| Abstract: | The heat and mass transfer characteristic of carrot in the freeze-drying process is studied by the freeze-drying experime- nts of the middle and external part of carrot.The freeze-drying model of carrot in the course of sublimation is found.The compari- sons of model paremeters and the freeze-drying time are made bet- ween the calculated results by model and experiment results. |
