Description

[Technical Field]

[0001] The present invention relates to a solid ignition agent having an irregular shape, which is made by mixing paraffin wax with powdered wood. [Background technology]

[0002] Various solid fuels have been considered for starting fires and burning. For example, as described in JP 2006-22206 A (see Patent Document 1), in order to increase the heat and extend the burning time, a solid fuel base is formed into a plate-like shape by adding a binder to powder particles made of carbonized material, and multiple holes are formed through the top and bottom surfaces of the base, making it easier for flames to spread to the solid fuel part, improving ignition properties, and increasing the heat and burning time.

[0003] Furthermore, for example, Patent Publication No. 2009-120776 (see Patent Document 2) discloses a solid fuel having a layer of ignition agent on the upper surface of the solid fuel portion, and multiple holes formed through both the lower solid fuel portion and the upper ignition agent, making it easier to ignite and providing sufficient heat.

[0004] On the other hand, as for the ignition agent itself, for example, as described in JP 2020-164589 A (see Patent Document 3), a plate-shaped ignition agent containing paraffin in a base material of entangled cotton cylinder pulp and wood pulp is known. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-22206 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-120776 [Patent Document 3] Japanese Patent Application Publication No. 2020-164589 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned solid fuel improves ignition ability and combustion stability after ignition, but the main innovation in improving ignition ability is the provision of through holes that allow air to pass easily, and the structure is based on the assumption that a solid fuel section is provided.

[0007] Furthermore, the above-mentioned ignition agent refers to the components of the ignition agent that allow a large flame to continue for a long time, and does not have a design with an uneven shape that does not lose its shape, and does not combine a shape that satisfies the ignition function with performance.

[0008] The present invention provides a solid ignition agent having an uneven shape that is independent of the main combustion component, unlike conventional solid fuels that aim to strengthen the firepower and extend the burning time, and that firmly maintains the uneven shape of the ignition agent while fully demonstrating its ignition function. [Means for solving the problem]

[0009] The igniter according to the present invention is an igniter having an uneven shape formed by incorporating paraffin wax into a powdered wood base material, and is characterized in that the paraffin wax and at least one of starch and gelatin are incorporated into the base material so that the mass ratio relative to the base material satisfies the relationship: base material > paraffin wax > at least one of starch and gelatin, thereby forming an igniter having an uneven shape.

[0010] The mass ratio of the paraffin wax to the base material is set to 40% by mass to less than 60% by mass, and the mass ratio of the starch to the base material is set to 20% by mass to less than 40% by mass.

[0011] The mass ratio of the paraffin wax to the base material is set to 40% by mass to less than 60% by mass, and the mass ratio of the gelatin to the base material is set to 20% by mass to less than 40% by mass.

[0012] The mass ratio to the base material contains the paraffin wax, the starch, and the gelatin, and the weight ratio of the starch and the gelatin to the base material is characterized in that the gelatin > at least one of the starch and the gelatin in the previous period.

[0013] The concavo-convex solid igniter is formed in a plate shape with a predetermined thickness, and at least one of the front and back surfaces of the plate shape has concavo-convex portions formed thereon.

[0014] The pulverization particle size G of the base material is set to 100 μm < G ≤ 500 μm.

[0015] A step of containing water with a mass ratio of 50% mass - 80% mass, the paraffin wax, and starch with respect to the base material, and stirring while heating; a pressing step of stirring the base material, the paraffin wax, and the starch with the water and forming the raw material with evaporated moisture into a predetermined mold; and then, a step of drying the formed raw material.

Advantages of the Invention

[0016] It can exhibit sufficient ignition performance and provide a concavo-convex solid igniter that is difficult to collapse in shape, so it is possible to make a mascot-designed solid igniter with a concavo-convex shape, and it becomes possible for everyone to enjoy outdoor barbecue and cooking rice.

[Figure 2] It is a perspective view regarding the press molding of a concavo-convex solid igniter according to the present invention. [Figure 3] It is a diagram showing the manufacturing process of a concavo-convex solid igniter according to the present invention.

Embodiments for Carrying Out the Invention

[0018] In Fig. 1, an embodiment of a solid igniter with a concavo-convex shape is shown. The solid igniter 10 is a solid igniter with a concavo-convex shape formed by concave portions 10a and convex portions 10b on the plate surface 10c.

[0019] The solid igniter 10 has a concavo-convex shape that designs the face of a mascot (bear).

[0020] As described above, when forming the solid igniter 10 with a mascot design, as shown in Fig. 2, the raw material 2 is placed in the mold 1 and pressed with a pressing pressure P by the pressing die 3.

[0021] Fig. 3 shows the manufacturing process of the solid igniter 10 with a concavo-convex shape. Step 1 is the generation of a base material by pulverizing wood. Step 2 is to mix water with the base material, paraffin wax, and starch so that they can be kneaded easily. Step 3 is to stir and heat the mixture of the base material, paraffin wax, starch, and water to generate the raw material 2. Step 4 is the primary drying of the raw material 2, for example, leaving it to dry for about half a day to one day. Step 5 is to mold the raw material 2 into a concavo-convex shape using the mold 1 and the pressing die 3. Step 6 is to perform secondary drying of the molded product using a dryer.

[0022] Each of the steps from Step 1 to Step 6 will be described in detail below.

[0023] In the wood pulverization process of Step 1, as for the wood, this waste wood discharged from factories and the like and utilized can be pulped and effectively utilized in some cases. However, at the manufacturing sites of furniture and woodwork products, there are also many cases where it is directly burned and treated as industrial waste. Therefore, instead of waste treatment, attention was paid to using it as a base material for an igniter that can be utilized for leisure. However, since the size of the waste wood after shaving is sparse, it is not suitable as a base material for an igniter for performing forming processing and design, so it is necessary to process it into a powder form using a pulverizer. The pulverization particle size G at this time was set to 100 micrometers < G ≤ 500 micrometers in consideration of the forming processing. Thus, any waste wood can be made into a powder and utilized as a base material.

[0024] In Step 2, the process of mixing the base material, paraffin wax, and starch, the combustion time cannot be guaranteed if the powdered waste wood is left as it is, so the mass ratio relative to the base material is base material > paraffin wax > starch, and these are mixed together. More specifically, the mass ratio relative to the base material is 40% to less than 60% by mass of the paraffin wax and 20% to less than 40% by mass of the starch, and water is added and mixed.

[0025] If the paraffin wax is less than 40% by mass, it will not burn and will not function satisfactorily as a solid ignition agent, whereas if it exceeds 60% by mass, it will have poor combustibility and will emit smoke and a foul odor.

[0026] If the starch content is less than 20% by mass, the molded plate shape cannot be maintained even after drying, and if it exceeds 40% by mass, the air gap between the mixed base material and the paraffin wax becomes small, making it difficult to burn.

[0027] In Step 3, the base material, paraffin wax, starch, and water are stirred while being heated, and the water is added to the base material in a ratio of 50% to 80% by mass and kneaded. Even if the base material is mixed with the paraffin wax, starch, and water in the container, they do not mix, and the uneven shape will not be maintained even if the material is molded in this state. Therefore, after adding the water, the materials are kneaded while being heated as needed, so that the paraffin wax melts and the water evaporates, producing raw material 2 of the fire starter.

[0028] If the water content is less than 50% by mass, the base material and paraffin wax will not mix well even after kneading. If the water content exceeds 80% by mass, the base material will be prone to separation, and the shape will be easily distorted during press molding, making it difficult to maintain hardness.

[0029] In the primary drying step of Step 4, the raw material 2 is left for a predetermined time (half a day to a day indoors). Since the hardness of the raw material 2 is weak immediately after mixing, it is dried until it becomes hard enough to withstand the pressure of the press.

[0030] In Step 5, the molding process using a mold, once the primary drying is complete, raw material 2 is placed in mold 1 and pressed from above using mold 3, as shown in Figure 2. As shown in Figure 2, the underside of mold 3 (not shown) is designed with a 1.5 to 2 mm uneven shape. Silicone spray is applied to the undersides of mold 1 and mold 3 before pressing to prevent raw material 2 from adhering to mold 1 and mold 3 after pressing, and the raw material is compressed using a press (not shown). Raw material 2 has a thickness of 5 mm and an area of ​​plate surface 10c of 4 square centimeters. The pressing pressure is 3 tons, which allows the uneven shape to be formed on plate surface 10c. After compression, the molded product is removed from mold 1, resulting in solid ignition agent 10 with the uneven shape shown in Figure 1. Since the size varies depending on the type of ignition agent, when the surface area of ​​plate surface 10c is 3 to 15 square centimeters and the thickness is 4 to 20 mm, the pressing pressure should be 1 to 5 tons.

[0031] In the secondary drying process of Step 6, after the above process, in order to increase the hardness of solid igniter 10, after molding, hot air is blown in a dryer to dry for several hours until all moisture is removed. When it is completely dried, solid igniter 10 with the uneven shape shown in Figure 1 is completed.

[0032] The uneven shape makes it possible to create a solid fire starter 10 with a mascot design, and the solid fire starter 10 with sufficient ignition function can be used by anyone to start a fire for outdoor barbecues or cooking rice.

[0033] The starch in this embodiment refers to potato starch or wheat flour, and any material containing a starch component is applicable. Gelatin may be used instead of starch, or both starch and gelatin may be mixed. In this case, the weight ratio is gelatin > starch. While the starch is mixed in Step 2 of Figure 3, gelatin or both starch and gelatin may be mixed as described above.

[0034] When gelatin is used instead of starch, the mass ratio relative to the base material is base material > paraffin wax > gelatin, and they are mixed together. Specifically, the mass ratio relative to the base material is 40% to less than 60% by mass of the paraffin wax and 10% to less than 20% by mass of the gelatin, and water is added and mixed.

[0035] Furthermore, between Step 3 and Step 4, once the water, the paraffin wax, and the starch have been mixed with the base material, raw material 2 may be divided into multiple pieces and transferred to a pallet before solidifying. This allows for uniform weight distribution of the product.

[0036] Table 1 shows the ignition and combustion properties of paraffin wax and starch on powdered wood substrates. ◯ indicates a suitable value, × indicates an inappropriate value, and △ indicates a value that cannot be considered suitable. This is also true for Tables 2 to 4, which will be explained next. Table 2 shows the dry solid fire starter hardness (resistance to deformation) of paraffin wax and starch on a powdered wood substrate. Table 3 shows the ignition and combustion properties of paraffin wax and gelatin on powdered wood substrates. Table 4 shows the hardness (resistance to deformation) of dried solid fire starters of paraffin wax and gelatin on a powdered wood substrate.

[0038] [Table 2] Hardness (resistance to deformation)

[0039] [Table 3] Ignition and Combustion

[0040] [Table 4] Hardness (resistance to deformation)

[0041] Regarding the mass ratio of paraffin wax to starch relative to the base material, in order to achieve both ignition ability and hardness, it can be understood that the appropriate mass ratio range is one where the circles in Tables 1 and 2 overlap, with 40% to less than 60% paraffin wax and 20% to less than 40% starch. Regarding the mass ratio of paraffin wax to gelatin relative to the base material, in order to achieve both ignition ability and hardness, it can be understood that the appropriate mass ratio range is one where the circles in Tables 3 and 4 overlap, with paraffin wax being 40% to less than 60% by mass and gelatin being 10% to less than 20% by mass.

[0042] As described above, examples have been shown in which paraffin wax and starch, or paraffin wax and gelatin, are mixed with a powdered wood substrate. However, in addition to gelatin, starch may be mixed in an amount of 10% by mass or less relative to the substrate to further prevent deformation. By mixing these ingredients and setting the weight ratio of water before mixing as shown below, it is possible to achieve both ignition and combustion properties and hardness by heating and mixing, so that a solid ignition agent with an uneven shape can be formed, making it possible to create a mascot design.

[0043] The mass of water relative to the wood substrate is set to 50% to 80% by mass, by mixing the substrate, paraffin wax, and either starch or gelatin, or both starch and gelatin, and then heating and stirring. To facilitate evaporation of the water, the mass of water relative to the substrate is set to 50% to 80% by mass.

[0044] As described above, this embodiment provides a solid ignition agent that exhibits sufficient ignition performance and has an uneven shape that is resistant to deformation.The uneven shape makes it possible to create a solid ignition agent with a mascot design, allowing everyone to enjoy outdoor barbecues and rice cooking. [Industrial Applicability]

[0045] The present invention allows everyone to enjoy outdoor activities and cooking rice as an uneven solid fire starter that maintains the shape of various molded articles, such as for barbecues, camp cooking, and tabletop stoves. [Explanation of symbols]
