Mixer granulator dryer

The reactor is equipped with a double jacket, and a triple jacket for ensure 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 themoistening.

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.
