DEVICE FOR SPRAY DRYING AND GRANULATING PULSE-6 TYPE PARTICULATES Russian patent published in 2009 - IPC F26B17/10 F26B3/12 

FIELD: heating, drying.

SUBSTANCE: invention relates to technology of drying particulates and can be used in microbiological, food, chemical and other industries. Device for spray drying and granulating particulates comprises case on the upper part of which there is spraying chamber, with atomiser and collector for supplying the spraying agent, drying chamber with system for cleaning waste air, granulated inert material, placed in gas-distributing array, brought into fluidised state by applying horizontal oscillations on spring-loaded case through vibrator. The case undergoes elastic compensating movements through insertions in the upper and lower parts of the case. Dried product together with exhaust spraying agent is discharged through the opening of the gas-distributing array to the trapping system, consisting of container, acoustic installation, cyclone collector and bag filter. The atomiser is acoustic and has a case inside of which there is generator of acoustic vibrations in the form of nozzle, made on the cover and rod-like gas-edge generator and pipe for feeding in the spraying agent and moist raw material. The case is made in form of cup with base, in which there is cylindrical cavity for feeding in moist raw material through the pipe on the cover, in the upper part of which there is fastener, holding to the nozzle the upper part of the rod of the rod-like gas-edge generator, while the upper part is hinged to the lower part of the rod, which is fixed relative to the tapered hole made on the cover by at least one fixing disk, in the form of at least three elastic blades touching the inner surface of the tapered hole of the cover. Between the holes at the bottom of the case and the outer surface of the nozzle there is conduit through which enters the moist raw material. Between the inner surface of the tapered hole and the outer surface of the lower part of the rod there is ring-shaped channel, through which passes the spraying agent.

EFFECT: increase in efficiency of drying.
