Batch ovens are used for different applications such as in the food industry for baking, dehydrating products and also for drying food items for them to be manufactured and packed. In other industries, batch ovens are used to activate adhesives and to fuse different materials together. These industrial ovens are also used in reheating, laminating and melting materials. In the research industry, Batch Ovens are used for finishing, aging, screening and for sanitizing products. This type of ovens is not used on refractory materials and they generally operate at less than 1,400 degrees Fahrenheit. Normally, industrial ovens like batch ovens are used in large and small volume applications in food manufacturing, electronic and chemical processing.
Batch Ovens are also called cabinet ovens. It comes with racks, trucks or carts and is widely used for curing and drying raw materials. Batch ovens are easy to use and they can be operated and stopped right away depending on the operational requirements. Generally, there are two types of batch ovens; the bench and cabinet industrial ovens and walk-in ovens. Cabinet ovens are suitable for manufacturing small batches while walk-ins are more applicable for processing larger volumes.
Heat Sources of Batch Ovens
There are two main heat sources of batch ovens. They can get their heat supply from either infrared radiation or IR or from convection. Convection heat transfer happens when air goes through a material. The heat transfer happens when hot air gets in contact with a solid item. Batch Ovens that uses convection could transfer heat from 500 to 2,000 BTU/hr-ft2. It could also produce an even temperature in the convection zone.
For infrared radiation, heat transfer takes place when two sources of heat with different temperature levels come into contact with each other. The transfer of heat in infrared radiation ranges from 3,000 to 25,000 Btu/hr-ft2. This increased heat transfer rate speeds up the curing process through the use of transient temperature levels. The speed of heat transfer depends on the radiant sources, exposure time, distance and the thermal capacity of the object. To achieve the right output, there has to be exact and close monitoring of the exposure time and variations should also be minimized.
To ensure that your business would get the right results, choose the type of industrial oven that you are going to use. It takes research and even recommendations from the experts to determine your manufacturing and processing requirements. You can also get your needed industrial oven at a lower price if you would shop around before finalizing your order.
