Welcome to the Tamisium High Performance Extractor Site. Home of the first original Self Cleaning HIGH PERFORMANCE EXTRACTOR (Many in the industry call these machines CLOSED LOOP EXTRACTORS or a CLOSED LOOP EXTRACTOR)  that silently recovers and cleans the solvent used for reuse without the aid of pumps of any kind.
This is not a Closed Loop Process or Closed Loop Extractor ( as most in the industry calls this machine or knows this machine as such ) which means it does not require you to recover your solvent and loop it through the plant matter multiple times. It completes the extraction in one pass as fast as you want at any temperature with any combination of solvents.
With 20 years in the extraction business, testing and refining this process you can be sure you have the best that we have to offer. A culmination of 20 years worth of work involving and ruling out various processes while only keeping what proved safe and effective. We did not just build and sell extractors. We operated them to develop what you have in front of you.
In 2010 the Tamisium was first sold to the public. Since then countless copies making cheaper versions using off the shelf dairy parts that clamp together have sprung up. These are all our prior art and were dropped because they required the use of the very pump we removed in 2004. In the text on the site I cover the reasons why the sytem we evolved into is better and why the HVAC pumps were removed and why a safe HVAC pump will never be created.

Using specially designed costly ASME Coded, Certifiable, FAST Tanks allows the use of a very fast distillation process to recover the volatile solvents. These solvents have a lower boiling point which allows you to remove it without boiling away your extracted chemicals. These tanks are specially designed to do this at a very fast rate. They cost more to build but you can amortize out immediately. Using a tank not optimized for this requires a pump that has to be rebuilt and kept up which means you will never amortize out. The cost of the pump in a pump based system is passed on to the consumer forever with great limitations as you will learn.

Using Fast tanks and Distillation instead of a Air Conditioner Recovery Pump allows more control over the process than ever because you can immediately send the appropriate volume of solvent, in liquid phase, through the plant material in one slow or fast burst, at any temp, at any polarity without waiting for a air conditioner recovery pump to recycle the solvent to loop it back through your plant material. Being able to extract quickly avoids waxes and other lipids and prevents the need to extract at super cold temperatures. This can only be done with a properly volumized tank setup operating on a special set of loading ratios in relation to solvent and plant matter. Using a improperly designed setup requires you to recover and loop the solvent over and over again through the plant matter adding unwanted time enabling the solvent to dissolve excessive amounts of wax out of the plant.

It is better to extract faster and increase production and eliminate the need to extreme cold temps by doing so.

Using a pump with improper volumes of solvent requiring looping effects density, polarization and temperature BTU exchange because the pump vaporizes the solvent during extraction.

The maximum amount of molecules while in LIQUID phase occupy every cubic centimeter of space to maximum density versus when the solvent is being vacuumed with a pump which puts it in gas phase. Using an appropriate amount of solvent in liquid phase in the correct liquid volume is faster gives the most control of contact time, temperature and phase while allowing co solvents to be used to extract other things that butane alone may not be able to dissolve due to non polar limitations. Such as polar compounds. Not everything in the plant that is useful is non polar and dissolved by butane alone.
Only this system gives the ability to extract at low pressure with a cold or hot process, slow or fast for any length of contact time with more than one solvent simultaneously or alone and safely recover the solvent after you use it. This low pressure and low temp pump free process protects the delicate integrity of fragile molecules.
The recovered solvent can be used over again indefinitely due to the gentle nature of distilling at low temperatures and pressures verus the high friction heat and pressure created by a pump.

By using distillation which keeps the solvent in liquid phase it allows us to use a liquid solvent at any temp and contact time to target and or avoid specific compounds based on their physical properties such as molecular size, polarity, melting points, boiling points, freezing points and condensing points. This process starts with a sub freezing solvent because you use the recovered solvent was just condensed by dropping the temp to condense it. Adding heat to that solvent is how you perform a heated extraction. So colder is first faster and ready to go.

A loop system or pump based system brags about speed claiming they are faster because they use less solvent and have less to recover.
The fact is that you have no choice in the matter in how much solvent is required. You have to fill the column and hydrate it with liquid solvent to begin dissolving the compounds that will be washed out by the second and third volumes. You cannot decrease the amount required to do that.
Then you have to wash the second volume out with a third volume because the first and second sort of mixed together.
A portion of the thrid volume will stay behind due to absorption or cappilary action surface tension of the plant matter and liquid solvent.
Just like making coffee or tea. You have to send more liquid in to get that first liquid out.
We offer a volume capacity that allows you to use a 4:1 loading ratio so that you can remove some of the butane solvent and add a co solvent.
This ensures you do not over fill your tank and that you still have a adequate amount of butane.

Pump systems use less solvent and are faster with the pump.
What they dont tell you is this. They are looping that smaller amount of solvent back trhough over and over again until 3 volumes have passed through. Hence the term loop extractor. That 3 volume rule is only if they are using the right temp, right polarity while in liquid phase. Once the pump starts vacuuming the tanks that are holding the solvent, including the one with plant matter in it, the solvent goes into gas phase. Now 3 volumes of liquid density molecules spreads out into 10-20-40 volumes of gas or more. Who knows when 3 volumes of liquid have been passed through then? A sight glass is the only way without complicated math. It is dynamic and hard to calculate. A sight glass shows you a color change from dark to light indicating that the compounds have been removed and nothing is left. Or you just set it for more time than it needs which would be SLOWER.
We have been through all this. This is old news.
Watching these guys start at the beginning and brag about being the most advanced has really just started to get under my skin and should scare the hell out of you.

When using co solvents, is the pump only recovering the butane or is it recovering the co solvent too? As a rule, solvents are removed lowest boiling point first. So how can you be sure you are recovering the co solvent and looping it back throught at a known rate. Dont worry, it keeps getting more complicated and uncontrollable. So rather than tell them what is wrong and how to fix it I will just stop here.

Most do not understand solvent density or hydraulic fluid expansion, thermal expansion and how this effects safety in tank design.
When a fluid is pressed it produces hydraulic pressure which basically means it does not compress and therefore exerts a immediate equal force to the force being applied.
When in gas phase it does compress until all those gaseous molecules are compresssed into a smaller space until they reach a liquid hydraulic state if possible with that particular solvent. Hence the reason CO2 has to use pressure to be effective. Changing the temp of a liquid can produce astronomical pressure forces that are equal to a artificial force created from a hydraulic jack for example. Not understanding how to allow for expansion of heated liquids can be very dangerous. That is more on the subject of tank design. 
In regards to extractions, the rule is this,, liquids connot compress but gases can. For a molecule of solvent to bond with a like polarity molecue in the plant and be carried out that molecule has to be present in abundance and they have to match in their polarity. If you extract with a liquid you will have the maximum amount of molecules present in a Cubic Centimeter of space. With a gas like CO2 or any liquid solvent under a vacuum which can convert it into a gas, such as when a pump is used, you will have fewer molecules present in a cc of space. When in liquid phase you cannot compress even 1 more molecule into that space. It is maxed out. If you filled your tank all the way with a liquid and tried to cram another cc in that tank it would stretch it out or rupture it if you continued withot allowing some of that pressure to vent off via a safety vent.
If any heat hits that tank when full, the liquid will expand. I am talking about a 1 degree rise in temp creating over 1000 psi rapidly. The only thing that prevents this rise is stretching metal. What these fly by night crews that build extractors fail to understand is that hydraulic force is equal to hydraulic expansion and thermal expansion is created faster and easier. In other words, adding temp to a hydralically filled tank can be accidentally done simply by a change of temp in the room completely unseen until the tanks rupture.
It does not matter if I am pumping the solvent in deliberately or if I allow a tanks temp to increase by accident. The result will be the same.

This lack of molecules in a cc of space with gases is why you need more volumes of gas solvent to extract with when using CO2 or a pump system. The pump systems or loop systems may trick you when they tell you that you are using less sovlent and therefore faster. But the truth is that this smaller amount of sovlent is being recovered and recirculated and recovered over and over again a unknown amount of times through the plant because they dont know if it is in liquid or gas phase because they are vacuuming it out and pumping it in at the same time to keep the process going or looping. They actually have to view it when it comes out to see if it is done or needs to keep going. The pumps are ok with CO2 and that does not present much of a problem except that CO2 ruins seals requiring frequent rebuilding of the pumps. But when using a flammable solvent pumps are not an option and do not bring anything beneficial to the table except a little speed which can be had by spending a little more money on the initial design by building faster tanks which would eliminate all future pump expenses and their problems and inherent limiations.

These problems coupled with the risk and contamination forced us to come up with this current solution.

The Tamisium Extractor operates using basic principles of physics without the aid of mechanical or electric compressors or pumps. By taking advantage of the enthalpy physical characteristics of Butane we harnessed the energy released from the butane when heated and cooled. This allowed us to eliminate all these cumbersome expensive practices to move solvent from tank to tank and from gas to liquid phase and back again. Combining all the great features of all extraction systems of the world into one effecient simple to use unit for the first time.
Extract delicate molecular structures with multiple or single solvents to target specific components in a plant and learn to use time and mild temperature, mild pressure and various solvent combinations to expand your product variety and quality. A Tamisium is capable of being run so economically that we will have to reevaluate plants and extractions that were once cost prohibitive.

As you can see from the photographs on the website, you are getting a heavy duty, laboratory quality, food grade, fully capable extraction apparatus. This is a professional tool and system and with it you will produce the highest quality extraction available in the most cost effective way. It is 3 times faster than the current industry standard. 1/3 the cost and produces a higher yield, more varieties and less expensive to operate and far less complex to use.

The Hydrocarbon Solvent of choice is Primarily N-Butane. Organically friendly and NON-TOXIC. This solvent has been used in the food industry for decades because it is one of the easiest solvents to cleanly evaporate away, leaving no trace and does not react with the food products being extracted. You may not be aware that butane is the propellant used in cooking oil canisters. Why not, it is safe, non-toxic, evaporates completely and dissolves the oil readily so it can be sprayed out of the low pressure canister and it provides the pressure to do so. The manipulation of this low pressure created by butane when placed in a closed system (ClOSED LOOP EXTRACTOR) is what you will learn how to use and is what makes this system so incredible and easy to use.

The control parameters we control during extraction allows the most control of any extraction system. They are outlined below.

We call this the 6 parameters or QDTPTP process.

  • Q-uality
  • D-ensity
  • T-ime
  • P-ressure
  • T-emperature
  • P-olarity.

Is is through the manipulation of these repeatable adjustments that you will be able to duplicate any extraction process and repeat what you have done to produce the same consistent product every time.

All done without requiring additional expensive complicated dangerous equipment. When you are done extracting, the apparatus will recover the solvent for reuse and it will clean and separate from your product and any other solvents used with butane, during the recovery process. We even supply a proprietary product and process to remove other solvents used during the extraction process.

But before you can do this you have to understand what it is that you are doing:

It is as simple as this. There are 5 effects you can enact on an extract during and after extraction to isolate avoid or include a specific molecule if you know what they are. With a Tamisium Extractor(Remember Extractors are HIGH PERFORMANCE EXTRACTORS not CLOSED LOOP EXTRACTORS) you can actually enact more of these effects during the extraction process than any other extractor or as with any extracted material you can isolate them after they are removed from the plant.

They are as follows:

1. Size - Knowing the size of the molecule will allow you to filter out various compounds based on size through a series of ever decreasing micron size filters.
2. Melting Point and Freezing Point - Knowing the melting and freezing points will allow you to melt it out or freeze it and avoid it.
3. Polarity will allow you to dissolve it out. Time will allow you to do this more or less efficiently. Once removed you can place different molecules into different fractions of solvents of varying polarity within a separatory funnel.
4. And boiling and condensing points
5. Weight - Knowing the weight will allow you to spin them in a centrifuge and separate them based on their molecular weights.

Time and temperature can allow you to do these things more or less efficicently because time can allow a process to complete and temp can allow that to happen with more or less time. To some extent Temperature can actually change the environment and even the molecular structure which can be good or bad depending on what the change is.
But you wont know what you are including, avoiding or isolating unless you first get it all out, isolate it and have it analyzed.
Using color or texture is not a good way to identify compounds. And isolated compounds can be useless in some forms of ingestion. You may be able to vaporize it and inhale it directly into the blood stream but you may not be able to digest it and get the same result and so on.


This extractor is not limited to essential oil extractions, perfumes or rare botanicals. Use it to extract biofuel from seeds, soil or clean oil laden machinery in a special cleaning vessel. It may be the most versatile extractor ever produced. It is definitely the highest yielding, easiest and lowest cost system available today when all cost are factored in.
