Distribution of Vapor Pressure in the Vacuum Freeze‐Drying Equipment

In the big vacuum freeze‐drying equipment, the drying rate of materials is uneven at different positions. This phenomenon can be explained by the uneven distribution of vapor pressure in chamber during the freeze‐drying process. In this paper, a mathematical model is developed to describe the vapor...
