FIELD: technological processes.SUBSTANCE: invention relates to the technology of drying disperse materials in a fluidized bed and can be used in aniline, food, pharmaceutical, microbiological, food, chemical and other industries. Spray dryer fluid bed with inert packing contains a body with gas distribution grid, vibrating plates, nozzle, vibrating mechanism. Nozzle of the wet feed source feeder comprises a cylindrical body with a fitting rigidly connected to the body and coaxially disposed in the upper part of the housing and having a cylindrical fluid inlet connected to a diffuser that is axisymmetric to the body 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 in its upper part, and at other end – in the annular groove made on the inner surface of the cylindrical hole, on the outer surface of the hollow conical swirler a screw through
