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". The current Closed Loop process was created by me the owner of Tamisium in 2004. This process was dropped as ever being safe and effective shortly after. Originally off the shelf parts were used to create the loop process for testing. Later it was decided that custom sealing methods and tank designs were required which led to the creation of the Tamisium Design and Process. Tamisium is a latin word that means to Filter or Seive and was the chosen word used to name the extraction process you see today. There are over 25 companies currently building our old prior art that we evolved away from.

Closed loop extractors is a term given to our old process or more appropriate, process and design. This process was conceived originally due to the cost associated with prototype manufacturing. Cutting cost was done by using off the shelf parts. Cost was also reduced by building lower volume solvent tanks in relation to the column volume that holds the plant matter. That means the tanks in the closed loop design do not hold enough solvent to perform a complete extraction in one pass. This was learned to be a crucial mistake. When looping, by definition of the term, 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 the degree of defiency. A random inconsistent tank to tank volume is indicative that the closed loop designer does not understand the concept of extracting but instead is more focused on cost and the use of a pump to take the place of knowledge in design.

Sight glasses were later added to the output of the plant column to help determine a completion point because when looping you dont know how much solvent has been recovered and looped through. A sight glass shows a color change in your output which is how you can determine when an extraction is over if you dont know how much solvent is required to complete the process. How much solvent is a known constant.

During the multiple recoveries required for looping 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. That is the Tamisium Design and Process.
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 with the safest, fastest, most economical way possible.

We use heat and time to increase or decrease the effectiveness of the that solvent to dissolve those targets or avoid them Then we separate the liquid from the solid plant matter by filtering the plant matter away. After the solvent carries out what it dissolved from the plant matterl those chemical compounds are mobile in a bath of liquid where they can be further moved around and cleaned washed and isolated to ultra high purities if desired. The word Tamisium seemed appropriate when I chose that word as the name for the extractor. 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. Building an apparatus to extract from any plant gave it a versatility that allows us to do anything we want with one system. 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.

When a solvent is used while in liquid phase it means the maximum amount of molecules occupy every cubic centimeter. The solvetn is at Maximum Density.
Liquids cannot be compressed like a gas. While in LIQUID phase maximum density means you have more molecules present in every cubic centimeter of space occupied. This is important because molecues form bonds with chemical compounds and carry them away from the plant matter.

An analogy would be a warehouse with workers spread out over a lot of real estate. To compress all those workers in a smaller space means you can do the same job with a lot less real estate. This means heating, cooling, speed all become less costly and easier to control. When a solvent does not have a liquid phase it is called a sublimating solvent.
CO2 is sublimating. It requires high pressure to compress the vapor or gas into a smaller area so that it can mimic a liquid. This is very costly and is one of the many reasons we omitted CO2 as an option when choosing a solvent to build an extractor to work with.

Although butane is considered to be the holy grail of solvents it is not the only solvent one may need. Other solvents may be required to extract other things that butane alone may not be able to dissolve. Butane is very selective and will extract non polar components from a plant very well. This selectivity is important so that you can target by avoiding the other things but if you need to add other targets you can but you will need to add a co solvent.
CO2 is not very selective which is a bad thing because you cant target as well. You end up with a lesser degree of one thing and a greater degree of more than one thing and with non polar targets you may only get 50% of them out. If you want to fine tune CO2 for non polar things that Butane does well all by itelf you will have to add a non polar solvent like butane or hexane or propane but even then the yield will be much lower than a selective solvent like Butane. With Butane you can target or change the target.

In addition to changing polarity by adding solvents a Tamisium allows you to change the solvent completely. You can extract with any solvent that has a boiling point or pressure that the tanks are rated for. Ethanol, Diethl Ether, Acetone and so on. Or you can combine those to target everything and all those other solvents are all liquid phase solvents. We just consider butane to be the safest choice because it can be recovered without a pump and is so selective while still being miscible with other solvents that we can use to expands the target range. It is like having a stereo with a volume control that goes from 1 to 10 versus 4 to 10.

When choosing a pressure rating we did not see any need to increase the expense of the system by building high pressure tanks because those higher pressure solvents were flamable and required a pump to recover them. Higher pressure solvents have lower boiling points and therefore lower condensing points which put them out of reach for safe distillation. For example, propane is not as selective and has a boiling point of -55F. Not so practical a temp to achieve for condensing so most just use a recovery pump with propane. Adding a recovery pump would make it unsafe and those solvents provided no effective gain in performance, speed, range or ability.

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 that we find in aromatics and flavorings or terpenes.
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 instead of pumps during solvent recovery we separate the extraction process from the recovery process and keep it all safe and silent while simplying the process and reducing labor and cost. Making a super fast process that evaporates more quickly does not disallow the pumps from being used but it makes them uneccessary. In reality adding a pump to speed up a fast process will just make it faster. So if one is every created that will not leak of fail we can still use it but the process will work fine without it.

A loop system or pump based system can recover fast because they use less solvent and have less to recover but the truth is a little more complicated.
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 volume. That first initial soak is stuck in the plant column and requires more to wash it out.

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 use an adequate amount of solvent to extract from the coffee beans. You add more beans and you have to add more solvent. I may add that grinding the beans helps a lot and using hot water helps even more especially when adding sugar.

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 and you can get the same high yields when extracting cold.
This addes space also ensures you do not over fill your tank and that you still have a adequate amount of butane to complete your extraction.

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 an immediate equal force to the force being applied and to the tank that holds the liquid.
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.  

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:

 There are 5 effects you can enact during an extraction. With a Tamisium Closed Passive Extractor you can actually enact more of these effects during the extraction process than any other Extractor.

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. 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.
