Beverage extracting device

A beverage extracting device comprising:

• a vessel for receiving and mixing a powder material and hot liquid;
• a filter beneath the vessel;
• an electrical gas pump that connects through a duct to the vessel for supplying pressurized gas into the vessel;
• and
• an outlet for extracted liquid at an outlet side of the filter which is opposite to the vessel,
• wherein the outlet connects to an outlet duct for the extracted liquid, and
• wherein a current sensing circuit connects to a power line of the electrical gas pump for monitoring an electrical current through the electrical gas pump, and
• wherein the current sensing circuit is directly or indirectly connected to a controller for detecting whether the electrical current is above a preestablished threshold, and
• wherein the controller is arranged to reduce power supplied to the electrical gas pump when the controller establishes that the electrical current through the electrical gas pump is above the preestablished threshold.
