Description

  The present invention relates to a frozen fruit cutting apparatus that finely cuts frozen fruit in a frozen state, such as strawberry, mango, and melon, with a fruit as a main target.

  Shaved ice is well known to many people through daily eating and drinking. Shaved ice is a cube-shaped ice block formed on a side of about 2 to 3 cm, or a block-shaped ice block formed on a side of about 15 cm. Made. Patent Document 1 discloses an example of such an ice machine.

  Patent Document 1 is an ice cutting / breaking ice machine having an ice cutting blade for breaking a cube-shaped ice block together with an ice cutting blade for cutting. In general, in ice smashers that cut cube-shaped ice blocks including Patent Document 1, a bottomed cylindrical rotor is provided at a constant speed by a driving force of a motor, and is formed at the bottom of the rotor. An ice cutting blade is attached to the opening. Although the rotor and ice cutting tool are detachable from the main body of the ice machine, the main body of the ice machine cuts and discharges the drive unit by a motor or the like and the ice block charged in the rotor. In addition, it is not possible to divide the parts into ice cutting parts, and the parts constituting the ice cutting parts cannot be individually disassembled.

  The cutting edge of the ice cutting blade is disposed in the cutting space in the rotor through the opening, and the cube-shaped ice lump charged in the cutting space is cut with the rotation of the rotor. The finely cut ice is collected at a position below the rotor and placed in a bowl as shaved ice.

  By the way, the present applicant made frozen strawberry (frozen strawberry) finely shaved like shaved ice, put it on a strawberry sauce, and put the frozen strawberry mousse on this finely chopped frozen strawberry. Products (hereinafter referred to as “Ichigo Kezuri Products”) (registered trademark “Ichigo Kezuri”).

Japanese Examined Patent Publication No. 7-109337

  However, when trying to make a fruit kuri product such as a strawberry kakeri product using an ice cutter as in Patent Document 1, there are the following problems.

(1) The problem of not being able to make fruit-paste products with high commercial value Fruits such as strawberries, mangoes, and melons contain sugar, and the sugar content varies depending on the type of fruit and is the same fruit. However, the size of sugar content varies depending on the variety and individual fruits. When such a fruit is frozen, the hardness of the frozen fruit varies depending on the sugar content. Generally, when the sugar content increases, the frozen fruit hardness decreases, whereas when the sugar content decreases, Hardness tends to increase.

  Since the sugar content of strawberries is relatively low, such as about 10%, the hardness of frozen strawberries becomes relatively large and frozen strawberries tend to be hard. Therefore, when providing strawberry kake products with a reduced thickness so that the mouth feels good to the mouth, the rotor is rotated at a higher rotational speed, and the frozen strawberry is shaved. If it is not difficult to melt, the value of the strawberry ketsuzuri product will decrease.

  On the other hand, in mango and melon, the sugar content is relatively high, such as more than 15%, so the hardness of frozen mango etc. is not as high as that of frozen strawberries, and frozen mango etc. is softer than frozen strawberries It is cured with. Therefore, compared to the case of frozen strawberries, if the rotation of the rotor is slowed and the frozen mangoes are not cut away, the cut frozen mangoes etc. will be easily melted in a shorter time, and it will Product value will be reduced.

  Therefore, in ice smashers that use ice as the object to be machined with the blade, the rotational speed of the rotor is constant, so fruit smash products such as strawberry ketch products, mango ketch products, melon ketch products, etc. When trying to make, it is not possible to select an appropriate rotor rotation speed corresponding to the hardness of various frozen fruits, and it is not possible to make a fruit kuri product with high commercial value.

(2) A problem that cannot be handled efficiently when cutting multiple types of frozen fruits In an ice machine, the drive part and the ice cutting part cannot be divided, and the various parts constituting the ice cutting part cannot be disassembled. Therefore, for example, after making a strawberry kuri product, if you make different types of frozen fruits with the same ice cutter, such as when making a mango kuri product, the cutting residue of a type of frozen fruit that has been shaved first, It remains in the ice-cutting part, and is mixed into the next fruit mash product using other types of frozen fruits. Therefore, storefronts selling fruit kuri products must be equipped with multiple ice breakers separately for each product, such as for strawberry ketch products, mango ketch products, melon ketch products, etc. In addition to the above restrictions, the equipment cost is also high.

  In addition, especially in the summer, fruit kuri products sold at one store may exceed one hundred hundred meals a day. For example, ice cream machines for mango kuri products are sold in large quantities. In some cases, you may want to make strawberry kegori products using the supplement. However, in such a case, in the ice machine, the drive part and the ice cutting part cannot be divided, and the ice cutting part cannot be disassembled into individual parts. It is difficult to clean the ice machine and the ice machine cannot be cleaned quickly.

  The present invention has been made to solve the above-mentioned problems, and in producing a fruit kuri product obtained by finely cutting frozen fruit, a frozen fruit that can efficiently produce a fruit kuri product having a high commercial value. An object of the present invention is to provide a cutting device for a machine.

  The cutting apparatus for frozen fruits according to one aspect of the present invention made to solve the above problems includes a cutting tool capable of cutting frozen fruits in a state where the fruits are frozen, and an internal space capable of accommodating the frozen fruits. A frozen fruit storage means surrounded by an enclosure, a stirring means rotatably mounted in the frozen fruit storage means, and stirring the stored frozen fruit in the internal space; and A cutting unit comprising driving means for generating power necessary for rotation and control means for controlling movement of the driving means, and comprising at least the blade, the frozen fruit storage means, and the stirring means, The structure is configured to be detachable and detachable, and one or more sets of the cutting parts are selectively connected or disconnected by a connecting part and a cutting driving part composed of the driving means and the control means. about The stirring means rotates in a state controlled by the control means according to the sugar content of the frozen fruit, and the frozen fruit is scraped by the cutting tool while being rotated by the stirring means. And

  According to this aspect, for example, using various frozen fruits having different sugar levels, such as frozen strawberry, frozen mango, and frozen melon, various fruit crushed products such as strawberry ketchup products, mango ketchup products, melon ketchup products, etc. Even when the frozen fruit cutting device of the present invention is used for making, the frozen fruit shaving obtained by shaving the frozen fruit can be efficiently generated in an optimal state according to each fruit kneading product. As a result, the added value of the fruit mash products such as the strawberry mash, the mango mash, and the melon mash is increased, and the store can provide the customer with the fruit mash having a high commercial value. In addition, since one cutting part and another cutting part are compatible with the same cutting drive part and can be attached and detached, the operator can use strawberry scrap products, mango scrap products, melon scrap products, etc. A plurality of different kinds of fruit kuri products can be made efficiently and easily by sharing one frozen fruit cutting apparatus of the present invention. Moreover, since the number which installs the cutting apparatus for frozen fruits of this invention can be suppressed, equipment cost can be reduced. Furthermore, since the cutting portion and the cutting drive portion are completely separated, the cutting portion can be easily cleaned after being cut.

  In the above aspect, the surrounding portion includes a tapered peripheral wall portion formed in an inverted conical cylinder shape that narrows downward, and the cutting tool is located at a position along the inner peripheral surface of the tapered peripheral wall portion. It is preferable that the cutting edge is provided.

  According to this aspect, the frozen fruit is thinned with an optimum thickness so that the mouth feels a good texture in the mouth because the frozen fruit is smoothly cut at an appropriate rake angle regardless of the type of the frozen fruit. The sharpened frozen fruit shaving can be easily generated. Moreover, the frozen fruit shaving shaved by the cutting edge of the blade is easily discharged from the frozen fruit storage means to the outside by the rotation of the stirring means. Therefore, in making a fruit kuri product, the yield of the frozen fruit shaving produced can be further increased based on the frozen fruit put into the internal space of the frozen fruit storage means.

  In the above aspect, the cutting tool is formed in a flat plate shape, and is disposed in a posture inclined within a range of a mounting angle of 40 to 60 ° with reference to a virtual plane that is in contact with the outer peripheral surface of the tapered peripheral wall portion. It is preferable.

  According to this aspect, when cutting frozen fruit, for example, the cutting edge formed with a cutting edge angle of about 20 to 30 ° comes into contact with the frozen fruit that rotates in the frozen fruit storage means at an appropriate rake angle. The frozen fruit can be cut smoothly. Therefore, frozen fruit shaving that has been thinned and thinned so that a mouthfeel having a good texture can be easily produced, and a fruit kuri product with high commercial value can be provided.

  In the above aspect, the blade includes a blade support having a mounting surface on which the blade is disposed and a position restricting portion that restricts a position of the blade disposed on the attachment surface, and the blade support includes the frozen fruit accommodation. The cutting tool is disposed in the surrounding part of the means, and the position restricting part moves the cutting tool to the side of the first direction in which the frozen fruit storage means approaches or separates in the internal space. And by adjusting by sliding in the first direction in a state where the movement in the second direction orthogonal to the first direction is respectively limited in the same plane, the cutting edge of the cutting tool is adjusted. It is preferably positioned.

  According to this aspect, even if the operator is not accustomed to the replacement work of the blade, the worker can easily set the blade to be attached at a desired position. In particular, even if the position where the cutting edge of the cutting tool is set in the internal space of the frozen fruit storage means varies depending on the type of fruit kuri products, such as strawberry ketch products, mango ketch products, melon ketch products, etc. Makes it possible to easily position and set the cutting tool at the optimum mounting position according to the fruit kuri product to be made.

  In said aspect, it is preferable that the hard coating process whose hardness is higher than the base material of the said cutting tool is given to the surface of the said cutting tool.

  According to this aspect, when generating a frozen fruit shaving obtained by finely cutting frozen fruit, the use of a cutting tool that has been subjected to a hard coating treatment on the cutting edge results in the progress of wear of the cutting edge compared to a cutting tool that has not been subjected to a hard coating treatment. Can be suppressed. Therefore, the tool life until sharpening the cutting edge in a cutting tool that has been subjected to a hard coating treatment is, for example, several to several tens of times longer than the tool life until sharpening the cutting edge in a cutting tool that has not been subjected to a hard coating treatment. The frequency of sharpening the cutting edge can be reduced. Moreover, since the frequency of replacing with a new blade is also greatly reduced, the running cost applied to the blade is reduced.

  According to the frozen fruit cutting apparatus according to the present invention, a fruit slicing product having a high commercial value can be efficiently produced in making a fruit slicing product obtained by finely cutting a frozen fruit (frozen fruit).

  First, the cutting part 2 will be specifically described. 6 is an enlarged perspective view showing only the hopper with a cutting tool attached from the frozen fruit cutting apparatus shown in FIG. 3, and FIG. 7 is an exploded perspective view of FIG. The hopper 40 is made of an acidic substance, an alkaline substance, stainless steel having a corrosion resistance against water, a resin material, or the like. As shown in FIGS. 6 and 7, the frozen fruit 90 (see FIGS. 21 and 22) is used. It has an internal space 41 that can be accommodated. The internal space 41 is formed so as to be surrounded by the surrounding part 42. The surrounding portion 42 includes a tapered peripheral wall portion 43 formed in an inverted conical cylinder shape that narrows downward, a cylindrical straight peripheral wall portion 44 connected to the upper end side of the tapered peripheral wall portion 43, and a lower end of the tapered peripheral wall portion 43. It comprises an annular hopper side connecting portion 48 connected at a position.

  A bracket mounting surface 46 for attaching the blade bracket 50 and an opening 45 are formed in the tapered peripheral wall portion 43. The opening 45 inserts the cutting edge 62 of the cutting tool 60 attached to the cutting tool bracket 50 into the internal space 41, and at the same time, inserts the frozen fruit shaving 91 (see FIG. 1) in which the frozen fruit 90 is finely cut by the cutting tool 60 into the internal space. It is provided for discharging from 41 through the discharge port cover 86 to the outside.

  Further, the hopper 40 has a cylindrical convex portion 49 having a diameter smaller than that of the hopper side connecting portion 48 at the hopper side connecting portion 48, and a hook 32 </ b> B forming a part of the fixture 32 is connected to the hopper side connecting portion 48.

It is a flat blade. The long hole 61 is a through hole for inserting a bolt when the blade 60 is fixed to the blade bracket 50 by screw fastening. In addition, in the cutting tool 60, the part through which the bolt 65 is inserted is a side perpendicular to the cutting edge 62 (FIG. 9) from the opposite side parallel to the cutting edge 62 (upper left and right side in FIG. 9) instead of the long hole 61. It may be a notch extending toward the middle (vertical side).

Next, the cutting tools 60 and 60A will be described with reference to FIGS.
Example 1
The cutting tool 60 is a stainless steel cutting tool in which the surface 60 a is not subjected to a process for suppressing wear of the cutting edge 62. The cutting edge 62 is formed with strength that can cut the frozen fruit 90.

(Example 2)
FIG. 10 is a view showing a cutting tool having a hard coating layer on the surface thereof, as seen from a cross-section viewed from the position corresponding to the arrow BB in FIG. 9. As shown in FIG. 10, the cutting tool 60A is a cutting tool in which a hard coating layer 68 having a hardness higher than that of the base material is laminated on a surface 60a of a stainless steel cutting tool 60 as a base material. The hard coating layer 68 includes, for example, a single layer structure having only a surface layer laminated in close contact with the surface 60a, an intermediate layer functioning as a binder that enhances adhesion at the interface with the surface 60a, and a surface layer on the intermediate layer. A two-layer (multi-layer) structure is formed.

  When the hard coating layer 68 has a single layer structure, examples of the surface layer include a TiN vapor deposition layer having a thickness of about 4 to 6 μm. When the hard coating layer 68 has a two-layer structure, examples of the intermediate layer include a TiN vapor deposition layer having a film thickness of about 1.5 to 3.0 μm. Regardless of whether the hard coating layer 68 has a single-layer structure or a two-layer structure, the TiN vapor deposition layer has, for example, characteristics such as a surface hardness of Vickers hardness HV 1700-2200, an oxidation temperature of 600 ° C.

  As the surface layer of the hard coating layer 68 having a two-layer structure, for example, a TiAlN vapor-deposited layer, a TiCrAlN vapor-deposited layer, a TiCrAlSi vapor-deposited layer, diamond-like carbon (DLC) having a surface hardness of about Vickers hardness HV 1500 to 7000 Examples thereof include a vapor deposition layer having a hardness higher than that of an intermediate layer such as a film or a TiN vapor deposition layer. When this surface layer is a TiCrAlN vapor deposition layer, as an example, the TiCrAlN vapor deposition layer has characteristics such as a surface hardness of Vickers hardness HV2300 to 2900, an oxidation temperature of 800 ° C., and the like. The TiCrAlSi vapor-deposited layer has, for example, characteristics such as a surface hardness of Vickers hardness HV 2800 to 3600 and an oxidation temperature of 1100 ° C. The surface layer laminated on the intermediate layer is formed to a thickness of about 3.5 to 5.0 μm, and the total thickness of the hard coating layer 68 including the intermediate layer and the surface layer is about 4 to 6 μm.

  A method of treating the hard coating layer 68 will be briefly described by exemplifying the hard coating layer 68 formed of a two-layer structure of a TiN vapor deposition layer and a TiCrAlN vapor deposition layer. For the formation of the hard coating layer 68, a batch type vacuum deposition furnace in which an alloy (target) used as a material of the coating layer is deposited on the cutting tool 60 under vacuum by an arc ion plating (AIP) method. Is used. The batch type vacuum vapor deposition furnace has a structure in which targets can be arranged at a plurality of locations in the furnace, and a target made of TiN alloy as a material for the TiN vapor deposition layer and a target made of TiCrAlSi alloy as the material for the TiCrAlSi vapor deposition layer Are arranged at predetermined positions.

  On the other hand, before the vapor deposition, the cutting tool 60 is washed with high accuracy, the portions that do not require vapor deposition are masked as required, the cutting tool 60 is placed in a furnace under vacuum, and a target made of TiN alloy is first arced. Heating is evaporated, ionized, and gasified by electric discharge, and a TiN vapor deposition layer is vapor deposited on the surface 60 a of the blade 60. After vapor deposition of the TiN vapor deposition layer, a target made of TiCrAlSi alloy, which is a material of the TiCrAlSi vapor deposition layer, is heated and evaporated by arc discharge, ionized and gasified, and the TiCrAlSi vapor deposition layer is vapor deposited on the TiN vapor deposition layer.

  Next, the blade bracket 50 will be described. 11 is an enlarged perspective view showing the blade bracket shown in FIG. 7, and FIG. 12 shows a cross-sectional view taken along the line CC in FIG. FIG. 13 is a plan view showing the mounting surface viewed from the direction of arrow D in FIG.

  As shown in FIGS. 11 and 12, the blade bracket 50 has a base 51 formed in a shape in which a substantially triangular prism and a substantially quadrangular prism are joined, and a hopper mounting surface 52 and a blade mounting surface on the base 51. 53 (corresponding to the mounting surface of the present invention). The blade attachment surface 53 is relative to the hopper attachment surface 52 so that the first imaginary line L1 parallel to the hopper attachment surface 52 and the second imaginary line L2 parallel to the blade attachment surface 53 intersect at the attachment angle θ. Leaning on.

  This will be specifically described. FIG. 14 is an explanatory view schematically showing a mounting position relationship between the hopper and the cutting tool. As shown in FIG. 14, the hopper mounting surface 52 (second imaginary line L2) has a mounting angle θ based on a virtual plane M (first imaginary line L1) in contact with the outer peripheral surface 43a of the tapered peripheral wall 43 of the hopper 40. It is arranged in a positional relationship tilted to. The cutting tools 60, 60 </ b> A are disposed on the hopper mounting surface 52 and attached to the cutting tool bracket 50.

  This attachment angle θ is preferably in the range of 40 to 60 °, and is 50 ° in this embodiment. The reason for this is that the cutting edge angle of the cutting tools 60, 60A is 20 to 30 °, so that the cutting edge 62 disposed in the internal space 41 rotates in the hopper 40 when the frozen fruit 90 is cut, as will be described later. This is because the frozen fruit 90 can be cut into contact with the frozen fruit 90 at an appropriate rake angle, and the thin frozen fruit shaving 91 can be easily cut smoothly.

  The blade bracket 50 abuts the hopper mounting surface 52 against the bracket mounting surface 46 of the hopper 40, and a bolt 57 inserted into the stepped through hole 55 is inserted into the female screw 47 in the bracket mounting surface 46 as shown in FIG. 7. Are attached to the tapered peripheral wall 43 (enclosure 42) of the hopper 40 in a detachable manner.

  The blade attachment surface 53 is a plane on which the blades 60 and 60A are in contact with each other, and the blades 60 and 60A have bolts 65 inserted through the long holes 61 in the blade attachment surface 53 as shown in FIG. By being screwed to the female screw 56, the blade bracket 50 is detachably attached. The blade attachment surface 53 is provided with a position restricting portion 54, and the position restricting portion 54 restricts the positions of the blade tools 60 and 60 </ b> A disposed on the blade attachment surface 53.

  The position restricting portion 54 is formed so as to protrude higher than on the blade attachment surface 53. As shown in FIGS. 11 and 13, the position restricting portion 54 is a first position along one side (the upper side in the left-right direction in FIG. 13) of the long side of the blade attachment surface 53 formed in a substantially rectangular shape. It consists of a restricting portion 54A and a second position restricting portion 54B along one side of the short side (the right side in the vertical direction in FIG. 13).

  As shown in FIG. 6, the first position restricting portion 54 </ b> A limits the movement of the cutting tools 60 and 60 </ b> A toward the separation side S <b> 1 in the first direction S that approaches or separates in the internal space 41 of the hopper 40. The second position restricting portion 54B limits the movement of the cutting tools 60 and 60A in the second direction W orthogonal to the first direction S in the same plane.

  This will be specifically described. FIG. 15 is a cross-sectional view taken along line AA in FIG. FIG. 16 is a diagram illustrating a state of the cutting tool viewed from the inside of the hopper. When attaching the cutting tools 60, 60 </ b> A to the cutting tool bracket 50, the operator restricts the movement of the second direction W to the restricting side W <b> 1 by bringing the one side end face 64 into contact with the second position restricting portion 54 </ b> B. The blades 60 and 60A are disposed on the blade attachment surface 53 with the rear end surface 63 in contact with the first position restricting portion 54A. Thereby, the cutting tools 60 and 60A are positioned with respect to the second direction W. When the operator holds the cutting tools 60, 60A in this state, the bolt 65 is inserted into the long hole 61, and lightly fastened to the female screw 56 and temporarily fixed, as shown by a two-dot chain line in FIG. The cutting edge 62 of the cutting tool 60, 60 </ b> A is set at a position slightly outside the inner diameter 43 b of the tapered peripheral wall 43.

  Then, as shown in FIG. 6, the operator maintains the state in which the one end face 64 of the cutting tools 60, 60A is in contact with the second position restricting portion 54B so as not to be displaced to the counter-regulating side W2. As shown in FIG. 15, the cutting tools 60, 60 </ b> A are slid to the proximity side S <b> 2 in the first direction S. At this time, since the cutting tools 60 and 60A can slide by a distance that moves relative to the bolt 65 inserted through the long hole 61, the operator can move to a desired position in the internal space 41 (indicated by a solid line in FIG. 15). The movement of the cutting tools 60, 60A is finely adjusted with respect to the first direction S so that the cutting edge 62 can be arranged at the position shown.

  Thus, as shown in FIGS. 15 and 16, the cutting tools 60, 60 </ b> A have the cutting edge 62 disposed at a position along the inner peripheral surface 43 b of the tapered peripheral wall 43, and the bolt 65 and the female screw 56 are tightened and fixed. By doing so, it is set to a position suitable for obtaining the frozen fruit shaving 91 in the optimum state.

  Next, the stirring rotor 70 will be described. FIG. 17 is a perspective view showing a stirring rotor of the frozen fruit cutting apparatus shown in FIG. 1. 18 is a plan view showing the stirring rotor shown in FIG. 17 from above, and FIG. 19 shows a plan view showing the stirring rotor shown in FIG. 17 from below.

  The stirring rotor 70 is a member that is rotatably attached to the internal space 41 of the hopper 40 and that stirs the frozen fruit 90 accommodated in the internal space 41. The stirring rotor 70 is made of an acidic substance, an alkaline substance, a metal material having corrosion resistance against water, or a resin material. The stirring rotor 70 is formed by connecting a flange 76 formed in an annular shape and a boss 71 provided on the axis of the flange 76 by three blades 75 arranged at equal intervals of 120 °. A positioning hole 77 is formed in the flange 76, and the intermediate mounting member 81 is mounted by inserting the convex portion of the lower flange 82 (see FIG. 3) into the positioning hole 77 of the flange 76.

  When the agitation rotor 70 is attached to the hopper 40, the blades 75 are twisted between the flange 76 and the boss 71 while expanding outwardly so as to follow the inner peripheral surface 43b of the tapered peripheral wall 43 of the hopper 40. It is formed in the form it has. The boss 71 has a through hole 74 at the center thereof, and a support portion 73 that closes the periphery of the through hole 74 can be fitted on the upper side, and the anti-rotation member 17 that is a hexagon nut can be fitted on the lower side. Each has a fitting portion 72.

  Next, the cutting drive part 3 is demonstrated using FIG.3, FIG.5 and FIG.20. FIG. 20 is a diagram illustrating a state in which the cutting drive unit and the cutting unit are coupled to each other in the frozen fruit cutting apparatus illustrated in FIG. 1. Is illustrated. The motor 12 generates power necessary for the rotation of the stirring rotor 70. The control unit 10 is electrically connected to the switch 11 and the motor 12.

The control unit 10 performs control for turning on / off the operation of the motor 12 by the switch 11 and also performs inverter control for changing the rotation of the output shaft 13 of the motor 12 to an arbitrary rotation number. In the control unit 10, the rotation speed N of the stirring rotor 70 can be arbitrarily set. For example, the optimal rotation speed N that is different for each type of the frozen fruit 90 such as frozen strawberry, frozen mango, and frozen melon can be freely set. Can be set and stored. Even the same fruits, differences and varieties, depending fruits one by one, because of the width to the size of the sugar content, the rotational speed N of the stirring rotor 70 to set the center value the rotational speed N ₀ as a reference For example, it is preferably set based on a rotation speed band having a width of an allowable rotation range such as ± 10%.

  The control unit 10, the switch 11, and the motor 12 are disposed on the gantry 31. The entire gantry 31 is covered with a main body cover 84, and a front cover 85 that prevents the frozen fruit shaving 91 from scattering is provided at the lower periphery of the discharge port cover 86. The output shaft 13 of the motor 12 is inserted upward through the top plate of the gantry 31 and is connected to the transmission shaft 14 via the coupler 16. Thereby, the rotational force of the motor 12 is transmitted to the transmission shaft 14 having the male screw portion 15 at the tip. An anti-rotation member 17, which is a hexagonal nut, is attached to the male screw portion 15 by screwing, and an upper end side of the male screw portion 15 inserted through the anti-rotation member 17 is screwed to the fastening nut 35.

  The support member 21 is attached to the top plate of the gantry 31 with its bottom raised. The support member 21 includes a shaft holding portion 22 formed in a cylindrical shape having substantially the same diameter as the hopper side connecting portion 48 of the hopper 40, and a disk-like connection portion 23 having a diameter larger than that of the shaft holding portion 22. Yes. The transmission shaft 14 is liquid-tightly held on the shaft holding portion 22 of the support member 21 via two bearings 33 by a seal member (not shown). As described above, the fitting groove 24 is recessed in the connecting portion 23 so as to be able to fit into the convex portion 49 of the hopper 40, and the O-ring groove 25 is recessed in the bottom of the fitting groove 24. Yes.

  Further, the remaining part of the fixture 32 (retaining ring 32A, lever 32C) excluding the hook 32B is provided at two locations on the outer periphery of the connection part 23, and provided at the hook 32B and the hopper side connecting part 48 of the hopper 40. The retaining ring 32A can be freely moored or released by operating the lever 32C. That is, the hopper side connecting portion 48 of the hopper 40 and the connecting portion 23 of the support member 21 are the connecting portion 4 of the frozen fruit cutting apparatus 1.

  When connecting the cutting drive part 3 and the cutting parts 2 and 2A with the connecting part 4, as shown in FIG. 20, after the O-ring 34 is interposed in the O-ring groove 25, the convex part of the hopper 40 is provided. 49 is fitted into the fitting groove 24 of the support member 21. Next, when the retaining ring 32A of the fixing tool 32 is moored to the hook 32B, the hopper side connecting portion 48 of the hopper 40 and the connecting portion 23 of the support member 21 are fixed.

  Next, the operator inserts the through hole 74 of the boss 71 of the stirring rotor 70 into the male screw portion 15 of the transmission shaft 14 and fits the fitting portion 72 of the boss 71 into the anti-rotation member 17 in the hopper 40. The support member 73 of the boss 71 is supported by the rotation preventing member 17. At this time, if there is a possibility that the stirring rotor 70 may come into contact with the hopper 40, the rotation preventing member 17 is rotated, the position of the rotation preventing member 17 screwed with the male screw portion 15 is changed, and the height of the stirring rotor 70 is increased. Make adjustments.

  Next, the worker fastens the fastening nut 35 to the distal end side of the male screw portion 15 that has passed through the through hole 74 of the boss 71, whereby the stirring rotor 70 is sandwiched between the anti-rotation member 17 and the fastening nut 35. Fixed. Next, the operator inserts the convex portion of the lower flange 82 into the positioning hole 77 of the flange 76, and places the intermediate mounting member 81 on the stirring rotor 70 so that the frozen fruit 90 that has been introduced gathers in the center of the bottom of the hopper 40. The outer cylinder member 83 is placed on the outer peripheral edge of the flange 76. Thus, the connection between the cutting drive unit 3 and the cutting units 2 and 2A is completed.

  Next, the operation of the frozen fruit cutting apparatus 1 will be described. In the frozen fruit cutting apparatus 1, the peripheral speed V (m / sec) on the outer peripheral side of the blade 75 of the stirring rotor 70 varies depending on the type of the frozen fruit 90 (for example, frozen strawberry, frozen mango, frozen melon, etc.). The operator selects in advance an optimum rotation speed N (rpm) of the stirring rotor 70 corresponding to the type of the frozen fruit 90 to be cut, and sets it in the control unit 10.

  Specifically, for example, in the case of a frozen strawberry that has been frozen with a sugar content of about 10%, the operator must ensure that the peripheral speed of the blades 75 of the stirring rotor 70 is V1 (m / sec) (0 <V1). Then, the rotational speed N1 (rpm) (0 <N1) of the stirring rotor 70 is set in the control unit 10. On the other hand, in the case of a frozen mango obtained by freezing mango having a sugar content of more than 15%, the operator can use the stirring rotor 70 so that the peripheral speed of the blades 75 of the stirring rotor 70 becomes V2 (m / sec) (V2 <V1). The rotation speed N2 (rpm) (0 <N2 <N1) is set in the control unit 10. That is, the stirring rotor 70 rotates in a state controlled by the control unit 10 according to the sugar content of the frozen fruit 90.

  FIG. 21 is a schematic view showing a state in which frozen fruits are cut by the frozen fruit cutting apparatus shown in FIG. 1, and FIG. 22 shows a cross-sectional view taken along the line EE in FIG. When the operator puts the frozen fruit 90 into the internal space 41 of the hopper 40, the frozen fruit 90 gathers in the vicinity of the boss 71 of the stirring rotor 70, and when the stirring rotor 70 rotates, as shown in FIGS. Centrifugal force F acts on the frozen fruit 90. The centrifugal force F is a force obtained by synthesizing the first force component F1 along the inner peripheral surface 43b of the tapered peripheral wall portion 43 and the second force component F2 perpendicular to the inner peripheral surface 43b. Therefore, the frozen fruit 90 receives the action of the second force component F2 and receives the action of the first force component F1 along the inner peripheral surface 43b, and from above the boss 71 to above the tapered peripheral wall 43. Move towards.

  Thereby, the frozen fruit 90 thrown into the internal space 41 becomes easy to approach the blade edge | tip 62 of the blade tools 60 and 60A arrange | positioned at the taper surrounding wall part 43. FIG. Then, the frozen fruit shaving 91 having a reduced thickness is generated so that the cutting edge 62 can smoothly scrape the frozen fruit 90 that rotates in the internal space 41 at an appropriate rake angle, and provides a mouthfeel with a good texture in the mouth. Is done. The frozen fruit shaving 91 is sent into the discharge port cover 86 through the opening 45, and is discharged into a container prepared in advance below the discharge port cover 86 as shown in FIG. Thus, the frozen fruit 90 is scraped by the cutting tool 60 while being rotated by the stirring rotor 70.

  Actions and effects of the frozen fruit cutting device 1 according to the embodiment will be described. The cutting apparatus 1 for frozen fruits is formed by surrounding the surrounding portion 42 with a cutting tool 60, 60A that can cut the frozen fruit 90 in a state where the fruit is frozen, and an internal space 41 that can store the frozen fruit. The hopper 40, the agitation rotor 70 that is rotatably mounted in the hopper 40 and agitates the stored frozen fruit 90 in the internal space 41, the motor 12 that generates power necessary for the rotation of the agitation rotor 70, and the motor And a control unit 10 for controlling 12 movements.

  The cutting parts 2, 2A including at least the cutting tools 60, 60A, the hopper 40, the stirring rotor 70, and the like are configured to be detachable and detachable, and each of the one or more sets of cutting parts 2, 2A is formed. Optionally, the cutting drive unit 3 including the motor 12 and the control unit 10 and the like are connected or disconnected by the connecting unit 4, and the stirring rotor 70 is controlled by the control unit 10 according to the sugar content of the frozen fruit 90. The frozen fruit 90 is rotated in a controlled state, and the frozen fruit 90 is shaved by the cutting tools 60 and 60 </ b> A while being rotated by the stirring rotor 70.

  According to this aspect, using various frozen fruits 90 such as frozen strawberries, frozen mangos, frozen melons and the like with different sugar levels, strawberry ketchup products, mango ketchup products, melon ketchup products, etc. Even when the same frozen fruit cutting device 1 is used, the frozen fruit shavings 91 corresponding to each fruit kuri product can be efficiently generated in an optimal state. As a result, the added value of the fruit mash products such as the strawberry mash, the mango mash, and the melon mash is increased, and the store can provide the customer with the fruit mash having a high commercial value. In addition, since one cutting unit 2 and the other cutting unit 2A can be attached to and detached from the same cutting drive unit 3, an operator can use strawberry scrap products, mango scrap products, melon scrap products, etc. As described above, it is possible to efficiently and easily make a plurality of different types of fruit mash products by sharing one frozen fruit cutting device 1. Moreover, since the number which installs the cutting apparatus 1 for frozen fruits can be suppressed, installation cost can be reduced. Furthermore, since the cutting parts 2 and 2A and the cutting drive part 3 are completely separated, the cutting part 2 can be easily cleaned after being cut.

  Therefore, according to the frozen fruit cutting apparatus 1 according to the present embodiment, it is possible to efficiently produce a fruit slicing product having a high commercial value in making a fruit slicing product obtained by finely shaving the frozen fruit. Has an effect.

The cutting edge 62 of the said cutting tools 60 and 60A is arrange | positioned and provided in the position along 43b, It is characterized by the above-mentioned.

  Due to this feature, the frozen fruit 90 is smoothly cut at an appropriate rake angle regardless of the type of the frozen fruit 90, so that the frozen fruit 90 has an optimum thickness so that a mouthfeel can be given to the mouth. A thinly cut frozen fruit shaving 91 can be easily generated. Further, the frozen fruit shaving 91 shaved with the cutting edge 62 of the cutting tool 60, 60 </ b> A is easily discharged from the opening 45 of the hopper 40 to the discharge port cover 86 by the rotation of the stirring rotor 70. For this reason, in producing a fruit kuri product, the yield of the frozen fruit shaving 91 that is generated based on the frozen fruit 90 put into the internal space 41 of the hopper 40 can be made higher.

  In the frozen fruit cutting apparatus 1, the cutting tools 60, 60 </ b> A are formed in a flat plate shape, and the mounting angle is within a range of 40 to 60 ° with reference to the virtual plane M that contacts the outer peripheral surface 43 a of the tapered peripheral wall 43. It is characterized by being arranged in a posture inclined to

  Due to this feature, when cutting the frozen fruit 90, the cutting edge 62 having a blade edge angle of 20 to 30 ° is cut into contact with the frozen fruit 90 at an appropriate rake angle with respect to the frozen fruit 90 rotating in the hopper 40. The thin frozen fruit shaving 91 can be shaved smoothly. Therefore, the frozen fruit shaving 91 having a reduced thickness can be easily generated so that a mouthfeel with a good texture can be produced in the mouth, and a fruit kuri product having a high commercial value can be provided.

  In the frozen fruit cutting apparatus 1, the blade bracket 50 having the blade attachment surface 53 on which the blades 60, 60 </ b> A are disposed, and the position restricting portion 54 that restricts the positions of the blades 60, 60 </ b> A disposed on the blade attachment surface 53. The blade bracket 50 is disposed on the tapered peripheral wall portion 43 of the hopper 40, and the cutting tool 60, 60 </ b> A approaches or separates in the internal space 41 of the hopper 40 by the position restricting portion 54 in the first direction S. Among them, the movement to the separation side S1 and the movement to the second direction W orthogonal to the first direction S in the same plane are respectively limited and slid and adjusted in the first direction S. The blade edge 62 of the blade tool 60, 60A is positioned.

  With this feature, even if the operator is not familiar with the replacement work of the blade tools 60, 60A, the worker can easily set the blade tools 60, 60A attached to the blade bracket 50 at a desired position. . In particular, even if the position where the cutting edge 62 of the cutting tool 60, 60A is set in the internal space 41 of the hopper 40 varies depending on the type of fruit kuri products, such as strawberry kuri products, mango kuri products, melon kuri products, etc. The operator can easily position and set the cutting tools 60 and 60A at the optimum mounting position according to the fruit kuri product to be made.

  The frozen fruit cutting apparatus 1 is characterized in that a hard coating layer 68 having a higher hardness than the base material of the cutting tool 60A is formed on the surface 60a of the cutting tool 60A.

  Due to this feature, when generating the frozen fruit shaving 91 obtained by finely cutting the frozen fruit 90, the cutting edge 60 </ b> A in which the hard coating layer 68 is applied to the cutting edge 62 is used in comparison with the cutting tool 60 that is not provided with the hard coating layer 68. The wear of 62 is extremely suppressed. Therefore, when the frozen tool 90 is cut using the cutting tool 60 and the cutting tool 60A under the same conditions, the tool life until the cutting edge 62 of the cutting tool 60A is sharpened is, for example, sharpened the cutting edge 62 of the cutting tool 60. Compared to the tool life up to this time, it is greatly extended to several to several tens of times, and the frequency of sharpening the cutting edge 62 can be reduced. In addition, since the frequency of replacement with a new cutting tool 60A is greatly reduced, the running cost applied to the cutting tool 60A is reduced.
