FIELD: technological processes.SUBSTANCE: invention relates to the technique of drying solutions, melts and suspensions and the preparation of granules of various substances and can be used in microbiological, food, chemical and other industries. Vortex evaporating and drying chamber with an inert packing contains evaporating and drying chambers in a common housing with gas-supply and discharge pipelines, as well as a filter heat exchanger, made in the form of a nozzle from a fluidized bed of an inert nozzle, above which there is an irrigator with nozzles. Each of the nozzles contains a hollow body consisting of a cylindrical part, a conical transitional part and a cylindrical part with a large size of diametrical section. Coaxially to the body in its lower part a nozzle is attached, it is formed by a cylindrical surface, which passes into a conical surface. Said nozzle is closed with an end solid partition with a jet in its center. Said body and nozzle form three coaxially interconnected internal cylindrical
