Description

  The present invention relates to a method for producing sushi, particularly frozen nigiri sushi obtained by freezing nigiri sushi.

There are many opportunities to eat nigiri sushi with high taste (strong), but on the other hand, there are few opportunities to provide it at home.
Among sushi, in particular, nigiri sushi is said to be delicious right after grabbing sushi seeds on top of cooked rice that those skilled in the art call shari-tama, and there are even stores that do not have table seats only. In this regard, the taste of home delivery sushi falls.
On the other hand, nigiri sushi is difficult to cook and serve at home because it requires technology to dissect fish, sashimi from fish fillets to sushi, and technology to grip rice grains. There are few opportunities for nigiri sushi to be cooked and served at home.
In order to solve this, conventionally, nigiri sushi with a combination of shari balls and sushi seeds frozen and provided at home is known, and when a known frozen nigiri sushi is thawed In order not to heat the sushi seeds, rice and sushi seeds were put in a special container (see Patent Document 1).
In addition, paying attention to the difference in the degree of microwave heating depending on the moisture content, when placing multiple nigiri sushi in a container, place congers and eggs around the container where the degree of microwave heating increases. The structure which arrange | positions a salmon and a sweet shrimp near the center is well-known (refer patent document 2).
JP 2004-136975 A Japanese Patent Laid-Open No. 10-290673

All of the above known examples are frozen while the sushi seeds are placed on the rice that the nigiri sushi artisans call a shari-dama, so that the sushi seeds and the rice do not freeze at the same time, and the sushi seed drips into the rice. There is a problem that there is.
In addition, microwave cookers (microwave ovens) have different sizes and microwave strengths, and the frozen nigiri sushi to be thawed is also thawed according to the size and shape of the rice. There is a problem that the time is different and it is not easy to thaw, and as a result, the taste after thawing is reduced.
Among the known examples, the former has a problem that it is expensive because the container is provided with a microwave blocking film.
Of the known examples, the latter is heated for several minutes in an electronic cooking machine, and then left to stand for natural thawing, so that not only a delicate thawing technique is required, but the thawing time is long. There are challenges.
The present invention has been devised so that cheap, delicious and easy-to-use nigiri sushi can be easily thawed and improved in taste without failure at home.

In the present invention, a lower film sheet 3 of a film 2 having a predetermined size is placed on the upper surface of a stainless steel transport tray 1, and a ridge, ridge, squid, ridge, A plurality of sushi seeds 5 used for nigiri sushi 4 such as scallops, shrimp, conger, etc. are placed, and the lower film sheet 3 is transported along with the transport tray 1 and the sushi seed 5 is frozen by a refrigerator 12 and frozen. The upper film sheet 16 of the film 2 is overlapped on the upper surface of the lower film sheet 3 on which the sushi seed 5 is placed and degassed, and the lower film sheet 3 and the upper film sheet 16 are welded to vacuum-pack the sushi seed 5 At the same time, a frozen nigiri sushi production method is provided in which salmon-shaped frozen shari balls 25 corresponding to the number of sushi seeds 5 are packed separately from sushi seeds 5 by a warp 26.
In the present invention, each sushi seed 5 frozen by the freezer 12 is separately prepared on the upper surface of the transport tray 1 and laid on the lower packaging sheet 3 for finishing packaging in accordance with the shape of each sushi seed 5. The finished packaging lower film sheet 3 is set on the vacuum packaging machine 9 together with the transport tray 1 and placed on the vacuum packaging machine 9 with the frozen sushi seed 5 placed thereon. The upper film sheet 16 of the film 2 is superposed on the upper surface of the film 2 and degassed, and the lower film sheet 3 and the upper film sheet 16 are welded to produce a method for producing frozen nigiri sushi in which the sushi seed 5 is vacuum packaged. is there.
In the present invention, the ball 25 is placed on the upper surface of the film sheet 24 placed on the upper surface of the transport tray 1, the film sheet 24 is transported together with the transport tray 1 and frozen by the refrigerator 12, The frozen shari balls 25 are a method for producing frozen nigiri sushi packaged with a warp 26 made of paper or wood.
The present invention is a method for producing frozen nigiri sushi, in which the sushi seed 5 is preliminarily cut into a size corresponding to one nigiri sushi 4 and packaged by the film 2.
In the present invention, the film 2 forms a sushi seed while forming a close contact portion 20 in which the lower film sheet 3 and the upper film sheet 16 directly and vertically contact each other at predetermined positions around the plurality of sushi seeds 5. 5 is a method for producing frozen nigiri sushi by vacuum packaging.
The present invention is a method for producing frozen nigiri sushi in which the shari balls 25 are heated and thawed together with a wood cooking machine 26 and the sushi seed 5 is forcibly thawed with running water at a predetermined temperature from the outside of the film 2. Is.

The present invention is a nigiri sushi 4 in which sushi seeds 5 such as salmon, sea bream, squid, sea bream, scallops, shrimp, conger eel and egg are placed on the top surface of a shari ball 25 formed of rice bowl shaped rice. Is frozen and sandwiched between a lower film sheet 3 and an upper film sheet 16 made of a synthetic resin such as polyethylene resin and vacuum-packed, and the shaving balls 25 are frozen and wrapped with a tree 26 It is sushi.
In the present invention, the sushi seed 5 is a frozen nigiri sushi that is placed on the upper surface of the lower film sheet 3 in a state where the type and number of the sushi seeds can be distinguished one by one and frozen and packaged.
In the present invention, a plurality of the sushi seeds 5 are placed on the upper surface of the lower film sheet 3, and the lower film sheet 3 and the upper film sheet 16 are directly moved up and down around each placed sushi seed 5. Frozen nigiri sushi is formed by forming close contact portions 20 that are in close contact with each other.
In the present invention, the lower film sheet 3 is previously formed with a cell 7 corresponding to the size of the sushi seed 5 of the size of the portion, or the cell 7 is displayed below the lower film sheet 3. The frozen nigiri sushi is constructed so that the placing scale 8 can be placed and the placing work can be performed.

In the invention of claim 1, since the sushi seed 5 can be thawed with running water, there is no failure in thawing, and the shari balls 25 can be thawed and cooked with a heating cooker, so that the nigiri sushi 4 can be provided quickly at home.
In invention of Claim 2, since each sushi seed | species 5 is mounted according to a shape on the lower film sheet 3 prepared separately from the film used when it freezes, when lowering the upper film sheet 16, There is no adhesion of frost to the film sheet 3, and welding of the lower film sheet 3 and the upper film sheet 16 can be ensured.
In the invention of claim 3, the sharp ball 25 is once placed on the upper surface of the film sheet 24 placed on the upper surface of the transport tray 1, so that the freezing time can be shortened and the taste when thawed is improved, Further, since the frozen ball 25 is packaged by the warp 26, the packing operation and the thawing operation of the ball 25 can be facilitated.
In the invention of claim 4, since it has already been cut into one sushi seed 5, it does not require the labor and skill of making sashimi, and thawing of sushi seed 5 can be easily and easily performed, as if it was held by a craftsman Nigiri Sushi 4 can be provided to the home.
In the invention of claim 5, since the sushi seeds 5 packaged by the film 2 are independent of each other, the thawing can be further facilitated to prevent failure, and the sushi seeds 5 can be easily taken out from the film 2. Nigiri Sushi 4 can be cooked easily.
In the invention of claim 6, the sushi seed 5 is thawed with running water, so that the thawing is easy, and the shari balls 25 can be heated as well as thawed with a heating cooker. Each of 25 can be made into the most suitable temperature difference nigiri sushi 4 and the taste can be improved.

  The method of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a transfer tray, which is formed of a stainless steel thin plate and has a predetermined size. On the upper surface of the transport tray 1, the lower film sheet 3 out of the two films 2 is placed by the lower film sheet 3 and an upper film sheet 16 described later. Film 2 is a roll of synthetic resin such as polyethylene resin, cut into a sheet and does not penetrate oils, fats, alcoholic beverages, water, etc. Shaped to fit.

  On the upper surface of the lower film sheet 3 on the transport tray 1, sushi seeds 5 of frozen nigiri sushi 4 such as salmon, salmon, squid, salmon, scallop, shrimp, conger, etc. are placed. Each sushi seed 5 is preliminarily cut into a predetermined size for use in one nigiri sushi 4, and each sushi seed 5 is placed on the lower film sheet 3 one by one.

  In addition, kohada, conger, etc. are formed on sushi seeds 5 that have been pretreated such as “vinegared” and “boiled” in advance, and the sushi seeds 5 that have been pretreated are placed on the upper surface of the lower film sheet 3. Put.

  In this case, if each sushi seed 5 is placed so as not to overlap each other except for a part of the periphery, it is possible to suppress the occurrence of freezing unevenness and thawing unevenness, which is preferable.

  In addition, the lower film sheet 3 is previously formed with a cell 7 corresponding to the size of the sushi seed 5 of a size, or a scale for placing the cell 7 on the transport tray 1. 8 may be placed to perform the placing work, which is preferable because the placing work is facilitated.

  In addition, if the size of one sushi seed 5 (Sakaime 7) is set to a size corresponding to the size of the mouth of various people, such as for elderly people, for children, for general use, etc., the purchasing layer can be expanded, Is preferred.

  Thus, when placing the sushi seeds 5 on the upper surface of the lower film sheet 3, about 10 sushi seeds 5 such as salmon, squid, shrimp, conger, etc. are placed in a single serving. Alternatively, as many as ten of a single kind of salmon, squid, shrimp, conger, etc. may be placed, and this makes it easier for consumers to select products.

  Thus, when the size of the lower film sheet 3 is set so that several sushi seeds 5 are placed at a time, about 10 sushi seeds 5 are served on a single lower film sheet 3. When the film 2 is cut after vacuum packaging by a vacuum packaging machine 9 to be described later, a large number of sets of sushi seeds are placed with a predetermined large gap around each group. The seed 5 can be packaged, and the efficiency of the packaging operation is improved, which is preferable.

  The transfer tray 1 on which the sushi seed 5 is placed is loaded into the carriage 11 and is transported to the refrigerator 12 by the carriage 11, and the lower film sheet 3 is supplied to the refrigerator 12 together with the transfer tray 1. The sushi seed 5 on the sheet 3 is frozen. The refrigerator 12 is a known one, and a cooling blower is provided above the conveyor belt to freeze the sushi seed 5 during conveyance.

  Then, the lower film sheet 3 on which the frozen sushi seed 5 is placed is placed on the table 15 of the vacuum packaging machine 9 together with the transport tray 1, covered with the upper film sheet 16 of the film 2, and then deaerated. Then, the film 2 around the sushi seed 5 group is instantaneously heated to bring the lower film sheet 3 and the upper film sheet 16 into close contact.

That is, between the frozen sushi seeds 5, the lower film sheet 3 and the upper film sheet 16 are in close contact with each other, and the surrounding sushi seeds 5 group are heated and welded. Adhering portions 20 are formed around and around each sushi seed 5 so that the lower film sheet 3 and the upper film sheet 16 directly and vertically contact each other.
Accordingly, as described above, the close contact portion 20 is generated by placing the sushi seeds 5 without overlapping, and as a cutting allowance for separating the film 2 at the shipping stage for each of the five groups of sushi seeds. (FIGS. 3 and 10).

  In this case, although not shown in the figure, a lower film sheet 3 for finishing packaging different from that used when the sushi seed 5 is frozen by passing through the refrigerator 12 is laid on the upper surface of the transport tray 1, and this finish is performed. On the upper surface of the lower film sheet 3 for packaging, each sushi seed 5 such as salmon, salmon, squid, salmon, scallop, shrimp, conger is placed with a predetermined gap according to its shape, as described above. Thus, when the upper film sheet 16 is covered with the vacuum packaging machine 9, degassed and welded, and the lower film sheet 3 and the upper film sheet 16 are brought into close contact with each other, frost adheres to the lower film sheet 3. It can be welded in a state where it is not, and can be surely vacuum-packed, which is preferable.

  Moreover, until the freezing process by the freezer 12, the same sushi seed 5 is placed on the lower film sheet 3 and then the transfer process is performed. Although it increases, since it can work continuously from the cutting process which makes a fish body or a fillet (fence) to sushi seed 5, and the freezing process, the work efficiency of the whole work can also be improved.

  Further, since the frozen sushi seed 5 is placed on the upper surface of the lower film sheet 3 for finishing packaging, not only the placing work is facilitated but also beautifully arranged.

  Thus, the shari balls 25 of the nigiri sushi 4 are frozen in the same manner as the sushi seed 5. Shari balls 25 are rice of nigiri sushi 4 and are formed in a bowl shape so that the sushi seed 5 can be placed on the top surface.

  The method for producing the shari balls 25 is arbitrary, but the rice prepared by manual cooking or cooking is mixed with a predetermined seasoning such as vinegar, and the prepared rice is manually or shaved. A ball forming robot (FIG. 19) or the like, which is previously formed by a device called by those skilled in the art, and the formed shaving balls 25 are placed on the upper surface of the film sheet 24 laid on the upper surface of the transfer tray 1. Are transported together with the transfer tray 1 and frozen by the refrigerator 12.

The frozen shari balls 25 are wrapped and placed on a warp 26 made of paper or wood, equivalent to about 10 servings of sushi seeds 5, and the shaving balls 25 and film 2 of the warp 26 are placed. As a set, the sushi seed 5 is stored in a cosmetic box 28 for transport and sold and distributed (FIG. 15).
29 is a sink faucet, 30 is a microwave cooking machine (microwave oven).

(Operation of Example)
A lower film sheet 3 of a film 2 of a predetermined size is placed on the upper surface of the transport tray 1, and grips such as salmon, salmon, squid, salmon, scallops, shrimp, conger, etc. are placed on the upper surface of the lower film sheet 3. Place sushi seed 5 of sushi 4.

  In this case, the lower film sheet 3 is previously formed with a cell 7 corresponding to the size of the sushi seed 5 of the size of the portion, or a scale for placing the cell 7 on the transport tray 1. Since the placing work is performed by placing 8, the placing work of the sushi seed 5 can be facilitated when the sushi seed 5 is frozen and packed, and the overall workability is improved.

  Thus, the transport tray 1 on which the sushi seed 5 is placed is directly carried into the cart 11 and is transported to the refrigerator 12 by the cart 11, and the lower film sheet 3 together with the transport tray 1 is placed on the transport belt of the refrigerator 12. , The sushi seed 5 on the lower film sheet 3 is frozen by receiving cold air during conveyance.

  Next, the lower film sheet 3 on which the frozen sushi seed 5 is placed is placed on the base 15 of the vacuum packaging machine 9 together with the transfer tray 1, and the lower film sheet 3 is covered with the upper film sheet 16, By degassing and instantaneously heating the lower film sheet 3 and the upper film sheet 16 around the portion where there is no sushi seed 5, the lower film sheet 3 and the upper film sheet 16 are brought into close contact with each other. The sushi seed 5 vacuum packaging is completed.

  In this case, when the frozen sushi seed 5 is transferred to the separately prepared lower film sheet 3 for finishing packaging and the upper film sheet 16 is placed on the lower film sheet, vacuum packaging can be performed more reliably.

The film 2 is then packaged at predetermined intervals for each group of 5 sushi seeds, each of which is a combination of about 10 sushi seeds 5 such as persimmons, squid, shrimp and conger. Since the lower film sheet 3 and the upper film sheet 16 are directly formed on the upper and lower films 2 in the surrounding film 2 for each of the five groups of seeds, the adhesive film 20 is used as a cutting margin for cutting. It is used and divided into 5 groups of sushi seeds packaged by a plurality of films 2 (FIG. 3, although a cocoon is shown for ease of understanding, the cutting means is not limited thereby).
Therefore, the efficiency and workability of the freezing and packaging work for the sushi seed 5 can be improved.

  Thus, the shaving balls 25 are formed in advance by hand or by a device called a shaving ball manufacturing machine (robot) and a person skilled in the art, and the formed shaving balls 25 are laid on the upper surface of the transport tray 1. The film sheet 24 is transported together with the transfer tray 1 and frozen by the refrigerator 12.

  In this case, it is preferable that the sharp balls 25 supplied from the sharp ball manufacturing machine 31 are directly received by the dedicated transport tray 1 and frozen together with the dedicated transport tray 1 by the refrigerator 12 because the working efficiency is improved. (Fig. 19)

  The frozen shari balls 25 are wrapped and placed on a warp 26 made of paper or wood, equivalent to about 10 servings of sushi seeds 5, and the shaving balls 25 and film 2 of the warp 26 are placed. As a set, the sushi seed 5 is stored in a cosmetic box 28 for transport and sold and distributed (FIG. 15).

  The consumer purchases the nigiri sushi 4 in the cosmetic box 28, heats the shari balls 25 in the microwave cooking machine (microwave oven) together with the shari balls 25 of the warp 26 at home. In the meantime, the sushi seed 5 of the film 2 is forcedly thawed with running water (including warm water), and when the sushi seed 5 is completely thawed, the sushi seed 5 is stacked on the shari ball 25 to complete the nigiri sushi 4.

  In this case, the heating of the shari balls 25 is about 2 minutes, and the sushi seed 5 can be thawed in about 2 minutes. Therefore, the heating of the shari balls 25 is performed simultaneously with the microwave cooking machine. If the sushi seed 5 is thawed as it progresses, “sushi in 2 minutes” can also be made at the dining table.

That is, since the sushi seed 5 vacuum-packed by the film 2 is cut into a predetermined size for use in the nigiri sushi 4 for one piece, each time the nigiri sushi 4 is eaten at home, the sushi The work of making sashimi to make seed 5 is omitted, not only remarkably time-consuming, but also professional craftsmen can enjoy nigiri sushi 4 by sashimi seed 5 cut by professional craftsmen it can.
Therefore, easy nigiri sushi 4 can be provided to people who have never held a kitchen knife or to a home without a kitchen knife.

  However, kohada, conger, etc. are formed into sushi seed 5 that has been pre-treated with “vinegar tightening” and “boiled” in advance, and this sushi seed 5 is frozen. Nigiri Sushi 4 can be provided to the home.

  In addition, it takes considerable skill to grasp the shari ball 25, but since the shari ball 25 is set according to the number of sushi seeds 5 cut, the nigiri sushi 4 held by the craftsman is also used in this point. Can be provided.

  And when each sushi seed 5 is frozen and packaged, the lower film sheet 3 for finishing wrapping of the film 2 and the upper film sheet 16 are within a range in which the number and type of each sushi seed 5 can be distinguished. Since they are welded so as to overlap each other and vacuum-packed, they are not only free of unevenness in freezing, but also when sushi seeds 5 are thawed, sushi seeds 5 with no unevenness of thawing are not required especially at home. It can be provided and is preferable.

  That is, the film 2 is formed with water resistance, and the lower film sheet 3 and the upper film sheet 16 are formed around each sushi seed 5 wrapped by the lower film sheet 3 and the upper film sheet 16. Since the close contact portion 20 that is in direct contact with the top and bottom is formed, the film 2 and each sushi seed 5 can be directly thawed with running water (including warm water), thereby facilitating the thawing operation.

  In addition, each sushi seed 5 wrapped by the film 2 can be applied with running water almost independently by the close contact portion 20, so that the passing time in the so-called "ice temperature (0 degree)" state is shortened as much as possible. It can be thawed and sushi seed 5 with excellent taste immediately after being cut by the craftsman can be supplied to the home.

In addition, the cook can apply the running water to each sushi seed 5 in the film 2 while holding the entire film 2, so in addition to the approximate time to apply the running water, the sushi seed 5 can also be thawed. Therefore, thawing work can be performed while taking into consideration the time until eating, and it can be thawed easily and accurately, and there are few failures.
Therefore, since there is a close contact portion 20 between each sushi seed 5 packaged by the film 2, not only whether it is a favorite sushi seed 5, but also thawing can be facilitated / accurate. It becomes.

  Thus, since the shari balls 25 constituting the frozen nigiri sushi 4 are packaged by a warp 26, they can be heated if they are set in the microwave cooking machine 30 together with the warp 26. It is.

  That is, when the shrimp balls 25 are heated in a container such as a resin bag, the container itself becomes hot and difficult to take out. It can be used, and the tree 26 itself is not heated, and the tree 26 can be transported to any place such as a table.

Next, when the thawed sushi seed 5 is placed on each shari ball 25 heated to a predetermined temperature, the nigiri sushi 4 is completed.
In this case, since the shari balls 25 are heated separately from the sushi seed 5, the use of the microwave cooking machine is less likely to occur, and the reliability of manufacturing the nigiri sushi 4 (thawing and grasping work) is improved.

  In addition, the sushi seed 5 and the shari ball 25 are each at an optimum temperature, the sushi seed 5 is cold, and the shari ball 25 is slightly warm, thereby realizing the exquisite temperature difference of the nigiri sushi 4 and improving the taste.

  In addition, the purchaser can taste the handmade feeling of food (food cooked by himself) by heating the shari balls 25 and placing the sushi seed 5 on the shari balls 25, further improving the taste, Or the satisfaction in providing nigiri sushi 4 to a family (person) is obtained.

  As described above, the nigiri sushi 4 of the present application is provided without requiring any skill in the three points of “cutting, grasping, and thawing technology”. Can be provided.

  Therefore, the size of one sushi seed 5 (rice cake 7) of nigiri sushi 4 is set to a size corresponding to the mouth size of various people, such as for elderly people, for children, for general use, Since the lower film sheet 3 is used for packaging, it is possible to expand the consumer's product selection range, which is preferable.

  In addition, the sushi seeds 5 that are vacuum-packed by the film 2 are not only sold as a set of the shari balls 25 of the warp 26 and the sushi seeds 5 of the film 2 and stored in a cosmetic box 28 for transportation. About 10 sushi seeds, such as salmon, squid, shrimp, conger, etc., each of which is individually packed and packaged, or 10 per unit of salmon, squid, shrimp, conger, etc. Since it can be packaged and sold, it is preferable because it makes it easy for consumers to select products.

  In addition, since kohada, conger, etc. are formed in the sushi seed 5 that has been pre-treated with “vinegar tightening” or “boiled”, nigiri sushi 4 held by craftsmen can be provided to the home.
