Spray drying instant coffee

Spray drying instant coffee refer to a type of coffee that has been treated with a spray drying process that remove all the water from the coffee beans.

Spray dryers are rapid dryer, drying rate is high. Product quality can be controlled and maintained in drying process. Highly controllable drying systems flow of hot air, droplet speed and droplet temperature can be effectively controlled.

With spray-dried coffee, the texture of the coffee powder is usually very fine for most people. Coffee aroma consists of a complex mixture of volatile compounds, whereas non-volatile compounds contribute to flavors such as sourness, bitterness, and astringency.

Spray drying is achieved by spraying liquid coffee concentrate as a fine mist into very hot, dry air. The droplets are dried in very hot air (approx. from 80 to 180˚C) and evaporate leaving behind the coffee powder.

The spray drying process is very quick and uses high heat. Because of that, the process produces fine and small particles, which results as a powdered form.
