Let’s check out the way the short path wiped film Rotary Evaporators works. Where other methods employ solvents to aid the extract material move or flow through 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 into a heated evaporation vessel. Inside this evaporation vessel is really a rotating wiper blade that evenly distributes the extract material to the vessel walls. The extract material only spends a quick length of time on the wall to limit heat exposure and any degradation to the material.
The close proximity from the condenser towards the heated vessel wall provides a short path for the extract to go to. Hence the name, short path distillation process. As the wiper system moves the extraction material down through the vessel, it evaporates towards the condenser which converts it back to a liquid. This liquid will be collected towards the bottom and is also now a distillate.
Heavier material like the chlorophyll, sugars, salts, and wax fractions are not able to evaporate off the surface of the evaporation vessel wall and so they travel, through the wiper blades, right into a separate container which is in the bottom. A separate and chilled evaporator captures the terpenes in their own individual flask.
The Short Path Distillation Process – The Short Path Distillation employs a setup which uses exactly the same principles, just with no wiper system to distribute the extraction material.
Instead, a heated flask is where the extraction material is fed. Gradually, increased heat is applied towards the extract material inside the feed flask. A vacuum is also applied to help in drawing the vapors up into the fractionating tubing. Through the fractionating tubing the contents then hit the condensing tube, where fractions take separate paths.
Just like the wiped film process, the load of each fraction determines the collection flask.
To boost product refinement, each process can have 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 obviously more consumer-centered advantages, but for producers, there are numerous more which come with employing either a brief path distillation process or short path wiped film distillation process.
One such production advantage is a thing called “continuous feed” which is great for making large quantities of product for longer time periods with greater consistency.
Where other extraction processes use heated beakers, continuous feed also provides for a better degree of scalability in your production which just isn’t much of a choice with batch mode stills.
High evaporation rates permit more distillates to get captured while the relatively low processing temperatures (130-180°C) play a role in the reality that there aren’t any solvents required to move the extract material through the process.
Above all, this system will separate cannabis into high concentrations of THC and CBD distillates. Actually, short path distillation can result in cannabis distillates which can be 99% pure. So if you want to make a pure CBD product, for example, choosing the short path distillation process is one of the best methods you can use.
The compact style of short path distillation systems means they are an excellent decision to utilization in operations where large quantities of multiple strains must be extracted. Lastly, this equipment is user friendly and are largely automated in their function.
Isolate versus Full-Spectrum – Using the short path distillation or wiped film distillation process results in pure isolates – whether that be THC, CBD, or any other cannabinoid or terpene you may be opting to distill.
Isolates are the purest and a lot potent kind of the compound, plus they get some benefits like being completely odorless and tasteless. This really is great if you work with these compounds in foods or beverages, for example, as it does not change the taste by any means.
However, a developing body of scientific reports have found that full-spectrum extracts have several benefits over isolates. The multitude of compounds found in cannabis work together to make what’s known as the entourage effect, which enhances the effectiveness of the medicinal properties.
Because of this, you may want to take the pure isolates produced from the short path distillation process and utilize reverse chromatography methods that can result in a full-spectrum extract. This can be especially useful uuubfc creating very effective CBD products, as an example, since the end product can have no traces of THC, and definitely will have many of the other beneficial compounds found in cannabis.
The sweetness with using Molecular Distillation is that you can isolate each specific compound, then combine them together in unique blends that can yield highly specific results. The number of choices are endless when using technology as precise as short path distillation.
