Vacuum freeze dryer device
Vacuum freeze dryer machine is that the freeze dryer device with vacuum to decrease the working pressure in freeze dryer equipment chamber. Freeze drying demands to be in vacuum condition, as the freeze drying is sublimation drying. That is why the freeze dryer device is likewise called vacuum freeze dryer machinery.
Water vapor vaporizing at a temperature level and also pressure. For instance, the water vapor will certainly be vaporized at 100 ℃ at a standard ambience (103250 ). This temperature level is likewise called boiling factor. As the reducing of pressure, the boiling factor of water will be lowering as necessary. When the stress decreased to 600Pa, the boiling factor of water will be <0 ℃. Water much less than 0 ℃, the condition of water is solid, called ice. Exactly how does ice evaporating/boiling? This is sublimation.
Vacuum freeze dryer equipment is that the freeze dryer machine with vacuum to decrease the working stress in freeze dryer machine chamber. Freeze drying demands to be in vacuum condition, as the freeze drying is sublimation drying. In natural status, it in some cases occurred sublimation, yet not always as well as continuous, that is why the vacuum freeze dryer machine is created a surrounding that allow ice sublimate constantly in a tank.
KEMOLO developed durable freeze-drying chamber and also air vent the air in the chamber to decrease the stress in the chamber, to develop a condition for ice to sublimate. The air in the chamber needs to be removed by vacuum pump. That is why the freeze dryer machine is also called vacuum freeze dryer machine. To get vacuum freeze dryer equipment with inexpensive price from providers as well as manufacturers, simply buy it from factory directly.
