Arabica Freeze Dried 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).
After filtration, the coffee extract is dried to get the solid soluble coffee. The liquor is frozen to about -40°C to form a thin layer that is then broken into tiny pieces. These granules are then loaded into the freeze-dryer: both batch and continuous plants are used to freeze-dry the frozen product. A batch process is used for low capacities (generally ranging from 50-7,000kg of powder per day), while a continuous process is used for large capacities (generally ranging from 7,000-25,000kg of powder per day).
