INTRODUCTION
CARBON DIOXIDE DRY ICE PELLETIZER
SPECIFICATIONS
METHOD OF OPERATION: The dry ice Pelletizer consists of a system for
injecting liquid CO
2
into a compression cylinder. The process of reducing the
pressure on the liquid from approximately 300 psi (20.68 bar), below the Triple
Point, to atmospheric pressure causes about 40% of the carbon dioxide to
change to a solid. The remaining carbon dioxide changes to a vapor and is
vented from the machine. Finally, the solid is hydraulically extruded through
a die to form dry-ice pellets. These pellets can range in size from 0.114” (2.9
mm) to 3/4” (19.05 mm) diameter. The LB-450 disk press has an extra step
that takes the extruded pellets and forms them into a disk 4” (101.6 mm) in
diameter by 1/2” (12.7 mm) thick.
HYDRAULIC SYSTEM:
• High oil temperature automatic shut-off (greater than 150 ºF (65.5 ºC))
• Low oil level automatic shut-off
• High pressure relief valve (see Table 1.2 on page 1.7 for actual setting of
each model
ELECTRICAL: Available to meet electrical requirements worldwide
(Capacities may vary due to frequency variation.)
FEATURES:
• U.S.D.A (United States Department of Agriculture) approved
• Automatic (unattended) operation
