Abstract

The invention discloses a processing technology for rice with the long storage life and the low broken rice rate. The technology comprises the steps that impurities in picked unhusked rice are removed, indoor temperature air drying is performed, hot air drying is performed under the stirring state, and preprocessed rice is obtained; Arabic gum and water are mixed, stirred and added into a single-walled nanotube for ultrasonic concussion, vacuum drying is performed, the preprocessed rice is added and mixed to be uniform, the stirring temperature is 5-10 DEG C, the mixture is fed into steam to be heated and fed into a rice husking machine to be husked, husked rice separation is performed, and husked rice is obtained; the husked rice is cooled to the indoor temperature, polishing, color sorting and classification are performed to obtain the rice with the long storage life and the low broken rice rate. The rice is low in broken rice rate, low in water content, long in storage life and quite high in economic benefit.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a processing technology for rice with long shelf life and low broken rice rate. Background technique [0002] At present, in the rice processing technology, the raw grain is basically harvested by machine, and farmers basically do not over-process the grain, resulting in mixed raw grain, more impurities, and uneven moisture content, which brings great difficulties to rice processing. , after husking and rice milling, it is sent to a polishing machine for polishing, resulting in an unclean appearance and a high rate of crushing, and a low rate of finished rice. Also, due to the high moisture content of the rice, the shelf life is shortened. In addition, consumers' ideas continue to Increase the attention to the shelf life and broken rice rate of rice. The currently processed rice cannot meet the needs of consumers. Contents of the invention [0003] The invention propos...
