VZP TYPE SPRAY DRYER WITH INERT CARRIER 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. Spray dryer of the VZP type with counter-swirled flows with an inert carrier comprises a cylindrical housing with at least two tangential nozzles for the heat carrier supply, in which pneumatic nozzles are arranged for the initial product supply to the inert carrier layer, between the surfaces of the housing and the perforated grid located perpendicular to the housing axis above the flue cut, the dried solution is sprayed with injectors onto the inert carrier particles. Latter 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 inert carrier is made in the form of a block inscribed into a circle, consisting of seven interconnected by side edges hexagonal parallelepipeds without upper and lower bases, or inert carrier is made in the form of interconnected helical spirals inscribed into a spherical surface with a center lying on the spirals connection axis, or inert carrier is made in the form, of at least twelve connected in a block 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.
