Vacuum Ice Maker (VIM)

Vacuum Ice Maker - The Technology:

Inside the VIM freezer, water is exposed to a deep vacuum. The vacuum forces a small part of the water to evaporate while the remaining water freezes forming water-ice mixture.

The mixture (ice slurry) is pumped out from the freezer to an ice concentrator that separates the water from the ice crystals.

In order to maintain the deep vacuum in the freezer, the water vapor is continuously evacuated from the freezer, compressed and fed into condenser by IDE's unique centrifugal compressor. Condensing of the vapor requires cooling water at 5°C (41°F), which is supplied from a standard water chiller.
