3.3 SANITIZING
Sanitizing must be done after the freezer is cleaned and
justbeforethehopperisfilledwithmix.Sanitizingthenight
before is not effective. However, you should always clean
the freezer and parts after each use.
THE UNITED STATES DEPARTMENT OF AGRI-
CULTURE AND THE FOOD AND DRUG ADMIN-
ISTRATION REQUIRE THATALL CLEANINGAND
SANITIZING SOLUTIONS USED WITH FOOD
PROCESSING EQUIPMENT BE CERTIFIED FOR
THIS USE.
When sanitizing the freezer, refer to local sanitary regula-
tions for applicable codes and recommended sanitizing
products and procedures. The frequency of sanitizing
must comply with local health regulations.
Mix sanitizer according to manufacturer’s instructions to
provide a 100 parts per million strength solution. Mix
sanitizer in quantities of no less than 2 gallons (7.5 liters)
of 120°F water. Allow sanitizer to contact the surfaces to
besanitizedfor5minutes.Anysanitizermustbeusedonly
in accordance with the manufacturer’s instructions.

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 pushes the PUSH T O
FREEZE switch. 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.
3.5 MIX INFORMATION
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.
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).
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).
Some products tend to foam more than others. If foam
appearsinthehopper,skimoffwithasanitizedutensiland
discard. Periodically, stir the mix in the hopper with a
sanitized utensil to help prevent excess foam.

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.
3.13 PREVENTIVE MAINTENANCE
It is recommended that a maintenance schedule be fol-
lowed to keep the freezer clean and operating properly.
Cleaning and Sanitizing Information
Soft serve freezers require special consideration when it
comes to food safety and proper cleaning and sanitizing.
The following information has been compiled by Purdy

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
difficulttoremove and helpattributeto milkstone build-up.
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.
