In order to understand the quality of rice mills in China, the National Grain and Oil Processing Machinery Quality Supervision and Inspection Center has carried out the operation of 30 rice mill users in Guangxi, Hunan, Shangdong, Sichuan and Liaoning provinces. The quality and safety survey of 30 rice milling machine users is as follows:
1.如何使用培训。只有3名用户表示在使用前接受过公司培训，占调查总数的10%。其余用户均接受了培训。
