Ovens have progressed greatly over the last two centuries from just a lighted fire and roasting food over a fire to huge, conveyor-based, automated mechanical systems. As a result, Ovens have come a long way from their early roots as something more than just fire-burning food. Today’s Oven is much more than just a big metal pot that roasts at high temperatures. It is now a device that combines many different functions, such as defrosting, heating, drying, draining, cleaning the inside of the oven, among other things. The evolution of the Oven has led towards fully automated systems, whereas earlier devices were not fully automated.
