How is Spray Dried Instant Coffee Made?

If you are interested in purchasing instant coffee, there are two basic methods of preparation available to you: spray dried and freeze dried. Many coffee experts feel that freeze dried coffee is the better product because the preparation method is more accurate and preserves the aromas and essential oils of the coffee itself.

Spray dried coffee is made by processing brewed coffee through spray drying towers so that it can be turned into a powdered form. The coffee is processed through an atomizer that breaks it down into small droplets. The water will be removed from these droplets as they are dried by gases, and the coffee particles will be separated from the water through centrifugal force.

From there, the spray dried coffee is processed with agglomeration, which helps formulate larger particles out of the small particles that can be used to rehydrate for an instant cup of Joe!

How is Instant Coffee Different From Regular Coffee?

If you are a coffee drinker, the odds are that you may feel that it is almost a sin to drink instant coffee. The truth of the matter is that flavors in instant coffee have come a long way, though it is always preferable to have a freshly brewed cup of Joe.

Instant coffee is made by dehydrating coffee grounds, and the preferred method of instant coffee is freeze dried versus spray dried. When instant coffee is spray dried, it is brought to a high temperature to remove moisture from the coffee grounds. This can compromise the flavor of the coffee. If you choose freeze dried instant coffee, it is frozen to remove the moisture, so the final instant coffee product will be more authentic.
