Abstract

An integrated infuser/mixer pump system features a liquid inlet configured to receive a liquid drawn from a liquid source, a gas inlet configured to receive an inlet gas from a gas source, a pump and motor combination configured to received the liquid and provide pumped liquid, a gas/liquid mixture chamber configured to receive the pumped liquid and the inlet gas, and mix the liquid and the inlet gas into a gas-infused mixture, and a gas-infused mixture outlet configured to provide the gas-infused mixture; the gas inlet having a gas liquid mixing valve with a mixing orifice that has a mixing orifice size dimensioned to provide the inlet gas to the gas/liquid mixture chamber with an inlet gas volumetric flow rate in order to mix the pumped liquid and the inlet gas with a predetermined mixture ratio that depends on the mixing orifice size.

First claim

What we claim is:

1 . An integrated infuser/mixer pump system comprising:
a liquid inlet configured to receive a liquid drawn from a liquid source; a gas inlet configured to receive an inlet gas from a gas source, a pump and motor combination configured to received the liquid and provide pumped liquid; a gas/liquid mixture chamber configured to receive the pumped liquid and the inlet gas, and mix the liquid and the inlet gas into a gas-infused mixture; and a gas-infused mixture chamber outlet configured to provide the gas-infused mixture; the gas inlet having a gas liquid mixing valve with a mixing orifice that has a mixing orifice size dimensioned to provide the inlet gas to the gas/liquid mixture chamber with an inlet gas volumetric flow rate in order to mix the pumped liquid and the inlet gas with a predetermined mixture ratio that depends on the mixing orifice size.

2 . An integrated infuser/mixer pump system according to claim 1 , wherein the gas liquid mixing valve is configured inside the gas inlet and is replaceable.

3 . An integrated infuser/mixer pump system according to claim 1 , wherein the integrated infuser/mixer pump system comprises a gas inlet fitting that is coupled to the gas inlet and has the gas liquid mixing valve configured therein, the gas liquid mixing valve is replaceable within the gas inlet fitting.

4 . An integrated infuser/mixer pump system according to claim 3 , wherein the gas inlet fitting comprises a check valve configured to prevent backflow of the pumped liquid or the gas-infused mixture.

5 . An integrated infuser/mixer pump system according to claim 1 , wherein the gas-infused mixture is a beverage; the gas includes nitrogen (N2), or carbon dioxide (CO2) or an N2 and CO2 mixture; and the beverage includes an N2 infused beverage, or a CO2 infused beverage, or a blended N2 and CO2 infused beverage.

6 . An integrated infuser/mixer pump system according to claim 1 , wherein the gas-infused mixture is a beverage; the pumped liquid includes coffee, tea, milk, beer, soda, juice, water, beer, wine, or spirit; and the beverage includes a gas-infused coffee, tea, milk, beer, soda, juice, water, beer, wine or spirit beverage.

7 . An integrated infuser/mixer pump system according to claim 1 , wherein the integrated infuser/mixer pump system is an industrial system; the gas-infused mixture is a gas-infused industrial mixture having a desired ratio of the gas and liquid for an industrial process application.

8 . An integrated infuser/mixer pump system according to claim 1 , wherein the pump is configured to drawn the liquid and provide the pumped liquid at a higher pressure.

9 . An integrated infuser/mixer pump system according to claim 1 , wherein the integrated infuser/mixer pump system comprises a pressure switch configured to sense the pressure of the pumped liquid and turn off the pump if the pumped liquid exceed a sensed pressure threshold.

10 . An integrated infuser/mixer pump system according to claim 1 , wherein the integrated infuser/mixer pump system comprises an enclosure configured to house the components of the integrated infuser/mixer pump system therein.
