If you use the cage tote idea (IBC) be sure of what it contained before. Do not think you can safely remove non food contaminates from the pores. Once used IBC totes that had cooking oils, mild fruit juice concentrates (I used one once that originally contained vanilla extract, vanilla is one of the subtle flavors in maple syrup) and such are good.
Then wash it out completely.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
