The invention discloses a rice process in the technical field of rice processing. The rice process comprises the steps of: impurity removal; dehumidification: paddies are paved in a drying room for drying by a hot air drying method to reach the paddy water content of 12-14%, and the hot air temperature is 35-45 DEG C; primary rice milling: the unshelling rate reaches 60-80%; attachment of water mist on the surfaces of semi-finished products by an atomization method; drying of the semi-finished products by cold air to reach the semi-finished product water content of 12-14%; secondary rice milling; polishing; and color sorting and classification. The paddies are cooled before being suffered from a mechanical effect in each link; compared with traditional airing and direct once high-temperature drying, the dehumdification process alleviates the effect of taking away water in the paddies, and is uniform in heating; compared with a traditional process, the rice process combines wetting and drying procedures, adds the wetting and drying, after wetting, steps, and uses secondary rice milling for largely reducing the rice milling rate; and the same one batch of paddies machined by the method reaches the rice milling rate of below 8%.

The invention relates to the technical field of rice processing, in particular to a processing technology for lowering rice breaking rate. The processing technology for lowering the rice breaking ratecomprises the following steps of one, impurity-removing, wherein unhusked rice harvested is put into an impurity remover, and impurities are removed; two, one-time drying, wherein microwave drying equipment is adopted, the unhusked rice is dried under nitrogen condition until moisture content of the unhusked rice reaches 16-18%, and the unhusked rice is cooled to room temperature; and three, one-time rice-milling, wherein the unhusked rice cooled to the room temperature is put into a rice husking machine so that rice husks are removed, the husking rate reaches 60-80%, and a semi-finished product is obtained. The processing technology for lowering the rice breaking rate has the beneficial effects that by means of a microwave drying manner, drying is conducted through generation of heat byvibration of holistic water molecules rather than through thermal transmission from the outside to the inside; in this way, drying is uniform; the situation that surface of rice grains becomes brittlerapidly because of excessively high temperature, while excessive internal moisture is still reserved is avoided; the surface of the rice grains does not become brittle, and then the probability thatphenomenon of broken rice appears is lowered; moreover, stirring is not needed; the phenomena of broken rice caused by machinery are reduced; and germination of unhusked rice under a microwave condition is guaranteed by the nitrogen atmosphere.
