Are you saying that that you use the bucket with a hop bag (in the pic) as a way to filter the hops before you run it through the plate chiller? Or is that bucket what you boil in?
I guess it's not that clear,
this is a fairly widely used hop filter used for whole leaf hops (in the UK)
they are great for whole leaf hops as they hold back the bulk while the hops themselves form a filter holding back most but not all of the finer particulate. (normally this doesn't matter if you are using an immersion or cfc).
All I have done is stick a muslin hop bag over the the filter ie the filter is now inside the bag.
this holds back all the hop seeds and fine particulate which might have got through the original filter which is only some copper tube with loads of holes in. The hop bag is held in place with copper wire.
The picture you can see with the two kettle elements with a hop bag secured around the copper hop strainer is the boiler I use for boiling the wort. The finer mesh of the muslin holds back the hops but without actually restricting them.
btw I know those hop bags a big, but they aren't held open in any way so they wont necessarily fill the entire volume of the boiler. Even the bags I mention later on which have the neck secured around the boiler restrict the movement of the hops to an extent (it happens to be shown in a fermenter in the picture shown but it's the same principal)
