<P>PROBLEM TO BE SOLVED: To provide a method for producing wash-free rice by which rice bran layers are relatively easily removed without lowering in quality, and cooling equipment can be minimized. <P>SOLUTION: This method for producing wash-free rice comprises the following process: a process of charging unpolished rice having a flavor layer at its husk part and a rice bran layer covering the surface of the flavor layer into a washing tank 13 together with a predetermined amount of water; a process of converting the rice bran layer to a viscous fluid-state coating film through stirring the brown rice in the washing tank together with the water to make the rice bran layer absorb the water; a process of peeling the viscous fluid-state coating film from the surface of the brown rice through supplying a predetermined amount of liquid carbon dioxide to the washing tank from a liquid tank 11 followed by stirring the liquid carbon dioxide in the washing tank; a process of leaving flavor layer-exposed polished rice in the washing tank through discharging the peeled viscous-state coating film from the washing tank together with the water and the liquid carbon dioxide; and a process of obtaining wash-free rice through taking the polished rice from the washing tank to dry it. In the method, the viscous fluid-state coating film is removed from the water and the liquid carbon dioxide discharged from the washing tank, and the water and dissolved matters are separately removed to recover the remaining clean liquid carbon dioxide into the liquid tank 11. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
