Spray dried

In the powdered coffee industry spray drying of coffee extract is a widely used drying method which is considered as the most economical drying technique however due to the process conditions often much aroma's are lost.

It has been proven in practice that when a high quality extract is fed into a spray dryer at high concentration, the aroma retention is improved. By using split or double extraction the first extract contains most of the aromas from the coffee extract.

Concentrating this first extract with freeze concentration retains all of these valuable components in the FC concentrate. The remaining extractions increase the yield but contain little aroma and can be easily concentrated by evaporation. Combining these two concentrated streams improves the quality of the spray dried product.
