Publication number: 20210251418Abstract: A coffee appliance includes a powered cooling system integrated with and matched to a hot coffee brewer, configured to cool freshly-brewed coffee by thermal contact to chill a small batch of fresh-brewed coffee in a cooled receiving vessel. The vessel has an evaporator coil to ice the beverage. The cooling system is a robust system, a phase change refrigerant compression-type system employing a positive-displacement compressor, sized in relation to its rate of thermal cooling and the temperature of the beverage and the thermal mass and conductivity of the fluid-contacting assembly, bringing hot coffee to an ice-cold temperature, 2-5° C., on demand and quickly. The fresh brewed, flash-cooled coffee has undiluted and undegraded flavor. An integrated appliance includes a coffee brewer and cooler in a single device, and a slide switch or valve allows the user to select hot or iced coffee.Type: ApplicationFiled: May 4, 2021Publication date: August 19, 2021Inventors: David Dussault, Benjamin J.

Patent number: 10836651Abstract: A water distiller provides distilled water from an input water supply for domestic, clinic, studio, hospital or factory applications with greatly improved energy efficiency. Stages of the distiller may employ under pressure conditions and/or various vapor compression, heat pump or intermediate process arrangements to provide efficient heat transfer and heating, without requiring boiling of the full input water volume. Enhanced mixing and/or heat transfer may be effected by passing water vapor through the water heating pool and result in clean, efficient distillation in a unit designed for a defined rate or volume of distillate or small system. Embodiments of the invention require less energy than required for comparably-sized direct boiling systems, and may be configured to purge gases or impurities to attain, or maintain, clean heat transfer surfaces and a desired level of product purity.Type: GrantFiled: April 7, 2020Date of Patent: November 17, 2020Assignee: Winter Hill Technologies, LLCInventor: David Dussault
