anyone doing protein rest with their RIMS?

[augiedoggy]

I used regular 1" stainless pipe nipples with regular tees at each end with reducers however now I see they have tees with a reduced female opening in them. I used a larger 1" camlock fitting to pull the end tee with the element mounted in it and to be able to clean out the rims easily if need be. I have never needed to disassemble my fittings in my rims tube dispite it being threaded together.. I do run pbw through it to clean though.
at the brewpub its a different story, I use tri clamp spools and tees to make it all more sanitary.

I also use my chugger to pump for mash recirc, probably about the speed of those tan pumps at full bore. That faster speed may be why i'm not seeing protein build up. My cartridge eleme is 19mm, so about 3/4" in diameter so it's on the larger side.

I also don't do a protein rest, I've never done a batch with under-modified malts.

I would like to figure out a way to wedge a thermowell between the folds of a foldback element.

Maybe you are joking, but you wouldn’t want this. The liquid is heated along the whole element.

Which brings up another important consideration. The RIMs tube design should minimize the dead space inside and maximize turbulent flow (or at least prompt good mixing). Heating the liquid in a laminar manner, meaning the same liquid runs along the surface of the element is not desirable. In order to achieve a net liquid temp, that heated liquid is mixed with a lot of unheated liquid, which means it needs to get hot and impart that heat “locally” to a small volume of liquid. However when the heat gets rapidly distributed, local heating is reduced.

You can either wrap your element in stainless wire or add baffles to aid in mixing. Using the smallest tube diameter to fit the element is also desirable.

No. I'm not joking.

Have you tried it?

I once bought a cartridge heater with an actual j type temp probe built into it... I could not get it to work and maintain steady temps. I imagine there might be a similiar case here although I assume you mean to wedge a probe into a space between folds at the far exit end on the element which may work if the rims had enough time to reach an equilibium there. on some elements there are hotter spots depending on how the element is made.

Modified malt vs unmodified conversation aside, We had a mistake on our first brew session with the 3bbl system and mashed in at the 130s range... a stuck flow issue caused it to take hours and turn into a step mash of sorts, the result was a higher gravity super clear dry beer with a final gravity of 1.002 the mash profile definitely made the beer clear up quickly compared to how it normally comes out. We called it Oops blond ale and it was the first of our beers to run out last night as people really liked it. That said we have since brewed it again the correct way and it was cloudy going into the brite tank the other day.

Interesting. My last brew I had unterteig issues that clogged my filter bag. I had to stop and start a cpl times at different step temps so your episode gives me hope. When I dumped the grain bag there was a definite layer of teig. Not sure if it was the Barke Pils, the Acidulated malt, the Melanoidin malt, or what.

No. Because physics. Your element/local liquid temp will not be the exit temp.

Ok. Well, you do you, brah.

Because, Physics.
