Abstract

A method and apparatus for an extrusion horn including an inner compression chamber having an interior channel extending from an open infeed port to an open exit port, where a top inner surface of the interior channel progressively tapers down with an initial slope having an initial downward taper to a target thickness, then top inner surface abruptly steps to an increased thickness of the channel, and then progressively tapers down with a secondary slope where the secondary slope has a steeper downward taper than the slope of the initial downward taper. An apparatus and method for extruding extrudate through an extruding horn conducive for producing bacon bits and jerky.

First claim

What is claimed is:

1. An extrusion horn apparatus comprising:
a conduit communicably extending between an entry portal and an exit portal, where said conduit having a feeder conduit portion communicably extending from the exit portal and communicably contacting in-line end-to-end a tapered portion communicably extending to the entry portal,
where the tapered portion of the conduit has an outwardly tapered end and an inwardly tapered end where the outwardly tapered end is disposed at an upstream position and abutted with respect to the inwardly tapered end communicably extending toward the exit portal, and
where the outwardly tapered end of the tapered portion of the conduit proximate the inlet portal includes an upper outwardly tapered plate and a lower outwardly tapered plate each extending downstream and tapered outwardly one with respect to the other where a distance between the upper outwardly tapered plate and the lower outwardly tapered plate increases as the upper outwardly tapered plate and lower outwardly tapered plate extend downstream, and where a distance between outer edges of the upper outwardly tapered plate and the lower outwardly tapered plate increases as the upper outwardly tapered plate and the lower outwardly tapered plate extend downstream.

2. The extrusion horn apparatus as recited in claim 1 , where the outwardly tapered end of the tapered portion of the conduit includes a left-side outwardly tapered plate and a right-side outwardly tapered plate each extending downstream and tapered outwardly one with respect to the other where a distance between the left-side outwardly tapered plate and the right-side outwardly tapered plate increases as the left-side outwardly tapered plate and the right-side outwardly tapered plate extend downstream, and where a distance between outer edges of the left-side outwardly tapered plate and the right-side outwardly tapered plate increases as the left-side outwardly tapered plate and the right-side outwardly tapered plate extend downstream.

3. The extrusion horn apparatus as recited in claim 1 , where the exit portal is a slitted exit opening in an exit end of the feeder conduit portion.

4. The extrusion horn apparatus as recited in claim 1 , where the feeder conduit portion is an elongated tubular structure.

5. The extrusion horn apparatus as recited in claim 1 , where the entry portal is a slitted entry opening.

6. The extrusion horn apparatus as recited in claim 1 , where the inwardly tapered end of the tapered portion of the conduit includes an upper inwardly tapered plate and a lower inwardly tapered plate each extending downstream and tapered inwardly one with respect to the other where a distance between the upper inwardly tapered plate and the lower inwardly tapered plate decreases as the upper inwardly tapered plate and lower inwardly tapered plate extend downstream, and where a distance between outer edges of the upper inwardly tapered plate and the lower inwardly tapered plate decreases as the upper inwardly tapered plate and the lower inwardly tapered plate extend downstream.

7. The extrusion horn apparatus as recited in claim 6 , where the inwardly tapered end of the tapered portion of the conduit includes a left-side inwardly tapered plate and a right-side inwardly tapered plate each extending downstream and tapered inwardly one with respect to the other where a distance between the left-side inwardly tapered plate and the right-side inwardly tapered plate decreases as the left-side inwardly tapered plate and the right-side inwardly tapered plate extend downstream, and where a distance between outer edges of the left-side inwardly tapered plate and the right-side inwardly tapered plate decreases as the left-side inwardly tapered plate and the right-side inwardly tapered plate extend downstream.

8. A method of extruding extrudate through an extrusion horn comprising:
extruding and an extrudate through a conduit communicably extending between an entry portal and an exit portal, by extruding the extrudate through a feeder conduit portion of the conduit communicably extending from the exit portal and communicably contacting with an in-line end-to-end relationship to a tapered portion communicably extending to the entry portal, and further extruding the extrudate through the tapered portion,
where the tapered portion of the conduit has an outwardly tapered end and an inwardly tapered end where the outwardly tapered end is disposed at an upstream position and abutting with respect to the inwardly tapered end thereby providing back pressure against the extrudate to improve uniform flow, and
where the outwardly tapered end of the tapered portion of the conduit proximate the inlet portal includes an upper outwardly tapered plate and a lower outwardly tapered plate each extending downstream and tapered outwardly one with respect to the other where a distance between the upper outwardly tapered plate and the lower outwardly tapered plate increases as the upper outwardly tapered plate and lower outwardly tapered plate extend downstream, and where a distance between outer edges of the upper outwardly tapered plate and the lower outwardly tapered plate increases as the upper outwardly tapered plate and the lower outwardly tapered plate extend downstream.

9. The method of extruding extrudate as recited in claim 8 , where the outwardly tapered end of the tapered portion of the conduit includes a left-side outwardly tapered plate and a right-side outwardly tapered plate each extending downstream and tapered outwardly one with respect to the other where a distance between the left-side outwardly tapered plate and the right-side outwardly tapered plate increases as the left-side outwardly tapered plate and the right-side outwardly tapered plate extend downstream, and where a distance between outer edges of the left-side outwardly tapered plate and the right-side outwardly tapered plate increases as the left-side outwardly tapered plate and the right-side outwardly tapered plate extend downstream.

10. The method of extruding as recited in claim 8 , where the exit portal is a slitted exit opening in an exit end of the feeder conduit portion.

11. The method of extruding as recited in claim 8 , where the feeder conduit portion is an elongated tubular structure.

12. The method of extruding as recited in claim 8 , where the entry portal is a slitted entry opening.

13. The method of extruding as recited in claim 8 , where the inwardly tapered end of the tapered portion of the conduit includes an upper inwardly tapered plate and a lower inwardly tapered plate each extending downstream and tapered inwardly one with respect to the other where a distance between the upper inwardly tapered plate and the lower inwardly tapered plate decreases as the upper inwardly tapered plate and lower inwardly tapered plate extend downstream, and where a distance between outer edges of the upper inwardly tapered plate and the lower inwardly tapered plate decreases as the upper inwardly tapered plate and the lower inwardly tapered plate extend downstream.

14. The method of extruding as recited in claim 13 , where the inwardly tapered end of the tapered portion of the conduit includes a left-side inwardly tapered plate and a right-side inwardly tapered plate each extending downstream and tapered inwardly one with respect to the other where a distance between the left-side inwardly tapered plate and the right-side inwardly tapered plate decreases as the left-side inwardly tapered plate and the right-side inwardly tapered plate extend downstream, and where a distance between outer edges of the left-side inwardly tapered plate and the
