Patent number: 7651074Abstract: This invention concerns an apparatus and a method for producing carbonated water capable of obtaining high concentration carbonated water effectively. Carbon dioxide gas is passed through a first carbon dioxide gas dissolver composed of a membrane module to be dissolved in water and the carbonated water passing through the first carbon dioxide gas dissolver is passed through a static mixer, which is a second carbon dioxide gas dissolver. Consequently, a high concentration carbonated water can be obtained remarkably, effectively and easily with a simpler structure than conventionally.Type: GrantFiled: September 25, 2008Date of Patent: January 26, 2010Assignees: Mitsubishi Rayon Co., Ltd., Mitsubishi Rayon Engineering Co., Ltd.Inventors: Ken Ooyachi, Hiroki Sakakibara, Hiroshi Tasaka, Masaaki Satou, Masanori Itakura, Katsuya Sanai
