some frozen diet dessert mixes. High ambient
temperaturesmay extendfreeze down time.
H. Fornormaldispensing, move the spigot handlefully
open(Fig. 15).
I. The freezer is designed to dispense the product at a
reasonabledrawrate. If thefreezeris overdrawn,the
result is a soft product or a product that will not
dispense at all. If this should occur, allow the freezer
torun for approximately 30 secondsbefore dispens-
ingadditional product.After awhile theoperator will
senseor feelwhen thefreezer is beginning to fall
behind, and will slow down on the rate of draw so as
not to exceed the capacity.
J. Do not operate the freezerwhen theMIX LOWlight
ison or with less than 1-3/4" (4.4 cm) of mix in the
hopper.Refill the hopperimmediately.
NOTE
Thefreezer hasa standbymode sometimes
referredto as asleep orenergy conservation
mode. When the freezer is not used, after a
preset time, it will enter the standby mode and
remainthere untilsomeone drawsa product or
pushesthe push-to-freezeswitch. Inthe
standbymode, the freezer will keep the product
below 45°F. Standby modes are not to be used
inplace of cleaning and sanitizing.Frequency of
cleaningand sanitizing isdetermined by Fed-
eral, State, and local regulatory agencies.
3.5 MIX INFORMATION
Mixcan vary considerably from onemanufacturer to
another.Differences intheamount ofbutterfat content
andquantity andquality of other ingredients havea
directbearing onthe finishedfrozen product. A change
infreezer performancethat cannotbe explained by a
technical problem may be related to the mix.
When changing from one type of mix to another such as
yogurt to Vitari, you may have to change the mix inlet
regulator and/or control settings. Please call your
distributorforfurtherinformation.
Properproductservingtemperaturevaries from one
manufacturer’smix to anther. Mixesshould providea
satisfactory product in the 18° to 20°F (-7° to -6°C)
range.
When checking the temperature, stir the thermometer in
thefrozen productto readthe true temperature.
Mix does not improve with age. Old mix, or mix that has
been stored at too high a temperature, can result in a
finished product that is less than satisfactory in taste
andappearance.Toretardbacteria growth indairy based
mixes,the beststorage temperature range 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 the foam off with a sanitized
utensil and discard. Periodically, stir the mix in the
hopper with a sanitized utensil.
