DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates, after mixing a coagulant to soy milk, and filled into packaging bags, and then relate production equipment of packed tofu coagulating the soymilk to seal the packing bag is there.

[0002]

2. Description of the Related Art Conventionally, as devices for producing filled tofu, the following devices (a) and (b) have been proposed.

(A) Individual packaging containers are prepared in advance, and an amount of soy milk and a predetermined amount of a coagulant corresponding to one packaging container measured by a measuring cylinder are charged into an intermediate container. The intermediate container is moved up and down by an elevating device to stir and mix in the intermediate container, and then filled into the packaging container to produce a filled tofu manufacturing device (Japanese Patent Publication No. 53-36028).
Reference).

(B) A filled tofu manufacturing apparatus in which a predetermined amount of soymilk and a coagulant are dropped and filled into a heat-resistant container supported by a conveyor, whereby the soymilk and the coagulant are stirred and solidified in the heat-resistant container. (Japanese Patent Publication No. 53-395
No. 08).

[0005]

Among the above prior arts, the method (A) cannot stably disperse a coagulant in a fine state in a soymilk matrix in a short time because stirring is performed as mixing means. If the stirring in the intermediate container is performed for a long time, the coagulation reaction of the soymilk proceeds in the intermediate container, and the injection nozzle may be clogged and the packing container may not be filled. In addition, since it is necessary to provide a measuring cylinder, an intermediate container, and an elevating device therefor, there is a problem that the device becomes complicated and large.

Further, (b) is a method in which the soymilk and the coagulant are naturally dropped into a packaging container and mixed in the packaging container. Therefore, uneven coagulation due to poor stirring occurs, and the filling tofu is reduced. There is a problem that quality is reduced.

The present invention has been made in view of the above-mentioned problems of the prior art, and the coagulation reaction of soymilk does not proceed before filling the packaging bag , and the coagulant is uniformly dispersed in the soymilk. it is an object to realize a production equipment of the packed tofu which can be distributed to.

It will be described based on examples of production equipment for filling Tofu EXAMPLES present invention with reference to the drawings.

FIG. 1 is an explanatory view of an embodiment of a filled tofu producing apparatus, and FIG. 2 is an enlarged partial sectional view showing a main part of the filled tofu producing apparatus shown in FIG.

The apparatus for producing packed tofu of this embodiment is roughly divided mixed with later laminar flow state of being merged with coagulant soybean milk in a stream, then the soy milk filling means for filling the hull Sobukuro , and a bag making sealing means for sealing said packaging bag in which the soymilk is filled with the production of packaging Sobukuro than films having a heat fusible by the vertical pillow bag-making machine.

The soymilk filling means is constructed as follows. A soymilk hopper 3 for storing soymilk and a coagulant hopper 4 for storing a coagulant are provided at the uppermost portion, and the soymilk stored in the soymilk hopper 3 flows down at a predetermined flow rate. The upper end of the introduction pipe 7 with the flow control valve 5 interposed therebetween communicates with the upper end of the introduction pipe 7, and the coagulant hopper 4 has a fixed amount supply valve 6 for allowing the coagulant stored therein to join the soymilk flowing down. The lower end of the coagulant introduction pipe 8 is communicated with the inside of the lower end of the introduction pipe 7 and the inlet side of the static mixer 12 at the junction 9. Have been.

Downstream of the junction 9, a static mixer 12, which will be described later, is communicated, and near the junction 9, a branch pipe 10 that can be opened to the atmosphere via an air release valve 11 is communicated. The outlet side of the static mixer 12 is connected to a filling nozzle 16.

Here, the fixed amount supply valve 6 and the air release valve 11 will be briefly described.

As shown in FIG. 2, the fixed amount supply valve 6

A detecting unit 6f having a rotary blade 6h integrally provided on a rotating shaft 6i for detecting the flow rate of the agent, and a setting unit 6e capable of arbitrarily setting the flow rate of the coagulating agent in advance
And the set flow rate set in the setting section 6e and the rotary blade 6
When the flow rate of the coagulant flowing down through the opening 6c detected by the detection unit 6f matches with the flow rate h, the driving unit 6d drives the ball valve 6a to close the opening 6c.

The air release valve 11 includes a spherical valve 11c,
A plurality of air escape holes 11b open to the atmosphere and a spherical valve 1
1b and a porous filter 11d interposed between the air escape hole 11b. By rotating the handle 11a to rotate the spherical valve 11c, the branch pipe 10 is opened to the atmosphere through the air escape hole 11b. It is configured so that air can be evacuated.

As shown in FIG. 2, the static mixer 12 is provided with a tubular body 12a, a diffuser 12b provided on the inlet side of the tubular body 12a, and a diffuser 12b and an outlet between the diffuser 12b and the tubular body 12a. It is composed of a spiral wing-like spiral element 12c, and has a function of reducing the flow rate of the soymilk to which a coagulant has been joined by a diffuser 12b, and then performing split mixing in a laminar flow state by the spiral element 12c. As described above, since the coagulating agent and the soymilk are not mixed by being rapidly stirred, uniform and fine dispersion can be achieved in a short time, and the coagulation reaction of the soymilk can be caused to flow without progress.

On the other hand, the bag making and sealing means is constituted as follows.

The film 19a drawn from the winding roll 19 and disposed near the upper portion of the static mixer 12 in the figure is curved into a cylindrical shape surrounding the outer peripheral surface of the tubular main body 12a of the static mixer 12, and both side edges thereof are formed. And a back seal machine 14 for heat-sealing the overlapping portion disposed below the former 13 in the drawing, and blowing the soy milk on the outer peripheral surface of the filling nozzle 16. A sizing member 15 composed of two sizing rings is provided for preventing the
The handle member 17, the horizontal seal member 18a, and the press and cutter member 18b are sequentially disposed at intervals longer than the length of the individual members.

In this embodiment, the cutter member is used.

Next, each step of the method for producing filled tofu using the apparatus for producing filled tofu of the above embodiment will be described.

The following steps described below are steps during a so-called steady operation in which filled tofu is continuously produced, and the soymilk hopper 3 is supplied to the soymilk in the soymilk tank 1 by the first pump 1a. And the coagulant in the coagulant tank 2 is supplied to the coagulant hopper 4 by the second pump 2a.

As shown in FIG. 3A, by the end of the previous cycle, the handling member 17 and the lateral seal member 1
8a and a press and cutter member 18b are all closed, only the filling nozzle insertion portion 21a between the member 17 squeezing the sizing member 15 of the packaging Sobukuro 21 and soymilk filled, packed tofu produced in the previous cycle The upper end seal portion 22 is sandwiched by the horizontal seal member 18a, and the lower end seal portion of the filled tofu 22 is horizontally sealed again in the previous cycle, and is again sandwiched by the press and cutter member 18b. Also, the flow control valve 5 is kept open. For this reason, the flow of the soymilk in the static mixer 12 and the introduction pipe 7 is stopped.

As shown in FIG. 3B, after the above process, the handling member 17 is opened, and at a predetermined timing, the fixed amount supply valve 6 is opened, and the filling nozzle insertion portion 2 is opened.
Soy milk filled in 1a followed by static mixer 1
2 and the soy milk stopped in the introduction pipe 7 is allowed to flow down,
A predetermined amount of coagulant is joined to the falling soy milk from the joining section 9 and divided and mixed in a laminar flow state while flowing down the static mixer 12 by its own weight, and then the lower end is sealed via the filling nozzle 16. The coagulant is uniformly dispersed in the soymilk in the packaging bag 21.

After the above steps, as shown in FIG. 3C, the horizontal seal member 18 a and the press and cutter member 18 b are opened, and the filled tofu 22 ′ produced in the previous cycle is cut off and placed on the belt conveyor 23. Let it fall.

After the above steps, as shown in FIGS. 3D and 3E, the packaging bag 21 and the filled tofu 22 ″, 2
2 is lowered, and as shown in FIG. 3A, the horizontal seal member 18a and the press and cutter member 18b are closed, and the upper end side of the filled tofu 22 "is heat-sealed to form a seal portion. Seal.

At this time, the film 19a pulled out from the winding roll 19 with the lowering of the packaging bag 21 is sequentially curved by the former 13 into a cylindrical shape surrounding the outer peripheral surface of the tubular main body 12a of the static mixer 12, and is axially moved. An overlapping portion is formed in the cylindrical film 2 while the overlapping portion is thermally fused by the back sealing machine 14 while moving downward.
0 is further formed, and the filling nozzle insertion portion 2 is located between the portion sandwiched by the sizing member 15 and the handling member 17.
1a is formed.

In parallel with the above steps, the filled tofu 22 dropped on the belt conveyor 23 by the above steps
Is conveyed to a boil tank 24 for sterilization and coagulation, and then to a cooling tank 25 for cooling in the cooling device 25.

By repeatedly executing the above-mentioned steps, the filled tofu 22 is continuously produced.

At the time of start-up, the winding roll 1 is kept in a state where both the flow control valve 5 and the fixed amount supply valve 6 are closed.
The film 19a is pulled out from the 9 and the former 13
Back seal machine 14, sizing member 15, handling member 17,
After passing through the horizontal sealing member 18a and the press and cutter member 18b to first produce a packaging bag filled with soymilk, the flow control valve 5 is opened, and steps similar to the above steps are sequentially executed.

Gas release is performed by opening the air release valve 11 and opening the branch pipe 10 to the atmosphere through the air escape hole 11b, thereby releasing gas such as residual air in the introduction pipe 7 to the atmosphere. However, this degassing is preferably performed at startup. In other words, when degassing is not performed at the time of startup, there is a possibility that gas such as air remaining in the introduction pipe may appear as bubbles in the filled tofu at the stage of transition to the above-described steady operation.

The above embodiment has the following effects.

(1) The coagulating agent introducing tube 8 is arranged inside the introducing tube 7, and the lower end of the introducing tube 7 and the lower end of the coagulating agent introducing tube 8 are set at substantially the same position in the flow path direction. By arranging the confluent portion of the coagulant at the inlet of the static mixer 12, the set mixing ratio is disturbed due to a slight pressure difference between the introduction pipe 7 and the coagulation agent introduction pipe 8, and the one introduction pipe is connected to the other introduction pipe. Can be prevented, and a partial coagulation reaction before being supplied to the static mixer 12 can be prevented.

(2) Air is supplied to the filling nozzle insertion portion 21a of the packaging bag by the air bleeding means before the soy milk and the coagulant are supplied to the static mixer 12 and the liquid level regulation of the filler by the sizing member 15. Since it does not exist, the generation of air bubbles in the filled tofu can be prevented.

(3) A horizontal sealing member 18a and a press and cutter member are used for manufacturing a packaging bag from a resin film having heat-sealing property by a vertical pillow bag making machine and sealing the packaging bag filled with soymilk. In step 18b, the packaging bag is once horizontally sealed, and then the horizontally sealed portion is pressed again and continuously separated and cut, whereby the packaging bag can be prevented from being damaged and the sealing failure can be prevented, and the manufacturing process can be achieved. The cycle can be shortened.

Further, the present invention can be implemented by the following modifications.

[0039] As a means for supplying the bean milk filling nozzle,
A forced supply means such as a pump can be used.

As a coagulant, GDL (glucono-
Not only delta-lactone) but also natural bitter mainly composed of calcium chloride, magnesium chloride and the like having a high coagulation reaction rate can be used. Particularly, when natural bitter is used, it is possible to produce a filled tofu having a good flavor. Can be.

[0041]

Since the present invention is configured as described above, the following effects can be obtained.

When the soymilk mixed with the coagulant is filled into the packaging bag through the static mixer, the coagulant is uniformly dispersed in the soymilk. Therefore, natural bitter having a high coagulation reaction rate is used as the coagulant. be able to. For this reason, it is possible to continuously produce packed tofu having a good taste, and to uniformly disperse the coagulant in soy milk in a short time, thereby preventing uneven coagulation and generation of bubbles.

[0043] Also, because they are to flow down by gravity beans milk and coagulant, there is no such thing as the apparatus as in the conventional art is complicated and large in size.
