Apparatus and method for micron and submicron particle formation, nozzles for carrying a solution into the vessel for micron and submicron particle formation

摘要

Generating equipment sub micrometer and submicron particulate matter using the GAS process, comprising a container (22) to create particles and means to implement solution of the substance and the supercritical fluid into the container (22) to produce particles, which comprises the nozzle (27) with a central mouth (39), which serves to conduct current solution, as several separate external mouths (41), which serve to drive with clean supercritical fluid or supercritical fluid stream, mixed with the modifier so that the solvent is extracted from a solution of supercritical fluid and precipitation occurs sub micrometer and submicron particles. It also describes a process carried out with such a device.
