Research on the Milled Rice Yield of Long Grain Paddy Rice Varieties Measured by Different Instruments

稻谷出米率对于稻谷的加工品质具有非常重要的意义，但是目前对于稻谷出米率的测定，各研究者使用的仪器不一致，不同的仪器测定原理、同一型号仪器不同的测定参数，得到的出米率测定值是不一样的，本文以10个不同品种的长粒型稻谷为研究对象，使用目前市面上主流的三种型号精米机(JNM-III型实验碾米机、BLH-GML60精米一体机、JDMC-110垄碾一体机)测定稻谷的出米率，结果以出米率、整精米率和精米留皮度进行综合判断，推荐使用JNM-III型实验碾米机型号的碾米机进行出米率的测定，该型号仪器测定的整精米率较高、出米率较高且仪器性能稳定，该仪器的最佳仪器参数条件为：稻谷质量21.00 g，碾米时间40 s。The milled rice yield is of great significance for the processing quality of rice. However, at present, the instruments used by researchers for the determination of milled rice yield are not consistent. Different instrument measurement principles and different measurement parameters of the same instrument model will result in different measured values of milled rice yield. This paper takes 10 different varieties of long grain paddy rice as the research object, and uses three mainstream models of milled rice machines (JNM-III experimental rice mill BLH-GML60 all-in-one milled rice machine and JDMC-110 all-in-one ridge milling machine) were used to determine the milled rice yield. The results were comprehensively judged by the milled rice yield, the whole milled rice rate and the husk retention of milled rice. It is recommended that the rice mill of the JNM-III experimental rice mill model be used to determine the milled rice yield. The whole milled rice rate measured by this model of instrument is higher, the milled rice yield is higher, and the instrument performance is stable. The best instrument parameters of this instrument are: the rice mass is 21.00 g, and the milling time is 40 s.
