The present invention presents a pumping system (1) with a preheated reservoir (2), a main pump (4) for pumping a preheated liquid (3) from the reservoir (2), and pressurizing means (5) for pressurizing the reservoir (2). Preferably, the pressurizing means set an absolute pressure of 0.5 to 1 bar in the reservoir (2). The liquid (3) in the reservoir (2) can be heated up to 90 C. or more. The present invention achieves a nearly complete suppression of the phenomenon of cavitation at the main pump entrance, and thus achieves an increased pumping performance at elevated liquid temperatures.

Systems and methods operable to brew and then cool a beverage include inserting a pod into a recess of a machine for providing the beverage, the pod comprising granulated ingredients and a filter, displacing a cap of the pod, by a plunger, into the pod; the plunger being used to compress the graduated ingredients and the filter, heating water within the machine using a refrigeration system of the machine, flowing the heated water through the compressed granulated ingredients and through the filter of the pod to brew a brewed beverage; and dispensing the brewed beverage from the pod.

An infused beverage brewing assembly having a solvent flow management system (SFMS) operably configured to receive a solvent and induce a flow of the solvent through a first solvent conduit and a second solvent conduit, a solvent temperature modulation system (STMS) operably configured to thermally modulate a solvent within the first solvent conduit to join with a solvent in the second solvent conduit to form a resulting solvent conduit with a resulting solvent. The assembly has a brewing chamber in fluid communication with the resulting solvent conduit and for housing a solute disposed to receive the resulting solvent to produce an infused beverage, an outlet for discharging the infused beverage, and a resulting solvent valve operably configured to select a path of the resulting solvent until reaching a desired temperature, thereby enabling resulting solvent delivered to the brewing chamber at a desired temperature.

The beverage producing machine comprises a brewing chamber and at least one hydraulic actuator for controlling closing and opening movement of the chamber. A water pump, fluidly connected to the chamber through a first water path and fluidly connected to the actuator through a second water path delivers pressurized water to the chamber and actuator, respectively. A water heater and a first valve arrangement are arranged along the first water path. A second valve arrangement is positioned along the second water path, between the water pump and the actuator. The first and second valve arrangements are configured and controlled such that during a brewing chamber closure step the first valve arrangement is closed, and the second valve arrangement is open. Upon reaching a closure pressure in the actuator, the second valve arrangement is closed and the first valve arrangement is opened, allowing water to be delivered to the chamber.
