## Abstract

A shallow bed solvent extractor comprises at least one moving bed having upstream and downstream ends and a feed inlet positioned adjacent to the upstream end, wherein a first batch of wet cannabinoid and terpene containing material is introducible to the at least one moving bed through the feed inlet. An outlet is positioned adjacent to the downstream end, wherein the first batch of wet cannabinoid and terpene containing material is carried on the at least one moving bed and exits the extractor through the outlet. A drive system is operatively connected to the at least one moving bed. The shallow bed solvent extractor further comprises a plurality of sprayers disposed above the upstream and downstream ends of the at least one moving bed and a non-polar solvent. The plurality of sprayers spray the first batch of wet cannabinoid and terpene containing material with the non-polar solvent.

## Claims

### Claim 1

A shallow bed solvent extractor comprising:
at least one moving bed having upstream and downstream ends;
a feed inlet positioned adjacent to the upstream end, wherein a first batch of wet cannabinoid and terpene containing material is introducible to the at least one moving bed through the feed inlet;
an outlet positioned adjacent to the downstream end, wherein the first batch of wet cannabinoid and terpene containing material is carried on the at least one moving bed and exits the extractor through the outlet; and
a drive system operatively connected to the at least one moving bed;
a plurality of sprayers disposed above the upstream and downstream ends of the at least one moving bed; and
a terpene solvent; wherein
the plurality of sprayers spray the first batch of wet cannabinoid and terpene containing material with the terpene solvent; and wherein
the shallow bed extractor further comprises:
a pressing mechanism operationally disposed downstream of the outlet, wherein the wet cannabinoid and terpene containing material exits the extractor through the outlet and is introduced into the pressing mechanism, and the pressing mechanism is configured to compress the wet cannabinoid and terpene containing material and to squeeze out a mixture of one or more terpenes, water, and other organic matter from the wet cannabinoid and terpene containing material; and
a collection vessel connected directly to the pressing mechanism and configured to collect the squeezed out mixture of one or more terpenes, water, and other organic matter, wherein the collection vessel is further configured to allow the squeezed out mixture of one or more terpenes, water, and other organic matter to stand until the squeezed out one or more terpenes separates out of the mixture; and wherein
at least a portion of the terpene solvent comprises the squeezed out one or more terpenes separated out of the mixture.

### Claim 2 (depends on 1)

The shallow bed solvent extractor of claim 1, wherein the terpene solvent is selected from the group of terpenes consisting of d′limonene, Myrcene, Linalool, Caryophyllene, Alpha-pinene, Beta-pinene, Humulene, and combinations thereof.

### Claim 3 (depends on 1)

The shallow bed solvent extractor of claim 1, wherein at least a portion of the terpene solvent is extracted from a second batch of wet cannabinoid and terpene containing material introduced into the shallow bed solvent extractor prior to the introduction of the first batch.

### Claim 4 (depends on 1)

The shallow bed solvent extractor of claim 1, wherein the at least one moving bed comprises two oppositely moving beds operationally connected between the downstream end of the first moving bed and the upstream end of the second moving bed.

### Claim 5 (depends on 1)

The shallow bed solvent extractor of claim 1, wherein the pressing mechanism is selected from the group of pressing mechanisms consisting of a screw press, a jacketed screw press, and a sludge press.

### Claim 6

A method for using a shallow bed solvent extractor, comprising the steps of:
providing a shallow bed solvent extractor comprising:
at least one moving bed having upstream and downstream ends;
a feed inlet positioned adjacent to the upstream end;
an outlet positioned adjacent to the downstream end;
a terpene solvent;
a drive system operatively connected to the at least one moving bed; and
a plurality of sprayers disposed above the upstream and downstream ends of the at least one moving bed;
introducing a first batch of wet cannabinoid and terpene containing material into the at least one moving bed through the feed inlet;
carrying the first batch of wet cannabinoid and terpene containing material on the at least one moving bed;
washing the first batch of wet cannabinoid and terpene containing material being carried on the at least one moving bed with the terpene solvent sprayed through the plurality of sprayers;
providing a pressing mechanism operationally disposed downstream of the outlet:
allowing the wet cannabinoid and terpene containing material to exit the extractor through the outlet;
introducing the wet cannabinoid and terpene containing material into the pressing mechanism;
compressing the wet cannabinoid and terpene containing material within the pressing mechanism to squeeze out a mixture of one or more terpenes, water, and other organic matter from the wet cannabinoid and terpene containing material;
collecting the mixture of one or more terpenes, water, and other organic matter;
allowing the mixture of one or more terpenes, water, and other organic matter to stand until the one or more terpenes separates out of the mixture; and
collecting the one or more terpenes and using the one or more collected terpenes as part of the terpene solvent in the washing step.

### Claim 7 (depends on 6)

The method for using a shallow bed solvent extractor of claim 6, wherein at least a portion of the terpene solvent is extracted from a second batch of wet cannabinoid and terpene containing material introduced into the shallow bed solvent extractor prior to the introduction of the first batch.

### Claim 8 (depends on 6)

The method for using a shallow bed solvent extractor of claim 6,
wherein the mixture of one or more terpenes, water, and other organic matter is allowed, to stand for between about 0.1 hour and about 100 hours at between about 5° C. and about 90° C., and between about 0.1 bar pressure and about 5 bar pressure until the one or more terpenes separates out of the mixture.

### Claim 9 (depends on 6)

The method for using a shallow bed solvent extractor of claim 6, wherein the terpene solvent is selected from the group of terpenes consisting of d′limonene, Myrcene, Linalool, Caryophyllene, Alpha-pinene, Beta-pinene, Humulene, and combinations thereof.
