SPRAY DRYER WITH INERT NOZZLE BETWEEN VIBRATORY PLATES Russian patent published in 2018 - IPC F26B17/10 F26B3/12 F26B3/88 F26B3/92 

FIELD: technological processes.

SUBSTANCE: invention relates to the disperse materials drying technique in fluidized bed and can be used in dye-making and dye-using industries, in food, pharmaceutical, microbiological, chemical and other industries. Spray drier with an inert packing between the vibrating plates contains a housing with a gas distribution grid, vibrating plates, an inert nozzle, an injector, a vibrating mechanism. Inert nozzle is made in the form of a cylindrical ring, on the lateral, inner and outer surfaces of which a screw thread is made in opposite directions, or in the form of a ball on the surface of which blind holes of hemispherical shape are made, or in the form of a ring on the outer surface of which a screw surface is made in the manner of a plate auger, or in the form of at least a three-bladed propeller, or in the form of a cylindrical ring, on the lateral inner surface of which are fixed partitions in the form of holes perpendicular to the axis of the ring of washers whose axes are asymmetric to the axis of the ring, 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 an inert nozzle is made in the form of at least twelve connected three-bladed propellers, the projection of which on the plane of the drawing is inscribed in a circle with a center coinciding with the center of one of them.

EFFECT: increased drying performance.
