The present invention relates to a beverage preparation system () for controlling a beverage preparation process by injection of liquid into a cartridge (), the system comprising—a pressure adjustable pump () for delivering different pressures upon varying at least one of its drive characteristics such as the speed of the pump, —a sensor () for measuring an operating parameter of the pump () such as a current absorbed by the pump, —a flow sensor () for measuring a liquid flow parameter of liquid injected into the cartridge (), —a control unit () designed to control an extraction pressure of the cartridge () by adjusting the drive characteristics of the pump () based on pre-established pressure interpolation data () depending on the measured liquid flow parameter and the measured operating parameter of the pump.

Beverage preparation machine with enhanced pump control

The present invention relates to a dispensing device () for dispensing a food product from a exchangeable multi-dose container (), the device comprising a support () for removably supporting the container (), a sealable dosing chamber () for receiving, dosing and holding a dose of food product dispensed from the container (), oxygen reducing means () designed for reducing oxygen level in the dosing chamber (), characterized in that the device further comprises at least one piston () arranged to move relatively to the support () of the device, and configured to at least partially enclose the dosing chamber () in an initial sealingly engaged position of the piston with the support (), the piston () being designed for selectively opening the container () by moving relatively to the support () and for enabling the dosing chamber () to be charged with the dose of food product in an extended and sealingly disengaged position of the piston () relative to the support ().

Multi-serve airtight coffee dispenser

The invention relates to a beverage machine () having an external housing () and a plurality of movable beverage preparation modules () that are configured to process a beverage and/or a beverage ingredient to be dispensed via at least one beverage dispensing outlet () to a user-cup or user-mug (). The housing () has a front opening (') and forms a cavity (&#x2033;) for housing the modules (). The or each movable module () is insertable as a unit into an operative position into the cavity (&#x2033;) and removable out of the cavity (&#x2033;) via the front opening (&#x2032;), such as movable along a substantially horizontal direction into and out of its operative position. The or each movable module () is insertable as a unit into the cavity (&#x2033;) into its operative position and removable out of the cavity (&#x2033;) via the front opening (&#x2032;) independently of the presence inside the cavity (&#x2033;) of any other movable beverage preparation module () in its operative position.

Beverage machines with modularity

The invention relates to a beverage machine () having an external housing () and a movable beverage preparation module () that is configured to process a beverage and/or a beverage ingredient to be dispensed. The housing () has a front opening (') and forms a cavity () for housing the module (). The module () is insertable as a unit into an operative position into the cavity () and removable as a unit out of the cavity () via the front opening (). The housing () has a cavity connector () in the cavity () and the module () has a module connector that is connected to the cavity connector () when the module () is located there against while reaching its operative position and that is disconnected from the cavity connector () when the module () is removed from the cavity (). At least one () of the connectors has a connection interface device () that is resiliently mounted to a connection base device () to enable a positioning adjustment of the interface device () when the module connector and the cavity connector () are connected together.
