Based on the experiments on freeze-drying carrot and potato slabs,the effects of some parameters,suchas heating temperature and pressure on the freeze-drying process are examined.A simple model of freeze-drying isestablished to predict drying time and the mass variations of materials during the drying.The experimental resultsagree well with those calculated by the model.
