Description

  The present invention relates to a roll-shaped bread dough forming apparatus for forming bread dough, which is performed as a pretreatment for baking bread, into a roll shape.

  The bread making process is usually performed through the following processes.

After kneading the flour into bread dough, divide it into predetermined amounts, make it intermediate fermented,
The intermediate-fermented dough is passed between a plurality of pairs of rollers to degas, to make an oval or circular sheet dough,
While the sheet-like bread dough is further transported on the belt conveyor, the sheet-like bread dough is passed under the interdigital wire mesh that is in contact with the bread dough placing surface of the belt conveyor, thereby forming a spindle shape (that is, in the axial direction). A roll with a large central part and a small diameter at both ends)
Furthermore, this spindle-shaped bread dough conveyed on the belt conveyor is suppressed from the top by the spreading surface and rolled on the belt conveyor to extend it into a substantially cylindrical shape.
The bread dough having a cylindrical shape is placed on the top plate as it is, or after being secondarily formed, placed on the top plate for final fermentation, and finally put in an oven for baking.

  It is known that the above-mentioned pressure spreading surface for making a spindle-shaped roll of sheet-like bread dough into a cylindrical shape is formed by setting a plate for pressure spreading and an endless belt for pressure spreading in parallel to face the dough mounting surface. In recent years, it has become common to use an endless belt.

  Japanese Patent Application Laid-Open No. H10-228561 discloses a pressure spreading plate in which, for example, when a hard bread dough is spread and pressed, a portion of the bread dough having a middle thickness is pressed particularly strongly. Further, the applicant of the present application has applied for a patent for a bread dough pressure-applying device provided with an endless belt for pressure spreading, in which the middle thick portion of the bread dough is particularly strongly pressed and spread.

Utility Model Publication No. Sho 42-20720

  However, it has been found that these bread dough spreading devices have the following problems.

  That is, even if the bread dough wound in a spindle shape is spread by pressing the middle thick portion particularly strongly as described above, the bread dough discharged from the pressure spreading device does not become cylindrical, It may be the one that leaves the part. FIG. 6 illustrates this, and the bread dough 101 wound in a spindle shape is placed on the placing surface 102 of the belt conveyor and conveyed, and the pressure belt 103 and the pressure provided on the back of the belt are shown. The bread dough 101 is formed into a cylindrical shape through the pressure-applying portion 105 made up of the auxiliary plate 104, but the bread dough 101 'discharged from the pressure-applying portion has the middle thick portion 106 left. This is because when the dough that has been degassed and rolled into a sheet is rolled up, a large amount of air is entrapped in the center, and the air is not dispersed or released even when the pressure is applied. It is believed that there is.

  In order to solve this problem, there is a risk that the bread dough may be damaged if an attempt is made to apply pressure by applying a stronger pressure to the middle thick portion of the bread dough using a pressure spreading device.

  The present invention aims to solve such problems.

That is, the present invention
A belt conveyor having a placement surface for placing and transporting sheet-like bread dough, and a conveying direction of the bread dough by winding the sheet-like bread dough installed on the upstream side of the placement surface and rolling it A spindle-shaped winding part having an axis extending in a substantially perpendicular direction, and a spindle-shaped bread dough that is set at an upper position on the downstream side of the placement surface and is rolled between the placement surface. A roll-shaped bread dough forming apparatus having a pressure spreading section for extending the bread dough while being moved, and is set at a position above the pressure spreading surface between the winding section and the pressure spreading section and discharged from the winding section. are extended to press between the placing surface of the central portion of the fusiform dough entering pressure portion, the central portion is made to be valley which fell in surface-side placing said viewed from the opposite side portions A bread dough pressing member is provided.

  After the bread dough was pressed by the bread dough pressing member as described above, the bread dough was passed through the pressure-extended portion, and as a result, a substantially cylindrical bread dough having almost no middle thick portion could be obtained. This is presumably because the air that was thought to have been held in the central portion of the waterproof bread dough could be dispersed and released to both side portions by the above pressing.

In particular,
This bread dough pressing member may be a pressing surface that engages and presses the central portion of the bread dough, and has a pressing surface whose transverse section is curved in a convex shape toward the placement surface. In this case, the pressing surface can have a certain length in the dough conveying direction. The bread dough pressing member can be configured to be engaged with and pressed against the bread dough as a roller shape. However, the bread dough pressing member is pressed after a certain length in the dough conveying direction. The bread dough makes it possible to more effectively make the dough into a cylindrical shape.

  More specifically, the upstream portion of the pressing surface in the dough conveying direction is a tapered surface that tapers toward the upstream, and the tip thereof is higher than the height of the spindle-shaped dough discharged from the winding portion. It is preferable that the position is high. This is so that the bread dough smoothly enters under the dough pressing member.

The present invention also provides
A belt conveyor having a placement surface for placing and conveying sheet-shaped bread dough;
A winding part installed upstream of the placement surface and wound into a roll shape by rolling the sheet-like bread dough being conveyed into a spindle shape having an axis extending in a direction substantially perpendicular to the conveying direction of the bread dough;
A pressure spreading section for extending the bread dough into a cylindrical shape while rolling the bread dough between the placement surface, which is set at an upper position on the downstream side of the placement surface;
Bread dough pressing member as described above,
A roll-shaped bread dough forming apparatus is provided.

The spindle-shaped dough is made substantially cylindrical by the bread dough pressing member and the pressure spreading portion.
Specifically, the pressure spreading section is
An endless belt for pressure development set at an upper position on the downstream side of the placement surface, having a pressure development surface substantially parallel to the placement surface, and the pressure development surface in the driving direction of the placement surface It can be driven (the pressure spreading surface can be in the downstream direction or the upstream direction in the bread dough conveying direction), and the cylindrical dough is rolled while being pinched between the spindle-shaped bread dough and the mounting surface. An endless belt for spreading pressure to extend the bread dough,
The pressing surface is applied to the pressing surface from the back side by applying a pressing force toward the central portion in the axial direction of the bread dough that is set on the back side of the pressing surface and extends in a cylindrical shape by the pressing surface. It is possible to provide a pressing assisting member having a pressing assisting surface that is curved so that the central portion in the width direction is convex toward the bread dough and presses the bread dough.

  The pressing auxiliary member prevents the center of the dough, which has been described above by the dough pressing member, from returning to the middle thickness state.

  The present invention provides a bread dough pressing member as described above and a roll-shaped bread forming apparatus using the same, but essentially a spindle-shaped bread dough obtained by winding a sheet-shaped bread dough into a roll shape is substantially provided. In a roll bread dough forming method that rolls between two parallel surfaces to form a cylindrical shape, the substantially parallel portion of the spindle-shaped bread dough is recessed in a valley shape when viewed from both sides. The present invention provides a method for forming a roll-shaped bread dough that is sandwiched between the two.

  Such a method is a novel method which has not been seen at all in the past, and has the excellent effects as described above.

  Hereinafter, embodiments of a bread dough forming apparatus according to the present invention will be described with reference to the drawings.

As shown in the figure, the roll-shaped bread dough forming apparatus 1 according to this embodiment includes a belt conveyor 10 that carries the bread dough a and conveys the bread dough a on the belt conveyor. A winding part 20 having a comb-like winding member 12 set so as to be in contact with 11 and making the dough a spindle-shaped roll, and a downstream side of the winding part of the mounting surface 11 In order to extend the bread dough a, which is a spindle-shaped roll provided with an endless belt 26 (FIG. 2) for pressure spreading set in parallel with an interval upward, while rolling between the placement surface 11 and a cylindrical shape. The center part b of the spindle-shaped bread dough a that is set between the spreading part 24, the winding part 20 and the endless belt 26 for spreading and discharged from the winding part 20 and enters the endless belt 26 for spreading is shown in FIG. As shown in Figure 3, And pressed between the surface 11, so that the central portion is depressed valley to look mounting surface 11 side from the both side portions, and a dough pressing member 27.

  The part related to the subject of the present invention described in the problem to be solved by the invention is mainly in the bread dough pressing member 27. First, the winding part 20 will be described.

  The winding part 20 is provided on each side of the bread dough conveying path between the interdigital winding member 12 and the interdigital winding member 12 and the placement surface 11 provided along the three rows of bread dough conveying paths. A pair of guide members 14 set.

  The interdigital winding member 12 includes a pair of brackets 30 attached to the frames 70 on both sides of the belt conveyor 10, and attachment shafts 32, 34, which are hung on the brackets and cross over the upper position of the belt conveyor mounting surface 11. 36, three interdigital members 38, 40, and 42 (FIG. 2) that are respectively attached to the belt conveyor and extend downstream from the belt conveyor, specifically, a flexible wire mesh.

  The first interdigital member 38 from the upstream side is for starting to roll the bread dough into a roll shape from its tip by contacting the sheet-like bread dough a being conveyed, and the second interdigital member Reference numeral 40 is placed on the first interdigital member 38 and weights the first interdigital member 38 that comes into contact with the bread dough to ensure the start of the dough winding. The second interdigital member 40 extends downstream from the first interdigital member 38 and extends between the upstream ends of the pair of guide members 14. The third interdigital member 42 extends downstream so as to be placed on the guide member 14, and extends to the vicinity of the endless belt 26 for pressure expansion as a pressure expansion member.

  The shafts 32, 34, and 36 are spaced from the placement surface 11 enough to receive the bread dough a conveyed from the upstream side. In the guide member 14, the third interdigital member 42 placed thereon comes into contact with the bread dough started to be wound by the first and second interdigital members 38, 40, and the dough is further wound. The height is such that it can be rolled.

  It is not always necessary to use three interdigital members. Even if one interdigital member is used, it is only necessary to ensure that the dough supplied from the upstream can be wound at the upstream end portion.

  The pair of guide members 14 are attached to frames 70 on both sides of the belt conveyor 10 and supported by support frames 44 set so as to cross the belt conveyor 10. The support frame 44 is attached in parallel to the cross bar 46 corresponding to a pair of cross bars 46 provided at intervals in the bread dough transport direction and the guide members 14 forming a pair of each transport path. A support bar 48, and a support adjusting member 50 which is set so as to be slidable between the support bar 48 and the crossing bar 46, supports the corresponding guide member 14, and adjusts the position of the guide member with respect to the conveyance path. Have.

  As shown in FIG. 1, the pair of guide members 14 are configured such that the distance between the guide members 14 gradually decreases from the upstream side to the downstream side of the conveyance path. That is, the bread dough supplied from the upstream side has variations in the position in the width direction of the belt conveyor, so even if there is bread dough supplied out of the conveyance path, it is received at the upstream end that accepts it. As the bread dough is conveyed to the downstream side, the bread dough is brought closer to the conveyance path, and finally the bread dough is sent to the pressure-pressing section 24 on the downstream side in a state aligned with the conveyance path. To be able to. The adjustment of the misalignment of the bread dough by the guide member is performed by rotating the bread dough in a spindle shape, so that the bread dough is tilted by contact with the guide member (that is, the center axis of the bread dough wound in the spindle shape is conveyed). In the present invention, since the interdigital member suppresses the bread dough, it is confirmed that the position adjustment is performed without substantially such inclination. doing.

  As described above, the pressure-expanding portion 24 has the pressure-endless endless belt 26 set at a position above the placement surface 11 of the belt conveyor downstream of the winding portion 20. Guide members 57 set on both sides of each conveying path for bread dough are provided between the placing surface 11 of the belt conveyor and the spreading surface of the spreading endless belt 26 adjacent to the placing surface. The bread dough passed through the pressure part 24 is guided, and both end faces of the bread dough that are spread in a cylindrical shape are formed.

  The bread dough pressing member 27 is attached to a support bar 64 installed between the frames 70 on both sides of the belt conveyor 10 so as to align with the bread dough conveying path, and as shown in FIG. It has a pressing surface 60 that curves in a convex shape toward the surface and extends in the dough conveying direction. An upstream side portion of the pressing surface 60 in the bread dough conveying direction is a tapered surface 62 that is tapered toward the upstream, and a tip thereof is higher than the height of the spindle-shaped bread dough a discharged from the winding unit 20. Has been.

  FIG. 4 shows a process in which the bread dough a wound in a spindle shape at the winding part 20 is formed into a cylindrical shape by the bread dough pressing member 27 and the pressureless endless belt 26 of the pressure spreading part 24.

  That is, the bread dough a (FIG. 5 (1)) wound in the spindle shape discharged from the winding part 20 is first passed under the bread dough pressing member 27 (FIG. 5 (2)). The bread dough pressing member 27 is aligned with the center position in the width direction of each bread dough conveying path of the winding portion, and engages and presses the central portion of the bread dough a being conveyed. As shown in FIG. 5, the bread dough a passed under the bread dough pressing member 27 has a valley shape in which the central portion b falls toward the pressure-extended surface 11 when viewed from the both side portions c. The bread dough is then conveyed under the endless belt 26 for spreading (FIG. 5 (3)). The pressureless endless belt 26 includes a plate-like pressing auxiliary member 29 on the back surface thereof, and presses the bread dough a together with the conveying surface 11 together with the pressing auxiliary member 29. The conveyance surface 11 and the pressureless endless belt are driven with a speed difference, and the bread dough is rolled at a predetermined rotational speed so as to be nearly cylindrical as a whole (FIG. 5 (3)). The pressing auxiliary member 29 has a step portion 31 directed toward the central portion b of the bread dough on the downstream side thereof, and presses the central portion b of the bread dough made to be cylindrical more strongly than the both side portions c. Through such a process, the bread dough a discharged from the endless belt for spreading is substantially cylindrical as shown in FIG.

  As mentioned above, although one Embodiment of the bread dough roll forming apparatus which concerns on this invention was described, this invention is not limited to this, For example, the bread dough press member 27 has the axis line extended in the direction which crosses the conveyance surface 11. As a roller-shaped one that is rotatable at the center, the roller can be engaged and pressed against the bread dough while rotating.
