Abstract: A pulverization head of an apparatus includes a motor whose vertical hollow shaft is integrally linked, at its lower end, to a centrifugal ejection disc. The substance to be pulverized, coming from a tank via a proportioning pump, crosses the hollow shaft to be spread in a thin layer on the lower surface of the disc forming the centrifugal ejection face. Elements are designed to vibrate the peripheral edge of the disc and control the pulverization of the substance. A fan and a distributor produce a treatment gas flow which meets and draws droplets towards a collection zone, solidifying them by drying or freezing. Typically, the substance is a mixture of at least one active ingredient and a microencapsulation constituent. For use to obtain very fine and/or very homogeneous particle size, to manufacture powders for food processing, nutritional, cosmetic, pharmaceutical and fine chemical applications. The head is useful to produce aerosols.

Abstract: The invention relates to an atomizer, which has a rotating disc, is miniaturized and which is easily portable. Numerous uses exists according to the power source used. When the source of energy is a battery, this system, which is autonomous and portable, is particularly suited for domestic uses. When the power source is the mains supply or pneumatic, this system, which is portable, is particularly suited for industrial uses, and when the power used is renewable, this system, which is autonomous, is especially for uses in an isolated medium, for example, for desalinating sea water or oxygenating lagoon systems. The atomizer is principally composed of: a rapidly rotating disc; a system for supplying liquid to the disk; a fan enabling the aerosol to be directed in the desired direction; a motor; the power source thereof, and; control and checking devices. The invention is characterized by the fact that the functions of spraying, pumping and fanning are effected by the same rotor.
