The patent application describes a device for preparing coffee that aims to prevent the freshly brewed coffee from being cooled as it travels from the brewing unit to the beverage outlet.

The device can be controlled by a programmable controller to vary the quantity of coffee dispensed and to drain away parts of the coffee beverage during the brewing operation. The patent application provides detailed descriptions of the device and its various components. The assignee for this patent application is FRANKE Kaffeemaschinen AG. [Extracted from the article]
