JP4290101B2 - Die cutting method for rice crackers and dough - Google Patents

Description

  The present invention relates to a rice cracker having a unique shape having a plate shape and a hole in the inner part thereof, and a method for die cutting thereof.

  In general manufacturing processes such as rice crackers, a dumpling dough formed with rice flour (generally, rice is used, but some or all of it may be used) is rolled (rolled). Process) A dough sheet is formed, a die is cut from the dough sheet into a desired shape (die cutting process), the die cut dough is dried (drying process), and then baking such as predetermined baking and frying is performed. The surplus dough sheet that has been die-cut is returned to the squeezing step. (Patent Documents 1 and 2).

  In particular, in die cutting, when a cut is made in a dough sheet with a die-cutting roll provided with a punching-shaped frame-like protruding blade, the cut and cut dough portion is directly sandwiched between the frame-like protruding blades. A means for applying moisture for separation on the surface of the cutting roll is known so that the dough does not adhere to the die cutting cutting roll (Patent Document 1).

  In addition, rice crackers such as rice crackers are usually in the shape of a disc or an ellipse, and have a plate shape that is a normal shape and a specific shape (circular, star-shaped, heart-shaped) with a corresponding size penetrating the front and back. There is no known rice cracker.

  As a plate-shaped rice cracker with holes penetrating the front and back, as disclosed in Patent Document 3 (Japanese Utility Model Publication No. 3-12881), a small protrusion roller is used in the extending process, and a large number of small holes A dough sheet is formed, and a rice cracker dough is produced from the dough sheet by die cutting, and disclosed in Patent Document 4 (Japanese Patent Laid-Open No. 52-61267). As shown, the dough sheet was formed by using a longitudinal groove roller and a transverse groove roller in the extending process, forming a dough sheet in which the protrusion intersection part is a through hole, and performing die cutting of the rice cracker shape from this dough sheet Things are known.

  In these rice crackers, the outer shape is restricted by the shape of the through-holes, or the shapes of the front and back surfaces are specified, and an arbitrary outer shape cannot be selected.

  By the way, for example, donut-shaped rice crackers having a plate shape and a hole in the center can be produced by forming the dough into a desired shape and then drying and baking the dough. However, it is practically difficult to die-cut from the dough sheet into the desired shape for continuous production, even if the die-cutting means in the conventional line production is adopted as it is.

  That is, as described in Patent Documents 1 and 2, even if the surplus portion (perforated sheet) is separated after the die cutting of the dough sheet, the center hole portion of the dough remains as it is. For this reason, it is necessary to remove the central hole portion, but continuous separation is not possible with conventional devices.

  Accordingly, the present invention proposes a novel means for separating excess dough from the perforated portion inside the dough, and enables production of a perforated rice cracker line.

Moreover, the die cutting method of the rice cracker dough according to the present invention is a cutting roll provided with a protruding blade corresponding to the outer shape of the rice cracker produced as a predetermined dough sheet in the course of conveyance and the punching hole, and the outer shape advances. Die-cutting is performed so as to be continuous in a non-separated state before and after the direction, and after the die-cutting, the excess sheet of the outer portion of the outer shape of the rice cracker is separated by scraping, and the punched-hole surplus dough is cut The outer shape continuous fabric including this portion is transported in a state of being stretched from the state at the time of die cutting , and the portion of the punched hole surplus fabric is separated by air injection.

Thus, when the outer peripheral shape of the desired shape and the continuous outer fabric in which the outer peripheral shape is punched and cut are conveyed in an expanded state, the punched hole surplus fabric that has been cut in the periphery opens in the front and rear direction of the sheet. Therefore, it is easily and surely separated by air injection, and the non-separated parts of the outer shape continuous dough are separated and separated in the next drying step. When the dried dough is baked, a hole is formed. The produced rice crackers will be easily produced.

In as the configuration of the present invention described above, drain holes of a desired shape is bored in the center a plate-shaped, outer peripheral shape and vent hole shape can at various selected, visually interesting peculiar shape free before sub Rice confectionery can be obtained, and baking is efficiently done by the presence of the perforated holes, thereby providing a thick plate-shaped rice cracker that could not be realized in the past, and having a unique excellent texture A confectionery can be provided.

  Next, an embodiment of the present invention will be described. The shape of rice confectionery A1 and A2 to be produced is a flat plate that is flat on the front and back, as shown in Fig. 1, with holes a1 and a2 of the desired shape such as circular, diamond, and heart shaped inside. And the outer peripheral shape is a desired shape (circular, rectangular and other shapes) not related to the formation of the punched holes a1 and a2, and the dough sheet B is die-cut and die-cut. After the dough G has been subjected to a predetermined drying process, the dough G is produced by performing an arbitrary baking process such as a frying process or a baking process.

  The method of the present invention for performing the die cutting of the fabric G is performed in the order of the extending step, the cutting step, the surplus sheet separating step, and the punching hole forming step. Details of the configuration of the implementation apparatus will be described below, which includes the conveyance mechanism unit 2, the cutting mechanism unit 3, the surplus sheet separation mechanism unit 4, and the punch hole forming mechanism unit 5.

  The extension mechanism unit 1 includes a dumpling supply unit 11 and an extension roll 12 as in the conventional apparatus, and supplies a dough sheet B having a predetermined thickness and width to a transport conveyor (first transport conveyor) 21. Is.

  The transport mechanism unit 2 includes a transport conveyor (a first transport conveyor 21 and a second transport conveyor 22) and a next transport conveyor 23, and the first transport conveyor 21, the second transport conveyor 22, and the next transport conveyor 23 from the upstream side. Arranged in order.

  In particular, the first transport conveyor 21 and the second transport conveyor 22 connected to the next transport conveyor are provided, and the transport speed of the second transport conveyor 22 is set to be slightly faster than the first transport conveyor 21. Further, a gap b having a sufficient width is provided between the second transport conveyor 22 and the next transport conveyor 23 so that a punched hole surplus fabric F described later falls.

  The cutting mechanism unit 3 is basically the same as the conventional die cutting structure, and the first conveying conveyor 21 is sandwiched between the lower receiving roll 31 and the cutting roll 32 and cut above the cutting roll 32. A brush roll 33 that comes into contact with the roll 32 is arranged, and a water supply spray (or oil supply spray) 34 for the brush roll 33 is further arranged.

  The cutting roll 32 is provided with a protruding blade 321 corresponding to the outer peripheral shape of the rice cracker A to be produced on the outer peripheral surface and a protruding blade 322 corresponding to the shape of the punched hole a. In particular, the protruding blade 321 is a rice cracker. The outer circumferential shape is formed so that the front and rear in the traveling direction are continuous in a non-separated state.

  The surplus sheet separating mechanism 4 is composed of a discharge conveyor disposed above the first transport conveyor 21 or the second transport conveyor 22 and disposed so that the surplus sheet E can be easily transferred from the transport conveyor. Is. The surplus sheet E discharged by the discharge conveyor is returned to the dumpling supply unit 11 of the extending mechanism unit 1.

  The punching hole forming mechanism 5 is provided at a predetermined position above the gap b between the second transfer conveyor 22 and the next transfer conveyor 23, and an air jetting part 51 that jets air with a predetermined wind force downward, and the gap b The lower cloth receiving portion 52 that receives the punched excess cloth F and returns to the dumpling supply section 11, the sensor 53 that detects the progress of the outer shape continuous cloth D, and the sensor 53 detects the air blowing section 51. And a control unit 54 for controlling the ejection timing.

  Next, an embodiment of the method of the present invention will be described corresponding to the operation of the apparatus. In the extending step, the dumpling dough serving as the rice cracker dough G is formed into a dough sheet B by the extending roll 12 of the extending mechanism 1, and the dough sheet B is conveyed by the first conveyor 21.

  A cutting process makes the cutting sheet C by passing the cutting mechanism part 3 in the middle of conveyance, and the cutting sheet C cuts with the cutting | disconnection c cut | disconnected with the protruding blade corresponding to the outer periphery shape of rice cracker dough, A cut d cut by the projecting blade corresponding to the hole is made. In particular, the cut c corresponding to the outer circumferential shape is in a non-separated state in which the outer circumferential shape continues without traversing in the traveling direction.

  In the cutting step, moisture is applied (oil coating) to the surface of the cutting roll 32 via the brush roll 33 so that a part of the dough sheet B does not adhere to the cutting roll 32.

  In the surplus sheet separating step, when the cut sheet C reaches the position of the surplus sheet separating mechanism 4, the surplus sheet E is scraped off and separated from the conveying line by the discharge conveyor (surplus sheet separating mechanism 4), and the dumpling supply unit 11. It is carried out by returning to.

  The surplus sheet E is an elongated continuous dough corresponding to the shape between the continuous outer shape dough D that is lined up (the dough that has been cut into a shape in which the front and rear of the outer shape of the rice cracker are continuous in a non-separated state). It is peeled off from the cut sheet by the operation of the conveyor.

  When the cut sheet C further moves from the first transport conveyor 21 to the second transport conveyor 22, the second transport conveyor 22 is operating a little faster than the first transport conveyor 21, so that the transported cutting sheet C (contour continuous fabric) D) elongates in a slightly more advanced manner than at the time of cutting.

  In the punching hole forming step, the outer shape continuous dough D reaches between the second transport conveyor 22 and the next transport conveyor 23 provided with the punch hole forming mechanism 5, and is just a cut piece e (= the punched hole surplus cloth F). Is located at the position of the gap b, the punched-out excess fabric F is separated from the outer shape continuous fabric D by the air ejection of the air ejection portion 51 and dropped onto the receiving portion 51.

  In particular, the continuous outer fabric D conveyed at the speed of the second conveyor 22 is stretched, but the cut piece e (= excess hole fabric F) is conveyed in a discontinuous state. The front and rear portions are in an open state, and separation by air ejection is facilitated.

  Further, the air ejection timing is performed by detecting the progress of the outer shape continuous fabric D by the sensor 53, and the punched excess fabric F dropped on the receiving portion 52 is returned to the dumpling supply portion 11.

  When the cut piece e (= the punched hole surplus dough F) is separated from the outer shape continuous dough, it becomes a continuous rice cracker dough G, which is sent to the next drying step. The rice confectionery dough G that is continuous in this drying process is broken apart, and is made into a product through a baking process and a finishing process by conventional means.

  The rice cracker produced by the above means is a plate with a desired shape that is flat on the front and back sides, and has a hole of a desired shape such as a circle, a rhombus, a heart shape inside, and is visually interesting. In addition to having a certain appearance, the hole makes the firing efficiency good in the firing step, and the texture is also good.

  In addition, this invention is not limited to embodiment of the said apparatus and method, It cannot be overemphasized that a punching hole formation process may be implemented before a surplus sheet separation process, for example.

  Furthermore, the present invention is intended for rice crackers that use glutinous rice, but the present invention can be applied when adopting a processing step in which die cutting is performed from a dough sheet even if it is potato using glutinous rice. It is what is done.
