Description

Technology Field

[0001] The present invention relates to a modular colorimetric tray, and more specifically, to a modular colorimetric tray designed with a double-sided structure to accurately measure the quality and color of green coffee beans, roasted beans, ground coffee, etc., which can be selectively used according to the shape and size of the sample to be measured, and which includes an auxiliary tray system for organizing samples to enhance user convenience and measurement accuracy. Background Technology

[0003] In the coffee industry, measuring the quality and color of green, roasted, and ground coffee serves as a critical factor in product consistency and quality control. Traditional methods for measuring coffee color have primarily involved visual inspection or placing coffee in a single-structure tray and observing it using measuring instruments.

[0005] Conventional colorimetric trays are designed with a single structure, failing to provide an optimized measurement environment for various types of coffee samples (green beans, roasted beans, and ground coffee). In other words, even for the same coffee, it was difficult to obtain consistent data depending on the condition of the sample (grind size, particle size, density, etc.). Furthermore, sample loss and contamination issues during the measurement process have been pointed out as limitations of existing technology. Particularly in the case of ground coffee, unnecessary waste could occur due to samples spilling out of the tray or during the cleanup of remaining samples after measurement; this often led not only to economic losses but also to contamination of the measurement environment.

[0007] In addition, existing colorimetric trays are generally optimized for only one sample type, making it difficult to flexibly measure the various stages of coffee condition (green beans, roasted beans, ground coffee) that occur during the roasting process, and there was the inconvenience of having to replace a different tray for each measurement.

[0009] Korean Registered Patent No. 10-1364986 is an invention relating to a tray for measuring the roasting degree of coffee, in which the inner plate and the outer plate are formed as a single unit to prevent coffee powder from overflowing to the outside, and the upper surface of the partition wall of the inner plate is in close contact with the tube of the colorimeter to enable accurate color measurement without interference from external light.

[0011] However, the aforementioned prior art has a fatal limitation as it is designed with an integrated structure. Above all, this integrated structure suffers from a fundamental problem in that it cannot provide an optimized measurement environment depending on the form of the coffee sample to be measured (green beans, roasted beans, ground coffee). Since each form of coffee has significantly different physical characteristics (size, density, particle size, etc.), it is impossible to accurately measure all forms of samples using a single fixed, integrated tray. While optimal measurement results can be obtained for ground coffee using a shallow-depth tray, a deeper tray is essential for roasted or green beans.

[0013] Furthermore, this integrated structure fundamentally prevents the use of both sides of the tray, resulting in the inefficiency of inevitably requiring multiple trays for measuring various samples. This leads not only to increased equipment costs but also to the hassle of storage and management, significantly degrading the user experience. A more serious issue is that the integrated design makes it impossible to implement auxiliary systems for organizing and recycling samples. Consequently, a significant amount of sample is lost during the measurement process, resulting in substantial economic losses when using expensive coffee samples. Additionally, contamination of the measurement environment caused by spilled samples significantly reduces measurement accuracy.

[0015] Therefore, there is a need to develop a modular colorimetric tray that can provide an optimized measurement environment according to the shape of samples such as coffee using a single tray, minimize sample loss, and enable consistent quality control through accurate colorimetric measurement. The problem to be solved

[0017] The present invention aims to solve the aforementioned problems by providing a modular colorimetric measuring tray that offers an optimized measurement environment according to the shape of the sample, minimizes sample loss, and enables consistent quality control through accurate colorimetric measurement.

[0018] The problems to be solved by the present invention are not limited to those mentioned above, and other problems not mentioned can be clearly understood by those skilled in the art to which the present invention belongs from the description below. means of solving the problem

[0020] A modular colorimetric tray according to an embodiment of the present invention for achieving the above technical objective comprises, in a modular colorimetric tray for measuring the quality and color of a sample, a measuring container formed by a first bottom portion having a space for holding a sample and a first partition formed around the perimeter of the first bottom portion, and an auxiliary tray formed by a second bottom portion having a guide slot formed therein and a second partition formed around the perimeter of the second bottom portion, wherein the measuring container is detachably coupled to the auxiliary tray.

[0021] In addition, the measuring container has an 'H'-shaped cross-section, and when the upper surface of the first bottom part is positioned so as to face upward, a first space is formed, and when the lower surface of the first bottom part is positioned so as to face upward, a second space is formed, and the depth of the first space is deeper than the depth of the second space.

[0022] In addition, the auxiliary tray is characterized by having at least one opening formed in the second partition wall, so that a sample overflowing from the measuring container is collected in the second bottom portion and discharged through the opening.

[0023] In addition, the measuring container is characterized by the first space and the second space being formed at different depths, which are selectively used depending on the particle size of the sample to be measured, and having a low-reflection surface treatment to improve the accuracy of the color measurement of the sample.

[0024] Additionally, the guide slot comprises a first guide slot formed to correspond to the circumference of the first bulkhead and a second guide slot extending from the first guide slot and formed at an angle toward the opening, wherein the first guide slot is formed horizontally with respect to the ground so as to be horizontal when the measuring container is mounted, and the second guide slot guides the sample to move toward the opening.

[0025] In addition, the combination of the measuring container and the auxiliary tray is characterized by the formation of a plurality of protrusions extending outward at predetermined intervals in the circumferential direction on the lower outer surface of the first partition, and an L-shaped guide groove formed on the inner surface of the guide slot at a position corresponding to the protrusions, such that when the measuring container is inserted into the auxiliary tray so that the protrusions and the guide grooves correspond and then rotated clockwise, the protrusions move along the guide grooves and are fixed.

[0026] In addition, the guide groove is characterized by having a plurality of uneven sections formed along the path where the projection moves horizontally.

[0027] In addition, the guide groove is characterized by having a recess formed at the end of the path where the projection moves horizontally, for the projection to be fitted and coupled thereto. Effects of the invention

[0029] The modular colorimetric tray according to the present invention is configured with a modular design that considers user convenience, allowing for easy cleaning and storage after measurement.

[0030] In addition, since both sides of the measuring container can be used, measurements can be taken by selecting the appropriate side depending on the size and shape of the sample to be measured.

[0031] In addition, sample loss can be minimized through an auxiliary tray designed to prevent samples from scattering and to easily collect and reuse falling samples, thereby enabling more economical and hygienic measurements.

[0032] In addition, the sample can be treated with an anti-reflective surface to improve the accuracy of color measurement.

[0033] Furthermore, it can be applied not only to coffee but also to the color evaluation of various foods such as cocoa beans, grains, tea, and baking ingredients, and further to the fields of chemistry, materials engineering, precision measuring instruments, and various laboratory equipment.

[0034] However, the effects of the present invention are not limited to the effects described above, and unmentioned effects will be clearly understood by those skilled in the art from this specification and the attached drawings. Brief explanation of the drawing

However, the concept of the present invention is not limited to the presented embodiments. Those skilled in the art who understand the concept of the present invention may easily propose other inventions that are inferior or other embodiments included within the scope of the concept of the present invention by adding, changing, or deleting other components within the same scope of the concept, and such are also to be considered to be included within the scope of the concept of the present invention.

Singular expressions may include plural expressions unless the context clearly indicates otherwise. Throughout the specification of this invention, the term 'comprising' any component means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0040] FIG. 1 is a drawing illustrating an example of use of a modular colorimetric measuring tray according to one embodiment of the present invention.

[0042] Referring to FIG. 1, a modular colorimetric measuring tray (10) according to one embodiment of the present invention can be used to measure quality and colorimetric values ​​by placing a sample (20), such as coffee, in a measuring device (30). At this time, the modular colorimetric measuring tray (10) of the present invention is composed of a measuring container (100) and an auxiliary tray (200), and these can be combined so as to be detachably attached to each other.

[0044] The modular colorimetric tray (10) of the present invention can be utilized as an important tool for quality control of green beans, roasted beans, and ground coffee in the coffee industry. Conventional colorimetric trays were designed with a single structure and had the problem of not being able to provide an optimized measurement environment for various types of coffee samples. In particular, even for the same coffee, it was difficult to obtain consistent data depending on the condition of the measurement sample (grinding degree, particle size, density, etc.), and sample loss and contamination issues occurring during the measurement process were also pointed out as limitations of existing technology.

[0046] Here, the sample (20) is mainly intended for green coffee beans, roasted coffee beans, and ground coffee, but is not limited thereto and can be used to measure the color of various substances. For example, it can be applied to the color evaluation of various foods such as cacao beans, grains (rice, barley, wheat, etc.), tea, baking ingredients (flour, sugar, etc.), and spices. It can also be used for color analysis in various fields such as chemical substances, pigments, dyes, soil samples, and minerals in powder form. In particular, it can be effectively used to monitor color changes in substances that require roasting or drying processes, and can be used for objective color evaluation of various samples in research and quality control fields.

[0048] Additionally, the measuring device (30) is a device for measuring the color of a sample (20) contained in a modular colorimetric measuring tray (10), and is designed to be compatible with various types of colorimeters or spectrophotometers. The measuring device (30) generally measures color quantitatively by irradiating light onto the surface of the sample and analyzing the spectrum of the reflected light. The tray (10) of the present invention is universally compatible with measuring devices of various brands and models, and in particular, the size and shape of the measuring window are optimized to enable accurate color measurement. The measuring device (30) can be used in conjunction with manual or automated systems, and can improve the efficiency of quality control by linking with a digital data collection and analysis system.

[0050] Through this configuration, the modular colorimetric measuring tray (10) of the present invention is designed to provide an optimized measurement environment for samples of various shapes and sizes, minimize sample loss, and obtain accurate and consistent colorimetric measurement results. In particular, the modular design allows for easy cleaning and storage after measurement with consideration for user convenience, and enhances usability in various measurement environments.

[0052] Below, the specific configuration of the modular colorimetric measuring tray (10) of the present invention will be described in detail.

[0054] FIG. 2 is an exploded perspective view of a modular colorimetric measuring tray according to one embodiment of the present invention, and FIG. 3 is an assembled perspective view of a modular colorimetric measuring tray according to one embodiment of the present invention.

[0056] Referring to FIGS. 2 and 3, a modular colorimetric measuring tray (10) according to one embodiment of the present invention may include a measuring container (100) comprising a first bottom portion (110) in which a space for holding a sample (20) is formed and a first partition (120) formed around the perimeter of the first bottom portion (110), and an auxiliary tray (200) comprising a second bottom portion (210) in which a guide slot (211) is formed and which is fitted together with the first partition (120) and a second partition (220) formed around the perimeter of the second bottom portion (210). At this time, the measuring container (100) may be detachably coupled to the auxiliary tray (200).

[0058] The above measuring container (100) is used to hold samples (20) for measuring the quality and color of various samples (20), including green coffee beans, roasted beans, and ground coffee, and may be composed of a first bottom part (110) and a first partition (120). The first bottom part (110) is the part where the sample is placed directly, and its cross-section is designed in an 'H' shape so that it can be used on both sides.

[0059] For example, the measuring container (100) has an 'H' shape cross-section, and when the upper surface of the first bottom part (110) is positioned so that it faces upward, a first space (S100) is formed, and when the lower surface of the first bottom part (110) is positioned so that it faces upward, a second space (S200) is formed, and the depth (D100) of the first space (S100) may be deeper than the depth (D200) of the second space (S200). As a result, the first space (S100) can contain a sample (20) with relatively large particles, such as coffee beans, and the second space (S200) can contain a sample (20) in the form of powder with relatively small particles, such as ground coffee, so that various samples can be compatible with a single tray (10).

[0060] For example, the shape of the first bottom portion (110) is configured to be circular, but is not limited thereto and can be configured in various shapes such as elliptical, square, polygonal, or irregular shapes. These various shapes can be selected by optimizing according to the characteristics of the sample to be measured or the shape of the measuring instrument, and in particular, can be designed to match the size of the measuring window of a specific measuring instrument.

[0061] For example, the first partition (120) is formed around the perimeter of the first bottom portion (110) and serves to prevent the sample (20) from flowing down from the first bottom portion (110). At this time, the first partition (120) may be configured as a straight vertical wall, for example, but is not limited thereto and can be implemented in various forms. For example, the first partition (120) may be configured in a concave shape inwardly or a convex shape outwardly, and such modifications can further improve the convenience and accuracy of measurement by ensuring even distribution of the sample. Additionally, the first partition (120) is not necessarily formed only vertically, but may be formed at a certain angle inwardly or outwardly depending on the characteristics of the sample and measurement conditions. An inclined partition can be particularly useful when measuring a fine powder-type sample that has the characteristic of flowing down easily, and can provide a more uniform measurement surface by causing the sample to gather towards the center.

[0062] For example, the measuring container (100) may be formed with the first space (S100) and the second space (S200) having different depths (D100, D200), which are selectively used depending on the particle size of the sample (20) to be measured, and may be treated with a low-reflection surface to improve the accuracy of the color measurement of the sample (20). This low-reflection surface treatment minimizes reflection or interference from external light sources that may occur during the measurement process, thereby enabling accurate measurement of the sample's original color.

[0063] For example, the above-mentioned low-reflection surface treatment may be a matte anodizing process, and the above-mentioned matte anodizing process is a main surface treatment method of the above-mentioned measuring container (100), which can improve durability and reduce light reflection by forming an electrochemical oxide film on the aluminum surface. This process forms a fine pore structure on the surface so that incident light is scattered in various directions, thereby minimizing specular reflection and increasing diffuse reflection, which enables accurate color measurement, and has the advantage of maintaining surface quality even after long-term use due to excellent wear resistance and corrosion resistance. In addition to this, various low-reflection surface treatment methods applicable to the above-mentioned measuring container (100) may be performed, such as black oxide treatment, chemical etching, micropowder coating, plasma spray coating, PVD (Physical Vapor Deposition) coating, silicon-based matte coating, and laser surface treatment. These various low-reflection surface treatment methods may be selectively applied considering the material, production cost, usage environment, and required durability of the above-mentioned measuring container (100), and if necessary, two or more methods may be applied in combination to optimize low-reflection characteristics. In the present invention, matte anodizing processing was selected as the optimal method to satisfy excellent durability, low-reflection characteristics, and food contact safety; however, as explained above, other surface treatment methods may also be applied depending on the material or usage environment of the above-mentioned measuring container (100).At this time, it is obvious that the above-mentioned low-reflection surface treatment can be applied not only to the measuring container (100) but also to the auxiliary tray (200) to be described later.

[0064] Here, black oxide treatment is a method of forming a black oxide layer on a metal surface through a chemical reaction, particularly applied to iron or stainless steel materials; this treatment is relatively inexpensive and can significantly reduce light reflection without causing almost any dimensional changes to the surface. Additionally, chemical etching is a method of finely corroding a metal surface using acidic or alkaline solutions to form an irregular uneven structure, causing light to scatter in various directions and creating a precise surface texture, which can be effective in reducing reflection. Furthermore, micropowder coating is a method of inducing light scattering by coating the surface with ultrafine powder particles, allowing for the realization of various colors and textures; in particular, powder coatings using materials such as epoxy, polyester, and acrylic can offer excellent durability and chemical resistance. Additionally, plasma spray coating is a method of spraying ceramic or metal particles onto the surface using high-temperature plasma, forming a very dense and irregular surface structure to minimize light reflection and provide high heat resistance and wear resistance. In addition, PVD (Physical Vapor Deposition) coating is a method of depositing metal or ceramic materials to an ultrafine thickness using a physical vapor deposition method in a vacuum. By coating with titanium nitride (TiN), chromium nitride (CrN), etc., it is possible to significantly improve surface hardness along with low-reflection characteristics. Furthermore, silicon-based matte coating forms a coating layer based on silicon compounds, which offers excellent durability while effectively reducing light reflection, and has the advantage of being safe to use, especially in food contact environments.In addition, laser surface treatment is a method that uses a high-power laser to form fine patterns or structures on a surface, which can increase light absorption and reduce reflection, and enable very precise control of surface texture.

[0066] The auxiliary tray (200) is used to collect a sample (20) that has overflowed or flowed out from the measuring container (100) and to stably support the measuring container (100). The auxiliary tray (200) is composed of a second bottom part (210) and a second partition (220).

[0067] For example, the second partition (220) is formed around the perimeter of the second bottom portion (210) and serves to prevent the sample (20) that overflows or flows out from the measuring container (100) from leaking out. The second partition (220) may be configured as a straight vertical wall, for example, but is not limited thereto and can be implemented in various forms. For example, the second partition (220) may be configured in a concave shape inwardly or a convex shape outwardly, and such variations can help effectively collect or process the flowed-out sample. In addition, the second partition (220) is not necessarily formed only vertically, but may be formed at a certain angle inwardly or outwardly depending on the purpose of use and the characteristics of the sample. An inclined partition can particularly guide the flowed-out sample to gather in the center or a specific direction, thereby facilitating organization and cleaning.

[0068] For example, the auxiliary tray (200) has at least one opening (221) formed in the second partition (220), so that the sample (20) overflowing from the measuring container (100) is collected in the second bottom portion (210) and can be easily discharged through the opening (221). The opening (221) serves as a cleaning hole, allowing for the efficient collection or removal of samples remaining after measurement. The location, size, and number of the openings (221) can be adjusted in various ways depending on the usage environment and the characteristics of the sample. In particular, when handling samples in the form of fine powder that frequently flow out, multiple openings can be strategically placed to increase cleaning efficiency. However, this is not limited to this, and various modifications are possible to a level obvious to a person skilled in the art; for example, the opening (221) may be absent.

[0069] For example, the second bottom portion (210) is a base structure on which the measuring container (100) is placed, and the second bottom portion (210) may have a guide slot (211) formed therein that is fitted together with the first partition (120) of the measuring container (100). At this time, the guide slot (211) may be a slot that guides the attachment and detachment of the measuring container (100) and guides a path for discharging the sample (20) that has overflowed from the measuring container (100), and may be in a shape that is recessed downward from the second bottom portion (210).

[0070] For example, the guide slot (211) is composed of a first guide slot (212) formed to correspond to the circumference of the first bulkhead (120) and a second guide slot (213) formed extending from the first guide slot (212). The first guide slot (212) and the second guide slot (213) may be formed horizontally with respect to the ground, but are not limited thereto and can be modified in various ways that are obvious to a person skilled in the art.

[0071] For example, the guide slot (211) is formed with a first guide slot (212) formed to correspond to the circumference of the first partition (120) and a second guide slot (213) extending from the first guide slot (212) and formed at an angle toward the opening (221), wherein the first guide slot (212) is formed horizontally with respect to the ground so as to be horizontal when the measuring container (100) is mounted, and the second guide slot (212) can guide the sample (20) to move toward the opening (221).

[0072] For example, the shape of the second bottom part (210) is configured as a square, but is not limited thereto and can be configured in various shapes such as a circle, ellipse, polygon, or irregular shape. These various shapes can be selected by optimizing according to the usage environment or the characteristics of the sample to be measured, and can be designed with consideration for the efficiency of the workspace or user convenience.

[0074] Additionally, the measuring container (100) and the auxiliary tray (200) may be fixed by being fitted together or placed in a non-fixed state with the measuring container (100) placed on top, but are not limited thereto and may be modified in various ways that are obvious to a person skilled in the art. Below, we will describe an example in which the measuring container (100) and the auxiliary tray (200) are fixed.

[0076] FIG. 4 is a diagram illustrating the coupling mechanism between the measuring container of a modular colorimetric measuring tray and the auxiliary tray according to one embodiment of the present invention.

[0078] Referring to FIG. 4, the combination of the measuring container (100) and the auxiliary tray (200) is formed such that a plurality of protrusions (121) are formed on the lower outer surface of the first partition (120) at a predetermined interval in the circumferential direction, and an L-shaped guide groove (214) is formed on the inner surface of the guide slot (211) at a position corresponding to the protrusions (121). When the measuring container (100) is inserted into the auxiliary tray (200) and rotated clockwise so that the protrusions (121) and the guide groove (214) correspond, the protrusions (121) can move along the guide groove (214) and be fixed.

[0079] At this time, the guide groove (214) may have a plurality of uneven parts (215) formed along the path where the projection (121) moves horizontally, and a recess (216) may be formed at the end of the path where the projection (121) moves horizontally to be fitted and coupled with the projection (121).

[0080] Specifically, a plurality of protrusions (121) protruding outward at predetermined intervals in the circumferential direction may be formed on the lower outer surface of the first partition (120) of the measuring container (100), and an L-shaped guide groove (214) may be formed on the inner surface of the guide slot (211) of the auxiliary tray (200) at a position corresponding to the protrusions (121). This structure is intended to provide the effect of stably fixing the measuring container (100) to the auxiliary tray (200). When a user inserts the measuring container (100) into the auxiliary tray (200) and rotates it clockwise, the protrusions (121) move along the guide groove (214) and are fixed. During this process, the first guide slot (212) is formed to be horizontal with respect to the ground, thereby ensuring that the measuring container (100) is fixed in an accurately horizontal state. This is a very important factor in the accuracy of color measurement, as it can minimize measurement errors that may occur when the measuring container (100) is tilted. In particular, when measuring samples in the form of liquid or fine powder, a perfectly horizontal state may be essential for obtaining more accurate measurement results by ensuring that the sample surface is evenly distributed.

[0081] For example, the L-shaped guide groove (214) does not necessarily need to be formed at an exact 90-degree angle, and the vertical and horizontal parts may be modified to form a predetermined angle. In particular, the horizontal part may be formed at a slight incline to guide the projection (121) to naturally move toward the end of the guide groove (214). This inclined structure makes the joining process smoother and allows the user to fix the measuring container (100) in the correct position with minimal force.

[0082] At this time, a plurality of protrusions (215) are formed along the guide groove (214) to provide a haptic response when the measuring container (100) is rotated to join. The protrusions (215) generate tactile feedback as the protrusion (121) moves along the guide groove (214), allowing the user to detect the progress of joining without directly checking with their eyes. For example, a small vibration or click sensation may be felt whenever the protrusion (121) passes through the protrusions (215), allowing for an intuitive understanding of how much joining has been done. This can help increase work efficiency in professional environments such as laboratories and prevent sample loss or measurement errors caused by incorrect joining. At this time, the number, spacing, and height of the protrusions (215) can be designed to optimize the user experience and can be adjusted as needed to provide a softer joining sensation or clearer feedback.

[0083] Additionally, a recess (216) for fitting the projection (121) may be formed at the end of the guide groove (214). When the projection (121) moves along the guide groove (214) and reaches the recess (216), tactile feedback is stopped, immediately notifying the user that the fitting is complete. This recess (216) serves not only to indicate the completion of the fitting but also to fix the measuring container (100) in an accurate position. In particular, the depth and shape of the recess (216) are designed so that the projection (121) fits perfectly, ensuring that the measuring container (100) maintains perfect horizontal alignment on the auxiliary tray (200). This precise horizontal alignment ensures that the sample surface is uniformly illuminated during color measurement, thereby significantly improving the accuracy and reproducibility of the measurement results. In addition, the above-mentioned recess (216) can prevent the measuring container (100) from accidentally rotating or detaching during use, thereby providing a stable measuring environment.

[0084] Through this specialized coupling mechanism, the measuring container (100) and the auxiliary tray (200) can be combined easily and accurately, and the user can easily check the combined state through tactile feedback. In addition, it is fixed in a perfectly horizontal state, allowing for accurate color measurement, and can maintain stability during use, thereby obtaining reliable measurement results in a professional environment.

[0086] In order to more clearly express the technical concept of the present invention, the attached drawings briefly depict or omit configurations that are unrelated to or have little relevance to the technical concept of the present invention.

[0088] Although the structure and features of the present invention have been described above based on embodiments according to the present invention, the present invention is not limited thereto, and it is obvious to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention; therefore, it is noted that such changes or modifications fall within the scope of the appended claims.
