A controlled study in hot side aeration perhaps?

I love gadgets as much as the next guy...but I've always wondered about this component of the system. You really only need to stir well at the beginning to ensure there are no clumps/doughballs....then it's kind of a moot point after that. Isn't this just another piece of gear to maintain/clean?

Depends on if you are doing any kind of temperature control. Temperature can have a wide variation within the mash if you don't stir.

Exactly, decoction on a 12 gallon batch scale is a PITA to stir back into the mash. I am looking to automate to insure better temperature evening throughout the mash schedule.

On this last batch I had temperature stratification and my floating thermometer only reads so deep. I did a test run before with water and didn't "loose" as much temperature as my thermometer says I did in my mash this time. I was afraid I overshot by 4*, then didn't get a proper reading until I removed the fraction for mash-out decoction and the thermometer held right at 152*F where I had hoped it was for the sacchrification rest. So, top part of the tun was over temp, and I bet the very bottom was under temp. Constant stirring without adding HSA would fix this.

I want to go with a completely submerged type of mash rake that really just combs the mash horizontally to break up any channeling (from steam injection from the bottom, or during sparging). The only part of my design seen from above the grain bed is the down shaft and maybe a few of the rake fingers after pulling a decoction.

Unless you are slow speed and high torque, I wouldn't do this. HSA is going to happen even though it is a myth IMHO under relatively normal home brew situations. This would be like whipping it full of air without the slower speed and enough oomph to turn that slow.

I am going with an ice cream machine motor because of this very thing. It really doesn't move fast enough in a cream mix to whip air in, and has enough torque to turn almost completely frozen cream once the ice cream is almost done. They are made to run for extended periods of time (unlike a drill), and should be able to run perfectly in a thick to thin mash (provided you don't put enough resistance in blade area-which is why I am going with thin fingers). Also, if it wears out, they are easily replaceable with a trip to the store. Rival makes a nice, cheap, powerful 6 qt ice cream maker. This is just my two cents of course. I have made one before with copper tubing as the stir blades and it worked just fine. The only problem is it was on a much smaller than my scale brewery.

Excellent answers. I didn't want to sound like Debbie Downer...but the more I brew, the greater respect I get for those "solid" pieces of gear that are indispensible...you know....things that are all about utility but not necessarily very high on the *wow* scale. I've spent a lot of time completely enamored with gadgets, etc. but find that there are only a few that I keep coming back to, and several that sit on the sidelines

Question: Are you guys pulling the stirrer out at the end, letting things settle, then recircing with a pump for clarity?

My stir motor runs at around 60 rpm... I dont worry about HSA.
Yes that is how I do it. Then I run the pump till it clears.
