Default Going to build a MLT. What to use for sparging?

I am going to build a round MLT cooler as I want to start AG brewing, and have seen the blichmann auto sparge and the sparge-o-matic.

Which one are you using? Which one is better? I only want to do this once

Thats not a bad idea...What type of efficiency do you get from that?

Does anyone use the sparge arm that Austin Homebrew supply sells? It seems like an easy thing to make, but not sure how good these things work.

Depending upon my crush, I hover in the low 80s on efficiency when modified fly sparging in the 10-gallon MLT. My batch sparges in the 17-gallon MLT are in the high 70s.

Here's a pic of mine. It's a 10 gallon cooler a friend gave me. I got the ball valve from Austin homebrew supply. Then I use a SS braid for draining. Attached to the lid is a coil of copper tubing with holes drilled in it for Sparging.

I just use a pitcher! LOL When I start my run off, I begin pouring water over the grain bed, first over a wooden spoon to spread it out... once there is about an inch of water over the bed, I begin speeding the process until I get all the water in. Depending on how big a hurry I am in, I do this in 5-10 minutes. Water in.. running off... no worries.

It is a commonly held fallacy that you have to sprinkle the water in continuously. That works, of course, but it isn't necessary. I have used this method since '89 with great results... both at home and at the commercial level. Ok, commercial scale the process of introducing the sparge water is different, but still it's about getting it in fast and not having to worry about it. I actually learned this method on my first brewing job; Bell's in 1989.

+1. Your goal is just to not disturb the grain bed. You don't want to creat a channel for water to drain without filtering through the grain. By sparge time there's a top blanket of water. I place a piece of Tin foil on top of the water and with my pitcher pour on top of the foil. I'm no pro (far from it) but when I asked the guru at my homebrew store your same question he said there's no need for a fly spargeing if not commercially brewing. I guess based on prior post it's not necessary there either.

The first question that should be asked is what sparging method do you plan to use. If it's batch sparging, there is no device necessary. You deliver the sparge water in any way you want, even dumping.

The question of how you want to sparge actually directs the bottom separation medium even more than the sparge delivery mechanism. Let's start there.

Fly sparge:
Bottom: False bottom or slotted manifold
Top: simple manifold or locline installed through lid.

Batch sparge:
Bottom: mesh braid or slotted manifold
Top: nothing, don't worry about it, just drop the hose in or dump the water in manually

You don't need a "device" in a traditional situation either, as per my previous post. You get the water in on top of the grain bed as quickly as possible and run off as you normally would. It is simple and saves a lot of headache watching levels, etc.
