I am wondering if anyone has tried filter pressing their concentrate. If you concentrate high, say to 15 Brix or more, might it be helpful at all to filter press that concentrated sap? I'm thinking of two benefits. 1) Being able to clean your pans, steamaway, etc. less often. 2) Change your syrup filter press papers less often. I was thinking that filtering your concentrate could remove some or even most of the niter that is in sap. Or would this not work because niter and other 'free' material is only able to be filtered after it has been boiled for some time. In my mind, you just run concentrate through the filter press and then send it into the evaporator. Anyone tried it?
