Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for handling various high-temperature liquids or viscous liquids in so-called hot packs or hot fillings. A seal that cools a sealed bag filled with body parts to a predetermined temperature (high temperature) immediately after automatic packaging. This invention relates to a cooling device for bags.

0002

[Conventional technology]

For the purpose of sterilization, liquid or viscous material heated to around 90℃ is packed using an automatic packaging machine. The sealed bag that has been packaged as a seal prevents the contents from deteriorating, and can be immediately packed into bags or boxes. Immediately after packaging, the products are cooled to room temperature around 20-30℃ using a cooling device. However, as a device for cooling this sealed bag, for example, Japanese Patent Application Laid-Open No. 64-8483 There are cooling devices as seen in Publication No. 1 and Japanese Patent Application Laid-Open No. 1-254530. Ru.

[Problem that the idea aims to solve]

However, the conventional cooling device described above is not suitable for sealing bags (hot packs) immediately after automatic packaging. Since the cooling water is passed through a cooling water tank containing cooling water, it is necessary to use a sealed bag. If the product gets wet with water and does not dry, it cannot be packed in bags or boxes. If the cooling water is contaminated, it may remain in the seams of the installed film and cause sterilization or mold to grow. The cleaning process is troublesome, and the floor of the workplace is dirty with water, making it unsanitary and causing food waste. The entire cooling system including the cooling water tank is large and takes up a considerable amount of space, which is not suitable for packaging. There were various problems that could be addressed.

0004 Therefore, the technical problem of this invention is to use cooling water to seal bags immediately after automatic packaging. It is extremely easy and hygienic to cool the product and immediately pack it into bags or boxes. In addition, the purpose is to make the entire device as compact as possible.

[0005]

[Means to solve the problem] The measures taken in the present invention to solve the above technical problems are as follows. A high-temperature liquid or viscous substance is sealed and packaged using an automatic packaging machine, and immediately after this automatic packaging, The sealed bag is passed through a cooling chamber in an atmosphere of cooling air and cooled to a predetermined temperature. In the sealed bag cooler configured as follows, (1) Inside the cooling chamber, the sealed bag is transported back and forth through the entrance provided on the upper side. A multi-stage net conveyor that repeatedly transports the material gradually towards the lower exit. To provide. (2) These net conveyors of each stage should be installed with a space between them vertically.

[0006]

[Effect]

The above means works as follows. For the above (1), use cooling water to seal the sealed bag (hot pack) immediately after packaging. After cooling, it can be hygienically cooled and immediately packed into bags or boxes. , the cooling chamber can be made smaller by using a multi-stage net conveyor, and by extension the cooling system. Enables overall miniaturization.

[0007] The factor (2) above is whether the sealed bags fall downward at each stage of the net conveyor. As the filling moves inside the bag due to the reversal caused by this falling, this movement is repeated. The turning effect enhances the cooling effect of the filling and allows the sealed bag to be cooled accurately in a short time. and make it possible. As mentioned above, by solving the above-mentioned technical problem by the above-mentioned means, The problems of the conventional techniques can be solved.

【Example】

A preferred embodiment of the seal bag cooling device according to the present invention described above is attached below. This will be explained in detail with reference to the drawings. FIG. 1 is a side sectional view showing the overall configuration of the seal bag cooling device according to the present invention. In the figure, 1 is a cooling chamber, and 1a and 1b are inlets opened on the upper and lower sides of the cooling chamber 1. and indicates the exit. 2a, 2b, 2c, 2d, 2e are multi-tiered upper and lower inside 1n of cooling chamber 1. In the net conveyor constructed according to the formula, the starting end 2N of the top net conveyor 2a is A sealed bag PC (hot pack) immediately after being automatically wrapped by an automatic packaging machine (not shown). The outdoor automatic packaging machine is opened from the above entrance 1a so that the The terminal end 2Z of the net conveyor 2e at the lowest stage is projected toward the cooling chamber. In order to accommodate the sealed bag PC cooled in the storage box 5 etc. in the storage box 5, etc. It projects toward the outside from the outlet 1b.

[0009] Each of the above-mentioned net conveyors 2a to 2e is constructed entirely in a net shape as shown in FIG. A mechanism in which the conveyor is rotated according to the rotation of the sprocket 3a attached to the rotating shaft 3. However, the number of stages of the net conveyor and its rotation means are arbitrary. Also, above In each of the net conveyors 2a to 2e shown below, the sealed bag PC is transported from the upper conveyor to the lower conveyor. Leave space between the top and bottom so that they will turn around and fall towards the conveyor, and In order to be able to receive the sealed bag PC, the lower end is lower than the upper end 2X. The starting end 2Y is configured to be slightly longer.

0010 Next, in Figure 1, 4 is a refrigerator (cooler) that sends cooling air into the cooling chamber 1. Thus, 4a and 4b indicate cooling circulation pipes connected to the cooling chamber 1. Also, M is This is a motor that interlocks and rotates each of the above-mentioned net conveyors 2a to 2e.

[0011] Since the seal bag cooling device according to the present invention has the configuration as described above, the cooling chamber 1 Each net conveyor 2a to 2e is conveyed and rotated while sending cooling air from the refrigerator 4 inside. If you transport the sealed bag PC... at the entrance 1a at a temperature of about 90℃ immediately after packaging The sealed bag PC (hot pack) sent into the cooling chamber 1 is placed in a multi-stage container. It is gradually cooled while repeating reciprocating conveyance on the conveyors 2a to 2e, and exits 1b. By the time it comes out, it is cooled to room temperature of 20 to 30°C and stored in the storage box 5.

0012 Also, during transportation, the bottom of the sealed bag PC is passed through the mesh of the net conveyors 2a to 2e. The sides are also cooled uniformly, and the filling is turned over when it falls onto the lower conveyor. As it moves repeatedly within the seal bag PC, an excellent cooling effect is exhibited and the seal bag PC By the time it leaves the exit 1b, it has been cooled to a state where it can be packed into bags or boxes as it is.

[0013]

[Effect of the idea]

As described above, according to the seal bag cooling device according to the present invention, hot bags immediately after packaging can be heated. It is possible to cool the plastic bags to a state where they can be packed directly into bags or boxes. However, with this invention, the sealed bag can be cooled by cooling air without passing cooling water. Therefore, the sealed bags can be cooled hygienically and extremely easily, and the sealed bags can be cooled in multiple stages. The seals are conveyed and cooled by repeatedly dropping and reversing on a type of net conveyor. This has the advantage of allowing the bags to be cooled uniformly in a short time, making it easier to pack them into bags after heating. We aim to save labor and energy by performing post-processing such as packaging and packaging in a short time. It is possible to achieve an economical effect by using a multi-stage conveyor. Combined with the fact that the entire device can be made smaller and space-saving, its practical effects are extremely high. It's expensive.
