Method and apparatus are provided for efficient metal distillation, and for related primary product process. Vertically stacked and gravity-driven evaporators and condensers are employed to distill metals, such metals having different volatilities. A multiple-effect thermal system of magnesium and other volatile metals is used to efficiently distill and separate metals from multiple metal alloys.

Method and apparatus for efficient metal distillation and related primary production process

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&#xb0; 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.

Coldwave appliance

Disclosed is a beverage chiller having a bottom portion and a top portion. The bottom portion includes a perimeter wall defining a receiving vessel for receiving a beverage to be chilled. The top portion includes at least first and second cooling tubes. The bottom and top portions interfit such that the cooling tubes extend vertically down into the beverage and chill the beverage to a desired temperature by thermal contact with said cooling tubes when the top portion is positioned on the bottom portion. The first and second cooling tubes have first and second perimeters, respectively, within a horizontal cross-section of the top portion, and the first and second perimeters have substantially a same size and shape.

Beverage chiller employing array of heat exchange tubes

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.

High efficiency improved water distillation unit and methods of operation

A fluid cooling apparatus includes a first cooling portion have a first series of cooling elements with first cooling surfaces. A second cooling portion can have a second series of cooling elements with second cooling surfaces. The second cooling portion can be removably nested together with the first cooling portion such that the first and second cooling surfaces of respective first and second series of cooling elements can be positioned adjacent to each other with gaps therebetween to form cooling cavities for cooling fluid introduced into the cooling cavities.
