Donut Robot Mark II / Mark V OM MN-1012EN 3
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.

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.

Make sure that both screw in the filter
assembly are tight. If they are not, the
filter assembly might slide off of the siphon
tube during operation, causing shortening
to splatter.
6. Place a five-gallon metal container under the
filter.
WARNING
Do not use a plastic container. Hot
shortening could melt the container.
Operation
1. Compress the bulb quickly and release it
quickly. Do this only once. Shortening
should flow into the container.
CAUTION
Do not compress the bulb more than once.
Doing so could allow hot shortening to get
into the bulb, damaging your equipment.
2. Watch the container as the shortening flows
into it. If the shortening rises to within 2”/
5 cm of the top of the container, do the
following:
a. With one hand, hold the siphon by the
handle. With the other hand, loosen the
thumb screw that holds the siphon
assembly to the mounting bracket on the
lip of the kettle.
b. Slowly lift the siphon assembly so its
opening is above the shortening. Do not
remove it from the mounting bracket.
c. Tighten the thumb screw.
d. When the shortening stops flowing and
the valve closes, move the container out
from under the filter.
e. Place another five-gallon metal container
under the filter.
f. With one hand, hold the siphon by the
handle. With the other hand, loosen the
thumb screw that holds the siphon
assembly to the mounting bracket on the
lip of the kettle.
g. Slowly lower the siphon assembly so its
opening is near the bottom of the kettle.
h. Tighten the thumb screw.
i. Restart the siphon, as explained in
step 1.
j. Continue watching the container and
repeat the above procedure as needed.
WARNING
If you allow shortening to overflow the
container, the shortening could burn you,
and it will get on the floor, possibly causing
slips, falls, injury, or even death. If
shortening does get on the floor, thoroughly
clean and dry the floor right away.
3. When the shortening stops flowing, tilt up
the side of the kettle opposite the siphon.
Place a wedge under the side of the kettle to
hold it up. The remaining shortening will
now flow toward the siphon.
4. Set aside the container of shortening.
5. Remove the filter assembly.
6. Place a different container under the valve
assembly and start the siphon again. Drain
the remaining shortening and discard it; it
will be full of sediment.
Cleaning
1. Remove the siphon from the Donut Robot.
2. Squeeze the bulb several times to expel
shortening from the siphon.
3. Wipe the siphon clean and hang it with the
bulb side up so any remaining shortening
will drain. Place a pan under the siphon to
collect the shortening.
4. Rinse the filter bag and hang it to dry. You
may launder it as needed.
WARNING
After washing, be sure the Filter Flo
Siphon is completely dry before using it
again. Moisture will cause hot shortening
to spatter, which may cause serious injury.

5 Donut-Making Helps
Tips on Making Quality
Cake Donuts
•Use the correct batter temperature.
In general, the correct batter temperature is
75°-80°F/24°-27°C. Check the mix
manufacturer’s instructions, as the
recommended temperature range may vary.
If the batter is too warm, the donuts will lack
volume and may “ring out” or be misshapen.
If the batter is too cold, the donuts will stay
under the shortening too long, fry too
slowly, and crack open or ball up. They
may also absorb excess shortening and lose
volume.
•Use the correct floor time.
A floor time of 10 minutes between mixing
and cutting allows the baking powder to
react with the water. This helps the donuts
attain the proper volume and absorb the
proper amount of shortening.
If the floor time exceeds 30 minutes, the mix
will gas off, the donuts will lose volume and
shape and will absorb too much shortening.
•Use the correct frying temperature.
The correct shortening temperature for
frying is 370°-380°F/188°-193°C.
If the shortening is too hot, the donuts will
fry too quickly on the outside and will lose
volume. The donuts may also become dense
inside.
If the shortening is too cold, the donuts will
spread too rapidly, will form large rings, will
tend to crack open, will be too light in
appearance, and will absorb too much
shortening.
•Maintain the proper shortening level. We
recommend a distance of 1 1/4” between the
depositor and the shortening.
If the shortening is too deep, the donuts may
not turn over when they reach the turner,
causing them to cook unevenly.
If the shortening is too shallow (too far
below the depositor), the donuts may not
drop flat, may turn over while submerging
and surfacing, and may become irregular,
cracked, or rough-crusted.
•Ensure that the donuts absorb the right
amount of shortening.
Donuts should absorb 1-1/2 to 3 oz/42 to 85
g of shortening per dozen, depending on
their weight. You can achieve proper
absorption by following tips 1-3.
•If the donuts do not absorb enough
shortening, they will not keep well.
If they absorb too much shortening, they will
lose volume and may become misshapen. If
this happens, follow tips 1-3, mix the batter
a little longer than usual, turn the donuts as
soon as they become golden brown, and turn
the donuts only once.

Calculating Correct Water
Temperature
The following is an example of how to calculate
the correct water temperature to use. You must
use your own room temperature, dry mix
temperature, desired batter temperature, and, if
you are making yeast-raised donuts, estimated
temperature increase during mixing.
Ratios of Plunger Sizes to
Donut Weights
The weights given are for donuts without icings
or other toppings. They are provided for
reference only, as weights vary according to the
