How is freeze-dried coffee made, and what does the name mean? We will consider these issues in this article.

How to sublimate coffee?

This unique coffee drink powder production technology can also be called “freeze-drying”. First, the prepared concentrate is strongly cooled. The ice crystals are then subjected to vacuum dehydration. Why sublimate coffee? First of all, then, in order to preserve the natural substances contained in the grains, to provide a delicate taste and aroma of the final drink. This is the reason for the high cost, which distinguishes freeze-dried coffee (the brands under which it is produced have practically no cheap analogues). The energy intensity of production also affects the cost.

Why sublimate coffee, and how does it affect its taste?

The above technological process allows you to bring the aroma and taste of the drink as close as possible to that made from grains. As you know, the latter is the standard of aromatic coffee. But its daily brewing in a Turk (especially if you like to indulge yourself with this drink several times a day or often receive guests) takes a lot of time. BUTWith the help of technologies that allow you to sublimate coffee, you can have at your disposal a high-quality semi-finished product, no less fragrant.

Once again about making

The photo shows a machine that allows you to freeze a decoction of coffee beans to obtain an ice block, which is subsequently dehydrated and crushed.

As you can see by looking at the finished coffee particles, they are irregularly shaped. This is precisely because crushing makes them so. By the way, freeze-dried is not the only coffee that is made from beans. It should also be mentioned powder and granular. They are also varieties of instant coffee. Powder is made from raw grains, fried and crushed, from which soluble particles are extracted using special equipment. To do this, you need a unit that allows you to supply hot water under high pressure. Before obtaining the final product, the extracted substances are filtered and dried. The production of granulated coffee is generally the same, but has one more additional step - dumping particles of soluble powder into small lumps using a steam jet.

Benefits and harms

All the properties that bean coffee has are almost completely preserved in freeze-dried coffee. Unfortunately, some not entirely useful features are preserved. As you know, coffee can increase blood pressure and is not very useful for people prone to tachycardia. Yes, and a completely he althy person, nutritionists do not recommend drinking more than two small cups of thisdrink per day. Coffee (including freeze-dried) is very useful for those who are accustomed to intense mental activity, as well as those who want to lose weight. After all, it perfectly speeds up all metabolic processes and helps burn excess calories.
