Patent number: 6158721Abstract: A small flow of a water with a high carbon dioxide content (normally a carbon-dioxide-saturated water) is produced using hollow-fiber membranes, and is uniformly mixed with a large flow of untreated water with constant proportions. Since the hollow-fiber membrane module has a reserve capacity for adding carbon dioxide to the water, the resistivity of the mixed water is maintained at a constant level by maintaining constant proportions of the small and large flows, even if the total flow rate fluctuates due to fluctuations in the rate of water used in a subsequent process. Accordingly, no automated control device is particularly necessary in order to maintain the resistivity at a constant level. Therefore, a compact and simple apparatus can be produced which can operate at a low cost.Type: GrantFiled: November 20, 1998Date of Patent: December 12, 2000Assignee: Dainippon Ink and Chemicals, Inc.Inventors: Hitoshi Katou, Kazunari Sakai, Toshio Kambe, Kazumi Oi

Patent number: 5518666Abstract: In an apparatus and method for maintaining a desired (target) carbonation level in a carbonator, a control-signal originates from a reference standard of carbonated water close to the target carbonation level, which is sealed inside a pilot chamber of the regulator. The pilot chamber is exposed to the water temperature in the carbonator and is shaped and sized so as to promote rapid equalization of the temperature of the reference standard with that of the carbonated water. The pressure inside the pilot chamber is equal to the equilibrium vapor pressure, according to the temperature and carbonation level of the reference standard. This pressure is transmitted through a flexible membrane in one of the walls of the pilot chamber to a valve in the gas-supply line of the carbonator.

Patent number: 5474717Abstract: Apparatus for mixing fresh water with CO.sub.2 gas to produce carbonated water in a cooled storage tank, includes a space located along the wall of the storage tank adjacent the cooling coils of a cooling system where water flow is partially or fully impeded so that ice can crystallize during the formation of an ice bank in the storage tank. In one configuration, the space is provided by a small section of open pipe mounted on the storage tank wall in the area of the cooling coils. Another configuration includes an apertured structure of rectangular cross section located on the tank wall. Still another configuration consists of an outward projection of a section of the wall of the storage tank which extends between two cooling coils, with an apertured plate covering this projection. Such a space can also be realized by a roughened wall section surface in the immediate vicinity of the cooling coils.Type: GrantFiled: April 19, 1995Date of Patent: December 12, 1995Assignees: The Coca-Cola Company, Bosch-Siemens Hausgerate GmbHInventors: Bernhard Bucher, Raimond Gatter

Patent number: 5464124Abstract: Carbonator apparatus used in connection with a postmix beverage dispenser system includes a water delivery branching circuit for the water fed under pressure from a fresh water source and which is used to fill a storage tank for carbonated water produced therein and to supply fresh water to a recirculating type of fresh water cooling structure which includes a water circulating coil located in the bottom of the storage tank and/or a water channel guide located on the outside of the storage tank. The branching system selectively enables fresh water to be fed into a carbonator storage tank where the water is blended with CO.sub.2 gas or is guided around it while being cooled without being carbonated so that either cooled carbonated water or non-carbonated water is delivered to a mixing station along with a drink concentrate.Type: GrantFiled: April 28, 1994Date of Patent: November 7, 1995Assignees: The Coca-Cola Company, Bosch-Siemens Hausgerate GmbHInventors: Werner Weyh, Udo Schwander, Raimond Gatter, Robert Notar, Helmut Konopa, Klaus Erdmann

Patent number: 5443763Abstract: Apparatus including a circulating pump inside a carbonator tank which blends CO.sub.2 with still water and which is started and stopped for predetermined time periods in repetitive cycles having an on/off ratio ranging between 1:10 and 1:20. A timing circuit controls the operating and non operating times of the circulating pump so that sufficient carbonation of the water with CO.sub.2 gas is achieved along with the formation of an ice bank on the cooled wall of the storage tank. During intervening periods when the circulating pump is not operating, the carbonated water arranges itself in layers according to its density so that the relatively warmer water sinks while the colder water together with any ice particles or small pieces of ice floating therein join together, becoming fixed to the ice bank in the upper portion of the carbonator.Type: GrantFiled: April 28, 1994Date of Patent: August 22, 1995Assignees: The Coca-Cola Company, Bosch-Siemens Hausgerate GmbHInventors: Robert Notar, Udo Schwander
