A rotary oven is a type of industrial oven. Industrial ovens are typically large, producing enough heat to bake numerous items at once for commercial use. Industrial ovens are usually either used for baking food products for commercial resale or curing industrial materials.
Non-food industrial ovens, which include rotary ovens, are typically used to cure certain materials that are hardened through heat applications. To that end, rotary ovens are used to raise materials to a high temperature in a continuous, indexed or manual process, in order to accomplish heating applications. Typical heat processing applications performed by rotary ovens include: annealing, lean or cell based manufacturing, pre-heating, shrink fitting and stress relieving.
Materials produced in rotary ovens include: cement, lime, refractories, metakaolin, titanium dioxide, alumina, vermiculite and iron ore pellets. Rotary ovens are also used to roast a wide variety of sulfide ores prior to metal extraction. Rotary ovens rotate the material within the heat chamber, where it may encounter a single or multiple heat zones.
A rotary oven may include optional features like: recirculation fans with high efficiency motors, inert atmospheres, can construction bodies, thermal and regenerative oxidizers, remote capabilities using industrial computer technology, UL or CE certified panels, PE certifications and programmable controls with HMI technology.
Rotary ovens may glean heat from a number of sources, including electricity, LPG, natural gas, fuel oil, steam and other fuel mixtures. Rotary ovens benefit many industries and applications, including aerospace, agriculture, automotive, heavy duty equipment, HVAC, motor, mining and transportation.
Rotary oven manufacturers will accommodate your specifications and standard requirements. Most manufacturers can build or modify your rotary ovens so that they conform to standards like: NFPA, IRI, FM, OSHA, JIC, NEC, UL and CE. Manufacturers may further check for quality through certain assessments, such as assessments for production goals, parts configuration and construction, part mass, temperature profile and in-facility test runs.
They may also test your rotary ovens for performance, accuracy, safety systems, air management and temperature uniformity. Discuss your application, specifications and requirements with potential manufacturers to find the right fit for you. A well-built and well-maintained rotary oven is a treasure.
