Freeze drying coffee machine & equipment to produce instant coffee

By using the freeze drying coffee machine, most of the coffee flavour can be preserved. It’s a high value product and the flavour difference makes it worth it.

Freeze drying coffee is a type of coffee that is produced from freeze drying coffee equipment. It’s a kind of coffee processing that removes any water content from coffee by sublimation. There are two main goals of this process, first is to allow people to prepare hot coffee quickly just by adding hot water, that’s why this kind of coffee more known as instant coffee, the second goal is to extend its shelf life to 2 to 20  years (yes, twenty), and even it it will have indefinite shelf life if stored in freezer although the freshness (taste and aroma) will be long gone.

Freeze drying coffee equipment is a key stage in coffee production. The process of making freeze drying coffee includes various steps. They are: first, lowering the temperature to approximately -40℃. By making the temperature this low, the water content will be frozen. On this process, the pressure in the freeze drying coffee equipment used is also being lowered. That being done, the frozen water’s sublimation will occur. After that the process continued to secondary drying because there’s still water left after the first process, mostly water molecules that aren’t frozen in the first step. In this second step, the temperature will be increased. By the end of this step, the water content left will be extremely low, less than 1%. In this kind of freeze drying coffee processing, the gentle drying conditions as well as the low temperature could avoid color and aroma deterioration as well as nutrient degradation. That being said, this processing is deemed suitable to obtain coffee with high quality.

Once you mix the coffee crystal with the hot water, you could enjoy and sip the coffee afterwards. If you think the strength of the coffee is lacking, you will only need to add more coffee crystals. It is that simple. On the contrary, if you think the coffee is too strong, you will only need to pour more water to the cup. It is that easy. With freeze drying coffee, you don’t need to worry about your coffee going bad. This type of coffee can last for a long time in its container or packages.
