Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses hot packs, normal temperature packs, low temperature packs, etc. to fill, for example, noodle soup, sauce, miso, and other suitable seasonings and appropriate foods or drinking water, pharmaceuticals, cosmetics, etc., as contents. By circulating a package made of plastic film or a plastic molded container, bottle, metal container (including canned can), which is floated and rotated in a circulating heating or cooling liquid to heat or cool. The present invention relates to a liquid bath type heating / cooling device for packages.

[0002]

2. Description of the Related Art Generally, for example, noodle soups, sauces and other suitable foods are enclosed as contents by hot packs, normal temperature packs or low temperature packs, and the contents are sorted according to a required amount and a required size and heated with a plastic film. A device that seals and cools cut individual packages, or a continuous bag-shaped part that encloses the contents and divides by the required amount and size and heat-sealed with a plastic film. An apparatus for heating or cooling a package is, for example, Japanese Patent Laid-Open No. 19112/1990.
What is shown in Japanese Patent Publication No. 9 is well known as a conventional example.

In this publication, for example, a device for stacking the individual packages in a pile on a belt conveyor and cooling them with a gas, and a required number of the individual packages for each pile or one on a net belt conveyor A device for cooling the container to a required temperature by passing it through the cooling water tank is mounted. The continuous package is heat treated by continuously passing through a heat treatment medium such as water, cooling gas, hot water, or steam contained in a heat treatment tank of a heat treatment apparatus. In this case, the passage is performed by, for example, spirally winding a plurality of times around the peripheral surfaces of the drums arranged above and below in the heat treatment tank, or by winding a plurality of windings in a figure 8 shape a plurality of times, during which the drum is transferred. According to the above, there is provided a device in which the continuous package is subjected to a pressing action and a partial bending action at the same time, the contents are forcibly fluidized and stirred, and the entire surface is heated or cooled.

[0004]

By the way, according to the above-mentioned conventional heating / cooling device, a wide heating / cooling space is required. Moreover, the heating / cooling treatment for the entire surface of the individual package or the continuous package is difficult to reach the core of the package, and not only the heating / cooling efficiency is extremely bad, but also the film is easily scratched. In particular, the continuous package is spirally wound a plurality of times around the peripheral surface of a drum in a heat treatment medium such as water, cooling gas, hot water, or steam contained in a heat treatment tank of a heat treatment apparatus,
Alternatively, in the case of a device that winds and transports a plurality of eight figures, if the bag-shaped part of the continuous package is small (for example, 5
10 to 10 cm x 5 to 10 cm or less) is good, but if it is large (for example, 10 to 15 cm x 10 to 15 cm or more), the device becomes large, requires a large installation area, and not only the cost is high, but also the volume is large. Since it becomes large, there is a problem that the heating / cooling treatment efficiency is further deteriorated.
