it's a fan inside an oven, used to circulate the hot air. It's generally found in
a convection oven.
A gyrolfo oven is an oven that is fan assisted.
A fan oven is an oven that circulates hot air using a fan to cook food evenly and quickly. This differs from a conventional oven, which does not have a fan and relies on natural convection to distribute heat, leading to potential uneven cooking.
400 degrees Fahrenheit is approximately 204 degrees Celsius in a fan oven.
For temperature times with a fan oven, you need to subtract about 10 degrees from the conventional oven time given. So, for 160 degrees F in a conventional oven, you would set a fan oven at 150 degrees F.
In a fan-forced oven, 180 degrees Celsius is typically equivalent to 160 degrees Celsius in a conventional oven. The fan in a fan-forced oven circulates hot air, allowing for more even cooking and often reducing cooking times. As a result, recipes may need to be adjusted slightly when using a fan-forced oven.
A convection oven.
Convection oven.
This would depend on the design of the convection oven, but you can usually hear or even feel if the fan is on.
The temperature in the oven and on all sides of the food stays even so the food cooks the same from all directions.
200 degrees Celsius is equivalent to 392 degrees Fahrenheit in a fan oven.
662 degrees Fahrenheit.
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.
