Description

The present invention relates to a kamaboko plate processed so as not to generate bubbles in the kamaboko. In particular, the present invention relates to a kamaboko plate that can produce a high-quality kamaboko with a plate that does not generate bubbles in the kamaboko.

In the kamaboko, a large number of small bubbles may be generated in a portion in contact with the kamaboko plate. Such bubbles are thought to be caused by air or liquid entering the kamaboko plate from the kamaboko plate conduit and expanding by heating. Therefore, Japanese Patent Publication No. 5-66097 provides a kamaboko plate in which a kamaboko plate conduit is sealed by treating the kamaboko plate with silicon resin or its inclusion.

  In a kamaboko with a plate, a large and small number of bubbles may be generated in a portion in contact with the kamaboko plate. Therefore, the kamaboko plate is treated with silicon resin or its contents (see Patent Document 1), and the kamaboko plate is sealed with a vinyl acetate emulsion so as to seal the kamaboko plate conduit. Provided (see Patent Document 2).

The present invention provides a kamaboko plate which is excellent in water resistance and heat resistance, and whose end is treated with an acrylic resin in which molecules penetrate into the conduit and does not expand after drying (see Patent Document 3).
The manufacturing method of kamaboko with a plate is a product made by placing raw fish surimi on a kamaboko plate and steaming it to promote protein denaturation of the raw material and cross-linking action due to salt content. Although natural wood board is excellent overall, it is still mainstream.

However, in the case of such a natural wood board, the kamaboko board absorbs the moisture in the surimi raw material containing moisture, and in the heating process at the time of manufacture, this moisture is vaporized by being heated above the boiling point, resulting in A product with air bubbles in the kamaboko is produced. Such a phenomenon, in particular, in the case of a high-class kamaboko, which examines the raw materials, has resulted in betraying the consumer's expectation for quality, and improvement has been demanded.

Japanese Patent Publication No. 5-66097 Japanese Patent Laid-Open No. 7-327643 JP 2003-319765 A

When the kamaboko board processed using the silicon resin and its content is stocked over a long period of time, for example, for about 1 to 10 months, the kamaboko board may be cracked. Moreover, the kamaboko board processed with the vinyl acetate emulsion has a problem that the bubble prevention effect is small. In addition , it provides a kamaboko plate which is excellent in water resistance and heat resistance, and has a wood end treated with an acrylic resin in which molecules penetrate into the conduit and does not expand after drying, but does not show sufficient effects.

An object of the present invention is to provide a kamaboko plate which is free from bubbles in the kamaboko and does not have a scent odor, assuming that a natural wood board is used.

The reason why cracks occur in the mouth of the kamaboko board treated with silicon resin or its inclusion is considered as follows. That is, since the silicon resin has a small molecule, it easily penetrates deep into the conduit of the tree, and the silicon resin has a property of expanding when dried. When the silicon resin that has penetrated deeply into the wood conduit dries and expands, the kamaboko board cannot withstand this and cracks occur in the mouth. As a result of various investigations on vinyl acetate, acrylic acid, etc., the molecule is large and difficult to penetrate deeply into the wood conduit, so it does not show a sufficient effect.

In addition, it has been concluded that the above problem can be solved by using a polyurethane resin that does not expand even when dried. The present invention provides a kamaboko board characterized by treating the end with a polyurethane resin.
This is a firewood board that has been treated with a polyurethane resin to reduce the moisture in the wood by heating cedar and fir for firewood board.

The heat treatment of the cedar and komaboko board is steamed at 90 ° C. to 150 ° C., and then treated at 80 ° C. to 150 ° C. for 1 to 10 hours to make the moisture content of the wood 5 to 10% . The treatment was preferably performed at 90 ° C. to 140 ° C. for 2 hours to 8 hours, and the effect was shown by treating an appropriate inside from the outside of the plate portion. Moreover , it is desirable that the cedar and the fir are dried by gradually lowering the temperature from 120 ° C. so that the residual water content of the cedar and the fir is 5 to 10% .

The polyurethane resin has a molecular weight of 1000 to 10,000 and is used by being dissolved and dispersed in a solvent, and preferably has a molecular weight of 2000 to 9000. If the molecular weight is large, it will not enter the cedar and fir conduits (temporary conduits) , while the smaller ones will go deeper into the conduits and increase the usage. Cedar, the butt end portion of the fir brush, spray or the like, are those small amounts, yet to uniformly apply.

The action of the present invention is to remove the resin portion in the conduit on the mouth end of cedar and fir with water vapor and treat the end with a polyurethane resin.
This polyurethane resin solution can be applied to both surfaces of the kamaboko plate 1 knot 2 using a brush, spray gun, roller or the like (10-25 m 2 knot applied to 1 L of this liquid).

Sometimes both sides of the two ends of the polyurethane resin are soaked in the mixture of polyurethane resin. The polyurethane resin emulsion is used in an amount sufficient to plug the conduit. As an example, in the case of a spray gun, an amount that the paint floats on the painted surface immediately after application is sprayed. After treating the mouthpiece 2, it is dried with warm air or the like.

The heating temperature, time, and the above-described steam pressure, steam treatment time, drying time, etc., depend on the properties of the material of cedar and fir, the required properties after processing, and the application of the polyurethane resin is performed under the conditions described above. It may be done in range.

In the present invention, when the top of the kamaboko board is treated, the urethane resin adheres to the vicinity of the knot without penetrating deeply into the pipe and closes the pipe. Therefore, the kamaboko board was treated with silicon resin or its contents. As in the case, the generation of bubbles in the kamaboko is prevented.

Since polyurethane resin does not easily penetrate deep into the wood conduit and does not swell even when dried, cracking of the mouth of the kamaboko board does not occur when the top of the kamaboko board is treated with polyurethane resin. In addition, when the top of the kamaboko board is treated with a polyurethane resin, even when the kamaboko board is stocked over a long period of time, for example, about 3 to 10 months, no cracks are generated in the knot.

As described above, in the present invention, the cedar and fir are treated with water vapor and the top of the kamaboko board is treated with polyurethane resin, so that generation of bubbles in the kamaboko and adhesion of the scent of bonito to the kamaboko are prevented. Moreover, even when the kamaboko board is stocked for a long period of time, no cracks are generated in the butt.

In the present invention, polyurethane resin is applied to both ends of the cut surface of the kamaboko board, treated after being sprayed or infiltrated, and then dried to prevent the polyurethane resin from hardening and air or liquid from the conduit from entering. . The present invention will be described below based on the illustrated embodiments.

Next, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, steam treatment is appropriately performed with steam at 120 ° C. while a cedar board, which is a material of the kamaboko board to be processed, is placed.

Heating with steam was performed during the processing of the kamaboko plate as shown in FIG. In addition, when heating, it heat-processed with water vapor | steam for 10 hours at the temperature of the range of about 120 degreeC at the time of pressurization with water vapor | steam. When the steam heating was completed, the steam treatment was stopped, the temperature was gradually lowered, and drying was performed at 100 ° C. to 60 ° C.

  1 part by weight of a polyurethane resin emulsion having a molecular weight of 5000 and 3 parts by weight of water were mixed into the mouth of the kamaboko board obtained above. This mixture was applied by brush to both sides of 2 parts of the kamaboko board 1 at the rate of 15 m 2 in the 1 L of this liquid. The plate was gradually lowered from 100 ° C. with a dryer and then applied at 60 ° C. for 5 hours. After treating the end 2, it was dried with warm air or the like.

When fish paste was placed on the resulting kamaboko board and kamaboko with a board was used, there were no bubbles and no woody peculiar smell. Also, the plate itself did not change after being stored in May.

Next, an embodiment will be described with reference to FIGS. 2A and 2B of the accompanying drawings. In the present invention, (A) of FIG. 2 is a detailed view of a gutter plate. The pipe 1 exists vertically and horizontally in the wood. There is also a conduit entrance at the end of the slab, and there is a conduit outlet 2 on the plate surface. Usually, when firewood is put on the plate and heat-treated, the scents in the conduit add odors and bubbles inside Is to generate bubbles in the bag.

On the other hand, when the timber timber was treated with water vapor, it was possible to remove the scent from the inside of the conduit and eliminate the scent. Thereafter, the water vapor was cut off, dried and lowered to near 60 ° C., so that the moisture of the wood was reduced to 10% or less. In this state, the wood mouth was treated with a polyurethane resin emulsion on the wood mouth. In processing the top of the kamaboko board, as shown in FIG. 2 (B), an emulsion was applied to the knot 5 of the lumber, which is the material of the kamaboko board, to completely block the knot.

As an example, 1 part by weight of a polyurethane resin emulsion and 4 parts by weight of water were mixed, and this mixture was applied by brush to the end 6 to use an amount sufficient to block the conduit. Therefore, the amount used varied depending on the thickness and number of conduits. Thus, after treating the lip 6 with the polyurethane resin emulsion, it was dried with hot air at about 100 ° C. for about 2 minutes to obtain a treated lip.
When fish paste was placed on the resulting kamaboko board and kamaboko with a board was used, there were no bubbles and no woody peculiar smell. Also, the plate itself did not change after 6 months of storage.

As shown in FIG. 1, an appropriate steam treatment is performed with steam at 13 ° C. in a state where a kamaboko board material to be processed, for example, a fir board is placed.
Heating with water vapor is performed during the processing of the kamaboko plate as shown in FIG. In the case of heating, the heat treatment was performed with water vapor at a temperature in the range of about 130 ° C. for 8 hours when pressurized with water vapor. When the steam heating was completed, the steam treatment was stopped, the temperature was gradually lowered, and drying was performed at 100 ° C. to 60 ° C.

3 parts by weight of water was mixed with 1 part by weight of a polyurethane resin emulsion having a molecular weight of 6000 at the mouth of the kamaboko board obtained above. This mixture was applied to both surfaces of 2 parts of the kamaboko board 1 using a brush at a ratio of 15 m2 to the 1 L of this liquid. The plate was gradually lowered from 100 ° C. with a dryer and then applied at 60 ° C. for 5 hours. After treating the end 2, it was dried with warm air or the like.
When fish paste was placed on the resulting kamaboko board and kamaboko with a board was used, there were no bubbles and no woody peculiar smell. Also, the plate itself did not change after being stored in May.
