Abstract
A coffee brewing system and method brew hot coffee at an elevated temperature by mixing coffee grounds with hot water, filtering the hot coffee to remove at least some of the coffee grounds from the hot coffee to form filtered hot coffee, and rapidly cooling the filtered hot coffee to reduce a temperature of the filtered hot coffee to form cooled coffee. The coffee optionally may be mixed with a gas, such as nitrogen, prior to serving the cooled coffee. The system and method can rapidly produce cold coffee in large amounts without diluting the coffee in water or ice, or waiting for the coffee to cool in a refrigerated environment.
Claims20
A system comprising:
- a brewing tank configured to receive coffee grounds and water, the coffee grounds mixed with the water at an elevated temperature to brew hot coffee in the brewing tank;
- one or more filters configured to filter the hot coffee to remove at least some of the coffee grounds from the hot coffee to form filtered hot coffee;
- a heat exchanger configured to rapidly cool the filtered hot coffee without diluting the filtered hot coffee to reduce a temperature of the filtered hot coffee by at least one hundred forty degrees within five minutes to form cooled coffee;
- and
- one or more conduits fluidly coupling the brewing tank and the heat exchanger.
A method comprising:
- brewing hot coffee at an elevated temperature by mixing coffee grounds with hot water in a brewing tank;
- filtering the hot coffee to remove at least some of the coffee grounds from the hot coffee to form filtered hot coffee;
- and
- rapidly cooling the filtered hot coffee without diluting the filtered hot coffee to reduce a temperature of the filtered hot coffee by at least one hundred forty degrees within five minutes to form cooled coffee.
A system comprising:
- a brewing tank configured to receive coffee grounds and hot water, the coffee grounds mixed with the hot water at an elevated temperature to brew hot coffee;
- and
- a heat exchanger configured to rapidly cool the filtered hot coffee from a temperature of at least 180 degrees Fahrenheit to forty degrees or less within twenty minutes.
