OPERATING PRINCIPLE

Product delivered to the feed hopper continues into a rotating
impeller. Centrifugal force holds the product against the inside of the
slice case as the impeller paddles carry the product past the slicing
knife. An adjustable case gate at the front of the case allows the
product to move forward across the edge of the slicing knife. The
opening between the end of the case gate and the slicing knife edge
determines the slice thickness. Slices then drop onto a revolving feed
drum. The drum and an opposing feed spindle transfer the slices to the
circular knife spindle where the product is cut into strips. The strips
then move directly into the rotating crosscut knives producing cubes or
rectangular pieces of predetermined size.

Model RA-A with optional stainless steel motor and caster
frame.

TYPES OF CUTS

DICES: A slicing knife, circular knife spindle, and crosscut knife

spindle are used for dicing. Changing the size of the cubes is done by
using the required cutting spindles and adjusting the slice thickness.

Slice thickness: 1/16 to 3/8" (1.6 to 9.5 mm)

Circular Knife Cuts: 1/8 to 1" (3.2 to 25.4 mm)

Crosscut Knife Cuts: .05 to 3" (1.3 to 76.2 mm)

STRIP CUTS: Removal of crosscut knife spindle and shaft will
enable the user of the RA-A to produce strips of different lengths as
determined by incoming product size. A circular spindle change may
also be required.
