TE12000 Extraction Summary
TAMISIUM TE12000 - EXTRACTION SUMMARY
The process begins with a pressure checked full Solvent Delivery Tank. The Solvent has been placed in the tank and it has been pre-chilled or heated to the desired starting temperature. The solvent Delivery tank has just recovered the solvent from a prior run and should be cold to start. (For Volatile Extractions we recommend Normal Butane that has been cleaned by distillation using the Tamisium Extractor)
STEP 1 – ATTACH YOUR SOLVENT DELIVERY LINES
Connect one end of the solvent delivery line to the top of the solvent delivery tanks liquid siphon center exit valve. Connect the other end of the solvent delivery line to the top of the column liquid center inlet valve.
STEP 2 – ATTACH YOUR RECOVERY LINES
Connect one of the 3 ends on the Recovery line to the top of the column vapor outlet on the side and the top of the Extractor Tank Vapor Outlet as indicated. Connect the third end of the Recovery Line to the Recovery Tank Vapor Inlet Valve.
STEP 3 – BEGIN EXTRACTING
After your solvent or solvents have been combined and set to your desired solvent temperature in your Solvent Delivery tank, you can then use the heat inputs on the solvent delivery tank to create the head pressure to expel Solvent from the liquid siphon line in the Solvent Delivery Tank into the column of plant material to prime with a full liquid saturation soak at any desired temperature for any length of time.
Note; Solvent temperature will not be increased by the heat used to create the head pressure so long as the solvent is allowed to expel from the tank during heat input.
To perform a temperature controlled extraction leave the solvent delivery tank liquid output valve closed during heat input until you reach your solvent temperature setting commonly ranging from -40 to 120F
To perform a low temperature extraction you can omit closing the solvent delivery valve. It can be left open until the Solvent Delivery Tank is completely empty.
As low as 5 minutes total contact times can be achieved before starting a full recovery of all the solvent from both the extractor tank and column of plant material.
Why do all liquid solvation extractions require 4 times more solvent than the column will hold?
This first volume of solvent that enters the column is the solvent that does 90% of the extraction. It has also absorbed into the plant matter and will not exit until the remaining solvent from the solvent delivery tank washes it out. The second volume mixes slightly with the first and the third volume mixes slightly with the second and so on. It is known that by the 3rd and 4th volumes very little desired compounds will remain in the plant matter. It is the third volume of solvent that washes the plant clean of any dissolved compounds. The fourth volume stays in the plant matter and must be recovered from that position. Although these volumes are mentioned as separate actions however they flow though in one continuous cycle.
STEP 4 - SOAKING
Once you observe the solvent flow out of the bottom of the column into the extractor tank you can stop filling by closing the inlet valve on the top of the column. Closing this valve creates a hydraulic vacuum on the top of the column that holds the solvent in the column area. The filter below prevents the liquid solvent from exiting the column. This will allow you to soak your column with solvent for a specific time at a specific temperature to target specific compounds. If no soak time is desired, keep the Column Inlet Valve open until the SD tank is completely empty.
STEP 5 - STARTING RECOVERY
Open the outlet valve on the extractor tank, the inlet valve on your recovery tank, and the connecting valves to both recovery tanks if both are being used to recover in series. Using both recovery tanks cuts your recovery times in half by doubling the condensation surface area. Open the top column vapor outlet valve last until it has had time to drain sufficiently preventing any solvent from bypassing the column. Be sure your extractor tank heater is set to 90F – 110F and your column is 5 degrees warmer to help the heat penetrate into that plant matter.
Remember there is no liquid inside the column to help transfer those BTUs to the core. Although the column is smaller it will take just as long to evaporate all the solvent absorbed inside.
KEY NOTE - It is imperative to safety that all the butane is evaporated from your column. The process is designed so the column finishes first so long as you use a 1:4 loading ratio.
STEP 6. DRAINING INTO THE SUCKER / DRYER TANK.
Just prior to recovering all the solvent from the extractor tank use what remains to drain your extract into your Sucker Tank where the final phase of recovery can take place after which the tank can be relocated to another work area where it can be dried down to 0 parts per million readings of any trace solvent.
STEP 7 – CLOSING THE WAFER VALVE AND REMOVING THE COLUMN
While waiting to recover the final trace amounts of solvent into the same Recovery Tank from your dryer tank, you can break the system down to expel your spent column of plant material and reload it to perform another extraction. Or you can have a preloaded column ready to go.
Emptying the column is a easy job with the removable perforation plate that expels the column contents from below. If you have not closed your wafer valve already be sure and close your wafer valve on your extractor tank to seal it so you can safely remove your column to prevent filling the work area with flammable vapors expelled from your extractor tank. This also prevents solvent loss from solvents that filled and vapor locked your tank.
The extractor tank is self cleaning and will never need to be cleaned so long as you drain into the sucker tank. It is common to perform as many as 5 extractions and full recoveries before opening the Sucker / Dryer tank to access your finished product. This allows you to eliminate unnecessary steps involved in removing your product from the dryer tank when extracting repetitively from the same material. The sucker tank also serves as dryer tank to clean your final product of all residual solvents.
STEP 8 – RESEALING AND PRESSURE CHECKING ANY OPENED TANKS
Any opened tanks would need to be pressure checked again. This would be the Sucker Tank once cleaned and resealed and the column once filled and resealed. They are pressure checked again each time because those are the tanks that have had their seal broken. If you do not drain your extract out of the extractor tank into the sucker tank you will need to reseal that tank and pressure check it after removing your extract from the extractor tank.
Choosing not to drain your extract from your extractor tank into the sucker tank is not recommended for safety reasons as well as inconvenience, time, labor and overall cost.
The process is complete.
