超声波红枣清洗机工作参数优化

Working parameters optimization of ultrasonic cleaning machine for jujube

为了提高制干红枣清洗的质量,设计制造了以超声波为清洗动力的红枣清洗机。分析了超声波清洗红枣机理;以预备试验为基础,确定了清洗机的参数及范围,通过超声波对制干红枣的清洗正交试验,对试验数据进行极差与方差分析表明,当清洗机超声波功率550W,清洗水温60℃,清洗时间4min时,清洗效果最好。在该条件下进行清洗制干红枣原料,洗净率大于96.2%,破损率为0.8%。研究结果可为红枣制干加工企业清洗技术提供参考。

In order to improve the cleaning effect of the dried jujube during cleaning process, the jujube cleaning machine was designed and manufactured by using ultrasonic as power. On the basis of pretests, the parameters scope of the cleaning machine was determined. Through orthogonal test of ultrasonic cleaning to dried jujube, the range analysis and square analysis were carried out on the test data. Under the experiment condition of power 550 w, temperature 60~C and cleaning time 4 min, the results showed the best cleaning effect with cleaning rate of above 96.2%, breakage rate of 0.8%. The experiment results can provide a scientific and technical basis for jujube dried enterprises.
