Processing technology of good-quality rice

Abstract

The invention discloses a processing technology of good-quality rice. The processing technology is characterized by comprising the following steps of impurity removal, drying, one-time rice milling, wetting, drying, two-time rice milling, polishing and color sorting and grading. The processing technology of the good-quality rice has the advantages that in each step, rice is cooled before the rice is about to be subjected to a mechanical effect; compared with traditional airing and direct one-time high-temperature drying for the rice, through a process of drying the rice, the effect of removing moisture in the rice is relieved, and heating is even; in combination with wetting and drying processes, through two-time rice milling, compared with a traditional technology, the wetting step and drying step after wetting are added, the rice milling rate is greatly reduced, and for the rice, processed through the method, in the same batch, the rice milling rate reaches 8% or below.

Description

technical field [0001] The invention relates to a processing technology of high-quality rice. Background technique [0002] Rice is one of the most commonly eaten staple foods. In a broad sense, rice processing refers to the comprehensive processing process from rice shelling 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 at the time of harvesting, during threshing, drying, loading and unloading transportation, etc., the paddy is crushed by mechanical impact; the second is the technological performance of rice processing machinery and equipment and the operation and man...
