1 Introduction

The Donut Robot® Mark II and Mark V are designed to automatically deposit and fry cake donut products, and to fry yeast-raised donut products. It is not designed to deposit or fry any other products. The Donut Robot is designed to be used on a flat, stationary table or countertop, with the operator standing opposite the heater head of the machine. The operator must work safely at all times and read this manual and follow its instructions and warnings. The Donut Robot® produces only 71.5 dB(A) of equivalent A-weighted sound pressure at workstations. This has been determined during a dry run of the machine, using a Bruel & Kjaer sound level meter, type 2236. Study the instructions and warnings in this manual carefully. A thorough understanding of how to install, maintain, and safely operate the Donut Robot® will prevent production delays and injuries. To use the Donut Robot® safely, heed the following warnings and all other warnings that appear in this manual:
Make sure the machine is secured to the
work surface. Doing so will prevent the machine from moving or falling, which could cause serious injury.
Never let water and hot shortening come
in contact with each other. Moisture causes hot shortening to spatter, which may cause serious burns.
Do not overfill the kettle with
shortening. If shortening overflows the
kettle, it could cause serious burns or could cause someone to slip on the floor and be seriously injured.
Hot shortening can cause serious burns.
Make sure that the system and the shortening are cool before attempting any adjustment, repair, disassembly, or cleaning.
To avoid electrocution or other injury,
unplug the machine before attempting any adjustment, repair, disassembly, or cleaning.
To avoid damaging the machine, never
use force to assemble, disassemble, operate, clean, or maintain it.
Be careful never to get shortening, water,
or other materials on the floor. If anything does get spilled on the floor, clean the area immediately. Materials on the floor can cause people to slip or fall, resulting in serious injury or loss of life.
To prevent unintentional startup and
possible fire, unplug the machine if there is a local power outage. When the power is restored, it is safe to plug the machine in again.
To avoid electrocution, make sure that
all electrical cords are not frayed or cracked and that they do not pass through any water or shortening.
Make sure that all electrical cords are
routed so that no one will trip over them.

9. Connect the Cake Donut Depositor or
Feed Table to the electrical connector socket located at the left end of the control panel.

Inserting Shortening

WARNING
Hot shortening is much hotter than boiling
water! It will cause severe burns if it
touches your skin. Never touch hot
shortening. Always exercise extreme
caution with hot shortening. Use oven
gloves when working near hot shortening.
1. When the shortening reaches the correct
frying temperature, it should reach the top of the flight bars or chains.
2. If your fryer has a drain, close the drain
valve.
3. Put shortening in the kettle using one of
these methods: a. Pre-melt shortening in a pan on the stove
and carefully pour it into the kettle.
b. Use the optional EZ Melt to melt
shortening and transfer it to the kettle. See your EZ Melt manual.
c. Put solid shortening into the kettle,
packing it tightly around the elements and bulbs without air spaces.
WARNING
Air spaces can cause the shortening to
overheat and catch on fire. Pack the
shortening tightly without air spaces.
WARNING
Shortening expands as it increases in
temperature. Do not fill shortening all the
way up to the flight bars or chains, if it is
cold. The shortening level will rise by up to
1 inch (25 mm) when it is fully heated.

Heating Shortening

1. Turn on the FRYER HEAT switch (the
temperature controller will turn on). a. If you are heating solid shortening using
method 2c above, turn the heat switch on and off every 10 seconds, until the solid shortening has melted and no air pockets remain.
IMPORTANT
If you are heating solid shortening, turn
the heat switch on and off every 10 seconds,
until shortening has melted around the
elements and no air pockets remain.
2. Wait for the shortening to reach the desired
temperature. When it does, the Temperature Control light on the front of the heater head will turn off and the conveyor will start. DO NOT run the conveyor until all the shortening has melted.
3. If you are using the optional Shortening
Reserve Tank, fill it with shortening. Then position it on the conveyor side panels either ahead of or behind the turner, but not above it. The heat of the fryer will melt the shortening in the tank.

a. Hold a mixing bowl or other
receptacle under the depositor hopper.
b. Hold DOWN the switch on the
depositor until it has dropped two or three donuts into the bowl.
NOTE
Holding down the prime switch causes the
depositor to run continuously without the
normal delay between cuts.
c. Put the batter in the bowl back into
the hopper.
5. Return the hopper into position over the
fryer and reconnect the swing connecting rod to the swing column throw arm.
6. Turn the FRY TIME dial to adjust the
fry time to the desired speed.

the Feed table/Cake Donut depositor switch to CAKE DONUT DEPOSITOR. For 1 donut (or 2 mini donuts) per row, set the switch to FEED TABLE.
8. Turn on the cake donut depositor by pushing
UP the switch on the depositor.
9. Set FRYER CONVEYOR switch to
AUTO.
NOTE
If the conveyor becomes jammed, a
warning buzzer will sound about a minute
later and stop when the conveyor is turned
off. The conveyor drive motor is impedance-
protected so it will not burn out due to
jamming.
WARNING
If the conveyor becomes jammed:
1. Turn off the conveyor drive and the heater.
2. Allow the system to cool down. HOT SHORTENING IS DANGEROUS.
3. Determine the cause of the jamming.
4. Clear it.
