2000 Coenen FEECO Integrating Cooling and Drying Systems
The Fluidized Cooler Breeching includes a sloped fluidized bed, which can provide primary or supplemental/secondary cooling of dryer products. As a primary cooler, the system will lower the temperature of the product to a point that is safe to transport and safe to store. It will be designed as part of the dryer discharge breeching. This system is much smaller and more energy efficient than a rotary cooler. As a supplemental cooler, the unit can be installed in either the dryer or the rotary cooler discharge breeching. It can supplement the cooling when the existing system is overtaxed. The cooler can be adapted existing equipment and plant layout. The cooling air can be recycled back to the dryer combustion chamber as make-up air to lower the burner fuel requirements.
