Operator Checklist
During Cleaning and Sanitizing
Note:
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 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.
IMPORTANT! Cleaning and sanitizing must be
performed daily.
Troubleshooting Bacterial Count
Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach all
mix passageways.
Use the brush to clean the mix inlet hole which
extends from the mix hopper down to the rear of
the freezing cylinder.
Use the black bristle brush to thoroughly clean the
rear shell bearing located at the rear of the
freezing cylinder. Be sure there is a generous
amount of cleaning solution on the brush.
If local health codes permit the use of rerun, make
sure the mix rerun is stored in a sanitized, covered
stainless steel rerun container and used the
following day.
Do not
prime the machine with
rerun. When using rerun, skim off the foam and
discard; then mix the rerun with
fresh
mix in a
ratio of 50/50 during the day's operation.
On a designated day of the week, run the mix as
low as feasible and discard after closing. This will
break the rerun cycle and reduce the possibility of
high bacteria and coliform counts.
Properly prepare the cleaning and sanitizing
solutions. Read and follow the 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.
Temperature of mix in the mix hopper and walk-in
cooler should be below 40°F (4.4°C).
Regular Maintenance Checks
Rotate scraper blades to allow both sides of the
knife edge to wear evenly. This will contribute to
self-sharpening and help maintain fast, efficient
freezing.
Replace scraper blades that are nicked,
damaged, or worn.
Before installing the beater, make sure that
scraper blades are properly attached over the
pins.
Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and make
sureit is properly cleaned.
Using a screwdriver and cloth towel, keep the rear
shell bearing and the female hex drive socket
clean and free of lubricant and mix deposits.
Dispose of O-rings and seals if they are worn,
torn, or fit too loosely, and replace with new ones.
Follow all lubricating procedures as outlined in
“Assembly” page 6-1.
Check the condensers for accumulation of dirt and
lint. Dirty condensers will reduce the efficiency
and capacity of the machine. Condensers should
be cleaned
monthly
with a soft brush.
Never
use
screwdrivers or other metal probes to clean
between the fins.
Note:
For machines equipped with an air filter, it will be
necessary to vacuum clean the filters on a monthly
schedule.
On water-cooled units, check the water lines for
kinks or leaks. Kinks can occur when the machine
is moved back and forth for cleaning or
maintenance purposes. Deteriorated or cracked
water lines should be replaced only by an
authorized Taylor technician.
