The invention discloses a novel
processing technology for high-grade rice. The flow path of the novel
processing technology comprises preliminary cleaning, secondary cleaning, stone removing, vertical
silo entering,
ozone disinfection, electronic metering,
magnetic separation, cleaned grain bin entering, husking, rice
hull separation, paddy separating, coarse rice grading, stone removing, cleaned coarse rice bin entering, electronic metering, coarse rice
wetting through mist spray, multistage whitening, rice grading, hot
polishing, cylinder grading selection, rice cooling, cold
polishing, cylinder grading selection,
primary color sorting,
secondary color sorting, product bin entering,
ozone disinfection, rice blending,
ultraviolet irradiation, packaging and finished product bin entering. The
ozone disinfection utilizes a high-pressure discharging mode of an ozone
machine to motivate little air around the
machine into ozone, achieves the disinfection purpose by means of oxidation, belongs to
chemical disinfection modes, can disinfect various microbes such as
bacteria, viruses and funguses, and is not influenced by object blocking, and disinfection effect is good compared with
ultraviolet irradiation disinfection.
