Grain left on the wort after pulling pipe

Unread postby leosardinha » Mon Jun 16, 2014 12:57 pm

Has anyone experienced this?

I note that this occurrs specially when I use the limit of the malt pipe.

When I remove the protein that coagulates pre-boil, my strainer comes out full of tiny grains.

Maybe some small grains escape through the little bottom hole?

Just a thought. I can't see any other way, though...

Maybe it can be this + the fact that I squeeze the filter plate and is ends up pushing the grain through the lower plate.

I think next time I will lock lock it gently.

I've had a lot of grain in the boil before.
I believe the issue is as Niels suggests - gets through the bottom hole.
I have a pulley set up. For a while I was lifting straight up and off the centre rod, and attaching a hook in such a way that the malt pipe sits on an angle to drain more wort from the grain (this was my theory anyway). I think the straight lift was letting grain fall down the hollow left by the rod.
Other times I've lifted onto the U shaped rest provided with the BM which lets the malt pipe sit at such a level where the rod is still blocking the hole. Then while sparging, the grain fills the void left by the rod, and the bed seems to become more stable around the hole, letting less or no grain to drop through.

Chilli,

I managed with being more gentle with the locking of the malt pipe and the initial sit.

Also when I started using my pulley system to lift the malt pipe, as it is standing straight as Dan says, it minimizes the grain escape.

Cheers lads,

When do you guys put the malt pipe in? before the water?

After. I like to be precise with my volume measurements and the malt pipe adds 2-300mL to the strike volume.
As soon as I have my volumes I'll put the pipe in then start heating. But all volume measurements are taken without the pipe in.

Dan, understood.
I just think you get a better seal putting the malt pipe in before the water.
Dry gasket against a dry BM floor seals better , no?

Shouldn't make any difference to the seal. How tight you lock the wingnut down will determine how tight the seal is
