FIELD: machine engineering.

SUBSTANCE: in the vortex spray drier, the liquid sprayer can be implemented in two variants according to Fig.3 and Fig.4. According to the invention, an outer diffuser is coaxially fixed to bushing of the liquid sprayer rigidly connected with body in its lower part, and an inner perforated diffuser is coaxially connected to the lower base of truncated cone of the sprayer rigidly fixed to central core in its lower part so that the outlet sections of the outer and inner diffusers lie in the same plane. Helical grooves are provided on outer side surface of truncated cone.
