How To Distill Moonshine Fir Higher Proof? - Moonshine info

Mar 29, 2022 We utilize a molecular sieve to remove the final 5 percent of the water from the mixture in order to obtain pure, 200 proof alcohol. The pure alcohol has been transported to storage tanks and is now ready to be sent to its final destination. The water and maize solids that remain after the alcohol has been extracted are referred to as stillage.

Molecular sieve - Distillers Wiki

Molecular sieve. A molecular sieve is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be absorbed, while smaller molecules can. As a mixture of molecules migrate through the stationary bed of porous, semi-solid substance referred to ...

obviously depended on the pore size of the molecular sieves. Figure 2 also shows that the 3 , 4 and 5 molecular sieves were capable of breaking up the isopropanol– water azeotrope, which occurred at ca. 13 wt% water content (Westgate and Ladisch 1993). The 3 and 4 molecular sieves were capable of producing dry alcohol in the first
