US 5,842,407 A · Apparatus for preparing filter coffee

Abstract

In order to generate steam in an apparatus for preparing filter coffee, a design is proposed which comprises a water storage container and a device for separating water and steam. A heating element is provided for heating water and for generating steam. The separating device comprises an inlet connected to the outlet of the heating element and an outlet connected to a steam nozzle. The water storage container comprises an inlet connected to a fresh water tank and an outlet connected to the inlet of the heating element. Moreover, a throttle member is provided close to the outlet of the water storage container; the throttle member restricts, during the generation of steam, the amount of water fed to the heating element per unit of time. By such a design, dry steam, particularly suitable to prepare a cappuccino beverage, can be generated in a simple manner.
