Once milkstone has formed, it is very difficult to
remove. Without using the correct product and
procedure, it is nearly impossible to remove a thick
layer of milkstone.
(NOTE: general-purpose cleaners DO NOT remove
milkstone.) This can lead to high bacteria counts
and a food safety dilemma.
IT IS BEST TO CONTROL MILKSTONE ON A
DAILY BASIS BEFORE IT CAN BECOME A
SIGNIFICANT FOOD SAFETY PROBLEM.
In addition to food safety, milkstone can cause
premature wear to machine parts which can add to
costs for replacement parts or possibly more
expensive repairs if worn machine parts are not
replaced once they have become excessively worn.
Important Differences Between Cleaning and
Sanitizing
CLEANING vs. SANITIZING
It is important to distinguish between cleaning and
sanitizing. Although these terms may sound
synonymous, they are not. BOTH are required for
adequate food safety and proper machine
maintenance.
CLEANING
·
Is the removal of soil materials from a surface.
· Is a prerequisite for effective sanitizing.
NOTE
An UNCLEAN surface will harbor bacteria that can
defy sanitizing efforts.
Bacteria can develop and resist sanitizing efforts
within a layer of soil material (milkstone). Thorough
cleaning procedures that involve milkstone
removal are critical for operators of frozen
dessert machines.
SANITIZING
·
Kills bacteria.
· Can be effective on clean surfaces only.
· DOES NOT clean or remove milkstone.
NOTE
Using a SANTITIZER on an unclean surface
will not guarantee a clean and safe frozen
dessert machine.
Proper Daily Maintenance:
The Only Way to Assure Food Safety and
Product Quality
Proper daily maintenance can involve a wide variety
of products and procedures. Overall, the products
and procedures fall into three separate categories.
(Please note that this is a brief overview intended for
informational purposes only.)
1. CLEANING – This involves draining mix from the
freezer barrel and rinsing the machine with
water. Next, a cleaner is run through the
machine. Then, the machine is disassembled
and removable parts are taken to the sink for
cleaning.
2. MILKSTONE REMOVAL – Since almost all
cleaners do not have the ability to remove
milkstone, the use of a delimer becomes
necessary. Although this procedure may not be
needed on a daily basis, it will usually follow the
cleaning procedure. It requires letting a delimer
solution soak in the machine for an extended
period of time. Individual parts are also soaked
in a deliming solution for an extended period of
time (more about delimers in Additional
Information).
3. SANITIZING – After the machine has been
cleaned and contains no milkstone, the
machine is reassembled. Then a FDA-approved
sanitizing solution is run through the machine to
kill bacteria. The machine is then ready for food
preparation.
As a recommended cleaner and sanitizer for your
frozen dessert machine, STERA-SHEEN has proven
to be one of the best daily maintenance products for:
· CLEANING – Thorough removal of all solids
including butterfat and milk fat.
· MILKSTONE REMOVAL – Complete removal of
milkstone.
· SANITIZING – FDA-approved no rinse sanitizer
for food contact surfaces.
Additional Information
THE USE OF DELIMERS
A delimer is a strong acid that has the ability to
dissolve milkstone. This type of chemical may
become necessary once high levels of milkstone
have developed. While these products are very
effective for removing HIGH levels of milkstone, they
are not ideal for two reasons:
1. PRODUCT SAFETY – Strong acids are
dangerous chemicals and handling them
requires safety
2. MACHINE DAMAGE – Strong acids will attack
metal and rubber causing premature wear of
parts. The use of a delimer needs to be closely
monitored to avoid damage to machine surfaces
and parts.
