摘要:
A disposable cartridge (10), which is suitable to be used in a process of preparing a beverage, comprises a beverage making unit (1). A duct system (30) of the beverage making unit (1) has a main duct (31), a first subsidiary duct (32) which merges into the main duct (31), and a second subsidiary duct (33) which merges into the main duct (31) as well, at a different position than the first subsidiary duct (32). In a process of preparing a beverage, a first fluid is supplied by the main duct (31), and flows of a second fluid are supplied by the subsidiary ducts (32, 33). In this way, it is achieved that the second fluid is mixed with the first fluid in two steps. In case the second fluid is used for heating the first fluid, local boiling of the first fluid is prevented.

A pump unit includes a reservoir for containing a liquid, a duct system for conveying the liquid, and a pumping section for subjecting the liquid to a pumping force. The initial filling of at least a portion of a duct for conveying the liquid from the reservoir to the pumping section is brought about under the influence of another force other than the pumping force, for example, under the influence of gravity.

A pump unit (4) comprises a reservoir (20) for containing a liquid, a duct system (30) for conveying the liquid and a pumping section (50) for subjecting the liquid to a pumping force. Initially, in a pump unit according to the state of the art, the duct system is filled with air. This causes problems at the start of the operation of the pump unit, or, in case the applied pumping force is high enough to prevent such problems, this leads to a flow rate of the liquid that is too high. This problem is solved by bringing about an initial filling of at least a portion of a duct (31) for conveying the liquid from the reservoir (20) to the pumping section (50), under the influence of another force than a pumping force, for example under the influence of gravity.
摘要:
A system for preparing a beverage comprises a beverage maker (15) and a cartridge (10) that is removably arranged in the beverage maker (15). The cartridge (10) comprises a beverage making unit (1) having a duct system (30) for conveying flows of steam and flows of liquid. The duct system (30) comprises two combinations of ducts (31, 32; 41, 42), wherein the arrangement of the ducts (31, 32; 41, 42) of each combination is adapted to enabling a flow of steam to perform a pumping action on a flow of liquid. The beverage maker (15) comprises a steam generator (16) having two steam sockets (17, 18), wherein each of the steam sockets (17, 18) is in communication with another combination of ducts (31, 32; 41, 42) of the duct system (30). As each of the combinations of ducts (31, 32; 41, 42) is associated with a different steam inlet (36, 46), and the steam inlets (36, 46) may be located at different positions on the cartridge (10), it is achieved that the duct system (30) may be of a relatively simple design.
摘要:
A disposable cartridge (10), which is suitable for use in a process of preparing a beverage, comprises a pump unit (1). A duct system (30) of the pump unit (1) has a first duct (31) and a second duct (32) which merges into the first duct (31), wherein an angle (θ) between the ducts (31, 32) is considerably smaller than 90°. In a process of preparing a beverage, a first fluid is supplied by an inlet portion of the first duct (31), and a flow of a second fluid is supplied by the second duct (32). At the position where the ducts (31, 32) meet; a transfer of momentum from the flow of the second fluid to the first fluid takes place, so that an underpressure is obtained, as a result of which the first fluid is put in motion. Furthermore, a joint flow of the first fluid and the second fluid is obtained in an outlet portion of the first duct (31).

摘要:
A frothing device (1) is disclosed which is suited for a beverage machine. The frothing unit has an inlet (11) for a frothing medium (12) and a gas inlet (13) with an opening diameter. Furthermore, the frothing unit comprises a pumping means (14) and a tubing (15) for connecting the aforementioned components to one another. The aforementioned components form a continuous tubing system. In addition, due to the pumping action of the pumping means, a negative pressure difference with respect to the atmospheric pressure is accomplished throughout the whole tubing system.

摘要:
A device for performing a process of treating a liquid such as milk during which air is supplied to the liquid comprises a detachably arranged liquid treating unit and a basic part (3) which is suitable for receiving and accommodating the liquid treating unit. The liquid treating unit has an air restriction for taking in air to be used in the liquid treating processes, wherein the air restriction comprises a pin (11) and a hole for receiving the pin (11). In particular, the pin (11) is rotatably arranged in the hole, wherein means (15, 16, 17) are provided for causing a rotation of the pin (11) in case of a movement of the liquid treating unit in and/or out of the liquid treating device. In this way, an automated pin rotation mechanism is realized, whereby any blockage of the air restriction may be destroyed, and a reliable functioning of the air restriction is ensured.
