THE STUDY OF THE EFFECTS OF RICE QUALITY ON THE EFFICIENCY OF ITS PROCESSING
There were presented comparative analysis' results of criteria rice quality used in Russian and international standards. Also there were shown summarized statistical analysis' results of rice quality that was processed in 2013-2016 on rice mill plant at “Krasnodarzernoprodukt” Company. The purpose of research was to find factors that had influence on combining rice bulk effectiveness on specialized elevator. It was found that diapason of rice moisture content was quite small. Red rice content was ranging from 1.08 to 5.10 % with confidence interval of 1.98-2.56 % that is evidence of small amounts of rice bulks with extreme high or low red rice content. Broken rice content varied in the wide range from 3.43 to 9.26 % with confidence interval from 5.84 to 7.26 % that shows necessity in length grading procedure applying for broken kernels removing at the elevator unit. Grain impurities content exceeded basic norm in 3-4 times that is a sign of low efficiency in the process of separation. During the treatment of rice bulks combined at the grain cleaning unit of rice plant broken rice cereals output varied in wide range from 3 to 9 % during single shift that is seems to be connected with kernels cracking increasing and rice moisture decreasing. Moreover, rice bran output also varied in a wide diapason from 10.2 to 17.0 % that could be explained by big swing in rice moisture, glassy texture and cracking of rice grains. According to our research it was investigated that current rice quality control system that is a base instrument of rice bulks forming for further processing is not quite efficient and as a result there should be created and implemented new methods and technical devices for quick and proper grain control that could assure stable technological regimes at different stages of rice treatment process and that would provide the best quality and the biggest output of rice cereals
