Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an apparatus for producing bean curd, particularly to an improvement of the soybean milk heating section thereof.

[Prior art] Yuba, which is obtained by heating soy milk and collecting the coagulated thin film that forms on the liquid surface, is widely known as a traditional food in Japan. It is also attracting attention as a health food rich in vegetable fats.

Conventionally, to produce yuba, soybeans are soaked in water, then ground and filtered to obtain soymilk, which is then poured into a heating tank and heated at a temperature of about 90°C for 10 to 15 minutes. Then, the solidified thin film formed on the liquid surface was scooped up one by one with a stick and dried.

However, this classical method for producing yuba is complicated, and it takes time to wait for a thin solidified film to form on the surface of the liquid before scooping it out one by one, and it is difficult to make it continuous or automated.

Therefore, in the past, various improvements have been made to the yuba manufacturing equipment (Japanese Patent Application Laid-Open No. 1973-
22844, JP 54-80448, JP 55-50872, JP 59-151852).

For example, Japanese Patent Application Laid-Open No. 59-151852 discloses the following yuba manufacturing apparatus.

That is, as shown in FIG. 8, soybean milk 12 is poured into the soybean milk tank 10, and a heating section 14 is installed facing the side surface of the soybean milk tank 10 rather than the bottom surface.

The heating section 14 is filled with hot water of about 90°C. Therefore, after a certain period of time, a solidified thin film 16 is formed on the surface of the soymilk 12.

Here, a cooling pipe 18 through which cold water flows is installed at the upper part of the periphery of the heating part 14 to cool the upper part of the soymilk.

As a result, the coagulated thin film 16 is not formed in the vicinity of the soybean milk tank 10, and the coagulated thin film 16 is prevented from adhering to the wall surface of the soymilk tank 10. Therefore, it has the advantage that the coagulated thin film 16 can be easily pulled up from the soybean milk tank 10, and automation and continuous production of bean curd is also expected.

[Problems to be solved by the invention] Problems of the prior art However, although such conventional yuba manufacturing equipment has a heating section that heats the entire soybean milk in the soybean milk tank, only the upper part of the soybean milk tank is heated. The structure required forced cooling, which inevitably led to a decrease in thermal efficiency.

With conventional production equipment, by uniformly heating the entire soymilk, the soymilk heating rate in the soymilk tank is improved, and convection is not caused, promoting the formation of a coagulated thin film. This is because it prevents adhesion to the tank.

In this way, the formation efficiency of the solidified thin film is improved,
Facilitating the pulling up of the coagulated thin film reduces the thermal efficiency of the heating section, while stopping cooling improves the thermal efficiency, but causes the problem that the coagulated thin film adheres to the soybean milk tank, making it difficult to pull it up.

Purpose of the invention The present invention was devised in view of the problems of the prior art, and its purpose is to produce bean curd that can maintain good thermal efficiency of the heating section and prevent the solidified thin film from adhering to the soybean milk tank. The goal is to provide equipment.

[Means for Solving the Problems] In order to achieve the above object, the yuba manufacturing apparatus according to the present invention includes a soybean milk tank and a heating section.

Then, soy milk is poured into the soy milk tank.

Further, the heating section is arranged at a predetermined distance from the peripheral edge of the bottom surface of the soybean milk tank.

[Function] Since the yuba manufacturing apparatus according to the present invention has the above-described configuration, the heating section does not heat the sides of the soybean milk tank, but only the bottom surface thereof.

Moreover, since the bottom surface of the soybean milk tank is also heated from a position a predetermined distance away from the edge thereof, the temperature of the soymilk at the periphery of the soybean milk tank does not rise significantly.

As a result, the coagulated thin film of soybean milk is not formed at the peripheral edge of the soybean milk tank, and the coagulated thin film and the soymilk tank do not adhere to each other.

On the other hand, the soy milk is heated by the heating section from a position a predetermined distance away from the peripheral edge of the soy milk tank and rises, forming a coagulated thin film on the surface of the soy milk.

Therefore, the thermal efficiency of the heating section does not decrease.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a schematic configuration of a yuba manufacturing apparatus according to an embodiment of the present invention, and parts corresponding to those in the prior art are designated by the reference numeral 100 and their explanations are omitted.

A characteristic feature of the present invention is that the heating section is located at a predetermined distance from the bottom edge of the soybean milk tank.
The heating unit 114 is arranged 100 to 120 mm away from the bottom edge of the housing 10 .

FIG. 2 shows in detail the structure of the soybean milk tank 110 and the heating section 114 from the top surface A and the side surface B according to this embodiment.

That is, a heating part 114 through which heating steam is conducted is arranged at the bottom of the soybean milk tank.

The heating section 114 has steam introduction holes 120a and 120 on both sides of the front and rear sides of the arrow in the direction of movement of the solidified thin film.
b, 120c, and 120d are arranged.

A discharge hole 1 is provided at the lower center of the heating section 114.
22 are provided.

The heating section according to this embodiment is constructed as described above, and when hot steam of about 110° C. is introduced from the steam introduction hole 120 in the direction of the arrow, each steam flows as shown by the arrows a, b, c, and d. It flows along the edge of the heating section and changes direction toward the discharge hole 122 near the center.

Therefore, in the heating section 114, the temperature at both side edges becomes high with respect to the direction in which the solidified thin film advances, and the temperature at the center becomes slightly low.

By the way, as described above, the heating unit 114 is placed a predetermined distance away from the bottom edge of the soybean milk tank 110, and the temperature of the soymilk at the periphery tends to be lower.

Therefore, if the temperature distribution of the heating section 114 is made uniform, the solidified thin film 116 will be thicker at the center and thinner at the side edges.

On the other hand, in this embodiment, since the temperature at the side edge of the heating section is high, the solidified thin film 116
Sufficient soy milk temperature can be obtained even at the side edges, and a coagulated thin film with a uniform thickness can be formed at both the center and side edges.

In this case as well, the soymilk 1 in the soymilk tank 110
12 is heated only at its lower part corresponding to the heating part 114, and the soymilk located at the side edge of the soybean milk tank is slightly affected by the heating, but is cooled at the side edge of the soybean milk tank and forms a solidified thin film. There's nothing you can do.

That is, as shown in FIG. 3, the soymilk heated by the heating section 114 rises as shown by the dotted line and forms a coagulated thin film 116, but the soymilk at the side edge of the soybean milk tank rises as shown by the dotted line on the side wall of the soybean milk tank. It is cooled down and descends.

Therefore, some liquid flow occurs between the surface of the soybean milk 112 corresponding to the edge of the heating section 114 and the side wall of the soybean milk tank 110, and the temperature does not rise, so that the solidified thin film 11
6 is not formed.

Note that depending on the shape and size of the soybean milk tank, there may be cases where no liquid flow of soymilk occurs, but the formation of the solidified thin film 116 may be prevented by the cooling effect of the side wall of the soybean milk tank.

As described above, according to the configuration of the heating section according to the present embodiment, it is possible to prevent the solidified thin film from adhering to the soybean milk tank without forcibly cooling a part of the heating section, and the thermal efficiency is increased.

Moreover, a uniform thickness can be obtained at the center and side edges of the solidified thin film.

Next, the apparatus of this embodiment for continuously manufacturing rolled Yuba of a predetermined size will be explained with reference to FIG. 1 again.

The apparatus according to this embodiment has a conveyor section 130
, a conveyance roller 132, a take-up roller 134,
It includes a cutting section 136 and a rolled yuba collecting section 138.

Here, the conveyor section 130 includes a conveyor belt 140, a drive pulley 144 interlocked with a motor 142, a tension pulley 146 that applies appropriate tension to the conveyor belt 140, and four pulleys 148, 150, 152, and 154. , becomes more. Then, the coagulated thin film 116 formed on the surface of the soymilk 112 heated by the heating unit 114 is continuously pulled up by the conveyor belt 140.

Further, a conveyance roller 132 is located between the pulleys 148 and 154, and the conveyance roller 132 is rotated by a drive motor 156 in the same direction as the conveyor belt 140, that is, in the direction of the arrow in the figure.

A take-up roller 134 is provided adjacent to the conveyance roller 132, and the take-up roller 134 is rotated in the same direction as the conveyance roller 132 by a drive motor 158.

The cutting section 136 is located above the winding roller 134, and its cutting blade is located so as to be able to come into pressure contact with the conveyance roller 132.

The winding yuba collecting section 138 includes the winding roller 13
4 and its drive motor 158, a piston cylinder 162 that rotatably supports the rotating frame 160, and a receiver 166 that receives the cut rolled Yuba 164. Then, by storing the piston rod 162a of the piston cylinder 162 in the cylinder, the rotation frame 160 rotates downward about the rotation center of the conveyance roller 132, and is placed on the upper part of the adjacent portion of the conveyance roller 132 and the take-up roller 134. The placed rolled Yuba is stored in the receiver 166.

Note that a washer 168 is provided below the conveyor belt 140, and the conveyor belt 140 is washed with water if necessary.

Further, just before the coagulated thin film 116 pulled up from the soybean milk tank 110 is placed on the conveyor belt 140, a scraping plate 1 is brought into contact with the lower surface of the coagulated thin film.
70 are provided. This scraping plate scrapes off the soymilk below the coagulated thin film.

The continuous manufacturing apparatus for rolled yuba according to this embodiment is as follows:
The structure is roughly as described above, and then Figures 4 to 7
The operation will be explained with reference to the drawings.

First, in FIG. 4, the ends of the coagulated thin film 116 formed in the soybean milk tank 110 are pulled up and placed on the conveyor belt 140.

The conveyor belt 140 has a drive pulley 144
The solidified thin film 11 is moving in the direction of the arrow due to
6 will be conveyed on the conveyor belt in the direction of the conveyance roller 132.

Next, as shown in FIG. 5, the solidified thin film 116 on the conveyor belt 140
When reaching the upper part of , the coagulated thin film 116 and the conveyor belt 140 are separated, the coagulated thin film 116 is directly placed on the conveying roller 132, and the conveyor belt 140 moves in the direction of the pulley 148.

Here, at the beginning of collecting the coagulated thin film 116, the coagulated thin film 116 may move toward the pulley 148 while remaining attached to the conveyor belt 140;
In this case, pulley 148 and drive pulley 144
Since the peeling roller 172 disposed between the two rotates in the opposite direction to the conveyor belt, the coagulated thin film 1
16 is peeled off from the conveyor belt 140 and securely placed on the conveyance roller 132.

Next, as shown in FIG. 6, the solidified thin film 11
6 reaches the take-up roller 134, since the take-up roller 134 is rotating in the same direction as the conveyance roller 132, the coagulated thin film 116 is transferred to the conveyance roller 1.
I can be older than 32.

Then, the coagulated thin film 116 is wound up near the rollers 132 and 134, and a rolled yuba 164 is formed.

When the rolled Yuba 164 reaches a predetermined size, the cutting section 136 is activated and the coagulated thin film 116 on the conveying roller 132 is cut.

Here, in this embodiment, the rolled yuba 164
The size is controlled by the winding time.

When the rolled yuba 164 of a predetermined size is formed on both rollers 132 and 134 as described above, the seventh

That is, when the piston rod 162a of the piston cylinder 162 is housed in the cylinder, the rotation frame 160 supported by the piston cylinder 162 rotates downward.

Then, the rolled Yuba, which was located above the adjacent portion of both rollers 132 and 134, rolls down over the winding roller 134 as shown by the dotted line in the figure, and is accommodated in the receiving portion 166.

In this way, the rolled yuba is automatically manufactured.

Note that when the rolled Yuba 164 is accommodated in the receiving portion 166, the piston cylinder 162 returns again, and the rotating frame 160 is in the state shown in FIG. 6.

Then, by the same action as described above, both rollers 13
The solidified thin film 116 is wound up on the upper part of the proximal portion of 2,134, and continuous production of rolled Yuba is performed.

In this embodiment, the take-up yuba collecting unit has a structure in which the take-up roller is installed on the rotation frame, but the structure is not limited to this. For example, the conveying roller and the take-up roller are separated, and the It is also suitable to have a structure in which the rolled Yuba is dropped and collected.
