Abstract

An apparatus for enrobing a product portion can include at least one polymer spray head adapted to create at least one flow of polymeric fibers to produce at least one polymer enrobing zone and a conveyor system adapted to move at least one product portion from at least one position below at least one polymer enrobing zone and to at least one position above at least one polymer enrobing zone to drop each product portion through one or more polymer enrobing zones a plurality times at different orientations to enrobe each product portion with polymeric fibers.

Claims (29)

1. An oral product comprising:

microcrystalline cellulose;

nicotine; and

a porous pouch containing the microcrystalline cellulose and the nicotine, the porous pouch including,

11. The oral product of claim 1 , wherein the polymer is mouth-stable.

12. The oral product of claim 1 , wherein the polymer is hydrophilic.

13. The oral product of claim 1 , wherein the filler is a colorant.

14. The oral product of claim 1 , wherein the porous pouch is seamless.

15. The oral product of claim 1 , wherein the nicotine includes tobacco-extracted nicotine.

16. The oral product of claim 1 , further comprising:

a flavorant.

17. The oral product of claim 16 , wherein the plurality of fibers include the flavorant.
