Abstract
Machines having multiple heat zone cooking surfaces for producing popcorn and other types of expanded foods are disclosed herein. In one embodiment, a kettle assembly for popping corn includes a popping surface having a first heat zone adjacent to a second heat zone. In this embodiment, the first heat zone is configured to receive a plurality of unpopped corn kernels, and heat the unpopped corn kernels to a first level. The second heat zone is configured to receive the unpopped corn kernels from the first heat zone, and heat the unpopped corn kernels to a second level, higher than the first level. In one aspect of this embodiment, the kettle assembly can include a first heating element positioned at least proximate to the first heat zone, and a second heating element positioned at least proximate to the second heat zone. The first heating element operates at a first temperature, and the second heating element operates at a second temperature, higher than the first temperature.
