Description

coffee bean cutter

[0001] The present invention relates to a cutting machine for separating center cuts and husks from coffee beans.

[0002] More specifically, the present invention relates to a coffee bean cutting machine that cuts the center cut and the skin that are vertically cut in the center of coffee beans during the process of passing through a cutting roller, and collects and removes only the cut skin and the center cut in a separating section, thereby obtaining pure coffee beans from which the skin and the center cut have been removed.

[0003] In general, coffee beans are composed of a husk, a fibrous cell membrane formed in a honeycomb structure inside the husk, and coffee particles inside the cell membrane. The husk not only has no nutritional value, but also absorbs coffee fat (oil), reducing the unique flavor of the coffee beans. In addition, unnecessary compounds are created by the heat generated during grinding by fusing or combining with the cell membrane and coffee particles, and the unique flavor of the coffee beans due to the coffee fat is further reduced by the compounds, and there is a problem of causing impurities in the coffee.

[0004] In addition, during the process of grinding coffee beans, the cell membrane made of fiber is forcibly destroyed, and the heat generated during grinding exposes impurities contained in the fiber, and when the coffee particles are not protected by the cells, the heat burns the coffee fat, causing a problem of carbonization and a burnt taste.

[0005] For example, when coffee powder made by grinding roasted coffee beans is extracted in the espresso method, or dripped using a dripper, or coffee powder made by grinding coffee beans and drinking it by mixing it with water, there is a limit to producing the deep and rich flavor of coffee because the heat generated during the grinding process of roasted coffee beans is not maintained.

[0006] To explain further, conventional coffee powder is usually made by finely grinding coffee beans to a size of 0.2 to 1 mm during the process of roasting and then grinding the coffee beans. Therefore, a lot of heat is generated during the grinding process, and as a result, there is a problem in that the original flavor of the roasted coffee beans is deteriorated by the heat.

[0007] Accordingly, as a prior art to solve the above-mentioned problems, a coffee bean grinder device was disclosed in Korean Patent Publication No. 10-2068124.

[0008] Conventional coffee bean grinder devices have the advantage of easily obtaining coffee bean powder of a desired particle size by grinding the inserted coffee beans using a grinding blade.

[0009] However, as described above, the conventional coffee bean grinder device has a problem in that the heat generated when the coffee beans are finely ground causes the inner skin to fuse or combine with the cell membrane and coffee particles, making it difficult to smoothly separate the coffee beans and the inner skin, and a large amount of inner skin and center cut are still included in the ground coffee beans, which reduces the coffee's unique flavor due to the impurities and burnt taste of the coffee.

[0010] Furthermore, in the conventional coffee bean grinder device, the center cut and the shell of the coffee bean are not separated during the process of grinding the coffee bean, but only ground. Therefore, when the coffee is extracted, the ground center cut and shell are mixed, and it is difficult to extract a rich and delicious coffee due to impurities.

[0011] Furthermore, since it is not easy to separate the center cut from the coffee beans, the center cut that remains as fine powder sticks to the coffee beans during the roasting process and burns, which causes a negative charring effect. To prevent this, if medium roasting is used, there is a problem in that impurities such as hay and grassy flavors appear too strongly.

[0012] The present invention has been devised to solve the above problems, and the problem to be solved by the present invention is to provide a coffee bean cutting machine that can obtain pure coffee beans with the husk and center cut removed by cutting the center cut and husk that are vertically cut in the center of the coffee bean during the process of passing through the cutting roller, and collecting and removing only the cut husk and center cut in a separating section.

[0013] In addition, another problem to be solved by the present invention is to provide a coffee bean cutting machine in which coffee beans are cut by passing between a pair of cutting rollers, wherein the first cutting roller, which is one of the pair of cutting rollers, is formed in a horizontal shape with cutting teeth formed in the longitudinal direction of the long axis, and the other second cutting roller is formed in a vertical shape with cutting teeth formed in a diagonal shape or along the direction of rotation, thereby easily cutting the skin and center cut from the coffee beans.

[0014] In addition, another problem to be solved by the present invention is to provide a coffee bean cutting machine capable of obtaining pure coffee beans by supplying wind through a blower fan to the inner housing of the separation unit and sucking it through the dust collecting unit during the process in which the cut pure coffee beans, skins, and center cuts pass through a cyclone and then pass through a separation unit and a dust collecting unit, thereby effectively collecting and removing not only the cut skins and center cuts from the coffee beans but also foreign substances such as fine powder.

[0015] In order to solve the above problem, the present invention provides a coffee bean cutting machine comprising: a cutting unit that cuts coffee beans to separate them into pure beans, husks, and center cuts; a cyclone that sucks in foreign substances; a separation unit that supplies wind into the housing when pure beans, husks, and center cuts are transferred from the cyclone to the housing to collect the husks and center cuts and discharge only pure beans; and a case that accommodates pure beans discharged from the separation unit, thereby solving the technical problem.

[0016] The present invention has a remarkable effect of being able to obtain pure coffee beans with the husk and center cut removed by cutting the center cut and husk that are vertically cut in the center of coffee beans during the process of passing through a cutting roller, and collecting and removing only the cut husk and center cut in a separating section.

[0017] In addition, the present invention has a remarkable effect of making it easy to cut the skin and center cut from the coffee beans by passing the coffee beans between a pair of cutting rollers, wherein the first cutting roller, one of the pair of cutting rollers, has cutting teeth formed in a horizontal shape in the longitudinal direction of the longitudinal axis, and the other, the second cutting roller, has cutting teeth formed in a vertical shape in a diagonal shape or along the direction of rotation.

[0018] In addition, the present invention has a remarkable effect of obtaining pure coffee beans by supplying wind through a blower fan to the inner housing of the separation unit and sucking it through the dust collecting unit during the process in which the cut pure coffee beans, skins, and center cuts pass through the cyclone and then pass through the separation unit and dust collecting unit, thereby effectively collecting and removing not only the cut skins and center cuts from the coffee beans but also foreign substances such as fine powder.

[0044] Advantages and features of embodiments of the present invention, and methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

[0045] In describing embodiments of the present invention, if a detailed description of a known function or configuration is judged to unnecessarily obscure the gist of the present invention, such detailed description will be omitted. In addition, terms or words used in this specification and claims are terms defined in consideration of their functions in the embodiments of the present invention, and should not be interpreted as limited to their typical or dictionary meanings. Based on the principle that the inventor can appropriately define the concept of a term to best explain his or her invention, they should be interpreted as meanings and concepts that are consistent with the technical spirit of the present invention.

[0046] Therefore, it should be understood that the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, and that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0047] Hereinafter, before explaining with reference to the drawings, it is to be noted that matters that are not necessary to reveal the gist of the present invention, that is, known configurations that can be obviously added by a person skilled in the art with ordinary knowledge, are not illustrated or specifically described.

[0048] First, before describing various embodiments of the present invention in detail with reference to the attached drawings, it should be noted that terms such as “front”, “back”, “left”, “right”, “up”, “down”, “up”, “down”, “horizontal”, “vertical”, “front”, “back”, “one side”, “the other side”, “inner side”, and “outer side”) of components described in the following detailed description or depicted in the drawings do not simply indicate or imply that they must have a specific direction, and the description of such directions is intended to facilitate the description of components with reference to the attached drawings.

[0049] Meanwhile, conventional coffee beans (10) are finely ground using a grinder and then extracted to produce a coffee beverage. However, when ground using the grinder, the beans are ground so finely that the shell (11) and the center cut (12) formed by a vertical groove in the center are mixed together, and when the beans are produced into a coffee beverage in this state, the coffee fat, which is an effective ingredient, is absorbed and removed by the shell (11) and the center cut (12), which causes a problem in that the unique flavor of the coffee is reduced.

[0050] Accordingly, in order to solve the above-mentioned problem, the coffee bean cutting machine according to the present invention cuts the center cut (12) and the skin (11) that are vertically cut in the center of the coffee bean (10) as the coffee bean (10) passes through the cutting roller (120, 130), and collects and removes only the cut skin (11) and the center cut (12) in the separation unit (300) after passing through the cyclone (200), thereby minimizing the generation of fine powder and obtaining pure coffee beans from which the skin (11) and the center cut (12) have been removed.

[0051] Accordingly, by making it possible to extract coffee using only pure coffee beans, impurities can be removed during extraction, providing rich and delicious coffee.

[0052] Hereinafter, a coffee bean cutter according to the present invention will be described in detail with reference to the attached drawings.

[0053] FIG. 1 is a drawing showing coffee beans in a coffee bean cutter according to the present invention, and FIG. 2 is a schematic diagram showing a coffee bean cutter according to the present invention.

[0054] First, referring to Fig. 1, the coffee bean (10) is composed of a fibrous cell membrane formed in a honeycomb structure inside the shell (11) and coffee particles formed inside the cell membrane, and includes a center cut (12) formed by a vertical groove in the center of the coffee bean (10).

[0055] That is, the coffee bean cutting machine according to the present invention cuts coffee beans (10), collects and separates the cut skin (11) and center cut (12) from the coffee beans (10) to obtain only pure coffee beans, thereby removing impurities that appear when extracting coffee containing the skin (11) and center cut (12), thereby providing rich and delicious coffee.

[0056] Furthermore, it is possible to remove the shell (11) and center cut (12) of the roasted coffee beans (10).

[0057] Here, pure coffee beans refer to a state in which the shell (11) and center cut (12) are separated from the coffee beans (10).

[0058] In order to achieve this purpose, the coffee bean cutting machine according to the present invention is described with reference to FIG. 2, and is configured to include a cutting unit (100) for cutting coffee beans (10), a cyclone (200), a separation unit (300), a dust collecting unit (340), and a case (400).

[0059] FIG. 3 is a schematic diagram showing a cutting section in a coffee bean cutting machine according to the present invention, FIG. 4 is a cross-sectional view of a first cutting roller or a second cutting roller in a coffee bean cutting machine according to the present invention, and FIG. 5 is a cross-sectional view showing another embodiment of a first cutting roller or a second cutting roller in a coffee bean cutting machine according to the present invention.

[0060] Figure 6 is a perspective view showing different shapes of the first cutting roller and the second cutting roller in the coffee bean cutting machine according to the present invention.

[0061] FIG. 7 is a perspective view showing another embodiment of a first cutting roller and a second cutting roller of different shapes in a coffee bean cutter according to the present invention.

[0062] FIG. 8 is a perspective view showing another embodiment of a first cutting roller and a second cutting roller of different shapes in a coffee bean cutter according to the present invention.

[0063] The cutting section (100) performs the function of cutting the input coffee beans (10), and as described with reference to FIG. 3, it is configured to include an input section (110), a first cutting roller (120), a second cutting roller (130), and a discharge section (140).

[0064] That is, the first cutting roller (120) and the second cutting roller (130) are configured to rotate while interlocking, and the introduced coffee beans (10) are cut while passing between the first cutting roller (120) and the second cutting roller (130).

[0065] The input section (110) is where coffee beans (10) are input, and as shown in the attached drawing, may be formed in the form of a hopper with a wide upper side and a narrow lower side.

[0066] The first cutting roller (120) is configured to rotate by a rotation axis, and is interlocked with the second cutting roller (130) described later to rotate, so that coffee beans (10) fed into the input section (110) are cut while passing between the first cutting roller (120) and the second cutting roller (130).

[0067] The second cutting roller (130) is configured to rotate by a rotation axis, and is provided to rotate while interlocked with the first cutting roller (120).

[0068] That is, the coffee bean cutting machine according to the present invention is characterized in that the coffee beans (10) are not ground in a conventional grinder manner, but are cut by passing through a first cutting roller (120) and a second cutting roller (130) to separate the shell (11) and the center cut (12) from the coffee beans (10).

[0069] To explain in detail, coffee beans (10) are not ground by a conventional grinder-type grinding blade, but are cut after cracking by passing between a pair of cutting rollers (120, 130), thereby minimizing the generation of heat during cutting, thereby allowing the peeling of the husk (11) to be smoothly performed, and allowing the center cut (12) to be easily separated along with the husk (11), so that only pure coffee beans can be obtained.

[0070] In detail, the method of passing between a pair of cutting rollers (120, 130) is based on the principle of minimizing the generation of heat by cutting after cracks are generated in the coffee beans (10), thereby minimizing the forcible destruction of the cell membrane of the coffee beans (10), minimizing the generation of impurities due to carbonization of the cell membrane by finely cutting along the honeycomb structure of the cell membrane, and obtaining the effect of allowing the enjoyment of the unique deep and rich flavor of the coffee beans (10).

[0071] In order to obtain this effect, the coffee bean cutting machine according to the present invention is provided so that the first cutting roller (120) and the second cutting roller (130) are interlocked with each other and rotate, so that the coffee beans (10) passing through the first cutting roller (120) and the second cutting roller (130) are smoothly cut, and at the same time, the shell (11) and the center cut (12) are separated from the coffee beans (10).

[0072] At this time, in order to ensure smooth cutting of the coffee beans (10), the first cutting roller (120) and the second cutting roller (130) are formed with a number of cutting teeth (131) protruding outward on the outer surface.

[0073] As one embodiment of such a cutting tooth (131), referring to FIG. 4, the outer surface may be formed so that the curved surfaces concave inward are symmetrical to each other, and the thickness (d) of the cutting tooth may be formed so that it becomes thinner as it goes outward.

[0074] That is, as the cutting teeth (131) are formed with sharp ends, they are used to cut, slice, and trim coffee beans (10) passing between the first cutting roller (120) and the second cutting roller (130).

[0075] Accordingly, the cutting teeth (131) formed on each of the first cutting roller (120) and the second cutting roller (130) cut the coffee beans (10) passing between the first cutting roller (120) and the second cutting roller (130), thereby smoothly separating the shell (11) and the center cut (12) from the coffee beans (10).

[0076] Referring to Fig. 4, a cutting tooth (131) of this type has a tooth thickness (d), a tooth height (h), and a groove width (t), and the ratio of the height (h) and the groove width (t) can be 1:n~3. Here, n means greater than 1.

[0077] Preferably, the ratio of the height (h) and the width (t) of the groove can be 1.5:2. That is, the height (h) can be approximately 1.5 mm, and the width (t) of the groove can be approximately 2 mm.

[0078] Accordingly, by making it easier to cut the coffee beans (10) during the process of cutting the coffee beans (10), the shell (11) and the center cut (12) can be separated more easily from the coffee beans (10).

[0079] Furthermore, in the process of cutting coffee beans (10) of various sizes, a first cutting roller (120) and a second cutting roller (130) having different ratios may be applied depending on the type of coffee to be extracted.

[0080] For example, in the case of extracting regular coffee using relatively large beans, the coffee beans (10) are cut using the first cutting roller (120) and the second cutting roller (130) equipped with cutting teeth (131) having a height (h) and a groove width (t) ratio of 3:6, and as another example, in the case of extracting coffee to be steeped in room temperature or cold water for a long time, such as cold brew, the coffee beans (10) can be cut using the first cutting roller (120) and the second cutting roller (130) equipped with cutting teeth (131) having a height (h) and a groove width (t) ratio of 2:3.

[0081] In addition, as another embodiment of the cutting tooth (131), as described with reference to FIG. 5, it may be formed in a form in which the outer surface is dug inward, but the thickness (t) of the dug groove may be made constant.

[0082] In this way, the cutting teeth (131) shown in Fig. 5 can be used for crushing rather than cutting and slicing coffee beans (10).

[0083] Depending on the design conditions, the cutting teeth (131) formed on one selected configuration among the first cutting roller (120) and the second cutting roller (130) may be formed in a horizontal shape that is elongated in the longitudinal direction, and the cutting teeth (131) formed on the other configuration may be formed in a vertical shape or a diagonal shape that is formed along the rotational direction.

[0084] This embodiment will be described with reference to FIG. 6. The cutting teeth (131) formed on the first cutting roller (120) may be formed in a horizontal shape that is formed long in the longitudinal direction of the long axis, and the cutting teeth (131) formed on the second cutting roller (130) may be formed in a vertical shape that is formed along the direction in which the second cutting roller (130) rotates.

[0085] In another embodiment, the cutting teeth (131) formed on the first cutting roller (120) may be formed in a horizontal shape that is elongated in the longitudinal direction, and the cutting teeth (131) formed on the second cutting roller (130) may be formed in a diagonal shape, as illustrated in FIG. 7.

[0086] In another embodiment, the cutting teeth (131) formed on the first cutting roller (120) may be formed in a horizontal shape that is formed long in the longitudinal direction of the long axis, and the cutting teeth (131) formed on the second cutting roller (130) may be formed in a grid shape in which diagonal shapes intersect each other.

[0087] Accordingly, as shown in FIGS. 6 to 8, the cutting teeth (131) formed on the first cutting roller (120) and the second cutting roller (130) are formed in a mixed form, thereby enabling the coffee beans (10) to be cut more precisely and easily.

[0088] The discharge unit (140) is provided on the lower side of the first cutting roller (120) and the second cutting roller (130) so that the pure coffee beans and shells (11) and center cuts (12) that are cut while passing through the first cutting roller (120) and the second cutting roller (130) are separated and discharged, and are transferred to the cyclone (200) described later.

[0089] At this time, the discharge unit (140) may be formed in a hopper shape in which a portion is wide at the top and narrow at the bottom so that pure coffee beans and shells (11) and center cuts (12) that have passed through the first cutting roller (120) and the second cutting roller (130) can easily be introduced, as shown in the attached drawing.

[0090] Fig. 9 is a drawing showing a gap adjustment unit in a coffee bean cutter according to the present invention.

[0091] Depending on the design conditions, the cutting section (100) may be configured to include a gap adjusting section (150) that adjusts the gap between the first cutting roller (120) and the second cutting roller (130), as described with reference to FIG. 9.

[0092] The gap adjustment unit (150) performs the function of adjusting the gap between the first cutting roller (120) and the second cutting roller (130), and can be formed in various forms.

[0093] Preferably, the first cutting roller (120) is configured to be connected to a rotation axis that allows the rotation of the second cutting roller (130), and the pair of rotation axis are connected by screw threads, so that the gap between the first cutting roller (120) and the second cutting roller (130) can be easily adjusted only by the process of rotating the handle.

[0094] Accordingly, the gap between the first cutting roller (120) and the second cutting roller (130) can be adjusted, so there is an advantage in that the size of the coffee beans (10) to be cut can be selectively adjusted.

[0095] That is, since the size of the coffee beans (10) being cut can be adjusted, the problem of generating a lot of heat, as in the conventional grinder method of finely grinding coffee beans (10), is blocked, and the cutting size of the coffee beans (10) can be freely cut to a desired size of 0.1 to 5 mm.

[0096] Furthermore, by varying the size of the pure coffee beans cut and discharged during light or heavy roasting depending on the roasting state of the coffee beans (10), a more excellent effect can be obtained. Accordingly, the coffee bean cutting machine according to the present invention can easily adjust the cutting size of the coffee beans (10) by adjusting the gap between the first cutting roller (120) and the second cutting roller (130), and further, has the advantage of being able to provide customized coffee beans for light or heavy roasting by adjusting the speed of the cutting rollers (120, 130) together.

[0097] Figure 10 is a schematic diagram showing an example in which the first cutting roller and the second cutting roller are provided in multiple layers in a coffee bean cutting machine according to the present invention.

[0098] Depending on the design conditions, the configuration including the first cutting roller (120) and the second cutting roller (130) provided in the cutting section (100) may be formed into multiple layers spaced apart from each other in the upper and lower directions.

[0099] For example, as shown in Fig. 10, a configuration including a first cutting roller (120) and a second cutting roller (130) may be configured as a pair with the upper and lower sides spaced apart.

[0100] This allows the coffee beans (10) to pass between the first cutting roller (120) and the second cutting roller (130), and since they are made up of multiple layers, they pass sequentially to cut the coffee beans (10) more finely.

[0101] Depending on the design conditions, the size of the cutting teeth (131) formed on the first cutting roller (120) and the second cutting roller (130) consisting of multiple layers may be different for each layer.

[0102] For example, a first cutting roller (120) and a second cutting roller (130) formed with cutting teeth (131) having a height (h) and a width (t) of the groove of 3:6 and a first cutting roller (120) and a second cutting roller (130) formed with cutting teeth (131) having a height (h) and a width (t) of the groove of 2:3 may be sequentially provided on the upper and lower sides.

[0103] This allows coffee beans (10) to be passed through a first cutting roller (120) and a second cutting roller (130) having large cutting teeth (131) formed thereon, and then passed through a second cutting roller (120) and a second cutting roller (130) having relatively small cutting teeth (131) formed thereon, thereby obtaining uniform coffee beans.

[0104] Additionally, the first cutting roller (120) and the second cutting roller (130) provided on each floor can be configured so that the interval between them is adjusted by the interval adjusting unit (150).

[0105] For example, by widening the gap between the first cutting roller (120) and the second cutting roller (130) formed with cutting teeth (131) having a height (h) and a width (t) of the groove of 3:6, and by adjusting the gap between the first cutting roller (120) and the second cutting roller (130) formed with cutting teeth (131) having a height (h) and a width (t) of the groove of 2:3 to be relatively narrow, the coffee beans (10) are cut, thereby obtaining more uniform beans.

[0106] The cyclone (200) performs the function of sucking up foreign substances, etc. as pure coffee beans, shells (11) and center cuts (12) cut from the cutting section (100) pass through.

[0107] This cyclone (200) is equipped with a number of rotating blades inside through a cyclone vacuum design, a motor that rotates these rotating blades, and a rotary valve at the bottom to discharge pure coffee beans and shells (11) and center cuts (12) from which foreign substances have been removed.

[0108] Here, the cyclone vacuum design is a means for providing centrifugal force for amplifying the air as it passes through the sieve during the process in which pure coffee beans and shells (11) and center cuts (12) are introduced together with air, and can prevent foreign substances such as dust in the air from being absorbed into the coffee beans, and further, foreign substances can be separately sucked in and captured.

[0109] Fig. 11 is a side cross-sectional view showing a separation part in a coffee bean cutter according to the present invention.

[0110] The separation unit (300) is configured to include a housing (310), a stepped conveying plate (320), a blower fan (330), and a dust collecting unit (340), which performs the function of supplying wind to the inside of the housing (310) so that only pure coffee beans and shells (11) and center cuts (12) transferred from a cyclone (200) are discharged.

[0111] The housing (310) provides a space for receiving pure coffee beans, shells (11) and center cuts (12) transferred from the cyclone (200), and is connected to the rotary valve of the cyclone (200).

[0112] That is, pure coffee beans and shells (11) and center cuts (12) with foreign substances removed from the cyclone (200) are transferred into the housing (310) under the control of the rotary valve.

[0113] At this time, the housing (310) is not shown in the drawing, but may be formed in the shape of a box with an empty interior, but with a central cross-section having a number of angles, such as a circle, square, or pentagon.

[0114] The stepped conveyor plate (320) is provided in a plurality of layers spaced apart from each other upward and downward inside the housing (310), and is formed in a stepped shape so that the length protruding to one side gradually increases as it goes downward.

[0115] Since the side of this stepped conveyor plate (320) is configured to be in close contact with the inner wall of the housing (310), only one side and the other side are connected.

[0116] That is, as a plurality of stepped conveyor plates (320) are spaced apart from each other upwardly and downwardly to form a connected space, when the blower fan (330) supplies wind from one side to the other, the pure coffee beans and shells (11) and center cuts (12) introduced into the housing (310) are transported from the other side to one side along the stepped conveyor plates (320).

[0117] Depending on the design conditions, a separate vibrator (not shown in the drawing) may be connected to the outside of the stepped conveyor plate (320) or housing (310) consisting of multiple layers.

[0118] These vibrators perform the function of vibrating the stepped conveyor plate (320) so that the pure coffee beans transferred from one side to the other along the stepped conveyor plate (320) can be transferred more easily.

[0119] The blower fan (330) is connected to the other side of the housing (310) and performs the function of supplying wind to the internal space of the housing (310).

[0120] At this time, a separate filter may be provided at the part where the housing (310) and the blower fan (330) are connected.

[0121] Accordingly, the wind supplied into the housing (310) is supplied from the other side of the housing (310) to one side, and the pure coffee beans, shells (11) and center cuts (12) introduced into the housing (310) are caught in the filter and blocked from being introduced into the blower fan (330), and further, the wind supplied through the blower fan (330) can block external foreign substances from being introduced into the housing (310).

[0122] The dust collection unit (340) is connected to one side of the housing (310) and performs the function of collecting the shell (11) and center cut (12) accommodated inside the housing (310).

[0123] That is, by sucking in the husk (11) and center cut (12) that are transferred from one side to the other along the stepped conveyor (320) by the wind supplied from the blower fan (330), the husk (11) and center cut (12) are completely removed from the coffee beans (10), so that only pure coffee beans can be obtained.

[0124] The case (400) is configured to receive pure coffee beans discharged from the separation unit (300), and as shown in FIGS. 2 and 11, is connected to the lower end of one side of the housing (310), thereby receiving pure coffee beans that are transferred from the other side to one side along the step conveyor plate (320) and fall.

[0125] When pure coffee beans and shells (11) and center cuts (12) that have passed through the cyclone (200) are introduced into the separation unit (300) having such a configuration, wind is supplied from the other side of the housing (310) to one side by the blower fan (330) and the dust collector (340), so that the pure coffee beans and shells (11) and center cuts (12) are transferred from the other side to one side along the stepped conveying plate (320) consisting of multiple layers.

[0126] At this time, the relatively light shell (11) and center cut (12) are carried away and collected by the dust collector (340) connected to one side of the housing (310), so that only pure coffee beans remain, and the pure coffee beans are transported to one side along the stepped conveyor plate (320) and fall, thereby being received in the case (400) connected to one side of the housing (310).

[0127] Accordingly, the case (400) can accommodate only pure coffee beans with the shell (11) and center cut (12) completely removed.

[0128] Fig. 12 is a side cross-sectional view showing another embodiment of a stepped conveyor plate in a coffee bean cutter according to the present invention.

[0129] Depending on the design conditions, the stepped conveyor plate (320) may be formed in a shape that slopes downward from one side to the other, as shown in FIG. 12.

[0130] This allows the pure coffee beans, shells (11) and center cuts (12) introduced into the housing (310) to be more flexibly transported from one side to the other by the wind supplied from the blower fan (330).

[0131] That is, since the stepped conveyor plate (320) is formed in an inclined shape, pure coffee beans and shells (11) and center cuts (12) are more easily conveyed along the inclined surface of the stepped conveyor plate (320).

[0132] Meanwhile, when the stepped conveyor plate (320) forming multiple layers is formed in an inclined shape, the housing (310) may also be formed in an inclined shape from the other side to one side in response to the stepped conveyor plate (320).

[0133] Fig. 13 is a side cross-sectional view showing another embodiment of a stepped conveyor plate in a coffee bean cutter according to the present invention.

[0134] Depending on the design conditions, the stepped conveyor plate (320) can be formed to have a wave-shaped cross-section with grooves that become deeper as it goes from one side to the other.

[0135] That is, since the grooves formed by the wave shape are formed in a rough manner in the direction of one side and the other side of the step-type conveyor plate (320), pure coffee beans can be more easily transported from the other side to one side along the grooves.

[0136] Meanwhile, although not shown in the drawing, the stepped conveyor plate (320) having a wave-shaped cross-section may be provided in a form that slopes from one side to the other, depending on the design conditions.

[0137] According to this configuration, the coffee bean cutting machine according to the present invention cuts the center cut (12) and the shell (11) that are vertically cut in the center of the coffee bean (10) during the process of passing through the cutting roller (120, 130), and collects and removes only the cut shell (11) and the center cut (12) in the separation unit (300), thereby obtaining only pure coffee beans from which the shell (11) and the center cut (12) have been removed.

[0138] In addition, the present invention cuts coffee beans (10) by passing between a pair of cutting rollers (120, 130), and the first cutting roller (120), which is one of the pair of cutting rollers (120, 130), is formed in a horizontal shape in which cutting teeth (131) are formed in a longitudinal direction, and the other second cutting roller (130) is formed in a vertical shape in which cutting teeth (131) are formed in a diagonal shape or along a rotating direction, thereby easily cutting the skin (11) and the center cut (12) from the coffee beans (10).

[0139] In addition, the present invention supplies wind to the housing (310) inside the separation unit (300) through the blower fan (330) during the process of passing the cut pure coffee beans and shells (11) and center cuts (12) through the cyclone (200) and then through the separation unit (300), and sucks it in through the dust collecting unit (340), thereby effectively collecting and removing not only the cut shells (11) and center cuts (12) from the coffee beans (10), but also foreign substances such as fine powder, thereby obtaining only pure coffee beans.

[0140] Although the above description has presented and described various embodiments of the present invention, the present invention is not necessarily limited thereto, and it will be apparent to those skilled in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.
