Deodorization solutions for fats and oils 3 Deodorization is an absolute necessity in processing edible fats and oils. How efficiently it is done determines what you can achieve in your processing operations as a whole, in terms of removing odours, pigments and volatile substances. In this specialist field, Alfa Laval deodorization solutions are uniquely effective – quite simply a cut above all else. At Alfa Laval, we don’t just make do with traditional deodorization thinking – we develop new and better ideas that later set the standard for the whole industry. Impacting the heart of the deodorization...

4 Deodorization solutions for fats and oils Removing undesirable elements When processing edible vegetable oils and animal fats, it is crucially important to remove any undesirable compounds that can affect flavour, odour, stability and colour. Deodorization is a vacuum steam distillation process in which steam is passed through such oils at very low pressure and relatively high temperature in order to remove any such substances still present after the preceding processing stages. Essential for top-quality fats and oils processing Beginning with deaeration Before heating the oil, air must be...

Retention section Stripping section Alfa Laval SoftColumn Scrubber 6 Deodorization solutions for fats and oils Traditional versus modern In the traditional deodorization approach, the stripping of volatiles and heat bleaching are carried out simultaneously. However, this means that the oil is at higher temperatures for longer and that volatile substances are present throughout the treatment process. In the modern Alfa Laval SoftColumn deodorization concept, on the other hand, the two parts of the deodorization process are kept separate. This ensures much better control of the process and fewer...

8 Deodorization solutions for fats and oils Deodorization solutions for fats and oils 9 More than the sum of the parts A complete Alfa Laval SoftColumn deodorization solution consists of four modular sections.

Stripping section Oil flows evenly down the structured packing in a thin film while steam flows counter-currently....

The retrofit payback The Imcopa soybean oil refinery in Brazil decided on an upgrade path to tackle very high steam costs, plus problems with poor heat recovery in the company’s existing plant. Benefiting from the Alfa Laval retrofit concept, Imcopa upgraded an existing deodorizer as well as installing a new neutralization and bleaching line, plate heat exchangers, mixers and a PX 95 separator. This enabled the company to boost refinery capacity from 400 to 600 tonnes per day. This retrofit strategy, combined with Alfa Laval heat transfer technologies, enabled Imcopa to reduce overall production...
