  • Patent number: 9625744
    Abstract: The present invention relates generally to systems and methods for cleaning and disinfecting contact lenses. In various respects, the invention is directed to an insulated system that reduces heat loss from catalyzed neutralization of a disinfecting solution resulting in an increased temperature of the disinfection solution during the disinfection process and neutralization of the disinfection solution. The increased temperature increases the kill rate (i.e., better reduction) of microorganisms present on the lenses, and increases the neutralization rate of the disinfection solution. Increase of the kill rate allows better reduction of microorganisms resistant to elimination using previous systems and methods, (e.g., Acanthamoeba cysts), and decreases the amount of time as compared to previous systems and methods necessary to reduce microorganisms to acceptable levels.

    Abstract: Disclosed is a substrate processing apparatus capable of drying a substrate to be processed while suppressing the pattern collapse or the occurrence of contamination. A substrate is held in a liquid bath while being immersed in a liquid, and the liquid bath is disposed in a processing space of a processing vessel. A processing of drying the substrate is performed by replacing the liquid in the liquid bath with a supercritical-state fluid. A predetermined mechanism moves liquid bath between a processing location in the processing case and a stand-by location outside the processing case. A heater installed in the processing case changes the fluid to a supercritical state or maintains the supercritical state while cooling mechanisms cool down the liquid bath moved to the stand-by location outside the processing vessel.

  • Patent number: 8459278
    Abstract: A dishwashing machine is provided. The dishwashing machine includes a washing container, at least one device for washing crockery using a washing solution, a heating device, and a sorption drying device communicated with the washing container for the passage of air between the sorption drying device and the washing container. The sorption drying device contains reversibly dehydratable material that operates to withdraw moisture from air during the passage of the air through the sorption drying device. The sorption drying device is housed in a housing and has air passing from the washing container into the sorption drying device via an air inlet and thereafter flowing along a flow path through the sorption drying device and eventually exiting the sorption drying device via an air outlet. The heating device is located upstream of the air inlet relative to the flow of air through the sorption drying device.

  • Patent number: 8307839
    Abstract: A cleaning appliance is provided for cleaning washware, which cleaning appliance is designed to subject the washware to the action of at least one cleaning fluid in at least one cleaning chamber. The cleaning appliance has a suction-removal apparatus for removing damp air from the cleaning chamber by suction, and at least one heat recovery device. The heat recovery device is designed to draw heat from the damp air and to feed it back to the cleaning appliance by means of a first cooling fluid. The cleaning appliance has a cooling-fluid line with at least one recirculation path and at least one heat accumulator path with at least one latent heat accumulator. The cleaning appliance is designed to conduct the first cooling fluid to the cleaning chamber and/or into a fluid tank via the recirculation path in at least one operating state after said cooling fluid has flowed through the heat recovery device.

  • Patent number: 8157924
    Abstract: A warewasher for washing wares includes a housing defining an internal space with at least one spray zone for washing wares. A liquid delivery system provides a spray of liquid within the spray zone. A tank includes an inlet that is connected to a hot water source for filling the tank with hot water. The liquid delivery system receives water from the tank. An exhaust vents heated air from the housing. A final rinse system is connected to a cold water source. A heat recovery system is located between the final rinse system and the cold water source. The heat recovery system transfers heat from the exhaust air to the cold water provided from the cold water source. A valve associated with the hot water source selectively supplements the water exiting the heat recovery system with hot water from the hot water source.
