Refined rice processing method

Abstract

The invention discloses a refined rice processing method. The refined rice processing method comprises the following steps of rice screening, stone removal, magnetic separation and rice shelling, rice-bran separating, secondary shelling, thickness grading, moisture measurement and drying or atomizing, rice milling and white rice grading, rice cooling, polishing, color sorting, secondary white rice grading and moisture content detection, and packaging. The refined rice processing method comprises a plurality of impurity removal steps, and consequently, the purity of rice is guaranteed, the produced rice is high in purity, and the safety and the processing efficiency in the processing process are guaranteed. In the rice shelling and rice milling steps of the refined rice processing method, the material temperature is strictly controlled so that the material can be always kept in a relative low temperature appropriate environment, and the crack ratio and the broken rice rate can be reduced and the complete particle rate can be increased; the original faint scent of rice is maintained. The refined rice processing method is used for solving the problems of surface damage and uneven polishing in the rice polishing process by controlling the polishing water temperature and the dampening amount; as a result, the surfaces of all the rice grains polished can be kept smooth and clean, and the quality guarantee period of the rice can be prolonged.

Description

technical field [0001] The invention relates to the technical field of rice finishing, in particular to a method for processing refined rice. Background technique [0002] Rice is one of the most important foodstuffs in people's daily life. With the continuous improvement of people's living standards, consumers have higher and higher requirements for the quality of rice, and the requirements for rice quality are not only reflected in quality and taste, The sensory requirements are also getting higher and higher, especially the high-quality, round and crystal-clear rice is more popular among consumers. The quality of high-quality rice depends not only on its origin and variety, but also on the later processing technology. If the raw rice grains with good varieties and good quality do not have good processing technology, their later selling price will be greatly reduced, which will cause huge economic losses to the processing plants. [0003] The existing rice processing meth...

Problems solved by technology

However, due to the different specific operating conditions of each factory, the quality of the rice produced by the above-mentioned method and equipment is also uneven, and the quality of the finished rice cannot be guaranteed, resulting in problems such as a decline in the yield of refined rice and a decline in the utilization rate of raw rice.
