ABSTRACT:
The apparatus of the present invention is useful for recycling protein waste and producing fuel from protein waste. Waste is ground by a grinding means and digested by a enzyme digest medium composed of enzymes, preservatives, and inedible egg. The ground proteins are digested with the enzyme in recirculated digest tanks. Fat can be collected from the tank by addition of acid and separation of fat from water with a centrifuge. Alternatively the ground protein and enzyme can be fermented and gas collected from the digest tank in a pressure tank with a compressor. The protein solubles are emulsified, separated from water, and extruded before drying. Either fat or gas can be used to fuel a dryer. The dried proteins are then milled in a hammer mill and screened for uniform size.
