DEVICE FOR DRYING DISPERSE HIGH-HUMIDITY MATERIALS Russian patent published in 2016 - IPC F26B17/10 F26B17/26 

FIELD: technological processes.

SUBSTANCE: invention relates to drying, heat treatment of disperse high-humidity materials and can be used in food, chemical and other industries. Apparatus includes tight chambers connected to each other: chamber of vibrofluidised bed and chamber of fluidised bed, and atmospheric pressure and low pressure steam superheaters. Atmospheric pressure and low pressure steam superheaters are installed on outer side of chambers of vibrofluidised bed and fluidised bed, respectively, and are connected thereto by separating shutters, chamber of vibrofluidised bed is additionally equipped with a box for removal of waste atmospheric pressure superheated steam with built-in control shutter, wherein box is connected to low pressure steam superheater, and grid of vibrofluidised bed chamber is installed with possibility of adjusting inclination angle; inside chambers at full width there are spring-loaded inclined inserts, fixed pivotally with possibility of rotation, turning angle of which exceeds angle of natural slope of material, wherein lower edges of inclined inserts are arranged with identical gaps over grids for unobstructed movement of material over surface of said grids.

EFFECT: invention must improve quality of dried material and reduce specific energy consumption of drying process.
