  • Cryogenic liquefying/refrigerating method and system
    Patent number: 7540171
    Abstract: Cryogenic liquefying/refrigerating method and system, wherein temperature of gas-to-be-liquefied at the inlet of the compressor for compressing the gas is reduced by cooling the gas discharged from the compressor using a high-efficiency chemical refrigerating machine and vapor compression refrigerating machine before the gas is introduced to a multiple stage heat exchanger thereby reducing power input to the compressor and improving liquefying/refrigerating efficiency.
    Type: Grant
    Filed: May 15, 2007
    Date of Patent: June 2, 2009
    Assignee: Mayekawa Mfg. Co., Ltd.
    Inventors: Nobumi Ino, Takayuki Kishi, Toshio Nishio, Akito Machida, Yoshimitsu Sekiya, Masami Kohama, Masato Noguchi

  • Pasteurizer
    Patent number: 6588327
    Abstract: An energy and water saving pasteuriser capable of maintaining a stable temperature distribution pattern even when transfer work are interrupted during the operation, or a tunnel type refrigerator (10) allowing hot work such as bottles and cans filled with the products sterilized at a high temperature of generally 75° C. to allow temperature of generally 25° C., wherein plural cooling vessels (11a, 12a, 12b, 12c, 12d, 13a, 13b) are disposed in a row from the upstream side to the downstream side so as to form a first cooling region (11), an intermediate cooling region (12), and a final cooling region (13), an adsorption freezing machine (19) is installed between the first cooling region (11) and final cooling region (13), and a cooling tower (20) is installed in the intermediate cooling region (12).
