Because making coffee yourself many do not have the time and patience, a wide popular instant version of the drink. The latter will be discussed in this article. Let us consider what is different from granulated or freeze-dried coffee.
Freeze dried coffee – instant beverage that is produced by the technology of «dry freezing». For its manufacture is roasted and finely milled, then the resulting coffee «dust» is brewed in a closed sealed container about three hours. Vapor from the tanks is discharged through special pipe. With him gone and the grains contained in essential oils, which are then retrieved with the use of specific technologies. Digested coffee mass is subjected to rapid freezing in a vacuum, during which it goes out all the moisture. The dry product is broken into particles and impregnated grains extracted from essential oils. With such a complex and delicate technology cooking freeze-dried (or frozen) coffee is characterized by rich flavor and aroma. In the line of instant beverages in this category it is considered the most qualitative and natural.
Granulated coffee – soluble powder, compacted into pellets by steam treatment. Method of preparation of the drink is called «spray-drying». First the grains are cleaned, then roasted and crushed to particle size of 1.5-2 mm. the Next stage is extraction of soluble matter. To do this, place the ground coffee is processed supplied under pressure by hot water for 3-4 hours. The resulting mass is cooled and filtered, removed insoluble and resinous substances. Dried with hot air, the powder is transformed into lumps under the influence of steam. The use of this production technology leads to the fact that the resulting product almost retains the properties of natural coffee. Because long-term heat treatment of raw material it practically loses its rich color and smell, is added to the powder different dyes and artificial flavors.

Thin refined aroma of the drink gives natural essential oils.
The difference between freeze dried coffee granulated from is that the latter is made more coarse spraying. During prolonged heat treatment of the raw material, it almost completely loses its useful properties.
