Description

[Detailed description of the invention] [Industrial application field]

The present invention is a continuous package in which noodle soup, sauce, yakiniku sauce, and other appropriate liquid substances are sealed in hot packs, room temperature packs, or low-temperature packs, and are heat-sealed after being divided according to the required amount and size. A continuous strip of liquid material that is automatically packaged and immediately cooled to the required temperature (room temperature) if it is high temperature, or temporarily heated for sterilization if it is at room temperature or low temperature and then cooled. The present invention relates to a method and apparatus for processing a package.

[Prior art]

Conventionally, for example, a package containing a high-temperature liquid substance called a hot pack has a high temperature of approximately 85°C immediately after packaging, and it is difficult to carry out the subsequent boxing process etc. in that state. Therefore, it can be heated to the required temperature (room temperature) by heat treatment.
It was cooling down. The cooling means may be, for example, as shown in FIG. 4, in which the individual packages 23 cut from the heat-sealed portion 22 by the cutter 21 of the automatic packaging device 20 are piled up in one place and cooled naturally, or as shown in FIG. The required number of individual packages 23 cut from the heat-sealed portion 22 by the cutter 21 of the automatic packaging device 20 as shown in FIG.
It was cooled to the required temperature (room temperature) through the inside. However, in the former case of the above-mentioned conventional cooling means, the high-temperature individual packages are simply piled up in a pile, so the heat dissipation effect is very poor, and the individual packages located in the center are kept at room temperature. Not only does it take a long time for the package to be cooled down, but also because the cooling is done gradually, the growth of bacteria in the contents is promoted during the cooling process, reducing the shelf life of the package. In the latter case, cooling water speeds up the cooling time, but since the package is transferred while being placed on the net-like conveyor without being compressed, the contents themselves actively move within the package. The heat dissipation effect is not further promoted by stirring, and depending on the type of packaging, some may float on the surface of the water, resulting in insufficient cooling effect, and the packaging is removed from the water. When wiping off water droplets adhering to the surface of a container, there are problems such as it is difficult to do this automatically, reliably, and with high efficiency because each package is an individual package. . Furthermore, although cooling is not required in normal temperature packs or low temperature packs, it is necessary to sterilize the packaged contents by heat treatment. In this case, the sterilization treatment is indicated on the packaging bag as F=1 if the object to be sterilized is treated for 1 minute at a center temperature of 121℃, and depending on the contents, F=4 or higher may be required. There is also. Although the above-mentioned conventional example has been explained in the case of cooling, it is clear that similar problems will occur even when this is applied to heat sterilization. In order to solve this problem, an earlier invention was proposed in Japanese Patent Application No. 78087/1987 filed by the same applicant.
In the invention of this earlier application, a continuous band-shaped package filled with contents is passed through a cooling device continuously as it is, and a compressing action and a bending action are applied to fluidize and stir the contents to promote cooling. At the same time, it is extremely superior to the conventional example in terms of seal leakage inspection. Even when the invention of this prior application is applied to heat sterilization, it is superior to the conventional example in that the sterilization effect is promoted by fluidizing the contents.

[Problems to be solved by the invention]

However, in the invention of the earlier application, a screen roll that imparts a compressing action and a bending action when a continuous band-shaped package passes through a processing device in which a heat treatment medium for cooling or heating is stored. Since a plurality of guide members are disposed vertically in a zigzag pattern, the transfer length for heat treatment becomes long, which inevitably increases the size of the processing apparatus itself.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention conveys a continuous band-shaped package containing a liquid substance through a heat treatment medium, and during the conveyance, a pair of guide members disposed above and below, By winding the continuous band-shaped package multiple times in a figure-eight pattern, a compressing action and a partial bending action are simultaneously imparted to the continuous band-shaped package, thereby assisting fluid agitation of the contents and promoting heat treatment. A method for processing a continuous band-shaped package encapsulating a liquid substance, a processing device storing a heat treatment medium for cooling the continuous band-shaped package encapsulating a liquid substance, and a processing device in the processing device and a pressing device equipped with a pair of guide members that apply a pressing action to the continuous band-shaped package while conveying it in a stretched state in a spiral or figure-eight shape several times in the vertical direction. , the guide member is configured to partially bend the continuous band-shaped package, and provides a processing device for a continuous band-shaped package containing a liquid substance, wherein the guide member is configured to partially bend the continuous band-shaped package. By imparting a compressing action and a partial bending action to the strip-shaped packaging, fluid agitation of the contents is performed even more actively, thereby significantly accelerating heat sterilization or cooling, and continuous strip-shaped packaging. The processing apparatus in which bodies are conveyed in a spiral or figure-eight pattern can be significantly downsized.

The guide members 2a, 2b are driven in synchronization with the automatic packaging device A provided upstream of the processing device 1, and are driven by an appropriate drive mechanism (not shown) such as a gear or a chain. It's becoming like that. A pair of squeezing rolls 7 is disposed on the exit side of the processing device 1, for example, in order to remove moisture adhering to the continuous strip-shaped package a, and an air dryer 8 is disposed adjacent to the roll. will be established. This air dryer 8 has a plurality of air pipes 9 disposed facing each other, air blowing holes 9a are provided on the opposing surfaces thereof, and the continuous band-shaped package a passes between these air pipes 9. ing. In the figure, reference numeral 10 indicates a tension roller provided on the inlet side of the processing apparatus 1, and reference numeral 11 indicates a guide roller provided on the outlet side. And the automatic packaging device A
is commonly used, and 12
13 is a content supply nozzle, 14 is a vertical sealing roll, 15 is a horizontal sealing roll, and 16 is a heat sealing portion.

[Explanation of operation]

The heat treatment device for the continuous strip package of the present invention having the above configuration forms a continuous strip package a that is continuously sealed and filled with contents by the automatic packaging device A, and are continuously introduced into the processing device 1. In this processing device 1, a continuous strip-shaped package a is conveyed multiple times in a spiral or figure-8 shape between a pressing device 2, that is, a pair of guide members 2a and 2b disposed above and below, For example, the contents are heated or cooled by passing through a heat treatment medium. During the stretch conveyance by the guide members 2a and 2b, the continuous strip-shaped package a is partially dented by the rod-shaped member 3, and at the same time is subjected to a compressing action and stored inside. The liquid contents are moved and agitated within each package. That is, with respect to the rotation direction X of the guide members 2a, 2b,
Each successive package is rolled up and subjected to a compressing action, and the side that comes into contact with the rod-shaped member 3 is recessed corresponding to the rod-shaped member, and is partially bent at a plurality of places. By being in this bent state, the content begins to move from the end side in the advancing direction when winding, and when it is located at the top or bottom, the content is distributed evenly on the left and right sides. There is movement of objects, and furthermore, when descending, the contents move toward the front in the direction of travel, and when going up and down, the contents move toward the rear in the direction of travel. During these movements, because the rod-shaped member 3 is in a bent state with a portion being concave at multiple locations, turbulence occurs when the fluid moves, and a stirring action is inevitably imparted. It will become. Therefore, the continuous band-shaped package a is
When passing through the processing device 1, the material is conveyed vertically in a spiral or figure-eight shape, and furthermore, during the conveyance, it is stored in the upper and lower positions multiple times by the compression device, that is, the guide members 2a and 2b. Since the contents are compressed and stirred at the same time, they are evenly stirred and heat-treated quickly. When the heat treatment is cooling, cold water is stored in the processing device 1, and the high-temperature contents sealed in the continuous band-shaped package a by the automatic packaging device A in the previous stage are continuously stored in the processing device 1. By repeatedly bending and compressing the contents using the guide members 2a and 2b, the contents are evenly stirred and cooled quickly, keeping the contents at a temperature of 30 to 40 degrees Celsius, where bacteria are particularly likely to propagate. It is possible to quickly cool the contents to a lower temperature without spoiling the flavor of the contents. When the heat treatment is a sterilization treatment, boiling water or high temperature inside the treatment apparatus 1 is introduced into the treatment apparatus in the same manner as described above, and bending and compression are repeatedly applied by the guide members 2a and 2b. Stir the contents evenly to quickly sterilize the contents. especially,
In the case of sterilization treatment, the sterilization time can be set by appropriately selecting the number of wraps of the continuous band-shaped packaging body a around the guide members 2a and 2b and passing it through.For example, if the packaging bag is marked with F=2. For example, the number of wraps may be selected so that the passing time corresponds to this. In this sterilization process,
By applying high-temperature heat, the contents become boiled, but since they are sealed inside the packaging bag and are not oxidized, there is little discoloration and the color tone of the contents can be maintained in a good state. Furthermore, following the sterilization treatment by heating, a similar treatment device 1 is placed adjacent to the sterilization treatment, and the color tone and flavor are not impaired by rapidly cooling the food in the same way as in the case of the cooling described above. . Then, during the above-mentioned conveyance, the pressing device 2
Applying compressing and bending effects to the continuous band-shaped package a using the guide members 2a and 2b is a harsh condition, and by applying these effects multiple times, it is difficult to encapsulate the contents. If the heat-sealed portion is incomplete, the contents will leak from the sealed portion, and this will be visually inspected during transportation. Continuous band-shaped package a heat-treated by the above method
is conveyed from the outlet side of the processing device 1 through a squeezing roll 7 while removing moisture adhering to its surface, and then air dried in an air pipe 9 by an air dryer 8 as shown in FIG. Blowout hole 9a
Blow out dry air to remove water droplets adhering to the surface. After these steps are completed, each package is cut at the sealed boundary, resulting in a single package, which is then used for subsequent operations such as packaging.

【Effect of the invention】

As explained above, the method of heat treating a continuous band-shaped package encapsulating a liquid substance according to the present invention involves transporting the continuous band-shaped package encapsulating a liquid substance through a heat treatment medium, and disposing the continuous band-shaped package encapsulating a liquid substance vertically during the conveyance. A pair of provided guide members is wound spirally or in a figure-eight shape multiple times to apply a compressing action and a partial bending action to the continuous band-shaped package at the same time. The heat treatment is promoted by assisting fluid agitation, and in particular, by imparting the bending action, fluid agitation of the contents is extremely active,
In addition to uniformly heat-treating the contents, the material can be efficiently heat-treated by being conveyed in a spiral or figure-eight shape, and the time it takes to pass through the heat-treating medium can be shortened, improving workability. Without,
Whether it is cooling or heating, it is processed in a short time, so it has an excellent effect that the color tone and flavor of the contents are not impaired. Further, the heat treatment device includes a processing device that stores a heat treatment medium for cooling a continuous strip-shaped package containing a liquid substance as a content, and a processing device that stores a heat treatment medium for cooling a continuous strip-shaped package containing a liquid substance as a content, and in which the continuous strip-shaped package is stretched in a vertical direction. The compressing device is equipped with a pair of guide members that apply a compressing action to the continuous strip-shaped package while conveying the continuous strip-shaped package multiple times in a spiral shape. The bending structure ensures that the contents are fluidized and stirred actively to promote heat treatment, and that the pair of guide members disposed above and below can be bent in a spiral or figure-eight shape. By winding and conveying, the processing apparatus can be significantly downsized, and at the same time, by selecting the number of windings in accordance with the processing time, it is possible to carry out processing for a desired time, which is an excellent effect.
