COLDWAVE APPLIANCE
Abstract:
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.
