Freeze. Grind. Extract.
Liquid nitrogen or CO2 can improve hemp-CBD quality and yield.

In the fast-growing industrial hemp market, industrial gases can play an important role in harvesting, processing, extraction and packaging. 

hempHarvesting–Flash freezing the hemp harvest with liquid nitrogen prior to storage in an Air Products Freshline® IQ tunnel freezer can prevent mold and lock in the plant’s rich chemical content

Processing–During the grinding process, adding liquid nitrogen to the mill or conveyor can eliminate heat and subsequent oil stickiness that causes clogging and downtime. 

Extraction–When cold extracting, CO2 or liquid nitrogen can be more cost effective and efficient in removing the desired oils by lessening downstream purification needed to achieve desired product quality. 

Packaging (Modified Atmosphere Packaging, MAP)–Dosing the final package with a small amount of liquid nitrogen can serve as a protective layer from oxidation or moisture effectively blanketing the oils enhancing quality and shelf-life.
