## Abstract

The disclosure includes a method of using a biomass extraction and centrifugation system to extract and centrifuge biomass. In some embodiments, the method comprises loading a first portion of biomass into a vessel and loading a first portion of solvent into the vessel, and holding the first portion of biomass and the first portion of solvent in the vessel for a predetermined amount of time, whereby the first portion of biomass and the first portion of solvent define a first slurry of a first cycle. Accordingly, in some embodiments, the method comprises extracting at least a portion of a biomass extraction from the first slurry, and separating, via a centrifuge, the first slurry into a first extract discharge and a first waste discharge.

## Claims

### Claim 1

A method of using a biomass extraction and centrifugation system to extract and centrifuge biomass, the method comprising:
sending a first portion of biomass from a biomass feed tank into a vessel and sending a first portion of solvent from a solvent feed tank into the vessel;
holding the first portion of biomass and the first portion of solvent in the vessel for a predetermined amount of time, wherein a first slurry of a first cycle comprises the first portion of biomass and the first portion of solvent;
extracting at least a portion of a biomass extraction from the first slurry of the first cycle;
separating, via a centrifuge fluidly coupled to the vessel, the first slurry of the first cycle into a first extract discharge and a first waste discharge;
sending a second portion of biomass from the biomass feed tank into the vessel and sending a second portion of solvent from the solvent feed tank into the vessel;
holding the second portion of biomass and the second portion of solvent in the vessel for the predetermined amount of time, wherein a first slurry of a second cycle comprises the second portion of biomass and the second portion of solvent;
extracting at least a portion of a biomass extraction from the first slurry of the second cycle;
separating, via the centrifuge, the first slurry of the second cycle into a second extract discharge and a second waste discharge; and
separating the first slurry of the first cycle while simultaneously sending the second portion of biomass and the second portion of solvent into the vessel for the second cycle.

### Claim 2 (depends on 1)

The method of claim 1, wherein the sending, extracting, and separating steps repeat until at least one of the biomass and solvent feed tank is substantially empty.

### Claim 3 (depends on 1)

The method of claim 1, wherein the biomass extraction and centrifugation system is sized and configured to run in a continuous manner with a constant and repeatable extraction result.

### Claim 4 (depends on 1)

The method of claim 1, wherein the vessel is fluidly coupled to at least one of the biomass feed tank and the solvent feed tank.

### Claim 5 (depends on 1)

The method of claim 1, further comprising covering the vessel to at least partially enclose the vessel.

### Claim 6 (depends on 1)

The method of claim 1, further comprising insulating, via at least one jacket, the vessel.

### Claim 7 (depends on 1)

The method of claim 1, wherein the biomass comprises cannabis and hemp.

### Claim 8 (depends on 1)

The method of claim 1, wherein the biomass comprises at least one of cannabis and hemp.

### Claim 9 (depends on 1)

The method of claim 1, wherein the biomass extraction comprises cannabidiol.

### Claim 10 (depends on 1)

The method of claim 1, wherein the solvent comprises ethanol.

### Claim 11 (depends on 1)

The method of claim 1, wherein the biomass is dried.

### Claim 12 (depends on 1)

The method of claim 1, wherein the biomass is frozen.

### Claim 13 (depends on 1)

The method of claim 1, wherein the biomass defines a form that is at least one of whole and ground.

### Claim 14 (depends on 1)

The method of claim 1, wherein the first extract discharge comprises a crude oil including cannabidiol and ethanol.

### Claim 15 (depends on 1)

The method of claim 1, wherein the biomass comprises hops.

### Claim 16 (depends on 15)

The method of claim 15, wherein the biomass defines at least one of a whole leaf and a pellet form.

### Claim 17 (depends on 1)

The method of claim 1, further comprising insulating, via at least one jacket, the biomass feed tank.

### Claim 18 (depends on 1)

The method of claim 1, further comprising insulating, via at least one jacket, the solvent feed tank.

### Claim 19 (depends on 1)

The method of claim 1, further comprising insulating, via at least one jacket, the centrifuge.

### Claim 20 (depends on 1)

The method of claim 1, wherein the biomass extraction comprises tetrahydrocannabinol.
