Description

[Technical field]

[0001] The present invention relates to a bread dough dividing and shaping tool, a bread dough dividing and shaping device equipped with the same, and a method for producing bread dough. [Background technology]

[0002] When bread is mass-produced industrially, as disclosed in Patent Document 1, bread dough can be produced by preparing a relatively large size loaf of dough, dividing the prepared loaf of dough using a device such as a divider, and then molding the divided loaves of dough. In particular, in recent years, interest in reducing food loss and food waste has increased, and there is an increasing demand for small-sized bread that can be "eaten in one sitting" (for example, table rolls and sizes even smaller than table rolls (for example, bite-sized)), and there is a demand for industrial mass production of such small-sized bread dough. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-148689 A Summary of the Invention [Problem to be solved by the invention]

[0004] Small-sized bread dough is often sold in multiple bags, and the bread-making process is required to produce more pieces of dough than regular-sized dough. However, there is an upper limit to the dividing speed of the divider that divides the dough, and when dividing the dough into 40g pieces, for example, the amount of dough that can be processed per hour is reduced to about half that of when dividing into 80g pieces. For this reason, when making small-sized bread, the dividing process becomes a bottleneck (rate-limiting step) in the entire bread-making process from kneading the dough to baking (or frying, steaming, etc.).

[0005] The present invention aims to provide a bread dough dividing and shaping tool, a bread dough dividing and shaping device equipped with the same, and a method for producing bread dough, which can increase the production speed of bread dough in the bread making process and produce bread dough efficiently, even when producing small amounts of bread dough. [Means for solving the problem]

[0006] (1) The dough dividing and shaping tool of the present invention is a dividing and shaping tool for dividing and shaping dough transported on a conveyor, and has a rod-like or plate-like shape extending in one direction, and has, in the extending direction, a dividing section for dividing the dough and a guide section for shaping the divided dough, and the lower side of the dividing section is inclined so that the angle between the lower side of the dividing section and an extension line of the lower side of the guide section toward the dividing section is an acute angle. (2) The split molding tool may have a width in the extending direction of 5 to 30 mm. (3) In the above-mentioned split molding tool, the split portion may be configured so that the lower side is rounded. (4) In the above split molding tool, the length of the guide portion in the extending direction may be 1.5 times or more the length of the split portion. (5) In the above split molding tool, the guide portion may be a substantially linear, elongated member. (6) In the above-mentioned split molding tool, the split portion may be a substantially linear, elongated member. (7) The bread dough dividing and shaping device of the present invention comprises a conveyor for transporting bread dough, a spreading member arranged opposite the conveyor, and the above-mentioned dividing and shaping tool, wherein the dividing and shaping tool is positioned so that when the bread dough is transported from the upstream side to the downstream side, the dividing section is located on the upstream side and the guide section is located on the downstream side. (8) In the above-mentioned split molding device, a joint portion between the dividing portion of the split molding tool and the guide portion may be configured to be located between the conveyor and the spreading member. (9) A method for producing bread dough according to the present invention includes a dividing and forming tool having a guide section extending in the conveying direction of a conveyor and a dividing section extending in the conveying direction of the conveyor and extending diagonally upward from the upstream end of the guide section relative to the conveying direction of the conveyor, the guide section is arranged close to the conveying surface of the conveyor, the bread dough being divided at or near the junction between the guide section and the dividing section, and the divided bread dough is formed in the guide section. (10) In the above-mentioned method for producing bread dough, a configuration may be adopted in which a disk-shaped or sheet-shaped dough is rolled up to form a roll-shaped dough, and then the roll-shaped dough is divided using the dividing and forming tool. Effect of the Invention

[0007] According to the present invention, the dough is divided by the dividing section of the dividing and shaping tool, and the divided dough is shaped by the guide section, so that the dough can be divided in the shaping process. This allows the dough to be divided into pieces larger than the final dough size in the dividing process, which is a bottleneck in the bread making process, so that the amount of dough that can be processed per unit time in the bread making process can be increased, and as a result, small dough pieces can be efficiently produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a dividing and shaping device 1 having a dividing and shaping tool 21 that divides and shapes bread dough will be described as an example. The dividing and shaping device 1 according to this embodiment is a device for industrially producing small-sized bread dough, and as shown in FIG. 1(A), the bread dough divided by a divider into larger sizes is further divided and shaped in the shaping process. Conventionally, when small-sized bread dough (for example, 40g bread dough) is industrially produced, a method has been adopted in which the bread dough is divided into desired sizes (for example, 40g) by a divider as shown in FIG. 1(B), and then the divided bread dough is shaped. In contrast, in the dividing and shaping device 1 according to this embodiment, as shown in FIG. 1(A), the bread dough divided by the divider can be further divided in the shaping process, so that the divider can divide the bread dough into larger sizes (for example, 80g) than the desired size (for example, 40g). This allows the amount of dough to be increased in the dough dividing process using a divider, which is a bottleneck in the bread-making process, and makes it possible to improve the efficiency of dough production. In particular, the dividing and molding tool according to the present invention can be easily attached to a conventional molding device, making it possible to efficiently produce small amounts of bread dough at low cost.

[0010] The dividing and molding device 1 according to this embodiment will be described below. FIG. 2(A) is a plan view of the dividing and molding device 1 according to this embodiment, and FIG. 2(B) is a side view of the dividing and molding device 1 according to this embodiment. The dividing and molding device 1 according to this embodiment receives bread dough divided by a divider (or bread dough manually divided into pieces of a predetermined size), and the dough is shaped and divided. To perform this function, the dividing and molding device 1 according to this embodiment has a conveyor 10 and a dividing and molding section 20. In addition, in FIGS. 2(A) and (B), the conveying direction of the dough is indicated as D, and in the following description, the conveying source side (right side in FIG. 2) is the upstream side, and the conveying destination side (left side in FIG. 2) is the downstream side in the conveying direction.

[0011] The dividing and molding apparatus 1 according to this embodiment is an apparatus that divides and shapes the conveyed bread dough, and the conveyed bread dough can be divided into appropriate sizes in advance, either manually or using a device such as a divider, so that the dividing and molding apparatus 1 can produce bread dough of the desired size (a size smaller than before being fed into the dividing and molding apparatus 1). The dividing and molding apparatus 1 according to this embodiment may be configured to divide and mold dough that has already been shaped into a round shape, or it may be configured to roll up sheet-shaped dough using a roller or the like, and divide and mold the rolled dough.

[0012] The conveyor 10 is a belt conveyor that transports dough from the upstream side to the downstream side. The conveyor 10 may be composed of a single conveyor 10, or may be composed of a plurality of conveyors 10 connected together. The conveyor 10 may be composed of an endless belt that circulates, and the circulation speed of the endless belt can be appropriately adjusted.

[0013] The dividing and shaping section 20 divides and shapes the dough conveyed by the conveyor 10 while it is conveyed. In this embodiment, as shown in Figs. 2(A) and (B), the dividing and shaping section 20 has a dividing and shaping tool 21, a spreading member 22, a guide 23, and supports 24 and 25, and the dividing and shaping tool 21 divides the dough, and the dividing and shaping tool 21, the spreading member 22, and the guide 23 shape the dough. The dividing and shaping tool 21 and the guide 23 are connected at one end to the support 24 and at the other end to the support 25, so that they are arranged above and in the vicinity of the conveying surface 11 of the conveyor 10 without contacting the conveying surface 11. However, the dividing and shaping tool 21 or the guide 23 may be configured so that a part or the whole of them are temporarily or permanently in contact with the conveying surface 11 of the conveyor 10. In this case, the dividing and shaping tool 21 or the guide 23 corresponds to the configuration arranged above and in the vicinity of the conveying surface 11.

[0014] Here, Fig. 3 is a diagram showing the split molding tool 21 according to this embodiment, Fig. 3(A) is a side view of the split molding tool 21, Fig. 3(B) is a front view of the split molding tool 21, Fig. 3(C) is a rear view of the split molding tool 21, and Fig. 3(D) is a plan view of the split molding tool 21. Fig. 3(E) is a cross-sectional view of the split molding tool 21, showing a cross-section along line EE in Fig. 3(A). Fig. 4 is a diagram for explaining the arrangement of the split molding tool 21, Fig. 4(A) is a diagram for explaining the arrangement relationship between the split molding tool 21 and the conveying surface 11 of the conveyor 10, and Fig. 4(B) is a diagram for explaining the arrangement relationship between the split molding tool 21 and the conveyor 10 and the spreading member 22.

[0015] As shown in Fig. 3(A), the split molding tool 21 has a rod-like shape extending in one direction, and has a dividing portion 211 and a guide portion 212 in the extending direction. As shown in Fig. 3(A), the split molding tool 21 has a rod-like shape as a whole, since the dividing portion 211 and the guide portion 212 each have a substantially rod-like shape. In addition, the split molding tool 21 according to this embodiment has a bent shape at a joint portion 213 between the dividing portion 211 and the guide portion 212.

[0016] 2 and 4(B), the dividing molding tool 21 according to this embodiment is connected to supports 24, 25 erected on the outside of the conveying surface 11 of the conveyor 10, and is disposed above and in the vicinity of the conveying surface 11 of the conveyor 10 along the conveying direction of the conveyor 10. Specifically, the dividing molding tool 21 is disposed so that the dividing section 211 is located on the upstream side of the conveying direction of the conveyor 10, and the guide section 212 is located on the downstream side of the conveying direction of the conveyor 10. As a result, the bread dough conveyed by the conveyor 10 is conveyed from the dividing section 211 side toward the guide section 212 side, divided into two by the dividing section 211, and then shaped by the guide section 212.

[0017] In this embodiment, the dividing molding tool 21 is arranged so that the dividing portion 211 is inclined as shown in FIG. 4(A). Specifically, the lower side 214 of the dividing portion 211 is formed so that the angle θ between the lower side 214 of the dividing portion 211 and the extension line EL of the lower side 215 of the guide portion 212 toward the dividing portion 211 is an acute angle. Then, by arranging the dividing molding tool 21 so that the angle between the lower side 214 of the dividing portion and the conveying surface 11 of the conveyor 10 is an acute angle as shown in FIG. 4(A), the dividing molding tool 21 can divide the dough by pressing it from above with the dividing portion 211 as the dough is conveyed by the conveyor 10 (because stress can be applied from two directions, the upward direction and the conveying direction), compared to when stress is applied to the dough from only one direction, the dough can be prevented from crumbling significantly, and the adhesion of the dough to the dividing portion 211 can be effectively reduced.

[0018] Furthermore, in this embodiment, as shown in FIG. 3(E), at least the lower side 214 of the dividing section 211 of the dividing and forming tool 21 has a rounded shape. Specifically, the lower side 214 of the dividing section 211, which abuts against the dough conveyed in the conveying direction D, has a width W of 5 to 30 mm, more preferably 10 to 20 mm, and is curved or arc-shaped in the width W direction. As a result, the cut surface of the dough divided by the dividing section 211 is not sharp, but is rounded, making it easier to shape the dough into a round shape by the guide section 212. In this way, this embodiment is characterized in that the dough is not cut by a sharp cutter or the like, but is divided by pushing the dough through the rounded rod-shaped dividing section 211. In this embodiment, the lower edge 214 of the dividing portion 211 has a constant width W, and the surface that comes into contact with the dough is curved or arc-shaped, which makes it easier to disperse the shear force when dividing the dough. However, as described above, by pressing the dough from above with the dividing portion 211, the shear force can be increased, effectively reducing the adhesion of the dough to the dividing portion 211.

[0019] Furthermore, in this embodiment, the dividing and shaping tool 21 is configured such that the guide portion 212 is longer than the dividing portion 211 in the conveying direction D. The lengths of the dividing portion 211 and the guide portion 212 are, as shown in FIG. 4(A), the length L1 of the dividing portion 211 in the conveying direction and the length L2 of the guide portion 212 in the conveying direction. For example, the length L2 of the guide portion 212 can be 1.5 times or more longer than the length L1 of the dividing portion 211. In this way, by lengthening the guide portion 212, it becomes possible to form the divided surface of the divided dough more roundly. Furthermore, in this embodiment, as shown in FIG. 2(A), a guide 23 is installed in parallel with the dividing and shaping tool 21, and the surface opposite to the surface where the dough is divided abuts against the guide 23, so that the entire dough is formed into a round shape.

[0020] 2 and 4, in this embodiment, the joint portion 213 between the dividing portion 211 and the guide portion 212 of the dividing molding tool 21 is disposed between the transport surface 11 of the conveyor 10 and the spreading member 22. By disposing the joint portion 213 of the dividing molding tool 21 between the transport surface 11 of the conveyor 10 and the spreading member 22, even if the shape of the dough is partially distorted when the dough is divided by the dividing molding tool 21, not only can the guide portion 212 and the guide 23 shape the dough in the left-right direction, but the spreading member 22 can also shape the dough in the up-down direction at the same time.

[0021] As shown in FIG. 2(A), the dividing and molding device 1 according to the present embodiment has two dividing and molding tools 21, and each dividing and molding tool 21 divides the dough into two (two-row configuration), but the present embodiment is not limited to this configuration, and may have a single dividing and molding tool 21 (one-row configuration), or may have three or more dividing and molding tools 21. The dividing and molding device 1 according to the present embodiment has a configuration in which one dough is divided into two using one dividing and molding tool 21, but the present embodiment is not limited to this configuration, and may have two or more dividing and molding tools 21 arranged between the guides 23, and may divide one dough into three or more using two or more dividing and molding tools 21. Furthermore, the dough divided by the dividing and molding tool 21 may be further divided using another dividing and molding tool 21 on the downstream side.

[0022] In this embodiment, the spreading member 22 has an endless belt 220. The endless belt 220 of the spreading member 22 may be configured to not circulate or to circulate. When the endless belt 220 is configured to circulate, it is preferable that the circulation direction D1 of the endless belt 220 with which the dough comes into contact is opposite to the circulation direction D2 of the conveying surface 11 of the conveyor 10 with which the dough comes into contact, as shown in FIG. 4(B). This increases friction between the dough being conveyed on the conveyor 10, and allows the dough to be rolled more efficiently.

[0023] Next, a method for producing bread dough according to this embodiment will be described. Fig. 5 is a flow chart showing the method for producing bread dough according to this embodiment. In this embodiment, as shown in Fig. 5, first, in step S101, bread dough is produced. Note that the production of bread dough in step S101 can be performed by a general method, either manually by an operator or by using a machine such as a divider, without using the dividing and molding apparatus 1 according to this embodiment.

[0024] In step S102, the bread dough prepared in step S101 is put into the dividing and molding apparatus 1 by an operator or a machine. In this embodiment, the operator puts the bread dough prepared in step S101 into a hopper (not shown) of the dividing and molding apparatus 1, and in the following step S103, the put-in bread dough is placed on the conveyor 10 and transported by the conveyor 10 to the dividing and molding section 20. Then, in step S104, the bread dough transported to the dividing and molding section 20 is divided into several pieces by the dividing and molding tool 21 while being transported. Specifically, the bread dough transported by the conveyor 10 first comes into contact with the dividing section 211 of the dividing and molding tool 21, and as it is transported, it is divided into several pieces by the dividing section 211 while being pressed from above by the dividing section 211 and the spreading member 22.

[0025] Furthermore, in step S105, the dough divided in step S104 is shaped. In this embodiment, the dough divided by the dividing section 211 of the dividing molding tool 21 is conveyed while contacting the guide section 212 and the guide 23 of the dividing molding tool 21 in the left-right direction and the spreading member 22 and the conveying surface 11 of the conveyor 10 in the up-down direction, so that the divided surfaces of the dough are shaped so as to be closed.

[0026] As described above, the dividing and shaping device 1 according to this embodiment is disposed above the conveying surface 11 of the conveyor 10 and has a dividing and shaping tool 21 for dividing and shaping the dough conveyed on the conveyor 10. The dividing and shaping tool 21 has a dividing section 211 having an inclination such that the distance to the conveying surface 11 becomes shorter from the upstream side to the downstream side along which the dough is conveyed, and a guide section 212 extending from the downstream end of the dividing section 211 in the conveying direction of the conveyor 10. As a result, the dough conveyed by the conveyor 10 is divided by the dividing section 211 (particularly, the joint section 213 between the dividing section 211 and the guide section 212 or its vicinity) while being pressed from above by the dividing section 211 of the dividing and shaping tool 21. In addition, in this embodiment, it is only necessary to install the dividing and shaping tool 21 having a simple structure, instead of a member requiring power such as an electric cutter, and therefore it can be added inexpensively to an existing dough shaping device.

[0027] Although the preferred embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the description of the above embodiment. Various modifications and improvements can be made to the above embodiment, and such modifications and improvements are also included in the technical scope of the present invention.

[0028] For example, in the above-described embodiment, the dividing and forming tool 21 has a rod-like shape, but the invention is not limited to this, and the dividing and forming tool 31 may have a plate-like shape, for example, as shown in Fig. 6. In this case as well, the dough transported by the conveyor 10 is divided into two pieces while being pressed from above by the dividing section 311 having an acute inclination, and the divided surfaces of the dough are closed by the guide section 312 to form the dough.

[0029] In addition, in the above-described embodiment, a configuration in which the lower edge 214 of the dividing portion 211 of the dividing molding tool 21 is formed in a straight line is exemplified, but this configuration is not limited to this, and the lower edge 214 of the dividing portion 211 can also be formed in a curved shape.

[0030] Furthermore, in the above embodiment, the spreading member 22 is disposed above the dividing and forming tool 21, but the present invention is not limited to this configuration, and the spreading member 22 may not be provided. However, it is preferable to provide the spreading member 22 in order to shape the divided dough in the vertical direction as well. [Explanation of symbols]
