The mechanism of Vacuum cooler

The evaporation temperature decreases when the pressure of the air is lowered. This machine uses this properties to evaporate the water on the surface of foods and cool them.

After materials are set inside the machine, vacuuming pump will be started to decrease the pressure of the chamber and the materials are cooled consequently.
The evaporated moisture will be captured inside a cold trap and be discharged from liquid receiving container, in a liquid state.

Features of Vacuum cooler

  • By vacuum cooling fresh vegetables, its respiratory heat can be suppressed and the freshness of foods during transportation can be maintained.
  • Thanks to a reduced cooling time, it helps limiting the proliferation of germs.
  • It also reduces the load on your freezer during transportation or storage.
