ABSTRACT:
The invention provides a filter for removing liquid from an ice slurry. The filter includes a horizontal filter plate. The ice slurry is passed over the top of the filter plate. The filter includes a first stage where the liquid is removed from the ice slurry, thereby consolidating the ice particles into an ice bed. The liquid is removed by drawing the liquid out of the ice slurry through a set of slots in the filter plate by using a low suction pump. A second stage of the filter draws the remaining liquid entrained in the ice bed through another set of slots using a vacuum pump, which has a higher suction than the low suction pump used in the first stage. A clean water rinse may be sprayed on the ice bed in the second stage to improve the removal of liquid from the ice bed. The filter plate at the second stage may be heated to produce a rinse through the bottom of the ice bed.
