Organic Acid Inhibitor Rodine 92B – ChemEqual

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.

NALCLEAN 8940 – HCL Based Cleaner For Food Processing Industry

Food Processing, beverage and dairy industry have recently shown a major interest in Clean-in-Place processes due to increased demands from customers in CIP verification and improvements in hygiene standards, product quality shelf life and microbiological consideration. While microbial contamination requires use of sanitizers and disinfectants, pre-processing like pasteurization etc, removal of mineral scaling, food layering and organic depositions can be easily met with cleaning solutions specifically designed for the purpose.

CIP involves the jetting of surfaces or circulations with an appropriate cleaning solution under increased turbulence and flow velocity.  Cleaning solutions so chosen should be active at contaminant removal from any and all types of surfaces without being corrosive to the materials themselves, non toxic and non-residual formulations that can be easily washed off and do not create issues with ultimate quality of food products produced. CIP easily shortens time for cleaning and often cleaning solutions are recoverable. When incorporated in automatic systems, they allow safe and reproducible results that are economic and product friendly.

The simplest form of non-toxic cleaners are basically blends of mineral acids and inhibitors. Acid circulation and spraying is effective in removal of encrusted proteins and mineral deposits on heat treatment surfaces.  Hydrochloric acid seems to be the easy and convenient choice for CIP processes owing to its quick action and high solubility. It can be used directly to clean or as a neutralizing solution after alkaline wash. It enhances draining and drying of pipelines, better bacteriostatic action and removal of mineral deposits like hard water scale, milk stone, beer stone etc. Typical concentrations in solutions range from 30%-70% that require appropriate dilution before application based on industry, equipment, nature of contamination, topography of surfaces to be cleaned and application methods.

NALCLEAN 8940 is a hydrochloric acid based acid cleaner. Manufactured by Nalco Company, it is a blend of Hydrochloric Acid (30%-60%) as a low foaming cleaning liquid that is slightly brown in color. It is a heavy duty formulation for complete removal of difficult mineral and protein base soils, water scales, corrosive depositions and hard deposits from pipelines, pasteurizers, evaporators, vats, tanks, coolers and other stainless steel equipment normally found in food processing plants. NALCLEAN 8940 has slight pungent odor with a low 1.5 pH, high solubility in water and good thermal stability. It is compatible with an array of metal and non-metal surfaces when used in recommended concentrations, cost effective as its effective even at lower concentrations compared to other cleaners, a good neutralizer for surfaces pre-treated with alkaline cleaners and easily adapts to all CIP application and feeding systems.
