Did You Know…

Although instant coffee wasn’t invented until the 1700’s, coffee berries and beans had several uses since 1000 A.D.! - Protein bars- Wine- Fruit drinks

Where coffee began…

Coffee is said to have begun centuries ago while an Ethiopian goat farmer was observing his goats acting full of energy after consuming berries from a coffee shrub. Curious, the farmer had to try the berries for himself and he experienced the same side effects!

Manufacturing Today…

Overtime cultures developed many different ways of roasting and grinding the coffee bean. In order to decrease volume and increase shelf-life, manufacturers began producing instant coffee. Today, the two main instant coffee manufacturing methods are freeze drying and spray drying, with spray drying.

Let’s Focus on Spray Drying…

Spray drying is preferred over freeze drying when producting instant coffee because it is less expensive and the drying times are shorter.

Coffee beans are ground up into small pieces.

Hot, soft water is rinsed over the grounds eliminating unwanted gases.

Cold water is rinsed through them to bring out the bold flavors.

Concentration is increased by putting mixture into a centrifuge, evaporating excess water before cooling the extract.

Remaining gases present a mixture that are altered yet again, the oxygen is eliminated to enhance the flavor and aroma.

To eliminate moisture from the coffee grounds, the mixture is fed through a spray dryer.(Hot air for the spray dryer is generated with an indirect fired air heater, as an indirect air heater doesn’t subject the mixture to the by-products of combustion)

After the dry particles are filtered by the cyclone, they are packaged in a low-oxygen, low-humidity canister to optimize product flavor.
