Abstract

PROBLEM TO BE SOLVED: To provide a food packaging apparatus capable of evenly spraying additives at the same time as gas replacing or filling.SOLUTION: Gas replacing or filling package is performed by joining a nozzle from an additive aerosol container to a gas introduction pipe for performing the gas replacing or filling package and by mixing the additives formed into aerosol with a gas.

Description

Detailed Description of the Invention

The packaged food of the present invention is a packaged food packaged in an airtight manner so that it can be stored for a long period of time, and can be used for long-term storage of food quality.

In general, food is oxidized by oxygen in the atmosphere to deteriorate the quality, and aerobic bacteria are propagated under oxygen.

For this reason, when packaging food, it is desirable to remove air (oxygen) in the packaging container as much as possible. In addition, in order to increase the effect, nitrogen gas or the like has been filled.

Therefore, a packaging method that removes air in the packaging as much as possible has been put into practical use. The main packaging methods include vacuum packaging, (nitrogen) gas replacement filling packaging, and an oxygen scavenger in the packaging container. There are packaging etc.

In recent years, many sealed with nitrogen gas filling are on the market.

Moreover, as disclosed in Japanese Utility Model Laid-Open No. 56-65869, food is sealed in an inner container having no gas barrier property, and a plurality of these are collected by vacuum gas replacement packaging together with an oxygen scavenger and an antioxidant. There is also a product that is sealed in an outer container (double-wrapped).

Problems to be solved by the invention

The conventional packaged food described above has the following problems.

In vacuum packaging, the contents are crushed and the appearance is bad.

Moreover, since it cannot fully remove air when it is not a vacuum, it is not suitable for the packaging of the foodstuffs which are significantly oxidized by a slight amount of oxygen and the flavor is impaired.

When a simple oxygen scavenger is used, it usually only absorbs oxygen, so the volume in the container decreases by the amount of oxygen absorbed by the oxygen scavenger, and the container may be partially dented. Is bad.

In addition, oxygen scavengers used in food packaging are often iron-based (metal-based), which cannot be incinerated, and there is a problem in terms of measures for environmental problems.

In addition, when an iron-based (metal-based) oxygen scavenger is used, it cannot be heated in a microwave oven.

When the antibacterial agent was encapsulated, the antibacterial agent was not uniformly applied, and corrosion from a portion where the antibacterial agent was not applied was inevitable.

Means for solving the problem

The present invention is characterized in that a molded food container using a sheet is sealed by gas replacement filling and packaging, and at the same time, the additive is uniformly sprayed and sealed, and a container made of a synthetic resin and having a gas barrier property The present invention provides an inventive gas replacement packaging system that accommodates food.

That is, when the additive is sprayed, an additive spray nozzle is installed in the gas introduction pipe, and is sealed by gas replacement filling packaging.

Embodiment 1 of the Invention

An embodiment of the packaged food of the present invention will be described with reference to FIG.

Here, the sheet having a gas barrier property generally means that the oxygen permeability is 7 to 8 ml / m ² · 24 h or less at a temperature of 20 ° C. and in a dry state.

As the gas cylinder 3, a well-known and public apparatus is used, and an inert gas such as nitrogen gas, carbon dioxide gas, or a mixed gas thereof can be used as the replacement gas.

As the additive aerosol container 4, a well-known and official device is used.

The inner diameter of the additive spray nozzle port 6 is preferably in the range of 0.1 to 0.6 mm.

Additives that can be used include existing food antibacterial agents, particularly antibacterial agents such as alcohol preparations and liquid smoke, and antioxidants such as vitamin C. Influenza virus inactivating agents suitable for foods can also be used. it can.

JP 2009-249350 A

Moreover, all additives, such as what supplements food by adding a flavor, can be used.

Note that the oxygen scavenger can also be enclosed in the food container.

Therefore, an additive spray nozzle 5 from the additive aerosol container 4 is joined to the gas introduction pipe 1 for gas replacement filling packaging, and the aerosolized additive is mixed with gas to perform gas replacement filling packaging. is there.

That is, in the apparatus in which the gas sprayed from the gas cylinder 3 is sprayed into the food container via the gas introduction pipe 1, the additive aerosol container 4 is interposed between the gas introduction port 2 of the gas introduction pipe 1 and the gas cylinder 3. The extended additive spray nozzle 5 is penetration-joined.

The additive spray nozzle port 6 is formed so as to penetrate substantially the center position of the inner diameter of the gas introduction pipe 1.

Therefore, by simultaneously operating the gas cylinder 3 and the additive aerosol container 4, the gas and additive are uniformly sprayed into the food container.

Embodiment 2 of the Invention

In the case of FIG. 2, the additive spray nozzle 5 is inclined at an angle of approximately 45 degrees toward the gas introduction port 2, and the additive spray nozzle port 6 is inserted substantially at the center position of the inner diameter of the gas introduction tube 1. This is a structure.

Compared to the first embodiment of the invention described above, the gas and additive are sprayed more uniformly into the food container.

Embodiment 3 of the Invention

In the case of FIG. 3, the additive spray nozzle 5 is installed in parallel with the gas introduction pipe 1 toward the gas introduction port 2, and the additive spray nozzle port 6 is inserted substantially at the center position of the inner diameter of the gas introduction pipe 1. This is a structure.

Compared to Embodiment 2 of the above-described invention, the gas and the antibacterial agent are more uniformly sprayed into the food container.

The invention's effect

The food packaging apparatus of the present invention can automatically spray the additive uniformly from the aerosol container simultaneously with the gas replacement filling and simultaneously with the replacement gas, and thus has the following effects.
1. The effect of additives such as antibacterial agents and antioxidants can be added at the same time as air is blocked by gas to prevent oxidation.
2. By uniformly spraying the additive, the additive can adhere and penetrate.
3. The antibacterial agent can be uniformly sprayed with a slight improvement of the existing gas displacement device.
