微波场中蔗糖晶体生长动力学的研究

Study of Sucrose Crystal Growth Kinetics During Microwave Irradiating

采用微波热效应方法对蔗糖溶液进行真空蒸发结晶。实验证实，在微波环境中生长的蔗糖晶体之轴向生长速率比常规加热方法的蔗糖晶体的生长速率大；利用计算机处理相应数据，获得生长动力学模型，并对有关的机理进行了初步探讨。

Microwave thermal effect was applied in vacuum evaporative sucrose crystallization. It was proved in the experiments that the growth rates in the axis direction for sucrose crystal during microwave irradiating are greater than those by conventional heating. Their mathematic models of crystal growth kinetics with these two heating methods were established by computer,and the relative mechanism was also discussed.
