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 growing, harvesting, processing, extraction and packaging. Air Products has been successfully supplying industrial gases to the food and pharmaceutical industries for over 60 years. Now, we're applying our expertise to support hemp producers as well.

How We Can Help
Our team of experts can review your process and help you identify opportunities where liquid nitrogen or CO2 can enhance product quality and shelf-life, increase productivity, and improve safety. We have a state-of-the-art applications lab to test your product, or we can visit your site for field testing.Harvesting
Flash freezing freshly harvest hemp with liquid nitrogen in an Air Products Freshline IQ tunnel freezer can help prevent biomass degradation or mold while locking in the plant's rich chemical content.
Processing
During the biomass material preparation process, adding liquid nitrogen to the mill when grinding can eliminate heat and subsequent oil stickiness that causes clogging and downtime. Pre-cooling biomass prior to entering extraction using a PolarFit® screw conveyor provides the ultimate means of temperature control.
Extraction
Whether it be super critical CO2 or ethanol extraction, we have your needs covered. For ethanol extraction, the ultracold properties of liquid nitrogen can be used to achieve and maintain temperatures in the less than -80⁰C range as a more cost effective and efficient means for more precise extraction. For supercritical CO2 extraction, we can safely and reliably provide CO2 supply systems at your facility.
Packaging
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. Read more about Modified Atmosphere Packaging, or MAP.
Inerting
When working with flammable materials or to keep CBD product fresh, using a nitrogen blanketing system is a paramount best practice for safety and to achieve high-quality product. Keeping oils free from moisture and oxygen via nitrogen blanketing can also help extend shelf-life.
