Typical Freeze Dried Coffee Specification
Product Description
Freeze dried coffee is produced differently from spray dried coffee.
The coffee is brewed from ground beans and concentrated by partial evaporation and it will be sent to
thefreezer immediately to prevent the large
ice crystals that will cause slow freezing. The frozen coffee is then sealed in a chamber using a vacuum to
remove the air to lower the air
pressure. When the pressure is low, heat is applied to the frozen coffee by radiation or conduction to speed
up the frozen water into gas. After the water content is vaporize, it
is carefully drawn out of the
chamber to condense back into water in a condenser. The vapour that was evaporated earlier is mixed back into
the freeze dried coffee to strengthen the flavour.
Freeze dried coffee available in the market
usually is made with a blend of Robusta & Arabica Coffee. Freeze dried coffee manufacturers are usually
reluctant to disclose thepercentage of
Robusta & Arabica beans used in the production of freeze dried coffee. For sizeable volume, industrial
customers can opt for custom made blend of 100% Arabica or 100% Robusta beans in freeze dried coffee
products.
