A convection microwave is an appliance that combines the quick cooking of a microwave with the browning, crisping and cook-through ability of a convection oven. Instead of cooking the food from the inside out like a regular microwave, a convection microwave can brown and cook the outside of the food.
Regular microwaves emit energy that bounces around the inside of the machine until it comes into contact with food. When this occurs, the energy causes water molecules to become excited, create heat and thereby cook the food. Convection technology uses a fan to create movement of heat that cooks food from the inside out. This technology allows users to cook items that would be cooked too quickly and unevenly in a regular microwave.
