Stainless False Bottom

[Andyd]

Re: having the tap above the false bottom...

I should have also posted a picture of the bottom. I have a brass fitting on the underside that draws the liquid from the bottom of the tun. As was pointed out by someone, as long as your outlet is below the bottom of the tun, you'll get nearly everything out of this baby!

Thanks for the advice. Its going to be a herms system so it doesnt matter if the first runnings are cloudy, it will be re-cirulating the whole time and so by the time i sparge the runnings should be fairly clear.

What is wedge wire?

I have some fine, woven mesh but that is flimsy and would need a really well supporting frame to hold it.

The mash will be about as deep as it is wide because ill only be doing ~23L batche4s still.

Do a google on wedge wire,plenty of oz suppliers

i've had a lot of troubles with stuck sparges lately especially since i have gone to a herms system, so the s/s false bottom is the way i'm going next. This is hopefully my first attempt at a false bottom. It is a 2mm thick piece of s/s that has been laser cut with a series of 1.8mm slots cut into it. The plan is to have the wort drain from the lowest point of the tun, and have a threaded rod protrude into the centre of the false bottom with a locknut to hold it into place.
I'll probably will make increase in diameter of about 50mm for the final product.
Anyhow this is it.....

That FB really looks the biz. Sounds like you're on the right track. :beerbang:

From memory Greg Noonan advocates a similar slot configuration in New Brewing Lager Beer.

I am using a similar thing for my new 150L brewery. Its pretty solid stuff - my arms are still aching from cutting the ****** to shape with a grinder. (only did it yesterday...)

Excuse the crappy mobile phone camera photo...

I've been using this SS bottom that I got from G&G since I started AG brewing, it's been great. I did modify it by removing the brass hose fitting and replacing it with a brass stopper because I have my wort outlet at the base of my mash tun.

I have removed the base of my 40 litre S/S urn which I am using as a mash tun
(and also as a bioler) and made a false bottom out of it. It fits perfectly inside the kettle.

Looks like you've drilled all those holes. Must have taken you a while.
Looks real good too.

I had it made up by one of my customers who does laser cutting. I have no idea what it would actually cost to have made if i had to pay for it.....

Whenever we've looked at getting screening panels laser cut for work, the laser cost becomes prohibitive. The time for the laser to cut a hole/slot travel and start cutting the next hole/slot just takes too long compared to a machine custom made for welding strands of wire together.
I know of some companies within the industry; Screenex, Melwire, Johnsons Screens. Don't know how you'd go about approaching them :unsure:

Another option would be to find a fabby with a turret punch, those things are faster than a laser cutter and they may have a punch exactly suiting the hole/slot size you want (saves them taking a second bite at it thus saving you dollars)

Just somre more options

I haven't yet decided whether to go for a false bottom or just opt for the wire braid.

Turret punching is definetly to go for this kind of work if your making more than just one or two units. But for the ease of design changes, and the speed of machine setup for a single f/b, laser wins hands down.
I considered wire, but i like the strength of s/s plate, plus i has access to a laser.

Yes, It took me three days, couple of hours a day, and 17 pots of homebrew.
I am pleased with the results myself.

Thanks.
