土豆片的微波干燥特性及较佳工艺研究

The Drying Characteristics and Technology of Potato Slices by Microwave

进行了微波干燥土豆片的正交试验,得出微波干制土豆片失水特性及耗电特性;进行了回归分析,获得了微波干燥土豆方程,采用Page方程拟合较佳。进行了3因素4指标的二次正交回归试验,得出各指标的回归方程、3因素对4指标影响的显著性,并进行参数综合优化,提出了参数的较佳组合。

A series of microwave drying rests on potato have been conducted,the dehydrating characteristics and power consumption characteristics were obtained. It was indicated that the regression model of microwave drying on potato slices accord with the equation of Page.And the objective functions and the better drying programs under various indexes are obtained. Through the combination optimization analysis on the three factors respectively,we find when the former-power and latter-power both reach 3.2W/g,the objective functions are optimized.In this paper,the influences of the three factors on the indexes are briefly analyzed.
