FLUIDIZED BED SPRAY DRYER WITH THE INERT NOZZLE Russian patent published in 2018 - IPC F26B17/10 F26B3/12 F26B3/88 

FIELD: technological processes.

SUBSTANCE: invention relates to the technology of drying disperse materials in a fluidized bed and can be used in aniline, food, pharmaceutical, microbiological, food, chemical and other industries. Fluidized bed spray dryer with an inert nozzle contains a housing with a gas distribution grid and an acoustic nozzle, vibrating plates, inert nozzle, injector. Vibrating mechanism is made in the form of plates mounted in the dryer housing with the possibility of rotation relative to the axes. Inert nozzle is made in the form of a cylindrical ring, on which side inner surface partitions in the form of washers with holes perpendicular to the axis ring are fixed, which axes are asymmetric to the ring axis, or an inert nozzle is made in the form of a block inscribed in a circle, consisting of seven interconnected side edges of hexagonal parallelepipeds without an upper and a lower base, or an inert nozzle is made in the form of interconnected helical spirals, inscribed in a spherical surface with a center lying on the axis of the connection of the spirals, or the inert nozzle is made in the form of at least twelve connected in a block of three-bladed propellers, which projection onto the drawing plane is inscribed in a circle with a center coinciding with the center of one of them.

EFFECT: increase in drying performance.
