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 inert packing contains evaporating and drying chambers located in a common housing, 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 there is a sprinkler with injectors. Each of the nozzles comprises a cylindrical body with a fitting rigidly connected to a housing coaxially disposed at the upper part of the housing and having a cylindrical fluid inlet connected to a diffuser that is axisymmetric to the housing and the fitting, and in the lower part of the cylindrical hole a hollow conical swirler is fixed, the conical shell of which is fixed by means of at least three spokes fixed at one end to the conical shell of the swirler
