COATING APPARATUS

摘要

A rotary drum (2) rotates around an axis (A) inclined at a predetermined ang le (.theta.) with respect to the horizontal. A treating gas flows from the ventilation port (7a) of a ventilation duct (7) into the rotary drum (2) through a gas supply port (5) at one end of the rotary drum (2) and passes through a particle layer (11), flowing out into an exhaust duct (8) through the ventilation port (21a) of a first disk plate (21) and the communication port (22a) of a second disk plate (22).
