Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing tofu packaged products.

(Prior art) To date, the only tofu package products that exist are those in which tofu is stored in a simple cubic plastic container and the top lid is sealed. It was obtained by heat treatment. In other words, there was no one that included drips.

Therefore, when serving the food with a meal, the user has to take the trouble of separately preparing the drippings.

This can be said to be due to the fact that the technology for manufacturing tofu pack products that also includes drippings has not been developed.

Therefore, the present applicant proposed the following prior invention (Japanese Patent Application No. 125518/1983).

That is, a pack container body having a tofu storage part and a drip storage part with an opening on the top surface is prepared, soy milk is poured into the tofu storage part and dripping is put into the drip storage part, each opening is sealed, and this is A tofu package product is obtained by heat treatment.

The invention of the earlier application will be specifically explained based on illustrative drawings. The invention of the earlier application uses a pack container body 1 as shown in enlarged form in FIGS. 5 and 6. This pack container body 1 has a deep bowl-shaped drip storage section 2 formed in its center, and a ring-shaped tofu storage section 3 is formed around the drip storage section 2.

The outer circumferential edge of the pack container body 1 also serves as the outer circumferential edge 3a on the outside of the tofu storage section 3, and this outer circumferential edge is bent downward on the inside to form a bottom surface of the tofu storage section 3. 3a, and is bent upward again from the inner end of the bottom surface 3a of the tofu storage section 3, so that its top edge becomes the top edge 2 of the sagging storage section 2.
b and the inner peripheral edge of the tofu storage section 3,
Furthermore, it is curved downward from the top edge inward to form the bottom surface 2a of the hanging storage section 2.

Further, the top edge 2b of the hanging storage section 2 and the outer peripheral edge 3b of the tofu storage section 3 are set at the same height,
On the other hand, the bottom surface 2a of the drip storage section 2 is set to a higher height than the bottom surface 3a of the tofu storage section 3, and an additive storage section 4 for condiments and the like is formed below the drip storage section 2a. .

Figures 4 to 4 show a flowchart of the invention of the prior application using the pack container body 1 described above.

First, a pack container body 1 as shown in A is fed by a container feeder to a position where a filling dripping feeder exists, and dripping A is poured from the filling dripping feeder into the dripping storage section 2 of the pack container body 1. After that, open the opening 2 of the drip storage section 2.
A sealing material 21 is pasted on c to create the state shown in c. Next, the pack container body 1 with the sealing material 21 stretched thereon is sent to a position where a soybean milk filling machine exists, and here the soybean milk b is fully filled into the tofu storage section 3. When it is filled to the brim in this way, bubbles b' bulge out on the surface of the soymilk b (see Figure 2). Then, the bubbles b' are removed using a bubble remover (not shown), and then a sealing material 31 is stretched over the entire upper surface of the pack container body 1. In other words, the sealing material 31 is applied to the opening 3c of the tofu storage section 3 (see Figure F).

It is preferable that the sealing material 21 and the sealing material 31 are both easy to open and have a trimming specification with a knob.

In this way, the pack container body 1 filled with dripping A and soymilk b is subjected to a heat treatment, that is, it is cooled after heating, and as a result, the protein coagulates and soymilk b turns into tofu B.

The pack container body 1 pulled out from the cooling tank
Adhering moisture is removed by air blowing,
After that, the automatic reversing machine turns it upside down, and the condiment dispenser puts the condiment C into the condiment storage section 4. Finally, the sealing material 4 is placed on the bottom of the pack container body 1.
1 is stretched to obtain a tofu paste product with drippings and seasonings.

Thereafter, the above product is packed in boxes and transported to the distribution market, and eventually reaches homes and restaurants. At each home and restaurant, the sealant 41 is peeled off to take out the condiment C, and the sealant is removed from the pack container body 1. 21,
31 is peeled off to expose the drippings A and tofu B and serve as food.

Therefore, according to the invention of the prior application, it is possible to easily obtain a tofu pack product with dripping, which has been a problem in the past, through a series of processes, and it is possible to provide a product with commercial value to the distribution market, and to make it possible for consumers to avoid dripping. You will be freed from the hassle of having to prepare everything.

(Problems to be Solved by the Invention) However, the above invention of the prior application still has some shortcomings. In other words, after filling the soymilk b, a step of removing bubbles b' present on the surface of the soymilk b must be provided, and
Two sealing materials 21 and 3 are placed on the surface of the pack container body 1.
1 is pasted, and during manufacturing, two types of sealants 21 and 31 must be prepared on the front side, and the purchaser also has to peel off the two sealants 21 and 31 on the front side. There is the annoyance of not being able to do so.

(Means for Solving the Problems) Therefore, the present invention provides a pack container body having a tofu storage part with an opening on the top surface and a drip storage part, and stores soybean milk in the tofu storage part and drips in the drip storage part. In the method for manufacturing tofu pack products, in which each opening is sealed after filling each opening and heat-treated to obtain a tofu pack product, the sealing material is applied to a piece of sealing material that is large enough to span the tofu storage section and the drip storage section. First, after filling the drip storage section with drippings, the sealing material is fixed only to the opening of the drip storage section, and the unfixed part of the sealing material is raised up to form the tofu storage section. is filled with soy milk, and then the tapered wall surface is applied to the rising portion of the sealing material to gradually bring down the rising portion, thereby fixing the sealing material to the opening of the tofu storage section.

(Function) According to the method of the present invention, the openings of the drip storage section and the tofu storage section can be sealed with one sheet of sealing material. Then, when the tapered wall surface hits the rising part of the sealing material and the rising part gradually falls down,
The bubbles existing in a raised shape on the upper surface of the tofu storage section are driven down, and as a result, the sealing material covers the opening and removes the bubbles at the same time. Furthermore, the purchasing user can peel off one sheet of sealing material to expose the tofu storage section and the drip storage section at the same time.

(Example) Hereinafter, the present invention will be described in detail based on illustrative drawings. 1 to 3 are flowcharts showing one embodiment of the present invention, FIG. 2 is a perspective view illustrating how to bring down the rising portion of the sealing material, and FIG. 3 is a front view showing a state in which bubbles are removed.

The method of the present invention is different from the earlier invention in the fixing process of the sealing material, and after filling the drippings and soy milk and sealing these storage areas, Follow the process.

Specifically, after filling the drip storage section 2 with the drip A (FIG. 1), the opening 2c of the drip storage section 2 is filled with the drip A (FIG. 1).
and 1 large enough to cover the opening 3c of the tofu storage section 3.
A sheet of sealing material 51 is arranged on the upper surface of the pack container body 1, and a heater 6a is approached from above to a position facing the top edge 2a, and the sealing material 51 is fixed only to the top edge 2a portion by heat fusion or the like. Figure 1).

Next, grasp both ends of the sealing material 51 by vacuum suction or the like, and raise both ends of the sealing material 51 (this raised part is referred to as "rising part 51").
It is called "a". ) to expose the opening 3c of the tofu storage section 3, and fill the tofu storage section 3 with soymilk b (Fig. 1).

Subsequently, the rising portion 51a is aligned along the upper surface of the pack container body 1 using the tapered wall surface 7a. In other words, the second
A triangular plate 7 as shown in the figure is arranged, and the rising portion 51a is gradually laid down on the tapered wall surface 7a of the triangular plate 7. And in this process, tofu storage section 3
Bubbles b' existing in the opening 3c in a raised shape are driven down to the outside of the pack container body 1 by the sealing material 51, as shown in FIG.

After the bubbles b' are removed and the sealing material 51 covers the entire top surface of the pack container body 1, the sealing material 51 is fixed to the outer peripheral edge 3a using the heater 6b (see FIG. 1). ). The subsequent treatment step is heat treatment, similar to the earlier invention.
Then, a condiment filling process is optionally performed.

According to experiments conducted by the inventors, in FIG. 1, when filling the dripping storage section 2 with the dripping A, it is advisable to fill the tofu storage section 3 with soymilk to about 85 to 90% at the same time. This makes it easier to remove air bubbles such as froth existing in soymilk (which will naturally come out over time) by the time of final filling of soymilk b in Figure 1, and also to increase the amount of soymilk filled at the final filling time. This makes it possible to reduce air bubbles contained in soymilk as much as possible.

(Effects of the Invention) As explained above, according to the present invention, only one sheet of sealing material is required to cover the surface of the pack container body, and bubbles are removed in the process of aligning the sealing material along the surface of the pack container body. As a result, the manufacturing process of pack products can be simplified. On the other hand, for the purchasing user, there is the convenience of being ready to eat immediately by peeling off one sheet of sealing material.
