i recirculate through a mash tun, but i need to have a particular size grain mill so the husks form a filter bed.
the theory seemed to make sense to me, but maybe one of our experienced chaps could throw some light on it.
You can end up with a stuck sparge if you mill too fine .. ends up like concrete..
you can still mill finer with a bag/basket then if you are using a manifold or a false bottom
Also re the trivet comment I find an upside down colander or sieve works as well
Re circulation helps with a few things
[list=]Helps with a more consistent temp throughout the vessal
Allows liquid that isn't as saturated with sugar to remove more from the grain (hope that makes sense) [/list]
As you are BIAB you are generally not sparging (this will leave sugars behind) and using the whole volume of water at the start, making sure you move the liquid around will help with efficiency
Re malting, ive done it with about 5kg of wheat and it was a pain in the ass, I used a dehydrater to dry it. How are you planning to go?
