[0086] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without carrying out creative work are within the scope of protection of the present disclosure.

[0087] The technologies, methods and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered as part of the specification when appropriate.

[0088] In the description of the present disclosure, it should be understood that the use of the words "first", "second" and the like to qualify elements is only for the convenience of distinguishing the corresponding elements, and the above words have no special meaning unless otherwise stated, and therefore cannot be understood as a limitation on the scope of protection of the present disclosure.

[0089] In the description of the present disclosure, it should be understood that the orientation words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicate the orientation or positional relationship generally based on the orientation or positional relationship when the koji making machine is normally placed, wherein the direction opposite to the gravity is the down direction, and the direction same as the gravity is the down direction; the orientation words "inner, outer" refer to the inner and outer relative to the contour of the components themselves.

[0090] In addition, the technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as there is no conflict.

[0091] Figures 1-42 The structure of the koji making machine of the present disclosure is exemplarily shown. In order to clearly show the structures, some structures are simplified or omitted in some drawings.

[0092] Referring to Figures 1-42 , the koji making machine 10 comprises a disc 1, a discharging mechanism 2, a feeding mechanism 3, a stirring mechanism 4 and a frame 91.

[0093] The disc 1 is used to hold the material 20 and provide a fermentation site for the material 20. The discharging mechanism 2 is used to transport the brewed or fermented material 20 from the disc 1 to a designated position in the downstream process. The feeding mechanism 3 is used to send the material 20 that needs to be fermented into the disc 1. The stirring mechanism 4 is used to stir the material 20 on the disc 1 during fermentation to make the fermentation more uniform and sufficient. The frame 91 is used to provide support for the disc 1.

[0094] The disc 1 is arranged on the frame 91 and supported by the frame 91. The discharging mechanism 2, the feeding mechanism 3 and the stirring mechanism 4 are arranged above the disc 1 and are arranged relatively rotatably with the disc 1, so as to realize the discharging, feeding and stirring of the disc 1 in the entire circumferential direction by the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the stirring mechanism 4 and the disc 1. In order to realize the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the stirring mechanism 4 and the disc 1, the disc 1 can be rotated while the discharging mechanism 2, the feeding mechanism 3 and the stirring mechanism 4 are not rotated, or the discharging mechanism 2, the feeding mechanism 3 and the stirring mechanism 4 can be rotated while the disc 1 is not rotated. Here, the rotation of the disc 1, the discharging mechanism 2, the feeding mechanism 3 and the stirring mechanism 4 refers to the rotation around the longitudinal geometric center line of the disc 1. The longitudinal geometric center line of the disc 1 is also referred to as the longitudinal rotation axis in the following.

[0095] Referring to Figures 2-3 In the embodiments of the present disclosure, the disc 1 comprises a disc body 11, an inner ring 12 and an outer ring 13. The inner ring 12 and the outer ring 13 are arranged at the inner and outer circles of the disc body 11 respectively and are both extended upward by the disc body 11 to form the inner wall and the outer wall of the disc 1, so that the disc 1 as a whole is in the shape of a ring groove.

[0096] Compared with the disc 1 without the annular groove, the disc 1 with the annular groove has a wider application range, because the disc 1 with the annular groove can be used not only for the fermentation of solid materials, but also for the fermentation of liquid or mixed solid-liquid materials, and provides a basis for the fermentation of materials containing liquid. When the disc 1 has the annular groove, the outer ring 13 and the inner ring 12 can block the material 20 from falling off from the outer edge or the inner edge of the disc body 11, and in particular, when the material 20 contains liquid, the outer ring 13 and the inner ring 12 can prevent the material 20 from flowing to the outside of the disc body 11 from the inner side and the outer side in the radial direction, so that the fermentation and brewing of the material 20, especially the material 20 containing liquid, can be more conveniently achieved.

[0097] However, the disc 1 with the annular groove has a problem of difficult discharging. The disc 1 without the annular groove can be conveniently discharged from the radial side of the disc 1, for example, for the disc 1 without the outer ring 13, a discharging mode (which can be referred to as an outer ring discharging mode) of discharging the material from the outer side in the radial direction is usually adopted, that is, the discharging mechanism 2 transports the material to the outer side in the radial direction of the disc 1 after the fermentation of the material is completed, and discharges the material from the outer side in the radial direction of the disc 1. Since the outer edge of the disc body 11 is not provided with the outer ring 13, the material 20 can directly fall off from the outer edge of the disc body 11 under the action of the discharging mechanism 2, so that the outer ring discharging is achieved. However, for the disc 1 with the annular groove, since the outer edge and the inner edge of the disc body 11 are respectively provided with the outer ring 13 and the inner ring 12, the outer ring 13 and the inner ring 12 will block the discharge of the material 20, so that it is difficult to directly use the conventional discharging mechanism 2 to discharge the material from the radial side of the disc body 11.

[0098] The conventional discharging mechanism 2 usually directly uses a screw conveyor or a scraper conveyor to discharge. When discharging is needed, the screw conveyor or the scraper conveyor is in contact with the disc body 11, and transports the material 20 by rotating around the axis thereof. Such a conventional discharging mechanism 2 can smoothly discharge the material for the disc 1 without the annular groove, but for the disc 1 with the annular groove, since the material transported by the screw conveyor or the scraper conveyor is blocked by the inner ring 12 and the outer ring 13 during the discharging process, the material cannot be smoothly discharged.

[0099] It can be seen that the discharging problem is an important problem restricting the development of the disc-type koji-making machine with the annular groove, and needs to be solved urgently.

[0100] In view of the above situation, it is proposed to Figures 2-6In the embodiments of the present disclosure, the discharging mechanism 2 is configured to transport the material 20 to the radial side of the disc 1, and make the material 20 transported to the radial side of the disc 1 rise above the inner ring 12 or the outer ring 13 and fall from the inner side of the inner ring 12 or the outer side of the outer ring 13. It can be understood that the inner side and the outer side are relative to the longitudinal center line of the disc 1, the side close to the longitudinal center line of the disc 1 is the inner side, and the side far away from the longitudinal center line of the disc 1 is the outer side. Therefore, the inner side of the inner ring 12 refers to the side of the inner ring 12 close to the longitudinal center line of the disc 1, and the outer side of the outer ring 13 refers to the side of the outer ring 13 far away from the longitudinal center line of the disc 1.

[0101] Based on the above settings, the discharging mechanism 2 can transport the material 20 by first transporting radially and then transporting upwardly. Since the material 20 can rise above the inner ring 12 or the outer ring 13 and thus is no longer blocked by the inner ring 12 or the outer ring 13, the material 20 can fall smoothly to the outside of the disc 1, thereby realizing the discharging process.

[0102] For example, in some embodiments, the discharging mechanism 2 can first transport the material 20 to the radial outer side of the disc 1, and then make the material 20 transported to the radial outer side rise above the outer ring 13 and fall from the outer side of the outer ring 13, thereby realizing the outer ring discharging. This outer ring discharging mode is particularly suitable for the case where the disc 1 rotates and the discharging mechanism 2 does not rotate, because when the discharging mechanism 2 does not rotate, the material 20 can be discharged from a certain circumferential position without being discharged along the entire circumference. In this case, it is convenient to collect the material 20 fallen during the outer ring discharging process. For example, when a receiving device such as a receiving tray is arranged below the falling point to receive the material, the receiving device only needs to have a small size and does not need to surround the entire outer periphery with a large diameter, so the cost is low and the occupied area is small.

[0103] For another example, in some other embodiments, the discharging mechanism 2 can first transport the material 20 to the radial inner side of the disc 1, and then make the material 20 transported to the radial inner side rise above the inner ring 12 and fall from the inner side of the inner ring 12, thereby realizing the center discharging. At this time, the center of the disc body 11 can be provided with a discharging port 14, so that the material 20 falling from the inner side of the inner ring 12 can be discharged through the discharging port 14. This center discharging mode has a wider range of application and can be conveniently used in the case where the disc 1 rotates or does not rotate. Because the inner diameter of the disc 1 is smaller than the outer diameter of the disc 1, the outlet of the discharging port 14 located at the center of the disc body 11 can be smaller, so whether the disc 1 rotates relative to the discharging mechanism 2 or the discharging mechanism 2 rotates relative to the disc 1, the material 20 falling from the discharging port 14 can be conveniently received. For example, when a receiving device such as a receiving tray is arranged below the discharging port 14 to receive the material, the receiving device only needs to have a small diameter, so the cost is low and the occupied area is small.

[0104] It can be seen that the discharge mechanism 2 can be used to conveniently discharge the material 20 without being blocked by the inner ring 12 or the outer ring 13 by first being radially conveyed and then being upwardly conveyed, thereby ingeniously solving the problem of discharging the ring groove-shaped disc, which is conducive to the popularization and application of the ring groove-shaped disc and facilitates the fermentation and brewing of the liquid-containing material.

[0105] Since the discharge mechanism 2 is provided, the automatic discharge of the ring groove-shaped disc can be realized without changing the structure of the disc 1 itself, so the structure is relatively simple, and since the discharge door does not need to be provided on the disc 1, the disc 1 can maintain better integrity and better sealing performance, and can more reliably prevent material leakage, which is particularly important for the fermentation and brewing of the liquid-containing material.

[0106] As an embodiment of the discharge mechanism 2, refer to Figures 2-6 In some embodiments, the discharge mechanism 2 includes a conveyor 21 and a material guiding device 2b. The conveyor 21 is arranged along the radial direction of the disc 1 to convey the material 20 along the radial direction of the disc 1. The material guiding device 2b is arranged at the conveyor 21 and guides the material 20 conveyed by the conveyor 21 to rise above the inner ring 12 or the outer ring 13 and reach the inner side of the inner ring 12 or the outer side of the outer ring 13.

[0107] Since the conveyor 21 is arranged along the radial direction of the disc 1 and conveys the material 20 along the radial direction of the disc 1, the conveyor 21 can convey the material 20 to the radial side of the disc 1, for example, in the case of central discharge, the material 20 can be conveyed to the radial inner side of the disc 1 where the inner ring 12 is located, or in the case of outer ring discharge, the material 20 can be conveyed to the radial outer side of the disc 1 where the outer ring 13 is located.

[0108] And since the material guiding device 2b can guide the material 20 conveyed by the conveyor 21 to rise above the inner ring 12 or the outer ring 13 and reach the inner side of the inner ring 12 or the outer side of the outer ring 13, the material 20 conveyed by the conveyor 21 to the radial side of the disc 1 can be guided by the material guiding device 2b to rise above the inner ring 12 or the outer ring 13 and fall from the inner side of the inner ring 12 or the outer side of the outer ring 13, for example, in the case of central discharge, the material 20 conveyed by the conveyor 21 to the radial inner side of the disc 1 can be guided by the material guiding device 2b to above the inner ring 12 and fall from the discharge port 14 located on the radial inner side of the inner ring 12, or in the case of outer ring discharge, the material 20 conveyed by the conveyor 21 to the radial outer side of the disc 1 can be guided by the material guiding device 2b to above the outer ring 13 and fall from the outer side of the outer ring 13.

[0109] It can be seen that the discharge mechanism 2 can realize the mode of first being radially conveyed and then being upwardly conveyed by the cooperation of the conveyor 21 and the material guiding device 2b, thereby smoothly realizing the discharge of the ring groove-shaped disc.

[0110] In order to make the material guiding device 2b have the required material guiding effect, see Figures 2-6 In some embodiments, the material guiding device 2b comprises a material blocking plate 26, a material guiding sleeve 27 and a material guiding pipe 28, the material blocking plate 26 is arranged at one side of the circumference of the conveyor 21 and at one end of the conveyor 21, the material guiding sleeve 27 is circumferentially closed and sleeved at the other end of the conveyor 21, the material guiding sleeve 27 and the material blocking plate 26 are in abutment in the radial direction of the disc 1, and the material guiding pipe 28 is in communication with the inside of the material guiding sleeve 27 and the inside of the inner ring 12 or the outside of the outer ring 13.

[0111] In the above, the material guiding sleeve 27 is circumferentially closed, that is, the material guiding sleeve 27 has no opening in the entire circumference except the material guiding pipe 28, and the material 20 cannot flow out of the material guiding sleeve 27 to the outside of the material guiding sleeve 27 from the positions other than the material guiding pipe 28.

[0112] The material guiding sleeve 27 and the material blocking plate 26 are in abutment in the radial direction of the disc 1, that is, in the radial direction of the disc 1 (also the axial direction of the conveyor 21), the end of the material blocking plate 26 facing the material guiding sleeve 27 is in contact with the end of the material guiding sleeve 27 facing the material blocking plate 26, or there is only a small gap between the two. When there is only a small gap between the end of the material blocking plate 26 facing the material guiding sleeve 27 and the end of the material guiding sleeve 27 facing the material blocking plate 26, the gap between the two is preferably such that the material 20 does not leak out of the corresponding gap.

[0113] Since the material blocking plate 26 is located at one side of the circumference of the conveyor 21, the material blocking plate 26 can block the material 20 to prevent the material 20 from leaking out from the side where the material blocking plate 26 is located during the relative rotation of the conveyor 21 and the disc 1. Thus, during the relative rotation of the conveyor 21 and the disc 1, the material 20 can be blocked at the conveyor 21 and conveyed by the conveyor 21 to the radial outside or inside.

[0114] Furthermore, since the material guiding sleeve 27 and the material blocking plate 26 are arranged at opposite ends of the conveyor 21 and in abutment with each other, and the material guiding sleeve 27 is circumferentially closed and only communicates with the inside of the inner ring 12 or the outside of the outer ring 13 through the material guiding pipe 28 at the material guiding pipe 28, the material 20 conveyed by the conveyor 21 to the radial inside or radial outside will enter the material guiding sleeve 27 and be squeezed in the material guiding sleeve 27, enter the material guiding pipe 28, follow the material guiding pipe 28 to the upper side of the inner ring 12 or the upper side of the outer ring 13, and fall from the inside of the inner ring 12 or the outside of the outer ring 13, realizing center discharging or outer ring discharging.

[0115] It can be seen that the material guide sleeve 27 and the material guide pipe 28 can cooperate with the conveyor 21 to block the material 20 in the circumferential direction and guide it upward, so that the material 20 transported to the radial outer side can only move upward of the outer ring 13 under the action of the conveyor 21, and the material 20 transported to the radial inner side can only move upward of the inner ring 12, and finally realize the outer ring discharging or the center discharging.

[0116] In the case of needing outer ring discharging, the material blocking plate 26 can be arranged at one end of the conveyor 21 close to the radial inner side of the disc 1 (i.e. one end of the conveyor 21 close to the inner ring 12), and the closed material guide sleeve 27 is sleeved at one end of the conveyor 21 close to the radial outer side of the disc 1 (i.e. one end of the conveyor 21 close to the outer ring 13), and the material guide pipe 28 extends upward from the material guide sleeve 27 to the upper side of the outer ring 13 and further extends outward of the outer ring 13, so that the inside of the material guide sleeve 27 and the outside of the outer ring 13 are connected through the material guide pipe 28. Thus, when discharging is needed, the conveyor 21 only needs to rotate around its own axis in the first direction to transport the material 20 to the radial outer side, so that the material 20 can be sent to the inside of the material guide sleeve 27. Since the conveyor 21 continuously transports the material 20 to the inside of the material guide sleeve 27, the space inside the material guide sleeve 27 is limited, so the material 20 inside the material guide sleeve 27 is continuously extruded and finally extruded into the material guide pipe 28, reaches the upper side and the outside of the outer ring 13 along the material guide pipe 28, and falls from the outside of the outer ring 13, completing the outer ring discharging process.

[0117] In the case of needing center discharging, referring to Figures 2-3 , the material blocking plate 26 can be arranged at one end of the conveyor 21 close to the radial outer side of the disc 1 (i.e. one end of the conveyor 21 close to the outer ring 13), and the closed material guide sleeve 27 is sleeved at one end of the conveyor 21 close to the radial inner side of the disc 1 (i.e. one end of the conveyor 21 close to the inner ring 12), and the material guide pipe 28 extends upward from the material guide sleeve 27 to the upper side of the inner ring 12 and further extends inward of the inner ring 12, so that the inside of the material guide sleeve 27 and the inside of the inner ring 12 are connected through the material guide pipe 28. Thus, when discharging is needed, the conveyor 21 only needs to rotate around its own axis in the second direction to transport the material 20 to the radial inner side, so that the material 20 can be sent to the inside of the material guide sleeve 27. With the continuous transportation process, the material 20 inside the material guide sleeve 27 is extruded into the material guide pipe 28, so that the material 20 reaches the upper side and the inside of the inner ring 12 via the material guide pipe 28, and falls from the discharging port 14 located on the inside of the inner ring 12, completing the center discharging process.

[0118] It can be seen that in the above arrangement, the material guiding device 2b can guide and lift the material 20 conveyed by the conveyor 21 to the upper side of the inner ring 12 or the outer ring 13 based on the cooperation of the material blocking plate 26, the material guiding sleeve 27 and the material guiding pipe 28, so that the material guiding device 2b can cooperate with the conveyor 21 to smoothly discharge the material.

[0119] As a further improvement of the material guiding device 2b in the foregoing arrangement, referring to Figure 4 In some embodiments, the material guiding device 2b comprises a scraper 2a connected to the lower end of the material blocking plate 26 for scraping the material 20 on the disc 1. Based on this arrangement, the scraper 2a can block the material together with the material blocking plate 26, and can continuously scrape the material 20 on the disc 1 during the relative rotation of the discharging mechanism 2 and the disc 1 to provide the conveyor 21, so as to reduce the residue of the material 20 on the disc 1 and achieve a more clean and thorough discharging process.

[0120] In addition, referring to Figures 5-6 In some embodiments, the material guiding device 2b comprises a material guiding plate 29 extending from the material guiding sleeve 27 to a side away from the material blocking plate 26 and inclined to gradually move away from the material guiding sleeve 27 along the direction from the material blocking plate 26 to the material guiding sleeve 27.

[0121] Based on the arrangement of the material guiding plate 29, the material 20 in the same radial range as the material guiding sleeve 27 can reach the conveyor 21 along the material guiding plate 29 during the relative rotation of the discharging mechanism 2 and the disc 1 and be conveyed by the conveyor 21. Since this can prevent the part of the conveyor 21 inside the material guiding sleeve 21 from contacting the material 20 in the corresponding radial range, thereby preventing the material 20 in the corresponding radial range from being discharged, it is beneficial to reduce the residue of the material 20 on the disc 1 and improve the cleanliness of the discharging process.

[0122] For example, in the case of central discharging, referring to Figure 6 The material guiding plate 29 can be inclinedly extended from the material guiding sleeve 27 to the inner ring 12, and the inclination direction is gradually away from the material guiding sleeve 27 along the direction from the radial outside to the radial inside. In this way, a circle of material 20 in the radial inside range corresponding to the material guiding sleeve 27 can reach the conveyor 21 along the material guiding plate 29 during the relative rotation of the discharging mechanism 2 and the disc 1 and be conveyed by the conveyor 21 to the inside of the material guiding sleeve 21 for discharging. Since this can prevent the part of the material 20 from being missed, it can achieve a more clean central discharging process.

[0123] For example, in the case of discharging the material 20 from the outer ring, the guide plate 29 can extend obliquely from the guide sleeve 27 towards the outer ring 13, and the oblique direction is gradually away from the guide sleeve 27 from the radial inner side to the radial outer side, so that during the relative rotation of the discharging mechanism 2 and the disc 1, the material 20 in the range of the radial outer side corresponding to the guide sleeve 27 can reach the conveyor 21 along the guide plate 29, and then be conveyed to the guide sleeve 27 by the conveyor 21 for discharging. Since this can prevent the part of the material 20 from being missed, a cleaner discharging process from the outer ring can be achieved.

[0124] As can be seen, the guide plate 29 can guide the material 20 in the same radial range as the guide sleeve 27 to flow to the conveyor 21, so that the material 20 in the same radial range as the guide sleeve 27 can reach the conveyor 21 along the guide plate 27 and be conveyed by the conveyor 21, achieving a cleaner and more thorough discharging process.

[0125] In addition, referring to Figure 2 and Figure 3 In some embodiments, the koji maker 10 comprises a spraying device 25 for spraying liquid to the material 20 on the disc 1 and / or the discharging mechanism 2.

[0126] Spraying liquid to the material 20 on the disc 1 by the spraying device 25 can facilitate the fermentation and brewing requirements and the conveying requirements of the material, for example, some materials 20 need to be added with water or other liquids during fermentation and brewing to ferment well, so spraying liquid to the material 20 on the disc 1 by the spraying device 25 can better meet the process requirements of the fermentation and brewing of these materials 20; for example, some materials 20 are difficult to convey due to their own characteristics, so spraying liquid to the material 20 on the disc 1 by the spraying device 25 can better meet the conveying requirements of these materials 20, and the conveying of these materials 20 can be facilitated by diluting these materials 20, for example, the discharging of these materials 20 can be facilitated.

[0127] Spraying liquid to the discharging mechanism 2 by the spraying device 25 can achieve cleaning of the discharging mechanism 2, which is conducive to keeping the discharging mechanism 2 clean.

[0128] As can be seen, based on the spraying device 25, the fermentation and brewing process, the material conveying process and the equipment cleaning process can be better met by spraying liquid to the material 20 and / or the discharging mechanism 2.

[0129] The spraying device 25 can be arranged on the discharging mechanism 2, so that the spraying device 25 can conveniently spray liquid to the discharging mechanism 2 when the discharging mechanism 2 needs to be cleaned, and can also conveniently spray liquid to the material 20 during the fermentation and brewing process or the discharging process.

[0130] In addition, in the related art, in the fermentation brewing process, only direct ventilation is usually used to adjust the temperature of the material 20, the temperature adjustment mode is relatively single, and the temperature adjustment effect needs to be improved, which affects the overall fermentation brewing effect. In view of this situation, the temperature adjustment mode of the material 20 is improved in the embodiments of the present disclosure, so that the temperature adjustment mode is no longer limited to direct ventilation heat exchange, but also can use indirect heat exchange to adjust the material temperature.

[0131] As one of the indirect heat exchange temperature adjustment modes, see Figure 15 In some embodiments, the koji making machine 10 includes a temperature adjustment device 5, and the temperature adjustment device 5 includes a heat exchanger 51, which is rotatably arranged relative to the disc 1 and extends into the material 20 on the disc 1.

[0132] The heat exchanger 51 is a heat exchanger with a heat exchange medium (such as water or other liquid) inside, so that when it extends into the material 20, heat exchange between the material 20 and the heat exchange medium can be achieved, and the temperature of the material 20 can be adjusted to meet the temperature requirements of the fermentation brewing process.

[0133] In addition, since the heat exchanger 51 is rotatably arranged relative to the disc 1, the heat exchanger 51 can adjust the temperature of the material 20 at different circumferential positions on the disc 1 to meet the temperature adjustment requirements of the material 20 on the entire disc 1. At the same time, the relative rotation between the heat exchanger 51 and the disc 1 also causes the relative movement between the heat exchanger 51 and the material 20, so that the heat exchanger 51 can have a certain stirring effect on the material 20, so that the heat exchanger 51 can have both temperature adjustment function and material stirring function.

[0134] It can be seen that based on the arranged heat exchanger 51, the temperature adjustment device 5 can realize indirect heat exchange, enrich the temperature adjustment mode of the koji making machine 10, and make the koji making machine 10 not limited to direct ventilation heat exchange as the only temperature adjustment mode. In addition, based on the arranged heat exchanger 51, the temperature adjustment device 5 can not only control the temperature of the material, but also stir the material, which is one machine with two functions and rich in functions.

[0135] The temperature adjustment device 5 can be lifted relative to the disc 1 to control contact with the material 20 when needed.

[0136] The temperature adjusting device 5 can realize the material stirring function only by the relative movement with the disc 1. In this case, the stirring strength of the temperature adjusting device 5 is smaller than that of the conventional material stirring mechanism 4 which rotates around the disc 1 and rotates around its own axis. Therefore, the temperature adjusting device 5 is especially suitable for the material 20 which is not suitable for being stirred intensively. In the fermentation and brewing process of some materials 20, the fermentation and brewing effect can be affected if the material 20 is stirred intensively. In this case, the temperature adjusting device 5 can be used to realize the material stirring function and meet the requirement of the material 20 for the stirring process with lower strength.

[0137] In the case that the koji making machine 10 simultaneously comprises the temperature adjusting device 5 and the material stirring mechanism 4, the temperature adjusting device 5 can meet more various material stirring requirements together with the material stirring mechanism 4 and enhance the working flexibility of the koji making machine 10. For example, in the case that the material 20 requires intensive stirring, the material stirring mechanism 4 can be started to stir, or the temperature adjusting device 5 and the material stirring mechanism 4 can be used together to stir. In the case that the material 20 requires non-intensive stirring, only the temperature adjusting device 5 can be used to stir, and the material stirring mechanism 4 is not started.

[0138] As another indirect heat exchange temperature adjusting mode, see Figures 30-35 and Figures 41-42 In some embodiments, the disc 1 is internally provided with a chamber 15, and the koji making machine 10 comprises a first heat exchange system 81 which is in communication with the chamber 15 and introduces heat exchange fluid into the chamber 15, so as to adjust the temperature of the material 20 by using the heat exchange between the heat exchange fluid and the material 20 on the disc 1.

[0139] In the above setting mode, the disc 1 is no longer a solid disc, but has a hollow sandwich layer, and the heat exchange fluid can be introduced into the sandwich layer by the first heat exchange system 81 to realize the temperature control of the material 20 by using the heat exchange between the heat exchange fluid and the material 20. The first heat exchange system 81 can be referred to as a sandwich heat exchange system. The heat exchange fluid introduced into the sandwich layer can be a liquid such as water, so as to better exchange heat with the material 20 and achieve better temperature control effect.

[0140] It can be seen that, based on the first heat exchange system 81, the indirect heat exchange temperature adjusting mode based on the heat exchange between the heat exchange medium and the material 20 can also be realized, the temperature adjusting modes of the koji making machine 10 are enriched, and the koji making machine 10 is no longer limited to the direct ventilation temperature adjusting mode.

[0141] In the above setting mode, the chamber 15 can be located inside at least one of the disc body 11, the outer ring 13 and the inner ring 12 of the disc 1, so that the disc 1 as a whole or in part has a sandwich structure. The parts of the chamber 15 located inside the disc body 11, the outer ring 13 and the inner ring 12 can be respectively referred to as a first chamber 151, a second chamber 152 and a third chamber (not shown in the figure) for easy distinction.

[0142] For example, seeFigures 30-31 In some embodiments, the chamber 15 comprises a first cavity 151 arranged inside the disc body 11, in which case the disc body 11 is a sandwich structure. Since the material 20 is mainly stacked on the disc body 11, the disc body 11 is arranged as a sandwich structure, and the heat exchange fluid is introduced into the sandwich of the disc body 11, which can meet the heat exchange needs of most of the material 20, and achieve a better temperature adjustment effect. Referring to Figure 32 and Figure 42 The first cavity 151 inside the disc body 11 can be divided into at least two heat exchange cavities 153, and the bottom wall of each heat exchange cavity 153 is provided with an inlet 157 and an outlet 158 for the heat exchange fluid to flow into and out of the first cavity 151, respectively. By arranging different heat exchange cavities 153 inside the disc body 11, the disc body 11 can be divided into different regions for heat exchange. Since each region can be independently heat exchanged, the failure of a certain region does not affect the heat exchange of other regions, which is highly reliable and easy to maintain. This disc body 11 heat exchange method is suitable for both the case where the disc 1 rotates (see Figures 32-35 ) and the case where the disc 1 does not rotate (see Figure 42 ). The heat exchange cavities 153 can be arranged along the circumference of the disc 1 in sequence and cover the entire circumference of the disc body 11, so as to achieve heat exchange of the material 20 on the entire circumference of the disc body 11.

[0143] For another example, referring back to Figures 30-31 In some embodiments, the chamber 15 comprises a second cavity 152 arranged inside the outer ring 13, in which case the outer ring 13 is a sandwich structure. The heat exchange fluid in the sandwich of the outer ring 13 can conveniently exchange heat with the material 20 at different heights (or thicknesses), achieving a better temperature adjustment effect.

[0144] For another example, continuing to refer to Figures 30-31 In some embodiments, the chamber 15 comprises both the first cavity 151 and the second cavity 152, in which case the disc body 11 and the outer ring 13 are both sandwich structures. In this case, not only can the heat exchange fluid in the disc body 11 exchange heat with the material 20, but also the heat exchange fluid in the outer ring 13 can exchange heat with the material 20, so that the bottom and side of the material 20 can exchange heat with the heat exchange fluid, which is beneficial to prevent temperature unevenness of the material 20 in the circumferential or height direction, and achieve a more uniform temperature adjustment effect.

[0145] In the case that the chamber 15 comprises both the first chamber 151 and the second chamber 152, the second chamber 152 can be in communication with the first chamber 151, and the heat exchange fluid provided by the first heat exchange system 81 can flow from the first chamber 151 to the second chamber 152, and flow out of the second chamber 152 to the outside of the disc 1. In this way, the heat exchange fluid can be fully exchanged with the material 20 in the disc body 11, and then flow to the outer ring 13 to exchange heat with the material 20. This heat exchange method of first the disc body 11 and then the outer ring 13 is more in line with the characteristics of the material 20, i.e. a large flat area and a small thickness, and the heat exchange demand of the disc body 11 is greater, which is conducive to achieving better heat exchange effect. In addition, this heat exchange method of first the disc body 11 and then the outer ring 13 is also more convenient for the arrangement of the first heat exchange system 81. At this time, the first heat exchange system 81 can be arranged below the disc body 11. Since the space below the disc body 11 is large, the arrangement is convenient, especially for the arrangement of the first heat exchange system 81 when the disc 1 rotates.

[0146] When the disc 1 rotates, how to arrange the first heat exchange system 81 to avoid the entanglement of the pipeline during the rotation of the disc 1 is a difficult problem.

[0147] In order to solve the entanglement problem of the pipeline of the first heat exchange system 81 during the rotation of the disc 1, see Figures 30-31 In some embodiments, when the disc 1 is rotatably arranged, the chamber 15 comprises a first chamber 151 arranged inside the disc body 11, and the first heat exchange system 81 comprises a first shell 811 and a second shell 812. The first shell 811 is arranged on the disc body 11 and rotates with the disc body 11. The second shell 812 is connected below the first shell 811 and is rotatably arranged relative to the first shell 811. The first shell 811 is provided with an entering ring groove 813 and an discharging ring groove 814 which are separated from each other. The second shell 812 is provided with an entering port 818 and a discharging port 819 which are separated from each other. The entering port 818 is in communication with the first chamber 151 through the entering ring groove 813. The discharging port 819 is in communication with the first chamber 151 through the discharging ring groove 814. The entering port 818 is connected with an entering pipe 81a which is in communication with a heat exchange fluid supply source. The discharging port 819 is connected with a discharging pipe 81b for discharging the heat exchange fluid.

[0148] Based on the above setting, the heat exchange fluid enters the first cavity 151 through the inlet 818 and the inlet ring groove 813, and flows out to the outside from the outlet ring groove 814 and the outlet 819 after flowing through the disc 1. During the whole process, since the first shell 811 provided with the inlet ring groove 813 and the outlet ring groove 814 rotates with the disc body 11, and the second shell 812 connected with the inlet pipe 81a and the outlet pipe 81b does not rotate with the disc body 11, the flow of the heat exchange fluid is not affected by the rotation of the disc 1. No matter at which angle the disc 1 rotates, the inlet pipe 81a and the outlet pipe 81b can be in the original position and do not rotate with it, and at the same time, the heat exchange fluid can enter and exit the first cavity 151 through the inlet ring groove 813 and the outlet ring groove 814, realizing the interlayer heat exchange. It can be seen that the above setting can meet the supply demand of the heat exchange fluid of the whole rotating disc 1 while effectively avoiding the winding of the inlet pipe 81a and the outlet pipe 81b.

[0149] Since the space at the lower part of the disc body 11 is large and basically has no obstruction, the first shell 811, the second shell 812, the inlet pipe 81a and the outlet pipe 81b can be conveniently arranged, thereby conveniently realizing the arrangement and installation of the first heat exchange system 81.

[0150] Among them, referring to Figure 31 In some embodiments, the inlet ring groove 813 is located radially inside the outlet ring groove 814, which is more compact and reasonable in layout, and facilitates the heat exchange fluid to flow to the radially inner side after entering the first cavity 151, and then flow to the radially outer side, orderly realizing the temperature regulation of the material 20 at each part of the disc body 11.

[0151] In order to guide the orderly flow of the heat exchange fluid in the disc body 11, referring to Figures 31-35 In some embodiments, the first cavity 151 is provided with a first partition plate 154 and a second partition plate 155. The first partition plate 154 extends along the radial direction of the disc 1 and is spaced apart from the inner ring 12. The second partition plate 155 is located on one side of the first partition plate 154 along the circumferential direction of the disc 1 and separates the space of the first cavity 151 on the side of the first partition plate 154 along the circumferential direction of the disc 1. The bottom wall of the first cavity 151 is provided with an inlet 157 and an outlet 158. The inlet 157 and the outlet 158 are respectively communicated with the inlet ring groove 813 and the outlet ring groove 814. The inlet 157 and the inlet ring groove 813 and the outlet 158 and the outlet ring groove 814 are located on opposite sides of the second partition plate 155 along the radial direction of the disc 1.

[0152] Based on the above setting, the heat exchange fluid entering the first cavity 151 can orderly flow through different positions of the disc body 11 along the radial direction, and finally flow through the whole disc body 11, and fully exchange heat with the material 20 on the disc body 11.

[0153] Here, the case where the inlet annular groove 813 is located radially inward of the outlet annular groove 814 is taken as an example to describe the flow process of the heat exchange fluid based on the above arrangement.

[0154] Referring to Figures 30-35 When the inlet annular groove 813 is located radially inward of the outlet annular groove 814, the heat exchange fluid flowing into the inlet annular groove 813 can enter the first cavity 151 through the inlet 157. The heat exchange fluid entering the first cavity 151 can only flow in the space of the first cavity 151 located on the side of the first baffle 154 along the circumferential direction of the disc 1 (the space on the side where the inlet 157 is located, which is indicated as the first space 15a in Figure 33 Fig. 2) due to the blocking of the first baffle 154. The heat exchange fluid cannot flow radially outward of the disc 1 but only radially inward of the disc 1 due to the blocking of the second baffle 155. When the heat exchange fluid flows to the position close to the inner ring 12, it flows into the space of the first cavity 151 located on the other side of the first baffle 154 along the circumferential direction of the disc 1 (the space on the other side where the inlet 157 is not located, which is indicated as the second space 15b in Figure 33 Fig. 2) through the gap between the inner ring 12 and the first baffle 154, and then turns back to flow radially outward of the disc 1 and finally flows to the outlet 158 and flows out of the disc body 11 through the outlet 158. The heat exchange fluid flowing out of the disc body 11 flows through the outlet annular groove 814, the outlet 819 and the outlet pipe 81b in sequence as shown in Figure 31 Fig. 2, and flows back to the heat exchange fluid supply source to realize the circulation flow of the heat exchange fluid.

[0155] When the second cavity 152 is arranged in the outer ring 13, the heat exchange fluid flowing radially inward of the disc body 11 to radially outward of the disc body 11 flows into the second cavity 152 through the inlet I of the second cavity 152 as shown in Figures 32-33 Fig. 2 when flowing to the position close to the outer ring 13, and then flows back to the first cavity 151 through the outlet O of the second cavity 152 after flowing through the second cavity 152, and then flows radially inward until flowing to the outlet 158 and flowing out of the disc body 11 through the outlet 158. At this time, the first baffle 154 and the outer ring 13 are in contact with each other without a gap therebetween to prevent the fluid flowing to the outer ring 13 from flowing to the second cavity 152 but directly flowing to the outlet 158.

[0156] When the second cavity 152 is not arranged in the outer ring 13, the heat exchange fluid flowing radially inward of the disc body 11 to radially outward of the disc body 11 flows to the position close to the outer ring 13 as shown in Figures 34-35As shown, the heat exchange fluid no longer flows to the second cavity 152, but instead turns back and flows toward the radial inner side via the space between the first partition 154 and the outer ring 13, and then flows to the outlet 158 and out of the disc body 11. That is, in this case, a space is provided between the first partition 154 and the outer ring 13.

[0157] As can be seen, when the inlet annular groove 813 is located radially inward of the outlet annular groove 814, the heat exchange fluid can be guided to flow first toward the radial inner side, then toward the radial outer side, and then toward the radial inner side again, based on the first and second partitions 154 and 155 provided, which facilitates the heat exchange fluid to flow orderly through each radial portion of the disc body 11 and exchange heat with the material 20 at each radial portion, and also facilitates the heat exchange fluid to flow from the first cavity 151 to the second cavity 152 when the second cavity 152 is provided in the outer ring 13, thus facilitating the heat exchange process of the disc body 11 first and then the outer ring 13.

[0158] In the above embodiments, in order to improve the sandwich heat exchange effect, referring to Figures 30-31 In some embodiments, baffles 156 are provided in the cavity 15 to guide the heat exchange fluid entering the cavity 15 to flow turbulently. Among them, as shown, Figure 31 A plurality of baffles 156 can be arranged side by side, and adjacent two baffles 156 can be arranged on opposite side walls of the cavity 15 and partially staggered in the opposite direction of the two side walls to form a turbulent flow channel to guide the heat exchange fluid to flow turbulently in the cavity 15. For example, referring to Figure 31 In some embodiments, a plurality of sets of baffles 156 can be provided in the first cavity 151 inside the disc body 11, and each set of baffles 156 comprises a plurality of baffles 156 located at the same circumferential position. These baffles 156 at the same circumferential position are arranged side by side along the radial direction of the disc body 11, and adjacent two baffles 156 are connected to the upper and lower side walls of the first cavity 151 and arranged staggered in the upper and lower directions to form an S-shaped turbulent flow channel. Since the turbulent flow can prolong the flow time of the heat exchange fluid in the cavity 15, the heat exchange fluid can be more fully exchanged with the material 20, thus being beneficial to improve the temperature control effect on the material 20.

[0159] In addition, as another indirect heat exchange temperature control method, referring to Figure 36In some embodiments, the koji maker 10 comprises a second heat exchange system 82, which comprises a liquid pool 821 arranged below the disc 1 and used for containing liquid, and the disc 1 is at least partially immersed in the liquid of the liquid pool 821. In this way, an immersion heat exchange process can be realized, and the temperature adjustment of the material 20 can be realized by using the heat exchange between the liquid in the liquid pool 821 and the material 20 on the disc 1. This indirect heat exchange temperature adjustment method is simple and easy to implement, and can be conveniently applied regardless of whether the disc 1 rotates or not.

[0160] Next, each embodiment shown in Figures 1-42 will be further described.

[0161] First, the first embodiment shown in Figures 1-33 will be introduced.

[0162] Referring to Figures 1-2 , in this first embodiment, the koji maker 10 comprises a disc 1, a discharging mechanism 2, a feeding mechanism 3, a turning mechanism 4, a temperature adjusting device 5, a rotating disc mechanism 61, a ventilation device 7, a first heat exchange system 81, and a frame 91.

[0163] Among them, the disc 1 is rotatably arranged on the frame 91 and internally contains the material 20 to be fermented and brewed. The discharging mechanism 2 is used to transport the brewed or fermented material 20 from the disc 1 to the designated position of the next process. The feeding mechanism 3 is used to transport the material 20 to be fermented or brewed into the disc 1. The turning mechanism 4 is used to turn the material 20 on the disc 1. The temperature adjusting device 5 is used to control the temperature and turn the material 20 on the disc 1. The rotating disc mechanism 61 is used to drive the disc 1 to rotate. The ventilation device 7 is used to ventilate the koji making chamber 78 where the disc 1 is located, and the cold and hot air penetrates the material 20 to control the temperature of the material 20. The first heat exchange system 81 is used to introduce heat exchange fluid into the interlayer of the disc 1 to realize indirect heat exchange temperature control of the material 20.

[0164] In summary, the koji maker 10 of this embodiment is an assembly in which the material 20 enters the disc 1 through the feeding mechanism 3, and during the rotation of the disc 1, the brewing or fermentation process of the material is controlled by one or more of the turning mechanism 4, the temperature adjusting device 5, the ventilation device 7, and the first heat exchange system 81, and finally the fermented or brewed material 20 is transported to the next process device by the discharging mechanism 2.

[0165] Next, each component will be introduced respectively.

[0166] Figures 1-3 The structure of the disc 1 in this embodiment is shown. As Figures 1-3As shown, in this embodiment, the disc 1 is an annular groove disc, comprising a disc body 11, an inner ring 12, and an outer ring 13. A discharge port 14 is located at the center of the disc body 11. The outer ring 13 and the inner ring 12 are respectively disposed on the outer and inner rings of the disc body 11, and are inseparably connected to the disc body 11, making the entire disc 1 a single integrated structure. Thus, the disc 1, being an annular groove shape, is suitable for holding liquid, solid-liquid mixture, or solid materials 20 to complete the fermentation and brewing process of the corresponding materials 20.

[0167] Figures 1-6 The structure of the discharge mechanism 2 in this embodiment is shown. See also Figures 1-6 In this embodiment, the discharge mechanism 2 adopts a conveying method that first conveys the material to the radially inward side and then upward to complete the discharge process. It does not rotate with the disc 1 and includes a conveyor 21 and a guiding device 2b. The guiding device 2b includes a baffle plate 26, a scraper 2a, a guiding sleeve 27, a guiding plate 29, and a guiding pipe 28.

[0168] Among them, such as Figures 1-3 As shown, in this embodiment, the conveyor 21 is specifically a screw conveyor 23, which is arranged above the disc 11 and extends radially along the disc 1, from the outer ring 13 to the inner ring 12. At this time, the axial direction of the conveyor 21 is along the radial direction of the disc 1, and the conveyor 21 can rotate along its own axis to realize the radial conveying of the material 20.

[0169] At the same time, such as Figures 1-4 As shown, in this embodiment, the baffle plate 26 is arranged along the circumference of the disk 1 (which is also the circumference of the conveyor 21) on one side of the conveyor 21, and is located radially on the disk 1 at one end of the conveyor 21 near the outer ring 13. Furthermore, as... Figure 4 As shown, the baffle plate 26 in this embodiment includes a first segment 261 and a second segment 262 connected to each other. The first segment 261 extends vertically and upwards above the conveyor 21. The second segment 262 is connected to the lower end of the first segment 261 and bends towards the side where the conveyor 21 is located. The surface of the second segment 262 facing the conveyor 21 is arc-shaped, adapting to the arc-shaped surface of the conveyor 21.

[0170] like Figure 4 As shown, in this embodiment, the scraper 2a is connected to the lower end of the baffle plate 26 and extends downward relative to the baffle plate 26 and towards the conveyor 21. Specifically, as Figure 4 As shown, scraper 2a is connected to the lower end of the second section 262 of baffle plate 26, extends downward from the second section 262, and is inclined towards the side closer to conveyor 21 in a downward direction.

[0171] Combination Figures 1-3 and Figure 6As can be seen, in this embodiment, the guide sleeve 27 is sleeved on the outside of the conveyor 21 and extends from the baffle plate 26 to the inner ring 12 in the radial direction of the disc 1. Furthermore, the circumferential sidewalls of the guide sleeve 27 are completely closed; in other words, the sidewalls of the guide sleeve 27 are connected end to end in the circumferential direction to form a complete circle.

[0172] like Figure 6 As shown, in this embodiment, the guide plate 29 is connected at both ends to the sidewalls of the inner ring 12 and the guide sleeve 27, respectively, and is inclined away from the guide sleeve 27 along the direction from the radially outer side to the radially inner side of the disk 1. In other words, along the direction from the radially inner side to the radially outer side of the disk 1, the guide plate 29 is inclined towards the guide sleeve 27, and the distance between the guide plate 29 and the guide sleeve 27 gradually decreases. Furthermore, as... Figure 1 As shown, the guide plate 29 and the baffle plate 26 are arranged on both sides of the axis of the conveyor 21.

[0173] Back Figures 2-3 In this embodiment, the guide tube 28 is a U-shaped bend, one end of which is connected to the guide sleeve 27 and communicates with the inside of the guide sleeve 27, and the other end extends from above the inner ring 12 across the inner ring 12 to the inside of the inner ring 12 and communicates with the discharge port 14 located in the center of the disc 11.

[0174] And, as Figure 3 As shown, in this embodiment, the koji-making machine 10 includes a discharge lifting mechanism 22, which is driven to connect with the discharge mechanism 2 and drives the discharge mechanism 2 to lift as a whole, so as to control the conveyor 21 to contact or separate from the material 20, thereby meeting different needs at different stages.

[0175] When no material needs to be discharged, such as during feeding or fermentation, the discharge lifting mechanism 22 can drive the discharge mechanism 2 to rise, so that the discharge mechanism 2 separates from the material 20 and does not come into contact with the material 20, so as to prevent the discharge mechanism 2 from affecting the normal feeding or fermentation process. When material needs to be discharged, the discharge lifting mechanism 22 drives the discharge mechanism 2 to descend, so that the lower edge of the conveyor 21 is in close contact with the upper surface of the disc 11, so that the conveyor 21 can fully contact the material 20. At this time, the conveyor 21 is started, so that the conveyor 21 conveys the material 20 radially inward to the disc 1. The material 20 can move from the section where the baffle plate 26 is located to the section where the guide sleeve 27 is located. After the material 20 enters the guide sleeve 27, the conveyor 21 continues to convey and compress, so that the material 20 rises upward and enters the guide pipe 28, and finally falls from the end of the guide pipe 28 into the discharge port 14. It falls from the discharge port 14 to the outside of the disc 1. As the disc 1 rotates, the material 20 of the entire disc 1 can be sent to the discharge port 14, completing the discharge process.

[0176] The material 20 falling from the discharge port 14 can be caught by receiving devices such as receiving trays, and then transported by conveying equipment to the designated position in the downstream process. In this case, since the discharge port 14 is located at the center of the disc 1, the corresponding radial range is small. Therefore, the diameter of the receiving tray can be small, and it does not need to occupy a large space.

[0177] However, to further facilitate the transfer of materials to downstream processes, see [link / reference] Figures 2-3 In this embodiment, instead of a receiving tray or other receiving device below the discharge port 14, a discharge mechanism 63 is provided. This discharge mechanism 63 is located below the discharge port 14, communicates with the discharge port 14, and extends radially along the disc 1. Thus, the material 20 falling from the discharge port 14 can directly fall onto the discharge mechanism 63 and be conveyed radially outward from the disc 1. This eliminates the need for a receiving tray, saving floor space. Furthermore, since the material 20 does not need to first fall into the receiving tray and then be transferred outward, but can be directly conveyed outward by the discharge mechanism 63, material transportation is more convenient, the connection between processes is tighter, and overall production efficiency is improved.

[0178] In addition, such as Figures 2-3 As shown, in this embodiment, the discharge mechanism 2 is also equipped with a spraying device 25, which includes a spray pipe 251. The spray pipe 251 sprays liquids such as water toward the material 20 and the conveyor 21 to add liquid to the material 20, or to clean the conveyor 21, making the material 20 easier to ferment or transport, or making the conveyor 21 cleaner. Multiple nozzles can be provided on the spray pipe 251 to further improve the spraying effect.

[0179] Figures 7-8 The structure of the feeding mechanism 3 in this embodiment is shown. For example... Figures 7-8 As shown, in this embodiment, the feeding mechanism 3 is disposed above the disc 11 and does not rotate with the disc 1. It includes a first conveying device 31 and a second conveying device 32. Both the first conveying device 31 and the second conveying device 32 are disposed on a feeding rack 33 connected to the frame 91 and extend radially along the disc 1. The first conveying device 31 is fixedly disposed radially along the disc 1 and has a feeding port 34. The second conveying device 32 is disposed below the first conveying device 31 and is movably disposed radially along the disc 1. It has a feeding port 35. Specifically, as shown... Figure 8As shown, a roller 39 is provided below the second conveying device 32. The roller 39 contacts the feeding frame 33, causing the roller 39 to rotate, thereby enabling the second conveying device 32 to move radially along the disc 1 on the feeding frame 33. In this way, the second conveying device 32 can move radially relative to the first conveying device 31 along the disc 1, making the feeding mechanism 3 as a whole extendable and retractable, and able to convey the material 20 to different positions on the disc 1.

[0180] When feeding is required, material 20 falls from the previous conveying equipment into the feed inlet 34 and onto the first conveying device 31. Then, it falls from the first conveying device 31 onto the second conveying device 32 and from the material distribution port 35 of the second conveying device 32 onto the disc 1. Since the second conveying device 32 can move radially relative to the disc 1, it can convey material 20 to different radial positions on the disc 1. Furthermore, since the disc 1 rotates relative to the feeding mechanism 3, the feeding mechanism 3 can deliver material 20 to different circumferential positions on the disc 1. Thus, with the cooperation of the feeding mechanism 3 and the disc 1, material 20 can be evenly distributed onto the entire disc 1.

[0181] Among them, such as Figure 8 As shown, in this embodiment, the first conveying device 31 and the second conveying device 32 are specifically belt conveyors 36, but it can be understood that, as a variation, such as Figure 9 and Figure 10 As shown, the first conveying device 31 and the second conveying device 32 can also be a screw conveyor 37 or a scraper conveyor 38.

[0182] Figures 11-12 The structure of the material-turning mechanism 4 in this embodiment is shown. For example... Figures 11-12 As shown, in this embodiment, the material turning mechanism 4 is located above the disc 11 and does not rotate with the disc 1. It includes a material turning device 41 and a material turning lifting mechanism 42. The material turning device 41 rotates around its own rotation axis to turn the material 20, ensuring that the material 20 reaches the required temperature, humidity, and microbial environment evenly. The material turning lifting mechanism 42 is mounted on the frame 91 and is driven by the material turning device 41 to drive the material turning device 41 to rise and fall, controlling whether the material turning device 41 contacts the material 20. When the material turning device 41 descends to contact the material 20, it can turn the material 20, thus realizing the material turning function. After the material turning device 41 rises above the material 20, it no longer contacts the material 20 and can no longer turn the material 20.

[0183] During the production process, when the material turning and lifting mechanism 42 raises the material turning device 41 to the highest point, the material turning device 41 stops turning. When the material turning and lifting mechanism 42 drives the material turning device 41 to rise and fall at other heights below the highest point, the material turning device 41 can turn the material 20 at different heights.

[0184] Among them, such as Figure 11 As shown, in this embodiment, the turning device 41 is specifically a horizontal turning and throwing type turning device 43, whose own rotation axis is along the horizontal direction. However, the structure of the turning device 41 is not limited to this; for example, as a variation, such as Figures 13-14 As shown, the turning device 41 can also be a vertical spiral turning device 44, which includes multiple spiral turning components whose own rotation axis extends in the vertical direction. For example, although not shown, the turning device 41 can also be a rake-type turning device. Alternatively, depending on the characteristics of the material or the process requirements, the turning device 41 can adopt a combination of two or more of the following: a horizontal turning device 43, a vertical spiral turning device 44, or a rake-type turning device.

[0185] Figure 15 The structure of the temperature control device 5 in this embodiment is shown. See also Figure 15 In this embodiment, the temperature control device 5 is mounted on the frame 91 and does not rotate with the disc 1. It includes a support 57 and a heat exchanger 51. The support 57 is fixedly connected to the frame 91. The heat exchanger 51 is mounted on the support 57 and includes a main pipe 52 and branch pipes 53. The main pipe 52 has a heat exchange medium inlet 54 and a heat exchange medium outlet 55, which allow the heat exchange medium to enter and exit the heat exchanger 51, respectively. Multiple branch pipes 53 are arranged radially along the disc 1 and communicate with the main pipe 52, extending downward from the main pipe 52 to contact the material 20. Since the heat exchanger 51 is supplied with heat exchange medium, when the heat exchanger 51 contacts the material 20 through the branch pipes 53, the heat exchange medium in the heat exchanger 51 can exchange heat with the material 20, thereby regulating the temperature of the material 20. Furthermore, since the disc 1 rotates but the heat exchanger 51 does not rotate with it, there is a relative rotation between the two. Therefore, the heat exchanger 51 can also function as a material turning device. As can be seen, the heat exchanger 51 in this embodiment can both control the temperature and turn the material, thus serving two purposes in one machine.

[0186] Figures 16-17 The structure of heat exchanger 51 is further illustrated. For example... Figures 16-17 As shown, in this embodiment, the branch pipe 53 of the heat exchanger 51 is generally cylindrical, hollow inside, and has a uniform cross-sectional dimension from top to bottom. Of course, the shape of the branch pipe 53 can also have other variations. For example, by... Figures 18-19 As can be seen, in some embodiments, the branch pipe 53 is generally U-shaped, hollow inside, and has a consistent cross-sectional size from top to bottom. For example, from... Figures 20-21 As can be seen, in other embodiments, the branch pipe 53 is generally rake-shaped, hollow inside, and its cross-section gradually increases from top to bottom. For example, as... Figures 22-23 As shown, in some other embodiments, the branch pipe 53 is generally plow-shaped, hollow inside, with a consistent cross-sectional size from top to bottom, and a protrusion 56 is provided on the outer surface of the branch pipe 53. The protrusion 56 is generally plow-shaped, with a smooth upper part and a sharp lower part.

[0187] Figures 24-25 The structure of the turntable mechanism 61 in this embodiment is shown. See also Figures 24-25 In this embodiment, the disk 1 is rotatably mounted on the frame 91 and driven to rotate by the turntable mechanism 61. Specifically, the center of the disk 1 is supported by a central bearing 614 (e.g., a centering rolling bearing), and the outer edge is supported by a first support roller 613, so that the disk 1 can rotate relative to the frame 91 about a longitudinal axis of rotation located at the center of the disk 1. The turntable mechanism 61 includes a turntable drive mechanism 611 and a first transmission mechanism 612. The turntable drive mechanism 611 is driven to rotate the disk 1 via the first transmission mechanism 612. The turntable drive mechanism 611 is located on the outer edge of the disk 1 and includes one, two, or more motors. The first transmission mechanism 612 is located on the outer edge of the disk 1 and includes gears and teeth or pins located around the entire circumference of the disk 1. The teeth or pins are driven to rotate the turntable drive mechanism 611 via the gears, so that when the turntable drive mechanism 611 is activated, it can drive the entire disk 1 to rotate automatically about the longitudinal axis of rotation. In this way, when the turntable drive mechanism 611 is started, it can drive the entire disc 1 to rotate automatically around the longitudinal rotation axis.

[0188] Since the disc 1 can rotate around the longitudinal axis of rotation under the action of the turntable mechanism 61, while the discharge mechanism 2, the feeding mechanism 3, the turning mechanism 4 and the temperature control device 5 do not rotate around the longitudinal axis of rotation, the relative rotation between the discharge mechanism 2, the feeding mechanism 3, the turning mechanism 4 and the temperature control device 5 and the disc 1 around the longitudinal axis of rotation can be realized. As the disc 1 rotates, the discharge mechanism 2, the feeding mechanism 3, the turning mechanism 4 and the temperature control device 5 can reach different circumferential positions of the disc 1 and perform discharge, feeding, turning and temperature control at different circumferential positions, ultimately realizing the discharge, feeding, turning and temperature control of the disc 1 around the entire circumference.

[0189] The rotation of disc 1 not only facilitates the continuous feeding, discharging, and turning of material throughout the entire cycle, but also promotes the uniform fermentation of material 20. Furthermore, if material 20 needs to be kept still during fermentation, disc 1 can remain stationary and not rotate throughout the entire fermentation process or for a certain period of time during fermentation.

[0190] Figures 26-27 The structure of the ventilation device 7 in this embodiment is shown. See also Figures 26-27, in this embodiment, the koji-making machine 10 is in a closed koji-making chamber 78, and the ventilation device 7 ventilates the koji-making chamber 78, allowing hot and cold air to pass through the material 20 and directly exchange heat with the material 20 to adjust the temperature of the material 20. Among them, the ventilation device 7 includes a fan 71, an air duct 72, a heat exchanger 73, and a regulating valve 74. The fan 71 is connected to the inside and outside through the air duct 72 to drive air into the koji-making chamber 78. The air duct 72 is provided with a regulating valve 74 and a heat exchanger 73. The regulating valve 74 adjusts the air volume. The heat exchanger 73 adjusts the temperature of the air flowing into the room.

[0191] As a variant of the Figures 26-27 shown ventilation device 7, the heat exchanger 73 may not be provided in the air duct 72, and instead, a heater or hot steam may be used to heat the air, or cooling water or a refrigeration air conditioner may be used to cool the air. Alternatively, the air duct 72 and the heat exchanger 73, etc. may not be provided, and the fan 71 may be directly connected to the room. Additionally, as Figures 28-29 shown, when the koji-making chamber 78 is a non-closed space and the koji-making chamber 78 is connected to the outside through a window 75, the ventilation device 7 may only include a fan 71, and during the production process, the ventilation condition may be controlled by controlling the opening and closing of the fan 71 and the opening degree of the window 75.

[0192] Figures 30-33 shows the structure of the first heat exchange system 81 and the disc 1 supporting the first heat exchange system 81 in this embodiment. As Figures 30-33 shown, in this embodiment, a first chamber 151 and a second chamber 152 are respectively provided in the disc body 11 and the outer ring 13 of the disc 1, making both the disc body 11 and the outer ring 13 into sandwich structures. The first heat exchange system 81 is arranged below the disc body 11 and is used to introduce a heat exchange fluid into the first chamber 151 and the second chamber 152 to utilize the heat exchange between the heat exchange fluid and the material 20 to adjust the temperature of the material 20.

[0193] Among them, as Figures 30-31As shown, the first heat exchange system 81 of this embodiment includes a first shell 811, a second shell 812, an inlet pipe 81a, and an outlet pipe 81b. The first shell 811 is fixedly disposed on the lower surface of the disk 11, allowing it to rotate with the disk 1. The second shell 812 is disposed below the first shell 811, and a bearing 816 is provided between it and the first shell 811. The outer ring of the bearing 816 engages with the second shell 812, and the inner ring engages with the first shell 811, allowing the second shell 812 to remain stationary while the first shell 811 and the disk 1 rotate. A sealing ring 815 is provided on the second shell 812 to seal the gap between the second shell 812 and the first shell 811, preventing leakage of the heat exchange fluid. The inlet pipe 81a and the outlet pipe 81b are both connected to the second shell 812 and communicate with the entire circumference of the first cavity 151 inside the disk 11 through the second shell 812 and the first shell 811. Both the inlet pipe 81a and the outlet pipe 81b are equipped with control valves 817 to regulate the flow rate of the heat exchange fluid. Although not shown, it is easy to understand that pumps can be installed on the inlet pipe 81a and / or the outlet pipe 81b to drive the flow of the heat exchange fluid.

[0194] Specifically, such as Figure 31 As shown, in this embodiment, the second shell 812 is provided with an inlet 818 and an outlet 819 separated from each other. An inlet pipe 81a and an outlet pipe 81b are respectively connected to the inlet 818 and the outlet 819. In the radial direction of the disk 1, the inlet 818 is closer to the inner ring 12 than the outlet 819. At this time, the inlet 818 is located radially inside the outlet 819, and the inlet pipe 81a is located radially inside the outlet pipe 81b. Meanwhile, as... Figure 31 As shown, the first shell 811 is provided with an inlet annular groove 813 and an outlet annular groove 814 separated from each other. Both the inlet annular groove 813 and the outlet annular groove 814 are annular grooves, arranged sequentially from the inner ring 12 to the outer ring 13, and respectively connected to the inlet pipe 81a and the outlet pipe 81b through the inlet port 818 and the outlet port 819, and both are connected to the first cavity 511 inside the disk body 11. In this way, the heat exchange fluid flowing from the inlet pipe 81a to the disk 1 can flow into the disk body 11 sequentially through the inlet port 818 and the inlet annular groove 813, and the heat exchange fluid after flowing through the disk body 11 and the outer ring 13 can flow out sequentially through the outlet annular groove 814, the outlet port 819 and the outlet pipe 81b.

[0195] Since the second shell 812 connected to the inlet pipe 81a and the outlet pipe 81b does not rotate with the disk 1, the inlet pipe 81a and the outlet pipe 81b do not rotate during the rotation of the disk 1. Therefore, the inlet pipe 81a and the outlet pipe 81b will not have a tangling problem due to the rotation of the disk 1.

[0196] Furthermore, since the inlet annular groove 813 and the outlet annular groove 814 are arranged along the entire circumference of the disk 1 and are always in communication with the disk 1, the flow of the heat exchange fluid is not affected by the rotation of the disk 1. No matter what angle the disk 1 rotates to, the heat exchange fluid can enter and exit the disk body 11 through the inlet annular groove 813 and the outlet annular groove 814 to exchange heat with the material 20.

[0197] In order to ensure that the inlet annular groove 813 and the outlet annular groove 814 remain in communication with the disk 1 during its rotation, combined with Figures 31-33 As can be seen, in this embodiment, the bottom wall of the disk body 11 is provided with multiple sets of inlets 157 and outlets 158. These multiple sets of inlets 157 and outlets 158 are arranged at intervals along the circumference of the disk body 11. In each set of inlets 157 and outlets 158, the inlet 157 and outlet 158 ​​are respectively connected to the inlet annular groove 813 and the outlet annular groove 814. In this way, the inlet annular groove 813 and the outlet annular groove 814 can always be connected to the disk 1 during the rotation of the disk 1.

[0198] Specifically, such as Figures 32-33 As shown, in this embodiment, the first cavity 151 inside the disk 11 is divided into multiple heat exchange chambers 153. These multiple heat exchange chambers 153 are distributed along the entire circumference of the disk 11, and each heat exchange chamber 153 has a set of inlets 157 and outlets 158 on its bottom wall, so that each heat exchange chamber 153 is connected to the inlet annular groove 813 and the outlet annular groove 814. Furthermore, by Figures 32-33 As can be seen, in this embodiment, each heat exchange chamber 153 is provided with a first partition 154 and a second partition 155. The first partition 154 extends radially along the disk 1, dividing the heat exchange chamber 153 into a first space 15a and a second space 15b located circumferentially on both sides of the first partition 154. The inlet 157 and the outlet 158 ​​are located in the first space 15a. The second partition 155 is disposed in the first space 15a and is located radially between the inlet 157 and the outlet 158, separating the inlet 157 and the outlet 158 ​​to prevent the heat exchange fluid flowing into the heat exchange chamber 153 from the inlet 157 from bypassing the disk body 11 and flowing directly out from the outlet 158. Furthermore, as... Figure 33 As shown, in this embodiment, there is no gap between the first partition 154 and the outer ring 13, but there is a gap between it and the inner ring 12, so that the first space 15a and the second space 15b are connected on the side near the inner ring 12, but isolated and not connected on the side near the outer ring 13. Meanwhile, as... Figure 33As shown, in this embodiment, the first space 15a is connected at its radially outer end to the outlet O of the second cavity 152 located inside the outer ring 13, and the second space 15b is connected at its radially outer end to the inlet I of the second cavity 152. Furthermore, both the first space 15a and the second space 15b are provided with multiple baffles 156, forming baffled flow channels in both spaces, allowing the heat exchange fluid to flow in a tortuous manner within both spaces.

[0199] Based on the above configuration, during the rotation of the disk 1, the heat exchange fluid flowing from the inlet pipe 81a into the inlet annular groove 813 can flow into each heat exchange chamber 153 via the inlet 157. The heat exchange fluid entering each heat exchange chamber 153 first enters the first space 15a. In the first space 15a, due to the obstruction of the second partition 155, the heat exchange fluid cannot flow radially outward towards the outlet 158, but can only flow radially inward towards the disk 1. When it reaches the inner end of the first partition 154, it flows into the second space 15b through the gap between the first partition 154 and the inner ring 12. The flow reverses in the second space 15b and changes to flow radially outward towards the disk 1. When the heat exchange fluid flows radially outward towards the disk 1 in the second space 15b to the outer end of the first partition 154, since there is no gap between the first partition 154 and the outer ring 13, the heat exchange fluid will not flow directly back to the first space 15a. Instead, it will flow into the second cavity 152 through the inlet I of the second cavity 152, and after flowing through the second cavity 152, it will flow back to the first space 15a from the outlet O of the second cavity 152. Then it will flow to the outlet 158, from the outlet 158 ​​to the discharge ring groove 814, and finally to the discharge pipe 81b.

[0200] As can be seen, based on the above configuration, the heat exchange fluid can first flow through the disk 11 and then through the outer ring 13. When flowing through the disk 11, it can first flow radially inward and then radially outward. The entire flow process is orderly and controllable, and the temperature of the material 20 at different radial and height positions on the disk 1 can be controlled in an orderly manner. This is beneficial to ensure that the material 20 on the entire disk 1 reaches a temperature that better meets the process requirements.

[0201] Figures 34-35 The diagram illustrates the flow path inside the disk body 11 when the second cavity 152 is not provided within the outer ring 13. For example... Figures 34-35As shown, when the second cavity 152 is not provided in the outer ring 13, multiple heat exchange cavities 153 can still be provided in the disc body 11, and the first partition 154 and the second partition 155 can still be provided in the heat exchange cavities 153 to divide the heat exchange cavities 153 into a first space 15a and a second space 15b. The main difference is that the first space 15a and the second space 15b are no longer connected to the interior of the outer ring 13 at the end near the outer ring 13, but are separated from the outer ring 13. By setting a gap between the outer ring 13 and the first partition 154, the second space 15b is connected to the part of the first space 15a located on the outlet 158 ​​side, so that the heat exchange fluid flowing into the second space 15b no longer flows into the outer ring 13, but flows directly back into the first space 15a from the gap between the outer ring 13 and the first partition 154 and flows out from the outlet 158. In this case, no heat exchange occurs between the heat exchange fluid and the material 20 at the outer ring 13. The heat exchange fluid only flows back and forth in the disc 11 to exchange heat with the material 20.

[0202] As Figures 30-35 The replacement of the first heat exchange system 81 shown is as follows: Figure 36 As shown, the koji-making machine 10 may include a second heat exchange system 82, which includes a liquid storage tank 821, a level gauge 822, an inlet valve 823, and an outlet valve 824. The liquid storage tank 821 is located below the disc 1 and contains liquids such as water. The disc 1 is at least partially immersed in the liquid in the liquid storage tank 821, allowing the liquid in the tank 821 to exchange heat with the material 20 on the disc 1, changing the temperature of the material 20 and achieving an immersion-type temperature control process. The level gauge 822 is located on the liquid storage tank 821 to detect the liquid level in the tank 821, preventing excessive or insufficient liquid levels. The inlet valve 823 and the outlet valve 824 are respectively located on the inlet and outlet pipes of the liquid storage tank 821 to control whether liquid is added to or discharged from the tank 821.

[0203] Next, we will introduce... Figures 37-42 The second embodiment is shown.

[0204] like Figures 37-42 As shown, in this second embodiment, the koji-making machine 10 still includes a disc 1, a discharge mechanism 2, a feeding mechanism 3, a turning mechanism 4, a temperature control device 5, a ventilation device 7, a first heat exchange system 81, and a frame 91, but no longer includes a turntable mechanism 61, instead including a rotating frame 92 and a rotating frame mechanism 93. This is because this embodiment differs from the aforementioned... Figures 1-37 A key difference in the first embodiment shown is that the disc 1 no longer rotates, but instead the discharge mechanism 2, the feeding mechanism 3, the turning mechanism 4, and the temperature control device 5 rotate.

[0205] The following section will mainly introduce the differences between the second embodiment and the first embodiment described above. For other aspects not described, please refer to the description of the first embodiment described above for understanding.

[0206] like Figures 37-40 As shown, in this second embodiment, although the disc 1 is still annular, it is no longer rotatably mounted on the frame 91, but is non-rotatably mounted on the frame 91. In this case, in order to achieve relative rotation between the discharge mechanism 2, the feeding mechanism 3, the tilting mechanism 4, and the temperature control device 5 and the disc 1, as follows: Figures 37-40 As shown, the koji-making machine 10 includes a rotating frame 92, which is rotatably mounted. The discharge mechanism 2, the feeding mechanism 3, the turning mechanism 4, and the temperature control device 5 are all mounted on the rotating frame 92. The koji-making machine 10 also includes a rotating frame mechanism 93, which is drivenly connected to the rotating frame 92 to drive the rotating frame 92 to rotate, thereby driving the discharge mechanism 2, the feeding mechanism 3, the turning mechanism 4, and the temperature control device 5 to rotate.

[0207] Specifically, such as Figures 37-40 As shown, in this embodiment, the center of the rotating frame 92 is supported by a self-aligning bearing 934, and the edge of the rotating frame 92 is supported by a second support roller 933, thereby enabling the rotating frame 92 to be rotatable. The rotating frame mechanism 93 includes a frame drive mechanism 931 and a second transmission mechanism 932. The frame drive mechanism 931 is driven to rotate the rotating frame 92 via the second transmission mechanism 932. A track 935 is provided below the second support roller 933 to guide the rotation of the rotating frame 92. The track 935 can be fixed to the frame 91. Furthermore, the frame drive mechanism 931 is located on the outer edge of the rotating frame 92 and includes one, two, or more motors. The second transmission mechanism 932 is located on the outer edge of the disk 1 and is a pin-driven mechanism.

[0208] Based on the above settings, when the frame drive mechanism 931 is started, it can drive the rotating frame 92 around the longitudinal rotation axis located at the center of the disk 1, so that the discharge mechanism 2, feeding mechanism 3, turning mechanism 4 and temperature control device 5 located on the rotating frame 92 can rotate together with the rotating frame 92, thereby realizing the relative rotation between the discharge mechanism 2, feeding mechanism 3, turning mechanism 4 and temperature control device 5 and the disk 1.

[0209] By setting up a rotating frame 92, the relative rotation between the discharge mechanism 2, the feeding mechanism 3, the turning mechanism 4, the temperature control device 5, and the disc 1 can be achieved, which is simpler and more convenient.

[0210] Furthermore, since disk 1 does not rotate, it avoids the problem of pipe entanglement, thus simplifying the structure of the first heat exchange system 81. For example... Figure 41As shown, in this second embodiment, only the disc body 11 of the disc 1 adopts a sandwich structure, with a first cavity 151 inside. Neither the inner ring 12 nor the outer ring 13 has a sandwich structure. Furthermore, the first heat exchange system 81 no longer includes a first shell 811 and a second shell 812 that can rotate relative to each other; instead, it includes an inlet pipe 81a and an outlet pipe 81b directly connected to the disc body 11. Since the disc 1 does not rotate, even if the inlet pipe 81a and the outlet pipe 81b are directly connected to the disc body 11, the inlet pipe 81a and the outlet pipe 81b will not experience rotation or entanglement, making it simple and convenient.

[0211] Figure 42 A schematic diagram of the flow path on the disk body 11 in this embodiment is shown. For example... Figure 42 As shown, in this embodiment, the first cavity 151 within the disk 11 is still divided into multiple heat exchange chambers 153, which are arranged circumferentially along the disk 1, covering the entire circumference of the disk 11. Furthermore, each heat exchange chamber 153 has an inlet 157 and an outlet 158 ​​on its bottom wall, which are respectively connected to the inlet pipe 81a and the outlet pipe 81b. Simultaneously, each heat exchange chamber 153 is provided with multiple baffles 156, forming a baffled flow channel. In this way, the heat exchange fluid in the inlet pipe 81a can enter the heat exchange chamber 153 through the inlet 157, and after multiple deflections within each heat exchange chamber 153, flow out from the outlet 158 ​​and into the outlet pipe 81b, ultimately achieving temperature regulation of the material 20 on the entire disk 11.

[0212] In summary, the koji-making machine 10 provided in this embodiment can easily realize the discharge of material from the annular groove disc, and can more effectively control the material temperature to achieve better fermentation and brewing results.

[0213] The above description is merely an exemplary embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
