Abstract

A method for drying to increase the useful life of botanicals and shorten the time to market after harvest of the botanicals. The method may include flash freezing the botanicals, at a desired optimal temperature range, soon after harvest. The method may include storing the frozen botanicals indefinitely prior to drying. The method may include drying the frozen botanicals using a lyophilizer at a desired optimal temperature and pressure.

Claims (20)

1. A method comprising:

flash freezing a Cannabis flower, having an initial volumetric dimension, to solidify moisture content within the flower;

sublimating the solidified moisture content from the flower until the flower is substantially dried while having substantially the same volumetric dimension as the initial volumetric dimension of the flower.

2. The method of claim 1 , further comprising the steps of:

converting the sublimated moisture content to liquid form, said liquid form being comprised of water and terpene oil, said terpene oil being lighter in weight than said water;

separating said terpene oil from said water; and

collecting said terpene oil.

3. The method of claim 1 , wherein the substantially dried flower is placed in an airtight container for future use.

4. The method of claim 1 , wherein the substantially dried flower is trimmed to form a residue of particles, and the trimmed particles are packaged for future use.

5. The method of claim 1 , wherein the substantially dried flower is converted into powdered form and is packaged for future use.

6. The method of claim 1 , wherein oil is extracted from the dried flower, and the extracted oil is stored in capsule form.

7. The method of claim 1 , wherein oil is extracted from the dried flower, the extracted oil is converted into pill form.

8. A method comprising:

flash freezing a Cannabis flower, having an initial volumetric dimension, to solidify moisture content within the flower;

sublimating the solidified moisture content from the flower until the flower is substantially dried while having substantially the same volumetric dimension as the initial volumetric dimension of the flower: and

converting the sublimated moisture content to liquid form, said liquid form being comprised of water and terpene oil, said terpene oil being lighter in weight than said water.

9. A method comprising:

flash freezing a Cannabis flower, having an initial volumetric dimension, to solidify moisture content within the flower;

sublimating the solidified moisture content from the flower until the flower is substantially dried while having substantially the same volumetric dimension as the initial volumetric dimension of the flower: and

separating the substantially dried flower from the sublimated moisture content, the sublimated moisture content being comprised of water and terpene oil, said terpene oil being lighter in weight than said water.
