Cannabis Distillation FAQ
What is a Short Path Distillation Unit?
A short path distillation unit consists of a short path evaporator combined with a wiped film evaporator with an internal condenser in a single apparatus. A wiping system spreads the feed material onto the heated internal evaporator surface just like in a wiped film evaporator. Unlike in a wiped film evaporator, in a short path evaporator the vapors are condensed on a condenser located inside the evaporator. The distance between the heated surface and the condenser surface is very short, hence the term Short Path.
What is Wiped Film Distillation?
A rotating wiper system distributes the crude product to a film on the inner surface of a heated pipe. The wiping system speeds up the evaporation process by keeping the product film turbulent so that the heat transfer and mass transfer are optimised. The lower boiling fraction of the raw material evaporates out of the product film within a short time; the residence time of the product at the evaporator wall is very short. The vapours are condensed on an external condenser. The concentrate is continuously discharged out of the bottom part of the evaporator. The processing of viscous or crystallising substances at pressures down to 1 mbar is possible.
Who is VTA?
What is BHO extraction?
Butane Hash Oil, or BHO is the essential oil extracted from the cannabis plant using Butane as a solvent. BHO extraction can be extracted from fresh or cured material. The result is a mix of concrete oils, waxes, cannabinoids and terpenes. Our cannabis distillation equipment can be viewed here with a video demo.
What is the throughput per hour on your wiped film evaporator?
The Short Path Distillation Plant VKL 70-5 has a throughput of 1700ml per hour for cannabis distillation using winterized BHO (Butane Hash Oil) or winterized CO2 oil.
Is it a continuous feed system?
Yes! Our wiped film evaporator, specifically the Short Path Distillation Plant VKL 70-5 is a continuous feed system since the feed tank is not under vacuum.
Is your Short Path Distillation setup fully jacketed?
Yes, our wiped film evaporator is fully jacketed to help maintain a consistent temperature throught the cannabis distillation process.
What is included with your Short Path Distillation equipment?
Root Sciences provides a commercial-scale solution for cannabis distillation. We provide full machine assembly, testing and training to allow you to produce distillate on day one using our wiped film evaporator!
