Abstract

PURPOSE:To carry out the hygienic packaging of a rice cake, and to improve the preservability of the cake, by placing a fresh pounded rice cake on a synthetic resin film, putting the cake supported by the film on a tray, temporarily sealing the cake with a covering film, and tightly sealing after the cooling of the rice cake. CONSTITUTION:The fresh pounded rice cake 3 is squeezed out on to the synthetic resin film 1 while pulling out the film 1 along the direction of the arrow 2, and is formed to a lump having a definite volume. The film 1 is cut to a definite length, and the cut film 1 supporting a definite number of the rice cakes 3 is put into the tray 4. The top of the tray 4 is covered with the covering film 5, and sealed temporarily with hot-pressing. After the spontaneous cooling of the rice cake, the covering film 5 is bonded tightly to the trary to effect the tight sealing of the cake and obtain a cake having excellent preservability and minimized hardening tendency.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a method of quickly packaging freshly pounded rice cakes to prevent deformation and delay hardening as much as possible, so that the rice cakes can be delivered to consumers while remaining soft. This relates to a packaging method.

The packaged mochi currently sold at ℃ is packaged in a rectangular plate shape or round shape (offering mochi) with an airtight film, but since it has already fallen and hardened, it cannot be eaten as is. In addition, in order to make the mochi a certain size, it is necessary to stretch the mochi and cool and harden it in the refrigerator. It is difficult for consumers to obtain freshly pounded mochi, and it is difficult for manufacturers to obtain mochi in large quantities, as it is more convenient to harden it for distribution. could not be produced.

However, according to this invention, the mochi is formed and placed on a film, the film is cut, and the film is placed in a film tray with bait, so the freshly pounded mochi can be prepared without removing the flour and without touching it. It can be handled industrially and, since it is protected within the tray, there is no risk of deformation during handling or display. In addition, since it is sealed with a covering film, the time of exposure to the outside air is extremely short (and because it is processed quickly while it is hot, it is extremely hygienic and the shelf life can be dramatically improved. Everything has improved.

The synthetic resin film for placing the molded rice cake in this invention should be used as long as it has appropriate toughness, has low adhesion to the rice cake, and can withstand handling after cutting the film until it is placed in the tray. I can do it.

In this invention, the covering film used in the present invention is preferably made of a material that is non-breathable and can be thermally bonded to the tray.If the flange of the film and the tray can be sealed by pressing and heating, the workability is good and continuous mass production is possible. suitable for For example, if a polyethylene film is laminated on the lower surface of a vinyl chloride film, it becomes non-air permeable and also has thermal adhesive properties, so that condition 7 can be satisfied. There are films binding with low adhesion of mochi, polyethylene film, Teflon film, silicone film, etc., but the above-mentioned film may be laminated to vinyl chloride film, or surface treatment may be applied to reduce adhesion. The material is not limited. Regarding the movement of the film on which the rice cakes are placed, a conveyor is normally used, or a synthetic resin film is used as shown in Figure 5. The method is not limited to this method, although it is punched out into a rectangular shape and moved by pulling the band-shaped residue.

Next, embodiments of this invention will be described. Synthetic resin film 17al - 3-inch film of freshly pounded mochi while being pulled out in the direction of the arrow! Squeeze it upwards, form it into an offering, and line it up at regular intervals. Then, the railm cake is cut into pieces of a certain length (for example, 6 pieces of rice cake).
) Place the film together with the film in the Hironai tray (Figure 2).

Next, the opening of the tray is covered with a covering film 5, and the film is temporarily attached to the peripheral edge of the covering film by heating and applying pressure to the rim of the rake as shown by the arrow 7. In this case, a part of the film is left unadhered so that the air inside the tray can be exhausted. For example, as shown in FIG. 6, if a recess is provided in the flange of the tray and the covering film 5 is adhered only to the flat part of the flange 6, a small gap will be created between the recess 4a and the covering film. This allows the internal nitrogen to be expelled.

The tray to which the covering film 5Y is temporarily attached as described above is left for about 2 hours to allow the cake to cool naturally, and then the unbonded portion of the covering film is thermally bonded to completely seal the tray (
Figure 7). In the embodiment described above, a recess is provided in the flange of the tray, but even if the recess is not provided, the same effect can be expected as long as there is a recess in a portion of the pressing and heating plate for the covering film. For example, if a recess io'5 is provided on the lower surface of the heating plate as shown in FIG. 5, the covering film facing the recess 10 will not be thermally bonded. Next, synthetic resin film l

) and cutting it into a rectangle /3 with a slight width /l' left between them. In the former case, there is no cutting waste and the entire film is stored in the tray as it is, so it must be moved by a conveyor or a special picking device (not shown). If you pull it in the direction of arrow /2, you can move the whole thing.

That is, according to the present invention, freshly pounded rice cake is placed on a synthetic resin film while being molded at a temperature of 0°C, the film is cut to a certain length, and the cut baited film is placed in a tray. After temporarily sealing the opening of the tray with a covering film, the mochi is sealed after cooling, which minimizes the time that the mochi is exposed to the outside air and prevents contact with human hands or dust. It has the effect of being able to be packaged hygienically. After the mochi has cooled, it is sealed (when the air in the tray is no longer expelled), so the air in the tray is relatively diluted, and there is less chance of bacteria adhering to it, so it has a good shelf life and retains moisture. It has a low evaporation rate (σ) and can remain soft for about a week if stored in an appropriate environment.

However, since the molding and packaging of mochi can be done in an integrated process and it can be shipped as is, there is no need to move on to the packaging process after refrigeration and curing as in the past, which saves time, labor, and equipment costs. There are various effects.
