I'm from the microbrewery world so forgive my ignorance on this one.
I contacted my mill supplier for a distillery build and he mentioned that he thought that maybe a mill in a distillery would require an explosion proof motor on it. I know that pumps moving distilled alcohol need to be explosion proof but what about the other motors; CIP, liquor back, wort wash transfer, mill. I'm designing the facility to have the usual separations; mill room, boiler room as well as separating the storage, still, wash and ferm rooms and thought that this would be sufficient. What's everyones experience and advice?
