3.7 CLEANING THE FREEZER
NOTE
The frequency of cleaning the freezer and freezer
parts must comply with local health regulations.
NOTE
The freezer has standby and sleep modes. When
the freezer is not used, after a preset number of
freezing cycles, it will enter the standby mode (fol-
lowed by sleep mode) and remain there until some-
one draws a product or presses the PUSH TO
FREEZE button. In the sleep mode, the freezer will
keep the product below 41°F (5°C). Sleep modes
are not to be used in place of cleaning and sanitiz-
ing. Frequency of cleaning and sanitizing is deter-
mined by Federal, State, and local regulatory agen-
cies.
After the mix has been removed from the freezer, the
freezer must be cleaned. To clean the freezer, refer to the
following steps:
A.
Fill the hopper with 2 gallons (7.5 liters) of tap
water.
B.
Place the Main Freezer Power OFF-ON switch in
theONpositionandpresstheCLEANswitch.The
auger will start to rotate.
C.
Allow the water to agitate for approximately 30
seconds.
NOTE
3.5 MIX INFORMATION
If freezer is left in CLEAN for more than 20 minutes,
the display will show an error code. To reset, place
the Main Freezer Power OFF-ON switch in the OFF
position and back in the ON position.
Mix can vary considerably from one manufacturer to
another. Differences in the amount of butterfat content
and quantity and quality of other ingredients have a direct
bearingonthefinishedfrozenproduct.Achangeinfreezer
performance that cannot be explained by a technical
problem may be related to the mix.
D.
E.
Open the spigot to drain the water. Remember to
place a container under the spigot to catch the
water. When the water has drained, place the
switch in the OFF position. Allow the freezing
cylinder to drain completely.
Proper product serving temperature varies from one
manufacturer’smixtoanother.Softservemixesgenerally
providesatisfactoryproductfrom18°to20°F(-7°to-6°C),
shake mixes 24° to 28°F (-4° to -2°C).
Prepare detergent water by mixing 2 oz. of
Palmolive detergent or equivalent in 2 gallons of
90° to 110°F (32° to 43°C) water. Repeat steps A
through D using the detergent solution.
When checking the temperature, stir the thermometer in
the frozen product to read the true temperature.
Old mix or mix that has been stored at elevated tempera-
tureswillproducepoor-qualityproductwithabadtasteand
unacceptable appearance. To retard bacteria growth in
dairy based mixes, the best storage temperature range is
between 36° to 40°F (2.2° to 4.4°C).
3.8 DISASSEMBLY OF FREEZER PARTS
CAUTION
Some products tend to foam more than others. If foam
appearsinthehopper,skimoffwithasanitizedutensiland

The following information has been compiled by Purdy
Products Company, makers of Stera-Sheen Green Label
Cleaner/Sanitizerandspecificallycoversissuesforclean-
ing and sanitizing frozen dessert machines. This informa-
tion is meant to supplement a comprehensive food safety
program.
Soil Materials Associated with Frozen Dessert
Machines
MILKFAT/BUTTERFAT – As components of ice-cream/
frozen custard mix, these soils will accumulate on the
interior surfaces of the machine and its parts. Fats are
difficult to remove and help attribute to milkstone buildup.
MILKSTONE – Is a white/gray film that forms on equip-
mentandutensilsthatcomeincontactwithdairyproducts.
Thesefilmswillaccumulateslowlyonsurfacesbecauseof
ineffective cleaning, use of hard water, or both. Milkstone
is usually a porous deposit, which will harbor microbial
contaminants and eventually defy sanitizing efforts.
Once milkstone has formed, it is very difficult to remove.
Without using the correct product and procedure, it is
nearly impossible to remove a thick layer of milkstone.
(NOTE: general-purpose cleaners DO NOT remove
milkstone.) This can lead to high bacteria counts and a
food safety dilemma.

In addition to food safety, milkstone can cause premature
wear to machine parts which can add to costs for replace-
ment parts or possibly more expensive repairs if worn
machine parts are not replaced once they have become
excessively worn.
CAUTION
Overtightening or uneven tensioning of circular
knobs may cause damage to front door and cause
leaking. Hand tighten circular knobs evenly.

CLEANING
•
•
Is the removal of soil materials from a surface.
Is a prerequisite for effective sanitizing.
NOTE
3.12 ROUTINE CLEANING
To remove spilled or dried mix from the freezer exterior,
simply wash in the direction of the finish with warm soapy
water and wipe dry. Do not use highly abrasive materials
as they will mar the finish.
An UNCLEAN surface will harbor bacteria that can
defy sanitizing efforts.
Bacteria can develop and resist sanitizing efforts within a
layer of soil material (milkstone). Thorough cleaning pro-
cedures that involve milkstone removal are critical for
operators of frozen dessert machines.
3.13 PREVENTIVE MAINTENANCE
It is recommended that a maintenance schedule be fol-
lowed to keep the freezer clean and operating properly.

products and procedures. Overall, the products and pro- components of the machine causing premature wear and
cedures fall into three separate categories. (Please note metal corrosion.
that this is a brief overview intended for informational
purposes only.)
GENERAL PURPOSE CLEANERS
General purpose cleaners do not have the ability to re-
move milkstone. Milkstone will become a problem if not
remedied with additional products and procedures.
1.
CLEANING – This involves draining mix from the
freezerbarrelandrinsingthemachinewithwater.
Next, acleanerisrunthroughthemachine. Then,
the machine is disassembled and removable
parts are taken to the sink for cleaning.
THE USE OF CHLORINE TEST STRIPS
“Test strips” are used to determine concentrations of
active chlorine in sanitizing solutions. To use the strips,
tear off a small portion and submerge it into the sanitizing
solution. Then, compare the color change to the color key
on the side of the test strip dispenser to determine the
approximate chlorine concentration.
2.
MILKSTONE REMOVAL – Since almost all
cleaners do not have the ability to remove
milkstone, the use of a delimer becomes
necessary. Although this procedure may not be
needed on a daily basis, it will usually follow the
cleaning procedure. It requires letting a delimer
solution soak in the machine for an extended
period of time. Individual parts are also soaked in
a deliming solution for an extended period of time
(more about delimers in Additional Information).
The ideal concentration of chlorine needs to be 100 ppm
(as stated by the FDA).
NOTE
Follow the directions on the container for proper con-
centration.
3.
SANITIZING–Afterthemachinehasbeencleaned
and contains no milkstone, the machine is
reassembled. Then a FDA-approved sanitizing
solutionisrunthroughthemachinetokillbacteria.
The machine is then ready for food preparation.
There are two main factors that contribute to falling chlo-
rine concentrations in a sanitizing solution.
1.
PRODUCT USE – As the chlorine in the solution
is being used, chlorine concentrations fall.

Additional Information
THE USE OF DELIMERS
A delimer is a strong acid that has the ability to dissolve
milkstone. This type of chemical may become necessary
once high levels of milkstone have developed. While
these products are very effective for removing HIGH
levels of milkstone, they are not ideal for two reasons:
CAUTION
Do not use acidic cleansers, strong caustic com-
pounds or abrasive materials to clean any part of
the freezer exterior or plastic parts. Use of these
types of cleaners will cause equipment damage.
1.
PRODUCTSAFETY–Strongacidsaredangerous

2.
MACHINE DAMAGE – Strong acids will attack
metal and rubber causing premature wear of
parts. The use of a delimer needs to be closely
monitored to avoid damage to machine surfaces
and parts.

QUARTERLY
WARNING
CAUTION
High voltage will shock, burn or cause death. Turn
off and lock out main power disconnect before ser-
vicing. Do not operate machine with panels re-
moved.
Do not over-lubricate; resulting damage could cause
motor failure.
3.14 EXTENDED STORAGE
The air-cooled condenser is a copper tube and aluminum
fin type. Condensing is totally dependent upon airflow. A
plugged condenser filter, condenser, or restrictions in the
louvered panel will restrict airflow. This will lower the
capacity of the system and damage the compressor.
Refer to the following steps for storage of the freezer over
any long period of shutdown time:
A.
B.
C.
Turn the Main Freezer Power OFF-ON switch to
the OFF position.
Disconnect (unplug) from the electrical supply
source.
The condenser must be kept clean of dirt and grease. The
freezer must have a minimum of 3” (7.5 cm) of ventilation
on the right and left sides of the unit for free flow of air.
Make sure the freezer is not pulling over 100° F (37° C) air
from other equipment in the area.
Clean thoroughly with a warm water detergent all
parts that come in contact with the mix. Rinse in
clean water and dry parts. Do not sanitize.
The water-cooled condenser is a tube and shell type. The
condenser needs a cool, clean supply of water to properly
