Abstract:
A process for parboiling paddy rice or cargo rice, comprising steeping said rice in water at a temperature lower than 70Â° C. under such conditions and for such a time that, after drainage or spin-drying, steeped rice is obtained having a moisture content by weight greater than 31%, then in carrying out a gelatinization of the steeped rice by heating it to a temperature greater than 130Â° C. while maintaining the moisture thereof at a content by weight greater than 20% for a sufficient period to obtain core-gelatinized rice, characterized in that said process includes carrying out gelatinization by causing the steeped rice to pass continuously into an enclosure so as to limit, by virtue of the equilibrium which is established within the enclosure between the moisture content of the rice which is undergoing gelatinization and the moisture content of the gaseous atmosphere of the enclosure, the quantity of vapor emitted from the rice during gelatinization, in order to maintain the moisture content by weight of the rice in the course of gelatinization at a value greater than 20%, and by heating the steeped rice in the enclosure essentially by conduction so as not to increase the moisture content by weight of the gelatinized rice appreciably.
