3.3 SANITIZING
Sanitizing must be done after the freezer is cleaned and
justbeforethehopperisfilledwithmix.Sanitizingthenight
beforeisnoteffective.However,youshouldalwaysclean
the freezer and parts after using it.
WARNING
THE UNITED STATES DEPARTMENT OF AGRI-
CULTUREAND THE FOODANDDRUGADMINIS-
TRATION REQUIRE THAT ALLCLEANING AND
SANITIZING SOLUTIONS USED WITH FOOD
PROCESSING EQUIPMENT BE CERTIFIED FOR
THIS USE.
Whensanitizingthefreezer,refertolocalsanitaryregula-
tions for applicable codes and recommended sanitizing
products and procedures. The frequency of sanitizing
must comply with local health regulations. Mix sanitizer
accordingtomanufacturer'sinstructionstoprovidea100
parts per million strength solution. Mix sanitizer in quan-
tities of no less than 2 gallons (7.5 liters) of 120°F water.
Allow sanitizer to contact the surfaces to be sanitized for
5minutes.Anysanitizermustbeusedonlyinaccordance
withthemanufacturer'sinstructions.
NOTE
Stoelting, Inc. has found that STERA-SHEEN
GREENLABEL SANITIZERANDCLEANER does
aneffectivejobofproperly sanitizing and cleaning a
soft serve freezer. We therefore include a sample
with each new freezer. Other products may be as
effective.Forfurtherinformationrefertocleaning and
sanitizinginformation Section3.13.

CAUTION
PROLONGED CONTACT OF SANITIZER WITH
FREEZER MAY CAUSE CORROSION OF STAIN-
LESS STEEL PARTS.
In general, sanitizing may be conducted as follows:
A. Push the mix inlet regulator into hopper with air
inlet(long)tube towardthefrontofthefreezer
(Fig.11).
E. Afterfiveminutes,placeabucketunderthespigotand

(Fig.12.)
3.4 FREEZEDOWNANDOPERATION
This section covers the recommended operating proce-
durestobefollowed for thesafeoperationofthefreezer.
A. Sanitize just prior to use.
B. Place the OFF-ON switch in the OFF position.
C. With spigot open, pour approximately 1 gallon (3.8
liters)ofmixintothehopper.Allowthemixtoflushout

H. Fornormaldispensing,movethespigothandlefully

Mix does not improve with age. Old mix, or mix that has
been stored at too high temperature, can result in a
finished product that is less than satisfactory from the
appearanceandtastestandpoint.Toretardbacteriagrowth
indairybasedmixes,thebeststoragetemperaturerange
is between 36° to 40°F (2.2° to 4.4°C).
Some products tend to foam more than others. If excess
foam should occur, skim off with a sanitized utensil and
discard. Periodically, stir the mix in the hopper with a
sanitized utensil.
3.6 REMOVINGMIXFROMFREEZER
Toremovethemixfromthefreezer, refer to the following
steps:
A. Removethemixinletregulatorfrom thehopperby
pulling straight up (Fig. 16).
B. Place the OFF-ON rocker switch in the ON position
andpushtheCLEANswitchtorotatetheauger.Allow
the mix to agitate in freezer barrel until the mix has
become a liquid, about 5 minutes.
C. Draintheliquidmixbyopeningthespigot.Abucketor

3.5 MIXINFORMATION
Mix can vary considerably from one manufacturer to
another.Differencesintheamountofbutter-fatcontentand
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's mix to another. Soft serve mixes should
provide a satisfactory product in the 18° to 20°F (-7° to
-6°C)range, shakemixes24° to28°F(-4° to-2°C).
When checking the temperature, stir the thermometer in
thefrozenproducttoread the true temperature.
