Abstract
Anti-dripping system for a beverage dispensing device (100), the device comprising a container compartment (20) where a fluid (1) is stored, an air entry (13) through which air can be provided into the device (100) and a processing compartment (10) where fluid optionally together with air is pumped and possibly foamed, the processing compartment (10) comprising a pumping element (11) for pumping fluid and possibly air and a foaming element (12) for foaming fluid and air; the pumping element (11) comprising two moveable parts with respect to each other arranged in such a way that their relative movement in a certain direction pumps fluid by suction from the container compartment (20) and optionally also air from the air entry (13) respectively into the processing compartment (10); the foaming element (12) comprising at least a movable part and a static part movable with respect to each other, said parts driving the fluid optionally together with air through a gap (123) providing a certain level of shear stress which allows mixing and/or foaming, the pumping element (11) being configured to reverse the direction of the relative movement of the moveable parts after each dispensing ope…
