Abstract

An apparatus for portioning meat includes a base unit, controlling means, first drive means mounted on the base unit, a casing mounted on the base unit, second drive means that cooperates with the first drive means to rotate the casing, and a pressing member dividing the casing into at least two chambers, an in-feed chamber and a pressing chamber. The pressing member is rotatably mounted between the base unit and a top plate, so as to be off-center with respect to the casing, substantially closer to the pressing chamber than the in-feed chamber, such that the pressing member has freedom to move in direction substantially perpendicular to the off-center direction. The apparatus also includes an ejecting device mounted on the base unit, a portioning plate receiving the meat ejected from the pressing chamber, a position adjustable bottom piece, and a cutting means, positioned between the pressing chamber and the portioning plate.

Claims

1. An apparatus for portioning meat comprising:

a base unit,

a top plate,

a controlling means,

a first drive means mounted on the base unit,

a casing mounted on the base unit, the casing having a center and further comprising;

a second drive means that cooperates with the first drive means for rotating the casing, and

a pressing member dividing the casing into at least two chambers, the at least two chambers being an in-feed chamber and a pressing chamber,

the pressing member being rotatably mounted between the base unit and the top plate by a hinging arrangement, so as to be positioned within the casing off-center with respect to the center of the casing, and thereby closer to the pressing chamber than the in-feed chamber, such that (i) the pressing member is rotated along with the casing by the casing'"'"'s walls so as to orbit the center of the casing when the first and second drive means cooperate to rotate the casing 180°

, and (ii) the hinging arrangement causes the pressing member to glide within and with respect to the casing as the first and second drive means rotate the casing and the pressing member rotates around the hinging arrangement and orbits around the center of the casing, to thereby change the pressing member'"'"'s relative position within the casing so that the in-feed chamber becomes a new pressing chamber and the pressing chamber becomes a new in-feed chamber, thus producing a pressing force between the pressing member and the new pressing chamber in the casing,

an ejecting device, mounted on the base unit, for ejecting through an opening in the top plate meat from the pressing chamber,

a portioning means for receiving the meat ejected from the pressing chamber, the portioning means further comprising;

a portioning plate,

third drive means for operating the portioning plate,

a position adjustable bottom piece, wherein the adjustable bottom piece is automatically adjusted to optimize the yield of the meat,

a cutting means, positioned between the pressing chamber and the portioning plate, wherein the meat is placed in the in-feed chamber, the in-feed chamber becoming the new pressing chamber and the pressing chamber becoming the new in-feed chamber, when the first and second drive means rotate the casing 180°

, due to the off-center rotatable mounting of the pressing member within the casing.

2. The apparatus according to claim 1, wherein:

the casing is rotatable about its center, while

the pressing member rotates about its own center inside the casing,

wherein during said rotation the pressing member glides within said casing changing its position within the casing from the one position within the casing to the other position within casing, thereby creating the pressing force which causes meat placed into the in-feed chamber to be pressed into a shape determined by the walls of the new pressing chamber of the casing and the pressing member.

3. The apparatus according to claim 1, wherein the controlling means comprises a computer which generates output signals to control the adjustable bottom piece of the portioning means and the position of the ejecting device.

4. The apparatus according to claim 1, wherein the ejecting device comprises:

a rod,

an end piece, and

first longitudinal drive means,

wherein the end piece is fasten to one end of the rod and the first longitudinal drive means is fastened to the other end of the rod.

5. The apparatus according to claim 3, wherein at least one of the output signals is/are used to control the first longitudinal drive means for the ejecting device.

6. The apparatus according to claim 1, wherein the adjustable bottom piece comprises:

a rod,

an end piece, and

second longitudinal drive means, and

wherein the end piece is fastened to one end of the rod and the second longitudinal drive means is fastened to the other end of the rod.

7. The apparatus according to claim 1, wherein at least one of the output signals is/are used to control the second longitudinal drive means for the adjustable bottom piece.

8. A method of using the meat portioning apparatus according to claim 1, the method comprising the steps of:

loading the meat into the in-feed chamber of the casing through an opening in the in-feed chamber,

rotating the casing 180°

so that the pressing member glides within the casing from one position within casing to another position within casing so that the in-feed chamber becomes the new pressing chamber, whereby the meat is compressed between the new pressing chamber of the casing and the pressing member, the compressed meat taking on the shape determined by the walls of the new pressing chamber and the pressing member,

ejecting the meat compressed in the new pressing chamber into the portioning means using the ejecting device, the thickness of the ejected portion being adjusted by means of the position adjustable bottom piece,

slicing meat extending from the new pressing chamber and filling the portioning plate of the portioning means,

when a portion has been cut from the meat extending from the pressing chamber, rotating the portioning means 180°

, to thereby bringing an empty portioning plate under the pressing chamber to receive a next cut portion of the meat extending from the new pressing chamber,

bringing the newly cut portion out from underneath the pressing chamber, and

ejecting the newly cut portion out of the portioning plate by the means of an ejecting device onto a conveyor, which transfers cut slices from the portioning apparatus,

the controlling means being comprised of a control computer for use in controlling the operation of the portioning apparatus.

9. The method of using an apparatus according to claim 8, wherein the casing rotates about its center, and the pressing member rotates along with the casing when the first drive means and second drive means cooperate to rotate the casing 180°

, causing the pressing member to glide within the casing from the one position within casing to the other position within the casing, thereby causing the meat to be pressed into the shape determined by the walls of the new pressing chamber and the pressing member.

10. The method of using an apparatus according to claim 8, wherein the in-feed chamber is loaded with the meat from the top, while the meat is ejected through the bottom of the new pressing chamber into the portioning plate.
