200W Pharmaceutical Vacuum Freeze Dryer Machine For Solid Liquid Gaseous

FD Series Vacuum Freeze Dryer High Efficiency For Solid Liquid Gaseous

Description:

Water has three phases: solid, liquid and gaseous. According to the theory of phase equilibrium in thermodynamics, with the decrease of pressure, the freezing point of water does not change much, but the boiling point is getting lower and lower, and approaches the freezing
point. When the pressure drops to a certain vacuum, the boiling point of water coincides with the freezing point, and the ice can be directy vaporized into gas without being liquid. This process is called sublimation. Vacuum freeze-drying is to sublimate and remove frozen water from food under the three-phase point of water, i.e. at low temperature and low pressure. According to this principle, the wet matenal in the material can be frozen below the freezing point, so that the moisture in the material can be changed into solid ice, the the ice can be directly converted into steam under the appropriate vacuum environment, and then the water vapor condenser in the vacuum system can be used to condense the water vapor, so that the material can be dried. This method of obtaining drying by vacuum freezing is a process of changing and moving the state of water. This process occurs at low temperature and low pressure. Therefore, the basic princip e of freeze drying is the mechanism of heat and mass transfer at low temperature and low pressure We dry the material in freezing condition. During the drying process, the ice does not melt. The process of direct vaporization and dryingof ice from solid state is called freeze-drying (for short, freeze -drying).
