When determining proof when a spirit has in excess of 400 mg/l obscuration are you required to follow this method or can you simply distill and proof using a lab still? Video referenced is determining proof obscuration by evaporation. Thanks,

Looking for any helpful tips or DIY equipment to separate liquid from a corn & malt mash. We have been doing this by hand using filter bags at about 3 gallons at a time but this is very inefficient and doesn't always work when doing a 50 gallon wash. Saw that King's County uses a machine that does solid/liquid separation very well but it costs about $25K, so that's not going to happen. Any help would be greatly appreciated, thanks in advance.

We were talked into a plate press to separate beer liquid from mash solids. Has anyone used this method?. We are not having any positive results. The plate filters clog up about 1/2 way through the plate stack, so that only some of the plate cavities are dry pressed, the others are a floury mess. I have heard that several breweries are using this method but the ones I have talked to are pressing/filtering pre fermentation. They also say that they grind their flour quit fine which makes me wonder why our press is clogging up?. We are coarse grinding. The system was designed using samples of our mash and process information. JOHN BROOKS and MICRONICS have given us very little assistance since the Plate Press was dropped off (3 months late). John Brooks had a pump technician drop by for a day to review the AODD pump which is working correctly but she had no knowledge of Plate Press operation. We installed a HUGE 7.5 HP compressor to maximize our air needs. Our plates are always stacked 1-3,1-3, we have tried short stacking, slower-faster feed rates on the AODD pump and AIR COMPRESSOR, premixing the mash slurry so pumping is consistant. Any ideas? Thanks, Doug

We have recently experienced some problems when using the standard TTB procedure for determining ABV by lab distillation of liqueurs containing above 30% solids, especially if we have milk solids present. If we start with 100 ml of sample, add 50 ml of rinsing water and then distill off the recommended 96 ml what is left in the boiling flask is so thick that it is impossible to deal with. The actual ABV of the sample is known because we know how much neutral spirit had been added and we know the total volume (from the total mass and measured density). This corresponded very closely with the ABV calculated by AlcoDens LQ, but the lab distillation always gave low results. I suspect this was due to carry over of solids. Even commercial lab results were quite far from the known ABV. We modified the lab distillation procedure and are now getting much more accurate and consistent results, and I would really appreciate your comments if you have experienced similar problems. In our modified procedure we still start with a 100 ml sample but we add 200 ml of water and then distill off 196 ml (which we make up to 200 ml), leaving approximately 100 ml in the boiling flask. This means that the initial solids are still in 100 ml and remain nicely in solution. My calculations show that for a sample containing 15 ABV this procedure will recover +99.99% of the alcohol. Since the alcohol that was initially in 100 ml is now in 200 ml the measured ABV has to be doubled. We understand that this halves the precision of the measurement but the results are so much closer to the known value and are much more consistent - and the glassware is much easier to clean afterwards! How have you gotten around this problem?

Hey have a 200 liter boiler that i would like to add agitation too. I would like to both speed up heat up time and avoid scorching issues... The agitator would have to tri clamp onto a 3" ferrule and be around 16" from the top of the ferrule into the wort... I'd like to do this as cheap as possible and preferably an electric motor as apposed to an air powered. This is a commercial environment so i assume the motor would have to be explosion proof? Any help or suggestions would be greatly appreciated....
