Abstract
A method of processing coffee grounds. The method includes drying coffee grounds to at least a predetermined dryness by using a rotatory drier to heat and agitate the grounds while measuring the dryness of the drying coffee. After the coffee grounds have been dried, they are mixed with supercritical CO2 to separate liquid components of the coffee grounds from solid components. This provides a simple, safe way of extracting coffee oil and producing coffee flour.
Claims20
A method of processing coffee grounds, comprising:
- drying coffee grounds to at least a predetermined dryness by using a rotatory drier to heat and agitate the coffee grounds while measuring the dryness of the drying coffee grounds;
- and
- mixing the dried coffee grounds with supercritical CO2 to extract liquid components of the coffee grounds from solid components.
An apparatus for processing coffee grounds, comprising:
- a rotary drier configured to receive coffee grounds, the rotatory drier comprising:
- a heater configured to heat the received coffee grounds;
- a rotary agitator configured to agitate the received coffee grounds;
- and
- a sensor configured to measure the dryness of the received coffee grounds during drying;
- wherein the rotary drier is configured to dry the received coffee grounds to at least a predetermined dryness;
- and
- a supercritical CO2 extraction assembly comprising:
- an extraction vessel configured to receive the dried coffee grounds from the rotary drier;
- a source of CO2;
- a heater and a pump configured to condition the CO2 received from the CO2 source to be in a supercritical state within the vessel;
- and
- an outlet for extracting liquid components of the coffee grounds from the n extraction vessel.
