RODINE 92B: Acid Inhibitor for Food Processing equipment cleaners

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 equipments 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

equipments.

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.
