[0090] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits 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 creative efforts belong to the scope of protection of the present disclosure.

[0091] For technologies, methods, and devices known to those of ordinary skill in the relevant fields, detailed discussions may not be made, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0092] In the description of the present disclosure, it should be understood that when using terms such as "first" and "second" to limit components, it is only for the convenience of distinguishing the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present disclosure.

[0093] In the description of the present disclosure, it should be understood that the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship when the koji-making machine is placed normally. Among them, the direction same as the gravity direction is the lower direction, and the direction opposite to the gravity direction is the upper direction; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0094] In addition, the technical features involved in different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0095] Figures 1 - 45 The structure of the koji-making machine of the present disclosure is exemplarily shown. In order to clearly show each structure, some structures are simplified or omitted in some figures.

[0096] See Figures 1 - 45 , the koji-making machine 10 includes a disc 1, a discharging mechanism 2, a feeding mechanism 3, a material-turning mechanism 4 and a frame 91.

[0097] Among them, the disc 1 is used to hold the material 20 and provide a fermentation place for the material 20. The discharging mechanism 2 is used to convey the brewed or fermented material 20 from the disc 1 to a specified position in the downstream process. The feeding mechanism 3 is used to send the material 20 to be fermented into the disc 1. The material-turning mechanism 4 is used to stir the material 20 on the disc 1 during the fermentation process to make the fermentation more uniform and sufficient. The frame 91 is used to provide support for the disc 1.

[0098] 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 material-turning mechanism 4 are arranged above the disc 1 and are rotatably arranged relative to the disc 1 to utilize the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the material-turning mechanism 4 and the disc 1 to achieve discharging, feeding and material-turning in the entire circumferential direction of the disc 1. Among them, in order to achieve the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the material-turning mechanism 4 and the disc 1, the disc 1 can be rotated while the discharging mechanism 2, the feeding mechanism 3 and the material-turning mechanism 4 do not rotate, or alternatively, the discharging mechanism 2, the feeding mechanism 3 and the material-turning mechanism 4 can be rotated while the disc 1 does not rotate. Here, the rotation of the disc 1, the discharging mechanism 2, the feeding mechanism 3 and the material-turning mechanism 4 all 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 hereinafter.

[0099] Among them, seeFigures 2 - 3 In the embodiment of the present disclosure, the disc 1 includes a disc body 11, an inner ring 12 and an outer ring 13. The inner ring 12 and the outer ring 13 are respectively arranged on the inner ring and the outer ring of the disc body 11, and both extend upward from the disc body 11 to form the inner wall and the outer wall of the disc 1, so that the disc 1 is in the shape of a ring groove as a whole.

[0100] Compared with the disc 1 in the related art that is not in the shape of an annular groove, the disc 1 in the shape of an annular groove has a wider application range, because the disc 1 in the shape of an annular groove can be used not only for the fermentation of solid materials, but also for the fermentation of liquid or solid-liquid mixed materials, providing an equipment basis for the fermentation of liquid-containing materials. When the disc 1 is in the shape of an annular groove, its outer ring 13 and inner ring 12 can block the material 20, preventing the material 20 from falling from the outer edge or inner edge of the disc body 11, especially when the material 20 contains liquid, the outer ring 13 and the inner ring 12 can prevent the material 20 from flowing from the radial inside and radial outside to the outside of the disc body 11, so that the material 20, especially the material 20 containing liquid, can be fermented and brewed more conveniently.

[0101] However, the disc 1 with an annular groove has the problem of difficulty in discharging. The disc 1 without an annular groove can conveniently discharge the material from the radial side of the disc 1. For example, for the disc 1 without an outer ring 13, a discharging method of discharging the material from the radial outside (which can be called the outer ring discharging method) is usually adopted, that is, after the material has completed fermentation, the discharging mechanism 2 will transport the material to the radial outside of the disc 1 and discharge the material from the radial outside of the disc 1. Since the outer ring 13 is not provided on the outer ring of the disc body 11, under the action of the discharging mechanism 2, the material 20 can directly fall from the outer edge of the disc body 11 to achieve the outer ring discharging. However, for the disc 1 with an annular groove, since the outer edge and inner edge of the disc body 11 are respectively provided with an outer ring 13 and an inner ring 12, the outer ring 13 and the inner ring 12 will block the discharge of the material 20. Therefore, it is difficult to directly use the conventional discharging mechanism 2 to discharge the material from the radial side of the disc body 11.

[0102] Conventional discharging mechanism 2 usually directly uses a screw or scraper conveyor to discharge materials. When discharging is required, the screw or scraper conveyor is in contact with the disc body 11 and conveys the material 20 by rotating around its own axis. This conventional discharging mechanism 2 can discharge materials smoothly for non-grooved discs 1. However, for grooved discs 1, materials transported by the screw or scraper conveyor will be blocked by the inner ring 12 and the outer ring 13 during the discharging process, so materials cannot be discharged smoothly.

[0103] It can be seen that the discharging problem is an important issue restricting the development of the ring-grooved disc koji making machine and needs to be solved urgently.

[0104] For the above situation, see Figures 1 - 7, in an embodiment of the present disclosure, at least one of the inner ring 12 and the outer ring 13 is provided with an openable and closable discharge door 16, and the discharging mechanism 2 includes a first baffle 26 and a second baffle 27. Among them, both the first baffle 26 and the second baffle 27 extend along the radial direction of the disk 1. The first baffle 26 is non-rotatably arranged relative to the disk 1 and is located on one side of the center of the discharge door 16 along the circumferential direction of the disk 1. The second baffle 27 is rotatably arranged relative to the disk 1 and is located on one side of the first baffle 26 along the circumferential direction of the disk 1.

[0105] Based on the above settings, since the first baffle 26 is non-rotatable relative to the disk 1, the relative position between the first baffle 26 and the discharge door 16 remains unchanged all the time. The first baffle 26 is always located on one side of the center of the discharge door 16 along the circumferential direction of the disk 1. At the same time, since the second baffle 27 rotates relative to the disk 1, the second baffle 27 can rotate relative to the first baffle 26. In this way, when the disk 1 rotates around the longitudinal center line of the disk 1 or the second baffle 27 rotates around the longitudinal center line of the disk 1, the second baffle 27 can gradually approach the first baffle 26 and push the material 20 on the disk 1 towards the first baffle 26. Since the material level of the material 20 can rise as the distance between the second baffle 27 and the first baffle 26 decreases and reaches the height position where the discharge door 16 is located, the discharge door 16 can be opened to discharge the material.

[0106] When discharging is required, the discharge door 16 can be opened, and the first baffle 26 and the second baffle 27 of the discharging mechanism 2 are brought into contact with the material 20 on the disk 1. In this way, when the disk 1 rotates relative to the second baffle 27, the second baffle 27 can rotate relative to the first baffle 26 and push the material 20 towards the first baffle 26. As the relative rotation angle between the disk 1 and the second baffle 27 increases, the area of the fan-shaped region between the second baffle 27 and the first baffle 26 gradually decreases, and the material level of the material 20 gradually rises. When the material 20 reaches the height position where the discharge door 16 is located, the material 20 can flow out from the discharge door 16. In this way, as the disk 1 rotates relative to the second baffle 27, the material 20 will continuously flow out from the discharge door 16 until the second baffle 27 is close to the first baffle 26, that is, the discharging is completed.

[0107] Among them, referring to Figure 41 , when the discharge door 16 is arranged on the outer ring 13, the material 20 can be pushed and piled up during the relative rotation of the first baffle 26 and the second baffle 27, and reaches the outside of the outer ring 13 (that is, the side of the outer ring 13 away from the longitudinal center line of the disk 1) through the opening corresponding to the opened discharge door 16 on the outer ring 13. At this time, as Figure 41As shown, a discharge chute 17 can be provided at a position outside the outer ring 13 and below the discharge door 16, so that the material 20 falling from the discharge door 16 can fall under the guidance of the discharge chute 17 to achieve outer ring discharge. This outer ring discharge method is particularly suitable for the case where the disk 1 does not rotate. Because when the disk 1 does not rotate, the discharge door 16 on the outer ring 13 can be maintained at a fixed circumferential position, so that the material 20 can be discharged concentratedly from this fixed circumferential position, rather than discharging along the entire circumference. In this case, it is convenient to collect the material 20 falling during the outer ring discharge process. For example, when using a receiving device such as a receiving tray below the material dropping point to receive the material, the receiving device only needs to have a smaller size, rather than surrounding the entire outer circumference with a larger diameter, so the cost is lower and the floor area is smaller.

[0108] And referring to Figures 3 - 7 , when the discharge door 16 is provided on the inner ring 12, the material 20 can be pushed and piled up during the relative rotation of the first baffle 26 and the second baffle 27, and enter the inner side of the inner ring 12 (that is, the side of the inner ring 12 close to the longitudinal center line of the disk 1) through the opening corresponding to the opened discharge door 16 on the inner ring. At this time, as Figure 5 shown, a discharge port 14 can be provided at the center of the disk body 11, so that the material 20 entering the inner side of the inner ring 12 through the opening at the discharge door 16 can fall from the discharge port 14 to achieve central discharge. This central discharge method has a wider application range and can be conveniently used whether the disk 1 rotates or not. Because, compared with the outer diameter of the outer ring of the disk 1, the inner diameter of the inner ring of the disk 1 is smaller, and the outlet of the discharge port 14 located at the center of the disk body 11 can be smaller. Therefore, no matter whether the disk 1 rotates or not, it is very convenient to receive the material 20 falling from the discharge port 14. For example, when using a receiving device such as a receiving tray below the discharge port 14 to receive the material, the receiving device only needs to have a smaller diameter, so the cost is lower and the floor area is smaller.

[0109] It can be seen that in the above setting method, the discharging mechanism 2 can push and pile up the material 20 on the disk 1, so that the material 20 flows out from the opened discharge door 16. In this way, the material 20 can no longer be blocked by the inner ring 12 or the outer ring 13, and can be discharged conveniently, thus being able to skillfully solve the discharging problem of the annular groove-shaped disk, which is beneficial to the popularization and application of the annular groove-shaped disk and convenient for the fermentation and brewing of liquid-containing materials.

[0110] To further facilitate discharging, referring to Figures 2 - 7 , in some embodiments, the discharging mechanism 2 further includes a conveyor 21. The conveyor 21 is located circumferentially on the disk 1 between the first baffle 26 and the second baffle 27, and conveys the material 20 between the first baffle 26 and the second baffle 27 towards the discharge door 16. Among them, the conveyor 21 can be various conveyors such as a screw conveyor 23 or a scraper conveyor.

[0111] Based on the above settings, when the first baffle 26 and the second baffle 27 rotate relative to each other, and the area of the fan-shaped region between the two gradually decreases and the material level gradually rises, the conveyor 21 can further convey the material 20 between the first baffle 26 and the second baffle 27 towards the discharge door 16. In this case, the material 20 can move towards the discharge door 16 not only under the pushing force generated by the relative rotation of the first baffle 26 and the second baffle 27, but also under the action of the conveyor 21. Therefore, discharging can be carried out more efficiently and thoroughly, effectively improving the discharging efficiency and the cleanliness of discharging.

[0112] In the foregoing embodiments, in order to facilitate the opening and closing of the discharge door 16, refer to Figure 3 , the koji-making machine 10 may include a door-opening mechanism 62. The door-opening mechanism 62 is drivingly connected to the discharge door 16 and drives the discharge door 16 to open and close. In this way, under the action of the door-opening mechanism 62, the discharge door 16 can be automatically opened and closed, which is beneficial to improving the overall automation degree of the koji-making machine 10 and the working efficiency of the koji-making machine 10.

[0113] Refer to Figure 2 , in some embodiments, the koji-making machine 10 includes a discharge lifting mechanism 22. The discharge lifting mechanism 22 is drivingly connected to the discharge mechanism 2 and drives the discharge mechanism 2 to lift relative to the disk 1. In this way, when discharging is not required, the discharge lifting mechanism 22 can be used to drive the discharge mechanism 22 to rise to prevent the discharge mechanism 22 from affecting the normal feeding and fermentation and brewing processes, and when discharging is required, the discharge lifting mechanism 22 can be used to drive the discharge mechanism 22 to descend so that the discharge mechanism 22 contacts the material 20 to facilitate discharging.

[0114] In addition, refer to Figure 2 , in some embodiments, the koji-making machine 10 includes a spraying device 25. The spraying device 25 is used to spray liquid onto the material 20 on the disk 1 and / or the discharge mechanism 2.

[0115] Spraying liquid onto the material 20 on the disk 1 by using the spraying device 25 facilitates meeting the fermentation and brewing requirements and conveying requirements of the material when needed. For example, some materials 20 need to add water or other liquids during the fermentation and brewing process to ferment well. Therefore, spraying liquid onto the material 20 on the disk 1 by using the spraying device 25 can better meet the technological requirements for the fermentation and brewing of these materials 20; for another example, some materials 20 are restricted by their own characteristics and are difficult to convey without dilution. Therefore, spraying liquid onto the material 20 on the disk 1 by using the spraying device 25 can better meet the conveying requirements of these materials 20. By diluting these materials 20, the conveying of these materials can be facilitated, for example, facilitating the discharging of these materials 20.

[0116] By using the spraying device 25 to spray liquid onto the discharging mechanism 2, the cleaning of the discharging mechanism 2 can be achieved, which is beneficial to maintaining the cleanliness of the discharging mechanism 2.

[0117] It can be seen that based on the provided spraying device 25, by spraying liquid onto the material 20 and / or the discharging mechanism 2, the requirements of the fermentation and brewing process, the material conveying process, and the equipment cleaning process can be better met.

[0118] Among them, the spraying device 25 can be arranged on the discharging mechanism 2. In this way, the spraying device 25 can not only conveniently spray liquid onto the discharging mechanism 2 when the discharging mechanism 2 needs to be cleaned, but also conveniently spray liquid onto the material 20 during the fermentation and brewing process or the discharging process.

[0119] In addition, in the related art, during the fermentation and brewing process, usually only the direct ventilation method is adopted to adjust the temperature of the material 20. The temperature adjustment method is relatively single, and the temperature adjustment effect also needs to be improved, which affects the overall fermentation and brewing effect. In view of this situation, the embodiments of the present disclosure also improve the temperature adjustment method of the material 20, so that the temperature adjustment method is no longer limited to the direct ventilation heat exchange method, but can also adopt the indirect heat exchange method to adjust the material temperature.

[0120] As one of the indirect heat exchange temperature adjustment methods, refer to Figure 16 , 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. The heat exchanger 51 is rotatably arranged relative to the disk 1 and extends into the material 20 on the disk 1.

[0121] The heat exchanger 51 is a heat exchanger with a heat exchange medium (such as a liquid like water) flowing inside. Therefore, by extending it into the material 20, the heat exchange between the material 20 and the heat exchange medium can be realized, and thus the temperature of the material 20 can be adjusted to meet the temperature requirements of the fermentation and brewing process.

[0122] Moreover, since the heat exchanger 51 is rotatably arranged relative to the disk 1, the heat exchanger 51 can adjust the temperature of the material 20 at different circumferential positions on the disk 1 to meet the temperature adjustment requirements of the material 20 on the entire disk 1. At the same time, the relative rotation between the heat exchanger 51 and the disk 1 also causes a relative movement between the heat exchanger 51 and the material 20. In this way, the heat exchanger 51 can play a certain stirring role on the material 20, so that the heat exchanger 51 can have both the temperature adjustment function and the material turning function.

[0123] It can be seen that based on the provided heat exchanger 51, the temperature control device 5 can achieve indirect heat exchange, enriching the temperature control methods of the koji-making machine 10 and making the koji-making machine 10 no longer limited to the direct ventilation heat exchange method. Moreover, based on the provided heat exchanger 51, the temperature control device 5 can not only control the temperature of the material, but also turn the material, serving two purposes with a single machine and having rich functions.

[0124] Among them, the temperature control device 5 can move up and down relative to the disc 1 to control contact with the material 20 only when needed.

[0125] The temperature control device 5 can achieve the function of turning the material only by relying on the relative movement with the disc 1. In this case, the stirring intensity of the temperature control device 5 is smaller than that of the conventional turning mechanism 4 that both revolves around the disc 1 and rotates around its own axis. Therefore, it is especially suitable for materials 20 that are not suitable for intense stirring. During the fermentation and brewing process of some materials 20, if there is intense stirring, it may affect the fermentation and brewing effect. In this case, the temperature control device 5 can be used to achieve the function of turning the material to meet the requirements of the material 20 for a lower-intensity turning process.

[0126] When the koji-making machine 10 includes both the temperature control device 5 and the turning mechanism 4, the temperature control device 5 can work together with the turning mechanism 4 to meet more diverse turning requirements and enhance the working flexibility of the koji-making machine 10. For example, when the material 20 requires intense stirring, the turning mechanism 4 can be started for stirring, or the temperature control device 5 and the turning mechanism 4 can be used together for stirring. When the material 20 requires non-intense stirring, only the temperature control device 5 can be used for turning, and the turning mechanism 4 is no longer started.

[0127] As another indirect heat exchange temperature control method, refer to Figures 31 - 36 and Figures 44 - 45 , in some embodiments, a chamber 15 is provided inside the disc 1, and the koji-making machine 10 includes a first heat exchange system 81. The first heat exchange system 81 is connected to the chamber 15 and introduces a heat exchange fluid into the chamber 15 to regulate the temperature of the material 20 by using the heat exchange between the heat exchange fluid and the material 20 on the disc 1.

[0128] In the above setting method, the disc 1 is no longer a solid disc but has a hollow sandwich layer, and a heat exchange fluid can be introduced into the sandwich layer by the first heat exchange system 81. The temperature of the material 20 is controlled by using the heat exchange between the heat exchange fluid and the material 20. The first heat exchange system 81 can be called a sandwich heat exchange system. The heat exchange fluid introduced into the sandwich layer can be a liquid such as water to better exchange heat with the material 20 and achieve a better temperature control effect.

[0129] It can be seen that based on the set first heat exchange system 81, an indirect heat exchange temperature regulation method based on the heat exchange between the heat exchange medium and the material 20 can also be realized, enriching the temperature regulation methods of the koji-making machine 10 and making the koji-making machine 10 no longer limited to the direct ventilation temperature regulation method.

[0130] In the above setting method, the chamber 15 can be located inside at least one of the disk body 11, the outer ring 13, and the inner ring 12 of the disk 1, so that the whole or part of the disk 1 becomes a sandwich structure. The parts of the chamber 15 located in the disk body 11, the outer ring 13, and the inner ring 12 can be respectively called the first chamber 151, the second chamber 152, and the third chamber (not shown in the figure) for easy distinction.

[0131] For example, referring to Figures 31 - 32 , in some embodiments, the chamber 15 includes a first chamber 151 provided inside the disk body 11. At this time, the disk body 11 is a sandwich structure. Since the material 20 is mainly stacked on the disk body 11, therefore, setting the disk body 11 as a sandwich structure and introducing a heat exchange fluid into the sandwich of the disk body 11 can meet most of the heat exchange requirements of the material 20 and achieve a good temperature regulation effect. Among them, referring to Figure 33 and Figure 34 , the inside of the first chamber 151 located in the disk body 11 can be divided into at least two heat exchange chambers 153. An inlet 157 and an outlet 158 are provided on the bottom wall of each heat exchange chamber 153, and the inlet 157 and the outlet 158 are respectively used for the heat exchange fluid to flow into and out of the first chamber 151. By setting different heat exchange chambers 153 inside the disk body 11, zonal heat exchange of the disk body 11 can be realized. Since each zone can exchange heat independently, the failure of a certain zone does not affect the heat exchange of other zones, with high reliability and convenient maintenance. This zonal heat exchange method of the disk body 11 is applicable to both the case where the disk 1 rotates (refer to Figures 33 - 36 ), and the case where the disk 1 does not rotate (refer to Figure 45 ). The heat exchange chambers 153 can be arranged in sequence along the circumferential direction of the disk 1, covering the entire circumference of the disk body 11, so as to realize the heat exchange of the material 20 on the entire circumference of the disk body 11.

[0132] For another example, returning to Figures 31 - 32 , in some embodiments, the chamber 15 includes a second chamber 152 provided inside the outer ring 13. At this time, 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 good temperature regulation effect.

[0133] For yet another example, continue to refer to Figures 31 - 32, in some embodiments, the chamber 15 includes both the first chamber 151 and the second chamber 152 simultaneously. At this time, both the disk body 11 and the outer ring 13 are sandwich structures. In this case, not only can the heat exchange fluid in the disk 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, enabling both the bottom and side portions of the material 20 to exchange heat with the heat exchange fluid. Therefore, it is beneficial to prevent temperature non-uniformity of the material 20 in the circumferential or height direction and achieve a more uniform temperature adjustment effect.

[0134] When the chamber 15 includes both the first chamber 151 and the second chamber 152 simultaneously, the second chamber 152 can communicate 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 disk 1. In this way, after the heat exchange fluid fully exchanges heat with the material 20 in the disk body 11, it then flows into the outer ring 13 to exchange heat with the material 20. This heat exchange method of first the disk body 11 and then the outer ring 13 is more in line with the characteristics that the material 20 has a larger laying area and a smaller thickness, and the heat exchange demand at the disk body 11 is greater, which is beneficial to achieving a better heat exchange effect. Moreover, this heat exchange method of first the disk body 11 and then the outer ring 13 is also more convenient for the layout of the first heat exchange system 81. At this time, the first heat exchange system 81 can be arranged below the disk body 11. Since there is a large space below the disk body 11, the arrangement is convenient, especially convenient for the layout of the first heat exchange system 81 when the disk 1 rotates.

[0135] When the disk 1 rotates, how to arrange the first heat exchange system 81 to avoid the entanglement of the pipeline during the rotation of the disk 1 is a difficult problem.

[0136] To solve the problem of the entanglement of the pipeline of the first heat exchange system 81 during the rotation of the disk 1, refer to Figures 31 - 32 , in some embodiments, when the disk 1 is rotatably arranged, the chamber 15 includes the first chamber 151 arranged inside the disk body 11, and the first heat exchange system 81 includes the first shell 811 and the second shell 812. The first shell 811 is arranged on the disk body 11 and rotates together with the disk 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 inlet ring groove 813 and an outlet ring groove 814 which are separated from each other. The second shell 812 is provided with an inlet 818 and an outlet 819 which are separated from each other. The inlet 818 communicates with the first chamber 151 through the inlet ring groove 813. The outlet 819 communicates with the first chamber 151 through the outlet ring groove 814. The inlet 818 is connected with an inlet pipe 81a and communicates with the heat exchange fluid supply source. The outlet 819 is connected with an outlet pipe 81b for discharging the heat exchange fluid.

[0137] Based on the above settings, the heat exchange fluid enters the first chamber 151 through the inlet 818 and the inlet annular groove 813, and after flowing through the disk 1, flows out to the outside through the discharge annular groove 814 and the discharge port 819. During the whole process, since the first housing 811 provided with the inlet annular groove 813 and the discharge annular groove 814 rotates together with the disk body 11, while the second housing 812 connected with the inlet pipe 81a and the discharge pipe 81b does not rotate together with the disk body 11, therefore, the flow of the heat exchange fluid is not affected by the rotation of the disk 1. No matter which angle the disk 1 rotates to, the inlet pipe 81a and the discharge pipe 81b can be in their original positions without rotating, and at the same time, the heat exchange fluid can enter and exit the first chamber 151 through the inlet annular groove 813 and the discharge annular groove 814, realizing interlayer heat exchange. It can be seen that the above setting method can meet the supply demand of the heat exchange fluid for the entire rotating disk 1 while effectively avoiding the entanglement of the inlet pipe 81a and the discharge pipe 81b.

[0138] Since the space below the disk body 11 is large and there is basically no obstruction, therefore, the first housing 811, the second housing 812, the inlet pipe 81a and the discharge pipe 81b can be conveniently arranged, so as to conveniently realize the arrangement and installation of the first heat exchange system 81.

[0139] Among them, referring to Figure 32 , in some embodiments, the inlet annular groove 813 is located radially inside the discharge annular groove 814. In this way, the layout is more compact and reasonable, which is convenient for the heat exchange fluid to flow radially inward first and then radially outward after entering the first chamber 151, and orderly realizes the temperature adjustment of the materials 20 at various parts of the entire disk body 11.

[0140] In order to guide the heat exchange fluid to flow orderly in the disk body 11, referring to Figures 31 - 36 , in some embodiments, a first partition 154 and a second partition 155 are provided in the first chamber 151. The first partition 154 extends along the radial direction of the disk 1 and has a gap with the inner ring 12. The second partition 155 is located on one side of the first partition 154 along the circumferential direction of the disk 1 and divides the space of the first chamber 151 on the side of the first partition 154 along the circumferential direction of the disk 1. An inlet 157 and an outlet 158 are provided on the bottom wall of the first chamber 151. The inlet 157 and the outlet 158 are respectively communicated with the inlet annular groove 813 and the discharge annular groove 814. The inlet 157 and the inlet annular groove 813 and the outlet 158 and the discharge annular groove 814 are located on opposite sides of the second partition 155 along the radial direction of the disk 1.

[0141] Based on the above settings, the heat exchange fluid entering the first chamber 151 can flow orderly through different positions along the radial direction of the disk body 11, and finally flow through the entire disk body 11 to fully exchange heat with the materials 20 on the disk body 11.

[0142] Here, taking the case where the inlet annular groove 813 is located radially inside the discharge annular groove 814 as an example, the flow process of the heat exchange fluid based on the above settings will be described.

[0143] Refer to Figures 31 - 36 , when the inlet annular groove 813 is located radially inside the discharge annular groove 814, the heat exchange fluid flowing into the inlet annular groove 813 can enter the first chamber 151 through the inlet 157. The heat exchange fluid entering the first chamber 151, due to being blocked by the first partition 154, can only first flow in the space on one side of the first partition 154 along the circumferential direction of the disk 1 in the first chamber 151 (the space on the side where the inlet 157 is located, marked as the first space 15a in Figure 34 ), and, due to being blocked by the second partition 155, the heat exchange fluid cannot flow radially outward of the disk 1, but can only flow radially inward of the disk 1. When flowing to a position close to the inner ring 12, it flows into the space on the other side of the first partition 154 along the circumferential direction of the disk 1 in the first chamber 151 through the gap between the inner ring 12 and the first partition 154 (the other space where the inlet 157 is not located, marked as the second space 15b in Figure 34 ), then turns back and flows radially outward of the disk 1, and finally flows to the outlet 158 and flows out of the disk body 11 through the outlet 158. The heat exchange fluid flowing out of the disk body 11, as Figure 32 shows, will flow through the discharge annular groove 814, the discharge port 819, and the discharge pipe 81b in sequence, and flow back to the heat exchange fluid supply source to realize the circulating flow of the heat exchange fluid.

[0144] In the case where the second chamber 152 is provided in the outer ring 13, the heat exchange fluid flowing from the radially inner side to the radially outer side of the disk body 11, when flowing near the outer ring 13, as Figures 33 - 34 shows, will first flow into the second chamber 152 through the inlet I of the second chamber 152, and after flowing through the second chamber 152, it will flow back into the first chamber 151 from the outlet O of the second chamber 152, and then will flow radially inward until it flows to the outlet 158 and flows out of the disk body 11 from the outlet 158. At this time, there is no gap between the first partition 154 and the outer ring 13, and the two are in contact with each other to prevent the fluid flowing to the outer ring 13 from flowing directly to the outlet 158 instead of flowing into the second chamber 152.

[0145] In the case where the second chamber 152 is not provided in the outer ring 13, the heat exchange fluid flowing from the radially inner side to the radially outer side of the disk body 11, when flowing near the outer ring 13, as Figures 35 - 36As shown, it no longer flows into the second chamber 152, but instead directly turns back through the gap between the first partition 154 and the outer ring 13, and changes to flow radially inwards until it reaches the outlet 158 and flows out of the outlet 158 to the outside of the disk body 11. That is to say, in this case, there is a gap between the first partition 154 and the outer ring 13.

[0146] It can be seen that when the inlet ring groove 813 is located radially inside the discharge ring groove 814, based on the provided first partition 154 and second partition 155, the heat exchange fluid can be guided to flow in the order of first radially inwards, then radially outwards, and then radially inwards again. This facilitates the heat exchange fluid to flow orderly through each radial part of the disk body 11 and exchange heat with the material 20 at various radial positions. Moreover, when there is a second chamber 152 inside the outer ring 13, it is also more convenient for the heat exchange fluid to flow from the first chamber 151 to the second chamber 152, facilitating the realization of the flow heat exchange process of the disk body 11 first and then the outer ring 13.

[0147] In the above embodiments, in order to improve the interlayer heat exchange effect, refer to Figures 31 - 32 , in some embodiments, there are baffles 156 arranged inside the chamber 15 to guide the heat exchange fluid flowing into the chamber 15 to flow in a baffled manner. Among them, as Figure 32 shown, multiple baffles 156 can be arranged side by side, and two adjacent baffles 156 can be arranged on the opposite side walls of the chamber 15 and partially staggered in the opposite direction of the two side walls to form a baffled flow channel to guide the heat exchange fluid to flow in a baffled manner in the chamber 15. For example, refer to Figure 32 , in some embodiments, multiple groups of baffles 156 can be arranged in the first chamber 151 inside the disk body 11. Each group of baffles 156 has multiple baffles 156 located at the same circumferential position. These baffles 156 at the same circumferential position are arranged side by side along the radius of the disk 1, and two adjacent baffles 156 are respectively connected to the upper and lower side walls of the first chamber 151 and are staggered in the up and down directions to form an S-shaped baffled flow channel. Since the baffled flow can extend the flow time of the heat exchange fluid in the chamber 15 and enable the heat exchange fluid to exchange heat with the material 20 more fully, it is beneficial to improve the temperature control effect on the material 20.

[0148] In addition, as another indirect heat exchange and temperature regulation method, refer to Figure 37, in some embodiments, the koji-making machine 10 includes a second heat exchange system 82. The second heat exchange system 82 includes a liquid storage tank 821. The liquid storage tank 821 is disposed below the disc 1 and is used to hold a liquid. At least a part of the disc 1 is immersed in the liquid in the liquid storage tank 821. In this way, an immersion heat exchange process can be achieved, and the temperature of the material 20 is adjusted by using the heat exchange between the liquid in the liquid storage tank 821 and the material 20 on the disc 1. This indirect heat exchange and temperature adjustment method is simple and easy to implement, and is applicable conveniently whether the disc 1 rotates or not.

[0149] Next, a further description will be given to Figures 1 - 45 each of the embodiments shown.

[0150] First, introduce Figures 1 - 34 the first embodiment shown.

[0151] Refer to Figures 1 - 2 , in this first embodiment, the koji-making machine 10 includes a disc 1, a discharging mechanism 2, a feeding mechanism 3, a material-turning mechanism 4, a temperature control device 5, a turntable mechanism 61, a ventilation device 7, a first heat exchange system 81, and a frame 91.

[0152] Among them, the disc 1 is rotatably disposed on the frame 91 and contains the material 20 that needs to be fermented and brewed inside. The discharging mechanism 2 is used to convey 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 convey the material 20 that needs to be fermented or brewed into the disc 1. The material-turning mechanism 4 is used to turn the material 20 on the disc 1. The temperature control device 5 is used to control the temperature and turn the material 20 on the disc 1. The turntable 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 temperature of the material 20 is controlled by using hot and cold air to penetrate the material 20. The first heat exchange system 81 is used to introduce a heat exchange fluid into the interlayer of the disc 1 to achieve indirect heat exchange and temperature control of the material 20.

[0153] Generally speaking, in the koji-making machine 10 of this embodiment, 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 20 is controlled by one or more of the material-turning mechanism 4, the temperature control device 5, the ventilation device 7, and the first heat exchange system 81. Finally, the fermented or brewed material 20 is conveyed to the next process by the discharging mechanism 2, which is the assembly of the device.

[0154] Next, each component will be introduced separately.

[0155] Figures 1 - 4 shows the structure of the disc 1 in this embodiment. As Figures 1 - 4As shown, in this embodiment, the disk 1 is an annular groove-shaped disk, which includes a disk body 11, an inner ring 12 and an outer ring 13. A discharge port 14 is provided at the center of the disk body 11. The outer ring 13 and the inner ring 12 are respectively arranged on the outer and inner circles of the disk body 11, and are inseparably connected to the disk body 11, so that the entire disk 1 becomes an integral structure. In this way, the disk 1 is in an annular groove shape, suitable for containing materials 20 in a liquid state, a liquid-solid mixed state or a solid state, so as to complete the fermentation and brewing process of the corresponding materials 20.

[0156] And, as Figure 3 shown, in this embodiment, an opening is provided on the inner ring 12, and a discharge door 16 is provided at the opening. The discharge door 16 is opened and closed under the drive of the door opening mechanism 62 to open or close the opening. The opening method of the discharge door 16 can be various. For example, it can be opened and closed by moving in the radial direction, or it can also be opened and closed by moving in the up and down direction. At the same time, the structure of the door opening mechanism 62 can be various. For example, the door opening mechanism 62 can include a driving cylinder (oil cylinder, electric cylinder or air cylinder) or a linear motor.

[0157] Figures 1 - 2 And Figures 3 - 4 shows the structure of the discharge mechanism 2 in this embodiment. Refer to Figures 1 - 2 And Figures 3 - 4 , in this embodiment, the discharge mechanism 2 includes a first baffle 26 and a second baffle 27, and is lifted under the drive of the discharge lifting mechanism 22.

[0158] Among them, as Figure 1 and Figure 4 shown, both the first baffle 26 and the second baffle 27 extend along the radial direction of the disk 1, and the lengths of both are equal to the radial distance from the outer ring 13 to the inner ring 12, so that both the first baffle 26 and the second baffle 27 cover the entire radius range of the disk 1.

[0159] At the same time, as Figure 1 and Figure 4 shown, in the circumferential direction of the disk 1, the first baffle 26 is located on one side of the discharge door 16, and the second baffle 27 is located on one side of the first baffle 26.

[0160] And, the first baffle 26 does not rotate relative to the disk 1, so that during the rotation of the disk 1, the first baffle 26 can rotate with the disk 1, and thus always be located on one side of the discharge door 16 along the circumferential direction of the disk 1. At the same time, the second baffle 27 rotates relative to the disk 1, so that during the rotation of the disk 1, the second baffle 27 does not rotate with the disk 1.

[0161] Based on the above settings, refer to Figure 4, when the disc 1 performs operations such as brewing or fermentation, the discharging mechanism 2 moves upward, and neither the first baffle 26 nor the second baffle 27 contacts the material 20; while when the disc 1 performs the discharging operation, the discharging mechanism 2 descends under the action of the discharging lifting mechanism 22 and lands on the disc body 11, so that the bottom edges of the first baffle 26 and the second baffle 27 closely adhere to the upper surface of the disc body 11 and are in full contact with the material 20. In this case, when the disc 1 rotates, the second baffle 27 can push the material 20 towards the first baffle 26 in the direction opposite to the rotation direction of the disc 1, squeezing the material 20 towards the opening opened by the discharging door 16 on the inner ring 12, so that the material 20 falls into the discharging port 14 from the opening and is discharged from the discharging port 14, completing the central discharging process.

[0162] Due to the rotation of the disc 1, the opening on the inner ring 12 will change its circumferential position as the disc 1 rotates. Therefore, at this time, as Figures 2 - 3 shown, the discharging port 14 can be designed to be annular, so that when the opening on the inner ring 12 rotates to different positions, the material 20 can fall from the opening into the discharging port 14 for discharging.

[0163] The material 20 falling from the discharging port 14 can be caught by a receiving device such as a receiving tray, and then transported to a designated position in the downstream process by a transporting device. In this case, since the discharging port 14 is at the center of the disc 1 and the corresponding radial range is small, the diameter of the receiving tray can be small and does not need to occupy a large space.

[0164] However, in order to further facilitate the transfer of the material to the downstream process, see Figure 2 , in this embodiment, no receiving device such as a receiving tray is provided below the discharging port 14, but a discharging mechanism 63 is provided. The discharging mechanism 63 is arranged below the discharging port 14, communicated with the discharging port 14, and conveys the material 20 towards the radial outside of the disc 1. In this way, the material 20 falling from the discharging port 14 can directly fall onto the discharging mechanism 63 and be conveyed towards the radial outside of the disc 1 by the discharging mechanism 63. In this way, since there is no need to set up a receiving tray, the ground space occupied by the receiving tray can be saved, and 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 discharging mechanism 63, the material transportation is more convenient, the connection between processes is closer, and it is beneficial to improve the overall production efficiency.

[0165] As Figure 4 shown, in this embodiment, the material 20 moves towards the opening corresponding to the discharging door 16 only under the relative rotation of the first baffle 26 and the second baffle 27. However, as a variant, as Figures 6 - 7As shown, a conveyor 21 can also be added between the first baffle 26 and the second baffle 27. The conveyor 21 further drives the material 20 to move towards the opening corresponding to the discharge door 16, so as to improve the discharge efficiency and the cleanliness of the discharge. Specifically, the conveyor 21 can be a screw conveyor 23 or a scraper conveyor. It is arranged above the disc body 11 and extends along the radial direction of the disc 1, from the outer ring 13 to the inner ring 12.

[0166] In addition, as Figure 2 shown, in this embodiment, a spraying device 25 is further provided on the discharge mechanism 2. The spraying device 25 includes a liquid spraying pipe 251. The liquid spraying pipe 251 sprays liquids such as water towards the material 20 and the conveyor 21, so as to add liquid to the material 20 or clean the conveyor 21, making the material 20 easier to ferment and brew or be transported, or making the conveyor 21 cleaner. Among them, a plurality of nozzles can be provided on the liquid spraying pipe 251 to further improve the spraying effect.

[0167] Figures 8 - 9 shows the structure of the feeding mechanism 3 in this embodiment. As Figures 8 - 9 shown, in this embodiment, the feeding mechanism 3 is arranged above the disc body 11 and does not rotate with the disc 1. It includes a first conveying device 31 and a second conveying device 32. Among them, both the first conveying device 31 and the second conveying device 32 are arranged on a feeding frame 33 connected to the frame 91 and both extend along the radial direction of the disc 1. The first conveying device 31 is arranged immovably along the radial direction of the disc 1, and a feeding port 34 is provided on the first conveying device 31. The second conveying device 32 is arranged below the first conveying device 31 and is arranged movably along the radial direction of the disc 1, and a cloth feeding port 35 is provided thereon. Specifically, as Figure 9 shown, rollers 39 are provided below the second conveying device 32. The rollers 39 are in contact with the feeding frame 33. By rotating the rollers 39, the second conveying device 32 can be moved along the radial direction of the disc 1 on the feeding frame 33. In this way, the second conveying device 32 can move relative to the first conveying device 31 along the radial direction of the disc 1, so that the whole feeding mechanism 3 can be telescopic and can transport the material 20 to different positions of the disc 1.

[0168] When feeding is required, the material 20 drops from the upper-level conveying device into the feeding port 34 and then onto the first conveying device 31. After that, it drops from the first conveying device 31 onto the second conveying device 32 and falls from the feeding port 35 of the second conveying device 32 onto the disk 1. Since the second conveying device 32 can move radially relative to the disk 1, the second conveying device 32 can convey the material 20 to different radial positions of the disk 1. And since the disk 1 rotates relative to the feeding mechanism 3, the feeding mechanism 3 can send the material 20 to different circumferential positions of the disk 1. Furthermore, with the cooperation of the feeding mechanism 3 and the disk 1, the material 20 can be evenly placed on the entire disk 1.

[0169] Among them, as Figure 9 shown, in this embodiment, the first conveying device 31 and the second conveying device 32 are specifically belt conveying devices 36. However, it can be understood that as a variant, as Figure 10 and Figure 11 shown, the first conveying device 31 and the second conveying device 32 can also be screw conveying devices 37 or scraper conveying devices 38.

[0170] Figures 12 - 13 shows the structure of the material turning mechanism 4 in this embodiment. As Figures 12 - 13 shown, in this embodiment, the material turning mechanism 4 is located above the disk body 11, does not rotate with the disk 1, and 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 so that the material 20 can evenly reach the required temperature, humidity, and strain environment. The material turning lifting mechanism 42 is arranged on the frame 91 and is drivingly connected to the material turning device 41 to drive the material turning device 41 to lift and control 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 to achieve the material turning function. After the material turning device 41 rises above the material 20, it no longer contacts the material 20 and cannot turn the material 20 anymore.

[0171] During the production process, when the material turning lifting mechanism 42 lifts the material turning device 41 to the highest point, the material turning device 41 stops turning. And when the material turning lifting mechanism 42 drives the material turning device 41 to lift and lower at other heights below the highest point, the material turning device 41 can turn the material 20 at different heights.

[0172] Among them, as Figure 12 shown, in this embodiment, the material turning device 41 is specifically a horizontal turning and throwing type material turning device 43, and its own rotation axis is along the horizontal direction. However, the structure of the material turning device 41 is not limited to this. For example, as a variant, as Figures 14 - 15As shown, the material turning device 41 can also be a vertical spiral material turning device 44, which includes a plurality of spiral material turning members whose own rotation axes extend in the vertical direction. For another example, although not shown, the material turning device 41 can also be a rake-type material turning device. Or, according to the material characteristics or process requirements, the material turning device 41 can adopt a combination of two or more of the horizontal throwing material turning device 43, the vertical spiral material turning device 44 or the rake-type material turning device.

[0173] Figure 16 The structure of the temperature regulating device 5 in this embodiment is shown. Refer to Figure 16 , in this embodiment, the temperature regulating device 5 is arranged on the frame 91, does not rotate with the disc 1, and includes a bracket 57 and a heat exchanger 51. The bracket 57 is fixedly connected to the frame 91. The heat exchanger 51 is arranged on the bracket 57 and includes a main pipe 52 and branch pipes 53. A heat exchange medium inlet 54 and a heat exchange medium outlet 55 are provided on the main pipe 52 for the heat exchange medium to enter and exit the heat exchanger 51 respectively. A plurality of branch pipes 53 are communicated with the main pipe 52 side by side along the radial direction of the disc 1 and extend downward from the main pipe 52 to contact the material 20. Since the heat exchange medium is introduced into the heat exchanger 51, 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 to realize the regulation of the temperature of the material 20. And, since the disc 1 rotates and the heat exchanger 51 does not rotate therewith, there is relative rotation between the two, so the heat exchanger 51 can also play a role in turning the material at the same time. It can be seen that the heat exchanger 51 in this embodiment can not only control the temperature but also turn the material, and can be used for two purposes with one machine.

[0174] Figures 17 - 18 The structure of the heat exchanger 51 is further shown. As Figures 17 - 18 shown, in this embodiment, the branch pipe 53 of the heat exchanger 51 is generally columnar, hollow inside, and has the same cross-sectional size from top to bottom. Of course, the shape of the branch pipe 53 can also have other variations. For example, from Figures 19 - 20 it can be seen that in some embodiments, the branch pipe 53 is generally U-shaped, hollow inside, and has the same cross-sectional size from top to bottom. For another example, from Figures 21 - 22 it can be seen that in some other embodiments, the branch pipe 53 is generally rake-shaped, hollow inside, and the cross-sectional size gradually becomes larger from top to bottom. For another example, as Figures 23 - 24 shown, in some other embodiments, the branch pipe 53 is generally plow-shaped, hollow inside, has the same 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.

[0175] Figures 25 - 26 The structure of the turntable mechanism 61 in this embodiment is shown. Refer to Figures 25 - 26, in this embodiment, the disc 1 is rotatably arranged on the frame 91 and is driven to rotate by the turntable mechanism 61. Specifically, the middle part of the disc 1 is supported by a central bearing 614 (such as a centering rolling bearing), and the outer edge is supported by a first supporting wheel 613. In this way, the disc 1 can rotate relative to the frame 91 around the longitudinal rotation axis located at the center of the disc 1. The turntable mechanism 61 includes a turntable driving mechanism 611 and a first transmission mechanism 612. The turntable driving mechanism 611 is drivingly connected to the disc 1 through the first transmission mechanism 612 for driving the disc 1 to rotate. The turntable driving mechanism 611 is arranged on the outer edge of the disc 1 and includes one, two or more motors. The first transmission mechanism 612 is arranged on the outer edge of the disc 1 and includes gears and teeth or pins located around the entire circumference of the disc 1. The teeth or pins are drivingly connected to the turntable driving mechanism 611 through the gears, so that when the turntable driving mechanism 611 is started, the disc 1 can be driven to rotate automatically around the longitudinal rotation axis as a whole. In this way, when the turntable driving mechanism 611 is started, the disc 1 can be driven to rotate automatically around the longitudinal rotation axis as a whole.

[0176] Since the disc 1 can rotate around the longitudinal rotation axis under the action of the turntable mechanism 61, while the second baffle 27, the feeding mechanism 3, the material turning mechanism 4 and the temperature regulating device 5 do not rotate around the longitudinal rotation axis, therefore, the relative rotation around the longitudinal rotation axis between the second baffle 27, the feeding mechanism 3, the material turning mechanism 4 and the temperature regulating device 5 and the disc 1 can be realized, so that as the disc 1 rotates, the second baffle 27, the feeding mechanism 3, the material turning mechanism 4 and the temperature regulating device 5 can reach different circumferential positions of the disc 1, and discharging, feeding, material turning and temperature regulation are carried out at different circumferential positions, and finally discharging, feeding, material turning and temperature regulation for the whole circumference of the disc 1 are realized.

[0177] The rotation of the disc 1 not only facilitates the realization of discharging, feeding and material turning for the whole circumference, but also is beneficial to the uniform fermentation of the material 20. And if the material 20 needs to be static during the fermentation process, the disc 1 can remain stationary and not rotate during the whole fermentation process or a certain period of time during the fermentation process.

[0178] Figures 27 - 28 shows the structure of the ventilation device 7 in this embodiment. Refer to Figures 27 - 28 , 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 to make cold and hot air 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 communicated with the inside and outside through the air duct 72 to drive air into the koji-making chamber 78. A regulating valve 74 and a heat exchanger 73 are arranged in the air duct 72. The regulating valve 74 adjusts the air volume. The heat exchanger 73 adjusts the temperature of the air flowing into the room.

[0179] As a Figures 27 - 28In a variant of the ventilation device 7 shown, a heat exchanger 73 may not be provided in the air duct 72, and 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 interior. Additionally, as Figures 29 - 30 shown, when the koji-making chamber 78 is a non-enclosed space and the koji-making chamber 78 communicates with the outside through the window 75, the ventilation device 7 may only include the 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.

[0180] Figures 31 - 34 The structure of the first heat exchange system 81 and the disc 1 supporting the first heat exchange system 81 in this embodiment is shown. As Figures 31 - 34 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, such that both the disc body 11 and the outer ring 13 become sandwich structures. The first heat exchange system 81 is disposed below the disc body 11 and is used to introduce a heat exchange fluid into the first chamber 151 and the second chamber 152, so as to utilize the heat exchange between the heat exchange fluid and the material 20 to adjust the temperature of the material 20.

[0181] Among them, as Figures 31 - 34 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 disc body 11, such that the first shell 811 can rotate together with the disc 1. The second shell 812 is disposed below the first shell 811, and a bearing 816 is provided between the second shell 812 and the first shell 811. The outer ring of the bearing 816 is engaged with the second shell 812, and the inner ring of the bearing 816 is engaged with the first shell 811, such that the second shell 812 can remain stationary when the first shell 811 and the disc 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 and prevent the heat exchange fluid from leaking. 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 chamber 151 inside the disc body 11 through the second shell 812 and the first shell 811. Control valves 817 are provided on both the inlet pipe 81a and the outlet pipe 81b to adjust the flow rate of the heat exchange fluid. Although not shown, it is not difficult to understand that a pump may be provided on the inlet pipe 81a and / or the outlet pipe 81b to drive the heat exchange fluid to flow.

[0182] Specifically, as Figure 32As shown, in this embodiment, an inlet 818 and an outlet 819 which are separated from each other are provided on the second housing 812. The inlet pipe 81a and the outlet pipe 81b are respectively connected to the inlet 818 and the outlet 819. In the radial direction of the disc 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. At the same time, as Figure 32 shown, an inlet annular groove 813 and an outlet annular groove 814 which are separated from each other are provided on the first housing 811. Both the inlet annular groove 813 and the outlet annular groove 814 are circular annular grooves, and the two are arranged in sequence along the direction from the inner ring 12 to the outer ring 13, and are respectively communicated with the inlet pipe 81a and the outlet pipe 81b through the inlet 818 and the outlet 819, and are both communicated with the first chamber 511 inside the disc body 11. In this way, the heat exchange fluid flowing from the inlet pipe 81a to the disc 1 can flow into the disc body 11 through the inlet 818 and the inlet annular groove 813 in sequence, and the heat exchange fluid flowing through the disc body 11 and the outer ring 13 can flow out through the outlet annular groove 814, the outlet 819 and the outlet pipe 81b in sequence.

[0183] Since the second housing 812 to which the inlet pipe 81a and the outlet pipe 81b are connected does not rotate with the disc 1, during the rotation of the disc 1, the inlet pipe 81a and the outlet pipe 81b can not rotate. Therefore, the inlet pipe 81a and the outlet pipe 81b will not be entangled due to rotating with the disc 1.

[0184] Moreover, since the inlet annular groove 813 and the outlet annular groove 814 are arranged along the entire circumference of the disc 1 and are always communicated with the disc 1, the flow of the heat exchange fluid is not affected by the rotation of the disc 1. No matter which angle the disc 1 rotates to, the heat exchange fluid can enter and exit the disc body 11 through the inlet annular groove 813 and the outlet annular groove 814 to exchange heat with the material 20.

[0185] Among them, in order to enable the inlet annular groove 813 and the outlet annular groove 814 to always be communicated with the disc 1 during the rotation of the disc 1, in combination with Figures 31 - 34 it can be seen that in this embodiment, a plurality of groups of inlets 157 and outlets 158 are provided on the bottom wall of the disc body 11. These plurality of groups of inlets 157 and outlets 158 are arranged at intervals along the circumferential direction of the disc body 11 on the entire circumference of the disc body 11, and the inlets 157 and the outlets 158 in each group of inlets 157 and outlets 158 are respectively communicated with 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 communicated with the disc 1 during the rotation of the disc 1.

[0186] Specifically, as Figures 32 - 34As shown, in this embodiment, the first chamber 151 inside the disk body 11 is partitioned into a plurality of heat exchange chambers 153. These plurality of heat exchange chambers 153 are distributed along the entire circumference of the disk body 11, and a set of inlets 157 and outlets 158 are provided on the bottom wall of each heat exchange chamber 153, so that each heat exchange chamber 153 communicates with the inlet ring groove 813 and the discharge ring groove 814. And, from Figures 32 - 34 it can be seen that in this embodiment, a first partition 154 and a second partition 155 are provided in each heat exchange chamber 153. Among them, the first partition 154 extends along the radial direction of the disk 1, and divides the inside of the heat exchange chamber 153 into a first space 15a and a second space 15b located on both sides of the first partition 154 along the circumferential direction of the disk 1. The inlets 157 and outlets 158 are located in the first space 15a. The second partition 155 is arranged in the first space 15a and is located between the inlets 157 and outlets 158 along the radial direction of the disk 1 to partition the inlets 157 and outlets 158, preventing the heat exchange fluid flowing into the heat exchange chamber 153 from the inlets 157 from flowing out directly from the outlets 158 without flowing through the disk body 11. And, as Figure 34 shown, in this embodiment, there is no gap between the first partition 154 and the outer ring 13, but there is a gap between the first partition 154 and the inner ring 12, so that the first space 15a and the second space 15b communicate on the side close to the inner ring 12, but are isolated and not connected on the side close to the outer ring 13. At the same time, as Figure 34 shown, in this embodiment, the radially outer end of the first space 15a communicates with the outlet O of the second chamber 152 located inside the outer ring 13, and the radially outer end of the second space 15b communicates with the inlet I of the second chamber 152. And, a plurality of baffle plates 156 are provided in both the first space 15a and the second space 15b, so that a baffle flow path is formed in both the first space 15a and the second space 15b, and the heat exchange fluid flows tortuously in both the first space 15a and the second space 15b.

[0187] Based on the above settings, during the rotation of the disc 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 through the inlet 157 of each heat exchange chamber 153. And the heat exchange fluid entering each heat exchange chamber 153 first enters the first space 15a. In the first space 15a, due to the blockage of the second partition 155, the heat exchange fluid cannot flow radially outward towards the outlet 158, but can only first flow radially inward towards the disc 1. And when it flows to 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, and makes a U-turn in the second space 15b and changes to flow radially outward towards the disc 1. When the heat exchange fluid flows radially outward towards the disc 1 to the outer end of the first partition 154 in the second space 15b, since there is no gap between the first partition 154 and the outer ring 13, therefore, the heat exchange fluid will not directly flow back into the first space 15a, but will flow into the second chamber 152 through the inlet I of the second chamber 152, and after flowing through the second chamber 152, it flows back into the first space 15a from the outlet O of the second chamber 152, then flows towards the outlet 158, flows out from the outlet 158 into the discharge annular groove 814, and finally flows into the discharge pipe 81b.

[0188] It can be seen that based on the above setting method, the heat exchange fluid can first flow through the disc body 11, and then flow through the outer ring 13. And when flowing through the disc body 11, it can first flow radially inward and then radially outward. The whole flow process is orderly and controllable, and the materials 20 at different radial positions and different height positions on the disc 1 can be orderly temperature-controlled, which is beneficial to making the materials 20 on the whole disc 1 reach the temperature that can better meet the process requirements.

[0189] Figures 35 - 36 Shows the flow path inside the disc body 11 when the second chamber 152 is not provided in the outer ring 13. As Figures 35 - 36 shown, when the second chamber 152 is not provided in the outer ring 13, multiple heat exchange chambers 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 chamber 153 to divide the heat exchange chamber 153 into the first space 15a and the second space 15b. The main difference is that the first space 15a and the second space 15b are no longer connected to the inside of the outer ring 13 at one end close to the outer ring 13, but are separated from the outer ring 13, and 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 on the side of the outlet 158, so that the heat exchange fluid flowing into the second space 15b no longer flows into the outer ring 13, but directly flows 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 between the heat exchange fluid and the material 20 is carried out at the outer ring 13, and the heat exchange fluid only makes a U-turn flow in the disc body 11 and exchanges heat with the material 20.

[0190] As Figures 31 - 36 an alternative to the first heat exchange system 81 shown, as Figure 37 shown, the koji-making machine 10 may include a second heat exchange system 82, which includes a liquid storage tank 821, a liquid level gauge 822, a liquid inlet valve 823, and a liquid outlet valve 824. The liquid storage tank 821 is disposed below the disc 1, and contains a liquid such as water inside. At least a part of the disc 1 is immersed in the liquid in the liquid storage tank 821, so that the liquid in the liquid storage tank 821 can exchange heat with the material 20 on the disc 1, changing the temperature of the material 20 and realizing the immersion temperature adjustment process. The liquid level gauge 822 is disposed on the liquid storage tank 821 for detecting the liquid level in the liquid storage tank 821 to prevent the liquid from being too much or too little. The liquid inlet valve 823 and the liquid outlet valve 824 are respectively disposed on the liquid inlet pipeline and the liquid outlet pipeline of the liquid storage tank 821 to control whether to inject liquid into the liquid storage tank 821 or whether to discharge the liquid in the liquid storage tank 821.

[0191] Next, the second embodiment shown will be introduced. Figures 38 - 45 as shown.

[0192] As Figures 38 - 45 shown, in this second embodiment, the koji-making machine 10 still includes a disc 1, a discharging mechanism 2, a feeding mechanism 3, a material turning mechanism 4, a temperature adjusting device 5, a ventilation device 7, a first heat exchange system 81, and a frame 91, but no longer includes a turntable mechanism 61, but includes a rotating frame 92 and a rotating frame mechanism 93. Because an important difference between this embodiment and the first embodiment shown above is that the disc 1 no longer rotates, but instead the second baffle 27, the feeding mechanism 3, the material turning mechanism 4, and the temperature adjusting device 5 rotate. Figures 1 - 37

[0193] Next, the differences between this second embodiment and the foregoing first embodiment will be mainly introduced. For other un-described parts, reference may be made to the description of the foregoing first embodiment for understanding.

[0194] Figures 38 - 43 As Figures 38 - 43 shown, in this second embodiment, although the disc 1 is still in a ring groove shape, it is no longer rotatably disposed on the frame 91, but is non-rotatably disposed on the frame 91. In this case, in order to realize the relative rotation between the second baffle 27, the feeding mechanism 3, the material turning mechanism 4, and the temperature adjusting device 5 and the disc 1, as Figures 38 - 43 shown, the koji-making machine 10 includes a rotating frame 92, the rotating frame 92 is rotatably disposed, and the second baffle 27, the feeding mechanism 3, the material turning mechanism 4, and the temperature adjusting device 5 are all disposed on the rotating frame 92. At the same time, the koji-making machine 10 includes a rotating frame mechanism 93, and the rotating frame mechanism 93 is drivingly connected to the rotating frame 92 to drive the rotating frame 92 to rotate, and further drive the second baffle 27, the feeding mechanism 3, the material turning mechanism 4, and the temperature adjusting device 5 to rotate.

[0195] Specifically, as Figures 38 - 43 shown, in this embodiment, the middle part 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 supporting wheel 933 to achieve the rotatable setting of the rotating frame 92. The rotating frame mechanism 93 includes a frame driving mechanism 931 and a second transmission mechanism 932. The frame driving mechanism 931 is drivingly connected to the rotating frame 92 through the second transmission mechanism 932 for driving the rotating frame 92 to rotate. Among them, a track 935 is provided below the second supporting wheel 933 to guide the rotation of the rotating frame 92. The track 935 can be fixed to the frame 91. In addition, the frame driving mechanism 931 is arranged on the outer edge of the rotating frame 92 and includes one, two or more motors. The second transmission mechanism 932 is arranged on the outer edge of the disc 1 and is a pin-and-tooth transmission mechanism.

[0196] Based on the above settings, when the frame driving mechanism 931 is started, it can drive the rotating frame 92 to rotate around the longitudinal rotation axis located at the center of the disc 1, so that the second baffle 27, the feeding mechanism 3, the material turning mechanism 4 and the temperature adjusting device 5 located on the rotating frame 92 can rotate together with the rotating frame 92, thereby realizing the relative rotation between the second baffle 27, the feeding mechanism 3, the material turning mechanism 4, the temperature adjusting device 5 and the disc 1.

[0197] By setting the rotating frame 92, it is more simple and convenient to realize the relative rotation between the second baffle 27, the feeding mechanism 3, the material turning mechanism 4, the temperature adjusting device 5 and the disc 1.

[0198] In this embodiment, the disc 1 does not rotate and the second baffle 27 rotates. Therefore, the working process of the discharging mechanism 2 can be roughly as follows:

[0199] When the disc 1 performs operations such as brewing or fermentation, the discharging mechanism 2 moves upward, and neither the first baffle 26 nor the second baffle 27 contacts the material 20; when the disc 1 performs the discharging operation, the discharging mechanism 2 descends onto the disc body 11, and the first baffle 26 and the second baffle 27 contact the material 20. In this case, the rotating frame 92 rotates and the second baffle 27 rotates, which can push the material 20 to the radius range corresponding to the discharging door 16 and, together with the first baffle 26, squeeze the material 20 out of the opening opened by the discharging door 16 to complete the discharging operation.

[0200] Since the disc 1 of this embodiment does not rotate, the discharging door 16 can be arranged on the inner ring 12 or the outer ring 13, and the discharging process can be conveniently carried out. Figures 39 - 40 shows the case where the discharging door 16 is arranged on the inner ring 12. At this time, a discharging port 14 can be arranged on the disc body 11. And since the disc 1 does not rotate and the discharging point is fixed in the circumferential direction, the discharging port 14 can be Figure 39 shown in a ring shape as Figure 40As shown, it is non-circular. Figure 41 The figure shows a situation where the discharge gate 16 is arranged on the outer ring 13 . At this time, a discharge chute 17 can be arranged on the outer side of the outer ring 13 below the discharge gate 16 to further guide the material 20 to fall.

[0201] In addition, since the disk 1 does not rotate, it will not cause the problem of pipeline winding, so the structure of the first heat exchange system 81 can be simpler. Figure 44 As shown, in the second embodiment, only the disc body 11 of the disc 1 adopts a sandwich structure, and a first cavity 151 is provided inside, and no sandwich is provided inside the inner ring 12 and the outer ring 13, and the first heat exchange system 81 no longer includes a first shell 811 and a second shell 812 that can rotate relatively, but 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 have the problem of rotation and entanglement, which is simple and convenient.

[0202] Figure 45 FIG. 2 shows a schematic diagram of the flow path on the disk 11 in this embodiment. Figure 45 As shown, in this embodiment, the first chamber 151 in the disc body 11 is still divided into a plurality of heat exchange chambers 153, which are arranged along the circumference of the disc 1 and cover the entire circumference of the disc body 11. In addition, an inlet 157 and an outlet 158 ​​are provided on the bottom wall of each heat exchange chamber 153, and the inlet 157 and the outlet 158 ​​are connected to the inlet pipe 81a and the outlet 81b respectively. At the same time, a plurality of baffles 156 are provided in each heat exchange chamber 153 to form a baffle channel. In this way, the heat exchange fluid in the inlet pipe 81a can enter the heat exchange chamber 153 from the inlet 157, and after multiple turns in each heat exchange chamber 153, it flows out from the outlet 158 ​​and flows into the outlet pipe 81b, thereby finally achieving temperature regulation of the material 20 on the entire disc body 11.

[0203] In summary, the koji making machine 10 provided in the embodiment of the present disclosure can conveniently realize the discharge of the annular groove disc, and can more effectively control the material temperature to achieve a better fermentation and brewing effect.

[0204] The above description is only an exemplary embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
