METHOD OF DRYING CAPILLARY-POROUS MATERIALS AND DEVICE TO THIS REALISATION Russian patent published in 2009 - IPC F26B5/02 F26B17/12 

FIELD: heating; drying.

SUBSTANCE: present group of inventions pertains to technology of drying capillary-porous materials, mainly seed corn and oilseeds, and can be used in agriculture and other industries. Method of drying capillary-porous materials employs effect of ultrasonic vibrations, generated by electroacoustic transducers, on stream of capillary-porous materials, moving under the effect of gravitational force. The effect of ultrasonic vibrations on capillary-porous materials is achieved through mechanical contact with emitting surfaces of electroacoustic transducers. Device for drying capillary-porous materials comprises storage bin, on the sidewalls of which are oppositely mounted electroacoustic transducers, electrically connected to power supply, device for loading the capillary-porous materials and device for offloading the finished product. The emitting surfaces of the electroacoustical transducers are inside the storage bin. The distance between the emitting surfaces ranges from one to two maximum dimensions of separate elements of the capillary-porous materials. Linear dimensions of the storage bin in places where the emitting surfaces are located are many times larger than its cross sectional dimensions.

EFFECT: increased output and quality of drying and reduced power inputs.
