April 10, 2014 - Featuring overall dimensions of 14 ft 4 in. x 6 ft 6 in. x 30 ft 4 in. and operation from 200–662°F, Model DTI-390 incorporates conveyor belt that accommodates parts across its entire width, ensuring that each part receives equal amount of airflow. System includes curing chamber, cooling chamber, and 5 individual zones of control, each utilizing its own full modulating natural gas burner, circulation fan, and exhaust fan. At belt speed of 2 ipm, Model DTI-390 cures approximately 3,000 parts/hr.

Davron Produces Continuous Conveyor Oven to Improve Curing Cycle Efficiency


Davron Technologies, Inc.
4563 Pinnacle Lane

USA



Press release date: April 1, 2014

Chattanooga, Tenn. – Davron Technologies, Inc. designed and manufactured the DTI-390, a gas-powered continuous conveyor oven that cures automotive brake pads. Prior to purchasing the DTI-390, the customer was curing the product in batch ovens. Batch processing required that parts be stacked in baskets and then loaded into batch ovens. Stacking the parts in baskets restricted airflow, resulting in a longer cure cycle for parts in the center of the oven. The DTI-390 continuous conveyor oven overcame this issue by incorporating a conveyor belt that accommodates parts across its entire width. Each part receives an equal amount of airflow, resulting in a 25-percent faster cure cycle that produces a more consistent cure and that uses less energy.

The DTI-390 features five individual zones of control. Each zone utilizes its own full modulating natural gas burner, circulation fan, and exhaust fan, and is capable of operating between 200° and 662°F. The individual zones of control, along with the modulating burner systems, allow the oven to operate as efficiently as possible. The conveying system utilizes a flat wire belt and a variable frequency drive (VFD) for speed adjustment. The DTI-390 has a curing chamber and cooling chamber in-line. The cooling chamber uses high velocity air to cool the pads to approximately 140°F. The cooling chamber features a cooling supply and cooling exhaust fan. At a belt speed of two inches per minute, the DTI-390 cures approximately 3,000 parts per hour. Airflow within the entire system follows a vertical top-down pattern.

The overall dimensions of the oven are 14’4” wide x 6’6” high x 30’4”long. The dimensions of the curing chamber’s usable interior are 8’10” wide x 0’6” high x 20’0” long. The usable dimensions of the cooling chamber are 8’10” wide x 0’6” high x 8’0” long. The interior of the oven is made out of 16-gauge aluminized steel backed by six inches of eight-pound density mineral wool insulation. The exterior is constructed from 16-gauge carbon steel and is backed by a structural steel frame and finished with high-temperature paint.

Davron designed the DTI-390 continuous conveyor oven based on two criteria provided by the client: the production rate per hour and the estimated time for the curing cycle. Davron did extensive testing to determine the temperature profile needed to meet these requirements and used this information as the basis for the custom design of the DTI-390. At Davron’s recommendation, the customer incorporated multiple zones of independent control to achieve the desired process. Once the continuous conveyor oven was manufactured, Davron did acceptance testing and training with the customer at Davron headquarters in Chattanooga, Tn., prior to shipment.
