What is the D Carousel Dryer? The D carousel dehumidifying dryer produces hot, low-dew point air that removes moisture from hygroscopic plastics. The dryer pulls warm, moist air from a drying hopper and pumps it through dehumidifying desiccant. The dryer then heats the air to the drying temperature you selected and circulates it through the material in the hopper. The dryer’s three-tank, closed-loop design ensures a continuous supply of hot, dehumidified air while preventing contamination from m

How It Works The D carousel dryer achieves continuous, closed loop drying by passing air simul- taneously through two heaters and three tanks of molecular sieve desiccant. THE PROCESS (DRYING) CYCLE The process blower pulls moist air from the top of the drying hopper. The air pass- es through the process filter (and optional aftercooler, if installed) into the dryer’s desiccant tank, where moisture is removed. The now dry air moves through the process heater, where it is heated to the drying tem
