FIELD: the invention refers to the field of water extraction technologies out of drying materials and may be used in different branches of industry such as wood-manufacturing, chemical, biological, pharmaceutical, textile and also in agriculture. ^ SUBSTANCE: in the mode of drying materials with the aid of thermal, acoustic and convective impacting on drying material is heated air is supplied into the chamber of the sound source and acoustic field and convective flow directed in a common acoustic duct are simultaneously made in it. The flow is given into each drying chamber separately or into all simultaneously before receiving given moisture of material. An average convective speed of the air for all drying chambers for example for gas-dynamic generator is defined according to a calculating formula. The arrangement has several drying chambers located in the flatness of the chamber of sound source in radial direction relatively to its vertical axle and forming with it a common acoustic duct. The chambers are prolongation of common acoustic duct and are provided at the entrance with dampers for possibility of alternate or simultaneous impacting of air flow on material, and at the exit- openings. ^ EFFECT: the invention must provide increasing effectiveness of using acoustic energy. ^ 3 cl, 2 dwg |
