Freeze Drying Coffee : A Better Way to Make Instant Coffee

Freeze Drying Coffee : A Better Way to Make Instant Coffee

Freeze-drying is a key stage in instant coffee production. Coffee beans are first roasted and ground, then dissolved into hot water. By this process coffee flavour, aroma and colour are extracted from the coffee grounds, and a highly concentrated liquor is obtained (generally the coffee solution is about 15–30% coffee by mass at the end of this extraction process).

Spray Freeze Drying - Ultrasonic Liquid Spray

Spray Freeze Drying - Ultrasonic Liquid Spray

Spray freeze drying is a technique wherein an atomized liquid spray is sprayed into a cryogenic medium, and the spray droplets are quickly frozen. Once frozen, these frozen droplets are lyophilized (freeze-dried) to remove the frozen solvent and leave particles behind. This technique can be used as an alternative to conventional spray drying for thermo-sensitive compounds …
