Beer & Wine Plate Filter

[StAnthonyB]

Has anyone here used the beer and wine plate filters?

If so have you been successful in filtering after carbonation?

I would imagine it would require using two corny kegs (one pressurized to match the pressure of the filled keg) and the plate filter and a bottle of co2 or nitrogen and placed in a chest freezer in order to maintain the original desired carbonation level.

Perhaps, any use of co2 could be drawn off of a captured co2/spunding valve setup.

In practice for me the finished product would be for real ale (gravity drawn) purposes, so the use of co2 or nitrogen is only to bleed and maintain about 1 psi (or maybe just over).

High,
I have a plate filter, that I use for my wine filtration.
I can stack up to 12 Plates (40cmx40cm) for a total volume of about 600litres/hour.
I`ve also used it for beer.
The filter does remove a lot of carbonation, if not used with counter pressure.
Since most manufacturers of filter sheet recommend a pressure difference of 0,5bar(7psi) between in- and output, I strongly recommend the beer to be filtered to be as cold as you can possibly get it.
This poses a problem if you want to steam sterilize your filter, cause this will heat up the housing, plates and sheets and therefore the beer.
So you`re stuck with chemical sterilisation, which leaves a lot of beer(Vorlauf) wasted or you have to pump icewater through it before starting.
What I do, I filter the hot wort before aeration and adding the yeast.
I do not use sterile sheets , fine being max, mostly medium though.
Because most of the solids have been removed, it`s not a bad idea to add DAP to your wort for increased yeast health.
I ferment in kegs using a shortened spear.
Before I bottle (counter pressure) I chill the keg down as cold as I can get it and leave it sit for a week to settle out as much of the yeast that is still in suspension, as possible.
Actually it is a lot of work.
To get a really clear beer, I will use extracts with just a little grain for increased body.
Would be glad to hear other opinions

I got ya'

I was reading about the canister filters. From what I can tell those can be used to maintain carbonation if the beer has been brought down below 40F and using with gravity and counterpressure.

With gravity you won`t be able to filter into a counter pressurised vessel, be it bottle or keg.

That's interesting and thanks for the tip.

I think it is something I'll have to look into considering the Dave Miller homebrew book. I wonder if it is indeed possible. We may just be getting the terms of the technique incorrect.
