VORTEX EVAPORATIVE DRYING CAMERA WITH INERT CROWN Russian patent published in 2018 - IPC F26B17/10 F26B3/12 F26B3/88 B05B1/34 

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. Vortex evaporative-drying chamber with an inert packing contains an evaporating and drying chamber in the common housing with gas-supplying and outflowing pipelines, filter-heat exchanger, made in the form of a nozzle from the fluidized bed of inert bodies, above which is a sprinkler with injectors. Each of the nozzles comprises a hollow cylindrical body, in the upper part of which an external thread is made for connection to the connection of a distribution pipeline for supplying liquid. In the lower part of the case an outer thread is made for connection to vortex flow splitter. Body has an internal cylindrical chamber for supplying liquid, and in a cylindrical chamber, coaxial to it, the hollow conical swirl is formed with a clearance with respect to the inner lateral surface of the chamber, made in the form of a conical surface with a screw through thread, the vertex of the conical surface of the hollow conical swirl is fixed to the end surface of the rod. Vortex flow diffuser is fixed to the housing by a clip having an internal thread and made in the form of a ring, to which two diametrically located vertical plates are attached, connected in the lower part by a horizontally arranged rod, in the middle of which there is a second swirler made in the form of a disk with screw blades.

EFFECT: increased drying performance.
