Description

  More particularly, the present invention relates to a lid made of resin that replaces a conventional wooden box, and mainly relates to a lid that is used for producing solid edible straw. .

  Rice bran is a rice, wheat, soybean, etc., cultivated with Aspergillus oryzae, and is used for various purposes such as sake, miso, soy sauce, mirin, amazake, pickles, and is essential for Japanese food. In recent years, cocoons are often mass-produced using a large circular iron making machine, but in order to produce high quality cocoons in small lots, the traditional cocoon lid method using a wooden box of about 30 x 45 cm is also available. It is still widely practiced. In general, rice bran by this cocoon lid method is chilled steamed rice, sprinkled with a koji mold, left overnight in a cocoon room, and then placed in a rectangular wooden box called a cocoon lid or box jar and heat treated. Manufactured.

When manufacturing a cocoon by this cocoon lid method, a wooden box is always used as the cocoon lid. This is because the wood is used for producing cocoons such as moisture conditioning, water absorption, CO ₂ adjustment function and heat retention. This is because it has an indispensable function. If the lid does not have these functions, moisture will accumulate in the lid, which will cause condensation and adversely affect the breeding of the straw and the quality of the straw and cannot become a product. . Therefore, it is unthinkable in the bag industry to use a resin container or metal container that does not have the above function as the lid.

  However, it is not perfect as a wooden box, and if it keeps moisture for a long time, the wood may become brittle, wood chips may be generated and mixed into the product, and it is durable due to repeated moisture absorption and drying There is a problem that it is inferior to that, and is forced to be repaired and replaced. In addition, when the koji mold enters into the fiber of the wood, it becomes difficult to wash, and there is also a problem that when stored in summer, it becomes a target of worm-eaten.

As mentioned above, the wooden box used in the cocoon lid method has been used in spite of a number of problems. This is because it has a CO ₂ adjustment function and a heat retaining property. Conventionally, the use of a resin container or a metal container that does not have these functions has never been considered in the coffee industry.

Therefore, the present invention creates a cocoon lid that can be provided with moisture conditioning, water absorption, CO ₂ adjustment function and heat retention according to the case of a wooden box while being made of a resin, so that foreign matter contamination that occurs in the case of the wooden box is created. To solve the problems of durability deterioration, poor cleaning performance, high cost, etc., that is, to provide a lid that is excellent in durability and can be supplied at low cost without problems of dew condensation and foreign matter. Is an issue.

  Condensation almost always occurs when a cocoon is made with a plastic jar lid. In other words, when the koji mold eats rice, it generates heat like humans, thereby raising the temperature inside the koji lid. In the filling process in the lid, the temperature is about 35 to 40 ° C. However, if this is put in the lid and stored indoors without temperature control, the product temperature rises, and after several hours, the temperature rises to 50 ° C. or more. Therefore, since the koji mold is killed, it is necessary to always control the indoor temperature.

  As described above, the temperature rises due to the heat generation of the koji mold on the inner side of the lid, and the outer side is cooled by the cold air for temperature control. As a result, a temperature difference occurs between the inside and the outside. As a result, the occurrence of condensation is inevitable. When this dew condensation comes into contact with the rice, the rice contains water, so that the gonococcus cannot propagate or the enzyme does not come out even if it is propagated, so-called “fool rupture” occurs. Therefore, when using a resin lid, it is necessary to devise measures to prevent the generated condensation from coming into contact with rice on the assumption that the occurrence of condensation is inevitable.

In order to solve the problem of condensation that is unavoidable when using a resin lid, the present inventor has conducted earnest research from such a viewpoint.
1) Means for preventing contact with rice even if condensation occurs 2) Means for making the situation where condensation itself is less likely to occur, and
3) It is necessary to take measures to prevent the occurrence of condensation, and the present invention has been completed upon obtaining knowledge that combining these measures is more effective.

  That is, the invention according to claim 1 devised to solve the above problems is a plastic lid, a container having a depth corresponding to the thickness of the solid mold product to be manufactured, and And a peripheral wall extending at an upper end. The peripheral wall is provided with a means for preventing condensation from penetrating into the container.

  The dew condensation permeation suppression means in one embodiment is to provide the peripheral wall via a drop receiving step formed by extending the upper end of the container in the outer horizontal direction, in another embodiment. The dew condensation permeation inhibiting means is configured to incline the peripheral wall outwardly.

  Further, the dew condensation permeation suppression means in yet another embodiment is to horizontally provide the peripheral wall in a flange shape, and the dew condensation permeation suppression means in still another embodiment includes a plurality of ventilation holes in the peripheral wall. Is to drill.

  In one embodiment, a plurality of ventilation holes are formed in at least one of the wall surface and the bottom surface of the container, and the thickness of the resin constituting the container and the peripheral wall is 3 mm or less. The depth of the container is 50 mm or less.

  This invention is as above-mentioned, Comprising: The gutter lid concerning this invention consists of the container of the depth corresponding to the thickness of the solid koji product to manufacture, and the surrounding wall extended at the upper end of a container. In addition, since the peripheral wall is provided with means for preventing condensation from penetrating into the container, even if condensation occurs, the penetration of the peripheral wall is prevented from penetrating into the container, Occurrence of defects such as flaws is avoided, so it has the effect of producing high-quality cocoon products, and since it is made of resin, it can be mass-produced and can be supplied at a relatively low price. It is easy to stack, saves space for storage, is easy to clean and can be used for a long time while maintaining a clean condition.

It is a section fragmentary view showing other examples of composition of a lid according to the present invention. FIG. 6 is a partial cross-sectional view showing still another configuration example of the lid according to the present invention. FIG. 6 is a partial cross-sectional view showing still another configuration example of the lid according to the present invention. It is a figure for demonstrating the state of total destruction.

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the accompanying drawings. A lid 1 according to the present invention is integrally molded with a resin, and a container 2 having a depth corresponding to the thickness of a solid basket product to be manufactured, and a peripheral wall 3 extending at the upper end of the container 2. The peripheral wall 3 includes means for preventing condensation from penetrating through the peripheral wall 3 into the container 2.

  The thickness of the resin constituting the container 2 and the peripheral wall 3 for incorporating steamed rice or wheat (hereinafter simply referred to as rice) as a raw material is 3 mm or less, preferably 1 mm or less, for example, 0.55 mm. The reason why the thickness of the resin is so thin is to promote heat dissipation and suppress the heat generation amount of the koji mold.

The depth of the container 2 is 50 mm or less, preferably 20 mm or less. Here, the depth of the container 2 is set to 50 mm or less, preferably 20 mm or less. When the thickness of the steamed rice lump 10 contained in the container 2 exceeds 50 mm, the heat is difficult to escape and the back surface of the steamed rice lump 10. This is because heat is likely to be trapped between the inner surface of the container 2 and the inner bottom surface of the container 2, and CO ₂ is easily accumulated therein. The lower limit is usually about 10 mm.

If the heat is trapped between the back surface of the steamed rice lump 10 and the inner bottom surface of the container 2, the steamed rice on the surface side dries due to the temperature difference from the surface side, so that the koji no longer propagates on the top surface. A malfunction occurs. Further, in that part, for example if a high concentration of CO ₂ in 2% or more is accumulated, the growth of the koji mold becomes considerably slow, Also, if a high concentration of CO ₂ of, adverse effects such not a koji Come out.

  The dew condensation permeation suppression means in the first embodiment is to provide the peripheral wall 3 via a drop receiving step 4 formed by extending the upper end of the container 2 in the outward horizontal direction (FIGS. 1 to 1). (See FIG. 3). In the case of this embodiment, since the peripheral wall 3 is provided via the drop receiving step part 4, in other words, it is provided at a distance from the container part 2, and therefore from the steamed rice mass 10 in the container part 2. The generated steam is unlikely to hit the inner surface of the peripheral wall 3. Even if some steam adheres to the inner surface of the peripheral wall 3 and dew condensation occurs due to a temperature difference from the outer surface to which cool air for temperature control hits, the dripping dew condensation is received by the drop receiving step 4. And staying there is prevented from penetrating into the container 2.

  The condensation permeation suppression means in the second embodiment is to incline the peripheral wall 3 outwardly (see FIGS. 1 to 3). The reason why the peripheral wall 3 is inclined outwardly in this way is to prevent the steam generated from the steamed rice lump 10 from hitting the inner surface of the peripheral wall 3 as much as possible. It can be said that the example shown in FIG. When the configuration of the second embodiment is incorporated in the configuration of the first embodiment (see FIGS. 1 to 3), a synergistic effect of the two can be expected, which is more preferable.

  The condensation permeation suppression means in the third embodiment is to provide the peripheral wall 3 horizontally in a flange shape (see FIG. 4). This can be said to be the ultimate form of the second embodiment. In the case of the third embodiment, no condensation occurs because the steam does not hit the peripheral wall 3. Even if condensation occurs on the peripheral wall 3, it does not penetrate into the container 2.

The dew condensation permeation suppression means in the fourth embodiment is to make a large number of ventilation holes 6 in the peripheral wall 3. In this case, it is preferable that a large number of small ventilation holes 7 are formed in at least one of the peripheral surface and the bottom surface of the container 2. By providing the ventilation holes 6 and 7 so as to provide air permeability in this way, it is difficult for condensation to occur on the peripheral wall 3, and an appropriate heat dissipation effect and CO ₂ emission effect are obtained in the container _2. It is done.

  The cocoon lid method using the cocoon lid 1 according to the present invention is different from mass production using a large-scale circular iron making machine that is mass-produced. For example, in a small box of 30 cm × 45 cm, cultivation is performed by entrusting the growth of koji molds. Because it is a method, it is prone to become a “total erosion” trap. In addition, “total breakage” means “breaking around”, that is, hyphae extending toward the surface of the rice, and “breaking up” This refers to the state in which hyphae extend at the same time in the center of the rice (see FIG. 6). The more “breaking”, the more sweet.

  The rice cake lid according to the present invention was developed mainly for the purpose of mass production of edible rice cakes. For example, the steamed rice cake 10 is placed in the container 2 having a depth of about 20 mm, and is kept warm in the rice cake chamber. A plate-shaped edible rice cake having a thickness of about 15 mm can be produced by drying and solidifying after culturing.

  As described above, the lid according to the present invention includes the container 2 having a depth corresponding to the thickness of the solid soot product to be manufactured, and the peripheral wall 3 extending at the upper end of the container 2. However, there is provided means for preventing the condensation from penetrating into the container 2. Therefore, even if dew condensation occurs, the permeation deterring means of the peripheral wall 3 prevents dew condensation from penetrating into the container part 2, so that the occurrence of defects such as fool rupture is avoided, and therefore, good quality, In particular, it enables mass production of solid food products suitable for edible use.

  And since the lid according to the present invention is made of resin, it can be mass-produced and can be supplied at a relatively low price, it is lightweight and easy to handle, stackable, does not take up storage space, easy to clean and clean. The advantage of the resin product that it can be used for a long time while maintaining it is enjoyed, and the industrial applicability is great.
