Recirculating

[dijital]

im using a birko boiler for sparging my grain as i can keep the temp at a constant 62 - 66 degrees during sparging but ive just bought a small pump and im planning to recirculate the wort from the copper into a homemade sparging arm throughout the process and im just wondering if anyone can see any problems with this method of brewing???? :huh:

You would want to be sparging at around 80 - 90 degrees to stop enzyme activity.

Those temps are fine for recirculating though.

Only issue I would be concerned with is if the pump is food grade safe?

You dont want to be leaching plastics, etc into your precious wort.

Ideally you want to be sparging at 78c. If the pump parts are food grade & can handle hot liquids, all should be good.

I would recirculate the wort just through silicon hose back into the mash tun to get clear runnings.
I wouldn't put it through the sparge arm as you will aerate it at high temps and block all the holes up in your sparge arm.
Put the hose under the water level in you mash tun and away you go.
You'll only need a minute or so.
You'll want your sparge water at 78 - 80 degrees.

a few pics and some discussion on recirculation here http://www.aussiehomebrewer.com/forum//ind...3423&st=140

keep the flow rate from the pump at a fairly slow rate and the holes in your return at about 5 or 6 mm and you won't have a problem with blocking
