Processing method capable of reducing broken rice rate of rice

Abstract

The invention discloses a processing method capable of reducing broken rice rate of rice. The processing method comprises steps of drying, impurity removal, husking, primary rice milling, wetting, drying, secondary rice milling, polishing, color sorting and classification. During polishing, sodium citrate solution is adopted as an additive for primary polishing treatment, then a sodium citrate andhydrogen peroxide mixed solution is used as an additive for secondary polishing treatment, so that starch on the surface of rice can be promoted to be gelatinized to form colloidal films, meanwhile,the starch layer structure on the surface of unpolished rice can be more compact, and the surface finish of the rice is higher.

Description

technical field [0001] The invention relates to the field of rice processing. Background technique [0002] Rice is one of the most commonly eaten staple foods. Rice processing in a broad sense refers to the comprehensive processing process from rice husking to polished rice products. The rice processing process basically includes impurity removal, rice milling, polishing, color sorting, grading and packaging. [0003] In the actual production process, the broken rice rate in the rice obtained by the rice processing technology accounts for 15-30%. Due to the following two reasons, the broken rice rate will increase: the first is the various treatments before the rice processing, including the rice The state of harvesting, during the process of threshing, tumbling, loading and unloading machine transportation, the rice is crushed by mechanical impact; the second is the technical performance and operation management level of rice processing machinery and equipment. When sol...
