1、Was the air flow rate of the TGA changed, to show, that the drying kinetics is independent from mass transfer by film diffusion?
TGA空气流速的改变说明了干燥动力是不受薄膜传质扩散影响?
2、A drying model for all temperature with one set of parameters describing drying for all experiments is scientifically far more interesting (applying multi variate regression). Fitting single sets of individual model parameters for every temperature is not "state of the art".
所有温度的干燥模型以及一系列的参数来描述干燥实验更好。 单独的独立模型参数是不够的。
3、Re heat of water evaporation:
If e.g. potato are dried, more energy is necessary for the evaporation of water as the literature value for the evaporation of pure water. Additional energy is required to desorb the water molecules from the potato's matrix. As lower the water content is, as bigger is the ration qreal/dvH! It could be concluded, that this effect also accounts for drying of cotton stalk.
审稿人举了个例子,说明水能量需求和水含量的影响。应该是个建议,希望你考虑。
4、10.9% water content in wet basis was measured - how does this compare to the heat to evaporate this amount of water?
