Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a hermetically sealed packaging device used to hermetically package food in a plastic film bag when the food is frozen and preserved.

[Technical background of the invention]

Traditionally, to store food in a freezer or refrigerator, the food is stored in a plastic film bag and the opening of the bag is closed with a rubber ring, etc., or the food is stored in a container and the container is wrapped in a plastic film bag. I try to store it by wrapping it in a sheet and putting it in the freezer or refrigerator.

[Problems with background technology]

When using the above-mentioned conventional means, air remains in the bag or container containing the food, which tends to cause oxidation and drying of the food, resulting in poor storage stability. Friend, the air space is insulating, and in the case of frozen storage, it will take a long time until the food is frozen.
Therefore, there was a risk that the flavor of the food would deteriorate.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and an object of the present invention is to provide a hermetically sealed packaging device that can exhaust the air inside a plastic film bag and hermetically package food inside the bag.

[Summary of the invention]

In the present invention, the above object is achieved by sealing the opening of a plastic film bag containing food by heat sealing while the container is being evacuated.

[Embodiments of the invention]

In FIG. 1, the inside of an apparatus housing 1 is divided by a partition wall 3 having a suction opening 2 into a packaging chamber 4 having a large volume and a suction chamber 5 having a small volume. A solenoid 6 (hv) is provided in the upper part of the packaging chamber 4 with its shaft weighing against one side wall of the casing, and a heater 7 is provided below this solenoid. A U-shaped arm 8 is connected to the tip of the plunger 6a driven by the solenoid 6, and a pressing plate 9 facing the heater 7 is fixed to the end of the U-shaped arm.

A wind guide 11 is formed in the suction chamber 5 and connects the exhaust port 10 and the suction port 2 on the one side wall of the casing, and a fan 12 of an exhaust fan is disposed within this wind guide.

Further, pins 13 are provided on both sides of the heater 7 to support the bag B. In the figure, 14 indicates a fan motor.

A ninth opening 15 for putting in and taking out the bag Bt is provided on the other side wall of the housing 1, and this opening is provided with a door 16 that can be opened and closed to airtightly close the opening.

16g indicates a handle for operating the door, and 16b indicates a handle for operating the door.

In the apparatus of the present invention having the above structure, food is sealed and packaged in the following manner.

First, the door 16g is opened, and the bag B1 containing the food Ei therein is placed in the packaging chamber 4 with its opening near the heater 7 and sandwiched between the bags 6713.

Now close the door 16 and start the fan motor 14)1
The inside of the packaging chamber 4 is evacuated through the tube 12. After a certain period of time has elapsed, the air in the packaging room is exhausted and the heater 7 and solenoid 6 are energized, and the press plate 9 at the tip of the arm 8 and the heater 7
A portion of the bag B near the opening is clamped between the bag B and the bag B, and the opening of the bag B is sealed by heat sealing.

Next, the heater 7, solenoid 6, and fan motor 140 are de-energized. Then, the inside of the packaging chamber 4 becomes atmospheric pressure through the suction port 2 and the exhaust port 10t, so that the bag B is suppressed and brought into close contact with the food E inside. Further, since the pressure is at atmospheric pressure as described above, the door 16 can be easily opened and the bag B can be taken out from the opening 15.

Furthermore, since the pressure inside the packaging chamber 4 is uniform, wrinkles do not occur on the heat-sealing surface, and heat-sealing can be performed accurately. Further, the food E to be stored in the bag B may be either solid or liquid. Furthermore, the food stored in the bag B, its juice, etc. will not be sucked into the suction chamber, and hygienic sealed packaging can be achieved.

Figure 2 shows the solenoid 6, heater 7, and fan motor 14.
As shown in this figure, the heater 7 and solenoid 6 must be activated after the fan motor 14 is energized and the packaging chamber 4 is sufficiently evacuated. Therefore, a control circuit is used that includes a delay timer that energizes the heater 7 and solenoid 6 with a required time delay after the switch for energizing the fan motor is turned on, and a timer that stops the entire unit after heat fusion is completed. can be automatically sealed and packaged.

〔Effect of the invention〕

As mentioned above, if the device of the present invention is used, food can be sealed and packaged in a plastic film bag, so that no air layer remains inside the bag. There is no risk of food drying, oxidation, etc. due to its presence. In addition, since there is no air space, food can be frozen quickly during frozen storage, and there is no risk of spoiling the flavor of the food.
