A complete cycle involves heating the oven to the required temperature, maintaining that temperature for the proper time interval for that temperature, turning the machine off and cooling the articles in the closed oven till they reach room temperature. The standard settings for a hot air oven are: 1.5 to 2 hours at 160 °C (320 °F)
Before the oven is used, check to make sure that the oven is still in good working condition. All temperature sensing devices need be operational and should shut off the oven if temperatures exceed there limits. If the oven is not operational, it must be unplugged and labeled with the statement "Defective Equipment" on the surface of the oven. [3]
The standard setting for a hot air oven is at least two hours at 160 °C (320 °F). A rapid method heats air to 463.15 K (190.00 °C; 374.00 °F) for 6 minutes for unwrapped objects and 12 minutes for wrapped objects.
A mechanical convection oven contains a blower that actively forces heated air throughout all areas of the chamber. The flow created by the blower ensures uniform temperatures and the equal transfer of heat throughout the load. For this reason, the mechanical convection oven is the more efficient of the two processes.
