3.7 SANITIZING

Sanitizing must be done after the freezer is clean and
just before filling with mix. 

Sanitizing the night before

is not effective.

 However, you should always clean the

freezer and parts after using it.

WARNING

THE UNITED STATES DEPARTMENT OF AGRI-
CULTURE AND FOOD AND DRUG ADMINISTRA-
TION REQUIRE THAT ALL CLEANING AND SANI-
TIZING SOLUTIONS USED WITH FOOD PRO-
CESSING EQUIPMENT BE CERTIFIED FOR THIS
USE. USE “STERA-SHEEN” OR EQUIVALENT.

When sanitizing the freezer, refer to local sanitary
regulations for applicable codes and recommended
sanitizing products and procedures. The frequency of
sanitizing must comply with local health regulations.
Mix sanitizer according to manufacturer’s instructions
to provide a 100 parts per million strength solution. Mix
sanitizer in quantities of no less than 2 gallons (7.5
liters) of 120°F water. Allow sanitizer to contact the
surfaces to be sanitized for 5 minutes. Any sanitizer
must be used only in accordance with the
manufacturer’s instructions.

NOTE

Stoelting, Inc. has found that STERA-SHEEN
GREEN LABEL SANITIZER AND CLEANER does
an effective job of properly sanitizing and cleaning a
soft serve freezer. We therefore include a sample
with each new freezer. For further information read
the directions on the packet. Other products may
be as effective.

CAUTION

PROLONGED CONTACT OF SANITIZER WITH
FREEZER MAY CAUSE CORROSION OF STAIN-
LESS STEEL PARTS.

In general, sanitizing may be conducted as follows:

A. SO218: Prepare 4 gallons (15 liters) of sanitizing

solution following manufacturers instructions, then
pour into hopper, brush hopper walls, and inside of
hopper cover.

SO318: Pour sanitizing solution into the mix con-
tainer, brush mix container, draw tube and pick up
hose. Pump sanitizer from mix containers into the
freezer hopper. Brush hopper walls, hopper cover,
hose adapter and retaining clip.

B. Place the CLEAN/OFF/SERVE switch in the CLEAN

position. Check for leaks around the front door seal.

C. After five minutes, open spigot to drain sanitizing

solution. When solution has drained, place the
CLEAN/OFF/SERVE switch in the OFF position.
Allow the freezer barrel to drain completely.
