Ili kuelewa ubora wa vifuatavyo vya mchele nchini China, Kituo cha Usimamizi na Ukaguzi wa Ubora wa Vifaa vya Kusindika Nafaka na Mafuta kimefanya utafiti wa watumiaji 30 wa vifuatavyo vya mchele katika mikoa ya Guangxi, Hunan, Shangdong, Sichuan na Liaoning. Utafiti wa ubora na usalama wa watumiaji 30 wa mashine za kusaga mchele ni kama ifuatavyo:
1. Jinsi ya kutumia mafunzo. Watumiaji watatu tu waliripoti kuwa walifundishwa na kampuni kabla ya kutumia, wakichukua asilimia 10% ya jumla ya utafiti. Watumiaji wengine walifundishwa.
2. Security protection. Only two user rice mill safety guards were complete, accounting for 6.7% of the total surveyed; 70% of users removed the safety guards, and 23.3% of the users did not have safety guards when they purchased the machine.
3. Safety signs. Only one user with safety signs meeting the standard requirements accounted for 3.3% of the total surveyed; 23.3% of the users reported that the safety signs of the rice milling machine were incomplete or unclear, and 73.3% of the users had no safety signs on the rice mill.
4. Usindikaji wa ubora wa mchele. Kuna watumiaji 8 wanaosindika mchele wenye ubora mzuri, wakichukua asilimia 26.7% ya jumla ya waliofanyiwa utafiti; asilimia 73.3% ya watumiaji wana matatizo ya ubora wa kuwa na grains zaidi na mchele zaidi ndani ya mchele.
5. Ubora wa sehemu. Watumiaji kumi na tano walionyesha ubora wa sehemu, wakichukua asilimia 50% ya jumla ya utafiti. Miongoni mwao, matatizo ya ubora duni na maisha mafupi ya sehemu kuu kama sieve za mchele na magurudumu ya mpira ni ya prominent sana.
