Patent number: 8157899Abstract: A particulate material processing apparatus has a vessel and a processing tank. The vessel has a charging port for charging a particulate material into the vessel. The processing tank receives the particulate material charged from the charging port. The processing tank is shaped so as to narrow towards the bottom. At least the lower part of the processing tank is made of a gas-permeable material that allows the process gas for processing the particulate material to pass through. The upper part of the processing tank has lower gas permeability than the lower part of the processing tank.Type: GrantFiled: November 14, 2008Date of Patent: April 17, 2012Assignee: Daikin Industries, Ltd.Inventors: Tomohiro Isogai, Katsuya Nakai, Tatsuo Suzuki, Taku Hirakawa, Hiroyuki Shimada
