Abstract: An installation for guiding a gas for devices used to treat granular products by drying, film-coating or coating includes: a central distribution channel that can be connected to a gas supplying device and is connected to outlets for the gas, that are arranged at a distance from the central distribution channel in an axial direction, via connection channels. The installation includes a functional channel which is arranged at a distance from the distribution channel and has a plurality of outlets, and the functional channel includes at least two axially interspaced inlet regions, each being connected to the distribution channel via a connection channel. The outlets are arranged, in the axial direction on the functional channel, between the mouth of two connection channels, which are adjacently arranged in the axial direction, in the functional channel.

Abstract: The invention relates to an installation (1) for guiding a gas for devices (44) used to treat granular products (56) by drying, film-coating or coating, especially an air intake unit, comprising a central distribution channel (2) that can be connected to a gas supplying device and is connected to outlets (6.1, 6.n) for the gas, that are arranged at a distance from the central distribution channel in an axial direction, by means of connection channels (3, 4). According to the invention, the installation comprises a functional channel (5) which is arranged at a distance from the distribution channel (2) and has a plurality of outlets (6.1, 6.n). Said functional channel comprises at least two axially interspaced inlet regions (11, 12). Each inlet region (11, 12) is connected to the distribution channel (2) by means of a connection channel (3, 4). The outlets (6.1, 6.
