DTI-1462 Drying Conveyor Oven
Customer directive
This customer is a global technology company that specializes in specialty glass, ceramics, and related materials and technologies used for industrial and scientific applications. The product being dried in this application are ceramic substrates used in emission control systems. The product characteristics dictate a vertical top down airflow, as well as temperature and humidity control throughout the process. Conveyor extensions on the entrance and exit ends accommodate an automated loading process and a manual unloading process. Differential pressure transmitters mass air flow and velocity sensors provide process air feedback to correlate to existing machinery.
Description
Custom designed and coated conveyor slats convey the substrates through the oven. The slats allow vertical top down airflow to dry the part and the coating prevents any damage to the part. Multizone humidity and temperature control dry the part at a controlled rate to prevent cracking of the ceramic product. Differential pressure transmitters are used to control the mass flow rate of air across the product. A rotary brush on the exit end cleans any debris that might stick to the conveyor slats, and a pneumatic take up on the entrance end maintains proper tension on the conveyor to account for thermal expansion.
