How Ice Is Made
Refrigeration effect is applied to the water between
the auger and the evaporator. When that water's
temperature drops to its freezing point, ice crystals
form throughout it. A continually rotating auger moves
the ice up the evaporator tube. At this point the ice is
a soft ribbon that fills the space between the auger
and evaporator.
At the top of the evaporator tube, ice emerges from
the water and is forced or extruded through relatively
small openings. This has the effect of squeezing out
excess water and compressing the ice together into a
useable form.
Ice flowing up from the openings is forced to one side,
breaking it into smaller lengths. An ice sweep moves
them to the chute.
Flaked ice machines have 6 oblong and curved slots
that ice flows from, and they produce a softer, wetter
ice form.
Nugget ice machines have 16 round holes that form
the nuggets, which is more heavily compressed and
contains less water than freshly made flaked ice.
