Abstract: The invention relates to an injector (21) for the addition of a granular solid to a mixing chamber, comprising a central pipe (3) for the addition of the granular solid, an addition apparatus (5) which surrounds the central pipe (3) and is intended for the addition of a propellant gas, wherein the central pipe (3) and the addition apparatus (5) which surrounds the central pipe (3) form an annular gap (9) at the end of the central pipe (3), and also a mixing section (11) with a constant cross section, which adjoins the annular gap (9), and a pipe portion (31) having an outlet opening subsequent to the mixing section (11). The pipe portion (31) having an outlet opening has a change in cross section from a circular inlet cross section to a non-circular outlet cross section of the outlet opening and is rotatable about a central axis.
