When using a Lil Terp or Tamisium without a dip tube, you can turn the thing upside down and the liquid in the recovery tank drains back into the column. If you leave it upside down it soaks.can you elaborate a little on inverting it to re flood please?
So basically your just taking one column volume and circulating it 3 times?I mean that you can continue to move the LPG from the collection tank to the column and back, by inverting the system and turning it back upright.
If you just shoot the LPG through the column one time, it isn't saturated by the time it makes it to the collection tank. It doesn't make a mess, because it is unsaturated LPG at that point.
So basically your just taking one column volume and circulating it 3 times?
How do you get the DI slurry out of the sleeve while still attached?We typically make a cotton candy extraction and run our water bath at ~70F <85F and during recovery, flood our column jackets with 150F water.
So this setup uses the bottom-fill overflow as the top-fill by turning valves? The BVV one pictured earlier uses separate top fill and overflow hoses. Which is better and why?i think i may go with this set up.. essentially its just a slightly modded mkIII terpenator.... @Graywolf any special tips for running this passively?
other then the 3 column volumes you mentioned.

deja-vu....How do you get the DI slurry out of the sleeve while still attached?
Fill the column with hot water(150f) eventually the valve will thaw enough to open it then a short while after that your slurry will start to drain. I only fill my dewaxing sleeve 1/3 full of dry ice and alcohol for just for this reason as well
So you add water to alcohol/DI. What do you do with it after this? Waste?deja-vu....
When we used water to melt the dry ice slurry the water just froze...solid.So you add water to alcohol/DI. What do you do with it after this? Waste?
What temp water did you add and how much slurry was in the columnWhen we used water to melt the dry ice slurry the water just froze...solid.
Hot as the tap makes, Probably 125° or so. Is emptying the sleeve necessary on a bidirectional system with active recovery?What temp water did you add and how much slurry was in the column
We don't put DI slurry in the sleeve, we simply freeze the column of material to -18C/0F and use LPG between -30C and -50C. The material stays frozen during the process and we open a three way valve to flood the column jacket with 150F water at the end of the cycle.

My design floods from either direction and a bottom flood gives more even wetting and vents vapors better. The top rinse reduces what is left behind.So this setup uses the bottom-fill overflow as the top-fill by turning valves? The BVV one pictured earlier uses separate top fill and overflow hoses.

I guess I'm still missing something... Doesn't heating the column default the purpose of freezing your material and solvent?We don't put DI slurry in the sleeve, we simply freeze the column of material to -18C/0F and use LPG between -30C and -50C. The material stays frozen during the process and we open a three way valve to flood the column jacket with 150F water at the end of the cycle. T
The 3 way valve allows us to circulate the hot water in a loop until we need it, then flood the column, followed by draining it, simply by changing valve position.
