Abstract
This invention includes a method and apparatus for vending frozen foods and also for vending hot previously frozen foods. The invention includes the use of a microwave oven, and a delivery system that maintains the food in an upright orientation so as to prevent spilling of hot foods. An important feature is that the invention does not destroy the microwave containment integrity of the microwave oven and therefore is safer from a radiation perspective.
