Blichmann's boil kettle filtration unit boasts up to 95% efficiency on pellet hops and is impervious to plugging.
Traditional screen filters draw from the bottom of the pot — immediately sucking all pellet hops and fine break material into the screen, where they plug. In Blichmann Engineering's HopBlocker™, preferential flow leaves settled fine break material (hops and trub) undisturbed at the bottom of the pot while draining the majority of the wort through a coarse filter from the top down. When the wort level is just a couple of inches from the bottom of the pot, the fine filter element is then exposed by lifting the shield, and the remainder of the wort is filtered. It's an intuitive design that allows the fine filter to work only on a small portion of the wort, not all of it. The HopBlocker™will filter up to 95 percent of the break material and hops from your wort without plugging. While it is designed specifically to complement Blichmann Engineering's BoilerMaker™pots, the HopBlocker™can be installed in any manufacturer's pot or keg, and instructions are provided.
PLEASE NOTE: The HopBlocker is designed for use with pellet hops only. Whole/loose hops will plug the unit. While using whole hops, or a mix of whole and pellet hops, you must bag your whole hops in a large muslin grain bag. This will not effect the utilization rate and will result in significantly less wort loss.
