Tamisium High Performance Extractors, Botanical Extractor or Herbal Extractors solve the problems of closed loop extraction processes.

Before you begin your journey in regards to learning about why one extractor is better than another or who Tamisium Extractors is, lets clarify the single most misunderstood term. "Closed Loop Extractor".
Closed loop extractors is a term given to a process or more appropriate, design, where the manufacturer chose by ignorance or inention to cut corners on manufacturing by building lower volume solvent tanks in relation to the column volume that holds the plant matter meaning the tank in the closed loop design does not hold enough solvent to perform a complete extraction in one pass. Therefore the solvent must be recovered and looped back through repeatedly until a sufficient amount has been used to complete the extraction. How many times one loops the solvent depends on how far off they are in their volume ratios. A random inconsistent tank to tank volume is indicative that the closed loop designer does not even understand the concept. Citing fast recovery times may not include the muitiple times closed loop extractors are required recover AND loop. Sight glasses were later added to help them determine a completion point because when extraction is complete the color lightens. 
During the multiple recoveries the Closed Loop extractors add contact time that allows the solvent enough time to dissolve unwanted lipids and dark compounds from the plant. Oils are disolved easier and therefore first, then waxes and as the plant matter fills with solvent other dark compounds are washed free and carried out. The added time forces the user to add extreme cold temperatures to restrict the solvents efficiency in an attempt to counter the effects of the added time.
This can all be avoided by simply building a correctly volumized system that holds enough solvent to avoid looping.
Single pass passive systems extract faster than closed loop processes and allow you to add differing polarity solvents and added time, heat and cold when needed. In other words you can achieve your goals many different ways as you attempt to add these controls back in to maximize your yields the fastest most economical way possible.
I know all this because Tamisium created the closed loop art and dropped if over a decade ago. That bill of materials to build those systems we built during our research surfaced and cirulated creating nearly every extractor you see today.

Who or What is Tamisium?
Tamisium is a latin word meaning to Filter or Sieve. After all, is that not what we are doing. Putting the plant matter in a liquid solution and filtering it out. We choose a liquid that matches the polarity of the desired chemicals produced in the plant. We use heat and time to increase or decrease the effectiveness of the that solvent to dissolve those targets or avoid them and then we separate the liquid from the solid plant matter so that all those chemical compounds are mobile in a bath of liquid where they can be further moved around and cleaned washed and further isolated to ultra high purities if desired. The word seemed fitting when I chose that word as the name for the extractor you see before you. The specifics regarding how much, how wide, how short, how large, conduction, convection, surface areas, speed and so forth were sorted out while extraction from many different plants until we ended up with the system we have today. The design has not changed in several years but what it can do changes every day. Please join the thousands before you and take advantage of all our hard work as I share with you my design and knowledge so that we can all leave the world in a better safer healthier place.

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 the unsanitary dangerous 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.

It is better to extract faster and increase production and eliminate any requirement to use extreme cold temps that are labor intensive and costly. There are 6 controls that you can effect during an extraction process. Quality of Material, Density of material column and solvent. Temperature of the solvent, Pressure, Time of contact between solvent and plant matter and the polarity of that solvent choice. QDTPTP.

HVAC air conditioner recovery machines are an inherent part of closed loop process or poorly designed system and remove your controls due to the following principles. 

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 Closed Loop Extractor, Extractors, Botanical Extractor, Herbal 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 through 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. 

Using gentle low pressures and temperatures you can 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.

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 Closed Loop Extractor, Extractors, Botanical Extractor, Herbal Extractor(Remember Closed Loop Extractor, Extractors, Botanical Extractor, Herbal Extractors are HIGH PERFORMANCE Closed Loop Extractor, Extractors, Botanical Extractor, Herbal ExtractorS not CLOSED LOOP Closed Loop Extractor, Extractors, Botanical Extractor, Herbal ExtractorS) you can actually enact more of these effects during the extraction process than any other Closed Loop Extractor, Extractors, Botanical Extractor, Herbal 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.
