I'm thinking about trying a larger (+5lbs) scale ethanol extraction but a partner of mine keeps trying to convince me that butane is the way to go and the ethanol is way more labor intensive/ expensive and ultimately is less efficient extraction method and we'll be leaving yields on the table.
Our goal is to after we have the oil to fraction later but in regards to extraction our plan is to have all materials sitting over night in a -30 deep freezer and take the dried frozen starting material an extract it in a large vessel which is also in the freezer using 190proof grain alcohol. Then filter inside the freezer using a Buchner and then rotovap distill the alcohol back
My question is;
Is anyone successfully making large scale extraction with ethanol? How are the yields compared to a bho setup of the same size? Is ethanol more labor intensive compared to butane blasting? Our alcohol was not cheap but neither is good grade butane. Is one process substantially cheaper than the other ?
