DTI–1417 Dual Oven System AFR/Barrier/Film Applicator
Customer directive
Our customer wanted to place the products on an indexing conveyor that would move the product into the heated chambers for process. On the Pad Oven the heated air is forced through the insulation pad with a vertical down airflow. The Barrier Oven has forced air from the above and below because the product is impermeable to air passing through it. The airflow design provides efficiency in regards to process time and uniformity.
Description
The DTI-1417 provides a vertical up and down airflow to heat this particular product. The design velocity accounts for the pressure drop through the product to provide an efficient process. The systems conveyors provide a stable surface to support the product and is open to allow process air to flow freely through the product. The design of the conveyors allow the customer to load and unload product easily and the belts travel approximately 8 feet in just 6 seconds to move into and out of the heated chamber quickly. The oven system design does not required any special foundations or floor pits for installation. The oven and the transfer conveyor system are installed on an existing plant floor requiring no special modifications. The control system includes PLC control of the cart, ramp and soak temperature profile controls, starting sequence for all components and flame safety systems. All functions are controlled from the operator HMI (touch screen) and multiple recipes can be stored for future use for various product requirements. The entire system is fully assembled and factory tested for operational verification prior to shipment.
