Vacuum oven purging removes residual butane, propane, or ethanol from cannabis concentrates by holding material at 100 to 115°F (38 to 46°C) under full vacuum at -29.5 inHg for 24 to 72 hours. BHO concentrates spread to 1 to 2 mm film thickness at 100°F reach compliant residual solvent levels (below 5,000 ppm total hydrocarbons [...]
Wiped film distillation purifies cannabis crude oil to 90-95% total cannabinoids by spreading a sub-1mm film across a heated cylinder at 160-180°C under sub-100-micron vacuum. Residence time is 1-3 minutes (vs 10-60 minutes in short path), reducing thermal CBN formation from 4% to under 0.5%. A 2-inch Pope system processes 500-800 mL/hour at 30% rotor [...]
What Is Remediation in Cannabis Processing? When a cannabis batch fails testing, should you remediate it or destroy it? This is one of the most expensive decisions an extraction operator faces, and most people make it based on gut feeling rather than chemistry. Remediation is the process of bringing a non-compliant cannabis product back into [...]
What Is Color Remediation Chromatography? Color remediation chromatography (CRC) is a post-extraction purification technique that uses layered adsorbent media in a pressurized column to selectively remove pigments, chlorophyll, carotenoids, and other color-causing impurities from cannabis extracts. Originally adapted from the edible oil refining industry: where magnesium silicate and activated carbon have been used for decades [...]
