Abstract

An apparatus, and method for cooking and smoking food items and a smoked product produced by the inventive method. The inventive apparatus preferably comprises (a) an oven including a belt-type conveyor, for continuously conveying food items through the oven, and a circulation system for circulating a cooking medium in the oven such that the cooking medium contacts and cooks the food items and (b) a smoke generation and delivery system for delivering smoke to the circulating system such that the smoke contacts the food items along with the cooking medium. The inventive method preferably comprises the steps of (a) continuously conveying food items through an oven and (b) delivering smoke into the oven such that the smoke contacts the food items. The oven used in the inventive apparatus and inventive method is preferably an indirect-fired oven. The smoke most preferably contacts the food items in an impinging manner.

Claims

1. An apparatus for smoking food items, said apparatus comprising:

an oven including

conveying means for continuously conveying said food items through said oven,

circulating means for circulating a cooking medium in said oven, and

impingement means for contacting said food items with said cooking medium in an impinging manner; and

adding means for adding smoke to said cooking medium such that said smoke contacts said food items along with said cooking medium,

wherein said circulating means is operable for delivering said cooking medium and said smoke through said impingement means and onto said food items in said impinging manner at a velocity effective for accelerating the rate at which said food items are cooked and smoked.

2. The apparatus of claim 1 wherein said oven is an indirect-fired impingement oven.

3. The apparatus of claim 1 wherein said conveying means comprises a belt-type conveyor.

4. The apparatus of claim 1 wherein:

said circulating means comprises blowing means for blowing said cooking medium, said blowing means having an inlet and

said adding means is operable for delivering said smoke to said inlet.

5. The apparatus of claim 4 wherein said apparatus further comprises smoke generating means for generating said smoke and wherein said blowing means is operable for creating a vacuum at said inlet which will draw said smoke from said generating means.

6. The apparatus of claim 5 wherein said adding means includes boosting means for boosting the delivery of said smoke to said inlet.

7. The apparatus of claim 1 further comprising heating means for indirectly heating said cooking medium.

8. The apparatus of claim 7 wherein said heating means comprises a burner which will produce a combustion product and wherein said burner is operable for indirectly heating said cooking medium such that substantially none of said combustion product will contact either said cooking medium or said food items.

9. The apparatus of claim 8 wherein said burner will indirectly heat both said cooking medium and said smoke.

10. The apparatus of claim 1 wherein said circulating means continuously recirculates said cooking medium and said smoke through said impingement means.

11. The apparatus of claim 1 wherein said impingement means comprises a plurality of impingement nozzles through which said cooking medium and said smoke are blown by said circulating means.

12. An apparatus for smoking food items, said apparatus comprising:

an oven including

conveying means for continuously conveying said food items through said oven and

circulating means for circulating a cooking medium in said oven such that said cooking medium contacts and cooks said food items; and

adding means for adding smoke to said cooking medium such that said smoke contacts said food items along with said cooking medium,

said circulating means comprising blowing means for blowing said cooking medium, said blowing means having an inlet,

said adding means being operable for delivering said smoke to said inlet,

said apparatus further comprising smoke generating means for generating said smoke,

said blowing means being operable for creating a vacuum at said inlet which will draw said smoke from said generating means, and

said adding means including boosting means for boosting the delivery of said smoke to said inlet.

13. An apparatus for smoking food items comprising:

an oven;

impingement means, in said oven, for contacting said food items in an impinging manner with a cooking medium;

adding means for adding smoke to said cooking medium such that said smoke will contact said food items along with said cooking medium;

a blower; and

conduit means for conducting said cooking medium and said smoke from said blower to said impingement means,

said blower being operable for blowing said cooking medium and said smoke through said impingement means and onto said food items in said impinging manner at a velocity effective for accelerating the rate at which said food items are cooked and smoked.

14. The apparatus of claim 13 wherein said impingement means comprises a plurality of impingement nozzles.

15. The apparatus of claim 13 further comprising conveying means for continuously conveying said food items through said oven.

16. The apparatus of claim 13 wherein said blower is operable for continuously recirculating said cooking medium and said smoke through said impingement means.

17. The apparatus of claim 13 wherein said adding means comprises:

a smoke generator and

second conduit means for conducting said smoke from said smoke generator to said blower.

18. The apparatus of claim 17 further comprising a second blower disposed in said second conduit means.

19. The apparatus of claim 13 further comprising a burner in said oven for indirectly heating said cooking medium such that combustion products produced by said burner will not contact said food items.

20. An apparatus for smoking food items comprising:

an oven including

conveying means for continuously conveying said food items through said oven,

circulating means for circulating a cooking medium in said oven such that said cooking medium contacts and cooks said food items, and

heating means for heating said cooking medium such that no fuel combustion products produced by said heating means directly contact and mix with said cooking medium and

adding means for adding smoke to said cooking medium such that said smoke contacts said food items along with said cooking medium,

wherein said circulating means is operable for continuously recirculating said cooking medium and said smoke through said heating means and into contact with said food items.

21. The apparatus of claim 20 wherein said cooking medium is air.

22. The apparatus of claim 20 wherein said oven is an indirect-fired spiral oven.

23. The apparatus of claim 20 wherein said oven is an indirect-fired impingement oven.

24. The apparatus of claim 20 wherein said circulating means is a blower.
