1. Extracting Terpenes: What exactly is the goal?
Extracting Safely and Effectively is the goal.
Terpenes are delicate volatile compounds made up of isoprenes that need a gentle process that
can dissolve and flush them out using a liquid phase solvent with the proper loading ratio so that
you can perform a complete extraction in one pass at any speed, ad co solvents, control contact
time and temperature.
I would say that if proteins are the building blocks of life, terpenes are the building blocks
of the soul. They form steroids, activate receptor sites, control thought, impulse you name it.
Not just created in plants for humans they are also produced in insects, and even seed clouds to
provide shade to the plants that produced them. They are symbiotic in the extreme.
1.
A volatile Solvent is one that boils at very low temperatures. This allows it to be removed without
losing the volatile compounds extracted out of the plant. Almost all volatile solvents used are
flammable.
Recovery of flammable volatile solvents has to be done with distillation because it
is a flammable volatile solvent that cannot be controlled reliably with moving parts between intake
and exhaust as when a Recovery Machine is used to recover the solvent. Currently the only
recovery machine created for flammable solvents was designed to be used exclusively in the
HVAC industry because that industry is more lenient due to the environment it will be used in.
Using a Heating and Air Conditioner pump to recover solvent that is used to extract out medicine
in a lab environment is not an option and to this day there has never been a food grade
flammable volatile solvent pump rated safe for use in a lab. Hence the HVAC pumps use.
It has been used and removed in the past and it was removed for good reason yet these newbie
companies either don’t know any better or don’t care about the harm it causes.
There focus seems to be on making cheaper extractors with slower tanks requiring the use of this
pump to make them faster while raking in dollars and ignoring the consequences.
The pump process we dismissed was promoted in Colorado and later California by our past
employee who was fired for suspected arson over 10 years ago. It has taken a foot hold around
the country which makes it our mission to educate the public to prevent that mistake we suffered
from in 2004 from developing any further in the rest of the country.
After that fire we created a pump free process that is as fast as any pump and can be faster or
slower with simple effective adjustments that do not inhibit the other extraction parameters in any
way.
As a matter of fact it is the removal of the pump that allows them.
You can turn on or off or adjust to any functional degree, heat, time and polarity while remaining
in liquid phase. The only controllable parameters are material quality, density of material, solvent,
density, contact time, contact temperature, polarity and pressure and pressure has the least
positive effect. Excessive pressure actually creates more problems than it solves.
You need to hang on to those controls. Do not give them up for upfront savings or solvent
recovery speed.
How are these pumps being allowed?
States currently use fire inspectors to give the ok in a lab room. They view the safety rating for a
air conditioner pump that allows its use for recovering R600 or R600A. Fire Departments are
concerned with Fire prevention, not health codes. When a HVAC pump boast a safety rating in
the HVAC industry it is thought that it can be used safely to recover solvent used in a lab
environment.
Fire inspectors rightfully point out, mandating health regulations should be performed by a
different dept.
In the case of isobutane and butane, R600 and R600A are commonly used or mistaken for
butane and isobutane.
Refrigerants used in a AC pump may not be created using the same techniques as when labeled
and used as Butane and Isobutane Solvents used to extract consumables. Until recently this was
not a problem because butane was not commonly being used as a solvent. but it is now a
problem that should be researched. Until this issue is resolved only Butane and Isobutane should
be allowed for making consumables. Not R600 (HVAC Butane) or R600A (HVAC Isobutane).

2. This is a epidemic problem that will hurt the entire industry if not dealt with properly and fire
inspectors should not be the ones burdened with the problem.
I should add if a safe food rated pump is ever created for use in a lab to make consumables I will
be putting them on my machines but for recovery only.
We have super fast tanks that run fine without artificial means. When you use a pump on a fast
tank they evaporate even faster if fast recovery is what you want but they serve no purpose
during extracting and they create nothing but problems and limitations.
This statement comes from 20 years of research in a properly permitted lab in Texas extracting
from all plants using various types of extraction equipment.
In addition to the problems of pumps, when a proper load ratio and proper cleaning processes
are not used valuable compounds are removed from the final product.
This brings up the fad problem of choosing medicine based on texture and color. A simple
problem that can be overcome by requiring an analysis to be supplied showing the contents of
the product to the consumer.
These extractor manufacturers and retailers are so focused on confusion they simply don’t know
where the bullseye is. I have seen products chosen over superior products by retailers simply
because they are easier to package.
There needs to be a complete workup of all compounds in the plant including all the physical
properties of each compound. The intended use is not even addressed relative to the analytical
report. Only then will one know what they are doing, why they are doing it and how to do it again.
You need an extraction apparatus that can repeat that process again without destroying or losing
your product during extraction and during solvent recovery or refinement. This is done by
separating the extraction process from the recovery process and using up to date isolation
equipment such as centrifuge machines, cold traps, separatory funnels, filtration, condensers and
so on.
States also need to allow the extracted compounds to be reconstituted back into additional
solvents so those molecules can freely move and be separated further using the centrifuge
machines, separatory funnels, condensers and so on.
Eliminating the ability to dissolve the extract into solvent after the extraction solvent is removed
defeats the whole purpose of extracting from the plant matter. Yet I have learned this is exactly
what Colorado has done.
Until SCFE super critical fluid extractors using CO2 came around we only had heated systems
which wreaked havoc on delicate molecules during extraction. The heat created a plethora of
problems while adding extreme lipid content that had to be removed from the extract.
Most of the sought after compounds were lost while removing the solvent after extraction due to
the solvents higher boiling temperatures over CO2
As a matter of fact some of those compounds were completely missed and never identified
even with CO2 because the plant matter had to be bone dried or CO2 would react with the
water molecules producing carbonic acid. So they were evaporated into the atmosphere
and never seen.
Now we have another more economical, viable, controllable option that is faster, safer,
easier to operate and less reactive than CO2 due to the lower pressure and lower operating
temperature. That solvent of choice is N Butane. N for Normal.
Butane is the safest non polar volatile solvent available when used in a properly designed
system operating with a safe distillation process to recover the solvent.
Why? Because it can be recovered without the aid of electrically powered reciprocating engines
(HVAC) that will inherently fail.
So by removing the engine we gain safety, control and repeatability.
Now why would you add it in the first place. They add it to cut cost on tank design.
Smaller diameter slower evaporating tanks are exponentially cheaper to build. The cost
of the pump is passed on to the end operator and will never be amortized out by the user.
By understanding all these requirements regarding safety, standardization, repeatability and
control from day one (+15yrs ago) we created a apparatus that envelopes all those concepts.
I did not create a process that evolved into being able to do all this. All this was the goal.

3. I can make any extractor and sell it. I own the prior art on all the flammable volatile solvent
extractors being sold today. I choose the tamisium design over the others due to the safety and
effectiveness.
CO2 is second choice due to the dangers of high pressure, expense, limitations and
ineffectiveness.
It is this fact of effectiveness, expense, quality that forces people to gravitate to the other choices.
It is a compelling force and the summary is in my opinion the best way to deal with it.
