2. Description of the Related Art In general, seasoned fried tofu is widely sold as a skin for Inari sushi and as an ingredient for fox and udon. In the production of these deep-fried foods, the dough is immersed in a high-temperature oil layer together with the mold, and the oil layer is passed through for a predetermined time to perform frying. Of the deep-fried fried foods, those that are intended for Inari sushi are subjected to a process of injecting air into the bag to form a bag for forming sushi rice inside. The work to make this inside a bag is
In the olden days, the frying surface was smoothed with Surikogi or the like and separated, but in recent years, the tofu substance inside the frying is separated by injecting air with an injection needle to form a bag.

[0003]

However, in the work of injecting air into the frying pan, the air pouring needle has been conventionally inserted from the side of the frying pan, so that the frying pan is easily damaged. This is because the side of the frying is likely to receive heat during frying, so the side of the frying is hardened and brittle immediately after frying, and may be broken or cracked around the insertion part by the insertion of the air injection needle. This is because. In addition, when fried such as this,
When sushi rice is packed, it breaks from there and loses its value as a product. The present invention has been made to solve such conventional problems, and the purpose thereof is to insert an air injection needle from the soft plane or bottom portion of the frying after frying to remove the frying scratches. An object of the present invention is to provide a method and a device for manufacturing a deep-fried food which prevents the separation and separates it into a bag shape.

[0004]

As a means for achieving the above object, in the method for producing deep-fried food according to claim 1 of the present invention, an air injection needle is inserted into the plane or the bottom surface of the deep-fried food to put the oil inside the deep-fried food. A method was used in which air was injected to inflate the inside and separate it into a bag shape.

According to another aspect of the present invention, there is provided a deep frying production apparatus having a conveying means for conveying the deep frying after frying and an air injecting means for injecting air into the deep frying that has been conveyed. The fried food was transported to a predetermined position by means, and an air injection needle was inserted into the plane or bottom of the fried food that was transported to inflate the fried food and separate it into a bag shape.

According to a third aspect of the present invention, there is provided a holding device for suppressing the expansion of the deep-fried food when the deep-fried food is formed into a bag shape.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. When frying with a fryer, the heat is concentrated on the sides and the sides are hard just after frying. Then, when the air injection needle is inserted into the hard side surface, the periphery of the insertion portion collapses and a large hole is formed. Therefore, in the present invention, the air injection needle is inserted into a relatively soft flat surface or bottom surface (wide surface). Hereinafter, a method for manufacturing deep-fried food according to the first embodiment will be described with reference to FIG. After frying, the fried food 1 is placed on a conveying means such as a conveyor, sequentially conveyed, and sent to the air injecting means. Then, the air injection needle 2 is inserted, air is injected into the fryer 1, and the inside is separated into a bag shape.

When the oil frying is transferred to the air pouring place, the air injecting means is activated and the air injecting needle 2 advances toward the oil frying 1. Then, the tip of the needle is inserted into the deep fryer (Fig. 1 (a)). The deep-fried food has a thickness of about 1 cm to 2 cm and a width of about several cm in length and width to about several tens of cm. At the time of insertion, the needle is inserted toward the wide surface (flat surface) of the fried food. Since the frying plane is relatively soft, the needle can be inserted smoothly and the outer skin of the frying is not damaged. In the present embodiment, the needle is inserted perpendicularly to the frying surface. After the air injection needle 2 is inserted, air is jetted from the tip of the needle to separate the tofu substance in the deep-fried oil and form a bag. Figure 1 for air injection means
As shown in (b), a plate-like member 3 (holding means) that holds down the bulge between the plane and bottom of the frying pan is installed. At the time of injecting air, the pressing means regulates the expansion of the frying oil to prevent it from expanding faster and more than necessary, so that the air is evenly distributed inside the frying oil without damaging the skin. The holding means is a plate-like member 3 having a constant weight, and is configured to hold down the expansion of the frying by gravity. Further, as the pressing means, in addition to the suppression by gravity, a frame that is slightly larger than the outer shape of the frying oil may be used to restrict the expansion width.

Next, FIG. 2 is an explanatory view of a method for producing deep-fried food according to the second embodiment. Although the needle is inserted perpendicularly to the surface of the fried food in the first embodiment, the method of manufacturing the fried food of the second embodiment is a method of inserting the air injection needle into the fried food at an angle. . Since the pressing means is positioned so as to press the central portion of the frying pan, the pressing means is obliquely inserted into the plane of the frying pan which is out of the central portion (Fig. 2).
(C)). At the time of insertion, slide the needle from the outer side of the upper part of the deep-fried food to the inner side and insert it. By inserting the needle at a position deviated from the central portion, the needle does not become a hindrance to the inflation when injecting air and can be inflated smoothly into a bag shape. In addition, by inserting diagonally, the frying can be smoothly inserted without being squeezed at the time of insertion (Fig. 2 (d)). The function and effect are similar to those of the first embodiment.

FIG. 3 is a schematic diagram of an apparatus for producing deep-fried food according to the third embodiment. The frying oil manufacturing apparatus according to the third embodiment mainly includes a conveyor 5 that conveys the frying oil 1, an air injection unit 6 that is arranged in the conveyor passage, and a holding unit that restricts expansion of the frying oil 1. The holding means is a plate-shaped member 7 having a certain weight, is installed above the fryer so as to be vertically movable, and is configured to suppress the expansion of the frying by gravity. The method of installing the plate-shaped member is arbitrary, and the plate-shaped member is installed movably so as to be able to move up and down as the frying is expanded. The conveyor 5 is a device for carrying the fried food 1 on a flat surface and carrying it, but in addition to a structure for carrying it on a belt and carrying it, it may have any structure such as a structure for carrying it on a formwork, and the fried food is sequentially fed to the air injection means. Any device can be applied as long as it has a function of transferring Immediately below the air injection means 6, a plate-like member 7 that restricts the expansion of the fryer 1 is installed, and a hole 8 through which the air injection needle 2 passes is formed in the plate-like member 7. The fryer transferred by the conveying means enters under the plate-shaped member 7, the air injection needle 2 descends from the upper portion, passes through the hole 8 and is inserted into the fryer 1. After the insertion, air is injected from the air injection needle 2 and the inside of the frying is separated into a bag shape. At this time, the weight of the plate-like member 7 regulates the expansion of the frying to prevent it from expanding faster and more than necessary, so that the air can be evenly distributed inside the frying without damaging the skin, and it is ensured. Separate the deep-fried tofu into bags.

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to this embodiment, and design changes and the like may be made without departing from the scope of the invention. Even if it exists, it is included in the present invention. For example, in the above-described embodiment, the plate-shaped members 3 and 7 have been described as the pressing means. However, the pressing means has a configuration in which the expansion of the frying is restricted during the air injection and the air is spread inside the frying. The present invention can be applied if any, and even a configuration in which only the central portion of deep-fried food is pressed is included in the present invention.

[0012]

As described above, in the method for producing frying according to claim 1 of the present invention, an air injection needle is inserted into the plane or bottom of the frying after frying to inject air into the frying, Since the method is to inflate the inside and separate it into a bag shape, the needle can be smoothly inserted without damaging the fried food. Conventionally, since the air injection needle is inserted from the side of the frying, the frying is easily scratched, and when defective products are generated in the manufacturing process, the present invention can reduce the occurrence of defective products and improve the yield. it can.

According to the second aspect of the present invention, there is provided a deep frying production apparatus having a conveying means for conveying the deep frying after frying and an air injecting means for injecting air into the conveyed deep frying. The fried food is transported to the specified position by means, and the air injection needle is inserted into the plane or bottom of the fried food, and the inside of the fried food is inflated and separated into a bag shape, so that the fried food can be smoothly moved without damaging the needle.
