The powdered form of botanical extract is the most stable and easiest to store. At Greenvit, this process is carried out using spray drying or vacuum belt drying technologies. In spray drying, the product is sprayed as a mist and mixed with a stream of hot air.

Inlet temperature 150-220°C
Outlet temperature 70-110°C
15500 rpm spray disc
Air brush inside the dryer chamber – equipped with filters and heaters. This device removes powder deposits from the walls of the dryer (speed of 2 rpm). The powder which could remain in the dryer is continuously removed from the walls and cone, which eliminates the possibility of burning particles (powder that has been in the dryer for too long can be different color and is easily seen in the bulk);
Pneumatic transport installation – the powder received under the cyclones of the spray dryer is transported by the dried air at a temperature of 40 °C, thus the powder leaving the dryer has a low temperature;

18000 rpm spray disc
Pneumatic transport installation – the powder received under the cyclones of the spray dryer is captured by the dried air at a temperature of 40 °C, thus the powder leaving the dryer has a low temperature
The dryer has three sections, in each section the temperature can be determined independently, as a standard, the first two sections provide the energy that drives the evaporation process, and the third section cools the powder to room temperature, this is especially important in cases of hygroscopic powders;
The feed speed of the belt is also adapted to the product, thus each product can have a minimum residence time inside the dryer.
