Abstract: A process device for coating particles in which, on the inside wall (1), there are one or more units installed. Each unit includes a swirl flow generator (4) around which a straight or curved perforated plate (3) and draft tube (5) are located in cross-section. A single or multi-phase spraying nozzle (6) is installed centrally through the swirl flow generator (4) with a conduit (7) for dispersion for coating and a conduit (8) of compressed air. The swirl flow generator (4) has at an angle from the vertical adjacent grooves (18) that open outwards, with the angle of grooves (18) to the vertical line are between 10 and 45°.

Abstract: The subject of the invention is a process device for coating particles that falls within the field of chemical and pharmaceutical technology. It represents an improvement on the process equipment for coating particles by spraying from the bottom and works on the principle of fluidization technology. The process device for coating particles, according to the invention which has within the wall (1), one or more units placed, for which each unit consists of a swirl flow generator (4) with a perforated plate (3) and a draft tube (5) where centrally through the swirl flow generator (4) a single or multi-phase spraying nozzle (6) with a coating dispersion inflow (7) and inflow (8) of compressed air is installed, in which the swirl flow generator (4) has outward open and at an angle with regard to the vertical installed grooves (18).
