SPRAY DISPENSER PROVIDED WITH A DISK ROTATING CALIBRATED AEROSOLS

摘要

The invention relates to a spray dispenser provided with a rotary disc generating with a high rate calibrated aerosol in such a way that drops are monodispersed and have a low statistical straggling of the diameters thereof around a defined mean value or multidispersed by splitting into defined sized main drops and a discrete spectrum of small-sized also defined satellites. The drop control is carried out by controlling waves propagating through a jet and by fractionating them. Said control is carried out by oscillating a deformable or rigid disc or by exciting jets by means of fine teeth which are uniformly distributed along the disc circumference. The inventive device is directed, in particular to industrial, medical and agricultural applications where it is necessary to produce supermicron drops and where monodispersion is a quality factor
