The invention relates to a device for coating or encapsulating particles, including a drum (2) which is mounted in a drum chamber (1) of the device in a rotationally drivable manner and which drum (2) can be filled with the product to be coated or to be encapsulated, at least one spray nozzle, which is provided for applying a liquid to the product that is located in the drum (2), at least one drying gas inlet (5) that penetrates the chamber wall of the drum chamber (1), through which drying gas inlet a drying gas can be introduced into the drum chamber (1) and including at least one drying gas outlet (9) that is near the drum (2) on the outer side for channeling the drying gas out of the device. The device according to the invention is characterized in that a deflector surface (6) is interposed in the flow path between the at least one drying gas inlet (5) and the drum (2), which deflector surface defines at least one flow-through opening (7), the total clear opening surface area of which is smaller in comparison to the total clear opening surface area of the at least one drying gas inlet (5). By means of the deflector surface (6) it is achieved that the drying gas flows out of the at least one flow-through opening (7) in a uniform and decelerated manner, so that irregular coatings of the product or the appearance of function-impairing build-ups in the drum chamber (1) are effectively prevented. |
