摘要

In order to analyze the drying characteristics of loofah, obtaining the optimal drying conditions. In this paper, the effects of different slice thickness and different temperature on the vacuum pulsation drying characteristics of loofah were studiedby vacuum pulsation drying method. The drying kinetics of loofah was analyzed and the drying model was established. The results show that the smaller the slice thickness, the higher the temperature, the faster the drying rate. The drying process is deceleration drying, which is well fitted with the weibull model. The range of correlation coefficient R2 is 0.99516-0.99864, the effective diffusion coefficient is (1.88581-3.77767) *10-8, activation energy is 195kJ/mol. The results can provide theoretical support for the dry production of loofah.
