Abstract

PURPOSE:To avoid a confusion between the foods before and after heat disinfection due to a difficult judgement from the appearance of their packages by filling the food in each of food receiving parts formed and arranged in a sequence in the longitudinal direction of a strip of film wrapping material and heat disinfecting the same after sealing. CONSTITUTION:Film wrapping material 7 is provided with food receiving parts 4 formed and arranged in a sequence in its moving direction at suitable spaces. A vacuum packing part 11 draws an upper film 13 wound into the form of a coil and covers the food receiving parts 4 containing the food 3 therewith from above for heat sealing while removing air therefrom. In the case of treatment by a continuous heat disinfecting device 16, a sequence of containers 1 in a folded or coiled form is drawn and placed, starting with the first one of the successive containers, in succession onto the conveyer leading to the disinfecting device 16 for heat disinfection. After disinfection by a heat disinfection device 15 or the continuous heat disinfecting device 16, a sequence of the containers 1 is introduced as such into a cooling part 17 for cooling and each container 2 containing the food is thereafter cut off by a cutter 18 separately from the continuous wrapping material, followed by the boxing operation.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for supplying food to the market in a hygienically safe state by sealing the food in a package made of a film packaging material made of synthetic resin or the like. This relates to a method of packaging food.

[Conventional technology and issues to be solved]

Conventionally, pre-cooked so-called retort foods and processed foods such as jams that are distributed in the market at room temperature, chilled foods and frozen foods that are distributed in a frozen state have been processed to prevent germs and dirt from entering from outside, and to protect consumers. In order to make food products easier to use and purchase, the food products are supplied to the market in packaged bags.

In this case, for mass production, for example, a band-shaped film packaging material made of synthetic resin is fed in the longitudinal direction, folded in two in the width direction of the package, and then heat-sealed at appropriate intervals in the longitudinal direction. A large number of bag-shaped food storage sections with side openings are formed in a continuous manner, or food storage sections are formed at appropriate intervals using a press mold while feeding a strip-shaped film packaging material in the longitudinal direction. After storing food in each food storage section, the food is sealed and packaged, and then each food storage section is separated to form a so-called bag containing food packaging, and then each food packaging is placed in a basket or packet. The product is placed in a heat sterilization chamber for a predetermined period of time, cooled, and then subjected to an inspection process before being packed in cardboard boxes and shipped to the market.

However, when the hermetically sealed package containing food is heat sterilized and then cooled to room temperature, no trace of the heat sterilization remains. If the packages are identical in shape when separated into individual bags, it is impossible to distinguish between unheated and heat-sterilized packages by appearance.

Therefore, there is a risk that workers may mistake unheated sterilized food for heat sterilized food and ship it to the market as is, which can lead to extremely hygienic situations such as food poisoning.

In order to prevent such accidents, it would be extremely time-consuming and costly to attach some sort of mark to each heat-sterilized food package or to carry out special monitoring. there were.

An object of the present invention is to solve the problems that could not be solved conventionally by devising different packaging forms for foods before and after heat sterilization treatment.

[Means to solve the problem]

To achieve this objective, in the present invention, food storage packaging bodies are formed using a band-shaped film packaging material so as to be continuous at appropriate intervals along the longitudinal direction, and food is placed in the food storage area of each of the packaging bodies. This food packaging method is characterized in that after being stored, the food packaging is sealed, and then the food packaging is heated and sterilized in a continuous state, and then the food packaging is cut into individual food packaging. .

[Action/effect of the invention]

In this way, food is stored in the food accommodating portion of each package formed by connecting a plurality of strip-shaped film packaging materials in a row along the longitudinal direction, and then the food is sealed, thereby forming a plurality of food-containing packages in a row. However, since the heat sterilization process is performed with multiple food-containing packages arranged in series, the food-containing packages are not separated into individual bags at least until the heat sterilization process is completed. do not have.

After the heat sterilization process, the food packages are separated one bag at a time, so the packaging form of the food is completely different before and after the heat sterilization process.

In other words, it is possible to clearly and extremely easily distinguish from the appearance the food-filled packages separated into individual bags after heat sterilization and the unheated sterilized food-filled packages connected together. be able to.

Therefore, according to the present invention, it is no longer possible to confuse food before heat sterilization with food that has undergone heat sterilization due to the appearance of food packaging, and at least it is possible to ship food that has not been heat sterilized to the market as is. This has the effect of completely preventing accidents, and eliminating the need for a special observer and marking of items that have been heat sterilized, as was the case in the past.

〔Example〕

Next, to explain an example, the reference numeral 1 shown in FIGS. 1 and 2 is a package group, and the package group 1 arranges the packages 2 containing food 3 in one row or in multiple rows on the left and right. , at least two or more of them are installed in series.

The packaging body 2' for containing the food 3 may be a single film made of soft synthetic resin, a laminated film made of a plurality of synthetic resin films, or a laminated film of a synthetic resin film or lumen and aluminum foil. After transporting these strip-shaped film packaging materials 7 in the longitudinal direction, food storage portions 4 are formed at appropriate intervals by bag making or pressure forming. , After storing the food 3 in the food storage section 4 of each package 2', air is removed (vacuum).
It is sealed and manufactured in a continuous band shape as described below.

The dotted lines 5, 5 in FIG. 1 are mark lines or weakened lines such as perforations indicating the locations where the food packages 2 are to be separated one bag at a time in a later step.

Next, a method for manufacturing the series of packages 1 and a method for heat sterilization will be explained together with an apparatus therefor.

Reference numeral 6 in FIG. 3 is a manufacturing device for the series of packages 1, and a starting end 6a of the manufacturing device 6 has a material supply section 8 in which a band-shaped film packaging material 7 made of the above-mentioned appropriate material is wound into a coil shape. The strip-shaped film packaging material 7 that has been provided and rewound from the material supply section 8 advances in the direction of arrow (A) and reaches the forming section 9 at the front position thereof.
By pressing a pair of upper and lower molds (not shown) at
Food storage portions 4 are formed in the film packaging material 7 at appropriate intervals along its traveling direction.

In the manufacturing device 6, the band-shaped film packaging material 7 is folded in half along the longitudinal direction at the midway point in the width direction, and heat-sealed at an appropriate distance from the front and back, thereby creating a food storage section with one side along the longitudinal direction open. 4 may be formed at appropriate intervals, or the food storage sections 4 may be formed by stacking two sheets of band film packaging material 7 and sealed on three sides at appropriate intervals, and the food products 3 may be stored in these.

Reference numeral 10 denotes a food supply unit that stores food 3 by dropping or pouring the food into each of the food storage units 4, and the food 3 supplied by the food supply unit 10 includes solid, granular, There are any retort foods and processed foods such as liquid or liquid. Note that the food 3 may be placed in the food storage section 4 manually.

Reference numeral 11 denotes a vacuum sealing section, which evacuates air while unwinding the coiled upper film 13 to cover and heat-seal the food storage section 4 in which the food 3 is stored.

A large number of food-containing packages 2 vacuum-packed in this way
It is possible to continuously produce the packaging rate-limiting 1 in which the film packaging material 7 is spaced apart at appropriate intervals in the longitudinal direction of the film packaging material 7, and the packaging rate-limiting 1 released from the terminal end 6b of the manufacturing device 6 is folded into the bucket truck 12. Store in condition. Incidentally, reference numeral 14 is a cutter device for cutting the packaging rate-limiting material 1 into appropriate lengths.

Instead of storing the rate-limiting packaging 1 in the bucket truck 12, it may be wound into a coil using a winding device (not shown).

Reference numeral 15 is a heat sterilization device, which uses a hot water tank, a steam heating device, an autoclave, a microwave heating device, etc.
When processing the rate-limiting packaging 1 in a batch manner, the rate-limiting packaging 1 may be loaded into and taken out of the heat sterilizer 15 while loaded on the bucket truck 12, or stored in a folded state in a basket mounted on the bucket 71/car 12. can be put in and taken out in units of baskets.

When the rate-limiting packaging 1 is wound into a coil, the coil may be placed in the heating sterilizer 15 for sterilization.

Furthermore, when supplying to the continuous heat sterilizer 16 in FIG. 3, the folded or coiled packaging rate-limiting 1 is unwound and continuously supplied from the starting end to the con-hair etc. of the continuous heat sterilizer 16, Sterilize by heating.

After being sterilized in the heat sterilization device 15 or the continuous heat sterilization device 16, it is cooled in the cooling section 17 with the packaging rate controlled at 1, and then cut into individual food packages 2 by the cutter section 18 and then packed. Good.

In this way, after storing the food 3 in the food storage sections 4 formed at appropriate intervals, the food-containing packages 2 that are sealed and packaged are continuously formed, and then a plurality of the food-containing packages 2 are arranged in a row ( Since the package 1) is heat sterilized as it is, it is determined that the package 1) has not been heat sterilized in such a packaging rate-limiting state.

After the heat sterilization treatment, the food-containing packages 2 are cut from the packaging rate-limiting 1 and separated into individual bags for shipment to the market. This makes it possible to clearly distinguish food products from those that have been sterilized, completely preventing the accident of shipping unheated and sterilized products to the market, and supplying hygienically safe foods to the market.

In addition, the rate-limiting packaging l in which a plurality of food-containing packages 2 are arranged in a row is easier to handle, such as loading and unloading the heat sterilizer, since it is more coherent than the food-containing packages 2 that are separated into bags. It will become.
