Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a snack food molding device, and in particular to a snack food molding device that can industrially advantageously mold snack foods having a beautiful appearance and shape, such as a three-dimensional ribbon-shaped boat shape. Regarding.

In recent years, snack foods, which are mainly made from grains such as rice, wheat, and corn, and starch, have become extremely popular as new foods that match the sensibilities of the times. In addition, under these current circumstances, snack foods with various appearances and shapes are required in order to satisfy not only convenience, economy, and nutrition, but also palatability.

By the way, snack foods with a unique appearance and shape made by folding or pressing dough are also known, such as ribbon-shaped snack foods.
The above-mentioned ribbon-shaped snack food is generally produced by rolling thin dough, cutting it into square or nearly square pieces of dough, folding the dough pieces in half, and crimping them approximately in the center. It can be made by hand. The ribbon-shaped snack food produced as described above has a beautiful appearance and shape, with the crimped portions of the dough pieces resembling ribbon knots. By the way, a device for forming ribbon-shaped snack foods is disclosed in Japanese Patent Publication No. 58-35063,
As proposed in US Pat. No. 3,504,640.

However, ribbon-shaped snack foods have not yet been commercialized. In order to improve these known devices, the present inventors have aimed to industrially advantageously produce ribbon-shaped or boat-shaped snack foods that have a three-dimensional effect and do not cause peeling of the crimped portion of the dough during molding. I pursued research as a purpose.

As a result of the research, the present inventors have developed the structure of the forming device as follows: 1. A device for supplying the strip-shaped dough; 2. The shape of each outer peripheral edge is arranged so as to cooperate with each other, and curves the strip-shaped dough along the longitudinal direction. 3. A crimping device; 4. A cutting device provided on the outer peripheral edge of the above-mentioned uneven roll and/or on the crimping device and capable of cutting the strip-shaped fabric into fabric pieces of a specific length. The apparatus shall consist of a device, which rotates the uneven rolls at the same speed in opposite directions so that the outer peripheral edges of each roll are engaged, and drives a crimping device to crimp the strip-shaped fabric at a predetermined portion; When a belt-shaped fabric is supplied, the belt-shaped fabric is pinched by the outer periphery of the roll, folded into a curved shape, crimped at a predetermined part, and cut into pieces of specific length to form a ribbon shape or a good shape. It has been found that snack foods can be formed into desired shapes such as boat shapes.

In addition, in the device proposed in the above-mentioned known document, the outer peripheral surface of the roll and the cutting blade in contact with the roll are flat, and the fabric after crimping is pressed flat and cut, so that the crimped part is cut when cutting. There was a high risk of the ribbon separating, and the resulting snack food lacked three-dimensionality because the hem of the ribbon was flat. However, by configuring the device of the present invention so that the cutting blade can be applied to the belt-shaped fabric in a state in which it is folded by the uneven roll, the crimped portion does not separate during cutting. At the same time, we learned that a ribbon-shaped snack food with a three-dimensional appearance, in which the outer periphery of the ribbon is curved, can be continuously molded.

The present invention has been made based on the above findings, and the gist thereof is: 1) a feeding device for feeding a strip-shaped fabric; 2) a device for curving the strip-shaped fabric along the longitudinal direction; 3) a crimping device for crimping the fabric strip, and 4) an outer surface of the textured rolls for cutting the fabric strip into pieces of specified length. a cutting device provided on the periphery and/or on the crimping device;
It is characterized by a snack food molding device consisting of:

Hereinafter, the molding apparatus of the present invention will be explained in detail based on the drawings. An example of the molding apparatus of the present invention is shown in FIGS. 3 to 5.

The molding device of the present invention comprises a feeding device for the strip-shaped dough 4, convex rolls 5 and concave rolls 6 for molding the strip-shaped dough 4 into a substantially ribbon-shaped snack food, a crimping device, and a cutting function.

The feeding device includes a convex roll 5 that holds the strip-shaped fabric 4.
This is for quantitatively supplying it with a constant tension in the longitudinal direction to the point where the concave roll 6 engages. In the illustrated example, the feeding device comprises a guide roll 33, a guide chute 7, a feed roll 8 and a guide plate 9.

The convex rolls 5 and the concave rolls 6 are for curving the strip-shaped fabric 4 along the longitudinal direction. In the illustrated example, the convex roll 5 and the concave roll 6 are fixed to two parallel rotating shafts 10 and 11 with a key 12,
They are set up to cooperate with each other.

As shown in detail in FIGS. 6a, 6b, and 6c, the outer circumferential surface of the convex roll 5 has, for example, an inverted V-shape or an inverted U-shaped convex protrusions 17 are arranged at predetermined intervals.

Further, on the outer circumferential surface of the concave roll 6, a seventh a
As shown in detail in FIGS. 7b and 7c, a concave protrusion 18 whose cross section in the direction parallel to the rotating shaft 11 of the concave roll 6 is, for example, V-shaped or U-shaped is provided around the entire circumference. , are arranged at the same intervals as the intervals between the convex protrusions 17, and engage with the convex protrusions 17 provided on the outer peripheral surface of the convex roll 5. The concave portion 18' of the concave projection 18 is provided with a groove 28 on its top inner surface, which has a width approximately equal to the width of the strip-shaped fabric 4 and into which the strip-shaped fabric 4 fits. It is desirable that the end surfaces of the convex protrusion 17 and the concave protrusion 18 in the circumferential direction are inclined. The convex protrusion 17 is provided with a cutting blade 19 that can come into contact with the circumferential recess 18' of the concave protrusion 18, if necessary.

The shape of the outer periphery of each of the convex roll 5 and the concave roll 6 is not limited to that shown in the drawings, and they engage in an uneven shape so as to curve the strip-shaped fabric 4 along the longitudinal direction. Any shape may be used as long as the belt-like fabric 4 is pressed between the portions where the peripheral edges engage, as will be described later.

The rotating shafts 10 and 11 are gears 2 that mesh with each other.
1 and 20, and the convex roll 5 and concave roll 6 are connected to the convex roll 5 and concave roll 6 from a prime mover (not shown) via these gears 20 and 21, and convex protrusions 17 and concave protrusions 18 provided on the outer peripheral surfaces of the respective convex rolls 5 and concave rolls 6 are provided. , rotate in opposite directions to each other at the same speed so that they engage each other. Even when the circumferences of the convex roll 5 and the concave roll 6 are different, the rotation axes of the convex roll 5 and the concave roll 6 may be set so that the circumferential speeds of the rolls are equal to each other. As shown in the figure, if the convex roll 5 and the concave roll 6 have the same peripheral edge, the specific cutting blade 19 provided on the convex protrusion 17 will constantly come into contact with the concave portion 18' of the specific concave protrusion 18. , cutting blade 1
9 conforms to the shape of the specific recess 18' and can prevent damage thereto as much as possible. Alternatively, the position of either or both of the textured rolls may be made adjustable to adjust the degree of engagement of the textured rolls and the degree of contact between the outer peripheral edge of the textured roll 6 and the cutting blade 19.

Next, the crimping device is for crimping the ribbon-like fabric 4 folded into a curved shape at the part of the ribbon that becomes the knot. A pair of opposed press rolls 15,1 arranged vertically parallel to the rotation axis
Consisting of 6. Press rolls 15, 16
is appropriately supported, and the rotation axis 1 of the rolls 5, 6 is
It is fixed to rotating shafts 26 and 27 provided on a plane connecting these rotating shafts at right angles to 0 and 11.
The rotating shafts 26 and 27 are provided with bevel gears 24 and 25 that mesh with bevel gears 22 and 23 fixed to the rotating shaft 10 on both sides of the convex roll 5, respectively, and the press rolls 15 and 16 are connected to the convex roll. 5 and the concave roll 6 at the same speed as the circumferential speed of the outer periphery thereof. Press rolls 15, 16
is equipped with press members 13 and 14 of the same type, and the press members 13 and 14 are arranged between the parts where two adjacent convex protrusions 17 of the convex roll 5 and two adjacent concave protrusions 18 of the concave roll 6 engage. The belt-shaped fabric 4 is sandwiched in the direction of the rotating shafts 10 and 11 and crimped.

Further, the shape of the crimping surfaces of the press members 13 and 14 may be flat or have opposing protrusions, or may have a comb-like shape, a corrugated shape, etc., so that the crimping portions that form ribbon knots may be partially crimped. It can be made into any shape that is possible. When the strip-shaped fabric 4 is partially crimped, the strip-shaped fabric 4 is crimped very firmly, and this portion has sufficient strength against bending and cracking, so that it can be later subjected to drying treatment such as frying or baking. In this case, the puffing in this area is uniform and good, resulting in a snack food with a very light texture.

Furthermore, when the crimping device as described above is provided with a function for cutting the strip-shaped fabric 4, for example, the positions of the press rolls 15 and 16 can be adjusted to adjust the thrust force of the press members 13 and 14, The press members 13 and 14 may be provided with cutting blades, or the shape of their pressing surfaces may be sharp.

The crimping device described above in the present invention is only an example, and any crimping device can be used as long as it is possible to crimp the strip-shaped fabric 4 between the portions where the outer peripheral edges of the convex roll 5 and the concave roll 6 engage in an uneven shape. may be used. Furthermore, the above-mentioned crimping device is not of the type in which the crimping device is provided around the entire circumference of the roll, unlike those proposed in known documents, and therefore the device is not complicated and does not take up much space.

Next, a case will be described in which a snack food is actually molded using the molding apparatus having the above-described structure. The explanation will be given using an example in which a ribbon-shaped snack food is formed.

First, the raw material for the snack food is formed into a strip-shaped dough 4 and fed to a molding device.

Grain and water are used as the main raw materials for the dough. Here, the grains that are the main raw materials for the dough include, for example, rice, wheat, corn, barley, oats, and rye. These grains can be used alone or in various combinations. In addition to the above grains and water, it is also possible to use starch, salt, sugar, oil, malt, etc. as raw materials for the dough.

After mixing the above raw materials, cooking is performed as necessary to obtain dough. Mixing of raw materials is carried out using various mixed liquids, such as a kneader, and cooking usually means heating for cooking, which includes, for example, a cooker with a steam jacket, an extruder, etc. is used. In addition, when processing raw materials using an extruder, it is also possible to mix and cook the raw materials at the same time.

In addition, as described above, the moisture content of the dough obtained after mixing and heating the raw materials is calculated based on the total amount of dough.
The content is preferably 22 to 45% (weight ratio) in order to smoothly perform subsequent sheet forming, cutting, and molding processes.

The fabric obtained as described above is rolled using, for example, a rolling roll and slit into a constant width using a slitter or the like to form the strip-shaped fabric 4.

When rolling the dough, during the subsequent shaping process,
In order for the fabric to be well formed into a ribbon shape without adhering to equipment, etc., and for efficient drying when drying is performed after forming, the thickness of the fabric should be, for example, 0.5~
It is preferable to set it to 2 mm. Regarding the slits in the fabric, as mentioned above, the concave roll 6 of the forming device
If grooves 28 are formed in the grooves 28, it is desirable to slit the fabric to the width of the grooves 28.

The strip-shaped dough 4 rolled, for example through rolling rolls and a slitter, as described above is safely and instantaneously introduced into the feed roll 8 by the guide chute 7. In this case, the belt-shaped fabric 4 is
It is preferable that the feed roll 8 is introduced at the same speed as the circumferential speed of the feed roll 8. The strip-shaped fabric 4 sent to the feed roll 8 via the guide roll 33 is
As a result, it is quantitatively supplied with constant tension in the longitudinal direction to the point where the convex roll 5 and the concave roll 6 engage. The feed roll 8 is driven, for example, via a gear (not shown) that meshes with a gear 20 for driving the concave roll 6. Further, the guide plate 9 guides the belt-shaped dough 4 to the feed roll 8.
This is to enable smooth transfer from the roller to the concave roll 6.

The belt-shaped dough 4 is transferred from the feed roll 8 to the convex roll 5
When feeding between the concave rolls 6 and 6, it is preferable to set the circumferential speed of the feed roll 8 to be slightly higher than the circumferential speeds of both of the rolls. In this case, the strip-shaped fabric 4 is not stretched during forming and cutting between both rolls, and the strip-shaped fabric 4
There are no problems such as shrinkage or deformation after cutting, or shortening of cut dimensions.

The feed roll 8 or guide plate 9 is
It is desirable that the position where the strip-shaped fabric 4 leaves this and is supplied to both rolls 5 and 6 be located slightly on the concave roll 6 side. As a result, the strip-shaped fabric 4 is reliably received in the groove 28 of the concave protrusion 18 provided on the concave roll 6, and even if the coefficient of friction between the feed roll 8 and the strip-shaped fabric 4 fluctuates somewhat, for example, The strip-shaped fabric 4 is quantitatively supplied to the point where the convex roll 5 and the concave roll 6 engage.

When the strip-shaped fabric 4 is fed between the convex roll 5 and the concave roll 6 that are rotating in opposite directions, the strip-shaped fabric 4 first passes through the convex protrusion 17- of the convex roll 5, as shown in FIG. 8a. Cutting blade 19 provided in a
By contacting the recess 18' formed in the recessed protrusion 18-a of the recessed roll 6, the starting end 2
It is cut off at 9. In this case, the strip-shaped fabric 4 is folded into two in a curved shape at the portion where the convex projection 17-a and the concave projection 18-a engage. Further, the starting end 29 of the cut strip-shaped fabric 4 becomes the outer peripheral edge corresponding to one hem of the ribbon to be molded, and includes the convex protrusion 17-a of the convex roll 5 and the concave protrusion 18-a of the concave roll 6. It is pressed down by the engaging part and molded into a curved shape.

Next, the convex roll 5 and the concave roll 6 are rotated a little more from the above-mentioned positions to reach the state shown in FIG. 8b. That is, the convex roll 5 and the concave roll 6 are arranged so that the convex protrusion 17-a and the concave protrusion 18-a in the front stage and the concave protrusion 17-b and the concave protrusion 18-b in the rear stage partially engage with each other. The belt-shaped fabric 4 is also moved downward along with the rotation of both rolls.

In the above state, the press members 13 and 14 provided on the press rolls 15 and 16 sandwich the strip-shaped fabric 4 in the direction of the rotating shafts 10 and 11 of the convex roll 5 and the concave roll 6, and thereby the strip-shaped fabric 4 is crimped. Press member 1 of press rolls 15 and 16
3 and 14 are arranged at a predetermined interval so that each time the convex protrusions 17 on the upper and lower stages of the convex roll 5 and the concave protrusions 18 on the upper and lower stages of the concave roll 6 partially engage with each other, they enter between these parts. The press rolls 15 and 16 rotate at the same speed as the outer peripheral edges of the convex roll 5 and the concave roll 6. Therefore, when the convex roll 5 and the concave roll 6 are in the state shown in FIG. 8b, the press members 13 and 14 always press the strip-shaped fabric 4.

Next, the convex roll 5 and the concave roll 6 are rotated a little more from the above-mentioned positions to reach the state shown in FIG. 8c. In this state, the convex protrusion 17- of the convex roll 5
The cutting blade 19 provided at b comes into contact with the recess 18' formed in the recessed protrusion 18-b of the recessed roll 6,
The strip-shaped fabric 4 is cut at its terminal end 30 to obtain a ribbon-shaped piece of fabric. In this case, the terminal end 30 of the cut strip-shaped fabric 4 becomes the outer peripheral edge corresponding to the other hem of the ribbon, and the convex protrusion 17 of the convex roll 5
-b and the engaging portion of the concave protrusion 18-b of the concave roll 6, and is pressed into a curved shape. Further, in the above case, the terminal end 3 of the strip-shaped fabric 4
0 is cut in a concavely curved state along the direction in which it is folded in half, so no burden is placed on the part crimped in the previous stage, and it is possible to prevent the crimped part from coming off as much as possible during cutting.

As described above, the strip-shaped fabric 4 is rolled onto the convex roll 5.
The press member 13 provided on the press rolls 15 and 16 is pressed by the engaging portion of the convex protrusion 17 of the concave roll 6 and the concave protrusion 18 of the concave roll 6.
14, it is continuously formed into a ribbon-shaped snack food with a three-dimensional effect.

In addition, in the above-mentioned molding apparatus, the press member 1
If the pressure bonding device is provided with a cutting function by adjusting the thrust force of 3 and 14, or by providing a cutting blade in these, a cloth-shaped snack food as shown in FIG. 9a can be formed. Furthermore, in the above-mentioned molding device, if the cutting blade 19 provided on the outer peripheral edge of the convex roll 5 is removed and only the crimping device has a cutting function, a boat-shaped snack food as shown in FIG. 9b can be produced. Molded.

Since the snack food after molding tends to adhere to the outer periphery of either the convex roll 5 or the concave roll 6, it is preferable to provide an appropriate removal means in the apparatus. This removal means includes, for example, an air rejector 31 for blowing air to remove the snack food adhered to the roll as shown in FIG. It is possible to use a means for blowing air onto the piece (both not shown), or to coat the outer periphery of the textured roll with, for example, Teflon or the like.

The apparatus described in detail above is merely an explanation of one embodiment of the present invention, and various modifications and applications can be made without departing from the gist of the present invention.

The ribbon-shaped snack food that has been cut and shaped as described above is usually subjected to a drying process to produce a snack food with the desired texture. Here, the drying treatment means heat drying such as sun drying, hot air drying, deep-frying, baking, puffing, etc., or any combination thereof.

In one example of drying a snack food, the shaped dough pieces are collected and predried by a suitable method, such as by passing through hot air, for example to a moisture content of about 5-18%. Next, the snack food is heat-treated in oil at, for example, 150-300°C for 5-60 seconds to puff it up and give it a light texture.

In addition, in the snack food molded by the above-mentioned molding apparatus of the present invention, the outer peripheral edge is curved in advance, which corresponds to the hem of the ribbon, so when drying it, the hem of the ribbon is There is less tendency to warp in the direction, and the finished snack food therefore has a very three-dimensional appearance.

The snack food after the drying process is seasoned by an appropriate method such as soaking in a seasoning liquid or spraying a seasoning liquid and drying. In addition, seafood, nuts, dried fruits, etc. can be embedded in the dough pieces before drying, or the dried ones can be coated with chiyocolate, caramel, etc. In the above cases, very beautiful and highly palatable snack foods can be made. can be obtained.

As described above, according to the forming apparatus of the present invention, the strip-shaped fabric is pinched by the irregularities on the outer peripheral edge of the roll, folded into a curved shape, crimped at a predetermined portion, and cut into fabric pieces of a specific length. The snack food is then molded into the desired shape.

Moreover, by making the cutting blade provided on the outer periphery of the roll into a specific shape, it is possible to cut the strip-shaped fabric in a folded state, and the crimped part does not separate from the crimped part when cutting after crimping. The snack food obtained at the same time has a curved part corresponding to the hem of the ribbon or hood, giving it a very three-dimensional appearance.
