The spinning band distillation column has a vacuum jacket (like a thermos) to minimize heat loss through the distillation column wall. The evacuated jacket disrupts heat conduction due to the lack of air (only 10-7 mmHg !). The vacuum jacket has a silver coating on the inside to reflect any radiant heat. Combined with the […]
Spinning band distillation can produce distillate with very high THC/CBD concentrations. Over 90% THC concentration is typical for a first pass. Some customers are routinely producing 98%+ cannabinoid distillates! How does the spinning band do it? Distillation separates components by their boiling points. This is commonly referred to as the “efficiency” of a distillation […]
Decarboxylation, AKA Decarbing, is the process of spontaneously converting THC-A to THC with heat (approximately 80-90 C). During decarbing THC-A is converted to THC when the carboxylic acid group on THC-A is removed liberating a CO2 molecule leaving THC behind. Decarbing is important because THC-A is not psychoactive, but THC is. Other cannabinoids like CBD […]
Spinning band can distill THC, CBD, and other cannabinoids at greatly reduced temperatures. The distillation rate also prevents material from staying at temperature for extended periods of time. Above certain temperatures or after many hours of being hot, isomerization can occur. Wiped film manufacturers would have you believe cannabinoids degrade easily with time exposure to […]
B/R spinning band systems are equipped with o-ring joints. O-ring joints are awesome! They make vacuum tight seals without the use of vacuum grease. Finding vacuum leaks is time consuming and frustrating. O-ring joints make such good seals that having a vacuum leak will be rare. The o-ring sits in a polished grove on the […]
Ethanol for easy and complete cannabis oil transfer Extracted oil is viscous and sticky. It requires heating in order to transfer it and valuable residue left behind in the original container. If you have ever run a rotovap, you will know the last bit of solvent always takes the longest to remove. The oil gets […]
Scalable B/R Cannabiniod distillation systems offer a selection of boiling flask sizes to fit your needs. Choose from 1, 2, 3, 5, 12 and 22 liter sizes. Boiling flasks are interchangeable. The distillation system can grow along with your company. Upgrade to larger boiling flasks or move up to a higher throughput spinning band […]
Wiped film (WF) distillation is intended to be operated as a continuous process. Continuous processes have the advantage of running nonstop. Oil is fed in one end and product comes out the other end. But wiped film for cannabis oil is being operated as a multi stage batch process which is on the other end […]
Spinning Band Distillation Fewer passes = Faster distillation + Higher Purity + Easier Cleaning Throughput for a wiped film system is slower since: 3 passes are required 3 cleaning cycles are required decarbing is a separate step oil must be stripped of ethanol before distilling final purity is less than with a spinning band system […]
