Method to pre-cook germinated whole grains of brown rice, coarse cereals and legumes comprising: - sprouting by soaking for example in tanks, and in circular compartments with turner equipment. - stopping the sprouting when the sprouts begin to form in order to avoid malting process, - dripping and adding to the grain a solution containing 0.1-0-8% preferably 0.2%, NaCl, - tempering the grains without moisture or temperature loss; - heating the core of the grains in a microwave device at a temperature about 70-75°C for 1-5 minutes, - first drying in a fluid bed dryer to reduce the moist content (MC) from about 30-35% to 16% MC, - turbo cleaning at 16% MC, wherein the grains are turbo cleaned passing through a turbo device configured to eliminate only the cells close to the embryo which contain the phytates already weakened by the sprouting, the turbo device being a vertical conical turbo cleaning machine comprising: - a sequence of whitening discs divided by aeration rings , sieves provided on the inner wall of the machine, wherein the whitening discs are smooth disks in plastic material, - a bran aspiration 10 preferably working at 0.24-0.27 bar (180-200 mm Hg) in order to suck the bran, - a main drive motor connected to an inverter in order to regulate rotational speed of the whitening discs , - a ventilator connected to an air pipe and an air inlet , the ventilator , the air pipe and the air inlet being configured to supply high pressure and volume whereby creating high turbulence in the processing chamber, - heating the grains at 65° C preferably in an Archimede type screw conveyor adding steam, - pressing the grains in a compression or pressing unit. - sprouting by soaking for example in tanks, and in circular compartments with turner equipment. - stopping the sprouting when the sprouts begin to form in order to avoid malting process, - dripping and adding to the grain a solution containing 0.1-0-8% preferably 0.2%, NaCl, - tempering the grains without moisture or temperature loss; - heating the core of the grains in a microwave device at a temperature about 70-75°C for 1-5 minutes, - first drying in a fluid bed dryer to reduce the moist content (MC) from about 30-35% to 16% MC, - turbo cleaning at 16% MC, wherein the grains are turbo cleaned passing through a turbo device configured to eliminate only the cells close to the embryo which contain the phytates already weakened by the sprouting, the turbo device being a vertical conical turbo cleaning machine comprising: - a sequence of whitening discs divided by aeration rings , sieves provided on the inner wall of the machine, wherein the whitening discs are smooth disks in plastic material, - a bran aspiration 10 preferably working at 0.24-0.27 bar (180-200 mm Hg) in order to suck the bran, - a main drive motor connected to an inverter in order to regulate rotational speed of the whitening discs , - a ventilator connected to an air pipe and an air inlet , the ventilator , the air pipe and the air inlet being configured to supply high pressure and volume whereby creating high turbulence in the processing chamber, - a sequence of whitening discs divided by aeration rings , sieves provided on the inner wall of the machine, wherein the whitening discs are smooth disks in plastic material, - a bran aspiration 10 preferably working at 0.24-0.27 bar (180-200 mm Hg) in order to suck the bran, - a main drive motor connected to an inverter in order to regulate rotational speed of the whitening discs , - a ventilator connected to an air pipe and an air inlet , the ventilator , the air pipe and the air inlet being configured to supply high pressure and volume whereby creating high turbulence in the processing chamber, - heating the grains at 65° C preferably in an Archimede type screw conveyor adding steam, - pressing the grains in a compression or pressing unit. <EOS>
