PURPOSE:To solve problems, such as the yield of pestling, rice hulling rate and surface rubbing, and to maintain an adequate moisture so as to obtain the rice of a good taste by subjecting the harvested rice to an intermediate drying at the moisture between 22 to 17%, then to a finish drying just before the rice hulling. CONSTITUTION:The harvested rice is dried gently in the range of 22 to 17% moisture in intermediate drying stages 10, 11 but even if the drying is by fire power, the temp. rising speed of the hull is low and since the rice is maintained at the high moisture, the overdrying does not rise. The uniformization of the moisture is attained and the finish drying 14 of the ensuing stage is facilitated if the dehumidification drying is adopted for the intermediate drying. The harvested rice which is subjected to this intermediate dying is then subjected to the finish drying just prior to the rice hulling stage 6. The moisture conditions of the rice just prior to the rice hulling are exactly adjusted in this way, by which the yield of the pestling is improved, the rice hulling rate is improved, the surface rubbing is decreased and the taste is maintained. In addition, the dealing with all kinds of treatment forms is possible by the combination of the dehumidification drying and fire power drying. |
