Spray Drying Instant Coffee & Soluble Drink Powders
How a spray dryer turns coffee, tea and juice extracts into fast-dissolving instant powders, using a low outlet temperature to protect aroma.
Instant coffee, tea, juice and soy-milk powders are made by spray-drying a liquid extract into a fine, fast-dissolving powder. The key is to remove the water quickly without driving off the aroma.
The drying challenge
- Aroma is volatile — too much heat strips the flavour and aroma compounds.
- Fast dissolving required — the powder must reconstitute almost instantly.
- Liquid extract to be turned into a stable, storable powder.
Why spray drying fits
- Low outlet temperature. Holding the outlet around 80–90°C removes water while protecting aroma.
- Fast-dissolving powder. The porous, fine particles dissolve markedly faster than tray-dried product — a soluble coffee can dissolve in around 5 seconds rather than 15.
- Continuous, large-scale centrifugal-atomizer operation suits beverage production.
- Stable and storable — turning a liquid extract into powder extends shelf life and cuts shipping weight.
