FIELD: technological processes.

SUBSTANCE: invention relates to the drying of dispersed materials and can be used in microbiological, food, chemical and other industries. Spray dryer comprises a housing with a spray chamber located in its upper part, provided with an acoustic nozzle and a collector for supplying a heat carrier. Acoustic nozzle contains a housing with a generator of acoustic oscillations in the form of a conical nozzle and a resonator, nozzles for supplying air and liquid. External diffuser is coaxially attached to the nozzle casing, and an internal perforated diffuser is coaxially attached to a fastening element of an annular cavity resonator with a resonator rod in such a way that the output cross-sections of the external and the internal diffusers lie in one plane perpendicular to the axis of the annular cavity resonator, and an additional flow divider is coaxially attached to the external diffuser, made in the form of a cylindrical shell, on the end part of which, on the side opposite to the diffuser, a perforated plate is fixed.

EFFECT: increased drying performance.
