Convection ovens move or transfer heat in a confined space (area inside the oven) through the movements of gasses or liquids. Some of the best convection ovens today use modern and high-tech systems to drive hot air past food in a very fast way.
While a regular oven relies heavily on radiations from walls to heat the food, convection ovens rely on fans to stimulate air circulation in order to drive more convective heat through the food being heated. Because of this, convection ovens can heat food faster than regular ovens. Moreover, convection ovens can also work on lower temperatures than regular ovens while making sure that there are no hot spots and that the food is heated or cooked more evenly.
The two most common types of this kitchen tool are convection microwave ovens and the commercial impingement oven. Convection microwave ovens combine the benefits of a microwave and convection oven. These ovens cook food using the speed of microwave ovens while doing the cooking or heating more evenly using the browning characteristic of a convection oven.
Impingement ovens are often used to cook pizzas because they drive more heat, therefore cooking the pizza faster, while being able to cook the pizza more evenly than traditional pizza cooking tools. The higher heat transfer of convection ovens compared to conventional ovens made it the clear choice for cooking experts.
Some of the best convection ovens are available for just above a hundred dollars which makes them really ideal for home use especially if you are trying to speed-cook everything.
