Spray Drying

In spray-drying the coffee extract is sprayed into a stream of hot air at the top of a tall cylindrical tower. As the droplets fall, they dry, becoming a fine powder by the time they reach the bottom. The powder may then be texturised into granules to facilitate dosage and dissolution. The quality of the aroma and flavour are preserved thank to the very fast drying occurring during this process. Spray-drying is the most
commonly used drying process.
