Gas Fired Shrink Wrapping Oven used for Packaging of Auto Batteries
Wisconsin Oven's model Top Flow/G-CM10220, a 500°F rated gas fired convection oven, is designed and manufactured to shrink fit a plastic protective bag over automotive batteries. These pre-printed protective bags replace the need for expensive boxes.
A special ductwork design is used to direct the airflow vertically down, to ensure the shrink wrap forms properly onto the battery bodies. Sample batteries and shrink wrap bags were sent to our facility so the customer could approve the process and equipment performance before the shipment.
The oven features a 14" wide flat wire conveyor belt with special pedestals to carry the batteries through the oven at speeds ranging from 10 to 40 FPM. The conveyor speed is adjustable through a variable frequency drive. The heated chamber is 13' long x 1'3" high (above the conveyor belt for the product). There is a 7'0" conveyor load extension and a 4'0" unload conveyor extension. Illuminated E-Stop buttons are located on each end of the oven. Three (3) access doors, complete with explosion relief latches, are provided on the side of the shrink wrap oven for ease of access and maintenance.
This convection oven is constructed with 4" tongue & groove panel assemblies, 20 gauge aluminized steel on the interior (including the duct and duct materials), and 20 gauge carbon steel exterior (painted with a heat resistant air-dry enamel after the equipment is assembled).
The burner is rated at 500,000 BTU per hour and the direct driven recirculation blower is rated for 7,000 CFM at 7 1/2 HP. The air is supplied to the work chamber through a fully adjustable supply duct located above the work chamber. The air flows vertically downward over and past the product, and then is collected in an adjustable return duct located below the belt conveyor and the structural conveyor slide bed.
The NEMA 12 control enclosure is free-standing (for remote mounting by the customer), and includes a main power disconnect switch. The temperature of the oven is controlled through a micro-processor based digital instrument from Honeywell. Over-temperature protection is provided by a DIN rail mounted Barber-Colman instrument. Door mounted pilot lights indicate control power on, safe guards met, conveyor on, purging, burner on, excess temperature, and a flame relay fault when illuminated.
This oven configuration is also available with gas catalytic or electric infrared heaters, either as a combination oven (convection and IR), or infrared only. Depending on the application, product configuration, dwell time, and production rate, infrared can be a space saving alternative.
Other options that are available include: customized chamber sizes, batch systems, full PLC control, data acquisition systems, alternative heating methods (propane, electric, steam, etc.), and complete "turn-key" systems.
