OPERATION
ICE STORAGE AND DISPENSING
Ice is stored in the dispenser’s bin. Ice below the stainless steel bin liner is used to cool the aluminum cold plate, at
the bottom of the ice dispenser bin. Ice above the stainless steel bin liner is dispensed into the customer’s cup.
Ice is transported from the bin to the ice dispense point by the paddle wheel and vertical auger. The injection
molded paddle wheel has paddles which push the ice into a vertical auger that carries it to the dispense point.
ICE AGITATION
The paddle wheel and auger carry ice. Periodic agitation is standard on the LP-3. During periodic agitation, the
paddle wheel, auger and agitator turn for approximately three seconds every hour. The door lock prevents ice from
being dispensed during the agitation cycle.
ROCKING CHUTE ICE DISPENSING
COLD PLATE BEVERAGE COOLING
A cold plate is a block of aluminum with serpentine stain-
less steel tubes molded inside the aluminum block. The
cold plate is approximately the same length and width
as the bottom of the dispenser bin. Ice sits on top of the
cold plate and cools the cold plate.
The stainless steel tubes inside the cold plate carry car-
bonated water (soda water), noncarbonated water (plain
water) and syrup to the beverage valves. While flowing
through the stainless steel tubes in the cold plate, water
and syrup are chilled to serving temperature.
BEVERAGE VALVES
Post-mix beverage valves are designed to precisely meter the flow of both water and syrup to obtain the proper
mixing ratio. The syrup and soda water components of the post-mix beverage are mixed as they leave the bever-
age valve.
As the customer presses the rocking chute, the arm at
the top left rear of the chute pushes upward on the door
lock. The door opens until it contacts the stops in the
mounting brackets. The plastic arm on the ice chute also
activates the lever of the ice dispensing switch. When
activated, the micro switch starts the gear motor and
auger motor. The gear motor turns the paddle wheel and
agitator bar, the auger motor turns the auger.
ICE AUGER
Ice is pushed into the auger by the paddlewheel. The auger lifts the ice from the bottom of the bin to the ice
dispense point at the rocking chute.
