HedgeBird Posted October 30, 2018 Share Posted October 30, 2018 We are in the process of upgrading our mash tun from one with a separate steam plate and cooling jacket to a new larger mash-tun that has only a single steam jacket. I am wondering what folks who have single jacket mash tun, and who do grain is mashes are doing for cooling the mash? Are most of you running both steam and cooling (water or glycol) through the same jacket, or are you using a separate heat exchanger? Out details: Old mash tun is 150 gallon (has separate steam and cooling jackets) Link to comment Share on other sites More sharing options...

Old Glory Distilling Co. Posted October 30, 2018 Share Posted October 30, 2018 We direct inject live steam to heat and use the jacket to cool. 1 Link to comment Share on other sites More sharing options...
MG Thermal Consulting Posted November 3, 2018 Share Posted November 3, 2018 Tube in tube for whiskey, plate and frame for worts like vodka and rum are the least expensive and work best. Link to comment Share on other sites More sharing options...
ViolentBlue Posted November 4, 2018 Share Posted November 4, 2018 put side by side, identical mash, identical cooling water avaliability/flow using steam jacket to cool a 300 gallon mash took 1.5 hours using the ladder frame tube in tube wort cooler took 20 minutes https://www.cageandsons.com/type-aux-wort-cooler Link to comment Share on other sites More sharing options...
Broken Anvil Distilleries Posted November 4, 2018 Share Posted November 4, 2018 We have used both cooling in steam jacket and by the addition of carbon filtered (ie dechlorinated) water to final volume. Is there a downside to the latter that I'm missing assuming we are tight with our volumes to ensure we arrive at our preferred pH and SG? Link to comment Share on other sites More sharing options...

MG Thermal Consulting Posted November 5, 2018 Share Posted November 5, 2018 The more efficient the heat exchanger, the more cooling you require, which is why I specify some kind of reservoir for everything except cooling with city water- but then this is so expensive, I specify a reservoir for that too, and for well water applications- hardly anyone has enough well capacity to run everything, too often the wells run dry. That way you can use a much smaller chiller. Link to comment Share on other sites More sharing options...
Southernhighlander Posted November 5, 2018 Share Posted November 5, 2018 Another great option is a cooling coil in the mash tun itself. Ours crash cool in around 30 minutes. Link to comment Share on other sites More sharing options...

We spent a lot of time designing both. The position is such that cleaning is not an issue. We have around 40 mash tuns and combination mash tun stills in operation with internal cooling coils.

Luv2Learn Posted November 11, 2018 Share Posted November 11, 2018 Is there a reason I am not thinking of - why I would not put it in my jacketed ferment tanks and use the jackets to cool in the ferment tanks? I am a new distillery owner and that is our current process but learning as I go...... Link to comment Share on other sites More sharing options...

You can certainly do that as long as either (A) you pump over or (B) you have an agitator -- either fixed or transportable -- in your fermenters. If you don't have either you're ferment will be completed (or stalled due to overheating) by the time its cooled. Link to comment Share on other sites More sharing options...
MG Thermal Consulting Posted November 11, 2018 Share Posted November 11, 2018 That is more common technique when cooling with an external exchanger, but it depends on how much surface area you have in the fermenter jacket, if you don't have it all the way around, it's problematic.

Our fermenters have very small jacketed areas so it would not be practical to use ours for the initial crash cooling. Link to comment Share on other sites More sharing options...
