APPARATUS AND METHOD FOR PRODUCING DISPERSIONS AND SOLIDS

摘要

The present invention relates to an apparatus and method for producing dispersions and solids by controlled precipitation, coprecipitation and self-organization processes in a microjet reactor, wherein the jet of a solvent (2) comprising at least one target molecule is At the impact point (K) of the reactor chamber of the reactor collides with the jet of non-solvent (3) at a prescribed pressure and flow rate, and the microjet reactor has a gas inlet (5) and gas for introducing gas into the reactor chamber (1) It has a reactant outlet 6 for discharging the reactants into a stream of. This leads to very rapid precipitation, coprecipitation or chemical reactions in which microparticles or nanoparticles are produced. In order to provide an apparatus capable of performing solvent/non-solvent precipitation to produce as small particles as possible and not significantly affected by Ostwald ripening in the resulting dispersion, the present invention provides a spray-drying unit 7 at the outlet of the reactant. It is proposed to provide a control circuit 11 to connect and optimize and maintain the operating parameters of the spray-drying unit 7.
