Subject of the invention is a device for coating particles, which belongs to the field of chemical and pharmaceutical technology and represents an enhancement of the process equipment for coating particles by spraying from bottom and is based on the operating principle of vortex technology. Inside the walls (1), the processing device according to the invention features one or several units, while each unit consists of a generator (4) of an air vortex with a perforated panel (3) and a delimiting cylinder(5), where centrally through the generator (4) of the air vortex a single- or multi-phase nozzle (6) for spraying is inserted with supply (7) for the dispersion and coating as well as a supply (8) of compressed air. The air vortex generator (4) features grooves (18) on the external side which are externally open and under an angle regarding the vertical axis. The processing device for coating particles in the second invention implementation option inside walls (1) features one or several units, while eachunit consists of a delimiting cylinder (5) and a single- or multi-phase spraying nozzle (6), which is located centrally regarding the cylinder and penetrates the perforated panel (3a). The perforated panel (3a) is on its external side, between the wall of the delimiting cylinder (5) and device wall (1) in its cross section either even or bent and features a typical distribution of the sizes of circular openings with the maximum diameters in the area of the ground plan projection of the delimiting cylinder(5) and smaller openings in the remaining part of the panel. The device for coating features intake nozzles (27) around its wall (1) circumference along the perforated panel (3) into the ring (21) applied slant regarding the circumference, where pressure is supplied from the common hollow ring (20) with compressed air adapter (22). The coating device features along the circumference of the wall (1) over the perforated panel (3) a radially applied circumferential slot
