Abstract
The invention relates to an apparatus and method for the production of dispersions and solids by way of controlled precipitation, co-precipitation and self-organization processes in a microjet reactor, a jet of solvent containing at least one target molecule and a jet of nonsolvent colliding with each other, at specified pressures and flow rates, at a collision point in the reactor chamber of the microjet reactor, and the microjet reactor having a gas inlet for introducing gas into the reactor chamber and an educt outlet for discharging the educts in a stream of gas. This results in very rapid precipitation, co-precipitation or a chemical reaction, during the course of which micro- or nanoparticles form. In order to create an apparatus with which solvent/nonsolvent precipitations may be carried out in such a way as to produce particles that are as small as possible and largely free of Ostwald ripening in the dispersion being formed, it is suggested according to the invention that the educt outlet be followed by a spray-drier unit and that a feedback control system be provided to optimize and maintain the operating parameters for the spray-drier unit.
