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.

Abstract: An apparatus for producing coffee or other beverages has two brewing cylinders and brewing pistons which are movable in the brewing cylinders and which form a brewing chamber. A loading station is provided for loading the brewing chambers with ground coffee or the other media. One brewing cylinder can be moved in each case together with the associated brewing piston from a brewing position to the loading station and back again, wherein the associated brewing piston can be removed for the disposal of the used coffee or medium from the brewing cylinder. The second brewing cylinder can therefore be moved to the same loading station as the first, and this therefore results in a simplification of the design of the apparatus.

Abstract: During a method for the production of milk foam or milk-based drinks, milk is sucked with a pump (1) out of a container (3, 3?) and conveyed to an outlet (11?), wherein air and/or a gas is added to the milk. The milk/air mixture is processed in a cold state into milk foam and conveyed as cold milk foam to the outlet (11?).

Abstract: An apparatus for producing coffee or other beverages has two brewing cylinders (2; 2?) and brewing pistons (10, 11; 10?, 11?) which are movable in said brewing cylinders and which form a brewing chamber. A loading station is provided for loading the brewing chambers with ground coffee or the other media. One brewing cylinder (2; 2?) can be moved in each case together with the associated brewing piston (10; 10?) from a brewing position to the loading station (5) and back again, wherein said associated brewing piston (10; 10?) can be removed for the disposal of the used coffee or medium from the brewing cylinder (2; 2?). The second brewing cylinder (2?) can therefore be moved to the same loading station (5) as the first, and this therefore results in a simplification of the design of the apparatus.

Abstract: An apparatus for producing milk drinks or foamed milk drinks, especially for a coffee machine, is envisaged with a capsule (1, 1?, 1?) containing a pre-determined quantity of milk for a single use. The capsule (1, 1?, 1?) can be positioned above an outlet (2) and heated. In addition, a device for opening the floor (9, 9a) to extract the milk from the capsule (1, 1?, 1?) should be provided so that air can be added to the milk exiting from the capsule (1, 1?, 1?) for a possible foaming of the milk. The apparatus is simple and cost-effective and simple to maintain.

Abstract: A coffee machine is provided with a housing frame (10), with at least one extraction device (20) for production of the coffee, an electronic control unit (40) and a hot water or steam supply (50). The extraction device (20), the control unit (40) and the hot water or steam supply (50) are each assigned to a black box (62, 63, 64, 65) provided with at least one transponder or similar for recording certain data and/or registration of certain functional processes. The recorded data can be analysed, notably by a computer program. In this way the coffee machine can be optimally serviced and hence the lifetime of the individual functional units increased.

Abstract: A coffee machine includes a housing frame in which are slidably disposed at least one extraction device, one electronic control unit and a hot-water supply as modules implemented independently of one another. Each modules is provided on a rear side thereof with at least one connector component which in the slide-in state is coupled with a corresponding connector component in the housing frame. The connector components in the housing frame are connected with one another via cables or lines. The coffee machine can be assembled in extremely simple manner, and it is possible in the event of a defect to replace a module without involving an expert.

Abstract: This invention relates to a coffee mill which comprises two grinding devices, each device being formed of a fixed annular grinder (1,1') and a rotary annular grinder (3,3') which are mounted in opposition the one to the other. The grinding devices are coaxially superposed. The rotary grinders (3,3') of the two devices are rotated by a single axle (5,5') connected to a single driving motor (M) with a double rotation direction, and the cutting means of one of the pairs of grinders are oriented for a right hand cutting, whereas those of the other pair of grinders are oriented for a lefthand cutting.

Abstract: The single driven part of the apparatus is an axially movable scalding cylinder, in which a piston is located which is free to move in the axial direction. This piston is positioned by a guide bush or moved with the scalding cylinder. A supporting block comprises, furthermore, an abutment for the disk of the piston. A second piston is arranged stationary or may be moved also axially against the force of a spring against a further supporting block. By the movement of the scalding cylinder ground coffee which has been inserted between the pistons is compressed and drinkable coffee is produced by feeding hot water thereto.
