Abstract
An automated vending machine that can be selectively configured to include one or several temperature zones. A single refrigeration system and universal interior allows easy and economical assembly into a one, two, or three temperature zone machine. Thermal breaks and dividers are used to partition zones, when needed. The basic vending machine cabinet, dispensers, and controls are not changed between configurations. In one aspect, a universal air duct can be used for all three configurations, with minor changes.
