Abstract

A methodology and product or system configurations are provided which allow food to be directly irradiated for cooking applications which involve the impingement of direct radiant energy on food or comestible items. Cooking vessels or cook-packs are used that are optically transmissive in visible or infrared narrow wavelength bands emitted in suitable narrowband cooking or heating systems.

Claims

1. A cookware vessel for supporting a comestible item in an oven cavity, the oven cavity having irradiation arrays that emit visible or infrared irradiation at only desired narrow wavelength bands, the vessel comprising:

a vessel location feature to uniquely orient and position the cookware vessel in the oven cavity relative to the arrays to facilitate irradiation of the comestible for cooking by the arrays,

wherein the cookware vessel is comprised of a material that is transparent at visible or infrared wavelength bands of irradiation used for cooking and wherein the cookware vessel is comprised of plastic material.

2. The cookware vessel as set forth in claim 1 wherein the plastic material is at least one of polyethylene terephthalate (PET), polypropylene (PP), high density polyethylene (HDPE), low density polyethylene (LDPE), polyvinyl chloride (PVC), polystyrene (PS), post-consumer resin (PCR) or Nylon.

3. A cookware vessel for supporting a comestible item in an oven cavity, the oven cavity having irradiation arrays that emit visible or infrared irradiation at only desired narrow wavelength bands, the vessel comprising:

a vessel location feature to uniquely orient and position the cookware vessel in the oven cavity relative to the arrays to facilitate irradiation of the comestible for cooking by the arrays,

wherein the cookware vessel is comprised of a material that is transparent at visible or infrared wavelength bands of irradiation used for cooking and wherein the cookware vessel is configured to facilitate irradiation of the comestible from top and bottom directions.

4. A cook-pack for storing and/or cooking a comestible item in an oven cavity, the oven cavity having irradiation arrays that emit visible or infrared irradiation at only desired narrow wavelength bands, the cook-pack comprising:

a plastic base portion into which the comestible item is placed, the plastic base portion being transparent at visible or infrared wavelength bands of irradiation used for cooking to facilitate heating the comestible by the irradiation emitted by the arrays; and

a location feature to uniquely locate the cook-pack in the oven cavity relative to the arrays to facilitate irradiation of the comestible for cooking by the narrowband arrays.

5. The cook-pack as set forth in claim 4 further comprising a cover comprised of a material that is transparent at the visible or infrared wavelength bands of irradiation used for cooking.

6. The cook-pack as set forth in claim 5 wherein the cover is one of a lid and a film.

7. The cook-pack as set forth in claim 4 wherein the cook-pack is comprised of at least one of polyethylene terephthalate (PET), polypropylene (PP), high density polyethylene (HDPE), low density polyethylene (LDPE), polyvinyl chloride (PVC), polystyrene (PS), post-consumer resin (PCR) or Nylon.

8. The cook-pack as set forth in claim 4 wherein the plastic base portion includes at least one colorant or marking, the at least one colorant or marking being transparent at the wavelength bands of irradiation used for cooking.

9. The cook-pack as set forth in claim 4 wherein the plastic base portion includes additives raising a coefficient of absorption of the base portion at specific wavelength bands.

10. The cook-pack as set forth in claim 4 further comprising an anti-reflective coating effective at the bands of irradiation used for cooking.

11. The cook-pack as set forth in claim 4 further comprising codes specifying at least one of cooking parameters or oven configuration parameters.

12. The cook-pack as set forth in claim 11 wherein the codes are automatically read.

13. The cook-pack as set forth in claim 11 wherein the codes include locational information.

14. The cook-pack as set forth in claim 11 wherein the codes are used to control which devices of the arrays are turned on, strength or timing during cooking.

15. The cook-pack as set forth in claim 11 wherein the codes are one-dimensional or two-dimensional bar codes.

16. The cook-pack as set forth in claim 11 wherein the codes are radio frequency identification (RFID) tags.

17. The cook-pack as set forth in claim 4 further comprising incorporation of a pressure or steam relief valve.

18. The cook-pack as set forth in claim 4 further comprising geometric shapes of different material for browning or branding purposes.

19. The cook-pack as set forth in claim 4 wherein the location feature positions and orients the cook-pack in a predetermined position in the oven cavity relative to the arrays.

20. The cook-pack as set forth in claim 4 wherein the location feature comprises a portion positioned on the outside of the cook-pack, the portion being configured to mate with a portion of the oven cavity to hold and locate the vessel within the oven cavity.

21. The cook-pack as set forth in claim 4 wherein the cook-pack is configured to facilitate irradiation of the comestible from top and bottom directions.

22. The cook-pack as set forth in claim 4 wherein the base portion is one of a disc and a container with vertical walls.

24. The cook-pack as set forth in claim 4 wherein at least one colorant causes the cook-pack to be at least partially opaque to a human viewer while maintaining high transmissivity in at least one of the wavelength bands of visible or infrared radiation used for cooking.

25. The cook-pack as set forth in claim 4 wherein at least one colorant comprises inks or colorants used as labeling material readable by a human viewer while maintaining high transmissivity in at least one of the wavelength bands of visible or infrared radiation used for cooking.

26. The cook-pack as set forth in claim 4 wherein the location feature is configured to engage with a corresponding feature when placed in the oven cavity to hold and locate the cook-pack within the oven cavity.

27. The cook-pack as set forth in claim 4 comprising compartments for separating food items.

28. A cook-pack for storing and cooking a comestible item in an oven cavity, the cook-pack comprising:

a plastic base portion into which the comestible item is placed, the plastic base portion being transparent at visible or infrared narrow wavelength bands of irradiation emitted by irradiation arrays in the oven cavity that emit visible or infrared irradiation at only desired narrow wavelength bands to facilitate heating the comestible by the irradiation emitted by the arrays; and

a location feature to locate the cook-pack in the oven cavity relative to the arrays to facilitate irradiation of the comestible for cooking by the arrays,

wherein the cook-pack has associated codes or markings specifying at least one of cooking parameters or oven configuration parameters specific to the comestible in the cook-pack.

29. The cook-pack as set forth in claim 28 wherein the codes are sent to a controller for the oven cavity.
