Abstract
The invention provides a vending machine for cooling food products. The vending machine includes a housing defining an interior. The vending machine also includes a plurality of holding members substantially thermally isolated from one another and disposed in the interior. Each of the plurality of holding members includes inner and outer hollow members telescopically engaged with one another to define an inner cavity with an opening operable to communicate an individual food product and an outer cavity with an inlet and an outlet spaced from the inlet. The vending machine also includes a refrigeration system disposed outside of the interior and fluidly communicating individually with each of the outer cavities to cool each of the inner cavities.
