What Are Roasters?
Roasters are cooking tools used for broiling or roasting foods such as meat or fish.
While ovens utilize convection heat transfer to apply heat evenly through the temperature difference between a solid and the surrounding fluid, roasters employ radiant heat transfer. They emit infrared rays that generate heat upon striking an object. This method is distinct from the convection heat transfer of ovens.
Many roasters are designed to prevent fats and moisture from dripping onto the heating element, producing minimal smoke. In food factories, large-scale roasters often feature conveyor belts to transport items from input to output. Some models allow adjustment of internal temperature and oxygen concentration, which can shorten cooking times and contribute to improved texture in the finished products.
