## 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

### Claim 1

An apparatus for enrobing a product portion comprising:
a) 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
b) a conveyor system adapted to move at least one product portion from at least one position below at least one polymer enrobing zone 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 of times at different orientations to enrobe each product portion with polymeric fibers,
wherein said conveyor system is adapted to move at least one product portion from at least one position below a first polymer enrobing zone to at least one position above the first polymer enrobing zone to drop each product portion through the first polymer enrobing zone a plurality of times.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein said conveyor system is adapted to drop each product portion through one or more polymer enrobing zones a predetermined number of times.

### Claim 3 (depends on 1)

The apparatus of claim 1 wherein said conveyor system is adapted to move each product portion laterally with each drop.

### Claim 4 (depends on 3)

The apparatus of claim 3, further comprising baffles above or below said first polymer enrobing zone to move each product portion laterally between each drop.

### Claim 5 (depends on 1)

The apparatus of claim 1 wherein said conveyor system comprises a conveyor belt adapted to move between a position below said first polymer enrobing zone and a position above said first polymer enrobing zone.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein said conveyor belt comprises a plurality of ridges adapted to inhibit product portions from sliding or rolling backwards on said conveyor belt.
