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 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 nugget, which is more heavily compressed

and contains less water than freshly made flaked

ice.
