Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a meat cutting machine or a cutting method for pork, beef, etc., and more particularly, to efficiently cut meat into a desired shape and size without completely freezing it. It is about technology.

[0002]

2. Description of the Related Art Conventionally, in order to cut meat into a predetermined shape and size, lumpy pork is completely frozen at a considerably low temperature to harden it, and then it is placed in a lying position on a cutting board in a predetermined position. I often relied on the manual work of adjusting the thickness to the weight (in grams) and cutting with a knife. That is, by completely freezing the meat, the shape-preserving property of the meat is ensured and the meat does not lose its shape due to the force at the time of cutting so that the meat can be cut satisfactorily.

Further, in order to cut pork into a predetermined shape and size in the process of making pork cutlet, as shown in the flow chart of FIG. 6, the pork is retained in order to adjust the shape (resin frame).
Or set it on the casing (film of synthetic resin) (# 4
Process) and then freeze at sub-zero 18 ° C. (# 5 process). Then, submerge the frozen pork at a temperature below 5 to allow cutting.
After the tempering (step # 6) where the temperature is raised to about 0 ° C., the retainer or the casing is removed (step # 7). Then, after pressing (# 8 step) to prepare the final shape according to the dish, then performing portion slice (# 9 step) to cut the pork into a predetermined shape, which is complicated and has a large number of steps. Met.

[0004]

In other words, in the prior art, in order to allow pork to be cut with a kitchen knife or a cutting blade without being deformed when it is cut out, the meat is once frozen to provide shape retention. At the same time, in order to enable cutting with a blade, a step of raising the temperature a little and then cutting was necessary. That is, when the meat becomes very hard, it becomes impossible to cut it out with a knife or a cutting blade. In addition, there is a side that the taste of meat is likely to be damaged by the process of completely freezing and then thawing, and there are many complicated processes that increase the manufacturing cost and the manufacturing efficiency is not satisfactory, so it is improved. There was room left for.

An object of the present invention is to provide a cutting machine and a cutting method which can cut meat out easily without requiring a great amount of labor and output and which does not damage the taste of meat and which is inexpensive and has high production efficiency. It is in.

[0006]

[Means for Solving the Problems] [Structure or Method] According to the structure of claim 1, a cylindrical cylinder chamber 1S into which a lump of meat M can be inserted, and meat arranged at an end of the cylinder chamber 1S. Meat M inserted in the outlet 2 and the cylinder chamber 1S
The piston mechanism 3 that can be pressed toward the outlet 2 and the outlet 2
A meat 4 that is cut out from the meat is provided with a cutter 4 that can be cut near the outlet 2, and the shape of the outlet 2 can be variably set.
It is characterized in that a setting mechanism K is provided.

According to a second aspect of the present invention, in the first aspect, a supporting mechanism 5 is provided for receiving the meat M discharged from the outlet 2 on the lower side in the cutting movement direction of the cutter 4, and the supporting mechanism 5 and the outlet 2 are provided. It is characterized in that the cutting action is carried out by the cutter 4 between and.

[0008]

According to a third aspect of the present invention, the outlet 2 is arranged below the cylinder chamber 1S in the first or second aspect ,
In addition, the piston mechanism 3 is configured to press the meat M downward.

[0010]

It should be noted that although reference numerals are given for convenience of comparison with the drawings, it should be clearly stated that the description is not limited to the configuration and method of the accompanying drawings.

[Operation] According to the structure of claim 1, since the meat is inserted into the cylinder chamber and there is no room to move to the surroundings, the meat is forcibly pressed by the piston mechanism toward the outlet at one end. Most of the pressure can be used as a component that pushes out the meat from the outlet, and even if the meat is somewhat soft and has poor self-shape retention and is easily deformed, it can be easily shaped into the outlet shape and discharged from the cylinder chamber. .

Since the meat discharged from the outlet is cut by the cutter near the outlet, the cutter acts on the meat under the pressure by the pressing of the piston mechanism. Even if there is, the cutting force of the cutter will not be lost and the meat will not fall apart, and it will be possible to cut well. In addition, since the shape-retaining effect of the cylinder chamber described above occurs, it is not necessary to completely freeze it as in the conventional case, so the cutting force of the cutter can be reduced and the freezing and thawing steps can be omitted. In addition, the taste of meat can be improved, the process can be shortened, and the cost can be reduced. Furthermore, because the exit shape can be changed and set,
For example, it has a long arc shape, a circular shape, or a large size.
Set the shape and size according to the dish such as small
It becomes possible to disconnect.

According to the second aspect of the present invention, the cutter can act on the meat which is supported by both the outlet and the supporting mechanism in a double-supported state, so that the meat can be cut lighter and more reliably. .

[0015]

According to the third aspect of the invention, since the meat cutting machine is constructed in the vertical direction, what presses the meat toward the outlet is:
Gravity due to the weight of the meat can be added to the pressing force of the piston mechanism, and it is possible to more smoothly and reliably push out the meat and to reduce the driving force of the piston mechanism.

[0017]

[Effect] In the meat cutting machine or the meat cutting method according to any one of claims 1 to 3 , the meat is forcibly pressed and discharged from the outlet in a state where the meat is placed in a cylinder chamber which is a closed space. By eliminating the need to completely freeze at a low temperature, it is possible to save refrigeration energy and improve efficiency by reducing the process and cost reduction, and lightly meat with the shape and size as set while using light force. It can be cut into pieces and the taste of meat can be improved. Also, the basis
Mainly one unit, but various shapes as required
It has the convenience of cutting meat into various sizes.

In the meat cutting machine according to the second aspect, there is an advantage that the meat can be cut more lightly and surely without losing its shape.

[0020]

In the meat cutting machine according to the third aspect , by setting the pressing direction in the vertical direction, the effect of the configuration according to the first aspect can be enhanced.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a pork cutting machine A which is an example of a meat cutting machine. This pork cutting machine A
Is a cylindrical cylinder chamber 1S into which the massive pork M can be inserted.
1, a guide block 2 that is an outlet for pork M arranged at the lower end of the cylinder chamber 1S, and a piston mechanism 3 that can press the pork M inserted in the cylinder chamber 1S toward the guide block 2. And a cutter 4 that can cut the pork M discharged from the guide block 2 directly below the guide block 2, and a mold block that receives the pork M discharged from the guide block 2 on the lower side in the cutting movement direction of the cutter 4. (An example of a mechanism) and 5 are provided.

As shown by phantom lines in FIG. 1, two cylinders 1 are provided in parallel, the movement amount of the cutter 4 is made long over the two cylinders 1, 1, and the piston mechanism 3 is provided.
The guide block 2 and the mold block 5 may be freely switchable to positions corresponding to the cylinders 1 and 1, respectively, and the pork cutting machine A equipped with a plurality of cylinders 1 and 1 may be configured.

The meat insertion hole 5A of the mold block 5 is
The guide block 2 is formed into a substantially arcuate shape suitable for forming a pork cutlet, and is driven by a drive mechanism (not shown).
The working position located below the working position and the discharge position laterally moved a predetermined distance from this working posture [see FIG. 2C] are positionally switchable.

The meat insertion outlet hole 2A formed in the guide block 2 has the same upper end shape (circular shape) as the cylinder chamber 1S and the lower end shape same as the meat insertion hole 5A of the mold block 5. Each of the guide blocks 2 is formed in a substantially long arc shape, and the shape is gradually changed depending on the thickness of the guide block 2.

The piston mechanism 3 has a piston portion 3a having a diameter that fits exactly into the cylinder chamber 1S, a piston rod 3b, and a drive mechanism which acts on this piston rod 3b to move the piston portion 3a up and down. (Not shown).

The cutter 4 is a V-shaped blade cutter having a structure in which a left cutter portion 4L having an inclined blade portion 4a and a right cutter portion 4R having an inclined blade portion 4b are combined. The cutter 4 is laterally advanced by a driving mechanism (not shown) until the standby position retracted from the exit hole 2A of the guide block 2 in plan view [see FIG. 2 (a)] and the exit hole 2A completely in plan view. The position can be freely switched to the cutting position (see FIG. 2B).

Next, the operation of the pork cutting machine A will be described. As shown in FIG. 2 (a), the mold block 5, the cutter 4, the guide block 2, and the cylinder 1 are arranged on the table 6 in this order from bottom to top, and are frozen at 0 ° C. to 1 ° C. below (chilled freezing). The massive pork M in the crushed state in the cylinder chamber 1
It is inserted in S, the piston mechanism 3 is operated, and the piston part 3
The agglomerate pork M is pressed downward by a.

The pork M pressed downward is squeezed by the guide block 2, slightly changed in shape and trimmed, and then discharged downward from the outlet hole 2A. At this time, since the cutter 4 is in the standby position, the pork M that has come out of the outlet hole 2A will not reach the platform 6 until the meat insertion hole 5A of the mold block 5 is reached.
It is in a stable state as it enters.

As shown in FIG. 2B, the cutter 4 at the standby position is moved to the cutting position to cut the pork M between the upper and lower portions of the guide block 2 and the mold block 5. Next, as shown in FIG. 2C, while the cutter 4 is held at the cutting position, the mold block 5 is moved from the working position to the discharging position, and the blower 7 arranged above the mold block 5 is driven, The downwardly directed air is blown to extract the cut pork pieces m from the mold block 5.

Then, when the pork piece m falls by one step to the lower table portion 6a lowered by the air blow, the mold block 5 at the discharge position is returned to the working posture, and then the cutter 4 held at the cutting position is moved to the standby position. By moving back, the cutting process of one cycle is completed. Incidentally, when the cutter 4 is moved back, the massive pork M is pressed again by the guide block 2 into a predetermined shape by the weight of the massive pork M and the pressing force of the piston mechanism 3, and the meat inserting hole 5A of the mold block 5 is formed. When it enters, it returns to the state shown in FIG.

In this pork cutting machine A, the guide block 2
Is interchangeable with the one in which the outlet hole 2A having a different shape is formed, thereby forming a shape setting mechanism K capable of variably setting the shape of the outlet. Also, mold block 5
Also, it is configured to be replaceable with a meat insertion hole 5A having a different shape, and can be replaced according to the shape setting mechanism K.

As a reference, a flow chart of the automatic cutlet cutting process using the meat cutting machine of the present invention is shown in FIG. First, pork as a raw material is prepared (# 1), and an injection for improving meat is performed by injecting pickle liquid which has an action of softening the meat quality or increasing the amount (#).
2). Next, after performing a tumbling process (# 3) for stabilizing and homogenizing the meat quality by performing tenderizing such as cutting muscle streaks, a chilled process (# 4) for cooling to 0 ° C to 1 ° C below zero is performed. To do.

The porridge slice step (# 5) of cutting the lumped pork M in the chilled state into a predetermined shape and size (weight) by using the above-mentioned pork cutting machine A is performed to generate the pork piece m. Sprinkle with bread crumbs (# 6). Then, it is immediately fried in oil to be finished in chilled tonkatsu (fresh tonkatsu) (# 7), or a freezing step (# 8) in which it is frozen at 18 ° C below zero is performed so as to be finished in tonkatsu later, and frozen tonkatsu (# 9) or can be selected.

By the way, in the conventional pork cutlet production process,
Since the frozen pork M around 5 ° C below zero is sliced, the cut pork pieces for pork cutlet are almost completely frozen, and it is difficult to put them in oil and fry them in pork cutlet without thawing. Therefore, I had no choice but to re-freeze it into frozen pork cutlet.

On the other hand, in the pork cutlet producing process using the pork cutting machine A of the present invention, slices can be sliced in a chilled state at about 0 ° C., so that the meat can be immediately added with oil without thawing and the meat is soft and has a good taste. Since it is possible to choose to make pork cutlet (chilled pork cutlet), there is an advantage that pork cutlet can be made quickly and efficiently on demand. Further, in the case of making frozen tonkatsu, conventionally, the step of completely freezing was required twice, but if the meat cutting machine A of the present invention is used, only one freezing is required, and the taste of the meat is improved accordingly. It is advantageous in terms.

Further, conventionally, in order to make the cut pieces of pork m cut into pieces having a predetermined size, shape and thickness in order to increase the commercial value, the step of shaping the pieces by pressing them in the state of chunk meat before cutting However, in the meat cutting machine A according to the present invention,
Since the shape and size can be shaped into a predetermined shape when passing through the guide block 2, there is also an advantage that a press is unnecessary. In other words, it is possible to slice the irregular-shaped meat block into a fixed shape and a fixed amount without requiring complicated and numerous steps.

[Other Embodiments] In the meat cutting machine A, in order to finish the cut surface by the cutter 4 into a more beautiful surface and to maintain the shape and thickness defined by the mold block 5 even after cutting, It cuts in the state of being cooled to 1 ° C below 0 ° C, but if it only cuts well,
It is also possible to cut at a temperature of around + 5 ° C.

For example, as shown in FIG. 5, the cylinder chamber 1S has an oval shape in a plan view, and a mold having a meat insertion hole 5A having an arc-shaped long hole in order to cut the pork piece m into a shape suitable for pork cutlet. Meat provided with a block 5 and a guide block 2 having an inlet shape of an ellipse and an outlet shape of which has an outlet hole 2A formed in the same circular arc long hole as the meat insertion hole 5A as shown in FIG. Cutting machine A may be used.

The shape setting mechanism K may have a structure in which a plurality of shutter plates are movably provided like a camera shutter so that the outlet shape can be arbitrarily changed without replacing the guide block 2. .

4B is a sectional view taken along the line aa of FIG. 4A, and FIG. 5B is a sectional view taken along the line bb of FIG. 5A. Alternatively, the cylinder 1 may be placed in a recumbent posture and the piston 3a may be moved laterally to form a horizontally placed meat cutting machine that discharges cut meat pieces m vertically and horizontally.
