Patent number: 5344621Abstract: An autoclave for treating charged materials (6) with vapor under pressure, with a substantially cylindrical inner chamber (2) surrounded by an autoclave casing (1) and with a heating device (8) responsive to a heated heat transfer medium to generate vapor in the inner chamber (2). In order to provide the heating in a way which is favorable structurally and in terms of energy, it is provided that the heating device (8) is arranged within one of the curved side regions of the autoclave casing (1), and consists of at least one flue (10) arranged substantially vertically in the autoclave and a heat exchanger (11) arranged in the lower inflow region of the flue (10) and through which flows a heat transfer medium, so that a convection flow results circulating substantially in the circumferential direction of the casing (1) of the autoclave.Type: GrantFiled: October 20, 1992Date of Patent: September 6, 1994Assignees: Hebel Aktiengesellschaft, Sicowa Verfahrenstechnik Fuer Baustoffe GmbH & Co.

Patent number: 5326542Abstract: An ultraviolet (UV) sterilization system for food cartons is disclosed. An elongated UV lamp is mounted in a housing. A parabolic cylinder reflector is mounted in the housing with the focus of the reflector coinciding with the axis of the arc in the UV lamp. The shape of the parabolic reflector directs radiation from the lamp into cartons positioned on a conveyor below the lamp. The axis of the arc is parallel to the direction of movement of the cartons on the conveyor. The front surface of the reflector also absorbs heat from the lamp and heat is removed from the reflector by circulating air over the back surface of the reflector.Type: GrantFiled: October 1, 1992Date of Patent: July 5, 1994Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Charles E. Sizer, Terry D. Erickson, Terrence F. Manley

Patent number: 5258162Abstract: A method of producing a gaseous, hydrogen peroxide-containing sterilization fluid displaying good, uniform sterilization properties is disclosed. The method includes vaporizing liquefied hydrogen peroxide by injecting the liquefied hydrogen peroxide intermittently in finely-divided form into an air current which serves as a vaporization agent, wherein the air current is kept at a constant or insignificantly varying elevated vaporization temperature. An even vaporization temperature of the air current is ensured because the air, prior to vaporization, is heated by heat exchange with a heating element having a large mass or thermal capacity and a large heat exchange surface area which is kept at the desired elevated temperature by regulated energy supplied to the heating element. During breaks in vaporization between the intermittent injection of the liquefied hydrogen peroxide, the heat exchange surface area is heated with the aid of heat stored in the heating element.Type: GrantFiled: July 31, 1992Date of Patent: November 2, 1993Assignee: Tetra Alfa Holdings S.A.Inventors: Jan Andersson, Lars Martensson, Thomas Bjerborn, Goran Smith

Patent number: 5246674Abstract: A container for use in a microwave apparatus, in particular for heating, drying, disinfecting and/or sterilizing of materials, objects, liquids or the like, includes a lid securely attachable via a pressure lock to the container and including connections for allowing attachment of various valves, pumps etc. to monitor and influence conditions in the container. The connections are self-sealing plug connector pipes which are engageable with a complementary coupler piece of the microwave apparatus. The microwave apparatus includes an injector unit by which water or other liquid is introduced into the material to be treated, with the amount of injected water being dependent on the water content of the material. The injector unit includes a nozzle head which projects into the treatment chamber of the microwave apparatus and incorporates sensors for determining physical and/or chemical parameters.Type: GrantFiled: October 23, 1991Date of Patent: September 21, 1993Assignee: Helmut KatschnigInventors: Helmut Katschnig, Leonard Gage

Patent number: 5238660Abstract: An apparatus for cleaning and sterilizing objects, such as pharmaceutical caps, plugs and the like includes an autoclave chamber and a cleaning device having a cleaning drum mounted for a free rotation on a frame. The frame runs on rollers and can be moved in and out of the autoclave chamber. The cleaning drum has a hollow shaft provided within the drum with spray nozzles and mounted axially in line with a hollow drive shaft passing through one sidewall of the autoclave chamber free to turn and sealed. The drum shaft and the drive shaft may be coupled together by a coupling device. The frame may be released from the drum introduced into the autoclave chamber so that it is not located during the cleaning process in the autoclave chamber and thus will not constitute an additional source of contamination.Type: GrantFiled: June 5, 1991Date of Patent: August 24, 1993Inventor: Voelpel Dietwart

Patent number: 5213776Abstract: A sterilizer assembly for sterilizing infant accessories such as baby bottles, nipples, nipple hoods and collars simultaneously, especially in microwave ovens. Preferably, the assembly is formed from heat resistant, nonmetallic, microwavable materials and includes a base defining a receptacle for receiving water to be heated to form steam. A rack is received on the base over the water and preferably includes a plurality of upstanding supports removably mounted over steam passage apertures in the rack. A dome-like hood encloses the rack, supports, and any items to be sterilized. A vent member on the hood may be rotated to uncover an aperture and release steam from the assembly before removing the hood and after heating to avoid burn injuries. Each support will suspend a baby bottle or, alternately, will suspend a nipple hood, mount a nipple and locate a bottle collar all in position for effective steam contact and water drainage.Type: GrantFiled: September 12, 1989Date of Patent: May 25, 1993Assignee: Gerber Products CompanyInventors: Daniel A.
