So I completed building my recovery still. While I was able to achieve a -30 bar vac all night I was having a hard time keeping it in balance.
Heat source was slightly in question so moved to electric stove.
I was trying to evap it all the way down to oil and not spend hours cleaning it all up, so I put a silicone mat inside with the corners pinned. after some time I realized that the thermal coupling was probably an issue so I put a bit of olive oil under it and that helped for a moment. I’d get bursts of boiling which sent everything splattering up on the lid then it would calm down to nothing. I eventually got it all the way down with some discouragement.
One thought is that my reclaim chamber is half the size of my loading chamber. I know with a compressor the size of the tank matters as much as the motor. so I wonder if the volume of vacuum of each pot contributes to the systems balance. i.e. a bigger chamber will suck a lot longer when pressure is released than a small chamber will under the same vacuum.
I can post pics and lists later if I can get time. (at work) But has anyone gotten this system to work with a smaller reclaiming chamber?
Also any tips for a newbee about collecting this sacred goo? and should I have just put it in the loading chamber directly, without the mat? I was not prepared for the collection operation lol!!
Well, I assume your talking about the still? basically a way to evaporate the ethanol while re-condensing it back into liquid on the other side. also that alcohol boils at a lower temp at a vacuum.
If you are talking about the end product, well I guess what I am going for is a clean extract that my wife can tolerate. but also I’m looking to refine the oil to possibly vape. essentially a clean oil to use for what ever I need.
