Propane is 5 - 6 lb of solvent per lb of dry material, I’d say.
I figured it was more. Just wasn’t sure, as I haven’t used it by itself, yet
Propane by itself is pretty nice. I’ve also had really good results using it hot. Stink your tank in a bucket of steaming hot water for about a minute or two (till the top of the tank feels warm), not too long or the pressure will get too high for the tank, depending on how much gas is in there. I’ve seen consistent 18% - 20% yields of saucy golden sugar from using hot propane on good trim. I bet you can find out and even better tek, though!
Try soaking cold, then letting it warm up in that same # range, 20-30mins
Do you think you’re pulling a bunch of undesirables at that point? 18-20% on trim is pretty rare in my experience.
Anyone else have more data on the subject, what the different hydrocarbon yields are from different ratios like a 3 to 1 (solvent to material) vs a 6 to 1? Plus how long soaking affects all this.
