Spray-drying – what is it?

In the context of Foodcom S.A.’s operations, “Spray-drying” is a specialized process used for the transformation of liquid or slurry-based substances into dry, powdered form. This method involves atomizing a liquid or semi-liquid substance into tiny droplets and rapidly drying them using hot air or gas. The result is a fine, free-flowing powder that is easier to handle, store, and transport. Spray-drying is widely employed in the food industry to create powdered products like instant coffee, milk powder, and various food additives. It is also utilized in the feed and industrial sectors for similar purposes, allowing for the preservation of product quality and convenience in various applications.
