滚筒式脱水蔬菜干燥机最佳滚筒转速计算分析研究

Optimal Roller Speed of Drum-type Dehydrated Vegetable Drier

蔬菜通过脱水干燥,可降低含水率,使脱水后的蔬菜能够在常温下较久保存,且便于运输和携带。大多数小型加工厂生产脱水蔬菜,其干燥过程采用滚筒式干燥机,滚筒的转速是直接影响脱水蔬菜质量的重要因素。通过对脱水蔬菜在滚筒内受力情况和运动轨迹分析,研究出滚筒的最佳转速和相关参数。

Vegetables can reduce water content after dehydration,which is benefit for long-term preservation,transportation as well as carryover at normal temperature after dehydration.Drum-type drier has been widely employed in some small processing plants to produce dehydrated vegetables.However,the roller speed is one of the key factors that affect the quality of dehydrated vegetables.In this study,stress condition and movement track of vegetables in drum were analyzed to acquire the optimal roller speed and corresponding parameters,which will provide theoretical basis to improve the quality of dehydrated vegetables.
