Troubleshooting
CAUSE OF CONTAMINATION
PREVENTION
4. Improper cleaning and sanitation procedures.
(Continued)
d. Use a few good employees to follow the
cleaning procedure correctly and consistently.
Allow the employee uninterrupted time to
complete the cleaning procedure.
e. Hold sanitizing solution in the hopper and the
freezing cylinder for five minutes.
f. Wash and sanitize the tube of lubricant. After
each use, always recap the tube.
g. Parts, components, and brushes should be
air‐dried overnight. Never store the equipment in
the storage cooler.
h. Do not neglect daily cleaning practices: Wipe
the external areas of the freezer periodically
throughout the day, remove the design caps and
sanitize the area, and check the drip trays and
splash shield.
5. Mix stored improperly. a. Rotate stock to use older date code mix first.
The shelf life of mix is normally 10 days.
b. Mix must never be stacked outside or under
direct sunlight while waiting to be placed in the
cooler.
c. Place the mix directly in the cooler. Always
leave one inch between the mix and other
products to allow air to circulate around the
product.
d. Mix must not remain at room temperature for
long periods of time.
e. Hopper storage must maintain a temperature of
39_F (3.9_C). Storage temperatures above
45_F (7.2_C) will allow cell division in as little as
one hour.
f. Once the mix is placed in the hopper, covers
must be properly installed to maintain adequate
refrigeration and to prevent airborne
contaminants from entering the mix.
