GIZZARD PROCESSING DEVICE Filed NOV. 21, 1968 JOHN C. EDWARDQ SR.
United States Patent O 3,579,714 GIZZARD PROCESSING DEVICE John C. Edwards, Sr., 519 Hilltop Drive, Raleigh, N.C. 27610 Filed Nov. 21, 1968, Ser. No. 777,649
Int. Cl. A22c 21/00 US. Cl. 17-11 4 Claims ABSTRACT OF THE DISCLOSURE In abstract, a preferred embodiment of this invention is a gizzard cleaning machine which uses a Vacuum nozzle to remove dirt from split gizzards, uses a vacuum to hold the gizzards on a conveying belt and uses a vacuum to pull the stomach gut into engagement between a pair of skinning rolls.
This invention relates to cleaning devices and more particularly to gizzard cleaning devices.
In the past, various types of gizzard splitting, cleaning and skinning systems have been developed in attempts to automatically achieve these operations while meeting health standards set up by State and Federal agencies.
Through experience, it has been found that a relatively large number of gizzards, particularly in Government inspected processing plants, must be discarded as waste because they are found to have one or more specks of dirt on them. This is particularly true in the fatty portion of the gizzard.
In making attempts to eliminate the residue of dirt, various shapes of water nozzles have been devised to wash the dirt from the split gizzard. These attempts, however, have not been satisfactory for several reasons. One is that covers are required over the spray headers to prevent the dirt and water from being splashed into adjacent processing areas. These covers allow dirt to accumulate above the gizzards being cleaned. When this dirt falls from the cover, the gizzards below are recontaminated. The covers also prevent repairmen from watching the operation of the cleaner so that they may determine what adjustments might be necessary for more efficient operation.
One of several other problems encountered in the use of the prior art machines is that of the gizzards being bruised, torn or otherwise damaged during processing. This is particularly true in devices of the type which use endless, high speed conveyor chains with damaging barbs or projections spaced at intervals thereon for engagingly holding the gizzards as they pass by the various processing stations. Aside from the bruising effects of the barbs, this type of equipment is expensive to maintain due to the high most of manufacture and the short operational life of conveyor chains in a wet environment.
The present invention has been developed after much research and study into the above mentioned problems and is designed to drastically reduce the number of gizzards lost due to contamination and physical damage. In doing this, applicant has also come up with a less complicated unit which is less expensive to build and operate and yet one which functions in a far superior manner with better cleaning and less damage than prior known systems.
It is an object, therefore, of the present invention to provide a relatively flat belt conveyor having at least one opening therein to which a vacuum is applied to hold the gizzard being processed in relative fixed position to said belt.
Another object of the present invention is to provide a vacuum cleaning means for removing the dirt from the interior of a split and spread open gizzard.
A further object of the present invention is to provide a gizzard washing station immediately following a vacuum cleaning station along the path of a gizzard conveyor belt.
3,57,714 Patented May 25, i971 Another object of the present invention is to provide in a gizzard processing device a vacuum gut puller beneath a pair of skinning rolls to more quickly and more readily cause the gut to come into operative contact with such rolls.
An additional object of the present invention is to provide a gizzard cleaning device which includes an endless type conveyor which moves at a much lower velocity than thought practically feasible in prior art devices.
Other objects and advantages of the present invention will become apparent and obvious from a study of the following description and the accompanying drawings which are merely illustrative of the present invention.
In the drawings:
FIG. 1 is a top plan view of the gizzard cleaning device of the present invention; and
FIG. 2 is a side elevational view thereof.
With further reference to the drawings, the gizzard processing equipment of the present invention indicated generally at 11 has a chute or conveying means 12 extending from a load area (not shown) to a point 13 adjacent gizzard conveyor belt 14.
The endless conveyor belt 14 is slideably mounted about the vacuum manifold 18 particularly as seen in FIG. 2. This manifold extends from a position adjacent pulley or drive wheel 15 to rounded end 16. Thus it can be seen as drive wheel 15 is rotated by a motor (not shown) in the direction indicated by the arrow, belt 14 will move around manifold 18 as indicated. A long slot or opening (not shown) is provided under belt 14 so that opening 17 therein communicates between the ambient air and the interior of the manifold.
Spaced slightly below conveyor 14 at the end opposite drive wheel 15 is a more or less conventional, high speed rotating gizzard slicing or splitting blade 20. The power means (not shown) to operate this blade may be of any conventional type such as an electrical motor.
A wire or bar type gizzard opening and spreading means 21 has one end disposed adjacent blade 20, the other end adjacent pulley or drive wheel 15. For convenience, the pair of gizzard opening and spreading wires 21 are mounted on the sides of the vacuum manifold 18.
A vacuum nozzle 22 and its associated vacuum line 23 are located adjacent the point where the gizzard opening means will have completely spread the split gizzard being conveyed by belt 14. The vacuum line 23 is, of course, operatively attached to a suitable vacuum source (not shown).
Further along the path of travel of belt 14, as indicated by the arrows in the drawings, is a final rinse nozzle 24 and its associated water line 25. This nozzle, of course, is so located as to spray into the evacuated interior of a spreadopen gizzard.
Although a multiplicity is shown in the drawings, at least one opening 26 in the imperforate belt 14- is provided. The belt, of course, should be composed of a relatively friction less material so that it easily slides in sealed contact with the vacuum manifold 18.
Located adjacent to and below drive pulley 15 is a pair of gizzard skinning rolls 27 of the general type disclosed in applicants co-pending application, Ser. No. 672,033, filed Oct. 2, 1967, and operates in the manner therein described.
Briefly stated, the stomach gut connected to the gizzard hangs down between the feed means 30 as the skinning rolls are meshingly counter rotated (by means not shown). To aid and assure that this gut is engaged between the grooves of the feed means, a vacuum nozzle 28 and its associated vacuum line 29 are located immediately below and adjacent to such rolls. A suitable vacuum source (not shown) should, of course, be provided in operative connection with the vacuum line.
An alternative to using skinning rolls having a feed means similar to that shown at 30 would be to make this area smooth and of approximately the same diameter as the shaft portion 27'. By mounting the vacuum nozzle 28 at the angle shown in FIG. 2, the gut or a portion of the skin of the gizzard would be pulled downwardly and in the direction of the skinning portion 27" of the skinning rolls 27. This would substantially reduce the cost of manufacturing the rolls and is considered to be just as efficient if not more eflicient than the present method using the feeding portion or spirals.
In actual operation of the device of the present invention, a multiplicity of gizzards (not shown) are placed in the chute 12 and moved to point 13. Because the belt 14 is constructed of a relatively frictionless material such as plastic or the like, the gizzards will stop at this point. As belt 14 is moved in the direction indicated by the arrows in the drawings, one of the holes or openings 17 will pass point 13. At the same time such opening passes over vacuum manifold '18. This causes a suction through opening 17 which gently engages the gizzard and holds the same over the moving opening.
The gizzard is then carried by belt 14 pass the rotating blade 20 which slices it open. Since the opening and spreading wires are close together at their end adjacent blade 20 see FIG. 1), they both pass into the slit opening of the split gizzard. As belt 14 continues to move, the gizzard is spread open by the diverging wires 21 until it reaches a full spread position in area 31. Adjacent this area is a vacuum nozzle 22 which sucks the dirt from the inside of the gizzard. This vacuum evacuation has a great advantage over the water cleaning devices of the prior art in that rather than splattering the dirt from the gizzard it is sucked therefrom into a suitable disposal area (not shown).
As the gizzard being held by the vacuum on belt 14 continues to move pass the vacuum evacuation station it passes above (as oriented in the drawings) a final rinse nozzle 24 which will clean any residue of dirt left by the vacuum nozzle 22. This final rinsing does not require near as much water nor as high pressure to accomplish the desired result as is necessary in the prior art devices where water nozzles are used for the entire cleaning process. Also since the water hits the open gizzard from the bottom thus deflecting it downwardly, the undesirable splattering and dripping inherent in the prior art devices is eliminated.
As opening 26, with its vacuum held gizzard, passes beyond the end 18' of manifold 18, the vacuum grip is broken. The gizzard then drops from the belt onto the feed means of the skinning rolls 27. The vacuum nozzle 28 sucks the stomach customarily found on gizzards into the area between the grooves of such feed means 30 and assures that such gut remains in this area until it is meshingly gripped between the spiraled gear portions of such rolls. Once the gizzard has been skinned, a deflection means (not shown) will force it off the rolls and into either a container (not shown) or another conveyor means (not shown) for additional handling.
From the above, it is obvious that the present invention has the advantage of providing a more etficient yet less expensive gizzard conveying, cleaning and skinning device than has heretofore been possible. The present invention also has the advantage of being more efi'icient in obtaining consistently higher quality processed gizzards.
The terms above, below and so forth have been used herein merely for convenience in the foregoing specification and in the appended claims to describe the gizzard processing device and its parts as oriented in the drawings. It is to be understood, however, that these terms are in no way limiting to the invention since the device may obviously be disposed in different positions when it is actually operated.
The present invention may, of course, be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive and all changes coming within the meaning and equivalency range are intended to be embraced herein.
