Abstract:
1. An apparatus for simultaneously suspending, agitating, and entraining a compost nutrient water culture, comprising: a beaker having a predetermined cross-sectional shape for containing said compost nutrient water culture, an open top and an open bottom; a lid and strainer covering said open top; a vibrating perforated elastic membrane transversely covering the open bottom of said beaker; a holder for compression sealing of said membrane on the open bottom of said beaker; a base containing an air pump, wherein the holder mates with the base so as to provide fluid communication between the air pump and the bottom side of said membrane and wherein air provided by said air pump against said bottom of said membrane, overcomes hydrostatic pressure of said compost nutrient water in said beaker thereby sparging enough air through said perforated membrane and into said compost nutrient water culture to maintain 6 mg of oxygen per liter through out a brewing cycle; and said base and holder including means for quick connect/disconnect of said fluid communication between said air pump and said bottom side of said membrane.
