  • Patent number: 10791870
    Abstract: A device and a method for heating and foaming a liquid, in particular a beverage such as a milk-containing beverage for example. The device comprises a steam generator, a pressurized gas source, and a pump means which is connected to the steam generator and the pressurized gas source for transporting a steam/gas mixture into the liquid. The pressurized gas source comprises a controllable switching valve in order to generate pressure pulses. The pressure pulses generated by the pressurized gas source are introduced into the pump means and mixed with the liquid in the pump means, whereby the liquid is foamed. The foam properties of the foamed liquid, such as consistency, creaminess, density, and porosity, can be influenced by the frequency, amplitude, and pulse duration of the pressure pulses.

  • Patent number: 10004355
    Abstract: A system for preparing milk and milk foam in drink machines, such as coffee machines and similar pieces of equipment, which are provided with a heater unit for heating the milk and/or the milk foam with steam, contains a feed for the milk and/or the milk foam and a separate feed for the steam, which is fed directly, as a heat-transfer medium, into the milk and/or the milk foam in the heater unit, which operates as an injector.

  • Publication number: 20170238755
    Abstract: An appliance for heating and/or frothing milk, in which steam or a mixture of steam and air acting as a heat carrier is injected into the milk, with the heating unit including an inner steam channel and an outer annular channel for the milk. The outer annular channel coaxially surrounds the inner steam channel, with hot steam or a mixture of steam and air being supplied at an upstream end of the steam channel and with milk being supplied at an upstream end of the annular channel. To improve the heat output and the energy efficiency of the heating unit and to reduce the maintenance requirement, the steam channel and the annular channel are separated from one another, with their downstream ends opening out into an outlet channel for discharging the heated and/or frothed milk.

  • Publication number: 20130112231
    Abstract: The invention relates to a cleaning system for coffee machines, comprising a cleaning device for periodically cleaning the coffee- and/or milk-carrying components using a cleaning liquid, which contains cleaning agent in the form of balls or tablets dissolved therein, wherein the cleaning device is provided with a time- and/or product-cycle-dependent controller and a metering apparatus (1) for the cleaning agent (10) that interacts with the controller. Thus, it is possible to program the cleaning process in a customized manner according to the mode of operation and to carry out the cleaning process fully automatically according to the program. The metering of the cleaning agent (10) according to the program ensures an always optimal cleaning effect together with sparing use of cleaning agents. Simple and safe handling is achieved by using ball- or tablet-shaped cleaning agents.
