Continuous process ovens (or conveyor ovens) are batch ovens that repetitively operate with a specific product traveling through them. The conveyor belt moving through the oven has a job to do and keeps on doing that job until the product is complete.

Low energy output, cost savings and consistent temperature gradients can be achieved with recirculated hot air ovens.

Companies have many choices when it comes to conveying methods to move a load through an oven. Factors to consider when selecting a conveying system include the product configuration, weight, oven temperature and desired process flow.

A company in the transportation industry will use a natural-gas-fired conveyor oven with a maximum temperature of 500°F (260°C) to cure contoured plastic parts.

A manufacturer of iron cookware ordered a conveyor oven that will be used to cure a proprietary coating at 475°F (246°C). Lewco Inc. will design and develop the continuous curing oven, which will be rated for a maximum operating temperature of 500°F (260°C).

Two fuel-fired conveyor ovens with a maximum operating temperature of 250°F (121°C) will be used by an equipment integrator for drying various parts. A multi-level, multi-conveyor design was required.

A manufacturer of foundry supplies will use a large conveyor oven to dry ceramic fiber products. The oven, which is rated for a maximum operating temperature of 500°F (260°C), was built and delivered by Lewco Inc.

Intended for laboratory testing and low volume production applications, Model D-100 is equipped with a 16" (40 cm), 1625-W square infrared heater that achieves temperatures to 750°F (400°C). The compact infrared conveyor dryer can be placed on tabletops or wheeled utility carts with tops as small as 24" (61 cm) square.

Thermal Product Solutions shipped a Gruenberg vertical conveyor oven to the manufacturing industry. The operating temperature is 270°F (132°C) while the maximum temperature is 400°F (205°C).

Designed to be used for curing rubber parts, No. 998 is a 450°F (~232°C) gas-fired, vertical conveyor oven. Workspace dimensions measures 68 x 74 x 121”, and 400,000 BTU/hr are installed in a modulating natural-gas burner to heat the oven.
