CAUSTIC WASHES: SAVE MONEY AND IMPROVE PERFORMANCE WITH AEB'S SPECIAL FORMULATIONS

The fall in energy costs and in the prices of some raw materials that we are witnessing is certainly a good thing. However, this does not detract from the fact that current costs are at least twice as high as they were before 2022.

The adoption of additives to soda ash solutions used for CIP applications and recirculating washes has high economic benefits and helps users achieve sustainability goals.

By enriching solutions with wetting and dispersing components, it is possible to lower:

• the soda concentration required;
• the washing temperature;
• the recirculation time.

The sequestering components present in the additives make it possible to procrastinate or even rule out the need for the acid descaling cycles that are carried out after each caustic cycle if no additives are used. Procrastinating acid washes means eliminating the water consumption required for intermediate rinses. In addition, reducing the concentration of soda ash in a solution results in faster rinses.

THE 3 AEB PROPOSALS FOR SODA SOLUTIONS

ADIX Liquid

Additive for caustic solutions in bottle washings and circuits in C.I.P.

• High cleaning power of washing solutions due to wetting components that significantly lower the surface tension.
• High penetration capacity into organic and mixed-organic contamination.
• Strong dispersing action on the fractions of dirt removed from surfaces, which are incorporated into the washing solution and removed in rinsing.
• Ideal for washing bottles.
• Remarkable anti-foaming capacity.

ADIX Pronto

Liquid caustic soda additive with high cleaning, wetting and sequestering power

• Quick preparation of the formulation by direct addition to the concentrated soda ash when discharged into the tank.
• Sending of additivated soda to all utilities on site avoiding waste and poor additivation.
• Convenient solution when additivation levels of the various utilities are standard.

ADDING OX

Additive for alkaline solutions capable of removing tough organic soils

• Ideal for stubborn contamination often found in the food and beverage industry (e.g. organic aggregates that dehydrate during processing due to heating of surfaces to which they adhere).
• Ability to remove deposits due to the development of active oxygen in solution, which provides the mechanical action required for efficient sanitisation (this is not possible with caustic solutions, even if they are fortified with wetting agents).

WHEN ARE OUR ADDITIVES INDISPENSABLE?

APPLICATIONS WHERE NON-ADDITIVE LYE SOLUTIONS FAIL TO ACHIEVE THE REQUIRED CLEANLINESS LEVELS.

Washing milk or whey evaporators

In multi-acting evaporators, vacuum conditions are used so that water evaporates at temperatures below the 100°C required at atmospheric pressure. As the washing in these systems is carried out under production conditions (as far as the degree of vacuum in the multiple effects is concerned), the temperature of the cleaning solutions is often below 55-60°C. These are temperatures at which the surface tension of the lye solutions is still too high so that these solutions cannot penetrate the milk or whey deposits that have formed on the surfaces during evaporation.

AEB SOLUTION: The addition of ADIX Liquid or ADIX Pronto allows the surface tension to be significantly lowered, achieving the appropriate level of penetration and removal.

Washing pasteurisers and other exchangers in the production of juices, sauces or sauces

The vegetable raw materials that are processed in these types of industries contain many organic salts, particularly calcium oxalate. During heating processes, these salts precipitate on surfaces and, precisely because these are heated surfaces, they progressively dehydrate, forming deposits of high hardness and impenetrability. Caustic solutions, which are better suited to dissolving organic matter, are not able to dissolve these deposits while they act effectively on the other components of the deposits. It was only after years of unsuccessful attempts that it was realised that it was necessary to 'crumble' the salt deposits with oxidising agents added to the washing solutions. Chlorine is the first option and certainly the most effective, but washing often takes place at rather high temperatures and in any case above the canonical 55-60°C considered the line not to be crossed with chlorine-based products, which are also expensive.

AEB SOLUTION: the use of ADDING OX, thanks to its oxidising action released during the recirculation of the caustic solution, allows effective and rapid crumbling of deposits without the risk of corrosion of surfaces.
