Getting the biomass out is still no fun. I’ve got an air powered drill to run mine, although Ethanol at -40C is not super easy to set on fire with a dewalt**. If you’re going larger than 15 gal of solvent, you’ll want a longer reach, and two handles on your drill. Clamping the agitator down would prob…
