Abstract

A method is for handling a sterilized food product and includes securing an aseptic fitment to a filling port of an intermodal container including a rigid shell having an elongate shape with opposed closed ends, and at least one frame assembly supporting the rigid shell. The method also includes sterilizing the intermodal container, and aseptically filling the sterilized intermodal container with the sterilized food product through the aseptic fitment. The method may also include sealing the aseptic fitment after aseptic filling. A related intermodal container and filling station are also disclosed.

Claims

1. A method for handling a sterilized food product comprising:

securing a cap-type aseptic fitment to a filling port of an intermodal container comprising a rigid shell having an elongate shape with opposed closed ends, and at least one frame assembly supporting the rigid shell, said rigid shell also having a discharge port therein;

closing the discharge port;

sterilizing the intermodal container;

maintaining the intermodal container in a fixed position while aligning a cap-type compatible moveable aseptic filling head by moving the cap-type compatible moveable aseptic filling head in at least an x-y plane relative to the intermodal container; and

aseptically filling the sterilized intermodal container with the sterilized food product through the cap-type compatible moveable aseptic filling head and the cap-type aseptic fitment.

2. The method according to claim 1 further comprising sealing the cap-type aseptic fitment after aseptic filling.

3. The method according to claim 1 further comprising aligning the cap-type compatible moveable aseptic filling head based upon at least one of optical, mechanical and electrical sensing.

4. The method according to claim 1 further comprising supplying a sterile gas to maintain a positive pressure within the intermodal container during aseptic filling.

5. The method according to claim 1 wherein the sterilized food product comprises a viscous sterilized food product having an absolute viscosity of greater than 500 centipoise.

6. The method according to claim 1 wherein the sterilized food product comprises sterilized citrus pulp.

7. The method according to claim 1 wherein the sterilized food product comprises sterilized fruit or vegetable juice.

8. The method according to claim 1 wherein the intermodal container has a capacity greater than 10,000 liters.

9. The method according to claim 1 further comprising transporting the intermodal container after aseptic filling and subsequently discharging the sterilized food product by opening the discharge port.

10. The method according to claim 9 further comprising maintaining at least one of a desired pressure and desired temperature within the intermodal container during transporting.

11. The method according to claim 10 further comprising recording at least one of the desired pressure and desired temperature.

12. The method according to claim 10 further comprising wireless transmitting at least one of the desired pressure and desired temperature.

13. The method according to claim 1 wherein sterilizing comprises sterilizing using at least one of steam and a chemical sterilant.

14. A method for handling a sterilized food product comprising:

securing a cap-type aseptic fitment to a filling port of an intermodal container comprising a rigid shell having an elongate shape with opposed closed ends, said rigid shell also having a discharge port therein, and at least one frame assembly supporting the rigid shell for transporting in a generally horizontal orientation via at least one of rail, truck, and ship;

closing the discharge port;

sterilizing the intermodal container;

maintaining the intermodal container in a fixed position while aligning a cap-type compatible moveable aseptic filling head by moving the cap-type compatible moveable aseptic filling head in at least an x-y plane relative to the intermodal container;

aseptically filling the sterilized intermodal container with the sterilized food product through the cap-type aseptic fitment and using the cap-type compatible moveable aseptic filling head; and

sealing the intermodal container after aseptic filling.

15. The method according to claim 14 further comprising aligning the cap-type compatible moveable aseptic filling head based upon at least one of optical, mechanical and electrical sensing.

16. The method according to claim 14 further comprising supplying a sterile gas to maintain a positive pressure within the intermodal container during aseptic filling.

17. The method according to claim 14 wherein the intermodal container has a capacity greater than 10,000 liters.

18. The method according to claim 14 further comprising transporting the intermodal container after aseptic filling and subsequently discharging the sterilized food product by opening the discharge port.
