domed false bottom/hop filter

[danb]

I have the 12" dome fb in the mash tun and very happy with the performance. I am thinking of getting the 9" for my boiler. At the moment I have a short piece of drilled copper and while it works the run off is a bit slow. Plus the fb is stainless.
Any body use one as a hop filter?
Thanks

While the small holes needed for a grain filter work well, I don't think they would act as a hop stopper, it would be prone to clogging.
Ideally 4.5/5mm holes are needed for hops and plenty of them.

That might be why my copper one has a slow run off, it has 3mm holes.

You may need your false bottom for pelleted hops, I don't know as I've never used them.

I have a copper hop strainer with 2mm holes, i hop light but have no issues . Maybe you just need a longer pipe with plenty more holes . You don't want too much crap getting through .

If you re-circ the 1st 0.5 ltrs no more crap gets through.

Decided to try something similar. A pound land tray with a lot of 2.5mm holes. Going to use a tank connector in the centre with an elbow and pipe to the tap.
There's more holes than the copper pipe I have been using so run off should be quicker. My last batch took about 40 minutes to run off.

I have a 12 inch fb in both mash tun and boiler, both with holes and they work fantastic. I hop a lot.
They are the ones from the homebrew company.

I think there's no reason the one I'm making won't work then. I am going to drill more holes on top and round the side then give it a go. :thumb:

Going to get the fittings in the morning and drill more holes. Should be between 350 and 400 3mm holes.

Done and only 200ml dead space.

Worked great today with 110g hops. Loads faster run off. :thumb:

Glad to hear it worked Dan Bit late replying but I used to use a Morebeer domed screen in the copper with no issues, however like already mentioned pellets will require covering it top and bottom with mesh.

I've not bothered with pellets yet so I'll stick with it until Ineed to change it. :thumb:
