Study Finds More Effective Way To Dry Ethanol, Reduce Costs

ladisch said tests found tapioca collected about 34 percent more water than corn. molecular sieves, while effective, eventually wear out and create waste that must be disposed of. the tapioca can be dried and reused, and when they wear out, they can be used to make more ethanol. 'tapioca is very efficient, and it's all-natural,' ladisch said.

typically, this equates to 6 or 7 cycles in total to dry about 25 grams of sieves. this works very well to produce sieves for drying ethanol. however, if you prefer a 'set and forget' procedure, i don't think anything can beat placing sieves in a small oven set to above 250 c for a couple hours.
