Abstract:
A machine for coating granular articles and the like, comprising:a rotating drum or coating pan (1) rotating around a rotational axis and containing a predetermined mass of articles to be treated; a tubular manifold (4) having an axis parallel to the rotational axis of said coating pan (1) and set in communication with an outer first pipe (5); a plurality of perforated hollow bodies (14), extending from said manifold (4) and being dipped into the moving mass of said articles being treated, said perforated hollow bodies (14) being telescopic for adjustment of their length to change a depth of penetration into the moving mass of said articles inside the coating pan (1); a second pipe (6) connected to said coating pan (1) to create a flow of air for ventilating said articles; said perforated hollow bodies having a distal part (14b) open at the bottom when the distal part is not mounted on a terminal portion and closed at the bottom when mounted to the terminal portion and has opposite surfaces with perforated areas (12); said distal part (14b) being inclined with respect to a vertical axis of the hollow body and having an oblong cross-section with pointed ends.
