What is the use of a hot air oven?

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…
One of the reasons a microwave oven gets hot while in operation is because of hot air blown through the cavity (the cooking area). The magnetron (the microwave generating device) gets hot in operation, and a fan blows air through the cooling fins of this special device to keep it cool. That air gets hot, and is forced through the cavity to exit the oven on a side opposite that where it is drawn in…
How can one measure the temperature of hot air oven should i check it hanging thermometer in it through measument soket provided or keeping water in it and dipping thermometer in it through soket?
If you ever want to measure a temperature above 212 degrees, you're better off hanging the thermometer into the air in the oven. Since it's a hot-air oven, you want to measure the air. If it were a hot-water oven, you might prefer to measure water. But even then, what are you gonna do above 212, when the water goes away and all you have in there is steam ??
Pizza in an oven recieves heat by radiation from the hot metal casing, and the burner, and by conduction from the air. Convection only heats fluids; so the air around the pizza (which is cooled by it) flows in convection currents, and interracts with hotter air. The pizza is heated faster because of convection heating taking place, but is not heated by it direction.
A convection oven blows hot air in circulation patterns to speed cooking times and improve browning and texture results while keeping the oven at the correct temperature. A standard oven uses hot coils (electric) or fire jets (gas) to slowly heat the entire interior box of the oven to a certain temperature.
A typical electric oven has a heating element, a length of metal that acts as an electrical resistor. As electrical current passes through, the heating element becomes hot. The oven will either be a convection oven or not. A non convection oven relies on the heating element warming the air, and this in turn warms the food. A convection oven uses circulating air inside the oven. Circulating the air causes faster heat transfer from the…
A convection oven has a fan installed - to circulate the hot air that builds up. The use of the fan means the oven doesn't create 'cold spots' and thus the food cooks evenly. This speeds up cooking time - making the oven more cost-effective. A 'regular' oven has no fan, and thus has uneven temperatures throughout the cooking compartment.
A convection oven contains a fan that a regular oven does not. This fan blows the air around inside the convection oven, setting up artificial convection currents that cause the temperature of the air throughout the convection oven to equalize, eliminating hot and cold spots that may be present in a regular oven. Convection ovens can usually bake or roast faster than regular ovens and do it more evenly.
