<p>A slurry of ice crystals and brine or aqueous beverage solution is forced through a conduit against a counterflow of butane or Freon as a wash fluid. The wash fluid emerges from the conduit through perforated or porous wall portions to enter a brine tank in which brine separates from the wash fluid and is removed. Washed crystals emerge from the conduit in a melt tank containing wash fluid. The crystals are melted, separated from the wash fluid, and withdrawn as fresh water. The wash fluid is pumped from the brine tank to the melt tank to cause its counterflow through the ice crystals. Alternately, the wash fluid may be introduced along the length of the conduit to flow to both tanks and be recirculated.</p> |
