DEVICE FOR DRYING OF SOLUTIONS AND SUSPENSIONS IN FLUIDIZED BED OF INERT BODIES Russian patent published in 2018 - IPC F26B17/10 F26B3/12 F26B3/88 

FIELD: technological processes.

SUBSTANCE: invention relates to the drying of dispersed materials and can be used in microbiological, food, chemical and other industries. Device for drying solutions and suspensions in the fluidized bed of inert bodies comprises a drying chamber with a movable gas distribution grid in its lower part, made in the form of a rotating hollow perforated cylinder, engaged with a gear drum, and grinding bodies are placed in the cavity of the cylinder. Acoustic nozzle contains housing with internal acoustic oscillation generator in form of nozzle and resonator, nozzles for supplying air and liquid. External diffuser is coaxially attached to the nozzle casing, and an inner perforated diffuser is coaxially attached to the fastener of the annular cavity resonator with the resonator rod in such a way that the output sections of the external and internal diffusers lie in one plane perpendicular to the axis of the annular volumetric resonator. Additional flow diffuser, made in the form of a cylindrical shell, is coaxially attached to the external diffuser of the acoustic nozzle, on the end part of which, on the opposite side of the diffuser, a perforated plate is fixed.

EFFECT: increase in drying performance.
