Description

Sanitary Chopping Board Using Wood

The present invention relates to a sanitary cutting board that is used together with a knife for cutting food when cooking food, and more particularly, it is hygienic through the improvement of water resistance and chemical resistance to wood as a material, and also through the improvement of surface hardness. The present invention relates to a sanitary cutting board using wood which has improved life and durability.

Chopping board is mainly used in the kitchen of general homes or restaurants, and is used to hold food ingredients when cutting them into proper size with a knife during cooking.

Such cutting boards are typically manufactured using wood or plastic materials.

Cutting boards made of plastic materials can solve problems such as corrosion and stain cracking that may occur in wooden cutting boards. However, the cutting boards replace wood cutting boards, but the appearance of the boards may deteriorate and may cause environmental hormones. There is a limit as the problem exists.

On the other hand, the cutting board made of wood according to the prior art has a form of using the wood itself cut to a suitable size without a separate surface treatment as a cutting board. Such a cutting board is not waterproof at all, and when it comes into contact with moisture generated from food ingredients or with water from the washing process of food ingredients, moisture penetrates the wood as it is, and contaminates the surface of the cutting board with stains or rot. As it can be, it is not only hygienic undesirable due to the occurrence of odor and breeding of bacteria and microorganisms, but also greatly impairs the appearance, and at the same time, the wetting and drying of the wood are repeated, and the durability is weakened, so that the cracks on the cutting board There was a problem that could be caused. Furthermore, the surface of the wood, which has a weak surface hardness, is in direct contact with the knife, which makes the surface of the wood easy to dig, thereby reducing the overall service life of the cutting board. As it is not easy and easy to remove moisture even after washing, it is vulnerable to breeding of bacteria and microorganisms and attracts pests.

As a cutting board according to the prior art for improving the above problems, after cutting the cutting board body to a suitable size, after polishing the surface, a cutting board coated with lacquer on the polished surface has been provided.

Lacquer is one of the natural resins that have been used to make various crafts, including furniture and ornaments, etc. Lacquer extracted from lacquer has good gloss, good hardness and excellent adhesive strength, The longer it is used, the brighter and brighter the properties of the light are. It is also resistant to heat and moisture, and resistant to chemicals such as acids and alkalis. It is excellent and has been used as a paint to protect high-quality wood crafts and furniture because toxic components contained in lacquer kill various bacteria and microorganisms and prevent insects.

By applying a lacquer having such a characteristic to the surface of the cutting board and providing the cutting board with a lacquer layer on the surface, the waterproof and chemical resistance is improved and hygienic. It was possible to provide cutting boards made of wood.

However, in spite of such improvement, the lacquer layer cannot be peeled off due to repeated cutting, so that the surface of the cutting board body protected by the lacquer layer has to be exposed, thus forming a lacquer layer on the surface improves durability. It is not appropriate as a fundamental measure to increase the service life and provide hygienic cutting boards.

On the other hand, the natural wood, which is a raw material of the cutting board, has a ring in terms of its material characteristics. As shown in FIG. 1, the ring that is exposed on the surface of the cutting board body 10 is mainly hard and dark, which is grown in winter. It consists of a narrow high hardness portion (5) and a relatively hard, bright and wide low hardness portion (15), which is a part that grows mainly in summer. Therefore, if the lacquer layer (not shown) provided on the surface of the cutting board due to use continues to be used even after peeling off, the wear of the high hardness portion 5 forming the ring is low and the wear of the low hardness portion 15 is reduced. As the uneven wear increases, the upper surface of the cutting board main body 10 is not flat but changes in a wave shape as shown in FIG. As such, when uneven wear occurs and the upper surface of the cutting board becomes rugged, not only is it worse in hygiene, but also the food ingredients are not chopped so that the most important role cannot be performed properly. to be.

In order to solve the problems of the prior art as described above,

The present invention can prevent the unevenly damaged surface of the cutting board due to uneven wear despite the use of natural wood having a ring, the hygienic and improved service life through improved water resistance, chemical resistance and durability It aims at providing the used sanitary cutting board.

In order to achieve this,

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. For reference, the surface hardened layer 120 to be described below may be formed over the entirety of the cutting board body 110, may be formed only on the top and bottom surfaces of the cutting board body, or may be formed only on the top surface of the cutting board body. The case where only the upper surface of the cutting board main body is formed is demonstrated.

Sanitary cutting board using wood according to the present invention, as shown in Figure 3, so that the ring of the high hardness portion 105 and the low hardness portion 115 is repeated on the upper surface, and has a bumpy upper surface The low hardness portion 115 includes a cutting board body 110 which is selectively recessed, and a surface hardening layer 120 that flatly closes the upper surface. At this time, the maximum depth of the low-hardness portion 115 to be concave will be about 1.5mm is appropriate. In addition, the surface hardening layer 115 may be formed to cover the entire upper surface of the cutting board main body 110, and the high hardness portion 105 and the low hardness portion, which are filled only in the concave low hardness portion 115, form a ring of natural wood. It may be formed to cover the relatively soft low hardness portion 115 of the (115). Therefore, not only the surface hardened layer 115 covers the entire upper surface of the cutting board body 110 but also the low hardness even if the surface hardened layer 120 is formed only in the low hardness portion 115 of the upper surface of the cutting board body 110. The surface on the part 115 also has a high hardness similar to the surface of the high hardness part 105.

Specifically, the surface hardened layer 120 is made of a lacquer mixture containing lacquer, ocher powder and charcoal powder, and is filled in the low hardness portion 115 concave as described above, as well as the upper side of the cutting board body 110. The top surface of the cutting board body 110 is flattened by covering the entire surface. At this time, the lacquer mixture basically contains the lacquer liquid, but may include both ocher powder and charcoal powder, or may include only one of them.

The weight ratio of the lacquer in the lacquer mixture is preferably selected within the range of 1/3 to 2/3. The reason is that if the weight ratio of the lacquer liquid exceeds the above-mentioned range, the strength is weakened after the lacquer mixture is solidified, and conversely, if the weight ratio of the lacquer liquid is not within the above-mentioned range, the cohesive force may be weakened after the lacquer mixture is solidified and may be broken. In addition, ocher powder and charcoal powder contained in the lacquer mixture to overcome the difficulty of hardly filling the concave low-hardness portion 115 having a depth with only the lacquer, and also to provide an effect to improve the sterilization. When the ocher powder and charcoal powder forming the remainder except the lacquer mixture are both included in the lacquer mixture, the relative weight ratio between the two is preferably 1: 1.

Hereinafter, a method for producing a sanitary cutting board using wood according to the present invention as described above will be described in detail.

Figure 4 is a view showing a step-by-step state in the process of producing a sanitary cutting board using wood according to the present invention, Figure 4a is a perspective view showing a cutting board body undergoing a cutting step, Figure 4b is performed to perform an uneven polishing step 4C is a partial cross-sectional view showing a cutting board body that has undergone an uneven polishing step in a direction crossing a ring, and FIG. 4D shows a surface hardened layer on an upper surface of the cutting board body after applying a lacquer mixture step. It is a partial sectional drawing which shows the state which formed.

First, as shown in FIG. 4A, a cutting step of cutting the cutting board body 110 to a predetermined size using natural wood is performed.

Subsequently, as shown in FIG. 4B, an uneven polishing step of unevenly polishing the upper surface of the cutting board body 110 is performed. Specifically, the non-uniform polishing step does not selectively grind only the less hard part 115 which is relatively hard, but rather polishes the upper surface as a whole, but the wood of the hard part 105 and the low hardness part 115 forming a ring. Due to the material properties of the high-hardness portion 105 having a large machining resistance is to be polished a little, the low-hardness portion 115 having a small processing resistance is to be polished a lot so that the low-hardness portion 115 is deeper to be recessed. Therefore, after performing such an uneven polishing step, as shown in Figure 4c, the upper surface of the cutting board main body 110 is formed to be rugged. At this time, the maximum depth of the low hardness portion 115 is processed to about 1mm to 2mm, preferably about 1.5mm.

As a specific example, the non-uniform polishing step, as shown in Figure 4b, the cylindrical roller 125 and a plurality of abrasive hairs (135) protruding radially from the outer peripheral surface of the roller 125. It may be performed using a brush polishing means 130 comprising. That is, the brush polishing means 130 is placed in such a manner as to cross the direction of the rings on the upper surface of the cutting board main body 110 in a state of reciprocating in parallel with the direction of the rings, so as to friction with the polishing wool 135. Thereby causing the top surface to be unevenly polished. At this time, it will be possible to simply rotate the brush polishing means 130 as well as reciprocating. Thus, the abrasive hair 135, which causes friction with the upper surface of the cutting board body 110, will deeply polish the low hardness portion 115, which is a harder portion than the hard portion 105, which is a rigid portion.

Thereafter, as shown in FIG. 4D, a lacquer mixture applying step of forming a surface hardened layer 120 on the upper surface of the cutting board body 110 is performed. Specifically, in the lacquer application step, a lacquer mixture in which lacquer, ocher powder and charcoal powder are mixed may be used. The lacquer mixture is repeatedly applied to the upper surface of the cutting board body 110 a plurality of times. In particular, the lacquer liquid is not solidified unless it is in contact with air, and the application of the repetitive coating is also essential, and the drying must be performed in the process of repeatedly applying, and thus the surface hardened layer 120 in a form of gradually increasing thickness. As a result, such a surface hardened layer 120 fills the concave low hardness portion 115 and covers the entire upper surface of the cutting board body. In addition, ocher powder and charcoal powder contained in the lacquer mixture also overcomes the difficulty of filling the concave low-hardness portion 115 having a depth with only the lacquer, and also provides an effect of improving sterilization. At this time, the surface hardening layer 120 should be formed thicker than the maximum depth of the low hardness portion 115 in order to have a finished upper surface is a flat top surface.

In this state, the surface hardened layer 120 is not formed selectively on the low hardness portion 115 but is formed on the entire upper surface of the cutting board body 110 including the high hardness portion 105 and does not have an even surface. As a result, a planarization polishing step follows. Specifically, in the planarization polishing step, the upper surface of the surface hardened layer 120 is smoothed to be flat on the upper surface of the cutting board. This flattening polishing step may be performed only to the level of the surface hardened layer, so that the entire upper surface of the cutting board body may be covered with the surface hardened layer, and to the extent that the hard portion 105 is exposed. The surface hardened layer 120 may remain only in the low hardness portion 115.

Specifically, the surface hardening layer 120 formed thicker in the lacquer coating step is to be scraped off to the limit until the high hardness portion 105 is exposed. Therefore, when polished to the maximum, as shown in Figure 3, among the high hardness portion 105 and the low hardness portion 115 forming a ring with a relatively high hardness portion 105 and a solidified lacquer mixture The surface hardened layer 120 formed on the upper portion of the low hardness portion forms the upper surface of the cutting board body and is exposed to the outside. In other words, the upper surface, which holds the food ingredients when cutting, is made of a solid part as a whole.

Although the present invention has been illustrated and described in connection with specific embodiments, those skilled in the art may realize that various changes and modifications can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone can easily know.
