Abstract

Dans une installation de revêtement, le dispositif d~alimentation en produit pulvérulent est refroidi en permanence pour éviter la détérioration de la poudre qui pourrait être causée par une température trop élevée. L'air de fluidisation de la poudre contenue dans le réservoir (1) est un air froid et sec. Un échangeur de chaleur (30) alimente un circuit en boucle fermée comprenant une chambre annulaire de refroidissement (32) et un serpentin (33) placé sur le trajet de la poudre. L'axe de la vis sans fin peut aussi être refroidi.
