Abstract
User-selectable volumes of a viscous condiment such as ketchup, mustard and mayonnaise are consistently dispensed from a pressurized vessel. The vessel is pressurized using a small air pump, a cylinder of compressed gas or an external gas source. Pressure in the vessel is kept constant by sensing the pressure using a MEMS pressure transducer. Condiment flows from the pressurized vessel into a flexible tube, which passes through an electrically-actuated pinch valve. For a given pressure in the vessel, the amount of condiment to be dispensed is determined by the time that the pinch valve is open. A processor monitors the pressure, actuation of a user interface and controls operation of the air pump.
