Prominent quality problems of key components of small rice mills
The investigation found that the poor quality of the key parts of the rice milling machine is the most intense problem reported by users. Fifteen of the 30 users surveyed raised parts quality issues, accounting for 50% of the total number of surveys. The quality of the key components rice grading screen and rubber rollers is the focus of the complaint.
For example, according to a grain processing point in Wuming County, Guangxi, the screens of his rice hulling and milling machine can work for 7-8 hours, and the life of the rubber roller is less than one month. The user buys parts in the agricultural machinery store, the screen is about 5 yuan/piece, and the rubber roller is about 300 yuan/pair. Compared with the smiling profit of food processing, the cost of replacing parts is not small.
When investigators observed the sieve, they found that the sieve was not heat-treated in accordance with the standard, and the quality could not be guaranteed. The replaced rubber roller was also very resistant to wear and had a pungent odor. It was obviously made of inferior rubber. In the survey, similar problems are very common.
