Why United Bio Freeze switched from traditional drying methods to flash freezing their hemp harvest

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.
