Freeze dried coffee is a high quality crystallized form of instant coffee which is created, as the name suggests, through cold processing.
Common to both spray dried and agglomerated, there are three main manufacturing stages: extraction, concentration and drying. To extract, fresh roast and ground coffee is put into a series of percolation columns, typically 5-10, in which hot water and pressure are applied to the grounds to yield an extract with approximately 20% soluble coffee solids, and the balance water.
Concentration of the coffee extract can be done in various ways. The most commonly-used methods for freeze dried coffee are freeze concentration, crio-concentration or heat evaporation, depending on the quality desired. Once concentrated, the thickened extract enters a freezing chamber for rapid freezing. Subsequently, the crystallized frozen particles are dried through the sublimation process in a freeze-drying tunnel, where the water is removed.
Enabled by the cold conditions that are used in processing freeze dried coffee, many of the important volatiles and aromatics in coffee remain, yielding the highest quality instant form, which typically commands a premium price.
