中文摘要：为了寻找甲壳素低耗高效干燥方法,该文在红外干燥条件下,对甲壳素的干燥特性进行了研究。研究结果表明,温度因素对甲壳素的干燥速率影响较大,随着温度的升高,干燥速率增大,而物料的粒度对干燥速率没有显著影响。采用线性回归分析程序,分析比较了不同干燥模型,结果表明,Page模型能较好地描述甲壳素红外干燥过程,可以准确地预测各干燥阶段的干燥速率及含水率。

外文摘要：In order to look for a low-energy-consumption and high-efficiency drying method, the drying characteristics of chitin under infrared ray were studied. The results show that temperature has more obvious influence than granularity on the drying rate of chitin. With the increase of temperature, the drying rate increases. The chitin granularity does not have a significant influence on drying rate. Comparisons of different drying models at different temperatures were made through linear regression analysis program. The results show that the drying procedure of chitin under infrared ray can accurately be described by the Page model, and the drying rates and moisture contents at different drying stages can also be easily estimated by it.
