Abstract
Description
Technology Field
[0001] The present invention relates to a mold device for producing koji that can produce koji using a mold device, and a method for producing koji using the same. Background Technology
[0002] Nuruk is a traditional Korean grain made by crushing grains, commonly wheat, into a round or square shape, inoculating and naturally propagating microorganisms, and then drying it; it is a type of fermentation agent used in alcohol production. Various types of nuruk are used depending on the type of raw material (wheat, rice, barley, corn, mung beans, soybeans, red beans, oats, millet, sorghum, etc.) and the shape of the nuruk (round, fist-shaped, egg-shaped, ring-shaped, square).
[0003] Nuruk is shaped using only 10–15% moisture relative to the starch material used. This is because using more moisture than this amount can lead to the formation of molds that cannot be utilized for brewing, rather than the molds and yeasts necessary for brewing, which significantly increases the likelihood of the starch material rotting. Since the ratio of moisture to starch is low, strong pressure must be applied during shaping to ensure that mold forms on the nuruk and the shape does not break upon drying.
[0004] To brew Ihwaju, a spoonable makgeolli, or Baeksuhwandongju, known for its deep flavor, Ihwagok and Baeksuhwandongjugok are required, respectively; these take the form of "jumeok" nuruk, which is shaped into a ball by hand. Since traditional jumeok nuruk is made entirely by hand without molds, it is expensive and labor-intensive.
[0005] In the case of foot-operated disc or square molds, an automated process for vertical compression has been developed due to their simple shape, and they are commercially used for factory production. However, in the case of hand-operated molds, there is no traditional mold, and manpower is required to mold the mold by hand, which reduces production efficiency and requires a large workforce, leading to increased costs.

Specific details for implementing the invention
[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the invention. The present invention may be embodied in various different forms and is not limited to the structures or methods described herein.
[0020] The embodiment of the present invention relates to a mold device for manufacturing fist-shaped koji and a method for manufacturing fist-shaped koji using the same, which allows fist-shaped koji to be easily molded into a spherical shape using a mold device, and enables mass production of uniform fist-shaped koji by applying it to automated equipment, as well as providing fist-shaped koji of excellent quality. Hereinafter, it will be briefly referred to as "mold device and method for manufacturing fist-shaped koji using the same."
[0021] FIG. 1 is a configuration diagram of a mold device for making fist-sized koji according to an embodiment of the present invention, and FIG. 2 is an assembly diagram of a mold device for making fist-sized koji according to an embodiment of the present invention. FIG. 3 is a diagram showing the state in which the molding body of a mold device for making fist-sized koji according to an embodiment of the present invention is rotated to separate it, and FIG. 4 is a detailed diagram of a dual-type rod of a mold device for making fist-sized koji according to an embodiment of the present invention.
[0022] Referring to FIGS. 1 to 4, the mold device of the present invention can easily form a uniform size in the shape of a ball, which is the basic shape of a fist-shaped koji, and can be applied to automated equipment to mass-produce fist-shaped koji, thereby achieving the effect of reducing labor and costs.
[0023] The koji mold device can be installed in an automated facility, and the koji mold device can be used mechanically to automatically produce fist-sized koji for 24 hours, enabling continuous production. Additionally, the koji mold device may include a molding body (100) that forms the shape of fist-sized koji, a dual-type rod (300) that pressurizes the fist-sized koji to form a single mass, and a fixing body (200) that fixes the molding body (100) so that it does not separate.
[0024] The molding body (100) is configured to form the shape of a fist-shaped koji and to facilitate the extraction of the fist-shaped koji. This molding body (100) can be formed in a cylindrical or polygonal box shape and can be configured to be separable and combined into two parts. Additionally, the molding body (100) may be equipped with a spherical koji molding space (101) inside and a material input port (102) penetrating through the upper center of the koji molding space (101).
[0025] In detail, the molding body (100) can be symmetrically formed into a first molding body (110) and a second molding body (120) with respect to a central axis. In this way, the molding body (100) can have a spherical yeast molding space (101) and a material input port (102) open to the top formed inside by combining the two first and second molding bodies (110, 120) into one. That is, the first molding body (110) and the second molding body (120) are each equipped with a hemispherical yeast molding space (101) and a semi-cylindrical groove material input port (102).
[0026] A coupling groove (111) may be formed along the outer surface of the yeast molding space (101) at a certain distance from the first molded body (110) in contact with the second molded body (120). Here, it is preferable that the coupling groove (111) be formed along the outer surface of the first molded body (110) at a certain distance from the hemispherical yeast molding space (101).
[0027] In addition, a connecting projection (121) may be formed on the second molded body (120) at a spaced-apart location along the outer surface of the yeast molding space (101) on the surface in contact with the first molded body (110). The connecting projection (121) is preferably formed at a position corresponding to the connecting groove (111) and has a structure that can be rotated to the position of the connecting groove (111) to be mounted or rotated in the opposite direction to be separated.
[0028] At this time, the first molded body (110) and the second molded body (120) can be rotated at different angles so that the fist-shaped yeast can be easily separated and dropped. That is, by rotating the first molded body (110) and the second molded body (120) so that they are offset from each other, the fist-shaped yeast can be prevented from sticking to the yeast molding space (101).
[0029] As such, the installation structure of the automation equipment can be simplified by the simple separation and connection structure of the first molded body (110) and the second molded body (120), and there is an advantage of minimizing the movement path of the process equipment during manufacturing.
[0030] The fixing body (200) is configured to fix the two separated molded bodies (100) as a single unit. This fixing body (200) is formed in the shape of a band and can wrap around and fix the outer surface of the molded body (100). At this time, the fixing body (200) can be made of an elastic material and formed to be smaller than the outer circumference of the molded body (100) so as to be tightened. Additionally, the fixing body (200) can be formed in the shape of a belt and can be fitted so as to wrap around the outer surface of the molded body (100), with both ends joined together by a buckle and then tightened.
[0031] In contrast, the fixing body (200) may be formed in the shape of a fixed hook and may be installed on the outer surface adjacent to the point where the first molded body (110) and the second molded body (120) come into contact. Additionally, it is preferable that the fixing body (200) be installed in a structure that allows the first molded body (110) and the second molded body (120) to be completely separated from each other. Furthermore, the fixing body (200) is configured so that the first molded body (110) and the second molded body (120) are not separated when the yeast molding space (101) is pressed with a dual-type rod (300) while the molding body (100) is combined.
[0032] The dual-type rod (300) is configured to pressurize the pre-processed powder so that it is formed into the shape of a fist-shaped koji. This dual-type rod (300) is formed in the shape of a long rod and may be equipped with a pressurizing member (310) that is inserted through the material input port (102) to apply pressure. At this time, it is preferable that the dual-type rod (300) be formed smaller than the diameter of the material input port (102).
[0033] Additionally, the dual rod (300) moves up and down vertically within the yeast molding space (101) to pressurize the pretreatment powder introduced into the interior. Furthermore, the dual rod (300) may be equipped with a stopper (320) at the other end of the rod located opposite the pressurizing port (310). The dual rod (300) including this configuration can perform the role of pressurizing the pretreatment powder by the pressurizing port (310) and the role of storing the yeast so that mold forms on the fist-sized yeast while the material input port (102) is sealed by the stopper (320).
[0034] The stopper (320) may consist of a stopper (321) inserted into the material inlet (102) and a cover (322) that is in close contact with and covers the upper surface of the material inlet (102). This stopper (321) may be made of an elastic material and may be formed to a size corresponding to the diameter of the material inlet (102) so as to be used to completely seal the material inlet (102).
[0035] A cover (322) is positioned on one side of the plug (321) and formed to be larger than the diameter of the plug (321) so as to seal the periphery of the material inlet (102). As such, the cover (322) may be made of an elastic material such as the plug (321) and is configured so as not to insert the plug (321) beyond a set depth.
[0036] As shown in FIG. 4, the dual-type rod (300) may be equipped with a stopper (320) that can be detachably mounted. At this time, the dual-type rod (300) is at the other end Mounting groove (301)This is formed as a recess inward and corresponds to the mounting groove (301) on one side of the cover (322) of the plug opening (320). Mounting projection (302) can be formed.
[0037] Here, the mounting projection (302) may be formed to protrude outwardly from the end of the circular bar. In particular, the plug (320) is made of an elastic material and the pressure member (310) is made of a material with high hardness so that the mounting projection (302) of the plug (320) can be fitted into the mounting groove (301) of the rod.
[0038] In this way, the molding device is configured such that, with the molding body (100) integrally combined, the input of pre-treatment powder through the material input port (102) and the application of pressure by the dual rod (300) are repeatedly performed to form a spherical fist-shaped mold. Furthermore, when the fist-shaped mold is completed in the molding space (101), the molding device is configured such that the first molding body (110) and the second molding body (120) of the molding body (100) are rotated in opposite directions to separate them, allowing the fist-shaped mold to fall out of the molding space (101).
[0040] FIG. 5 is a flowchart of a method for manufacturing fist-shaped koji using a koji mold device for manufacturing fist-shaped koji according to an embodiment of the present invention. Referring to FIG. 5, the method for manufacturing fist-shaped koji using a koji mold device of the present invention produces a spherical fist-shaped koji using a koji mold device and illustrates the process of mold forming on the fist-shaped koji.
[0041] A method for manufacturing fist-sized koji using such a koji mold device can proceed in the order of a pretreatment step (S100), a koji mold assembly step (S200), a material input step (S300), a material pressurization step (S400), a repetition step (S500), a material molding step (S600), and a koji separation step (S700).
[0042] In the pretreatment step (S100), the pretreatment powder can be prepared by mixing grain powder and water in a ratio of 8 to 10:1. For example, 100 ml of purified water is added to 1 kg of rice flour in several stages and mixed, and finally, the rice flour containing moisture is sifted again to prepare it in the form of a fine powder containing moisture. That is, the pretreatment step (S100) ensures that 1 / 10 mass of water is evenly added to the starch in the form of fine powder.
[0043] In the mold assembly step (S200), the first molded body (110) and the second molded body (120) of the molding body (100) can be prepared by integrally combining them. At this time, with the first molded body (110) standing in a vertical position, the connecting projection (121) of the second molded body (120) can be rotated and connected by being placed in close contact with the connecting groove (111) in a horizontal position.
[0044] In the material input step (S300), the pretreatment powder can be filled into the yeast molding space (101) inside the molding body (100) up to an arbitrary height. At this time, the pretreatment powder can be input as a starch material containing moisture. In particular, the material input step (S300) is performed repeatedly so that the pretreatment powder can be input into the yeast molding space (101) in multiple portions.
[0045] In the material pressurization step (S400), pressure can be applied to the pretreatment powder by inserting it into the interior of the molding body (100) through the material input port (102) of the molding body (100) toward the pressurization port (310) formed at one end of the dual-type rod (300). Here, the material pressurization step (S400) is performed repeatedly using the dual-type rod (300) to apply pressure so that the pretreatment powder can be well mixed and clumped together.
[0046] In the repetition step (S500), the material input step (S300) and the material pressurization step (S400) are repeated to fill the pretreatment powder up to the top of the molding body (100). For example, after filling the yeast molding space (101) of the molding body (100) with about 1 / 3 of the pretreatment powder, a dual-type rod (300) is inserted into the yeast molding space (101) and pressurized, then after filling the yeast molding space (101) with about 2 / 3 of the pretreatment powder, pressurize with the dual-type rod (300), and then again after filling the yeast molding space (101) with about 3 / 3 of the pretreatment powder, pressurize with the dual-type rod (300).
[0047] In the material forming step (S600), the material is inserted into the upper part of the material input port (102) of the forming body (100) through the stopper (320) formed at the other end of the dual rod (300), and finally, pressure is applied to form it into a ball-shaped fist-shaped koji. At this time, the stopper (321) of the stopper (320) is inserted into the inner side of the material input port (102) to apply pressure, and the fist-shaped koji can be formed while the cover (322) is in close contact with the upper part of the material input port (102).
[0048] In the yeast separation step (S700), the first molded body (110) and the second molded body (120) of the molding body (100) are separated by rotating them apart from each other, and a fist-sized yeast can be obtained from the yeast molding space (101). Here, the coupling groove (111) of the first molded body (110) and the coupling projection (121) of the second molded body (120) can be easily separated by rotating them in opposite directions.
[0049] In the mold inoculation step (S800), the fist-shaped koji can be placed in a sealed koji space set at 35 to 40°C and 80 to 90% humidity to allow mold to inoculate. Here, the molded fist-shaped koji can be stored in a sealed koji box or koji room so that wild yeast or mold can inoculate. At this time, the mold inoculation step (S800) can be performed for 3 days, and the process of mold inoculation can be visually confirmed.
[0050] In the mold formation step (S900), the mold-laden koji can be completely sealed to allow mold to form on the entire surface. At this time, the mold formation step (S900) checks the condition of the koji after 7 days to see if mold has formed on the entire surface.
[0051] In the moisture removal step (S1000), the humidity can be controlled by placing a fist-sized koji with mold formed on its front surface into a sealed koji space set at 28 to 32°C and 75 to 80% humidity. At this time, measures are taken to allow slight ventilation in the sealed koji space so that the humidity can slowly escape.
[0052] In the koji aging step (S1100), mold formed on the entire surface of the koji can be removed and the koji can be stored in a ventilated space to be aged into a finished koji product. At this time, during the koji aging step (S1100), the temperature and humidity and the condition of the koji mold are checked for 7 days, and then the mold on the outer surface of the koji is brushed off with a coarse brush or cut off with a knife, and the koji can be stored in a place where sunlight does not reach and there is good ventilation to be aged for 3 months to complete the finished koji product.
[0053] Those skilled in the art to which the present invention pertains will understand that the invention may be implemented in modified forms without departing from the essential nature of the invention. Therefore, the disclosed embodiments should be considered in an illustrative rather than a limiting sense. The scope of the invention is defined by the claims, not by the foregoing description, and all variations within the scope of the claims should be interpreted as being included in the invention.
