Let’s check out how the short path wiped film Rotary Evaporators works. Where other methods employ solvents to assist the extract material move or flow with the process, these systems take advantage of the melting points of cannabinoids instead.
These compact systems are set with a feed vessel sending extract material in to a heated evaporation vessel. Inside this evaporation vessel is actually a rotating wiper blade that evenly distributes the extract material onto the vessel walls. The extract material only spends a short length of time on the wall to limit heat exposure and then any degradation to the material.
The close proximity of the condenser towards the heated vessel wall provides a short path for the extract to go to. Hence the name, short path distillation process. Since the wiper system moves the extraction material down through the vessel, it evaporates to the condenser which converts it back to your liquid. This liquid will be collected at the bottom and is also now a distillate.
Heavier material like the chlorophyll, sugars, salts, and wax fractions are unable to evaporate off the top of the evaporation vessel wall and in addition they travel, through the wiper blades, right into a separate container that is also in the bottom. Another and chilled evaporator captures the terpenes in their own flask.
The Short Path Distillation Process – The Short Path Distillation employs a setup that uses exactly the same principles, just without the wiper system to distribute the extraction material.
Instead, a heated flask is when the extraction material is fed. Gradually, increased heat is used to the extract material in the feed flask. A vacuum can also be applied to assist in drawing the vapors up into the fractionating tubing. Through the fractionating tubing the contents then hit the condensing tube, in which the fractions take separate paths.
Just like the wiped film process, the load of each fraction determines the collection flask.
To improve product refinement, each process can hold the extract material run through them multiple times. Like the wiped film process, this setup is additionally relatively compact and lends well to multiple devices working simultaneously in a smaller space.
Benefits associated with Short Path Distillation – Flavor and “experience” are clearly more consumer-centered advantages, but also for producers, there are lots of more that are included with employing either a short path distillation process or short path wiped film distillation process.
One production advantage is something called “continuous feed” which is great for making large amounts of product for longer periods of time with greater consistency.
Where other extraction processes use heated beakers, continuous feed also enables a greater amount of scalability to your production which just isn’t a lot of an option with batch mode stills.
High evaporation rates enable more distillates to get captured as the relatively low processing temperatures (130-180°C) play a role in the truth that there aren’t any solvents necessary to move the extract material from the process.
Most significantly, this technique will separate cannabis into high concentrations of THC and CBD distillates. In reality, short path distillation can bring about cannabis distillates which can be 99% pure. If you are attempting to make a pure CBD product, for example, going with the short path distillation process is probably the best methods you can use.
The compact style of short path distillation systems makes them an excellent option to use in operations where large quantities of multiple strains have to be extracted. Lastly, these machines are easy to use and therefore are largely automated within their function.
Isolate versus Full-Spectrum – Making use of the short path distillation or wiped film distillation process leads to pure isolates – whether that be THC, CBD, or any other cannabinoid or terpene you may be deciding to distill.
Isolates are the purest and many potent kind of the compound, and they also possess some benefits like being completely odorless and tasteless. This really is great if you use these compounds in foods or beverages, for example, as it will not alter the taste in any respect.
However, a developing body of scientific studies have found that full-spectrum extracts have several benefits over isolates. The number of compounds found in cannabis work together to form what’s referred to as entourage effect, which enhances the effectiveness of the medicinal properties.
As a result, you may want to accept the pure isolates produced from the short path distillation process and use reverse chromatography methods that will result in a full-spectrum extract. This can be especially useful uuubfc creating very effective CBD products, for instance, since the end product can still have no traces of THC, but will still have many of the other beneficial compounds found in cannabis.
The wonder with using Molecular Distillation is that you simply can isolate each specific compound, then combine them together in unique blends that can yield highly specific results. The options are endless if you use technology as precise as short path distillation.
