Industrial Conveyor Ovens

Print Plate (SPC) Ovens – Equipment

Pre-Heat or Post-Bake with the same Oven. The Print Plate Oven delivers the energy to the plate at the proper rate with a matched and balanced air flow system. This further reduces annealing and warping, but still provides exceptional uniformity of cure.

Flexibility - The ability to precisely vary time and temperatures provides an extremely broad range of combinations for processing various plate types currently available, as well as those of the future.

Repeatability - The constant conveyor speed and excellent uniformity allows each plate to be exposed to identical conditions.

Productivity - The conveyor oven can provide a continuous flow of properly cured plates because they can be loaded and cured simultaneously.

Precise Control - The convected air heat transfer system eliminates undesirable radiant heat. A thermocouple type proportional instrument responds instantaneously to recirculated air temperature changes. Over-absorption or under-cure are nonexistent.

Quality - SPC ovens have been in service for over two decades and have proven their ability to survive constant duty with minimal maintenance and wear.

Belt Conveyor Ovens & Furnaces

There are five (5) standard types of airflows used in all conveyor ovens: Top-Down, Bottom-Up, Top & Bottom, Horizontal, and Combination. Horizontal and Combination airflow are least common in conveyor ovens, but are used in batch ovens quite often.

Whether the product is conveyed by an overhead conveyor, a flat belt conveyor, or a spindle (chain-on-edge) conveyor, these type of air flows are industry standards and provide various advantages as described hereafter.

These are the three most common types of air flow for conveyor applications. Choosing the best air flow configuration for your application is very important and can make or break the process. However, air flow type is only one of the design parameters important to the success of an oven's performance and Wisconsin Oven will be glad to discuss your specific heat process needs.

Carousel Ovens - Conveyor

A Carousel oven is a simple concept that saves valuable space and allows the product to be loaded and unloaded in the same spot. With multiple layers, the load can become a very dense pack, ideal for small parts that need to be handled individually.

A similar concept is a drum oven as shown in the oven with the door open. Again the load is densely packed and can be rotated during heated if desired.

Strip Cure Equipment

Altera Technologies manufactures web and strip cure ovens, where steel, aluminum, plastic, or paper is processed as a continuous web onto which a coating or paint is applied. An oven, also known as a dryer, is used to cure the coating on the web using convection technology, where heat energy is transferred to the product through forced air. Pressurized duct plenums are typically located above and below the web to direct heated air onto the web through regularly spaced louvers.

Since the web hangs at a catenary as it travels through the oven, the ducts are designed to follow the shape of the catenary to optimize heat transfer. The ducts can also be vertically adjustable to allow final adjustments and fine tuning during commissioning of the equipment at final job site.

Altera Technologies's Oven web dryers utilize multiple zones of control, recirculation and heat, for accurate temperature control under changing conditions. Each zone can be operated at different temperatures to provide optimum cure and maximize line speed. Each zone typically includes its own separate exhaust port, to insure complete removal of all solvents and fumes that are released during the heating process.

Strip cure oven ductwork to direct heated air onto a web of steel or aluminum traveling at 400 FPM. Air impinges from both the top and bottom. The ductwork follows the catenary of the web and is vertically adjustable.
