ABSTRACT:
An apparatus for applying a coating to a powdery or granular material has a rotary drum 20 including a tubular portion 21 formed with air holes 27 and hollow shaft portions 23 and 24 provided at opposite end portions in the axial direction. A coating chamber 26 is defined inside the rotary drum 20. Liquid is sprayed from a nozzle 32 onto an accumulated layer 33 of a powdery or granular material in the coating chamber 26. Drying gas supplied from an air supply duct 45 is introduced into the rotary drum 20 from one of the two hollow shaft portions 23 and 24. A plurality of axially extending air ducts 34 are provided on the outer periphery of the rotary drum 20. When an air duct is positioned downwardly it is communicated with an air exhaust duct 41 through a distributor 35. Air introduced from the air supply duct 45 is biased toward the accumulated layer 33 by louvers 48.
