"The Clear" Solventless hash from harborside

[SoulSynergySoil]

Has anyone researched the potential of using steam distillation under vacuum to produce essential oil of our highly-touted plant? Does this relate in any way to the processes used by Clear Concentrates?

Much love and blessings to one and all,

Not sure how to do steam distillation under vacuum, but we have looked at low pressure saturated steam distillation to remove the terpenes, including the diterpene cannabinoids, because they've used it for years to remove essential oils, but alas, the diterpenes are at the outer range of steam distillation, so it doesn't work well.

What might work, is a super dry steam. For instance THC boils at 157 °C (315 °F) and CBD boils at 180 °C (356 °F). You can hit that temperature with steam at 70 and 185 psi boiler pressure respectively. http://www.turnkeyips.com/assets/steam_temperature_pressure_table.pdf

So the hot steam acts as a solvent? I wish I took chemistry and physics...never too late i guess

Utmost thanks for the response, GrayWolf. Do you have any ideas on how to utilize 70-185 psi boiler pressure in a steam distillation apparatus?

Thanks again, much love & blessings,

According to my calculations, the boiling point of CBD under 29.87hg vacuum would be far below the boiling point of H2O. This is the calculator I used: http://www.trimen.pl/witek/calculators/wrzenie.html

I think one could easily create a cheap closed loop extractor with the aforementioned technology.

I thought these types of concentrates were made with a particle separation device. Highly advanced lab equipment.

Sometimes the answer is in the semantics. I would call that reduced pressure, vis a vis vacuum, but what ever you call the rose, it lowers the temperature, rather than raise it.

What is required to use the higher pressure, is a boiler capable of that pressure, and an extraction chamber with enough restriction on the outlet to the condenser, to hold that much back pressure.

We do a similar thing with CO2 and use a 150psi relief valve to release the excess pressure, while holding 150 psi back pressure.

The principle extraction method for essential oils, has been saturated steam, some done on extremely primitive equipment in the field.

Bless ya comrade! How do you equilibrate input pressure to the output relief valve pressure?

It looks like this process is tried and true with ancient roots:

Color on oil can sometimes be attributed to the hairs on the material used. Some strains are covered in brown hairs, others electric orange hairs, these sometimes leech color out into the end product.

I realize this is not a 100% scientific reason for the color differences, but I thought I would throw it out there as many people ignore the hairs and don't think about it.

I thought it was more about the trichomes.. but iuno.. I cant wait to run this purple bud. with purple trichs.. I wana see some purple oil.

You can calculate close enough to be able to tweak it, by getting a pop off valve with a CV rating (flow rate) something below your boiler capacity, and installing a pressure regulator capable of that pressure range and flow on the supply line.

Set the steam pressure slightly above the pop off pressure and watch to see if the pressure is rising or falling in the steam vessel once it pops off. Tweak the pressure regulator until is remains steady state and voile!

This pic surfaced on instagram today. Allegedly clear concentrate's latest offering. Any of you geniuses out there have any idea what this is? I'm no scientist but my money is on photoshop, but hopefully one of you can prove me wrong.

From the color, I would guess a strain like Sky Walker extracted at subzero temperatures.

SkyWalker makes an almost transparent extraction, with grey undertones like the one pictured.

Unfortunately I don't have any good pictures of it, because of a bad camera card when we made our premier run, but here is a bad picture taken of a different run on a different day, that demonstrates the point.

PS: Watch for the March issue of High Times for a picture of the batch I wasn't able to photograph myself because of camera problems. It better demonstrates the unique color and transparency.

Looks like someone blasted a bunch of Marinol caps...

Subcritical is definitely the way to go using an SCFE set up, I own Eden Labs HI-Flow System and I've found the sweet spot for killer sub-Crit extract to be 10c/60Bar 1250kg/Mass flow
