Industrial Freezing Food Vacuum Dryer Used for Apple Banana Drying

Description

Pure water has a maximum speed at which vaporization Boiling state. Under normal conditions, about 100 ℃ when the water began to Boiling.

And in vacuum conditions, due to the system of water vapor partial pressure of water vapor partial pressure far below the surface of the material,

the boiling point of water is less than 100 ℃. For example: the surface down to -0.07MPa, water starts at 70 ℃ Boiling.

So, although at a lower operating temperature of the dryer is still a large drying capacity.
