Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container for processing foods, etc., and more specifically, it relates to a container for processing foods, etc., and more specifically, a method for heating and steaming cooked foods, such as shumai, which can be steamed and served on the table while being placed in a packaging container. The present invention provides a processing container that can be used for processing.

Therefore, the container of the present invention is also useful as a container for processing articles that require steam sterilization, such as surgical instruments, in addition to foods.

Conventionally, packaging containers for frozen foods that require steaming before consumption, such as shumai, are typically packaged in bag-like containers made of a material such as plastic film.

However, since the container is not configured to directly steam the food, it is necessary to remove the food from the container and transfer it to a warmer such as a steamer to steam the food.

The present invention provides a container for processing foods, etc., which can be steamed without requiring the complicated work of taking the food out of the container, transferring it to a warmer, and steaming it as described above.

That is, the present invention consists of a compartment that stores water and a compartment that stores processed products such as food, and the partitions between the compartments are made of a porous plate and a microporous material that does not allow water to pass through but allows only steam to pass through. The present invention provides a container for processing foods, etc., which is characterized by the following:

Examples of the present invention will be explained in detail below using the drawings.

In FIG. 1, 1 is a flexible container body made of a shape-retaining material such as a metal sheet-synthetic resin sheet alone or water-resistant high-quality paper coated with wax, polyethylene resin, vinyl chloride resin, etc.; 2 is a flexible container body made of a shape-retaining material; Water A in the container body 1
Compartment 3 that stores food and compartment 4 that stores processed products B such as food.
It is a partition formed to constitute a.

Reference numeral 5 denotes a perforated plate, and the plate 5 is made of a plastic sheet, resin-treated paper, etc., with holes 51 formed therein, and the partition 2
to provide shape retention to the container 1.

The partition 2 is made of a microporous material such as paper mixed or coated with a water repellent, nonwoven fabric or cloth coated with a water repellent, or a polymer membrane (microfilter) having countless communicating pores of several microns or less. It is configured.

The former, i.e., paper, nonwoven fabric, cloth, etc., containing a water repellent agent repel water droplets and do not allow water to penetrate, but when water A stored in compartment 3 is heated, the surface tension of the water decreases. , and the wetting of paper and other fibrous tissues by water vapor, allowing not only steam to pass through, but also steam to pass through.The latter polymer membrane does not allow water to flow out under normal pressure, but when heated, water vapor is separated. By filling the chamber 3, steam passes through.

In this manner, the container of the present invention is capable of steaming the processed product B by heating the processed product B while it is packaged, thereby filling the compartment 4 in which the processed product B is stored with steam.

In the example shown in FIG. 2, the inside of the container 1 is partitioned by a perforated plate 5, and the water A is enclosed in the above-mentioned microporous material 2'.

The materials constituting the processing container of the present invention can be made of various materials as described above, and there are various heating methods such as hot water, microwave oven, oven, etc. Therefore, the materials constituting the container can be Materials that are not destroyed or altered by these methods are used.

Further, the compartment 4 that stores the processed product B such as food may be partially left open if it is undesirable for the product to become humid due to heating.

The processing container of the present invention is sealed to prevent water from flowing out, and the water is heated so that it becomes steam in the compartment where the processed product is stored. There is no need to take the product out of the container and steam it when heating it.
By heating the desired food in the container, it is possible to serve the desired food to the table, and therefore it is hygienic and convenient to carry.

Example 1 A rectangular container with a partition and a perforated plate (see FIG. 1) was made using high-quality paper coated with polyethylene resin on both sides.

For the partitions, a 5% solution of 100 parts by weight of methylhydrodiene polysiloxane and 10 parts by weight of dibutyltin dilaurate dissolved in hexane (
A microporous material was used which was coated with a solid material (solid content) and dried at 170°C for 3 minutes.

The perforated plate used was a high-quality paper coated on both sides with the above-mentioned polyethylene resin, in which many holes with a diameter of 3 mm were punched.

A small amount of water was poured into the partition side of the container thus formed and the container was sealed, and a frozen food was placed on the perforated plate and the container was sealed.

Add this to hot water (100℃) so that about 8 minutes of the container is covered.
When I opened the seal after leaving it for 5 minutes, I found that the frozen food inside had been completely steamed, just as if it had been steamed in a steamer.

Example 2 A fine powder of rhusium carbonate is blended into a compound material for soft vinyl chloride, formed into a film with a thickness of 20μ, and the film is passed through a hydrochloric acid bath to elute rhusium carbonate, thereby reducing the diameter to about 3μ or less. A polymer membrane with micropores of .

Enclose water with this film, place it in a styrene pot, and place the perforated plate used in Example 1 in the middle of the pot.
Frozen food was placed on top of this perforated plate, and the top of the pot was completely sealed.

Thereafter, when the mixture was placed in hot water and heated in the same manner as in Example 1, 0 fruit was obtained as in Example 1.
