DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dried food and a method for producing the same, and more particularly to a vacuum freeze-dried food such as an instant soup having a high viscosity and a method for producing the same.

[0002]

2. Description of the Related Art As is well known, various ready-to-eat foods manufactured using the technology of forming vacuum freeze-drying have been put to practical use. The above instant foods can be easily eaten by returning to the state before freeze-drying simply by applying hot water,
It is a very useful food for people living in a busy modern society.

[0003] When the instant food is reconstituted with hot water, it is preferable to spread the hot water evenly over the surface of the instant food. However, when hot water is applied to this kind of instant food, the surface thereof is immediately in contact with the hot water, but the inside cannot be touched unless the hot water penetrates through the dried food.

[0004] In particular, in the case of food having a high viscosity, the speed at which hot water permeates into the interior of the food becomes slow, and it takes much time to restore the food to its original state. Moreover, not only does it take much time to restore, but also when the inside is restored to a soft state before drying, the surface returns too much, so that there is a problem that so-called uneven return is likely to occur.

Therefore, as shown in Japanese Patent Application Laid-Open No. Sho 60-105467, a depression is formed in the bottom of a dried food by using a mold that can be punched out from the bottom, and the area in contact with the hot water is increased as much as possible. Techniques have been proposed to make this easier.

According to the above-mentioned prior art, since there is a depression at the bottom, the surface area is increased by that amount and the time required for hot water replenishment is shortened, but a large depression is formed at the bottom of the product. This is not preferable in terms of the appearance of the product. In view of the above, the present invention has an object to form a cavity inside the product without making the dent of the product large, so that the hot water can be returned more quickly.

[0006]

According to the present invention, there is provided a dried food having a depression at a bottom, wherein a cavity communicating with the depression at the bottom is formed inside the dried food, and the dried food has a bottom. A dried food product characterized in that it communicates with the depression via the internal communication passage, and the internal cavity is formed larger than the communication passage.

Another feature of the present invention is that
It is characterized in that the cross-sectional shape of a shape obtained by integrally combining the depression at the bottom, the communication path, and the internal cavity is H-shaped.

Another feature of the present invention is that a cavity communicating with a dent formed at the bottom of the dried food is formed inside the dried food, and the dent at the bottom is provided at the bottom of the dried food. An ice manufacturing process for manufacturing an internal space forming ice having a shape obtained by integrally integrating the communication passage and the internal cavity; and a drying tray in which the internal space forming ice is formed in a predetermined shape. And a food material is filled in the drying tray, and a drying step of drying the ice for forming the internal space and the food material is performed.

Another feature of the present invention is that the sectional shape of the ice for forming the internal space is H-shaped.

Another feature of the present invention is that the drying step is a vacuum freeze-drying step.

[0011]

Since the present invention has the above technical means, a surface which can be directly contacted with hot water is formed not only in the bottom recess but also inside the bottom recess without conspicuously forming the entire surface area. Becomes very large. Thereby, since the area that can be brought into contact with the hot water immediately when the hot water is applied is large, the return time is shortened and the return unevenness is less likely to occur.

[0012]

Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, an ice manufacturing process as a first manufacturing process will be described. As shown in FIG. 1, an internal space forming ice 1 having a predetermined shape is manufactured. In this embodiment, as shown in the side view of FIG. 1A, the front view of FIG. 1B, the plan view of FIG. 1C, and the perspective view of FIG. The ice 1 for forming an internal space having a substantially H-shaped cross section is formed.

After the ice 1 for forming the internal space is manufactured in the ice manufacturing process as described above, the process proceeds to the filling process. In the filling step, as shown in FIG. 2, the ice 1 for forming the internal space is stored in a drying tray 5 formed in a predetermined shape. The drying tray 5 is formed in a shape corresponding to the shape of the dried food to be manufactured. The ice 1 for forming the internal space is set at the center of the drying tray 5.

After the ice 1 for forming the internal space is stored in the drying tray 5 as described above, the raw material 6 for the dried food is filled in the drying tray 5 as shown in FIG. In this case, if the dry food material 6 is not filled so that a certain thickness is formed on the upper part of the ice 1 for forming the internal space, a strength problem occurs after drying, and the finished dry food may be damaged. So be careful.
As the dry food raw material 6, for example, various dry food raw materials such as instant soups and noodles can be considered.

When the filling process is completed as described above,
Next, the process proceeds to a drying step. In this embodiment, vacuum freeze-drying is performed as this drying step. In this manner, when vacuum freeze-drying is performed, the ice 1 for forming the internal space also sublimes together with the moisture in the dry food material 6,
The dried food 7 as shown in the sectional view of FIG. 4 can be obtained.

As is apparent from FIG. 4, the dry food 7 of the present embodiment manufactured by disposing the ice 1 for forming the internal space inside the dry food raw material 6 as described above has a depression 8 formed at the bottom thereof. And a cavity 9 is formed inside,
The recess 8 and the cavity 9 communicate with each other via a communication passage 10, and a substantially H-shaped space is formed therein.

Therefore, the dried food 7 produced by the production method of the present embodiment has a very large surface area. Can be very fast.

Further, since hot water permeates not only from the outside of the dried food 7 but also from the inside thereof, a difference in return time between the outside and the inside hardly occurs, and the occurrence of uneven return is reduced as much as possible. be able to.

In the above embodiment, an example was shown in which the sectional shape of the ice 1 for forming the internal space and the shape of the space formed inside the dried food 7 were formed in an H-shape. The shape of the ice 1 need not necessarily be H-shaped. Further, since the ice for forming the internal space is used in the above, even if the internal cavity formed at the bottom is larger, the internal cavity can be easily formed. That is, when forming a depression using a mold from the outside, an internal cavity cannot be formed, but this is made possible.

In short, a pit 8 is formed at the bottom of the dried food 7 and a cavity 9 is formed therein, and the space between the dent 8 and the cavity 9 is formed smaller than the size of the cavity 9. If the communication is made through the communication path 10 described above, the object and operation and effect of the present invention can be obtained satisfactorily.

[0021]

As described above, according to the present invention, a cavity communicating with the depression provided at the bottom of the dried food is formed inside the dried food, and the depression at the bottom and the interior cavity are formed by: Because it communicates via a communication passage smaller than the internal cavity, the hot water penetrates from both inside and outside of the dried food when returning hot water without returning the hot water to the bottom without making the bottom recess unnecessarily large Can be done. Therefore, it is possible to prevent the inconvenience that the speed at which the hot water permeates the inside of the dried food is largely different between the inside and outside of the food, and to provide a high-quality dried food without uneven return. Further, since the surface area can be further increased, it is possible to provide a dried food having a quick return time even with a drying soup having a high viscosity.

According to another feature of the present invention, a dent formed at the bottom of the dried food, a cavity formed inside the dried food, and a communication passage communicating the dent with the internal cavity are provided. In addition to producing the ice for forming the internal space having an integrally synthesized shape, the ice for forming the internal space is stored in a drying tray formed in a predetermined shape, and the food material to be dried there. And thereafter, the ice for forming the internal space and the food material are dried together, so that the hollow at the bottom and the internal cavity, and the communication path for communicating the hollow with the hollow can be easily formed, In addition to this manufacturing advantage, it is possible to easily produce a dry food product having a quick return time and no return unevenness.

According to another feature of the present invention, the drying step is performed by vacuum freeze-drying, so that the dried food in which the ice for forming the internal space is disposed can be quickly removed.
And it can be dried well.
