Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a rounding blade for an umbrella-shaped rounding machine used for rolling dough balls in a bread making and confectionery process.

[Conventional technology]

As is well known, in the so-called finishing (make-up) stage of the bread and confectionery process, dough balls that have been divided into predetermined sizes by machine or manual division are used as a pre-process before being transferred to the bench (intermediate fermentation) process. , a rounding process is provided. This rounding process involves rolling the irregularly shaped divided dough into a spherical shape so that the shaping process after the next bench process can flow smoothly, and stretching the surface of the dough ball during rolling to make it thinner. To reduce stickiness by forming a uniform film so that it does not stick on the bench in the next process, and
In order to prevent the gas generated by the yeast from leaking during the benching process in the next process, it is necessary to close the cut edges of the dough ball that were damaged when it was divided in the previous process, and to correct the disturbance of the gluten structure during division in the direction of the network structure. The purpose is to correct this.

As shown in FIGS. 4 to 6, the conventional umbrella-shaped rounding machine 1 used in this rounding process includes a truncated cone-shaped umbrella mold 3 rotatably installed on a base 2, and this umbrella mold 3. An umbrella surface 4 formed on the surface of
The main component is a round blade 5 installed at the top so as to spiral from the bottom to the top. A main shaft 6 is connected to a drive device housed in the base 2 and connected to the center of the umbrella mold 3 in order to rotate the umbrella mold 3.
Round blade support arms 8 are provided at regular intervals on the periphery of the spindle disk portion 7 fitted to the upper end of the main shaft disk portion 7 . A mounting rod 9 for holding and fixing the round blade 5 is provided at the tip of each of the round blade support arms 8. Further, near the upper end of the round blade 5 and above the umbrella surface 4, a powder sieve 1 is provided.
0. Motors 11 and 2 that operate this powder sieve machine 10
A single ball discharge guide 12 and a dough ball exit chute 13 are provided, respectively. Further, near the lower starting end of the round blade 5, there is a dough ball carrying conveyor 14 that carries the dough balls from the dividing process in the previous process.
is provided. The dough ball outlet chute 13
The excess flour that did not adhere to the surface of the dough ball A is passed through the part corresponding to the umbrella surface 4 of the dough ball A.
A large number of small holes 15 are drilled to allow it to fall upward.

The operation of the conventional umbrella-shaped rounding machine 1 having such a configuration will be described below.

As shown in FIG. 5, when a dough ball A is conveyed by the dough ball carrying conveyor 14 from the dividing step which is a pre-rounding step, this dough ball A is
It is thrown onto the umbrella surface 4 of the umbrella type rounding machine 1 and advances as the umbrella surface 4 rotates. The ball of dough A is then compressed and rotated while being sandwiched between the round blades 5, which are spirally installed from the bottom to the top of the umbrella surface 4, and is gradually formed into a spherical shape. The dough ball A formed into a spherical shape is transported by the dough ball outlet chute 13 provided at the upper end of the round blade 5.
It is now ready to be transported to the next process, the bench process.

[Problem that the invention attempts to solve]

The conventional umbrella-shaped rounding machine 1 as described above has the following problems.

As mentioned above, the purpose of the rounding process is to allow the shaping process after the next bench process to flow smoothly, to form a thin uniform film on the surface of the dough ball, to close the cut end of the dough ball, and,
The aim is to correct the disturbance of the gluten structure during division in the direction of the network structure. To achieve this goal, manual hand-cutting is the best method. However, mass production is not possible by hand, and it is not cost-effective. Therefore, when rounding is performed using the umbrella-shaped rounding machine 1, which is a type of mechanical rounding, by making the shape between the umbrella face 4 and the rounding blade 5 of the umbrella-shaped rounding machine 1 palm-shaped, the rounding machine 1 can be rounded by hand. It is possible to obtain an effect close to round eyes. Therefore, conventionally, the cross-sectional shape of the round blade 5 is made such that the angle α 1 between the inner surface of the round blade 5 and the canopy surface 4 is small near the lower starting end, and the angle α ₁ between the inner surface of the round blade 5 and the umbrella surface 4 is made smaller near the upper terminal end, as shown in FIG. In this case, as shown in FIG. 8, this is dealt with by increasing the angle α ₂ . however,
This conventional approach has the problem that it is still not possible to achieve the same effect as Temarume.

In addition, the round blades 5 of the umbrella-shaped rounding machine 1 are installed in a spiral shape from the bottom to the top of the umbrella surface 4 of the truncated cone-shaped umbrella type 3, so that the ball of dough A can pass through the round blades as described above. 5 and the umbrella surface 4 (see FIGS. 7 and 8), and while rotating itself with the rotation of the umbrella shape 3, it is guided by the round blades 5 and is inserted from below to above the umbrella surface 4. While moving to
It is rolled into a spherical shape while being compressed and rotated. On this occasion,
The distance between the umbrella surface 4 and the round blade 5 is formed so that it gradually increases slightly from the lower starting end to the upper end of the round blade 5. Therefore,
When putting the dough ball A into the gap 16 and rotating the dough ball A while lightly tightening it with the round blade 5 and rolling it into a spherical shape, if the dough balls A differ in size or weight, please Another problem was that it was impossible to close the cut and form a thin film on the surface.

Furthermore, when the diameter of the umbrella mold 3 of the umbrella rounding machine 1 is large, the dough ball A always has the same outer peripheral surface in the slight gap 17 formed at the contact point between the umbrella surface 4 and the rounding blade 5. As a result of the sliding contact, the surface of the ball of dough A was not evenly and sufficiently rounded, and the surface was damaged and became uneven.

[Means for solving problems]

This idea was made in view of the above circumstances, and the specific technical means to solve these problems is to install a rotating umbrella-shaped umbrella in a spiral shape from the bottom to the top. In the umbrella-shaped rounding machine which rolls dough by interposing a ball of dough in the gap between the round blade and the umbrella surface, a convex part is formed on the inner surface of the round blade facing the umbrella surface.

(Function) This invention adopts the above-mentioned specific technical means, so that in the rounding process performed using an umbrella-shaped rounding machine, the irregularly shaped dough balls brought in from the dividing process in the previous process are When the umbrella-shaped umbrella surface is guided by round blades installed in a spiral shape from the bottom to the top and rolled up, the convex part formed on the inner surface of the round blade prevents the Displace position. As a result, the time of contact with the umbrella surface and the rounded feathers becomes almost uniform for all surface parts of the ball of dough, and it is possible to obtain the same effect as the rounding effect of the ball of dough achieved by hand rounding.

〔Example〕

One embodiment of this invention will be described in detail below with reference to FIGS. 1 to 3. The umbrella-type rounding machine having a rounding blade according to an embodiment of this invention has basically the same structure as the umbrella-shaped rounding machine described in detail in the related art except for the rounding blade part.

As shown in FIGS. 1 and 2, on the inner surface of the umbrella-shaped rounder 1 facing the umbrella surface 4 of the umbrella-shaped 3,
A convex portion 18 is provided to protrude in the four directions of the umbrella surface. The number of the convex portions 18 is 3 in the embodiment.
Although the locations are shown, there is no limitation, and the locations may be one, two or more. In addition, this convex portion 18
may be formed by integrally molding with the round blade 5,
It may be joined to the inner surface of the round blade 5 using bolts or the like. Further, the convex portion 18 is formed such that the width in the turning direction of the round blade 5 decreases from the outer circumference to the inner circumference of the round blade 5, and a flat apex 19 is formed at the center of the convex portion 18. It is installed protrudingly.
This apex 19 is not limited to one, but two.
Two or more protrusions may be provided.

The rounding effect of the dough ball of this invention having such a structure will be explained next.

As shown in FIG. 1, an irregularly shaped dough ball A is carried in from the previous dividing step by a dough ball carrying conveyor 14. This dough ball A is put onto the umbrella surface 4 of the umbrella mold 3, is sandwiched between the round blades 5 and the umbrella surface 4, and is compressed and rotated. When the dough ball A comes into contact with the convex portion 18 formed on the inner surface of the round blade 5, the dough ball A is displaced. At this time, since the distance between the convex portion 18 and the umbrella surface 4 is narrowed, the compressive strength against the dough ball A is increased, and almost the same effect as hand kneading can be obtained. When the ball of dough A passes through this convex portion 18 and reaches the flat portion again, the space portion expands and is further displaced. In this way, each time the ball of dough A reaches the convex portion 18, a large displacement is applied to the ball of dough A.

In FIG. 1, the convex portions 18 are formed at three locations from the starting end of the round blade 5 to a point corresponding to approximately half of the total length of the round blade 5, but the present invention is not limited to this, and the convex portions 18 are formed as desired. What is necessary is to form it up to the location and point. However, if the round blade 5 is formed to the vicinity of the upper end, the round blade 5 will be carried out to the next bench process in an insufficiently finished round state, so from the protrusion 18 at the rearmost end to the upper end of the round blade 5, Consideration must be given to leaving a required predetermined length for the finished round of dough ball A. Experimentally, from the lower starting end of the round blade 5 to one-third to one-half of the total length of the round blade 5.
Formation over a range of degrees produces the best effect.

Note that the convex portion 18 formed on the inner surface of the round blade 5
The surface of the blade is coated with polytetrafluoroethylene resin, or a thin plate made of polytetrafluoroethylene resin is curved into a convex shape, and this thin plate is joined to the round blade 5 (see Fig. 3a). ),
Alternatively, it may be connected to a round blade 5 having an integrally molded convex portion with bolts or the like (see FIG. 3b). Furthermore, other materials than polytetrafluoroethylene resin may be used as long as they do not easily adhere to the dough ball.

[Effect of idea]

As is clear from the above explanation, this idea is
In an umbrella-shaped rounding machine that rounds a rotating umbrella-shaped umbrella surface by interposing a ball of dough in the gap between the round blades installed in a spiral shape from below to above and the umbrella surface, the round blades are rolled. Since the convex part is formed on the inner surface facing the umbrella surface, the irregularly shaped dough balls brought in from the dividing process in the previous process are subjected to the same effect as hand rounding, so the surface A uniform thin film is formed on the grain, the cut during the dividing process is closed neatly, and the disordered gluten structure is corrected in the mesh direction. In addition, even if the dough balls differ in size and weight, the compressive strength is increased in the convex part formed on the inner surface of the round blade, so each ball of dough can be rounded sufficiently. This allows the cut to be closed and a uniform thin film to be formed on the surface. In addition, the outer peripheral surface of the same ball of dough does not always come into sliding contact with the small gap formed at the contact point between the umbrella surface and the round blade, and is rolled up evenly, so the surface of the ball of dough is not damaged. It becomes smooth without any problems.
In addition, the convex part formed on the inner surface of the round blade allows you to achieve almost the same effect as hand-made hand round blades, so the next bench process and subsequent steps are carried out smoothly. The flavor and aroma of bread and confectionery become sufficiently excellent. Furthermore, since it is an extremely simple and inexpensive improvement of forming a convex part on the inner surface of the round blade of the conventional umbrella-type round blade, it is possible to obtain almost the same effect as the hand round blade. Nevertheless, the above effects can be obtained without increasing running costs and without changing the conventional manufacturing process.
