FIELD: technological processes.
SUBSTANCE: invention relates to the drying of dispersed materials and can be used in microbiological, food, chemical and other industries. Drying plant with an inert fitting contains a casing with a gas distribution grid and a material feeding atomizer, and inside the housing, coaxial to it, there is a heated chamber, to the bottom of which a pipe with radial holes and an expanding nozzle with a gas distribution grid for supplying an additional heat transfer medium is connected, and the product spraying nozzles are made in the form of at least one acoustic atomizer comprising a housing with an internal acoustic oscillation generator in the form of an nozzle and a resonator. Sprayed fluid is supplied through the branch pipe, located perpendicular to body axis, to annular cavity formed by casing and nozzle external surface. At the same time, one end of the casing is made solid and connected to the casing. External diffuser is coaxially attached to the nozzle casing, and an inner perforated diffuser is coaxially attached to the fastener of the annular cavity resonator with the resonator rod in such a way that the output sections of the external and internal diffusers lie in one plane perpendicular to the axis of the annular volumetric resonator. Additional flow diffuser, made in the form of a cylindrical shell, is coaxially attached to the external diffuser of the acoustic nozzle, on the end part of which, on the opposite side of the diffuser, a perforated plate is fixed.
EFFECT: increase in drying performance.
