Drez77,

Can you detail the false botton/screen a bit? Does it just sit at the bottom? Can you show the outlet port from an inside view?

Thanks!

I have the hop back from B3. Edit: Fitted with tri-clamp fittings from Sabco. WARNING! the fittings alone cost more than the hopback itself.

Bought mainly to be used as a plate chiller pre-filter since I tire of the paint strainer filter/hop stopper/scrubby ineffectiveness with high hop loads and break filtering. But, I also grow my own hops and what a better way to put those to use than in a hopback eh?

Anyway, my filter method is to load the hopback with rice hulls. A 55 pound bag of rice hulls cost me $35 so, no need to skimp. Over that I place a stainless steel vegetable steamer basket. the basket weighs down the rice hull enough to creat a tight filter bed without sacrifice to flow. Without the basket the wort just drills through the rice hulls as they float.

Above the basket I can still add an ounce of hops should I choose to.

The result. All pellet hops and hot break trub are trapped in the rice hull filter medium and keep well away from my plate chiller therefore allowing me to dose my kettle free-nilly with whatever medium i choose.

Oh. And it makes a damned fine hopback too.

No. Not of the hop back in service as a pre-filter. But the post was about a thousand words so that should paint the image.

Glad that worked out for you. I haven't been to the BM forum in a while.

No problems with haze from the rice hulls I take it? I would have thought not, it should be mostly beta glucans and not real soluble. I'm thinking about adding a hop back (mostly for, you know, hops) and this would be a way to keep the system the same if I don't want any hop character.

Nope. No issues on the second and foloowing runs so far. Just clean clear wort into and out of the plate chiller. I recirculate through the HB with the chill wizard to bring the batch temp down quickly and trap as much trub as possible. Yes, I realize I am also trapping cold break that is benificial to yeast but I usually dose the fermenter with some nutrient to be overly safe.

i've been thinking about adding a hopback to my system, but am curious about how much of a difference it makes vs only FO hops. is the effect different or just more efficient? in other words, could you just replace the hopback hops with more FO hops, or is it just not the same? thanks!

GilaMinumBeer,

Are you rinsing the hulls before putting them in the hopback? They are so dusty/dirty without rinsing first.

Here's my hop back, it's a modified asparagus steamer:





I used it as a grant at first but it wasn't big enough for 12 gallon batches. I modified a corny to use as a grant instead:
