Factors that affect the efficiency of the freeze dryer

1.drying room pressure

The pressure in the drying chamber affects the rate of heat transfer and mass transfer. In terms of mass transfer, the lower the pressure, the better. For heat transfer, the higher the pressure, the better. The mass transfer rate is mainly determined by the temperature and pressure of the sublimation interface and the surface of the dry layer. It is necessary to increase the rate of water vapor escape in the dry layer. First, increase the temperature of the sublimation interface and increase the vapor pressure of the interface. It is to increase the vacuum of the drying chamber and reduce the vapor pressure on the surface of the drying layer.

2.heat transfer mode heat transfer mode

According to the traditional classification, it can be divided into: conduction, convection, heat radiation and medium heating (microwave heating). Since the sublimation drying process involves the transfer of heat and mass (water vapor), the heat transfer method is more effective in transferring the heat to the material, which has a greater influence on the drying rate.
