The final drying furnace has a chain conveyor system and will be used to completely remove the remaining moisture contained in the capsules, after the chemical dosage, papering and anvil pressing processes are completed. After the drying process, cooling is carried out in the exit section of the tunnel. Drying and cooling processes are carried out by using water with a circulation system to safely transport the capsules, which have gained explosive properties, through special plates. The plates first pass through the hot stations and then through the cold stations.
