Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a solid food product that can cut shavings of a constant thickness from solid foods such as dried bonito flakes and dried and solidified meat, and that can adjust the thickness as appropriate. This invention relates to a method for cutting food and drinks.

Conventionally, this type of cutting method includes one using a planer-like plate blade and one using a blade roller having a helical blade formed on the outer periphery of the roller.

In the former method, as shown in Fig. 1, a plate-shaped blade (planer blade) a is attached to a cutting table b, and the bonito flakes c are pressed against it for cutting.As shown in Fig. 2, a plate-shaped blade a is attached. A method of cutting the bonito flakes c by rotating the rotary plate d and pressing the bonito flakes c against the plate-shaped blade a using the spring e, as shown in Fig. 3, by feeding the bonito flakes c in the case f a fixed amount at a time by rotating the feed screw g. A method of cutting by pressing against a plate-shaped blade a, as shown in Fig. 4, a plane (plate-shaped blade) a is attached to a plane mount d whose front surface h is mortar-shaped, and a bonito flakes c are attached to this plate-shaped blade a. There are methods of cutting by pressing the material.

As for the latter method, as shown in Fig. 5, two blade rollers j with helical blades i formed on the outer periphery of the rollers are arranged in parallel, and while they are rotated, dried bonito flakes c are attached to the two blade rollers j by springs k. There is one that cuts by pressing.

However, among these methods, the first four methods using the plate-shaped blade a all have the following common drawbacks.

(b) During cutting, solid food and drink c gets bitten into the plate-shaped blade a, and the impact at that time can chip the solid food and drink, causing lumps of solid food and drink to get mixed into the scraped pieces. When placed in the mouth, it hits the teeth, giving a foreign body sensation and spoiling the taste.

(b) It is easy for shavings and powder to get clogged between the shaving table b or rotary plate d and the plate-shaped blade a, and if the blockage occurs, the protrusion of the plate-shaped blade changes, making it impossible to cut to a constant thickness, or during the rainy season. Or, in a hot and humid working environment, this can cause the proliferation of bacteria, which is unfavorable in terms of food hygiene.

(c) With a plate-shaped blade, the cutting resistance is large and the blade wears out severely, so the protrusion of the blade must be adjusted frequently or the blade must be changed, which requires stopping the cutting operation immediately. Because it has to be
There are various drawbacks such as poor work efficiency and productivity.

Furthermore, in the method shown in Fig. 2 among the methods shown in Figs. 1 to 4, the bonito flakes c are pressed by the spring e, so the spring e is different between before the bonito flakes are cut and after the bonito flakes are cut and thinned. There is also a drawback that the pressing force changes, causing variations in the pressing force, and as a result, the thickness of the cut piece tends to be non-uniform. Furthermore, since the bonito flakes are pressed by the spring e, they are constantly pressed against the rotary plate d and overheat, resulting in oxidation of the bonito flakes, loss of flavor, and poor color luster.

In the method shown in Figure 3, the bonito flakes c are not pressed by a spring, but are fed a fixed amount at a time by a feed screw g, so the above-mentioned drawbacks of the method shown in Figure 2 are somewhat alleviated, but the cutting tool is a plate-shaped blade. Therefore, if the feed amount of the bonito flakes is reduced so that it does not contact the rotating plate d but only the plate-shaped blade a, the bonito flakes become unstable and cannot be cut. Therefore, in order to cut the bonito flakes, it is necessary to press it not only against the plate-shaped blade a but also against the rotating plate d as shown in Fig. 3, and for this reason, the bonito flakes c
It is still inevitable that the color will overheat or the color will deteriorate. Moreover, if the bonito flakes are always pressed against the rotary plate d, the thickness of the cut pieces will be determined by the protrusion dimension of the plate-shaped blade a (the thickness will be the same as the protrusion dimension, and even if it is thicker or thinner, the thickness of the cut pieces will be determined by the protrusion dimension of the plate-shaped blade ) Even if you adjust the rotation speed of the rotary plate or the amount of bonito flakes fed, you cannot adjust the thickness of the scraped pieces. Therefore, in order to adjust the thickness of the scraped piece, it is necessary to stop the rotation of the rotary plate d and adjust the protrusion dimension of the plate-shaped blade a, which is a hassle. Moreover, in this case, the greater the number of plate-shaped blades attached to the rotary plate, and the longer the length of the plate-shaped blades, the longer the adjustment takes, resulting in a significant drop in work efficiency and productivity.

In addition, if the plate-shaped blade a is long, it is difficult to make it protrude uniformly over the entire length, and if there are many blades, and only one blade protrudes excessively, the solid food and drink will be pressed strongly by that blade. This results in insufficient pressure on the other blades, reducing cutting efficiency, and unavoidably applying excessive force to the extremely protruding blades, resulting in distortion of the disc and, as a result, uneven thickness of the cut joints.

Moreover, it takes a long period of skill to be able to adjust all the plate-shaped blades uniformly, and even for an expert, it takes about 3 to 5 minutes to adjust the blades on a sharpening machine with 16 blades. It takes a minute. Furthermore, even if you are an expert, the adjustment is done by feel, so there is considerable variation in the time of adjustment and depending on the sharpening machine, and if the person making the adjustment changes, there will be variations even on the same sharpening machine, and as a result, the thickness of the cut knots will vary. The length also varies.

In the case of Fig. 4, the front surface h of the plane mount (rotating body) d
Since the bonito flakes are mortar-shaped, the stability of the bonito flakes is improved compared to the case shown in FIG. 2, but since the blade used is a plate-shaped blade a, the disadvantages that arise from using it still remain. Moreover, the plane mount (rotary plate)
Since the front surface h of d is mortar-shaped, the center of the tip of the bonito flakes is guided to the mortar-shaped center (the part without the plate-like blade), and the center of the bonito flakes is cut. It also has the disadvantage that it remains unused.

Among the conventional methods, the method using a blade roller j formed with a helical blade as shown in FIG. 5 has the following drawbacks.

Since the bonito flakes c are pressed against the blade roller j by the spring k, the bonito flakes are constantly pressed against the blade roller regardless of whether or not they are cut by the blade roller, which adds more pressing force than necessary to the helical blade. . Therefore, the cutting resistance increases, the blade becomes more likely to wear, and the quality of the dried bonito flakes deteriorates, such as overheating and oxidation, loss of flavor, and poor color luster.

In addition, when the two blade rollers are rotated both outward as shown in Figure 5B, when they are both rotated inward as shown in Figure 5C, one is rotated outward as shown in Figure 5D,
In either case when rotating the other inward, if the pressing force of spring k is weak, the bonito flakes c will be pushed back by the rotational force of the two-blade roller j and will be difficult to cut. must be at least the same as or slightly stronger than the rotational force of the two blade rollers j. However, if you press it that strongly, unreasonable force will be applied to the blade roller j.
becomes difficult to rotate. If you intentionally rotate it, the bonito flakes may chip or break, and in some cases, the blade roller may even break.

In particular, in the case shown in Figure 5B, since the rotational forces of the double-edged rollers j are in opposite directions, the dried bonito flakes are likely to crack, chip, or tear, and the shavings, which have a substantially constant shape, thickness, etc. It's difficult to obtain. Furthermore, it is impossible to cut the material as thin as several microns. In addition, when two blade rollers j are used, they cannot be brought into contact with each other, so they must be separated, and if they are separated, the bonito flakes will not be cut by that much, and they will enter between the blade rollers and cause the rotation of the blade rollers. may stop.

In the case of Fig. 5 C, the two blade rollers j rotate inward, so if the double-edged rollers were placed close together, the cut pieces would get stuck between the blade rollers, causing the scraping. Fragments are no longer discharged outside. In order to solve this problem, it is necessary to separate the double-edged rollers a little, and if you do this, the bonito flakes c will remain uncut by that distance, and the remaining pieces will be drawn between the double-edged rollers and become clogged. If the rotation of the blade roller stops, or the blade becomes like a crusher that crushes the bonito flakes between the double-edged rollers, the bonito flakes will chip, crack, or crumble, resulting in shavings of a very constant thickness. I can't do that.

In the case of Fig. 5 D, one blade roller rotates inward and the other blade roller rotates outward, so that the blade roller on the left side rotates downward to the right from the center O of the cutting surface of the dried bonito c. Cutting force is applied, but the center part O
On the slightly right side R, a cutting force directed upward to the right is applied by the blade roller on the right side, so a cutting force in a completely opposite direction is applied to the central part O of the bonito flakes, causing the bonito flakes to chip or crack, resulting in a constant shape. It is difficult to obtain shavings. Also in this case, if the two blade rollers are not kept apart, the shavings cut by the left blade roller will not be discharged, so the double-edged rollers must be kept a certain distance apart. There is a drawback that the blade roller stops rotating due to the unsharpened bonito flakes clogging up.

The present invention does not have such various problems, and moreover, the thickness of the cut piece to be cut can be freely adjusted by adjusting the rotational speed of the rotary blade and/or the feed rate of the material to be cut. provides a cutting method capable of obtaining scraped pieces having a constant thickness, and this will be described in detail based on the embodiments shown in FIG. 6 and below.

A rotary knife 4 having a cutting edge 3 formed on the tip end surface 2 of the rod-shaped base material 1 is rotated in a fixed direction by itself, and the solid food A is transported by the transfer body 5 (FIGS. 8 and 9). The solid food A is transferred by a fixed amount according to the amount of rotation of the rotary knife 4 and pressed against the cutting blade 3 of the rotary knife 4 from the longitudinal direction, and the solid food A is supported by a steady rest support 6 and cut. It is something.

The shape of the cutting blade 3 may be selected as appropriate. For example, if the shape is made as shown in FIG. 6 so that the entire cutting blade 3 comes into contact with the tip surface B of the solid food A having a circular cross section, The front shape of the cutting piece 7 to be cut is the same as the locus of one revolution of the cutting blade 3, as shown in FIG. 7A. In this case, cutting piece 7 is 5/100
When cut to a thickness of less than mm, many wavy wrinkles 8 appear from the outer periphery toward the center, and the outer periphery curves slightly inward, so the basic side surface shape of the cut piece 7 becomes a conical shape as shown in Figure 7 (b). .

Moreover, what is shown in FIG. 7 is only the shape when the rotary blade 4 is rotated once; if the rotary blade 4 is rotated continuously, this shape will continue, and if the amount of transfer is smaller than the amount of cutting, the rotation will continue. Each time the blade 4 rotates once, a piece is cut into pieces.

Furthermore, the shape of the scraping piece 7 depends on the shape of the cutting edge 3 and the cutting edge 3.
By changing the cross-sectional shape, etc. of the solid food/drink A that comes into contact with the solid food/drink A, it becomes compatible with those shapes. For example, if the solid food A has a triangular cross-sectional shape and is cut by bringing the cutting blade 3 in the shape shown in FIG. It becomes a triangle.

Furthermore, if the solid food A is the conventional spindle-shaped dried bonito flakes, the shape is not uniform over the entire length, so even if the same rotary knife 4 is used, depending on the cutting location of the solid food A, there may be shavings. Although the size and shape of the shavings 7 are different, no matter which part of the solid food A the shavings 7 are cut from, it will correspond to the rotational shape of the part of the cutting blade 3 that is in contact with the solid food A. There is no change.

Next, as an example of a sharpening machine for carrying out the present invention, the one shown in FIGS. 8 to 12 can be considered.

This means that when the rotating shaft 10 is rotated by rotating the handle 9 in FIG. 8, the gears 11 ₁ , 11 ₂ , 11
₃ rotates to rotate the rotary shaft 12, and at the same time, a rotary cutter 4 such as an end mill attached to the rotary shaft 12 via a jig 13 rotates. As a result of this rotation, the cutting blade 3 formed at the tip of the rotary blade 4 cuts the tip surface B of the round bar-shaped solid food A with a diameter of about 2 to 3 centimeters that comes into contact with it, and the rotation of the rotary blade 4 causes the conveyor to 5 moves. The transfer body 5 includes a feed shaft 15 having a feed screw 14 formed on its outer periphery, and round bar-shaped guide rods 16 ₁ , 16 ₂ by rotation of the feed shaft 15 .
and a clamping jig 17 that is transferred to the rotary blade 4 side by a certain amount along the cutting edge.

The rotating shaft 10 is connected to the left side wall 21 of the housing 18 and the housing 18
Support part 22 protruding from the back wall 19 to the top of the drawing
The shaft 23 is attached to the left side wall 21, and the rotary shaft 12 is rotatably installed between the left side wall 21 and a support plate 24 protruding from the back wall 19 toward the top in the drawing. It is constructed so that

Further, a worm 25 is formed on the rotating shaft 10, and this worm 25 meshes with a worm gear 27 attached to a rotating shaft 26 vertically attached to the support portion 22. As shown in Fig. 10, a bevel gear 28 is attached, and this bevel gear 2
8 meshes with a bevel gear 29 attached to the tip of the feed shaft 15.

The feed shaft 15 is connected to the right side wall 30 and the back wall 1 of the housing 18.
It is rotatably installed between the support plate 31 and a support plate 31 protruding from 9 to the upper front side in the drawing. Guide rod 16
₁ and 16 ₂ are installed and fixed vertically in parallel between the right side wall 30 and the support plate 31. The support plate 31 has a through hole 32 through which the rotary cutter 4 projects.

As shown in FIGS. 11 and 12, the clamping jig 17 includes a main body 33 through which the guide rods 16 ₁ and 16 ₂ and the feed shaft 15 pass, and a main body 33 that overlaps with the main body 33 to hold the solid food A. The presser body 34 has an upper end 35 attached to the main body 33 with a bolt 37 with a spring 36 interposed, and a lower end 38 attached to the main body 33 with a bolt 40 with a spring 39 interposed.
3 so that when the knob 41 of the bolt 40 is turned, the lower part 38 of the presser body 34 opens and closes in the direction of the arrow X--X'. By this opening and closing, the solid food A inserted between the triangular receiving recesses 42 ₁ and 42 ₂ provided opposite to the main body 33 and the presser body 34 is clamped.
It is designed to be removable.

In addition, the clamping jig 17 has a movable piece 44 arranged in a storage part 43 recessed in the right side of the main body 33, and its lower end is attached with a pin 45, so that the movable piece 44 is attached to the pin 45.
5 as an axis in the direction of arrow YY'. Furthermore, a bolt 4 is inserted from the presser body 34 side into a screw hole opened at the upper end of the movable piece 44.
By screwing in the threaded portion 47 of No. 6 and rotating the knob 48 of this bolt 46, the movable piece 44 is attached to the pin 45.
It is designed to tilt and stand up in the Y-Y' direction using the fulcrum as a fulcrum. When the movable piece 44 stands up in the Y direction, the thread groove 49 formed therein meshes with the feed screw 14 on the outer periphery of the feed shaft 15, and in this state, when the handle 9 is turned to rotate the rotary cutter 4, the feed shaft 15 rotates. Accordingly, the clamping jig 17 is transferred to the rotary cutter 4 side. Conversely, when the movable piece 44 tilts in the Y' direction, the engagement between its thread groove 49 and the feed screw 14 is released, and even if the handle 9 is rotated, the clamping jig 17 will not be transferred, and the clamping jig 17 will not be moved by hand. It is designed so that it can be pulled back to the right.

To use this, turn the knob 41 to open the presser body 34, insert the solid food A between the receiving recesses 42 ₁ and 42 ₂ , and then turn the knob 41 in the opposite direction to open the presser body 34. Close it and clamp the solid food/beverage A.

Next, by turning the knob 48 and tilting the movable piece 44 toward the Y' side, the engagement between the screw groove 49 and the feed screw 14 of the feed shaft 15 is released, and in this state, the clamping jig 17 is guided manually. The solid food A is transferred along the rods 16 ₁ and 16 ₂ to the rotary cutter 4 side, and the tip of the solid food A is inserted into the steady rest hole 20 of the support 6 protruding from the back wall 19 toward the upper front in the drawing. Place it in contact with the tip of 4.

Then, by turning the rear knob 48 in the opposite direction to the previous direction to raise the movable piece 44 in the Y direction, the screw groove 49 and the feed shaft 15 are brought into engagement.

In this state, if the handle 9 is turned to rotate the rotary blade 4, the solid food A that is in contact with the blade 4 will be cut.

At this time, the worm gear 27 meshing with the worm 25 rotates, so the bevel gears 28 and 29 also rotate, and as a result, the feed shaft 15 also rotates, so the clamping jig 17 is automatically transferred to the rotary cutter 4 side. Ru.

The support device 6 is used to prevent the solid food A from vibrating or shaking laterally during cutting, and is shown in FIGS. 8 and 9.
In the illustrated example, a steady rest hole 20 into which the leading end of the solid food A can be inserted is formed in a plate protruding from the back wall 19 of the housing 18 toward the front in the drawing. It goes without saying that the support 6 may be of a type other than what is shown in the drawings, and may be appropriately selected depending on the purpose of preventing the solid food A from lateral shaking or vibration.

In the figure, 50 is a saucer that can be taken in and out of the housing 18. Further, the rotary cutter 4 may be automatically rotated by a motor or the like instead of being manually operated by the handle 9.

As described above, the present invention uses a rotary cutter 4 in which a cutting edge 3 is formed on the tip end surface 2 of a rod-shaped base material 1, so that the conventional plate-shaped blade (planer blade) a is not used. Various defects when cutting are eliminated. In addition, in addition to pressing the solid food A against the plate-like blade as in the case of using the plate-like blade a, the solid food A is also pressed against the rotating plate d, and the solid food A is pressed against the rotating plate d.
If it is not supported, it will not be cut. Therefore, the solid food A can be cut by being transferred so that it is pressed only against the cutting blade 3, without pressing it against the tip surface 2 of the rod-shaped base material 1, using the conveying body 5 whose feeding amount is freely adjustable. In this way, unlike when using the plate-shaped blade a, the solid food and drink A will not be pressed against the rotary plate or the shaving table and overheated.

In addition, in the present invention, the thickness of the scraped piece is not determined by the protrusion dimension of the plate-shaped blade as in the case of using the plate-shaped blade a, but the thickness of the scraped piece is not determined by the protrusion dimension of the plate-shaped blade, but is Since it is determined by the relationship S/R between the feed rate S (cm/min) of A and the rotation speed R (rpm) of rotary cutter A, the desired thickness of the scraped piece can be obtained very easily by adjusting these values. The thickness can be adjusted.

Furthermore, in the present invention, only one rotary cutter A is rotated in a fixed direction, so if the solid food A is chipped, cracked, or torn, as in the case of FIG. 5 where two blade rollers j are arranged side by side, It is possible to cut extremely smoothly without any scratches, and there is no drawback mentioned above when using two blade rollers side by side.

Moreover, what is rotated by itself is the rotary knife 4 itself, which has a cutting edge 3 formed on the tip surface 2 of the rod-shaped base material 1, and as shown in FIG. (Plate-shaped blade) Since it is not a device that rotates the object to which a is attached, the center of the solid food A may remain uncut, as in the case of Fig. 4, or the thickness of the scraped piece may be It has never been said that it is regulated by the protrusion size of the.

Furthermore, in the present invention, the solid food A is supported by the support 6 to prevent shaking, vibration, etc. of the solid food and drink A, making it possible to cut the solid food A even more smoothly. It becomes difficult to crack, chip, or tear, and it becomes easier to obtain shavings of a certain thickness.

In the rotary cutter 4 of the present invention, the cutting edge 3 is formed at the tip of the rod-shaped base material 1, so that the cutting joint cut by the cutter 4 having a conical tip as shown in FIG. 7 is shown in FIGS. , C becomes a conical shape, creating a new shape of the shavings that is completely different from the shape of previous shavings. Further, the shavings cut by the blade 4 having a planar tip become disk-shaped, and the shavings have a new shape that is different from the shape of conventional shavings.
