Method for adjusting the width of food dough

Abstract

The dough sheet (F3) is conveyed by a conveyor belt (2) driven at the same conveying speed and a receiving conveyor belt (3) disposed downstream therefrom. A first measurement value (S1) corresponding to the width of the dough sheet is measured and stored in the control device (5) (Pb) every first predetermined time interval (T1). The average value (SA) of the first measurement value between second predetermined time intervals (T2) is calculated, and the width setting value (SS) of the dough sheet is determined by the control device based on the average value (Pc). After determining the width setting value, a second measurement value (S2) corresponding to the width of the dough sheet is measured and the width setting value is compared with the second measurement value (Pd). When the second measurement value is less than the width setting value, the conveying speed (V3) of the receiving conveyor belt is set to be slower than the conveying speed (V2) of the conveyor belt to expand the width (Pe) of the dough sheet.

Description

[Technical Field]

[0001] This invention relates to a method for adjusting the width of continuous dough sheets, such as bread dough, using a dough width adjustment system. More specifically, this invention relates to a method for adjusting the width of continuous dough sheets to a predetermined width or greater. [Previous Technology]

[0002] Various methods for adjusting the width of continuous dough sheets have been proposed to date. Patent Document 1 discloses a strip-shaped food dough production machine, which includes: a dividing hopper for holding the food dough, a cutting device disposed at the lower opening of the dividing hopper, a conveying device disposed below the cutting device, an eccentric roller that intermittently presses the food dough from above, and a forming hopper with a group of hopper rollers arranged in opposition to each other. Patent Document 2 discloses a method in which continuously supplied dough is compressed to a certain thickness on a supply conveyor belt, and the resulting change in dough width is read. Based on the change data, the speed of the supply conveyor belt is changed to supply a certain volume of dough to a delivery conveyor belt running at a certain speed. Furthermore, the dough is further stretched on the delivery conveyor belt, and through continuous processing, continuous dough with a certain thickness and width is produced at a certain speed.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-289963 [Patent Document 2] Japanese Patent Application Publication No. 03-210142 [Summary of the Invention]

[0004] [Problem to be Solved by the Invention] In the apparatus of Patent Document 1, the overlapping portion of the stick-shaped food dough (the portion where the rear end of the stick-shaped food dough overlaps with the front end of the next stick-shaped food dough) conveyed by the conveying device is thicker and less stretchable than other portions because the stick-shaped food dough overlaps vertically. Therefore, when the food dough is formed into a sheet by a subsequent stretching device, there is a problem that the width of the overlapping portion of the dough becomes narrower than other portions. In addition, when the dough sheet is continuously rolled into a stick shape in the width direction by a rolling device located downstream, and then cut into dough sheets by a cutting device, the dough sheets including the narrow portions become lighter, resulting in the problem of dough sheets being wasted.

[0005] In the method of Patent Document 2, in order to adjust the height of the amorphous dough to a certain level, the change in the width of the dough is measured when the amorphous dough is compressed with a calendering roller, and the speed of the supply conveyor belt is changed according to the change in the width of the dough. Therefore, a device such as a calendering roller is required, which leads to the problem of the device becoming more complex.

[0006] To solve the above-mentioned problems and reduce product waste, the object of the present invention is to provide a method for adjusting the width of a continuous dough sheet to a predetermined width or more. [Means for solving the problem]

[0007] To achieve this objective, the present invention provides a method for adjusting the width of food dough, which is a method for adjusting the width of continuous dough sheets by means of a dough width adjustment system. The method is characterized in that the aforementioned dough width adjustment system includes: a conveyor belt for transporting the continuous dough sheets, a receiving conveyor belt adjacent to and disposed downstream of the conveyor belt, a measuring device disposed at the downstream end of the conveyor belt, and a control device. The method comprises (a) transporting the continuous dough sheets by driving the conveyor belt and the receiving conveyor belt at the same speed; (b) measuring the width of the continuous dough sheets by the measuring device, transmitting a first measurement value to the control device, and storing the first measurement value in the memory of the control device every first predetermined time interval; and (c) using the calculation means of the control device... (d) Based on the plurality of the first measurement values ​​stored in the memory means of the aforementioned control device at each of the aforementioned first predetermined time intervals, the average width of the aforementioned continuous dough sheet within the second predetermined time interval is calculated, and a set value for the width of the aforementioned continuous dough sheet is determined based on the aforementioned average value; (e) The second measurement value of the width of the aforementioned continuous dough sheet conveyed by the aforementioned conveyor belt, measured by the aforementioned measuring device, is transmitted to the aforementioned control device, and the aforementioned set value is compared with the aforementioned second measurement value by the calculation means of the aforementioned control device; (f) When the aforementioned second measurement value is less than the aforementioned set value, a speed difference is set between the conveying speed of the aforementioned conveyor belt and the conveying speed of the aforementioned receiving conveyor belt by the control means of the aforementioned control device, so as to adjust the width of the aforementioned continuous dough sheet to reach or exceed the aforementioned set value.

[0008] In addition, in the aforementioned step (e), the conveying speed of the aforementioned conveyor belt is made faster than the conveying speed of the aforementioned receiving conveyor belt.

[0009] In addition, in the aforementioned step (e), the conveying speed of the receiving conveyor belt is made slower than the conveying speed of the conveying conveyor belt.

[0010] In addition, in the aforementioned step (e), when the aforementioned second measurement value reaches or exceeds the aforementioned set value, the aforementioned control means of the aforementioned control device sets the conveying speed of the aforementioned conveyor belt and the conveying speed of the aforementioned receiving conveyor belt to be the same.

[0011] In addition, in the aforementioned step (e), the greater the difference between the aforementioned second measurement value and the aforementioned width setting value, the greater the speed difference between the aforementioned conveying speed of the conveying conveyor belt and the aforementioned receiving conveyor belt.

[0012] Furthermore, the aforementioned continuous dough sheet is formed by overlapping and connecting the front end of the next stick-shaped dough with the rear end of the stick-shaped dough to create a strip-shaped dough sheet. [Effects of the Invention]

[0013] According to the present invention, the width of continuous dough sheets can be adjusted to a predetermined width or more, thereby reducing product loss.

Implementation Method

[0015] Referring to Figures 1 to 4, the strip food dough forming apparatus 6 and the dough width adjustment system 1 will be described. In this embodiment, the dough sheet F3 is, for example, food dough such as bread dough or pastry dough.

[0016] The strip food dough forming device 6, which is disposed on the upstream side of the dough width adjustment system 1, includes: a main frame 60, a hopper 61, a dividing device 62 for dividing the block food dough F contained in the hopper 61 into rod-shaped food dough F1, a supply conveyor belt 63 for connecting the rod-shaped food dough F1 and supplying continuous rod-shaped food dough F2 to the downstream side, a forming roller device 64 for forming continuous rod-shaped food dough F2 and forming strip-shaped food dough (continuous dough sheet) F3, and a conveyor belt 65 for removing the strip-shaped food dough (continuous dough sheet) F3.

[0017] Hopper 61 is configured on the upper part of the main body frame 60 and is used to hold block-shaped food dough F. Hopper 61 includes a dough inlet configured on the upper part and a dough outlet configured on the bottom.

[0018] The dividing device 62 is configured at the bottom of the hopper 61 to divide the block-shaped food dough F contained in the hopper 61 into rod-shaped food dough F1, and to remove the rod-shaped food dough F1 downwards. In this embodiment, the dividing device 62 is, for example, the dividing blade device described in Patent Document 1. The dividing blade device includes two parallel star-shaped blades 61a, each star-shaped blade 61a including a rotating shaft and three blade edges mounted on the rotating shaft. By rotating the two rotating shafts in opposite directions at a predetermined angle (e.g., 120 degrees), the blade edges move from above to below, thereby dividing the block-shaped food dough F into rod-shaped food dough F1. Detailed description of known dividing blade devices is omitted.

[0019] The supply conveyor belt 63 is disposed below the dividing device 62 and is used to connect the stick-shaped food dough F1 that has been cut into a predetermined length by the dividing device 62 and is moved (fallen) downward, thereby forming a continuous stick-shaped food dough F2 to be connected to be conveyed in the conveying direction B.

[0020] The forming roller device 64 is disposed below the downstream end of the supply conveyor belt 63 to form continuous rod-shaped food dough F2, and to form strip-shaped food dough (continuous dough sheet) F3 of approximately a certain thickness. The forming roller device 64 includes eight rotating rollers 64a arranged in a V-shape, each of which is configured to rotate and periodically oscillate. Detailed description of the known forming roller device 64 is omitted.

[0021] The conveyor belt 65 is used to transport the food dough (continuous dough sheet) F3, which is formed into a strip of approximately a certain thickness by the forming roller device 64, in the transport direction A.

[0022] Next, the dough width adjustment system 1 for implementing the method of the present invention will be described. As shown in FIG1, the dough width adjustment system 1 includes: a conveyor belt 2 for conveying continuous dough sheets F3 in the conveying direction A, a receiving conveyor belt 3 disposed downstream of and adjacent to the conveyor belt 2, a measuring device 4 for measuring the width FW of the continuous dough sheets F3, and a control device 5.

[0023] The conveyor belt 2 is a belt conveyor with an endless conveyor belt 2a, which is disposed downstream of the strip food dough forming device 6. The conveyor belt 2a is driven to rotate at a conveying speed V2 by a drive pulley 2b driven by a drive motor (not shown).

[0024] The receiving conveyor belt 3 is configured to transfer the continuous dough sheet F3, which is transported from the conveyor belt 2, to a subsequent rolling device (not shown). The receiving conveyor belt 3 is a belt conveyor with an endless conveyor belt 3a. The conveyor belt 3a is configured to rotate at a conveying speed V3 using a drive pulley (not shown) driven by a drive motor (not shown). Ideally, the conveying speed V2 of the conveyor belt 2 and the conveying speed V3 of the receiving conveyor belt 3 should be substantially the same.

[0025] The measuring device 4 includes a dough width sensor 4a that detects the width FW of continuous dough sheets F3. The dough width sensor 4a is a photoelectric distance sensor disposed on both sides (ends) of the conveyor belt 2 in the width direction. Ideally, the dough width sensor 4a should be positioned at the downstream end of the conveyor belt 2 in the conveying direction A, but it can be arbitrarily configured as long as it can detect the width FW of continuous dough sheets F3.

[0026] The control device 5 controls the operation of the dough width adjustment system 1 and the strip food dough forming device 6, and may include, for example, a computer. The control device 5 includes: a memory unit (not shown) that stores data received from the dough width sensor 4a of the measuring device 4; a calculation unit (not shown) that performs calculations using the data; and a control unit (not shown) that controls the operation of the conveyor belt 2 (conveyor speed V2, etc.), the operation of the receiving conveyor belt 3 (conveyor speed V3, etc.), and the operation of the strip food dough forming device 6.

[0027] Next, the operation of the strip food dough forming apparatus 6 will be described. A block of food dough F is fed to the hopper 61 at the top of the strip food dough forming apparatus 6, and is divided into rod-shaped food dough F1 by a dividing device 62 located at the bottom of the hopper 61. The divided rod-shaped food dough F1 is fed to the supply conveyor belt 63 below the dividing device 62, and is conveyed in the conveying direction B by the supply conveyor belt 63. After the rod-shaped food dough F1 has moved only a predetermined distance and the supply conveyor belt 63 has stopped, the next rod-shaped food dough F1, divided by the dividing device 62, is fed to the supply conveyor belt 63. At this time, the front end of the next rod-shaped food dough F1 is overlapped with the rear end of the previous rod-shaped food dough F1 (overlapping manner). In this way, a continuous stream of rod-shaped food dough F2 can be fed to the forming roller apparatus 64. The continuous rod-shaped food dough F2 is formed into a strip-shaped food dough (continuous dough sheet) F3 by the forming roller device 64. The strip-shaped food dough (continuous dough sheet) F3 is then transported to the conveyor belt 2 of the downstream dough width adjustment system 1 by the conveyor belt 65.

[0028] In this embodiment, the continuous dough sheet is, for example, a strip-shaped dough sheet formed by overlapping and connecting the front end of the next stick-shaped dough with the rear end of the stick-shaped dough. That is, the continuous dough sheet is a continuous dough sheet having a portion (overlapping portion) where the front end of the next stick-shaped dough is overlapped with the rear end of the stick-shaped dough. However, the continuous dough sheet is not limited to this and can be of any form. For example, it can be a continuous dough sheet supplied from an extruder or a continuous mixer that can output continuous dough sheets, and it may not have an overlapping portion.

[0029] Next, referring to FIG5, the step of controlling (adjusting) the width FW of the continuous dough sheet F3 to a predetermined width (set dough width FS) or higher in the dough width adjustment system 1 will be described.

[0030] The continuous dough sheet F3 is conveyed (Pa) in the conveying direction A by the control device 5 driving the conveying conveyor belt 2 and the receiving conveyor belt 3 at the same conveying speed V2 and V3.

[0031] The width FW of a continuous dough sheet F3 is measured by a dough width sensor 4a disposed at the downstream end of the conveyor belt 2. The dough width sensor 4a transmits the measurement value (first measurement value S1) corresponding to the width FW of the continuous dough sheet F3 to the control device 5. The continuous dough sheet F3 is transported from the conveyor belt 2 to the receiving conveyor belt 3. The width FW of the continuous dough sheet F3 is repeatedly measured by the dough width sensor 4a, and the first measurement value S1 is transmitted to the control device 5. The control device 5 receives the first measurement value S1 and stores the first measurement value S1 in the memory unit (Pb) every first predetermined time T1.

[0032] Next, using the memorized multiple first measurement values ​​S1, the calculation unit calculates the average value SA of the width FW of the continuous dough sheets F3 during the second predetermined time T2. The average value SA is set as the width setting value SS(Pc) corresponding to the set dough width FS of the continuous dough sheets F3. The first predetermined time T1 is, for example, 1 second. The second predetermined time T2 is, for example, 60 seconds. The first predetermined time T1 and the second predetermined time T2 are not limited to these and can be changed arbitrarily. In addition, instead of using the average value SA as the width setting value SS, the value of the average value SA after correction (based on the average value SA) according to the characteristics of the food dough is used as the width setting value SS(Pc).

[0033] The properties of food dough (hardness, extensibility, etc.) inevitably vary depending on the production conditions. Therefore, in this embodiment, instead of pre-determining the dough width FS (width setting value SS), as described above, the width of actual continuous dough sheets F3 is measured, and the average value SA calculated based on this is used as the width setting value SS. In this way, the properties of the dough during production are automatically reflected in the device, saving the operator the trouble of re-entering the dough width FS setting each time.

[0034] After determining the set dough width FS (width setting value SS), the dough width sensor 4a then measures the width FW of the continuous dough sheet F3 and transmits the measurement value (second measurement value S2) corresponding to the width FW to the control device 5.

[0035] The calculation unit of the control device 5 compares the width FW (second measurement value S2) of the continuous dough sheets F3 with the aforementioned set dough width FS (width setting value SS) (Pd). In this embodiment, the width FW of the overlapping dough sheets F3 tends to be narrower. When the width FW (second measurement value S2) of the continuous dough sheets F3 is narrower than the set dough width FS (width setting value SS) (FW < FS), the control unit of the control device 5 will make the conveying speed V2 of the conveying conveyor belt 2 faster than the conveying speed V3 of the receiving conveyor belt 3 (V2 > V3) (Pe). That is, the conveying speed V3 of the receiving conveyor belt 3 is set to be slower than the conveying speed V2 of the conveying conveyor belt 2. In detail, the calculation unit uses the difference between the set dough width FS (width setting value SS) and the width FW (second measurement value S2) of the continuous dough sheets F3 to determine a correction value and determine the conveying speed V2 of the conveying conveyor belt 2. The correction value can be appropriately changed according to the characteristics of the continuous dough sheet F3. Specifically, when the set dough width FS (width setting value SS) is set to 400mm, if the width FW (second measurement value S2) of the continuous dough sheet F3 is 380mm, the control device 5 will change the conveying speed V2 of the conveying conveyor belt 2 from 2m / min to, for example, 3.2m / min without changing the conveying speed V3 of the receiving conveyor belt 3 to 2m / min.

[0036] Thus, when the width FW (second measurement S2) of the continuous dough sheet F3 is narrower than the set dough width FS (width setting value SS) (FW < FS), the control unit of the control device 5 will make the conveying speed V2 of the conveying conveyor belt 2 faster than the conveying speed V3 of the receiving conveyor belt 3. In addition, the control unit of the control device 5 can also control the conveying speed V2 of the conveying conveyor belt 2 to be faster when the difference between the width FW (second measurement S2) of the continuous dough sheet F3 and the set dough width FS (width setting value SS) is larger. Specifically, when the set dough width FS (width setting value SS) is set to 400 mm, if the width FW (second measurement S2) of the continuous dough sheet F3 is 350 mm, the control unit will change the conveying speed V2 of the conveying conveyor belt 2 from 2 m / min to, for example, 5 m / min without changing the conveying speed V3 of the receiving conveyor belt 3 to 2 m / min.

[0037] When the conveying speed V2 of the conveying conveyor belt 2 increases relative to the conveying speed V3 of the receiving conveyor belt 3, the continuous dough sheet F3 will be pushed from upstream to downstream during the transition from the conveying conveyor belt 2 to the receiving conveyor belt 3. In this way, the width FW of the continuous dough sheet F3 can be extended along the width direction C orthogonal to the conveying direction A.

[0038] Subsequently, when the width FW (second measurement value S2) of the continuous dough sheet F3 reaches or exceeds the set dough width FS (width setting value SS) (FW ≥ FS), the control unit of the control device 5 will change the conveying speed V2 of the conveying belt 2 to the same speed as the conveying speed V3 of the receiving conveyor belt 3 (V2 = V3) (Pf). It is ideal to execute this change immediately. When the conveying speed V2 of the conveying belt 2 is accelerated relative to the conveying speed V3 of the receiving conveyor belt 3, and the state of extending the width FW of the continuous dough sheet F3 continues, during the period until the conveying speed V2 of the conveying belt 2 is adjusted to be the same as the conveying speed V3 of the receiving conveyor belt 3, there may be a situation where the width FW of the continuous dough sheet F3 is over-extended.

[0039] The purpose of this invention is to widen the narrow portion of the dough sheet. When the width FW (second measurement value S2) of the continuous dough sheet F3 detected by the dough width sensor 4a reaches or exceeds the set dough width FS (width setting value SS) (FW≧FS), the control unit of the control device 5 maintains the conveying speed V2 of the conveying belt 2 and the conveying speed V3 of the receiving conveyor belt 3 at the same speed (V2=V3) to prevent the width of the dough sheet from not changing.

[0040] Additionally, as shown in FIG3, a dough recycling system 7 can also be provided on the receiving conveyor belt 3. The dough recycling system 7, as a known system, includes a cutting device that cuts off the two sides of dough FE that are located further out (beyond) than the set dough width FS. When the width FW of a continuous dough sheet F3 is wider than (greater than) the set dough width FS (FW > FS), it is necessary to cut off the two sides of dough FE that are located further out (beyond) than the set dough width FS. By recycling the two sides of dough FE using the dough recycling system 7, they can be reused, and the recycled dough does not cause loss.

[0041] With this structure, continuous dough sheets F3 with a width FW of at least a set dough width FS can be supplied from the receiving conveyor belt 3 to the subsequent rolling device. Therefore, since continuous dough sheets F3 with a width FW of at least a set dough width FS can be formed by the subsequent rolling device, product waste can be reduced.

[0042] The description of the food dough width adjustment method of the embodiment of the present invention is generally as described above, but the present invention is not limited thereto, and various modifications can be made within the scope of the patent application.

[0043] In an embodiment of the present invention, a strip-shaped food dough forming device is used to overlap the rear end of a stick-shaped food dough with the front end of the next stick-shaped food dough to form an overlapping portion. In a variation, a conveyor belt may be provided upstream of the conveyor belt 2, and the front end of the next strip-shaped food dough may be manually connected to the rear end of the strip-shaped food dough in an overlapping manner on the conveying surface of the conveyor belt to form a continuous dough sheet with an overlapping portion.

[0044] The dough width sensor 4a is a photoelectric distance sensor in the above embodiment, but it is not limited to this and may also be a camera or the like disposed above the conveyor belt 2.

[0045] When the width FW of the continuous dough sheet F3 is narrower than (less than) the set dough width FS (FW < FS), in the above embodiment, although the conveying speed V2 of the conveying conveyor belt 2 is increased without changing the conveying speed V3 of the receiving conveyor belt 3 (V2 > V3), conversely, the conveying speed V3 of the receiving conveyor belt 3 can be made slower than the conveying speed V2 of the conveying conveyor belt 2 (V3 < V2) without changing the conveying speed of the conveying conveyor belt 2.

[0046] In the dough width adjustment system 1, although a speed difference is set between the conveying speed V2 of the conveying conveyor belt 2 and the conveying speed V3 of the receiving conveyor belt 3 at the transition point between the conveying conveyor belt 2 and the receiving conveyor belt 3, so that the width FW of the continuous dough sheet F3 reaches or exceeds the set dough width FS, as shown in FIG4, the receiving conveyor belt 3 can also be omitted, and an extension device 8 can be provided on the conveying conveyor belt 2. In this case, when the width FW of the continuous dough sheet F3 is less than the set dough width FS (FW < FS), the control device 5 will reduce the gap between the conveying conveyor belt 2 and the extension device 8, so that the width FW of the continuous dough sheet F3 is greater than the set dough width FS, thus extending the continuous dough sheet F3.

[0047] In the above embodiment, the dough width sensor 4a is disposed at the downstream end of the conveyor belt 2. Alternatively, a dough width confirmation sensor for measuring the width FW of consecutive dough sheets F3 after the dough width has been adjusted in the above manner can be disposed on the receiving conveyor belt 3. By means of this dough width confirmation sensor, it can be confirmed that the width FW of consecutive dough sheets F3 after the dough width adjustment is wider (greater than) the set dough width FS. In addition, it is also possible to compare how much the dough width has changed (adjusted) between before and after the dough width adjustment, and accordingly change the correction value for the conveying speed V2 of the conveyor belt 2.
