The primary difference between the conventional and convection ovens can probably be summed up by saying one thing: A convection oven is a conventional oven with a fan inside the oven cavity to circulate the hot air. The addition of the fan promotes the movement of heat by convection, and this reduces cooking time. Convection already occurs in the conventional oven, but on a limited basis. The fan kicks the process up several notches. Convection in this case is the transfer of heat from the heat source to the food item by the moving air. Air atoms and molecules pick up heat from the heating elements and carry it around in the oven cavity. The air will then transfer that heat to whatever is in there that is cooler than the heated air. The air then returns to the heat source to repeat the cycle. When thinking this through, it becomes clear that the addition of the fan gives the oven's performance a big lift. There are units on the market what include microwave capability as well, and they add another step of complexity. Microwave cooking to augment conventional thermal cooking adds another dimension to the cooking performance of the appliance.
In a Conventional Oven the Heat source is stationary So there is the possibility of having Hot and Cold spots in the Oven and Overall uneven cooking. A convection oven on the other hand has fans that move the heat around in an attempt to gain a more constant temperature. This causes the food to cook around 20% faster though some say it dries out the food more than a conventional oven
Conventional ovens have the heating source at the bottom of the stove. Convection ovens use fans to assist in blowing the hot air around to cook the food more evenly.
A conventional oven cooks your food with out air circulation. Where as a convection oven has a fan which allows the air to flow around and cooks your food faster and more evenly.
A convection oven moves the air, a microwave does not.
This Cuisinart bread machine has a convection feature making it a faster alternative to the conventional oven.
A convection oven moves the air, a microwave does not.
A microwave uses radio waves to heat food from the inside out, and a convection oven uses heat waves to cook food from the outside in. While they both cook food fairly quickly, the method of a convection oven is much more similar to a conventional oven.
convection warms and convention bake bakes
The difference is in the features. A regular microwave only features the normal microwave functions. However, a convection microwave oven also has a built-in convection oven in it.
Convection ovens have a fan in order to move the heat inside providing faster and more even cooking.
A fan oven or convection oven uses a fan to circulate hot air within the oven; this moving air strips away a thin layer of air which isn't moving surrounding the food being cooked, cooking it more quickly and evenly.
Faster than a conventional oven, slower than a microwave
A conventional oven has temperature controlled by a thermostat and is designed to give an even heat.A wood burning oven takes some practice to control the heat, but gives a pleasant slight smoky flavour to the food, and cooks quickly with a radiant heat. With the right set-up, the oven base of stone gives a good crispiness to the pizza base.
You can do this in either a conventional or a convection oven. If you use a conventional oven, I would rotate the roasting pan half way through the cooking process to compensate for any hot spots in the oven. If you use a convection oven (with the fan), cooking is more even because the fan blows the hot air around the food, but you have to remember to reduce cooking temperatures 50 degrees if you leave the convection function on.
