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 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 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.
