Default Good Efficiency with Un-Modified Cooler?

first off, apologies for the crappy image. my scanner is not working properly, so i had to resort to a cellphone pic.

my original MLT that i built is just too small it turns out. so until i decide i need a new one, i was thinking of trying this technique with another cooler i have laying around:



anyone done this before? do you think i will be able to get a decent efficiency using this set-up?

Looks like it will work. Doubt you will get anything fantastic for an efficiency increase. Personally I wouldn't bother with the colander either, just looks like more trouble than it's worth.

A few little suggestions.
The colander could be useful for fly sparging, but wouldn't serve any useful purpose for a batch sparge where you need to add the water and stir well before vorlaufing and lautering.
The braid would OK for a batch sparge, but not good for a fly sparge.
Extend the length of the outlet hose to the bottom of the kettle. This will minimize any HSA problems, and improve the siphon from the MLT to the kettle.

-a.

I would absolutely batch sparge a "macgyver" rig like that. Might be a bit of a hassle. Should wourk fine. You might want to flip the racking cane so the end w/ the curve is in the tun letting the braid rest on the bottom. My cane has a 90 degree bend.

I think you may have issues with keeping the siphon going when it gets down towards the bottom. As soon as you it sucks any air you will loose the suction.

Why not just setup a "brew in the bag" system until you get a new MLT? It seems many people are getting high efficiency with that system. How much grain are you trying to mash?

I am about to test my new setup Friday. It does not require you to modify your cooler either.


My pic makes yours look good. I am not sure i am going to bother with the colander part.

Batch sparging is not as equipment dependant. All that really matters is the grain is well mixed w/ the proper temp sparge water and drained. With fly sparging, manifold dimensions are critical to achieve a thorough rinsing of the grains without channelling. This is why most fly spargers will use a false bottom or a manifold that covers the entire bottom of the tun. With your basic set up, there is a good chance that the sparge water will find a "short cut" to the braid and not rinse the entire grain bed. W/ batch sparging you mix the grains and sparge in batches and drain the entire tun and rinse the grain in "batches" rather than a continous rinse w/ fly sparging.

I see no reason why one couldn't siphon out of the mash tun w/ a proper set up. You do want the braid to lay flat on the bottom to completely drain. Your sketch shows the braid bent at a 90 and I fear it might kink and limit flow.

yeah, losing siphon could be an issue. i guess a false bottom would probably be better than a braid huh? what's a good trimable false bottom material? if i could make something simple that i can just put in the cooler when i need it, that would be nice.

as for the grain bag option, i just don't have the kettles. and those things are expensive!
