBSTANCE: drying plant includes housing with loading and unloading bins, gas distributing unit divided into inclined sections by partitions; each section has form of funnel in cross section; one side of this funnel is formed by gas distributing perforated curvilinear members directed towards unloading and other side of this funnel is made in form of sectional member consisting of upper and lower plates with nozzle located between them; upper plate is provided with member for mating with partition; has directing tube is provided between lower plate of sectional member and distributing perforated curvilinear member; this tube is so positioned that clear opening and flow of heat-transfer agent nay be changed; partitions have varying height depending on kind of product taking into account reduction of moisture content; axes of perforations of gas distributing perforated curvilinear member are inclined towards each other in way of partition; diameter of holes increases towards partition. EFFECT: reduced power requirements; reduced drying time; reduced local hydrodynamic resistance of drier. 2 cl, 3 dwg
