Description

  The present invention relates to a rice cooking net that is disposed inside a rice cooker, puts rice or the like from there and cooks rice, and takes out the rice from the rice cooker.

  For example, as described in Patent Document 1 below, the rice cooking net is disposed inside the rice cooker, and rice is added from above to cook rice, and the cooked rice is taken out together with the net, for example, In sushi restaurants, transfer the rice on the cooking net to a suitable container and cool it immediately, or take out the whole rice and cool it with the net attached, and then put the rice on the net in a suitable container. In any case, including in the case of restaurants and food manufacturers who do not need to cool the cooked rice, such as sushi restaurants, use a rice cooker immediately, It is necessary to cook as much rice as necessary for the day. If the net for cooking rice is not used, it takes time to take out the rice adhering to the inside of the rice cooker, and it also takes time to wash the rice cooker with rice. A rice cooking net is conveniently used to reduce such labor. Even in ordinary households, there are a few households that use rice cooking nets, but those who cook rice are working for companies, etc., parents with nursery school children and working for companies, etc. If this is the case, it is extremely useful because it saves the trouble described above.

  In addition, as described in Patent Document 2 below, as a net material, a net made of synthetic fiber yarn such as polyester or nylon can be easily folded and stored. is there.

    However, the net for cooking rice made of synthetic fiber yarn can minimize the adhesion of cooked rice to the rice cooker, but to remove the rice adhering to the net as much as possible from the net and make it edible There is a problem that it takes considerable time. Washing off the rice adhering to the net wastes rice and costs.

  This invention solves said subject and provides the rice cooking net which can peel off the rice adhering to a net from a net easily with the net for rice cooking which consists of synthetic fiber yarn, and can reduce the effort. is there.

In order to solve the above problems, the rice cooking net of the present invention has the following configuration.
(1) A rice cooking net made of synthetic fiber yarn, the surface of which is coated with a silicone resin.
(2) In the rice cooking net as described in the above item (1), the silicone resin is preferably a silicone resin that is three-dimensionally crosslinked.
(3) In the rice cooking net described in the above item (1) or (2), the synthetic fiber yarn is preferably a polyester fiber yarn or a nylon fiber yarn.

  [1] The rice cooking net of the present invention can provide a rice cooking net that can easily peel off the rice adhering to the net from the net and reduce the labor.

  [2] In the rice cooking net described in the above item (2), since the silicone resin is a silicone resin that is three-dimensionally cross-linked, the peelability from rice is good, and the heat during rice cooking is good. Is stable and does not deteriorate immediately, and can be used for a relatively long period of time.

  [3] In the rice cooking net described in the above item (3), polyester fiber yarns or nylon fiber yarns are used as synthetic fiber yarns. This is also preferable because there is little contamination of the rice with the additive added to the fiber material.

  Hereinafter, in order to facilitate understanding of the present invention, a few representative embodiments of the present invention will be described. However, the present invention is not limited to these embodiments.

  The synthetic fiber yarn used for the net of the present invention is not particularly limited as long as it is a material that can withstand the temperature inside the kettle when cooking rice and water or water vapor, but typically, for example, polyethylene terephthalate or polyethylene naphthalate. Typical examples include polyester substituted with phthalate and the like, and polyamide (nylon) substituted with nylon 6, nylon 66, and the like. In particular, polyesters such as polyethylene terephthalate and polyethylene naphthalate are preferable because they do not cause discoloration due to heat and the contamination of the additives with rice. Nets made of these materials are not particularly limited, but nets knitted by weaving or knitting manufactured from yarns or strings of these materials are preferably used, and nets formed by weaving are particularly strong. Is more preferable.

  The size and shape of the mesh are not particularly limited as long as the rice is supplied on the net so that the rice does not pass through the net and the water and steam easily pass through. For example, the shape of the mesh holes is arbitrary, such as a square, rectangle, triangle, other polygon, circle, ellipse, etc. The size of the mesh varies depending on the shape of the holes, for example, the shape of the mesh holes is rectangular. In this case, if the longer side is larger, such as 4 mm, and the shorter side is 1 mm, the rice hardly slips through the net mesh. As described above, the rice slips through the net mesh. The size and shape of water and steam can be easily passed. The most typical mesh hole is not particularly limited, but a typical example is a square with a side of about 1.5 mm, or a rectangular hole with a long side of about 2 mm and a short side of about 1 mm. .

  Examples of silicone resins for coating the synthetic fiber yarn constituting the net include various known silicone resins, for example, silicone for coating manufactured by Toray Dow Corning Co., Ltd. and resin under the trade name “Shin-Etsu Silicone” manufactured by Shin-Etsu Chemical A silicone resin of a type that can be three-dimensionally cross-linked is preferable from the viewpoint of release, heat resistance, adhesion strength, and the like. Specific examples include, for example, polydimethylsiloxane and hydrogensilane (terminal vinyl group introduced) A typical example is a curable silicone resin capable of forming a three-dimensional cross-linked structure by reacting a polydimethylsiloxane having —H group at the terminal with a platinum catalyst.

  The method of coating the synthetic fiber yarn net with the silicone resin is not particularly limited, and the dipping method is simple. However, the coating method is not limited to this method.

  More specifically, for example, a liquid (liquid A) in which platinum, which is a metal catalyst, is mixed at room temperature with polydimethylsiloxane having terminal vinyl groups introduced therein, and polydimethylsiloxane and hydrogen having terminal vinyl groups introduced therein. Synthetic fiber yarn nets are passed through a bath of liquid in which silane is mixed in a vacuum state at about 140 to 160 ° C. (liquid B), for example, in a ratio of about 10 liquid A to B liquid 10 by weight. Examples include a method in which these liquids are attached to a net of synthetic fiber yarns by a dipping method and heated at about 180 to 200 ° C. to three-dimensionally crosslink the silicone resin.

  The overall shape of the net is preferably a sheet, which is cheap and easy to fold and can be kept small. However, if necessary, a solid shape that follows the shape of the inside of the rice cooker, and other needs. A three-dimensional shape such as that described in Japanese Patent Laid-Open No. 7-227355, FIG. 5, FIG. 8, or FIG.

  As described above, the rice cooking net of the present invention is placed inside the rice cooker, and when rice is cooked, the cooked rice is taken out together with the rice cooking net, the rice cooking net is taken out, and the rice is transferred to an appropriate container. In some cases, compared to a net made of synthetic fiber yarn without silicone resin coating, the percentage of rice remaining on the net is much smaller, and it takes more time to remove the adhering rice from the net. It is preferable because it provides a cooking rice net that is extremely easy to use.

  The rice cooking net of the present invention can be applied to the manufacture of rice cooking nets, and can be effectively used for rice cooking in various restaurants and food manufacturing industries.
