Mash tun SS mesh tube drain.

[Simon David kelly]

Hi,

Planning the tun drain using SS mesh tube. However I'm unsure how long it needs to be. I was thinking of coiling about a meter on the bottom, but would the adversly affect the flow of liquid throught the grain bed?

Anyone tried this sort of coil idea before?

The one Jo made for me is just circular, probably just over half a meter long. Works great too. But I'd say it all depends on the size and shape of your mash tun.

I believe a few people have tried it / use it, and I am sure there are a few posts including photos on here explaining how to do it, or ways it's been done. (Yep found the photos)

Nice.

How's the flow on yours? Do you find you get a good extraction rate with it how it is?

[James P]

With the tap fully open I can run 6~8 litres a minute. For a long time the extraction was low due to running off way too quickly, efficiency in the low 60's. Slowing run off to between 1 ~ 3 litres a minute can produce an efficiency in the mid to late 80s.

I think my ring is a touch smaller than the "best" flow rate/ coverage from Palmers HTB designs.

I might try a two ring version of yours with a flow for a slow run off and see what happens.

I mat even get all experimental and solder up a few styles :o)

[James P]

Yeah I had originally thought of a double ring, and for all I know it probably has it's advantages. I'm guessing that would be similar to Nicks one that he got from Liberty.

Where do you guys get your SS mesh tubing?

[James P]

Your local decent hardware / plumbing supply store that stocks them. Mine was Mitre10, but I understand all the ones in Wellington are in receivership now.....

May be a stupid question, but what is it normally used for?

[James P]

It's a water hose wrapped in stainless braid.... like from the tap to the toilet cistern to make it look nicer...

You need to make sure you get the stainless steel and not the stainless coated plastic. Get it home, cut the attachments off the ends, pull the hose out of the braid, presto.

Cheers! I thought that was the case but wanted to make sure before I went and bought some from where ever.
