Anyone have ideas on how to reduce the noise from my still mixer/auger. Its very loud and we have a super small distillery with a tasting room at one end. I am trying to make it so I can produce and sell bottles at the same time, its difficult with the mixing blade going. I tried building a plywood box around it and it didn't help much, also tried acrylic. Its also hard to tell if it helped at all, after listening to it all day. Any ideas?
