FreeZenTrees delivers industrial LN₂ cryogenic freezing directly to your farm or processing facility. Our tunnel system freezes biomass within minutes of harvest, locking in trichomes, preventing oxidation, and producing premium extraction-ready material with unmatched consistency.
To deliver scientifically engineered cryogenic preservation that protects the full chemical and structural integrity of cannabis flower from the moment of harvest.
Flash freezing is not simply “getting it cold.” It is controlling the crystal formation process. LN₂ vapor forms microscopic ice crystals that protect cell walls and trichomes — something conventional freezers cannot do.
FreeZenTrees was created to solve one of the biggest challenges in the cannabis industry: quality loss between harvest and extraction. Conventional freezers take hours to freeze biomass, causing oxidation, terpene loss, color degradation, and trichome damage.
Our founder, Steve, an engineer with decades of experience in cryogenic and industrial freezing systems, designed a mobile LN₂ tunnel that preserves flower with food-grade IQF (Individually Quick Frozen) precision.
The result is a scalable, field-ready flash-freezing solution that produces premium fresh-frozen material trusted by processors, extractors, and brands demanding absolute quality.
Our system uses liquid nitrogen vapor to rapidly and uniformly cool flower to sub-zero temperatures within minutes. Unlike slow mechanical freezers, LN₂ freezing prevents oxidation and preserves terpene-rich volatile compounds.
1–5 minutes
Nitrogen vapor — no direct LN₂ contact
Up to 12,000 lbs/day
Minimal — preserves structural integrity
Conventional freezer (0°F to –20°F) takes 4–8 hours to freeze biomass. Slow freezing forms large ice crystals that rupture plant cells and damage trichomes.
Standard Freezer: 4–8 hours
LN₂ Tunnel: 1–5 minutes
Standard: Large, damaging
LN₂: Microscopic, protective
Standard: High risk of rupture
LN₂: Fully intact
Standard: 60–70%
LN₂: 90–95%
Standard: Varies by freezer
LN₂: Uniform, repeatable
Our mobile LN₂ tunnel freezes biomass in 1–5 minutes, preserving its full structural and chemical profile. Ideal for live resin, rosin, and premium extract inputs.
