Title: Method for manufacturing a vending machine for serving extremely cold frozen product and method for distributing same

Abstract: The present invention is generally directed to a method for modifying a vending machine to provide a vending machine for storing product at a temperature no greater than -40 degrees Celsius. The method of the invention includes the steps of replacing an existing refrigeration compressor with a different compressor having a higher compression and replacing an existing refrigerant with a more efficient refrigerant. Then, the length of an existing capillary tube was increased (preferably to approximately 21 inches). Finally, a new thermostat capable of achieving a -40 Celsius set point. In addition, in the preferred embodiment, the pre-existing thermostat was rewired into a safety switch, which is operable to disable the vending machine from dispensing product if the temperature exceeds the set point. A novel business method is also provided; namely a method of manufacturing and distributing ice cream. In accordance with this method, a novelty ice cream product is manufactured to take on a beaded and free-flowing form. This ice cream product is then shipped and distributed through vending machines capable of maintaining temperatures sufficiently cold to preserve the beaded and free-flowing form of the ice cream product.
