    • The invention relates to a device for coating particles (10), comprising a container (12) with a perforated flow contact floor (14) through which an upwardly-flowing process gas (15) can be delivered; at least one ascending tube (24), which is located in the container at a distance from the flow contact floor, whose top end is open to the container, and in whose bottom end a spray nozzle (18) for spraying coating material into the ascending tube is arranged. A coating area (32) is formed inside the ascending tube and a feedback area (37) is formed outside said ascending tube. Means for delivering a supporting gas (62) are provided in or on the container near the perforated flow contact floor, these means guiding in a supporting gas flow in the direction of the gap with at least one flow component that is oriented inwards, sideways, in order to form a sliding gas layer and to transport the particles between the feedback area and the coating area in a directed particle flow. In addition or alternatively, constructional shaping means (22), (120) are situated in the bottom area of the container, said means forming a transition channel between the feedback area and the coating area with essentially constant peripheral surfaces.
    • 有在提供一种用于涂覆颗粒(10),其具有具有穿孔的气体分配器板(14)的容器(12)由从下到上的工艺气体(15)的流速供给装置,具有至少一个随着距离的分配器板 容器设置立管(24),其是在其上端与容器打开,并在其下端具有喷嘴(18),用于喷射引导到提升管涂层材料已被提出。 内的立管是一个涂覆区(32)和所述上升管的再循环区域(37)的外侧形成。 在穿孔流入底部附近装置,用于支撑所述气体的供给(62)设置在或在容器上的支撑气体流与至少一个从外部横向指向内部流动分量在所述间隙的方向上形成气体轴承表面和用于传输返回区之间的颗粒 涂覆区排放到定向粒子流和/或在容器中的装置(22,120),布置成形成建设性,其形成返回区,并用基本恒定的限定表面的涂层区之间的过渡通道的下部区域中。
