Abstract

Claims (26)

1. A process for making a chewing gum product, said method comprising the steps of forming a powder blend comprising a gum base into the desired shape of said chewing gum product within a die platen of an apparatus and applying radiofrequency energy from said apparatus to said shape within said die platen for a sufficient period of time to soften said gum base to fuse said shape into said chewing gum product.

2. The process of claim 1 , wherein said radiofrequency energy has a frequency of from about 1 MHz to 100 MHz.

3. The process of claim 1 , wherein said powder blend comprises nicotine or a salt thereof.

4. The process of claim 1 , wherein said powder blend comprises a pharmaceutically active agent.

5. The process of claim 1 , wherein said powder blend comprises from about 30 to about 70 percent, by weight, of said gum base.

6. The process of claim 1 , wherein said powder blend comprises from about 40 to about 70 percent, by weight, of said gum base.

7. The process of claim 1 , wherein said process further comprises coating said chewing gum product.

8. The process of claim 1 , wherein said process further comprises adding a second powder blend to said forming cavity wherein said second powder blend is different from said powder blend.

9. The process of claim 8 , wherein said second powder blend comprises an amorphous carbohydrate polymer.

10. The process of claim 1 , wherein said process comprises the steps of:

(i) introducing said powder blend into a forming cavity within said die platen;

(ii) compacting said powder blend by introducing at least one forming tool into said die platen with sufficient force such that the shape of the chewing gum product is formed;

(iii) applying said radiofrequency energy to said shape within said forming cavity to form said chewing gum product; and

(iv) removing said chewing gum product from said forming cavity.

11. The process of claim 10 , wherein said process further comprises the step of cooling said chewing gum product in said die prior to removing said chewing gum product from said die.

12. The process of claim 10 , wherein said at least one said forming tool emits said radiofrequency energy to said shape.

13. The process of claim 10 , wherein the die platen emits said radiofrequency energy to said shape.

14. The process of claim 10 , wherein said powder blend is compacted using an upper forming tool and a lower forming tool, and at least one of said upper forming tool or lower forming tool emits said radiofrequency energy to said shape.

15. The process of claim 10 wherein said process further comprises adding a second powder blend to said forming cavity prior to said step of applying radiofrequency energy to shape, wherein said second powder blend is different from said powder blend.

16. The process of claim 1 , wherein the surface of said chewing gum product is further exposed to infrared energy wherein the majority of the wavelength of said infrared energy from about 0.5 to about 5 micrometers.

17. The process of claim 10 , wherein said powder blend comprises nicotine or a salt thereof.

18. The process of claim 10 , wherein said powder blend comprises from about 30 to about 70 percent, by weight, of said gum base.

19. The process of claim 10 , wherein said powder blend comprises from about 40 to about 70 percent, by weight, of said gum base.

20. The process of claim 14 , wherein said powder blend comprises nicotine or a salt thereof.

21. The process of claim 14 , wherein said powder blend comprises from about 30 to about 70 percent, by weight, of said gum base.

22. The process of claim 14 , wherein said powder blend comprises from about 40 to about 70 percent, by weight, of said gum base.
