Description

[Detailed explanation of the idea]

(a) Industrial application field This relates to a kamaboko board that reduces the price and improves the hygroscopicity of kamaboko. (b) Prior art and problems to be solved by the present invention In the past, in times when resources were abundant, kamaboko boards were generally manufactured using knotless high-quality wood. However, later on, in response to changes in social conditions due to the decline in resources, laminated plywood with peeled boards or veneers bonded together began to be cut into the size of kamaboko boards, but this type of Because the adhesive used to attach the items prevented the kamaboko from absorbing enough moisture, the kamaboko had a poor shelf life and became unprofitable in terms of price. Nowadays, it is expected that prices will be lowered in accordance with the demands of the times, and that excellent kamaboko boards that will keep kamaboko for a long time and that will not warp will be produced. (c) Means for solving the problem The present invention uses laminated plywood in order to meet the above requirements, but unlike conventional laminated plywood in which peeled boards or veneers are bonded together, problems occur during sawing. The end plate is processed and used as a core material, and peeled boards or veneers are polymerized and bonded to both the front and back sides of the core material, and the depth from the front veneer or veneer is approximately two-thirds of the thickness of the core material. By providing moisture absorption holes that reach the surface of the kamaboko plate, the price of the kamaboko board can be reduced, the shelf life of the kamaboko can be improved, and the kamaboko board can be prevented from warping. (d) Embodiment and operation An example of implementation will now be explained with reference to the drawings as follows. A in the figure is formed by polymerizing and adhering peeled boards or veneers of Todomatsu, spruce, etc. to both the front and back sides of a core material using the scraps generated during lumbering of Ezomatsu, Todomatsu, Japanese fir, white spruce, etc. Material board for kamaboko board. 1 is a kamaboko board made by cutting material board A to 52 mm in length and 123 mm in width, 2 is the core material of kamaboko board 1, 3 is a peeled board or veneer glued to both the front and back sides of core material 2, and 4 is a peeled board or veneer on the front side. This is a moisture absorption hole that penetrates the projecting plate 3 and is bored to a depth of approximately two-thirds of the core material 2. Since the present invention is constructed as described above, it dries a plurality of offcuts produced during sawing of Ezomatsu, Todomatsu, Japanese fir, white spruce, etc. to a moisture content of 7% or less and has a thickness of 10 mm. After applying adhesive to the side surfaces of a plurality of plate-shaped scraps that have been processed to have a rectangular cross-section, they can be joined as desired by applying pressure in the horizontal and vertical directions using a high-frequency wood bonding device and applying high-frequency waves at the same time. After forming a core material 2 with a size of ,
This material board A is cut into kamaboko boards 1 with a length of 52 mm and a width of 123 mm, and then the core material 2 is cut from the peeled board or veneer board 3 on the front side.
The product is made by drilling moisture absorption holes 4 with a depth of approximately two-thirds of the thickness of the product. In addition, the above moisture absorption hole 4
The holes are not limited to circular moisture absorption holes as shown in the drawings, but long and thin striped moisture absorption holes may be formed using a circular saw. The present invention uses the end plate produced during sawing as a core material, and penetrates the front peeled board or veneer laminated to this core material to form moisture absorption holes with a depth of approximately two-thirds of the thickness of the core material. Since the moisture absorption holes are not necessarily limited to approximately two-thirds of the thickness of the core material, the core material does not warp, and the moisture contained in the kamaboko is absorbed by the moisture absorption holes. It is possible to provide kamaboko with a long shelf life to the market at a low price. In addition, as described above, the plurality of offcuts produced during sawing are dried to a moisture content of 7% or less, processed into a rectangular cross-section with a predetermined thickness, and adhesive is applied to the side surfaces of the plurality of offcuts that have been processed. If the core material 2 of any size is formed by applying pressure in the horizontal and vertical directions using a high-frequency wood bonding device and applying high-frequency waves at the same time to form the core material 2, the core material 2 can be manufactured efficiently and the high-frequency Since the core material is sterilized by heating, it is possible to provide a sanitary kamaboko board. In addition, using Todomatsu, the size is 52 mm in length, 123 mm in width, and 12 mm in thickness, and two moisture absorption holes 4, 4 with a diameter of 6 mm and a depth of 8 mm are provided at positions that roughly divide the longitudinal center into thirds. The test results of the weight before moisture absorption of the kamaboko board according to the present invention, the weight after moisture absorption after boiling the kamaboko board for 20 minutes, and the amount of moisture absorption are shown in Table 1. The test results for the weight of the board before moisture absorption, the weight after moisture absorption after 20 minutes of boiling, and the moisture absorption amount are as shown in Table 2, so Tables 1 and 2
In order to compare the test results shown in the table, we calculated the average value of the moisture absorption rate, that is, the ratio of the amount of moisture absorbed to the weight before moisture absorption.The average value was 25.3% when the moisture absorption holes shown in Table 1 were provided. On the other hand, it was 19.6% when the moisture absorption holes shown in Table 2 were not provided, so it was confirmed that the moisture absorption properties were definitely improved by providing the moisture absorption holes. (e) Effects of the invention As described above, the invention uses the scraps generated during sawing of the kamaboko board as a core material, and adheres strips or veneers of Todomatsu, spruce, etc. to the front and back of this core material. This type of kamaboko is made of laminated plywood, and moisture absorption holes with a depth of approximately two-thirds of the core material are formed by penetrating the peeled boards on the surface of this laminated plywood, so kamaboko using this type of kamaboko board Because it dries appropriately in a short period of time, it has a long shelf life.In addition, the core material is made from scraps produced during sawing that have been processed in any way. Since the front and back sides of the kamaboko board are made of peeled boards or veneered boards, the cost of materials is greatly reduced, and the kamaboko board has a great practical effect.
