RODINE 92B Acid Inhibitor for Food Processing equipment cleaners - 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 equipment.

Metal Pickling: Acids and Inhibitors

Hot rolling processes associated with various metal industries often leave behind inorganic oxide residues on treated metal surfaces. Exposure to moisture also results in rusting of Ferro-Nickel based metal parts. These oxides interfere with further cold processing like polishing, electroplating, painting or enameling. Rust and scale formation is a thin layer of metal oxide on the surface that is mostly removed by chemical cleaning also called “Pickling”.

Pickling is carried out on oxide scaled surfaces of metals with alloy content less than 6%. The ideal pickling solution, known as Pickle Liquor is a 3%-10% solution of Hydrochloric acid (HCl) or Sulfuric acid (H₂SO₄). Hydrochloric acid is chosen over Sulfuric acid because of faster pickling action all the while minimizing base metal loss. It restricts formation of smut and greatly decreases the risk of excessive attacking.  It is also economic as heating expenses needed for sulfuric acid are spared due to possibility of lower temperature pickling.

Metal pickling is essential for thoroughly removing scales and inorganic surface contaminants before applying finishing layers like paint, galvanizing and polishing. The result of the process depends on the type, strength and temperature of the pickling liquor. In order to be economical, it is chosen as a continuous cleaning process by mode of manual/mechanized spraying or dipping in large acid vats. For small scale industries like jewellery making and research laboratories, extensive use of pickle pots is observed. Nevertheless, the corrosive action of diluted pickle acids cannot be ignored. In most cases, there is a significant loss of base metal during cleaning operations. For this reason, Acid Inhibitors are used with the acid solution to reduce base metal corrosion.

Inhibitors are natural or synthetic organic compounds added to acid solutions to reduce metal surface corrosion. They slow or stop the chemical action of acid on the base metal surface.

Inhibitors are essential to:

   Reduce base metal loss

  Protect the surface from pitting attack by excessive pickling or from poor surface condition quality

  Reduce fumes resulting from excessive acid-metal reactions

  Help economize acid consumption without reducing descaling efficacy

  Control the rate of pickling

Rodine Acid Inhibitor is a series of acid corrosion inhibitors designed to serve worldwide standards for acid inhibitors. They are specially synthesized to provide protection to base metals from acidic corrosion effectively. Rodine Acid Inhibitor products inhibit the corrosion of metals against acids like Hydrochloric, Hydrofluoric, Sulfuric, Phosphoric, Sulfamic, and organic acids blends. The most common products underlined in this range include Rodine 213, Rodine 213 Spl, Rodine 31A, Rodine 103, Rodine 103 NF, Rodine 92B, Rodine 130, and many more.

The process is limited to oxides and inorganic scales and contamination by soils, oil, grease, soaps and lubricants need additional processes with the use of Degreasing chemicals. Other limitations of acid pickling include difficulty to handle products because of their corrosive nature, the issue of hydrogen embrittlement popularly associated with some alloy and high-carbon steels, occupational hazards as the reactions produce toxic fumes in the factory shed. To obtain desired descaling, without endangering metal surfaces, acid concentrations and solution temperature need to be monitored quite strictly. Sludge is the ultimate waste product of acid pickling. It contains acid rinse water, metallic dissolved and suspended salts, waste spent acid etc. EPA considers it Hazardous waste and recommends proper treatment before disposal mostly in the form of Lime neutralization.

RODINE 213 - Acid inhibitor for Hydrochloric Acid

Most metal hot working processes tend to leave a discoloring oxide layer or scale on the surface. Deposition of inorganic impurities, stains, rust and scales from ferrous, cuprous, aluminium and precious metal mostly as oxides hinder with further processes like extrusion, rolling and galvanizing. In jewellery making, soldering and annealing processes leave metal oxide residue that prevent polishing of ornaments. Such impurities are cleaned with the help of diluted solution of acids. The method is called pickling and the workpiece is dipped in a vat of acid solution popularly called “Pickle Liquor”.

Hydrochloric acid replaced the commonly used Sulfuric acid as the pickling liquor because it pickles much faster with minimum base metal loss. The aggressive chloride ion in the acid is the key to high efficiency in the cleaning process. It is used for cleaning metals with an alloy content of 6% or less. An acid inhibitor must be added to the pickling solution to prevent the metal from dissolving or becoming pitted. Such a pickling acid solution is called “Inhibited HCL” and is a blend of Hydrochloric acid solution in water (3% to 10%) and an acid corrosion inhibitor which in itself is a blend of organic compounds that adsorb on the metal surface during pickling.

Rodine 213 is a premium organic blend of keto-amine complex substitutes with non-ionic surfactants, alcohol and solvents especially designed to inhibit attack of hydrochloric acid on metal surfaces during industrial operations like cleaning and pickling. It is effective over a wide range of metal surfaces like Iron & Steel, copper and brass. Rodine 213 is a high foaming formulation with a high efficacy at dispersing grease deposits and is ideal for HCL based pickling liquor solutions especially prior to plating.

It ensures metal surface protection during processes involving elimination of lime deposits from boiler and pipework and from evaporating plants, removal of oxide deposits from iron, steel, brass and copper. Rodine 213 is free from chlorinated hydrocarbons and heavy metals like arsenic and lead. It can be synergized with Hydrochloric acid pickling in stipulated concentrations both by circulation method and by soak and rinse method. Rodine 213’s exceptional strength and commendable heat stability makes it an ideal acid inhibitor during enhancement of the pickling process by pre-heating the equipments with the inhibited acid solution. It also acts as a strong acid fume suppressant.

Its key features can be summarized as follows:

·         Modifies  metal surface to prevent corrosion

·         Easy to use

·         Excellent wetting properties for better cleaning

Anionic Polyacrylamide (APAM): Industrial Wastewater Management

Industrial wastewater containing suspended organic solids pose a threat to the aquatic biota when discharged untreated in surrounding water bodies. The issue has become one of dire concern with increasing variation in nature and type of solids associated with the effluent. One promising method to treat such wastewater conveniently is using flocculants to remove the suspended solids before discharging the water. An ideal choice for this is using polymer based flocculants that are cost friendly and easy to use over a wide range of suspended solids.

Flocculation is the process by which individual particles of a suspension aggregate. They consist of anionic, cationic and nonionic polymers of varying molecular weight. They are used to increase the efficiency of settling, clarification, filtration and centrifugation operations. They adsorb on particles and cause destabilization by bridging or charge neutralization. Most common polymer used in water treatment is made from Polyacrylamide. Polymers are given anionic character by copolymerizing acrylamide with acrylic acid.

                                      

Anionic PAM series products are polymer used in water treatment that are water soluble linear chained synthesized polymers that are insoluble in other common organic solvents. They have valuable properties like flocculation, thickening, shear properties, drag-reduction and dispersibility. Thus they are widely used in environmental protection practices for the treatment of industrial wastewater containing suspended matter; mostly coarse with high concentration of positively charged particles under neutral or alkaline pH conditions.

Synthetic polymeric flocculants like APAM have become very popular in industrial effluent treatment owing to their natural inertness to pH changes, high efficiency even with low dosage, and easy handling. They are the widespread choice as waste water treatment chemicals for industries such as Iron & Steel, Electroplate factory, Metallurgical workshops, coal washing etc.

Features:

Criteria	Benefit/Activity
Application	Organic-based wastewater
Treatment ability	Suspended and colloid particles
Treatment Process	Simpler, no pH adjustment needed
Sludge generation	Less sludge produced, may contain monomer residue
Treatment cost	Less expensive
Mechanism	Charge neutralization and concurrent bridging
Removal efficiency	TSS: 100% removal COD: 55% removal BOD5: 23% removal

APAM is most commonly available as Polyacrylamide powder and has been tested to show no toxicity to even sensitive aquatic species even at much higher concentrations than used in industry thus ensuring zero environmental setbacks from tail-end runoffs into natural water bodies.

Drinking Water Chemicals

Water consumable by people and animals is referred to as drinking or potable water. Water might be naturally consumable in nature, like pure natural springs, or might be processed to make the end use consumable. In either way, water security is evaluated with tests which search for possibly unsafe contaminants. Contaminants of drinking water increase day by day and it is necessary to put a check on the same, due to the buildup of toxic chemicals, infectious agents, even trace radioactive hazards. Drinking water quality is a strong determinant of general health. And, to ensure safe drinking water helps in laying the foundation for prevention and control of water-borne diseases.

Common drinking water contaminants include the following:

·         - Chlorine, causing bladder and rectal cancer, even asthma

·        -  Lead enters tap water through eroded pipelines. Lead poisoning brings about learning and developmental disorders

·        -  Giardia, Cryptosporidium sorts of protozoa account for serious flare-ups of GI tract illnesses

Drinking Water Chemicals generally account for the safety and purification of drinking/ potable water. It ranges from potable water disinfection to mineral additives, anything holding the water quality at the maximum.

Reverse Osmosis is one of the finest methods for pure Drinking Water. It is one of the processes where water is forced into a set of semi-permeable membranes under pressure and working against the concentration gradient, water is highly purified, ensuring the removal of most toxins and contaminants which otherwise pollute and hamper the wellbeing of the consumers. But, reverse osmosis comes with a catch of being developing biofouling or scaling issues. And it is necessary to clean and disinfect the same that otherwise hampers the efficiency of the process ergo tampering with the water quality, making membrane cleaners and disinfectants a subcategory of drinking water chemicals.

Drinking Water Chemicals also include the addition of food grade minerals with specific end use, such as sodium bicarbonate for increasing alkalinity, etc.

Next category falling under the same includes the safe sanitation of bottled plants, and jars which holds the most load for water transfer, making it necessary to disinfect the same, otherwise adulterated vessels contaminate the safe drinking water making it unsafe and non-consumable.

Contamination/ tainting can be dealt with the application of Drinking Water Chemicals which are included in the treatment of consumable water for rendering it safe to drink.

Brewery Chemical Products Suppliers - ChemEqual

Cleaning and sanitation are an indispensable part of a brewery that needs to be taken into account throughout the entire brewing process. Cleaning precedes disinfection by expelling natural/inorganic buildups and microorganisms from all the brewing equipment. Sanitation lessens the surface populace of microorganisms subsequent to cleaning and averts microbial development on the distillery gear.

Blending is routinely segregated into nine phases: processing, malting, mashing, lautering, boiling, ageing, molding, separating, and filling. These methodologies truly incorporate the venture of various sorts of hardware isolated into respective systems. Almost all brewery hardware including tanks, fermenters, brewing pots, and lautertuns contain microbial deposits/ residues that must be evacuated at routine interims in consistent operations. Amidst beer production, tendencies of scaling and soiling inside brewkettles, fermentation vessels, pound/lautertuns, heat exchangers, fillers, barrels, sections, and saccharification tanks, reducing the ability of heat exchange and generation of off-flavors, hardware malfunction, ailments and increased downtime.

Brewery Chemicals host a range of specially processed chemicals for use as a cleaner and disinfectant in brewing farms. They aid in cleaning and preparation of Distillery. CIP or Cleaning in Place Systems were first introduced by the dairy business as a method for lessening the labour required for cleaning and purging operations.

One of the primary focal points of CIP systems is that they can recycle and permit the reuse of chemicals and wash water, diminishing its use by as much as half. CIP to a huge extent evacuates human contact with cleaning and disinfecting agents, reducing chemical exposure along these lines reducing human exposure to a minimal. They guarantee an additional reliability owing to evacuate the common human errors in cleaning. Spraying agents are used to apply CIP liquids to the surface being cleaned.

Breweries sanitizers lessen/ reduce the quantity of microorganisms to adequate levels in blending which otherwise carry a ton of risks for toxicity, unflavourable brew, microbial buildups, etc.

Sanitation may be either done physically or with the use of chemical sanitizers.

Physical strategies use either boiling hot water or steam to eliminate microorganisms.

Chemical sterilization includes either submergence in a disinfecting solution or splashing/ wiping the object and permitting it to air-dry. Most common chemical sanitizers include chlorine mixes, quaternary ammonium mixes, hydrogen peroxide, peroxyacetic corrosive, anionic acids, and iodophores.

Common Brewery Chemicals in the cleaning range incude:

·         Caustic based Cleaners that remove organic material from pipelines, preventing the growth of most beer spoiling bacteria

·         Acid Chemcials remove inorganic scales from the brewery systems, mostly descaling chemicals

·         Water Rinsing for before and after chemical introduction in the pipelines.
