The reactor is equipped with a double jacket, and a triple jacket for en‐ sure a good insulation.
The stirring, the granulation and the drying are done in the same tank.
The stirring with the three‐blade system allows to mix the powders and the disperser allows to break to biggest mass during and after the moistening.
A vacuum pump ensure the unit pressure reducing for allows the water evaporation at low temperatures in order to not degrade the active materials, and in this way allows the pellet drying.
