K-RIMS build question

[CodeSection]

@brianccarr, I have a 2 vessel K-Rim system and use a false bottom in my MT. It works well. I have no experience with a bag.

If you already have both then just try them and see what works best. I always get less kettle trub when I use my false bottom verses a bag. If you dump everything into the fermentor then it does matter but I only ferment clean wort.

@mongoose33, I am with you on not really seeing the benefits of the K-RIMS. I can see the benefits to the Brew easy approach as you can do it with one pump. Mash tun could be a smaller size kettle than the boil kettle to save a couple bucks.

Doing full volume you lose efficiency unless you have bag. I think though you could do a cold water fly sparge to get some efficiency back.

One thing with the two vessel full volume over a full volume one vessel system if you have the proper size kettles you could do a thicker mash and just cycle through the mash to start then start cross cycling later. That would allow a fast temp increase step mash over a one vessel system.

I've been trying to implement LODO techniques, for the most part successfully. The K-RIMS approach, given that it has the wort open to the atmosphere, is a nonstarter for anyone trying to do that.

The benefit is that it effectively increases the volume of hot liquor you can use during the mash, which will increase your batch size if you're limited to a no sparge two vessel system.

My old system was designed to operate in several configurations, one of them being horizontal K-Rims. You can do lodob with this set up if you used a floating mash cap in both vessels, or get a couple of those nifty sealable Stout vessels.

I don’t plan to have any lids off after dough. Not sure I understand the LODO concern here. After dough in, the lids on both kettles will do on through the duration of the mash.

Not sure if the “why” question was answered... K RIMs is a step up from BIAB... single power element, but a normal mash recirculating through a grain bed rather than removing the grain out of the boil kettle. Can also cold water sparge easily if desired.

The lids might be on, but the air beneath them is the issue.

I am not getting/following this, can you please elaborate on this a bit.

Because it uses two vessels during the mash, there is a larger volume which allows one to use more hot liquor (water) for the mash when compared to a single vessel.

Also don't forget, if you do the pre boil step you will need to consider how to accomplish that in this type of setup.
