DTI-1539 Drying Conveyor Oven(s)
Customer directive
The customer was processing a saturated block of fiberglass that required approximately 200 lbs of water to be removed. One of the challenges of this process was ensuring that the entirety of the fiberglass block was dried, not only the surface. In order to accomplish this process, a automated blank off system was developed to direct airflow up through the product. In addition to the drying process, product needed to be cooled prior to moving to downstream processes.
Description
The DTI-1539 conveyor oven system features (3) independently controlled zones: (1) electrically heated and (1) ambient cooling. Product is placed onto the customer’s pallet that is then loaded via overhead crane onto the equipment’s indexing conveyor system. Each zone is separated by a vertical door to ensure temperature and airflow uniformity. Sensors stop the pallet accurately so that the mechanical blank off system can seal to the product and direct air through it. The customers part varies in length and width which requires the blank off mechanism to accommodate different sizes. The blank off mechanism utilizes a swinging element and a translating element to accommodate the range of sizes while still sealing to each other.
