Patent number: 10791870Abstract: 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.Type: GrantFiled: October 6, 2016Date of Patent: October 6, 2020Assignee: EVERSYS HOLDING SAInventors: Grégoire Locher, Stéphane Betrisey

Patent number: 10537205Abstract: 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.Type: GrantFiled: February 22, 2017Date of Patent: January 21, 2020Assignee: EVERSYS Holding SAInventor: Grégoire Locher

Publication number: 20190053656Abstract: A beverage machine for producing coffee-based beverages includes a pump supplying pressurized water; a heater heating the water; a brewing chamber, which is fillable with coffee powder; piping in fluid connection with the pump, heater and brewing chamber for conducting pressurized water into the brewing chamber; and a dispensing device dispensing coffee-based beverage produced in the brewing chamber by brewing the coffee powder with the water. The piping has a first feed pipe between the pump and heater and a second feed pipe between the heater and brewing chamber. The second feed pipe has at least a first valve. A cooler is arranged in the second feed pipe downstream of the first valve for cooling water heated by the heater, to enable production of coffee-based beverages having different temperatures, in particular temperatures below 50° C., which allow pouring the produced beverage into a bio-degradable cup made of polylactic acid (PLA).Type: ApplicationFiled: August 13, 2018Publication date: February 21, 2019Applicant: EVERSYS Holding SAInventor: Grégoire LOCHER

Patent number: 9039843Abstract: 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.Type: GrantFiled: June 21, 2011Date of Patent: May 26, 2015Assignee: Eversys Holding SAInventors: Dominique Sierro, Frank Rimpl, Jean-Paul In-Albon, Bernhard In-Albon, Hubert Bruttin

Publication number: 20140299001Abstract: The invention relates to a system for preparing milk and milk foam in drinks 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. The system contains, according to the invention, 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. The system allows a high heating capacity along with simultaneously good regulating capability and minimized thermal inertia. Since the foaming operation and the heating operation are separated from one another, the quality of the milk foam remains unimpaired by the heating operation.Type: ApplicationFiled: October 27, 2012Publication date: October 9, 2014Applicant: EVERSYS Holding SAInventor: Frank Rimpl
