传统老式水稻碾米机采用加工小麦和稻米的设备，应用于玉米整理和谷物清理。随着谷物加工设备在脱粒过程中的广泛应用，谷物中的杂质和边角料更多，传统的完整设备无法在生产中清理干净。边角料与谷物杂质体积和重量相同，传统设备无法清理干净，谷物的清晰度对成品质量影响很大。
The survey found that the poor quality of key components of small and medium-sized complete sets of traditional rice milling machines is the most powerful problem reflected by users. Fifteen of the 30 surveyed users raised component quality issues, accounting for 50% of the total survey. The key components of rice grading screen and rubber roller quality are the focus of complaints.
For example, according to a grain processing point, his family’s sifting and sifting machine screen can work for 7-8 hours, and the life of the rubber roller is less than one month. The user purchases parts in the agricultural machinery store, the screen is about 5 yuan/piece, and the rubber roller is about 300 yuan/pair. Compared to the smile profit of grain processing, there is no small expenditure when replacing parts.
调查中发现，筛网未按标准要求进行热处理，质量无法保证，更换的橡胶辊也非常不耐磨且令人恼火，明显是劣质橡胶制成。类似问题在调查中非常普遍。
因此，仍使用传统水稻碾米机的用户，建议升级谷物加工设备。您可以尝试龙跃机械生产的全套设备。
