동결층소멸을 이용한 동결건조 속도에 관한 연구

A Study on the Freeze Drying Rate with Frozen Layer

The drying rate in freeze drying was obtained by experiment of garlic moisture contents depending on the drying time. Freeze drying experiment of garlic juice was carried out in vaccum freeze drier of laboratory scale by backface heating, and a mathematical model is also used to simulate the process of simultaneous heat and mass transfer in freeze drying to compare with experimental data.
