Sparge arm..

[Clint]

Hello all,I'm thinking to go with my new tun manifold I might buy or make a sparge arm of sorts ..
There's a couple of options...buy a rotating type or make one...either rotating or fixed.
My tun is the blue cube igloo type. Are rotating better than fixed? If I build a fixed type should I go for a circular type or a grid type?
Thanks in advance!

A shower rose might work well? The kind described as 'rainfall' or similar.

Rotating is far more mesmerising.

But the boring answer is likely no. You are only trying to spread the application of water, and not dig holes like a jet of water would do. A perforated plate will do the job (ask all them one-pot - e.g. Grainfather - users), or some folk are using perforated baking foil. I've used nothing for years (except when I'm using a Grainfather), I just open the tap enough not to seriously flood the grain but keep 1-2cm of sparge water over the grains.

My sparge arm is now redundant. I can get good enough efficiency with a 10-15 min batch sparge in the mash tun (coolbox) and save about 40 minutes of faffing about and worrying about sparge water temperature that gets too low.

Get yourself a large grain bag for the coolbox and do batch sparges, it's a winner.

What advantage does the grain bag give, @cushyno , If you don't mind me asking?

I did wonder especially if you keep a head of water above the grain bed then it wouldn't matter ..
I'll try the new manifold with a foil topper tomorrow.

+1 for the perforated aluminium foil, what I also used to do with an esky mash tun is have a piece of polystyrene cut to size to fit over the grain bed, improved the insulation no end.

I use a spray ball for recirculating in my cool box mash tun and then batch sparge but also recirculate that too

I use a grain bag too. You get virtually no dead space, no stuck sparse, good filter and easy clean up. Plus it’s cheaper and easier than fitting a false bottom.

I can just lift it out of the mash tun, drain wort onto first wort hops in a spare FV, then start the batch sparge off in less than a minute.
No messing with stuck sparges, sparge arm, false bottom or bazooka.
