Abstract
Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks. Some machines include a refrigeration system to cool food or drink in a pod. Some machines include an evaporator of the refrigeration system, the evaporator including an inlet port to receive refrigerant and an outlet port to discharge refrigerant. Some machines include a processor controlling the refrigeration system. In some examples, the refrigeration system is operable to apply a freezing cycle to the food or drink in which refrigerant flows through the evaporator exchanging heat from ingredients in the pod to the refrigerant causing a temperature difference between an evaporator inlet temperature and an evaporator outlet temperature.
