Abstract

L'air comprimé utilisé pour l'atomisation et le transfert du produit pulvérulent est déshydraté préalablement dans l'une ou l'autre des deux chambres 94, 96 contenant une matière absorbante, disposée en lits, et un réchauffeur 100, 102 Un distributeur 98 à quatre voies branche l'une des deux chambres en utilisation sur le dispositif général de dosage et de mouillage, alors que la seconde est mise en régénération de la matiere absorbante qui est saturée d'eau après utilisation. Ce distributeur peut être commandé par programmateur. La déshydratation préalable de l'air évite les condensations d'humidité sur les parois du dispositif qui sont la cause d'adhérence du produit pulvérulent transféré et qui causent le colmatage du dispositif.The compressed air used for atomization and transfer of the pulverulent product is dehydrated beforehand in one or the other of the two chambers 94, 96 containing an absorbent material, arranged in beds, and a heater 100, 102 A distributor 98 Four-way connects one of the two chambers in use to the general metering and wetting device, while the second is regenerated with absorbent material which is saturated with water after use. This distributor can be controlled by programmer. The prior dehydration of the air prevents moisture condensation on the walls of the device which is the cause of adhesion of the pulverulent product transferred and which causes the device to clog.
