Effective cleaning of equipment
in the food processing industry is required to reduce chances for contamination
of during preparation, processing, storage & serving. Cleaning prevents
attraction of lower life forms like food pathogens, increases equipment life,
boosts employee morale and efficiency and accounts for aesthetic considerations
of consumers. The primary cleaning agent is water; free from disease producing
organisms, toxic metal ions and objectionable taste & odor. But such
quality of cleaning water is hard to achieve and chemicals are tailored to meet
cleaner specifications based on water composition and operation type.
Acid Type Cleaners & Corrosion:
Acid cleaners are used in the
food processing industry for milkstone removal and cleaning equipment like
broth tanks, ingrediators etc. A wide choice of acid type cleaners for mineral
scale removal exist today but organic acids and blends of organic acid type
cleaners and chelating agents have found much popularity in recent times. This
is because they are much less corrosive than mineral acids and alkaline
cleaners. Citric acid and EDTA are frequently used for this purpose owing to a
better pH regulation and less aggressive surface action.
Nevertheless, acid cleaning
chemicals are corrosive to the base metal and are responsible for corrosion
& pitting of surface. Inhibitors for Citric Acid
descaling solution are usually applied at very low concentrations
(1000-3000 ppm) to provide upto 99.8% corrosion inhibition during acid cleaning
processes. Depending on the acid type used, specific corrosion
inhibitors are designed to remove scales and deposits from equipment while
minimizing base metal loss. They are of mostly polymeric origin and act by
forming chelating structures, proving high efficiency as inhibitors in acid
chemical cleaning operations.
RODINE 92B is a blend of
semi-foaming corrosion inhibitors specifically formulated for preventing
corrosion by Citric acid and EDTA based cleaners. It is highly efficient at
protecting metal surfaces such as steel and copper alloys commonly associated
with equipment in food processing and packaging industry. It has been shown to
assist in surface cleaning and descaling actions by acid cleaners without any
pitting or corrosion on metal surface.
With respect to the nature of
industry where rodine
acid inhibitors are used, toxicity issues for inhibitors is of prime
concern & exposure to humans due to improper/inadequate rinsing is a
possibility. Rodine 92B has been designed for such special applications and
contains ingredients generally recognized safe to humans thus suitable for
cleaning of food equipment.
Key product features are:
·
Modifies metal surface to prevent corrosion
·
Excellent wetting properties for better cleaning
·
Enhances cleaning efficiency
Rodine 92B is effective upto a
temperature of 85°C/185°F and can be applied in all types of food processing,
packaging & storage industries as inhibitor for acid cleaning systems.
