VORTEX EVAPORATIVE DRYING CAMERA WITH INERT CROWN Russian patent published in 2018 - IPC F26B17/10 F26B3/12 F26B3/88 

FIELD: technological processes.

SUBSTANCE: invention relates to the technique of solutions, melts and suspensions drying and the preparation of granules of various substances and can be used in microbiological, food, chemical and other industries. This is achieved by the fact that in a vortex evaporative-drying chamber with an inert packing containing the evaporating and drying chambers housed in a common housing and gas supply and discharge pipelines, as well as a filter-heat exchanger, made in the form of a nozzle from the fluidized bed of inert bodies, above which the sprinkler is located. Inertial nozzle is made 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 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.
