5. The food station of claim 4 wherein the collection hatch includes an internal shutter that can be actuated by the control system to selectively deny access from the collection hatch to an interior of the food station while the external shutter is open.

6. The food station of claim 1 wherein internal transport system includes controllable mechanical actuators that translate the end effector in three orthogonal directions, each forming an axis of a Cartesian coordinate system.

7. The food station of claim 6 wherein the controllable mechanical actuators include a first motor for turning a first lead screw to translate the end effector along a first Cartesian coordinate system axis, and second motor for turning a second lead screw to translate the end effector along a second Cartesian coordinate system axis.

8. The food station of claim 7 wherein the controllable mechanical actuators include a belt driven by a third motor for translating the end effector along a third Cartesian coordinate system axis.

9. The food station of claim 8 wherein the first, second, and third motors are stepper motors indexed by the control system.

10. The food station of claim 1 further comprising a user interface, wherein the movement by the internal transport system of the portion container carrier within the food station from the selected cubby enclosure to the collection hatch is prompted by an input to the user interface.

11. The food station of claim 1 wherein the stored information includes a scheduled time for collection of the food portion container by a customer.

12. The food station of claim 11 wherein the stored information includes a key for customer identity verification.

13. The food station of claim 1 wherein the stored information includes a heating instruction corresponding to the food portion container.

14. The food station of claim 1 further comprising communication electronics capable of receiving information via the internet, and the stored information includes information received via the internet.

15. The food station of claim 1 further comprising a label scanner, the stored information including information read by the label scanner from a label on the food portion container.

16. The food station of claim 1 further comprising a plurality of tubes, and wherein the heating system is a hydronic heating system that heats and pumps a first thermal fluid through one or more of the plurality of tubes, and the cooling system is a hydronic refrigeration system that cools and pumps a second thermal fluid through one or more of the plurality of tubes.

17. The food station of claim 16 wherein each of the plurality of cubby enclosures includes its own heating and cooling element through which the first and second thermal fluids can flow.

18. The food station of claim 17 wherein the heating system includes a first plurality of valves that can be controlled by the control system to selectively direct the first thermal fluid through the heating and cooling element of each of the plurality of cubby enclosures.

19. The food station of claim 18 wherein the cooling system includes a second plurality of valves that can be controlled by the control system to selectively direct the second thermal fluid through the heating and cooling element of each of the plurality of cubby enclosures.

20. The food station of claim 17 wherein each of the plurality of cubby enclosures includes an internal fan to force convection within that cubby.

21. A food station comprising:

a plurality of cubbies, each cubby sized to enclose a food portion container, and each cubby including a portion container carrier that includes a front plate with a handle and can hold the food portion container;

a collection hatch large enough for the food portion container to pass therethrough, the collection hatch being externally accessible;

an internal transport system including an end effector that temporarily couples to the handle of the portion container carrier of a selected cubby and controllably moves the food portion container carrier within the food station from the selected cubby to the collection hatch;

a heating system that selectively provides heat to each of the plurality of cubbies independently of the other cubbies, the heating being independently controllable for each of the plurality of cubbies;

a cooling system that selectively removes heat from each of the plurality of cubbies independently of the other cubbies, the cooling being independently controllable for each of the plurality of cubbies;

a control system that controls the heating and cooling of each of the plurality of cubbies and the movement of the internal transport system, the control system including a memory for storing information including information for determining the control of heating and cooling for each of the plurality of cubbies; and

a label scanner, the stored information including information read by the label scanner from a label on the food portion container;

wherein the internal transport system controllably moves the food portion container carrier within the food station from the selected cubby to an internal identification site that includes the label scanner.

22. The food station of claim 21 wherein each of the plurality of cubby enclosures includes an internal temperature sensor that provides feedback to the control system, and the information for determining the control of heating and cooling for each of the plurality of cubby enclosures includes at least heating temperature, schedule, and duration information.
