Method of treating powder or granulate substances
Abstract
Abstract SUBSTANCES IN POWDER OR GRANULATE FORM ARE TREATED WITH SUBSTANCES IN FLUID FORM BY INJECTING THE POWDER OR GRANULATE SUBSTANCE DOWNWARDLY IN A REACTION CHAMBER INTO A SPRAYING ZONE SUBSTANTIALLY REMOVED FROM THE UPPER END OF THE REACTION CHAMBER AND NEAR AN OUTLET AT THE LOWERMOST END OF THE REACTION CHAMBER WHILE AT THE SAME TIME SPRAYING THE FLUID SUBSTANCE INTO THE SPRAYING ZONE THROUGH A PLURALITY OF PERIPHERALLY SPACED OPENINGS IN THE SIDE WALL OF THE REACTION CHAMBER FROM NOZZLES LOCATED OUTSIDE THE CHAMBER NEAR THE LOWERMOST END OF THE CHAMBER. DURING SPRAYING, AIR IS DRAWN THROUGH THE OUTLET OPENING AND UPWARDLY THROUGH THE CHAMBER WHEREBY THE POWDER OR GRANULATE SUBSTANCE IS CAUSED TO SWIRL IN CLOUD FORMATION WHILE BEING TREATED WITH THE FLUID SUBSTANCE. THE AIR IS DRAWN UPWARDLY AT A RATE TO MAINTAIN THE LIGHTER AND UNTREATED SUBSTANCES IN WHIRLING MOTION AND TO ALLOW THE HEAVIER TREATED SUBSTANCES TO PASS THROUGH THE OUTLET OPENING BY THE ACTION OF GRAVITY.
