Preface

The Donut Robot Mark VID is designed to
automatically cut and fry cake donut products,
and to fry yeast-raised donut products. It is not
designed to cut or fry any other products.

The Mark VID is meant to be used on a flat,
stationary table or countertop. The operator must
work safely at all times and read this manual and
follow its instructions and warnings.

Study the instructions and warnings in this
manual carefully. A thorough understanding of
how to install, maintain, and safely operate the
Donut Robot Mark VID will prevent production
delays and injuries.

To use the Mark VID 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 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, mop it up
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.

 Always turn the thermostat knob below

100F/38C before filtering shortening,
draining the fryer, or cleaning the fryer.
Draining shortening with the heating
elements on may cause fire, serious injury, or
even death.

 Before attempting to remove the conveyor

assembly from the fryer, always allow the
shortening to cool, and drain the shortening
out of the fryer. If you do not, shortening
may splash on you and on the floor, creating
a safety hazard. If the shortening is hot, you
may suffer serious burns.

 To avoid electrocution or other injury,

unplug the machine before attempting any
adjustment, repair, disassembly, or cleaning.

Donut Robot Mark VID OM MN-1042EN 1

For general information on donut production,
refer to Section 7, “Donut-Making Helps.”

Read each step completely before doing what it
tells you to do.

Making Yeast-Raised
Donuts

1. Remove the hopper and plunger, the cutter
head, and the swing column, if they are
installed.

2. Pivot the splash guard down. (See Figure
1-1.)

3. When the shortening reaches the correct
frying temperature, it should reach the top of
the flight bars.

Shortening expands as it increases in
temperature. This means that unless the
shortening is at frying temperature when you
put it in the kettle, you should put it in
gradually. Let the shortening in the kettle
heat up before you add more.

4. Turn the heating elements on by turning the
thermostat knob to the desired temperature.
Two pilot lights will come on. The one on
the top of the heater head indicates that the
heating elements have been turned on (that
the thermostat is set above 200F/93C).
The one on the front of the heater head
indicates that the shortening has not yet
reached the desired temperature. This light
will go out if the high temperature limit
control breaks the circuit.

Note: If the high temperature limit control
does break the circuit, push the red reset
button on the back of the heater head.

5. Wait for the shortening to reach the desired
temperature. When it does, the light on the
front of the heater head will go out. DO
NOT run the conveyor until all the
shortening has melted.

6. Install your Feed Table and load proof cloths
on it. Refer to Appendix A, “Related
Products,” for complete installation and
operation instructions for the Feed Table.

Put shortening in the kettle using one of
these methods:

 Use the optional EZ Melt to melt

shortening and transfer it to the kettle.
See your EZ Melt manual.

 Pre-melt shortening in a pan on the stove

and carefully pour it into the kettle.

WARNING

Hot shortening causes severe burns.

 Put solid shortening into the kettle,

packing it tightly around the elements
and bulbs.

WARNING

Air spaces can cause the shortening to

overheat and catch on fire.

7. Choose the appropriate fry time for your
product using the fry time control knob on
the heater head.

8. Using the switch on the heater head, select
one cut per pocket. Although the machine
will not be cutting donuts, it needs to be at
this setting when frying yeast-raised
products.

9. Turn on the conveyor drive using the power
switch on the heater head.

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 is impedance­protected 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. 5. Restart the system.

10. Continue adding shortening to the kettle to
maintain the proper shortening level (see
step 3). There are two ways to do this:

 Transfer shortening from the optional EZ

Melt. See your EZ Melt manual.

 Melt some shortening in a pan on the

stove and carefully pour it into the kettle.

11. Continue loading proof cloths onto the Feed
Table as needed.

Making Cake Donuts

1. Pivot the splash guard toward the outfeed
end of the fryer. (See Figure 1-1.)

2. Install the swing column, connect the swing
connecting rod, install the cutter head, and
install the hopper and plunger, if you have
not done so already.

3. When the shortening reaches the correct
frying temperature, it should reach the top of
the flight bars.

Shortening expands as it increases in
temperature. This means that unless the
shortening is at frying temperature when you
put it in the kettle, you should put it in
gradually. Let the shortening in the kettle
heat up before you add more.

4. Turn the heating elements on by turning the
thermostat knob to the desired temperature.
Two pilot lights will come on. The one on
top of the heater head indicates that the
heating elements have been turned on (that
the thermostat is set above 200F/93C).
The one on the front of the heater head
indicates that the shortening has not yet
reached the desired temperature. This light
will go out if the high temperature limit
control breaks the circuit.

Note: If the high temperature limit control
does break the circuit, push the red reset
button on the back of the heater head.

5. Wait for the shortening to reach the desired
temperature. When it does, the pilot on the
front of the heater head will go out. DO
NOT run the conveyor until all the
shortening has melted.

6. Disengage the swing connecting rod from
the swing column throw arm and swing the
hopper away from over the fryer.

7. Adjust the size selector dial on the cutter
head’s crankshaft assembly. This dial
regulates the donut weight. The higher the
setting, the larger the donuts will be. Adjust
the dial setting as follows:

a. Unscrew the dial lock nut 1/2 turn.

b. Turn the dial to the desired position, as

indicated by the marks on the crank
plate.

c. Tighten the dial in place with the lock

nut. Tighten it using your fingers only.

8. Put dough into the hopper. Prime the hopper
to expel any air that may be trapped in the
bottom of it. To prime the hopper:

a. Hold a mixing bowl under the cutter.

b. Hold down the prime switch on the

cutter head and run the cutter until it has
dropped two or three donuts into the
bowl.

Note: Holding down the prime switch

causes the cutter to run continuously
without the normal delay between cuts.

c. Put the dough in the bowl back in the

hopper.

9. Return the hopper into position over the
fryer and reconnect the swing connecting
rod to the swing column throw arm.

10. Choose the appropriate fry time for your
product using the fry time control knob on
the heater head.

11. Using the switch on the heater head, select
the number of donutsone or twoyou want
to cut during each swing cycle of the hopper.

12. Turn on the cutter using the power switch on
the cutter head.

13. Turn on the conveyor drive using the power
switch on the heater head.

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 is impedance­protected so it will not burn out due to
jamming.

for the Feed Table is working. To do this:

a. Turn on the Donut Robot’s conveyor

drive.

b. Turn on the Feed Table’s conveyor

drive.

The Feed Table should receive a signal

from the Donut Robot, move forward the
distance needed to supply one pocket of
donuts, and then stop until it receives the
next signal.

2. Proof your donuts on the proofing cloths
from the Feed Table.

3. Put a proofing board, with a proofing cloth
on it, on the Feed Table.

4. Press the prime switch on the power head
assembly. The hooks on the Feed Table will
grab the proofing cloth off of the proofing
board. Allow the cloth to advance to the
front of the Feed Table.

5. Release the prime switch and turn on the
main power. Remove the proofing board.

When the Feed Table is on, the Feed Table

automatically advances donuts when the
Donut Robot is ready to accept them. After
the donuts go into the fryer, the proofing
cloths are carried underneath the Feed Table
and fall onto the work surface.

6. Continue putting proofing cloths on the Feed
Table.

CAUTION

To avoid damaging the Feed Table, never

use force to assemble or operate it.

Daily Cleaning

If your feed table has a drip tray above the gear
box drive assembly, you must clean it daily. To
do so, follow these steps:

1. Remove the drip tray.

2. Wipe the drip tray with a soft, damp cloth.

3. Put the drip tray back in place.

If your feed table does not have a drip tray, you
must wipe the top of the gear box drive assembly
after each use. Use a soft, damp cloth.

To improve sanitation and to help your machine
continue to work well, clean the feed table daily.
Use a soft damp cloth to remove flour and other
debris. If necessary, you may use a small amount
of household dish detergent. Never use harsh or
abrasive cleaners.

WARNING

To avoid electrocuting yourself or

damaging the machine, never allow any

liquid to enter the power head.

splatter.

6. Place a five-gallon metal container under the
filter.

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.

WARNING

Do not use a plastic container. Hot

shortening could melt the container,

possibly burning you and getting

shortening on the floor. Shortening on the

floor could cause you to slip or fall,

resulting in injury or even death.

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

Donut Robot Mark VID OM MN-1042EN 19

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.

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
cutter 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 cutter), 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.

 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.

Belshaw Bros., Inc.  www.belshaw.com  Phone [phone]  Fax [phone]

Donut Robot Mark VID OM MN-1042EN 21

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

Temperature Conversion

To convert temperatures from Fahrenheit to
Celsius, subtract 32 from F and divide the result
by 1.8. For example, 212F-32/1.8 = 100C.

To convert temperatures from Celsius to
Fahrenheit, multiply C by 1.8 and add 32 to the
result. For example, (100C x 1.8) + 32 = 212F.

2 Maintenance

WARNING

To avoid being burned, electrocuted, or

otherwise injured, always unplug the

machine and allow it to cool before

performing any maintenance.

Lubricating

Daily

Before using the machine each day, apply edible­grade mineral oil to the plunger connecting rod.
The oil should penetrate the ball lock and the
spring socket. See Figure 2-1.

Weekly

 Apply a few drops of SAE 30 machine

oil to the swing column where it contacts
the swing column bracket.

 Remove the heater head cover and

lightly coat the gear teeth with
multipurpose grease. Replace the cover.
See Figure 2-2.

Yearly

Lubricate the conveyor drive motor as explained
below.

1. Disconnect the machine from the power
source.

2. Remove the back cover of the heater head.

3. Unscrew the two bolts that connect the
conveyor drive assembly to the bottom of
the heater head.

CAUTION

Be gentle with all parts of the conveyor
drive assembly, especially when pulling it
out of the heater head and putting it back

in the heater head.. Damaging the parts

could stop production.

4. Carefully pull the motor out of the heater
head. See Figure 2-3.

5. Apply 4 to 6 drops of SAE 30 machine oil
through the lubricating hole in the bearing
cap until the felt pad is saturated. See

Figure 2-4. Lubricating the Conveyor Drive

Motor.

6. Carefully put the motor back in the heater
head, bolt the motor to the heater head, and
replace the back cover of the heater head.

Checking the Thermostat

If the quality of your product decreases, check
the accuracy of the thermostat. Heat some
shortening in the fryer, measure the temperature
of the shortening using a thermometer you know
to be accurate, and compare this reading to the
thermostat setting. It is important that you put
the thermometer in the top 1”/2.5 cm or so of
shortening, because this is where the donuts are
fried, and this is where the temperature should be
consistent. If you need to calibrate the
thermostat, consult Section 8, “Electrical
Components.”

If you ever want to test the continuity of the
thermostat or any of the switches on your Donut
Robot, refer to Appendix C, “Electrical
Components.”

Taking Care of the Plunger,
Hopper, and Cylinder

The plunger, hopper, and cylinder of your Donut
Robot are precision instruments. If you take
good care of them, they will perform well for
years. Follow these guidelines:

 Clean these parts only in the manner

explained in this manual.

 Handle these parts with care. Avoid

dropping them on hard surfaces.

 Do not force the machine if it becomes

jammed. To avoid damaging the
plunger, disassemble the machine and
remove any obstructions.

Feed Table Maintenance

If you ever need to adjust the tension of the
conveyor chains, follow these steps:

1. Loosen the hex head bolts that hold the
roller shaft at the outfeed end of the
conveyor.

2. Pull the shaft until the chains reach the
correct tension. The tension is correct when
you can lift the chains about 1” (2.5 cm)
above the surface of the Feed Table. Each
chain should have the same tension.

3. Tighten the hex head bolts that hold the
roller shaft.

WARNING

4 Electrical Components

This section explains how to check and adjust the
thermostat on a Donut Robot® fryer. Do this if
the temperature on the Temperature Control dial
does not match the temperature reading taken by
a reliable thermometer or temperature probe.

Adjusting the Thermostat
(“Temperature Control”)

1. This procedure requires about 15 minutes

if the fryer is hot. Do not perform this test
while making donuts.

2. Have a reliable thermometer or

temperature probe ready that reads up to
400°F ( or 200°C).

3. If the shortening is liquid, turn on the

fryer conveyor. This will circulate the
heat evenly around the fryer.

4. Set the Temperature Control dial to

375°F (190°C). Allow the fryer to reach
operating temperature. When the fryer
reaches this point, the red light above the
Temperature Control should go OFF.

7. CAREFULLY insert the tip of your

thermometer or temperature probe
approximately 1” (25mm) below the
surface, close to the middle of the fryer.
DO NOT touch the shortening with your
hand or fingers, even with gloves on.

8. Wait for the light above the Temperature

Control to change from OFF to ON. Now
check the temperature on your
thermometer or probe. If the Thermostat
is working properly, this temperature will
show 370° to 375°F (188° to 190°C).

9. If not, an adjustment is needed as

follows.

10. Turn off the power to the Donut Robot®

by disconnecting the plug, OR by turning
the breaker switch at the back of the fryer
to the OFF position.

WARNING

To avoid the possibility of electric shock,

disconnect or turn off the power source

before adjusting the thermostat.

5. Turn off the fryer conveyor.

6. Use thick heat resistant gloves as a

precaution when performing the next
step. The shortening is HOT. NEVER put
your hand, fingers or other body parts
under the shortening.

11. Carefully lift up the Temperature Control

dial with your fingers or other implement,
until it comes off.

WARNING

NEVER touch shortening when it is hot,

even with gloves on. It can cause serious

burns. Avoid touching the surrounding

metal parts. They are HOT.

Belshaw Bros., Inc.  www.belshaw.com  Phone [phone]  Fax [phone]

24 MN-1043EN Donut Robot Mark VID TS

12. Loosen the screws that hold the

Thermostat in place under the dial. (See
photo above) You should NOT loosen the
screws all the way, or the Thermostat
might fall out.

13. If the temperature in step 6 was MORE

than 375°F (190°C), rotate the
Thermostat CLOCKWISE.

14. If the number you recorded in step 6 was

LESS than 370°F (190°C), rotate the
Thermostat COUNTER-CLOCKWISE.

15. Tighten both screws again and replace the

Temperature Control dial.

16. Connect power to the Donut Robot and

retest by repeating the process from Step
3 above.

17. If you are UNABLE to rotate the

Thermostat far enough to make the light
come on between 370° to 375°F (188° to
190°C), you should first check your
Thermometer. Get a 2

nd

thermometer and

compare the two.

18. If necessary, go back to Step 3 using the

most accurate thermometer.

19. If you are still UNABLE to rotate the

Thermostat far enough to make the light
come on between 370° to 375°F (188° to
190°C), have a qualified technician check
your fryer and if necessary replace the
thermostat. The part number is listed on
the wiring diagram attached to your
manual.
