Common types of ovens and their temperature range

Common type of ovens

Although there are many different kinds of ovens, these are the most popular ones:

  • Conventional oven: the most basic kind of oven is the conventional oven. They create heat with a heating element, and then radiation transfers the heat to the food. Compared to other oven types, conventional ovens are typically less expensive and simpler to operate. They might not be as effective as other kinds of ovens, though, and it can take longer for food to cook uniformly.
  • Convection ovens: Its function similarly to regular ovens, but they additionally feature a fan to distribute hot air throughout the cooking chamber. Compared to a traditional oven, this aids in cooking food faster and more evenly. For baking and roasting, convection ovens work well because they may assist create crispy exteriors and moist interiors.
  • Microwave Oven: Microwave ovens heat food using microwaves. Electromagnetic radiation, such as microwaves, can permeate food and vibrate the water molecules within. The food is cooked by the heat produced by this vibration. For quickly and easily heating up tiny foods like popcorn, frozen dinners, and leftovers, microwave ovens are highly efficient. However, they are not as suitable for baking and roasting because they can yield uneven results.
  • Toasting Oven: Toasting bread, roasting vegetables, and reheating leftovers are common uses for little countertop ovens known as toasters. They are a good option for those who don't require a full-sized oven or for small kitchens.
