Scotsman Flaked Ice Machines - Manual (Page 3)

Introduction
Scotsman has been manufacturing flaked ice machines since the early 1950s and
nugget ice machines since the early 1980s. Although there have been significant
changes in drive systems, bearings, materials and refrigeration, the basic flaker remains
a vertical refrigerated cylinder containing water and a slowly rotating auger. As the
auger rotates it pushes soft, water laden crystalline ice to the outlet, where it is either
extruded or compressed into nugget or flaked ice.
This booklet contains the technical information to service all current and recent flaked or
nugget ice machines. Older, long obsolete models are not included.
