During Cleaning and Sanitizing
Cleaning and sanitizing schedules are governed
by federal, state, or local regulatory agencies,
and must be followed accordingly. If the unit
has a “Standby mode”, it must not be used in
lieu of the proper cleaning and sanitizing
procedures and frequencies set forth by the
ruling health authority. The following check
points should be stressed during the cleaning
and sanitizing operations.
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.
ALWAYS FOLLOW LOCAL HEALTH CODES.
Troubleshooting Bacterial Count
j
1. Thoroughly clean and sanitize the unit daily,
including complete disassembly and brush
cleaning.
j
2. Use all brushes supplied for thorough
cleaning. The brushes are specially designed
to reach all mix passageways.
j
3. Use the white bristle brush to clean the mix
inlet hole which extends from the mix hopper
down to the rear of the freezing cylinder.
j
4. Use the black bristle brush to thoroughly
clean the rear shell bearing located at the rear
of the freezing cylinder. Be sure to have a
generous amount of cleaning solution on the
brush.
j
5.
If local health codes permit the use of
rerun,
make sure the mix rerun is stored in a
sanitized, covered stainless steel container
and used the following day.
IMPORTANT:
The unit must be primed with FRESH mix.
Afterward, during the day's operation, rerun
can be combined with fresh mix in a ratio of
50/50. Before using rerun, skim off the foam
and discard.
j
6. The bacteria cycle must be broken every
seven (7) days. On a designated day of the
week, run the mix as low as feasible and
discard it after closing. This will break the
rerun cycle and reduce the possibility of high
bacteria and coliform counts.
j
7. Properly prepare the approved cleaning and
sanitizing solutions. Read and follow label
directions carefully. Too strong of a solution
may damage the parts and too weak of a
solution will not do an adequate job of
cleaning or sanitizing.
j
8. The temperature of the mix in the mix hopper
and walk-in cooler should be below 40°F
(4.4°C).
Regular Maintenance Checks
j
1. Replace scraper blades that are nicked or
damaged. Before installing the beater
assembly, be certain that the scraper blades
are properly attached to the helix.
j
2. Check the rear shell bearing for signs of wear
(excessive mix leakage in drip pan) and be
certain it is properly cleaned.
j
3. Using a generous amount of cleaning solution
and the black bristle brush, brush clean the
rear shell bearings and hex drive couplings at
the back of the freezing cylinders to keep
them clean and free of lubricant and mix
deposits.
j
4. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
j
5. Follow all lubricating procedures as outlined in
the “Assembly” section.
