Hi ya'll!
I notice that DK has beaten me to the punch posting our new butane extraction and recovery system and a hearty salute to their design.
I took a little different approach, and mounted a stainless extraction column above electro-less nickel coated paint pressure pot. I pull a vacuum on the overall assembly after filling the column with plant material, and then either flood the column with butane and let it soak, or push pull butane through the column and collect it in the pressure pot.
After soak, I open a dump valve between the column and the collection pot, after which I pump off the butane as a gas, leaving behind the oil in the paint pot.
Cycle time is 49 minutes to extract ~300 grams of material, in the 1 1/2" X 48" column. Depending on starting material, that usually yields from 4.5 grams (fan leaves) to 54 grams (bud) of vacuum purged oil.
To accomplish that cycle time, I had to add heat tape to the collection pot and set the recovery tank in an ice bath.
