[0002] Chinese patent [ZL:200620123764.5] discloses a new processing technology of high-grade rice, which is sterilized by ultraviolet light, which not only conforms to food hygiene and safety, but also prolongs the storage period of rice. It is an ideal high-grade rice processing technology The disadvantages of the process are: Ultraviolet radiation disinfection uses high-efficiency ultraviolet radiation to irradiate the air to kill bacteria and viruses. It is easily blocked by objects and has weak penetrating power.

Embodiment Construction
[0006] The process of the present invention is: initial clearing→reclearing→stone removal→into vertical silo→ozone sterilization→electronic metering→magnetic separation→into clean barn→hulling→separation of rice husk→sorting of rice husk→grading of brown rice→ Stone removal→rough cleaning warehouse→electronic metering→spray moistening→multi-stage whitening→white rice grading→hot polishing→cylindrical grading and selection→cool rice→cold polishing→cylindrical grading and selection→first-level color sorting→secondary Color sorting→product warehouse→ozone sterilization→rice blending→ultraviolet irradiation→packaging→finished product warehouse. Compared with the Chinese patent [ZL: 200620123764.5], two ozone sterilization processes are added, and other things remain unchanged, and a higher grade is improved in terms of food safety!
[0007] Special explanation: the change of the three processes of ozone sterilization→rice blending→ultraviolet irradiation is also the scope of pr...

Abstract
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.
Description
technical field [0001] The invention relates to a rice processing method, in particular to a new high-grade rice processing technology. Background technique [0002] Chinese patent [ZL: 200620123764.5] discloses a new processing technology of high-grade rice, which is sterilized by ultraviolet rays, which not only conforms to food hygiene and safety, but also prolongs the storage period of rice. It is an ideal high-grade rice processing technology. The disadvantages of the process are: Ultraviolet radiation disinfection uses high-efficiency ultraviolet radiation to irradiate the air to kill bacteria and viruses. It is easily blocked by objects and has weak penetrating power. Contents of the invention [0003] In order to solve the above problems, the invention discloses a new process for processing high-grade rice. [0004] The technical scheme of the present invention is that the process is: initial clearing → re-clearing → stone removal → vertical silo → ozone ste...
