3.5 SANITIZING THE FREEZER AND FREEZER
PARTS
After the freezer parts have been soaked and washed in
warm, soapy water, they should be rinsed thoroughly in
clean water.
All parts must be sanitized before assembling with a
USDA certified food grade sanitizing solution (50 parts per
million of free available chlorine or equivalent is accept-
able).
A. Mix a sanitizing solution of 50 parts per million to
sanitize all loose parts before assembling.
B. Place all loose parts in this solution, then remove
and let air dry.
C. Using this sanitizing solution and the brushes pro-
vided, sanitize the product cylinder and product
outlet by dipping the brush in the sanitizing solution
and scrubbing these areas.
D. After assembling the freezer (Section 3.6), mix approx-
imately 3 gallons (11.3 liters) of sanitizing solution and
pour into the product cylinder. Brush the walls of the
cylinder above the divider plate, with brushes provided
to sanitize this reservoir area.
E. Set the STIRRING ONLY-OFF-STIRRING &
FREEZING switch in the STIRRING ONLY position
and allow to stir for five minutes. Drain the solution
in the same manner as draining the product.
F. Pour approximately one pint (1/2 liter) of mixed
neutral base into the product cylinder. Wait one minute,
then drain the neutral base and remaining sanitizing
solution through the drain spigot.
Sanitizing must be done after the freezer is clean and just
before the product cylinder is filled with mixed neutral
base. Sanitizing the night before is not effective. However,
you should always clean the freezer and parts after use.
WARNING
THE UNITED STATES DEPARTMENT OF
AGRICULTURE AND THE FOOD AND DRUG ADMINIS-
TRATION REQUIRE THAT ALL CLEANING AND SANI-
TIZING 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 disinfecting
products and procedures. The frequency of sanitizing
must comply with local health regulations.
CAUTION
PROLONGED CONTACT OF SANITIZING SOLUTION
WITH FREEZER MAY CAUSE CORROSION OF STAIN-
LESS STEEL PARTS.
3.6 ASSEMBLY OF FREEZER
To assemble the freezer and freezer parts, refer to the
following steps:
NOTE
Petro-Gel sanitary lubricant or equivalent must be
used when lubrication of parts is specified.
The United States Department of Agriculture and the
Food and Drug Administration require that lubricants
used on food processing equipment be certified for
this use. Use lubricants only in accordance with
manufacturers instructions.
A. Assemble the divider plate and agitator
assembly as follows:
1. Before installing the drive shaft, lubricate the
bottom with Petro-Gel or any other type of sanitary
lubricant. Enough lubricant must be applied to
create approximately a 1/8 inch bulge at the bottom
of the drive shaft (Fig.24).
