SYSTEM, METHOD, AND APPARATUS FOR REGULATING FLOW RATE IN AN ESPRESSO MACHINE

摘要

Embodiments are directed towards regulating flow rate in an espresso machine, during a multi-phase brewing process which includes a pre-brew and an extraction phase. During the pre-brew phase, coffee grounds are slowly pre-wetted and/or out-gassed with a first volume of water delivered at a first flow rate. During the extraction phase, a second volume of water is delivered, at a second flow rate, to extract espresso, where the second volume is delivered at a generally greater pressure than the first volume. The second flow rate is greater than the first flow rate. The flow rates, volumes, and pressures are regulated by the espresso machine, which includes a flow rate regulation assembly that comprises first and second flow paths and first and second valves. Baristas may vary the flow rate, volume, and pressure of water throughout the brewing process by opening, closing, or otherwise adjusting at least one of the valves.

主权项

1. A flow rate regulating system configured and arranged for adjusting a brewing fluid flow rate while brewing a beverage from the flowing fluid, the system comprising:
an input aperture; an output aperture, wherein the brewing fluid flow rate is an output fluid flow rate of the output aperture; a first fluid-flow path that is in fluid communication with the input aperture and the output aperture; a pump configured and arranged to pump fluid from the input aperture, through the first fluid-flow path, and out of the output aperture; a brew tank configured and arranged for heating fluid flowing in the input aperture and out the output aperture; and a first valve that is configured and arranged to adjust a first fluid flow rate through the first fluid-flow path, wherein, the brewing fluid flow rate includes at least the first fluid flow rate through the first fluid-flow path.
