First, let's first understand how the Mini Spray Dryer Machine works. The device looks like a giant sprayer, but it's actually a high-tech device. In the process of making milk powder, liquid milk is converted into tiny particles by spray dryers, which form the basis of milk powder.
So, how is milk powder made by spray dryer? First, fresh milk is fed into a special spray chamber. This spray chamber has a tiny nozzle that sprays the milk into tiny droplets through high-pressure air. These tiny droplets evaporate quickly in the spray chamber to form small particles.
The magic of the spray dryer is that it can quickly evaporate the water in the liquid milk in a very short period of time, leaving only milk powder particles. This is because the internal temperature of the spray dryer is very high, usually above 150°C, and it also has a powerful fan system that can quickly transfer hot air into the spray chamber to speed up the evaporation process.
Through this rapid evaporation process, the powdered milk particles change from liquid to solid and retain the taste and nutritional content of the milk. This is one of the reasons why milk powder can be preserved for a long time without going bad. Of course, in addition to milk powder, spray dryers are also widely used to make other powdered foods, such as coffee powder and cocoa powder.
Spray dryers not only have important applications in the food industry, but also play a role in other fields. For example, in the pharmaceutical industry, spray dryers are used to make pharmaceutical powders for easy storage and administration.
