Abstract
An oven using one or more quartz halogen tungsten lamps or quartz arc bulbs capable of producing radiant energy of which a significant portion is in the visible light range of the electromagnetic spectrum to pop popcorn whereby visible and near visible radiation directly impinges onto corn kernels. Radiation sources can be positioned around the corn kernels and the inner walls of the oven are preferably highly reflective to reflect light energy onto the kernels. The kernels travel down a tube shaped cooking chamber by a forced air stream. When the corn pops, the highly reflective and very light popped corn is removed via the air stream which stops the cooking process.
Claims13
A method of popping kernels of corn comprising the steps of:
- moving corn kernels by an air stream in an elongated radiation chamber and impinging radiant energy onto the kernels in said chamber, the radiant energy including a significant portion of energy in the near visible and visible ranges
- whereby when the kernels pop and their volume to weight ratio increases drastically the popped kernels are accelerated by the air stream out of said chamber.
Apparatus for popping kernels of corn comprising, in combination:
- an elongated radiation chamber having an input end and an output end, air stream means for creating an air stream to move corn kernels in said radiation chamber toward said output end, means for injecting corn kernels in the air stream, and means for impinging radiant energy onto the kernels in said chamber, the radiant energy including a
- significant portion of energy in the near visible and visible ranges;
- wherein the radiant energy impinging onto the kernels has sufficient intensity that before the kernels reach the output end of said chamber they have received sufficient radiation to pop whereby the volume to weight ratio of the kernels increases drastically and the popped kernels are accelerated by the air stream out of said chamber.
