Vacuum Freeze Dryer For Food

Like other drying methods, vacuum freeze dryer for food must meet two basic conditions to maintain the continuous sublimation drying, namely, the continuous supply of conversion and the continuous elimination of generated steam. In the initial stage, if the material temperature is relatively high, the latent heat required for sublimation can be taken from the sensible heat of the material itself. However, with the continuous sublimation, the material temperature will soon fall to the temperature in equilibrium with the steam partial pressure in the drying chamber. At this time, if there is no external heating, the sublimation drying will stop. In the case of external heating, if the steam generated by sublimation is not eliminated in time, the steam partial pressure will rise and the material temperature will rise. When the freezing point of the material is reached, the ice crystals in the material will melt and freeze-drying cannot be carried out.

The supply process is a heat transfer process, and the steam removal process is a mass transfer process. Therefore, the sublimation drying process is a process of heat and mass transfer at the same time. Any process in nature has a driving force. The driving force of heat transfer in sublimation drying is the temperature difference between the heat source and the sublimation interface, and the driving force of mass transfer is the steam partial pressure difference between the sublimation interface and the steam trap (or cold drop). The greater the temperature difference, the faster the heat transfer rate; The greater the steam partial pressure difference, the faster the mass transfer (i.e. steam removal) rate.
