[0090] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to 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 following description of 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 labor fall within the scope of protection of the present disclosure.

[0091] The technologies, methods and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but in appropriate cases, the technologies, methods and devices should be considered as part of the specification.

[0092] In the description of the present disclosure, it should be understood that the use of the words "first", "second", etc. to qualify parts is merely for the convenience of distinguishing the corresponding parts, 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.

[0093] 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" indicate the orientation or positional relationship, which is generally based on the orientation or positional relationship when the mashing machine is normally placed, wherein the direction opposite to the gravity is downward, and the direction opposite to the gravity is downward; the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component. In addition, unless otherwise stated, the orientation words "circumferential" and "radial" generally refer to the circumferential and radial of the disc.

[0094] 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.

[0095] Figures 1-46 The structure of the mashing machine of the present disclosure is exemplarily shown. In order to clearly show the structure, some structures are simplified or omitted in some drawings.

[0096] Referring to Figures 1-2 , the mashing machine 10 comprises a disc 1, a discharging mechanism 2, a feeding mechanism 3, a stirring mechanism 4 and a frame 91.

[0097] 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 the designated position of 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, so that the fermentation is 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 turning mechanism 4 are arranged above the disc 1 and relatively rotatable with the disc 1, so that the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the turning mechanism 4 and the disc 1 can realize the discharging, feeding and turning of the disc 1 in the whole circumferential direction. In order to realize the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the turning mechanism 4 and the disc 1, the disc 1 can rotate while the discharging mechanism 2, the feeding mechanism 3 and the turning mechanism 4 do not rotate, or the discharging mechanism 2, the feeding mechanism 3 and the turning mechanism 4 can rotate while the disc 1 does not rotate. Here, the rotation of the disc 1, the discharging mechanism 2, the feeding mechanism 3 and the turning 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 called longitudinal rotation axis in the following.

[0099] Wherein, referring to Figures 2-4 In the embodiment 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 extended upward by the disc body 11 to form the inner and outer walls 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 which is not in the shape of a ring groove in the related art, the disc 1 in the shape of a ring groove has a wider application range, because the disc 1 in the shape of a ring groove can be used not only for the fermentation of solid materials but also for the fermentation of liquid or mixed solid-liquid materials, thereby providing a device basis for the fermentation of materials containing liquid. When the disc 1 is in the shape of a ring 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, especially 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 containing liquid, can be more conveniently realized.

[0101] However, the ring groove-shaped disc 1 has a problem of difficult discharging. The disc 1 not in a ring groove shape can be conveniently discharged from the radial side of the disc 1. For example, for the disc 1 not including the outer ring 13, a discharging mode (which can be referred to as an outer ring discharging mode) of discharging from the radial outer side is usually adopted, that is, the discharging mechanism 2 transports the material 20 to the radial outer side of the disc 1 after the material is fermented, and discharges the material from the radial outer side 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 from the outer edge of the disc body 11 under the action of the discharging mechanism 2, and the outer ring discharging is realized. However, for the disc 1 in a ring groove shape, 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 it is difficult to directly discharge the material from the radial side of the disc body 11 by using the discharging mechanism 2. For example, it is difficult to directly discharge from the radial outer side due to the blocking of the outer ring 13. For another example, it is also difficult to directly discharge from the radial inner side due to the blocking of the inner ring 12.

[0102] It can be seen that the discharging problem is an important problem restricting the development of the ring groove-shaped disc starter machine, and needs to be solved urgently.

[0103] In view of the above situation, referring to Figures 2-4 In the embodiment of the present disclosure, the center of the disc body 11 is provided with a discharging port 14, and the inner ring 12 is no longer an integral structure with the disc body 11, but a split structure, and the two are separably combined. Meanwhile, the starter machine 10 includes an inner ring driving mechanism 62, which is drivingly connected with the inner ring 12 and drives the inner ring 12 to move, so as to control the separation or combination of the inner ring 12 and the disc body 11.

[0104] Since the inner ring 12 can be separated or combined with the disc body 11 under the driving of the inner ring driving mechanism 62, when the inner ring 12 is separated from the disc body 11, the inner ring 12 can no longer block the flow of the material 10 on the disc 1 to the discharging port 12 located at the center of the disc body 11, so that the material 20 can flow to the discharging port 12 for discharging.

[0105] It can be seen that by setting the inner ring 12 to be separable from the disc body 11 and controlling the separation of the inner ring 12 from the disc body 11, the discharging difficulty of the ring groove-shaped disc 1 can be ingeniously solved, and the starter machine 10 can be conveniently discharged.

[0106] Moreover, when discharging is not needed, the inner ring 12 can still be combined with the disc body 11 to block the material 20, so as to prevent the material 20 from falling or leaking, so that the inner ring 12 and the inner ring driving mechanism 62 are set to meet the requirements of preventing the material from leaking and falling before fermentation is completed, and also meet the requirement of discharging after fermentation is completed.

[0107] It can be seen that by controlling the separation or combination of the inner ring 12 and the disc body 11, the disc 1 can meet the requirements of preventing leakage and falling of the material before the fermentation is completed, and can also meet the requirements of discharging the material after the fermentation is completed, thereby ingeniously solving the discharging problem of the ring groove-shaped disc 1, and enabling the ring groove-shaped disc 1 to be conveniently discharged.

[0108] In addition, the discharging mode of controlling the separation of the inner ring 12 and the disc body 11 has no special requirements for the rotation of the disc 1, and can be applied to the case where the disc 1 rotates or does not rotate, thereby having a wide application range.

[0109] In addition, the discharging mode of controlling the separation of the inner ring 12 and the disc body 11 can also enable the discharging process to be smoothly completed without improving the structure of the discharging mechanism 2, and even enables the discharging mechanism 2 to be omitted, especially for some materials 20 in a good flow state after fermentation, the discharging mechanism 2 can be omitted. Because when the inner ring 12 is separated from the disc body 11, the material 20 in a good flow state can flow to the discharge port 14 by itself without the need for the discharging mechanism 2 to transport, therefore, in this case, the discharging mechanism 2 can be omitted to realize the discharging process, thereby simplifying the overall structure of the koji making machine 10.

[0110] Exemplarily, referring to Figures 2-4 In some embodiments, the inner ring driving mechanism 62 includes a lifting driving mechanism 621, which is drivingly connected with the inner ring 12 and controls the separation or combination of the inner ring 12 and the disc body 11 by driving the inner ring 12 to lift. In this case, the inner ring driving mechanism 62 can control the separation or combination of the inner ring 12 and the disc body 11 by driving the inner ring 12 to lift, thereby controlling whether to discharge.

[0111] As shown in Figure 2 , under the driving of the lifting driving mechanism 621, the inner ring 12 can move between a lower limit position and an upper limit position. Wherein, the state of the inner ring 12 in the lower limit position is as shown in the solid line part of Figure 3 and Figure 2 ; and the state of the inner ring 12 in the upper limit position is as shown in the dotted line part of Figure 4 and Figures 2-3 .

[0112] As shown in Figures 3-4As can be seen, when the inner ring 12 is in the lower limit position, the inner ring 12 is combined with the disc body 11, and at this time, the disc 1 is in the ring groove shape, and the inner ring 12, together with the disc body 11 and the outer ring 13, forms an annular container to hold the material 20, so that the material 20 can normally be limited by the disc body 11, the outer ring 13 and the inner ring 12, and will not fall or leak everywhere. Because in this state, the inner ring 12 surrounds the discharge port 14 at the center of the disc body 11, and separates the material 20 on the disc body 11 from the discharge port 14 at the center of the disc body 11, so the material 20 cannot flow to the discharge port 14, that is, cannot be discharged. Therefore, this state is suitable for the process before discharging, for example, suitable for the fermentation process, and the feeding process before the fermentation starts. In order to improve the sealing between the disc body 11 and the inner ring 12 in the lower limit position, see Figure 4 In some embodiments, a sealing member 16 is arranged between the inner ring 12 and the disc body 11, so that when the inner ring 12 is combined with the disc body 11, the sealing is better, and the material 20 can be more effectively prevented from falling from the side of the inner ring 12, especially the inner ring 12 can be more effectively prevented from leaking, so that the disc 1 is especially suitable for the brewing or fermentation process of liquid or mixed solid-liquid material. As shown in Figure 2 The sealing member 16 is arranged on the inner ring 12 and rises and falls with the inner ring 12, so that it is more conducive to maintaining good sealing between the inner ring 12 and the disc body 11 after the inner ring 12 is lowered in place.

[0113] As can be seen from Figure 4 and Figure 2 When the inner ring 12 is in the upper limit position, the inner ring 12 is raised to a position above the disc body 11 and separated from the disc body 11, at this time, the inner ring 12 no longer blocks the material 20, but makes the center area of the disc body 11 originally surrounded by the inner ring 12 completely open and no longer shielded by the inner ring 12, so that the space between the lower end of the inner ring 12 and the disc body 11 provides conditions for the discharge of the material 20, and the discharge port 14 at the center of the disc body 11 is in communication with the space from the inner circle to the outer circle of the disc body 11, so that the material 20 can flow to the discharge port 14 to realize central discharge. Therefore, this state is suitable for the discharging process.

[0114] As can be seen, by raising and lowering the inner ring 12 relative to the disc body 11, the disc 1 can meet the requirements of preventing leakage and falling of the material before fermentation is completed, and can also meet the requirements of discharging after fermentation is completed, ingeniously solving the discharging problem of the ring groove-shaped disc 1, so that the ring groove-shaped disc 1 can also be conveniently discharged.

[0115] Moreover, the way of discharging by raising and lowering the inner ring 12 does not have special requirements for whether the disc 1 rotates or not, and can be applied to both the case where the disc 1 rotates and the case where the disc 1 does not rotate, so the application range is wide.

[0116] Meanwhile, the inner ring 12 is lifted relative to the disc body 11, and a center discharging mode is achieved. Compared with the outer ring discharging mode in which the material is discharged from the radial outer side, the center discharging mode is simpler and more convenient. Because the outer ring diameter of the disc body 11 is much larger than the inner ring diameter, and the size and weight of the outer ring 13 are much larger than those of the inner ring 12, the outer ring discharging mode is difficult to achieve.

[0117] Specifically, if the outer ring 13 is lifted to achieve the outer ring discharging mode, the diameter of the outer ring 13 is large, and the weight is heavy, so the lifting is difficult, the lifting mechanism for driving the outer ring 13 to lift has high requirements, and there are many safety hazards in the lifting process, which leads to a large difficulty in implementation.

[0118] If the outer ring 13 is not lifted, but a discharging door is directly arranged on the outer ring 13 to achieve the outer ring discharging mode, the requirement for whether the disc 1 rotates is high. When the disc 1 rotates, the difficulty of implementation is large. Because when the disc 1 rotates, the discharging door on the outer ring 13 also rotates around the longitudinal rotation axis, but at this time, the discharging mechanism 2 does not rotate, so it is difficult to keep alignment between the discharging mechanism 2 and the discharging door. Then, how to use the non-rotating discharging mechanism 2 to send the material on the entire disc 1 to the rotating discharging door will become a difficult problem, which leads to difficult discharging. In addition, even if the discharging mechanism 2 and the discharging door can always be aligned, but because the discharging door rotates, the material will be discharged from the entire circumference of the outer ring, so at this time, the receiving of the material will become a difficult problem. It may be necessary to arrange a receiving device around the entire circumference of the outer ring below the outer ring 13 to receive the material 20 falling from the entire circumference, but this has the problems of high cost and large space occupation. If the discharging door is arranged on the outer ring 13 to achieve the outer ring discharging mode when the disc 1 does not rotate, in order to achieve the discharging of the material on the entire disc 1, the discharging mechanism 2 needs to rotate, but the discharging mechanism 2 rotates and the disc 1 does not rotate, which means that the discharging mechanism 2 and the discharging door cannot always be aligned. Then, how to use the rotating discharging mechanism 2 to send the material on the entire disc 1 to the stationary discharging door is also a difficult problem.

[0119] It can be seen that for the ring groove-shaped disc 1, the outer ring discharging mode is difficult to achieve. In the related art, the outer ring discharging mode is mainly used because the disc 1 in the related art does not have the outer ring 13.

[0120] The center discharging mode of the ring groove-shaped disc 1 is achieved by lifting the inner ring 12 in the present disclosure, which can cleverly avoid various problems faced by the outer ring discharging mode.

[0121] On the one hand, the inner ring 12 has a small diameter and a light weight, so it is convenient to lift, and the requirement for the inner ring driving mechanism 62 for driving the inner ring 12 to lift is relatively low. A small lifting capacity of the inner ring driving mechanism 62 can meet the lifting requirement of the inner ring 12. Since the inner ring 12 has a small diameter and a light weight, it is easier to achieve a stable lifting process, and the lifting process is safer and more stable.

[0122] On the other hand, the inner ring 12 is lifted to achieve discharging, and only a discharge port 14 needs to be arranged at the center of the disc body 11. The requirement for the rotation of the disc 1 is low, and it is convenient to receive the material 20. In this case, if the disc 1 rotates, the material 20 falling from the discharge port 14 can be easily received due to the small diameter of the inner ring 12. For example, when a receiving device such as a receiving disc is arranged below the discharge 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. If the disc 1 does not rotate, the inner ring 12 can be lifted to completely remove the blockage of the inner ring 12 to the entire circumference of the inner ring, so that the rotating discharging mechanism 2 can be easily connected to the non-rotating discharge port 14. No matter where the discharging mechanism 2 rotates, the material 20 can be easily transported to the discharge port 14 for discharging. That is, there is no problem of difficult connection between the discharging mechanism 2 and the discharge port 14.

[0123] It can be seen that the center discharging of the ring groove-shaped disc 1 is achieved by lifting the inner ring 12, which can conveniently achieve the discharging of the ring groove-shaped disc 1 based on a simple structure and a low cost.

[0124] In addition, the inner ring 12 is lifted to discharge at the center. Since the blockage of the inner ring 12 can be completely removed, the discharging completeness can be improved, the discharging is more complete, and the discharging residue is reduced.

[0125] In order to conveniently transport the material 20 falling from the discharge port 14 to the downstream process, referring to Figure 2 In some embodiments, the starter machine 10 includes a discharging mechanism 63 arranged below the discharge port 14 and communicating with the discharge port 14 to transport the material 20 falling from the discharge port 14 to the radial outside of the disc 1. The discharging mechanism 63 can be one or a combination of a spiral type, a scraper type, or a belt type conveying mechanism.

[0126] Based on the arranged discharging mechanism 63, the material 20 can directly fall on the discharging mechanism 63 after falling from the discharge port 14, and is conveyed by the discharging mechanism 63 to the designated position of the downstream process, which is simple and convenient, and the connection between processes is more close, which is beneficial to improve the production efficiency. At this time, it is not necessary to additionally arrange a special material receiving device such as a receiving disc below the discharge port 14, so that the structure is relatively simple, and the floor area problem of the material receiving device such as the receiving disc does not need to be considered.

[0127] In addition, referring to Figure 5 and Figure 17 In some embodiments, the koji making machine 10 comprises a spraying device 25, which is used to spray liquid to the material 20 on the disc 1 and / or the discharging mechanism 2.

[0128] Spraying liquid to the material 20 on the disc 1 by the spraying device 25 can meet the fermentation and brewing requirements of the material and the conveying requirements when needed. For example, some materials 20 need to be added with water or other liquids to ferment well during the fermentation and brewing process, 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 another 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.

[0129] Spraying liquid to the discharging mechanism 2 by the spraying device 25 can realize the cleaning of the discharging mechanism 2, which is beneficial to keep the discharging mechanism 2 clean.

[0130] It can be seen that based on the arranged 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.

[0131] 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 conveniently spray liquid to the material 20 during the fermentation and brewing process or the discharging process.

[0132] In addition, in the related art, only direct ventilation is usually used to adjust the temperature of the material 20 during the fermentation and brewing process, the temperature adjustment mode is relatively single, the temperature adjustment effect needs to be improved, and the overall fermentation and brewing effect is affected. In view of this, 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 can also use indirect heat exchange mode to adjust the temperature of the material.

[0133] As one of the indirect heat exchange temperature adjustment modes, refer to Figures 32-33 In some embodiments, the koji making machine 10 comprises the temperature adjustment device 5, which comprises the heat exchanger 51 rotatably arranged relative to the disc 1 and extending into the material 20 on the disc 1.

[0134] The heat exchanger 51 is a heat exchanger with a heat exchange medium (such as water or other liquid) passing through the 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.

[0135] And since the heat exchanger 51 is arranged rotatably 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 play a certain stirring role for the material 20, so that the heat exchanger 51 can have both temperature adjustment function and material stirring function.

[0136] It can be seen that based on the arranged heat exchanger 51, the temperature adjustment device 5 can realize the indirect heat exchange mode, enrich the temperature adjustment mode of the koji making machine 10, and make the koji making machine 10 no longer limited to the direct ventilation heat exchange temperature adjustment mode. And 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, one machine with two functions, and rich in functions.

[0137] The temperature adjustment device 5 can rely only on the relative movement with the disc 1 to realize the material stirring function, in which case the stirring intensity of the temperature adjustment device 5 is smaller than that of the conventional material stirring mechanism 4 which both revolves relative to the disc 1 and rotates around its own axis, so it is especially suitable for materials 20 that are not suitable for intense stirring. In some fermentation brewing processes of some materials 20, intense stirring may affect the fermentation brewing effect, in which case the temperature adjustment device 5 can be used to realize the material stirring function to meet the requirement of the material 20 for a lower intensity stirring process.

[0138] In the case where the koji making machine 10 simultaneously comprises the temperature adjustment device 5 and the material stirring mechanism 4, the temperature adjustment device 5 can work together with the material stirring mechanism 4 to meet more diverse material stirring requirements and enhance the working flexibility of the koji making machine 10. For example, in the case where the material 20 requires intense stirring, the material stirring mechanism 4 can be started to stir, or the temperature adjustment device 5 and the material stirring mechanism 4 can be used together to stir, while in the case where the material 20 requires non-intense stirring, only the temperature adjustment device 5 can be used to stir without starting the material stirring mechanism 4.

[0139] As another indirect heat exchange temperature adjustment mode, see Figure 45 and Figures 32-33 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 supplies heat exchange fluid into the chamber 15, so as to adjust the temperature of the material 20 by heat exchange between the heat exchange fluid and the material 20 on the disc 1.

[0140] In the above arrangement, the disc 1 is no longer a solid disc, but has a hollow sandwich structure, and the sandwich structure can be supplied with heat exchange fluid by the first heat exchange system 81, so as to achieve temperature control of the material 20 by 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 supplied into the sandwich structure can be a liquid such as water, so as to better exchange heat with the material 20 and achieve better temperature control effect.

[0141] As can be seen, based on the first heat exchange system 81 arranged, the indirect heat exchange temperature adjustment mode based on heat exchange between the heat exchange medium and the material 20 can also be achieved, which enriches the temperature adjustment mode of the koji making machine 10 and makes the koji making machine 10 no longer limited to the direct ventilation temperature adjustment mode.

[0142] In the above arrangement, 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.

[0143] For example, see Figure 34 In some embodiments, the chamber 15 comprises a first cavity 151 arranged inside the disc body 11, and at this time, the disc body 11 has a sandwich structure. Since the material 20 is mainly accumulated on the disc body 11, the disc body 11 is arranged to have a sandwich structure and the heat exchange fluid is supplied into the sandwich structure of the disc body 11, which can meet the heat exchange demand of most of the material 20 and achieve better temperature adjustment effect. See Figure 46 and Figures 34-37 The inside of the first cavity 151 in 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 achieve regional heat exchange, and since each region can independently exchange heat, the failure of a certain region will not affect the heat exchange of other regions, which has high reliability and is convenient to maintain. This regional heat exchange mode of the disc body 11 is suitable for the case where the disc 1 rotates (see Figure 46), also applies to the case where the disc 1 does not rotate (see Figures 32-33 Each heat exchange cavity 153 can be arranged in sequence along the circumference of the disc 1, 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.

[0144] For another example, back to Figures 32-33 In some embodiments, the chamber 15 includes a second cavity 152 arranged inside the outer ring 13, and in this 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 better temperature regulation effect.

[0145] For another example, continuing to refer to Figures 32-34 In some embodiments, the chamber 15 includes both the first cavity 151 and the second cavity 152, and in this case, both the disc body 11 and the outer ring 13 are 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, thus helping to prevent temperature unevenness of the material 20 in the circumferential or height direction, achieving a more uniform temperature regulation effect.

[0146] In the case where the chamber 15 includes both the first cavity 151 and the second cavity 152, the second cavity 152 can be in communication with the first cavity 151, and the heat exchange fluid provided by the first heat exchange system 81 can flow from the first cavity 151 to the second cavity 152, and then flow out of the disc 1 from the second cavity 152. In this way, the heat exchange fluid can first exchange heat with the material 20 in the disc body 11, and then exchange heat with the material 20 in the outer ring 13, which is a heat exchange mode of first the disc body 11 and then the outer ring 13, more in line with the characteristics of the material 20 having a large flat area and a small thickness, and the heat exchange demand of the disc body 11 being greater, helping to achieve better heat exchange effect, and this heat exchange mode 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. In this case, the first heat exchange system 81 can be arranged below the disc body 11, and 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.

[0147] When the disc 1 rotates, how to arrange the first heat exchange system 81 to avoid entanglement of the pipeline during rotation of the disc 1 is a difficult problem.

[0148] In order to solve the entanglement problem of the pipeline of the first heat exchange system 81 during rotation of the disc 1, refer to Figure 33In some embodiments, when the disc 1 is rotatable, the chamber 15 comprises a first cavity 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 inlet annular groove 813 and an outlet annular groove 814 which are separated from each other. The second shell 812 is provided with an inlet port 818 and an outlet port 819 which are separated from each other. The inlet port 818 communicates with the first cavity 151 through the inlet annular groove 813. The outlet port 819 communicates with the first cavity 151 through the outlet annular groove 814. The inlet port 818 is connected with an inlet pipe 81a which communicates with a heat exchange fluid supply source. The outlet port 819 is connected with an outlet pipe 81b for discharging the heat exchange fluid.

[0149] Based on the above arrangement, the heat exchange fluid enters the first cavity 151 through the inlet port 818 and the inlet annular groove 813, and flows out to the outside from the outlet annular groove 814 and the outlet port 819 after flowing through the disc 1. During the whole process, since the first shell 811 provided with the inlet annular groove 813 and the outlet annular 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 place and do not rotate with the disc 1, and at the same time the heat exchange fluid can enter and exit the first cavity 151 through the inlet annular groove 813 and the outlet annular groove 814 to realize the interlayer heat exchange. It can be seen that the above arrangement 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.

[0150] Since the space below 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, so that the arrangement and installation of the first heat exchange system 81 are conveniently realized.

[0151] Among them, referring to Figures 33-35 In some embodiments, the inlet annular groove 813 is located radially inward of the outlet annular groove 814, so that the layout is more compact and reasonable, and after the heat exchange fluid enters the first cavity 151, it flows first to the radially inner side and then to the radially outer side, so as to orderly realize the temperature regulation of the material 20 at each part of the disc body 11.

[0152] In order to guide the orderly flow of the heat exchange fluid in the disc body 11, referring to Figures 34-37In 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 in communication 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.

[0153] Based on the above arrangement, 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 entire disc body 11, thereby fully exchanging heat with the material 20 on the disc body 11.

[0154] Here, taking the case where the inlet ring groove 813 is located radially inside the outlet ring groove 814 as an example, the flow process of the heat exchange fluid based on the above arrangement is described.

[0155] Referring to Figure 35 When the inlet ring groove 813 is located radially inside the outlet ring groove 814, the heat exchange fluid flowing into the inlet ring 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 on the side of the first partition plate 154 along the circumferential direction of the disc 1 (the space on the side of the inlet 157, which is indicated as the first space 15a in Figure 35 Since the heat exchange fluid is blocked by the second partition plate 155, it cannot flow radially outward of the disc 1 but only flows radially inward of the disc 1. When the heat exchange fluid flows to a position close to the inner ring 12, it flows into the space of the first cavity 151 on the other side of the first partition plate 154 along the circumferential direction of the disc 1 (the space on the other side of the inlet 157, which is indicated as the second space 15b in Figure 33 After the turn, the heat exchange fluid flows radially outward of the disc 1 and finally flows to the outlet 158 and then flows out of the disc body 11 to the outside of the disc body 11 through the outlet 158. As shown in Figures 34-35 The heat exchange fluid flowing out of the disc body 11 flows through the outlet ring groove 814, the outlet 819 and the outlet pipe 81b in sequence and then flows back to the heat exchange fluid supply source to realize the circulation of the heat exchange fluid.

[0156] When the second cavity 152 is provided 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 vicinity of the outer ring 13, as shown in Figures 35-36As shown, the heat exchange fluid will first flow into the second cavity 152 through the inlet I of the second cavity 152, and then flow back into the first cavity 151 from the outlet O of the second cavity 152 after flowing through the second cavity 152, and then flow towards the radial inner side until it reaches the outlet 158, and then flow out of the disc body 11. At this time, there is no gap between the first partition plate 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 to the second cavity 152 and directly flowing to the outlet 158.

[0157] In the case where the second cavity 152 is not provided in the outer ring 13, the heat exchange fluid flowing from the radial inner side of the disc body 11 to the radial outer side will, as shown, Figures 32-33 not flow to the second cavity 152, but will directly turn back through the gap between the first partition plate 154 and the outer ring 13, and then flow towards the radial inner side until it reaches the outlet 158, and then flow out of the disc body 11. That is, in this case, a gap is provided between the first partition plate 154 and the outer ring 13.

[0158] As can be seen, when the inlet annular groove 813 is located radially inward of the outlet annular groove 814, based on the first partition plate 154 and the second partition plate 155 provided, the heat exchange fluid can be guided to flow in the order of first flowing towards the radial inner side, then flowing towards the radial outer side, and then flowing towards the radial inner side again, which facilitates the heat exchange fluid to flow through each part of the disc body 11 in an orderly manner, and to exchange heat with the material 20 at each part of the disc body 11. In addition, in the case where the second cavity 152 is provided in the outer ring 13, it is also more convenient for the heat exchange fluid to flow from the first cavity 151 to the second cavity 152, and to realize the heat exchange process of first flowing through the disc body 11 and then flowing through the outer ring 13.

[0159] In the above embodiments, in order to improve the sandwich heat exchange effect, as shown in Figure 33 in some embodiments, baffles 156 are provided in the chamber 15 to guide the heat exchange fluid entering the chamber 15 to flow in a zigzag manner. As shown in Figure 33 a plurality of baffles 156 can be arranged side by side, and adjacent two baffles 156 can be arranged on opposite two side walls of the chamber 15 and partially staggered in opposite directions of the two side walls to form a zigzag flow channel to guide the heat exchange fluid to flow in a zigzag manner in the chamber 15. For example, as shown in Figure 38In some embodiments, a plurality of groups of baffles 156 can be arranged in the first cavity 151 inside the disc 1, each group of baffles 156 comprising a plurality of baffles 156 arranged at the same circumferential position, the baffles 156 at the same circumferential position being arranged side by side along the radial direction of the disc 1, and adjacent two baffles 156 being connected to the upper and lower sidewalls of the first cavity 151 respectively and being arranged in a staggered manner in the up-down direction to form an S-shaped baffle flow channel. The baffle flow can prolong the flow time of the heat exchange fluid in the cavity 15, so that the heat exchange fluid can exchange heat with the material 20 more fully, thus improving the temperature control effect on the material 20.

[0160] In addition, as another kind of indirect heat exchange temperature control mode, referring to Figures 1-46 In some embodiments, the koji making machine 10 comprises a second heat exchange system 82, which comprises a liquid storage pool 821 arranged below the disc 1 and used for containing liquid, and the disc 1 is at least partially immersed in the liquid in the liquid storage pool 821. In this way, an immersion heat exchange process can be realized, and the temperature of the material 20 can be adjusted by heat exchange between the liquid in the liquid storage pool 821 and the material 20 on the disc 1. This indirect heat exchange temperature control mode is simple and easy to implement, and can be conveniently applied whether the disc 1 rotates or not.

[0161] Next, the embodiments shown in Figures 1-35 will be further described.

[0162] First, the first embodiment shown in Figures 1-2 will be introduced.

[0163] Referring to Figures 1-2 , in the first embodiment, the koji making machine 10 comprises a disc 1, a discharging mechanism 2, a feeding mechanism 3, a material 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.

[0164] The disc 1 is rotatably arranged on the frame 91 and contains the material 20 to be fermented or brewed inside. The discharging mechanism 2 is used to transport the brewed or fermented material 20 from the disc 1 to a designated position in the next process. The feeding mechanism 3 is used to transport the material 20 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 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 arranged, and cold or 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 and temperature control of the material 20.

[0165] In summary, the koji-making machine 10 of this embodiment is an assembly of devices in which 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 means of the turning mechanism 4, the temperature control 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 through the discharge mechanism 2.

[0166] The following sections will introduce each component in detail.

[0167] Figures 1-2 The structure of disk 1 in this embodiment is shown. For example... Figures 3-4 As shown, in this embodiment, the disk 1 is a grooved disk, comprising a disk body 11, an inner ring 12, and an outer ring 13. A discharge port 14 is located at the center of the disk body 11. The outer ring 13 and the inner ring 12 are respectively disposed on the outer and inner rings of the disk body 11. The outer ring 13 is inseparably connected to the disk body 11, forming an integral structure. The inner ring 12 is separably coupled to the disk body 11, forming a separate structure. Specifically, when the inner ring 12 is in its lower limit position, it is coupled to the disk body 11; when it is in its upper limit position, it is separated from the disk body 11. Furthermore, the coupling... Figures 2-4 As can be seen, in this embodiment, the lower end of the inner ring 12 is provided with a sealing element 16. When the inner ring 12 is engaged with the disc body 11, the sealing element 16 seals the gap between the inner ring 12 and the disc body 11, so that when the inner ring 12 is in the lower limit position, the seal between it and the disc body 11 is good and there is no leakage. In this way, the disc 1 is suitable for holding liquid, solid-liquid mixture or solid material 20, so as to complete the fermentation and brewing process of the corresponding material 20.

[0168] The raising and lowering of the inner ring 12 is accomplished by the inner ring drive mechanism 62. The inner ring drive mechanism 62 is connected to the inner ring 12 and is used to drive the inner ring 12 to rise and fall between the lower limit position and the upper limit position, so as to realize the engagement and disengagement between the inner ring 12 and the disc body 11. Figures 2-4 The structure of the inner ring drive mechanism 62 is shown.

[0169] like Figures 2-3 As shown, in this embodiment, the inner ring drive mechanism 62 includes a lifting drive mechanism 621, which is drivenly connected to the inner ring 12 to drive the inner ring 12 to rise and fall. Specifically, as... Figure 2As shown, in this embodiment, a mounting bracket 625 is fixedly installed below the top of the frame 91. A lifting drive mechanism 621 is mounted on the mounting bracket 625 and includes a drive cylinder (e.g., a pneumatic cylinder, electric cylinder, or hydraulic cylinder). The cylinder barrel of the drive cylinder is fixed to the mounting bracket 625, and the cylinder rod extends below the mounting bracket 625 and is drivenly connected to the inner ring 12 via a first plate 623 and a second plate 624. The first plate 623 is connected to the cylinder rod of the drive cylinder, and the second plate 624 is disposed on the surface of the inner ring 12 near the center of the disk 1, protruding from the inner ring 12 towards the center. Furthermore, the second plate 624 is located above the first plate 623 and overlaps the first plate 623. Thus, when the cylinder rod of the drive cylinder retracts, as... Figure 4 The middle dashed line part and Figure 2 As shown, the first plate 623 pushes the second plate 624 upward, thereby lifting the inner ring 12 and causing it to rise. Meanwhile, when the cylinder rod of the drive cylinder extends, as... Figure 3 The solid line section and Figures 2-4 As shown, when the first plate 623 falls, the second plate 624 and the inner ring 12 will also fall under the influence of gravity until they return to their lower limit position. The second plate 624 then reattaches to the first plate 623, thus lowering the inner ring 12. It is evident that the lifting drive mechanism 621 can drive the inner ring 12 to rise and fall. Of course, the structure of the lifting drive mechanism 621 can have other variations. For example, besides using a drive cylinder as the power mechanism, the lifting drive mechanism 621 can also use other mechanisms such as a linear motor as the power mechanism.

[0170] In addition, such as Figures 2-4 As shown, in this embodiment, the inner ring drive mechanism 62 includes not only the lifting drive mechanism 621, but also a guide member 622. The guide member 622 is connected to the inner ring 12 and is used to guide the inner ring 12 during the lifting drive mechanism 621 driving the inner ring 12 to rise and fall. Specifically, as shown... Figures 2-4 As shown, in this embodiment, a plurality of guide members 622 are disposed on the mounting bracket 625 and extend vertically downward through the mounting bracket 625 to connect with the first plate 623. For example, in Figures 5-6 In this design, two guide members 622 are respectively arranged on both sides of the lifting drive mechanism 621, and both vertically pass through the mounting bracket 625 and are connected to the first plate 623. Thus, during the lifting drive mechanism 621's movement of the inner ring 12, the guide members 622 can act as guides, guiding the inner ring 12 to move more smoothly. The guide member 622 can be a guide rod, or it can be a combination of a guide rod and a linear bearing, a linear guide rail and a slider, or an oil-free bushing and a guide rod, etc.

[0171] In the production process, before the material 20 enters the disc 1, the inner ring 12 is lowered to the lower limit position and contacts the disc body 11, and the gap between the two is sealed by the sealing element 16. At this time, the inner ring 12, together with the disc body 11 and the outer ring 13, forms a sealed container that can be used to hold liquid, solid-liquid mixed or solid materials. After the material 20 is sent to the disc 1 by the feeding mechanism 3, the inner ring 12 is always in the lower limit position during the entire subsequent brewing and fermentation process to prevent material leakage. When the material 20 is fermented or brewed, the inner ring 12 is raised upward, so that the discharge port 14 is in communication with the space of the disc 1 for holding the material 20, thereby facilitating the feeding mechanism 2 to transport the material 20 to the discharge port 14 to realize central discharge.

[0172] Figures 5-6 The structure of the discharge mechanism 2 in this embodiment is shown. Referring to Figure 2 In this embodiment, the discharge mechanism 2 does not rotate with the disc 1 and includes a conveyor 21 and a discharge lifting mechanism 22. The conveyor 21 is arranged above the disc body 11 and extends in the radial direction of the disc 1, that is, the axis of the conveyor 21 is along the radial direction of the disc 1. The conveyor 21 can rotate along its own rotation axis, so as to convey the material in the radial direction of the disc 1 and discharge the material. The discharge lifting mechanism 22 is provided on the frame 91 and is drivingly connected with the conveyor 21 to drive the conveyor 21 to lift, so that the conveyor 21 can be lifted relative to the disc 1 to control the contact or separation of the conveyor 21 with the material 20, thereby meeting different requirements at different stages.

[0173] When discharge is not needed, for example, during feeding or fermentation brewing, the discharge lifting mechanism 22 can drive the conveyor 21 to rise, so that the conveyor 21 is separated from the material 20 and does not contact the material 20, to prevent the conveyor 21 from affecting the normal feeding or fermentation brewing process. When discharge is needed, the discharge lifting mechanism 22 drives the conveyor 21 to descend, so that the lower edge of the conveyor 21 closely abuts the upper surface of the disc body 11, so that the conveyor 21 fully contacts the material 20. At this time, the conveyor 21 is started to convey the material 20 towards the inner side of the disc 1, so as to send the material 20 to the discharge port 14, which falls downward from the discharge port 14. With the rotation of the disc 1, the material 20 on the entire disc 1 can be sent to the discharge port 14 to complete the discharge process.

[0174] The material 20 falling from the discharge port 14 can be caught by a receiving device such as a receiving tray, and then transported to a designated position of a downstream process by a conveying device. In this case, since the discharge port 14 is at the center of the disc 1, the corresponding radial range is small, and therefore the diameter of the receiving tray can be small without occupying a large space.

[0175] However, in order to further facilitate the transfer of the material to the downstream process, referring to Figure 5In this embodiment, no receiving device such as a receiving tray is arranged below the discharge port 14, but a discharging mechanism 63 is arranged below the discharge port 14, communicates with the discharge port 14, and extends along the radial direction of the disc 1. In this way, the material 20 falling from the discharge port 14 can directly fall onto the discharging mechanism 63 and be conveyed by the discharging mechanism 63 to the outside of the radial direction of the disc 1. In this way, since no receiving tray needs to be arranged, the ground space occupied by the receiving tray can be saved, and since the material 20 does not need to be first dropped into the receiving tray and then transferred outward, but can be directly conveyed outward by the discharging mechanism 63, the material conveying is more convenient, the connection between processes is more close, and the overall production efficiency is improved.

[0176] In addition, as shown in Figure 7 and Figure 5 , in this embodiment, the discharging mechanism 2 is also provided with a spraying device 25, which includes a liquid spraying pipe 251 that sprays liquid such as water towards the material 20 and the conveyor 21 to add liquid to the material 20 or to clean the conveyor 21, so that the material 20 is more easily fermented and brewed or conveyed, or so that the conveyor 21 is more clean. As shown in Figures 5-6 , a plurality of nozzles 252 can be arranged on the liquid spraying pipe 251 to further improve the spraying effect.

[0177] As shown in Figures 7-8 , in this embodiment, the conveyor 21 is specifically a screw conveyor 23. However, it can be understood that the conveyor 21 can also have other variants, for example, as shown in Figures 9-10 , the conveyor 21 can also be a scraper conveyor 24.

[0178] Figures 9-10 The structure of the feeding mechanism 3 in this embodiment is shown. As shown in Figure 10 , in this embodiment, the feeding mechanism 3 is arranged above the disc body 11 and does not rotate with the disc 1, and includes a first conveying device 31 and a second conveying device 32. The first conveying device 31 and the second conveying device 32 are both arranged on a feeding frame 33 connected with 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 is provided with a feeding port 34. 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 is provided with a distributing port 35. Specifically, as shown in Figure 10As shown, the second conveying device 32 is provided with a roller 39 below, which is in contact with the feeding frame 33, so that the roller 39 rotates, that is, the second conveying device 32 can move on the feeding frame 33 along the radial direction of the disc 1. In this way, the second conveying device 32 can move along the radial direction of the disc 1 relative to the first conveying device 31, so that the feeding mechanism 3 as a whole can be telescopic, and the material 20 can be conveyed to different positions of the disc 1.

[0179] When feeding is needed, the material 20 falls from the upper conveying equipment into the feeding port 34, and then falls onto the first conveying device 31, and then falls from the first conveying device 31 to the second conveying device 32, and then falls from the material distribution port 35 of the second conveying device 32 to the disc 1. Since the second conveying device 32 can move along the radial direction relative to the disc 1, the second conveying device 32 can convey the material 20 to different radial positions of the disc 1. Since the disc 1 rotates relative to the feeding mechanism 3, the feeding mechanism 3 can deliver the material 20 to different circumferential positions of the disc 1, and thus, under the cooperation of the feeding mechanism 3 and the disc 1, the material 20 can be uniformly fed to the entire disc 1.

[0180] As shown in the embodiment, the first conveying device 31 and the second conveying device 32 are specifically belt conveying devices 36, but it can be understood that, as a variant, as shown in Figure 11 and Figure 12 and Figures 13-14 shown, the first conveying device 31 and the second conveying device 32 can also be screw conveying devices 37 or scraper conveying devices 38.

[0181] Figures 13-14 The structure of the material turning mechanism 4 in this embodiment is shown. As shown in Figure 13 In this embodiment, the material turning mechanism 4 is located above the disc body 11 and does not rotate with the disc 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 uniformly reaches the required temperature, humidity and strain environment. The material turning lifting mechanism 42 is arranged on the frame 91 and is drivingly connected with the material turning device 41 to drive the material turning device 41 to ascend and descend, so as to control whether the material turning device 41 is in contact with the material 20. When the material turning device 41 descends to be in contact with the material 20, the material 20 can be turned to realize the material turning function. After the material turning device 41 ascends above the material 20, it is no longer in contact with the material 20 and cannot turn the material 20.

[0182] During production, 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 ascend and descend at other heights below the highest point, the material turning device 41 can turn the material 20 at different heights.

[0183] As shown in Figures 15-16 In this embodiment, the material turning device 41 is specifically a horizontal turning device 43, and the rotation axis of the horizontal turning device 43 extends horizontally. However, the structure of the material turning device 41 is not limited thereto. For example, as shown in Figure 17 The material turning device 41 can also be a vertical screw turning device 44, which includes a plurality of screw turning members with rotation axes extending vertically. For another example, although not shown, the material turning device 41 can also be a rake turning device. Alternatively, according to the characteristics of the material or the process requirements, the material turning device 41 can adopt a combination of two or more of the horizontal turning device 43, the vertical screw turning device 44, or the rake turning device.

[0184] Figure 17 The structure of the temperature adjusting device 5 in this embodiment is shown. As shown in Figures 18-19 In this embodiment, the temperature adjusting device 5 is arranged on the frame 91 and does not rotate with the disc 1. The temperature adjusting device 5 includes a support 57 and a heat exchanger 51. The support 57 is fixedly connected to the frame 91. The heat exchanger 51 is arranged on the support 57 and includes a main pipe 52 and a plurality of branch pipes 53. The main pipe 52 is provided with a heat exchange medium inlet 54 and a heat exchange medium outlet 55 for the heat exchange medium to enter and exit the heat exchanger 51, respectively. The plurality of branch pipes 53 are in communication with the main pipe 52 in parallel 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 adjust the temperature of the material 20. Moreover, since the disc 1 rotates and the heat exchanger 51 does not rotate therewith, there is relative rotation between the disc 1 and the heat exchanger 51, and thus the heat exchanger 51 also functions as a material turning device. It can be seen that the heat exchanger 51 in this embodiment can both control the temperature and turn the material, and thus can serve two purposes with one device.

[0185] Figures 18-19 The structure of the heat exchanger 51 is further shown. As shown in Figures 20-21 In this embodiment, the branch pipes 53 of the heat exchanger 51 are substantially columnar, hollow inside, and have the same cross-sectional size from top to bottom. Of course, the shape of the branch pipes 53 can also have other variations. For example, as shown in Figures 22-23 It can be seen that in some embodiments, the branch pipes 53 are substantially U-shaped, hollow inside, and have the same cross-sectional size from top to bottom. For another example, as shown in Figures 24-25 It can be seen that in some other embodiments, the branch pipes 53 are substantially rake-shaped, hollow inside, and have gradually increasing cross-sectional size from top to bottom. For yet another example, as shown in Figures 26-27 It can be seen that in yet some other embodiments, the branch pipes 53 are substantially plow-shaped, hollow inside, have the same cross-sectional size from top to bottom, and are provided with protrusions 56 on the outer surface. The protrusions 56 are substantially plow-shaped, with a smooth upper part and a sharp lower part.

[0186] Figures 26-27 The structure of the rotating disc mechanism 61 in this embodiment is shown. Referring to Figures 28-29 In this embodiment, the disc 1 is rotatably arranged on the frame 91 and is driven to rotate by the rotating disc mechanism 61. Specifically, the middle part of the disc 1 is supported by the center bearing 614 (for example, a self-aligning roller bearing), and the outer edge is supported by the first supporting roller 613, so that the disc 1 can rotate relative to the frame 91 about the longitudinal rotation axis located at the center of the disc 1. The rotating disc mechanism 61 includes a rotating disc driving mechanism 611 and a first transmission mechanism 612. The rotating disc driving mechanism 611 is drivingly connected to the disc 1 through the first transmission mechanism 612 for driving the disc 1 to rotate. The rotating disc driving mechanism 611 is arranged at the outer edge of the disc 1 and includes one, two or more motors. The first transmission mechanism 612 is arranged at the outer edge of the disc 1 and includes a gear and a tooth or pin located at the entire circumference of the disc 1. The tooth or pin is drivingly connected to the rotating disc driving mechanism 611 through the gear, so that when the rotating disc driving mechanism 611 is started, the disc 1 as a whole can be automatically rotated about the longitudinal rotation axis. In this way, when the rotating disc driving mechanism 611 is started, the disc 1 as a whole can be automatically rotated about the longitudinal rotation axis.

[0187] Since the disc 1 can rotate about the longitudinal rotation axis under the action of the rotating disc mechanism 61, while the discharging mechanism 2, the feeding mechanism 3, the turning mechanism 4 and the temperature adjusting device 5 do not rotate about the longitudinal rotation axis, the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the turning mechanism 4 and the temperature adjusting device 5 and the disc 1 about the longitudinal rotation axis can be realized, so that as the disc 1 rotates, the discharging mechanism 2, the feeding mechanism 3, the turning mechanism 4 and the temperature adjusting device 5 can reach different circumferential positions of the disc 1, and discharging, feeding, turning and temperature adjusting are performed at different circumferential positions, finally realizing the discharging, feeding, turning and temperature adjusting of the entire circumference of the disc 1.

[0188] The rotation of the disc 1 not only facilitates the realization of the discharging, feeding and turning of the entire circumference, but also is beneficial to the uniform fermentation of the material 20. Moreover, if the material 20 needs to be stationary during the fermentation process, the disc 1 can remain stationary and not rotate during the entire fermentation process or a certain period of time in the fermentation process.

[0189] Figures 28-29 The structure of the ventilation device 7 in this embodiment is shown. Referring to Figures 28-29In 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, so that the cold and hot air passes through the material 20 and directly exchanges heat with the material 20 to adjust the temperature of the material 20. The ventilation device 7 includes a fan 71, an air pipe 72, a heat exchanger 73, and an adjusting valve 74. The fan 71 is connected with the inside and outside of the chamber through the air pipe 72 to drive the air into the koji making chamber 78. The air pipe 72 is provided with the adjusting valve 74 and the heat exchanger 73. The adjusting valve 74 adjusts the air volume. The heat exchanger 73 adjusts the temperature of the air flowing into the chamber.

[0190] As a variation of the ventilation device 7 shown in Figures 30-31 , the heat exchanger 73 can not be provided in the air pipe 72, and a heater or hot steam can be used to heat the air, or cooling water or a refrigeration air conditioner can be used to cool the air, or the fan 71 can be directly connected with the chamber without the air pipe 72 and the heat exchanger 73. In addition, as shown in Figures 32-35 , when the koji making chamber 78 is a non-closed space and the koji making chamber 78 is connected with the outside of the chamber through the window 75, the ventilation device 7 can only include the fan 71, and during the production process, the ventilation condition can be controlled by controlling the opening and closing of the fan 71 and the opening degree of the window 75.

[0191] Figures 32-35 The structure of the first heat exchange system 81 and the disc 1 matched with the first heat exchange system 81 in this embodiment is shown. As shown in Figures 32-33 , in this embodiment, the disc body 11 and the outer ring 13 of the disc 1 are respectively provided with a first cavity 151 and a second cavity 152, so that the disc body 11 and the outer ring 13 both become sandwiched structures. The first heat exchange system 81 is arranged below the disc body 11 and is used to introduce heat exchange fluid into the first cavity 151 and the second cavity 152, so as to adjust the temperature of the material 20 by using the heat exchange between the heat exchange fluid and the material 20.

[0192] As shown in Figure 33As 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 arranged on the lower surface of the disc body 11, so that the first shell 811 can rotate with the disc 1. The second shell 812 is arranged below the first shell 811, and a bearing 816 is arranged between the first shell 811 and the second shell 812. The outer ring of the bearing 816 cooperates with the second shell 812, and the inner ring of the bearing 816 cooperates with the first shell 811, so that the second shell 812 can not rotate when the first shell 811 and the disc 1 rotate. The second shell 812 is provided with a sealing ring 815 to seal the gap between the second shell 812 and the first shell 811, preventing 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 cavity 151 inside the disc body 11 through the second shell 812 and the first shell 811. The inlet pipe 81a and the outlet pipe 81b are both provided with control valves 817 to adjust the flow of the heat exchange fluid. Although not shown, it is understood that a pump can be arranged on the inlet pipe 81a and / or the outlet pipe 81b to drive the flow of the heat exchange fluid.

[0193] Specifically, as shown in the drawings, Figure 33 In this embodiment, the second shell 812 is provided with an inlet port 818 and an outlet port 819 which are separated from each other. The inlet pipe 81a and the outlet pipe 81b are connected to the inlet port 818 and the outlet port 819 respectively. In the radial direction of the disc 1, the inlet port 818 is closer to the inner ring 12 than the outlet port 819, at this time, the inlet port 818 is located radially inside the outlet port 819, and the inlet pipe 81a is located radially inside the outlet pipe 81b. At the same time, as shown in the drawings, Figures 34-35 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 inlet ring groove 813 and the outlet ring groove 814 are both circular ring grooves, and are arranged in sequence along the direction from the inner ring 12 to the outer ring 13, and are both in communication with the first cavity 511 inside the disc body 11 through the inlet port 818 and the outlet port 819, and the inlet pipe 81a and the outlet pipe 81b. In this way, the heat exchange fluid flowing from the inlet pipe 81a to the disc 1 can flow into the disc body 11 in sequence through the inlet port 818 and the inlet ring groove 813, and the heat exchange fluid flowing through the disc body 11 and the outer ring 13 can flow out in sequence through the outlet ring groove 814, the outlet port 819 and the outlet pipe 81b.

[0194] Since the second shell 812 connected by the inlet pipe 81a and the outlet pipe 81b does not rotate with the disc 1, the inlet pipe 81a and the outlet pipe 81b can not rotate during the rotation of the disc 1, so the inlet pipe 81a and the outlet pipe 81b will not be wound due to the rotation of the disc 1.

[0195] 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.

[0196] 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 34-35 As shown, 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.

[0197] Specifically, such as Figures 34-35 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 Figure 35 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 35 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... Figures 36-37As shown, in this embodiment, the first space 15a is in communication with the flow outlet O of the second cavity 152 located inside the outer ring 13 at the radially outer end, and the second space 15b is in communication with the flow inlet I of the second cavity 152 at the radially outer end. And, a plurality of baffles 156 are arranged in the first space 15a and the second space 15b, so that a zigzag flow channel is formed in the first space 15a and the second space 15b, and the heat exchange fluid zigzag flows in the first space 15a and the second space 15b.

[0198] Based on the above arrangement, during the rotation of the disc 1, the heat exchange fluid flowing into the ring groove 813 from the inlet pipe 81a can flow into each heat exchange cavity 153 through the inlet 157 of each heat exchange cavity 153, and the heat exchange fluid entering each heat exchange cavity 153 first enters the first space 15a. In the first space 15a, the heat exchange fluid cannot flow to the outlet 158 radially outward due to the blocking of the second partition plate 155, but can only flow radially inward to the disc 1 first, and when it flows to the inner end of the first partition plate 154, it flows into the second space 15b through the gap between the first partition plate 154 and the inner ring 12, and turns back in the second space 15b to flow radially outward to the disc 1. When the heat exchange fluid flows radially outward to the outer end of the first partition plate 154 in the second space 15b, since there is no gap between the first partition plate 154 and the outer ring 13, the heat exchange fluid will not flow directly back into the first space 15a, but will flow into the second cavity 152 through the flow inlet I of the second cavity 152, and after flowing through the second cavity 152, it will flow back into the first space 15a from the flow outlet O of the second cavity 152, and then flow to the outlet 158, and then flow to the discharge pipe 81b from the outlet 158.

[0199] As can be seen, based on the above arrangement, 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 flow radially outward. The whole flow process is orderly and controllable, and can orderly control the temperature of the materials 20 at different radial positions and different height positions on the disc 1, which is beneficial to make the materials 20 on the whole disc 1 reach a temperature that can better meet the process requirements.

[0200] Figures 36-37 It is shown that when the second cavity 152 is not arranged inside the outer ring 13, the flow path inside the disc body 11. As shown in FIG. 6, the disc body 11 is arranged with a plurality of first cavities 151, and each first cavity 151 is in communication with the flow inlet I of the second cavity 152 at the radially outer end and the flow outlet O of the second cavity 152 at the radially inner end. And, a plurality of baffles 156 are arranged in each first cavity 151, so that a zigzag flow channel is formed in each first cavity 151, and the heat exchange fluid zigzag flows in each first cavity 151. Figures 32-37As 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.

[0201] As Figure 38 The replacement of the first heat exchange system 81 shown is as follows: Figures 39-46 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.

[0202] Next, we will introduce... Figures 39-46 The second embodiment is shown.

[0203] like Figures 1-37 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 39-42 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.

[0204] 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.

[0205] like Figures 39-42 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 39-42 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.

[0206] Specifically, such as Figure 45 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.

[0207] 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.

[0208] 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.

[0209] Furthermore, since the 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 46As shown in the second embodiment, the disc 1 only the disc body 11 adopts the sandwich structure, and the first cavity 151 is arranged in the disc body 11, and the inner ring 12 and the outer ring 13 are not arranged with the sandwich structure, and the first heat exchange system 81 no longer comprises the first shell 811 and the second shell 812 which can relatively rotate, but comprises the inlet pipe 81a and the outlet pipe 81b which are 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 rotating winding, which is simple and convenient.

[0210] Figure 46 The flow path schematic diagram of the disc body 11 in the embodiment is shown. As shown in the figure, Figure 43 In the embodiment, the first cavity 151 in the disc body 11 is still divided into a plurality of heat exchange cavities 153 which are arranged along the circumference of the disc 1 and cover the entire circumference of the disc body 11. And the bottom wall of each heat exchange cavity 153 is provided with an inlet 157 and an outlet 158 which are in communication with the inlet pipe 81a and the outlet pipe 81b respectively. At the same time, a plurality of baffles 156 are arranged in each heat exchange cavity 153 to form a baffling flow channel. In this way, the heat exchange fluid in the inlet pipe 81a can enter the heat exchange cavity 153 through the inlet 157, and after multiple turns in each heat exchange cavity 153, flow out of the outlet 158 to the outlet pipe 81b, and finally realize the temperature regulation of the material 20 on the entire disc body 11.

[0211] In addition, as shown in the figures, Figure 44 and Figures 43-44 In the second embodiment, the inner ring 12 of the disc 1 can still be lifted and lowered relative to the disc body 11 under the drive of the inner ring driving mechanism 62, but the setting mode of the inner ring driving mechanism 62 is slightly different from that of the first embodiment. As shown in the figure, Figures 43-44 In the second embodiment, the inner ring driving mechanism 62 is no longer hung below the frame 91, but is installed at the discharge port 14 located at the center of the disc body 11, and is connected with the inner ring 12 through the connecting plate 626. Specifically, as shown in the figure, ​ In the embodiment, the lifting and driving mechanism 621 of the inner ring driving mechanism 62 is arranged below the inner ring 12. The guide 622 passes through the side wall of the discharge port 14 from bottom to top. The connecting plate 626 is connected to the side surface of the inner ring 12 which faces the longitudinal center line of the disc 1. The two ends of the guide 622 are connected with the lifting and driving mechanism 621 and the connecting plate 626 respectively. In this way, the lifting and driving mechanism 621 is connected with the inner ring 12 through the guide 622 and the connecting plate 626, so that the lifting and driving mechanism 621 can realize the lifting of the inner ring 12 by lifting the inner ring 12. After the inner ring 12 is lifted, the discharging mechanism 2 can transport the material 20 to the discharge port 14 to realize the central discharging.

[0212] In summary, the starter machine 10 provided by the embodiments of the present disclosure can conveniently realize the discharging of the ring groove-shaped disc, and can more effectively control the material temperature, and achieve better fermentation brewing effect.

[0213] The above merely describes exemplary embodiments of the present disclosure, and is not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
