Abstract: A coffee maker comprising both a mill assembly for grinding coffee beans, and a brewer assembly underlying the mill assembly for receiving coffee grains filtered out therefrom and for brewing coffee with heated water poured onto the coffee grains. The mill assembly has a mill housing having its top closed by a mill cap adapted to receive the heated water from a water heater. Projecting from the mill cap, in a position just over a coffee grain filter constituting a part of the mill assembly, a water chute conducts the heated water down onto the coffee grains that have been fed from the mill assembly into the brewer assembly. The interior of the mill housing is therefore not wetted with the heated water during the brewing but can be kept dry to allow immediate resumption of grinding as desired.

Abstract: Even if freshly roasted and freshly ground coffee is used when percolating hot coffee, much or at least part of the fragrances and aromas originally contained in the coffee beans disappear into the environment instead of staying with the brew, therefore, in order to save these aromas and fragrances, a method and an apparatus is suggested with the help of which roasting and grinding of the coffee beans take place inside the flask where the beverage gathers, thus assuring that all or most of the aromas and fragrances generated during roasting and grinding stay contained in the flask until the coffee is served.

Abstract: This invention relates to a process and apparatus for the production of an aroma flavor concentrate from aroma- and flavor-bearing substrates, especially roasted and ground coffee. More particularly, the invention is concerned with a process for continuously de-aromatizing and desorbing aroma and flavor constituents from said substrates by passing wet steam counter-currently through a continuous columnar bed of said substrate, said bed flowing upwardly through a substantially upright vacuum-tight desorption column. Wet steam is applied in an amount and manner to form and maintain a substantially stationary desorption zone in said flowing columnar bed at a finite distance above a bottom inlet of said upright desorption column. The stationary desorption zone is formed by the condensation of the wet steam as it passes into a progressively cooler temperature gradient in said flowing columnar bed.
