TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The step of dehulling the barley comprises removing hull from the barley using at least one of a dehulling device, a hammer mill, a roller mill, a disc mill, a ball mill, a pin mill, a shaker table and an aspiration table. The mechanical separation device comprises a multi-zoned screening apparatus, a paddle screen, a filtration centrifuge and/or a pressure screen.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further comprises: separating the slurry to create a suspended large-particles stream and a liquids and fine-suspended particles stream using a mechanical separation device; shearing a portion of the suspended large-particles stream to create ground particles; heating the ground particles with other portion of the suspended large particles stream and with water in a tank to create a lower-solids mixture; adding beta -glucanase to the milled barley berries with the alpha -amylase and the water in the slurry tank to create the slurry; adding endogulcanase to the milled barley berries with the alpha -amylase and the water in the slurry tank to create the slurry; adding beta -glucosidase to the mash with the microorganism in the fermentation tank to produce the fermentation product; adding cellobioydrolase to the mash with the microorganism in the fermentation tank to produce the fermentation product; milling wheat to be added as another feedstock, where the milled wheat is separated into food grade protein from wheat starch; and adding the wheat starch to the milled barley berries, the alpha -amylase and the water in the slurry tank to create the slurry. The lower-solids stream in the tank is heated to a temperature of lower than 90 degrees C (363 K) to remove starch; or is heated to a temperature of higher than 100 degrees C (373 K) to leach oil. The method-1 further comprises: receiving a portion of the first large-particles stream; shearing particles in the portion of the first large-particles stream using a shearing device; sending the particles sheared to be combined with the water and the first large-particles stream in the tank to create the lower-solids stream; increasing an ethanol yield to 1-3%; increasing an oil recovery to 10-50%; adding more water to the second large-particles stream in another tank to create another lower-solids stream; heating the another lower-solids stream in the another tank; filtering a third large-particles stream from a third liquid stream containing small particles of the process stream using a third mechanical separation device; and receiving the third large-particles stream to further separate insolubles from liquids in the third large-particles stream using a dewatering device. The step of shearing the particles comprises using a disc mill, an impact mill, a roller mill, a centrifugal pump, a venturi jet and/or a hydroheater. The first mechanical separation device produces a solids content of 18%. The first mechanical separation device and the second mechanical separation device use a counter-flow wash process.
