DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the brewing industry, to enable seamless automation of the entire process of koji cultivation and thus shorten the single-batch koji production cycle, this embodiment provides a brewing system 100, as referenced. Figure 1 The system includes multiple koji trays 1, a cooking device 5, an inoculation and turning device, at least one koji-making device, and a transfer cart 2. The koji trays 1 are used to receive materials. After the materials are moistened by the moistening machine 4, a pre-set volume of moistened material is evenly spread across the entire inner surface of the koji tray 1 by the spreading machine 3. The materials then sequentially complete each stage of koji cultivation within the koji tray 1 until cultivation is complete. The koji product is then scraped out of the koji tray 1 and transferred to other processes or equipment. In this embodiment, at least some of the koji trays 1 have a height of 8-15 cm, preferably around 10 cm. Compared to the large discs of existing disc koji-making machines, this allows the materials in the koji trays 1 to have more sufficient contact with the moisture and air in the cultivation environment, thereby further improving the efficiency and quality of koji cultivation. Here, the height of the koji tray 1 refers to the height from the bottom to the top of the koji tray 1, which is equivalent to the thickness of the koji tray 1. The cooking equipment 5 will first cook the material evenly spread in the koji tray 1. By placing the material in the koji tray 1 into the cooking equipment 5 and cooking it at a preset temperature for a certain period of time, not only will the miscellaneous bacteria mixed in the material be killed, thereby avoiding spoilage or off-flavors caused by miscellaneous bacteria during the koji cultivation process, but the original proteins in the material will also be denatured to promote the formation of flavor substances.

[0025] After the material has finished steaming, the tray 1 containing the material is transferred to the drying machine 6 for ventilation and cooling, thus preventing the inoculated koji from becoming inactive due to excessively high material temperature, which would affect the koji-making effect. Once the material temperature in the tray 1 drops to the inoculation temperature, the inoculation and turning device receives the tray 1 from the steaming equipment 5, inoculates the steamed and cooled material with koji, and turns it over. In this embodiment, the inoculation and turning device is an integrated inoculation and turning machine 7, as described above. Figure 2, including a koji seeding device 71 and a koji turning device 72. In the koji seeding device 71, the koji is introduced into the koji tray 1 and inoculated into the material. The koji turning device 72 is longitudinally provided with a koji turning component 721 which turns the material containing the koji. The inoculation and turning of the koji tray 1 by the inoculation and turning integrated machine 7 provided in the embodiment can make the koji more fully and uniformly enter the material to ensure that the concentration of the koji in the material at different positions in the koji tray 1 is basically consistent, thereby avoiding the influence of the uneven concentration of the koji in the material on the stability of the quality of the final koji culture. At the same time, the automatic operation of the inoculation and turning integrated machine 7 greatly saves the labor required for inoculating the koji and turning the material.

[0026] In order to enable the material at different positions in the koji tray 1 to fully contact the koji introduced by the koji seeding device 71 and be turned by the koji turning component 721, in the embodiment, the inoculation and turning integrated machine 7 further comprises a rotating driving mechanism 73 for fixing and driving the koji tray 1 to rotate. The rotating driving mechanism 73 can be a hollow annular structure to facilitate the falling of the material. At the same time, the koji tray 1 in the embodiment is circular in shape, which can further ensure that the material at the outer edge of the koji tray 1 can be inoculated with the koji and turned when the koji tray 1 rotates. At the same time, due to the provision of the rotating driving mechanism 73, the length direction of the koji spraying range of the koji seeding device 71 and the turning range of the koji turning component 721 only needs to cover the radius of the koji tray 1, so that after one rotation of the koji tray 1, the inoculation and turning of the koji to the material at all positions in the koji tray 1 can be completed. In order to enable the koji to be fully mixed in the material in the koji tray 1, in the embodiment, the koji tray 1 can be rotated for a certain number of times or for a certain preset time by the rotating driving mechanism 73 until the koji is fully mixed in all the material at different positions in the koji tray 1, thereby ensuring that the koji culture efficiency in the koji tray 1 is higher and the culture quality is more stable.

[0027] When the koji tray 1 is internally laid with the material to be inoculated with a preset volume, the koji tray 1 is placed below the koji seeding device 71 and the koji turning device 72, and preferably the inoculation of the koji by the koji seeding device 71 and the turning by the koji turning device 72 are simultaneously performed. Of course, the inoculation of the koji by the koji seeding device 71 can be performed on part of the material and then the turning by the koji turning device 72 can be performed, or the inoculation of the koji by the koji seeding device 71 can be performed on all the material and then the turning by the koji turning device 72 can be performed, which is not limited herein. In the embodiment, the koji turning component 721 of the koji turning device 72 comprises a plurality of spiral members 7211 and a spiral member driving device 7212. The spiral members 7211 can longitudinally enter and exit the koji tray 1. The spiral member driving device 7212 drives the spiral members 7211 to pivot, and the spiral member driving device 7212 can be a motor or the like, which has an output shaft connected with the spiral members 7211 and has no particular limitation in structure. For reference Figure 2The turning device 72 further comprises a support rod 722, a plurality of spiral elements 7211 are sequentially arranged below the support rod 722 along the length direction of the support rod 722, and the spiral element driving device 7212 is arranged above the support rod 722. In order to enable the support rod 722 in the inoculation and turning integrated machine 7 to conveniently perform lifting movement while driving the plurality of spiral elements 7211 which are in the process of pivoting rotation, thereby performing the turning operation on the material in the turning disc 1, in the embodiment, the inoculation and turning integrated machine 7 further comprises a rack 74 and a lifting device 75. The inoculation and turning device 71 and the turning device 72 are both connected to the support rod 722, and the support rod 722 is connected to the rack 74. The lifting device 75 is arranged above the rack 74, and the rack 74 is pulled to move up and down along the longitudinal direction by the lifting device 75, so that the inoculation and turning device 71 and the turning device 72 move up and down. The lifting device 75 can be selected from an electric cylinder, an oil cylinder, an air cylinder, a screw nut, or a steel wire rope, and is not limited here.

[0028] In order to enable the inoculum to be uniformly sprayed into the material in the turning disc 1, in the embodiment, the inoculation and turning device 71 comprises a plurality of spray heads 712. At the same time, in order to further realize the integrated and simple design of the inoculation and turning integrated machine 7, in the embodiment, the inoculation and turning device 71 is specifically a conveying pipe 711, and is arranged above the turning disc 1 in a parallel connection form with the support rod 722 of the turning device 7272. Referring to Figure 2 The conveying pipe 711 is connected to the source of the inoculum which is not shown at one end away from the center of the turning disc 1. The surface of the conveying pipe 711 above the radius from the center to the edge of the inside of the turning disc 1 is provided with a plurality of spray heads 712, which are sequentially arranged on the conveying pipe 711, and the spray direction of each spray head 712 is towards the material in the turning disc 1 directly below.

[0029] Since the turning disc 1 is circular in the embodiment, the amount of material close to the center of the turning disc 1 is less than the amount of material close to the outer edge. When the rotating driving mechanism 73 drives the turning disc 1 to rotate around the center, in order to ensure that the inoculation and turning device 71 uniformly sprays the inoculum to the material in the turning disc 1, the inoculum flow of the spray head 712 close to the center of the turning disc 1 is less than the inoculum flow of the spray head 712 close to the periphery of the turning disc 1. In the embodiment, in order to more accurately control the flow of the spray head 712 at different positions on the conveying pipe 711, the inoculation and turning device 71 further comprises a flow meter and a variable frequency pump. In other embodiments, the flow of the spray head 712 can also be controlled by arranging a valve at the spray head 712.

[0030] With the rotation of the curved tray 1 and the inoculum spraying process of the nozzle 712 of the inoculum planter 71 to the material in the curved tray 1, the spiral part 7211 in the turning part 721 is in the first position inside the curved tray 1 from the second position away from the curved tray 1, that is, the spiral part 7211 is in contact with the material, and the material in the curved tray 1 is stirred and turned up by the rotating blade of the spiral part 7211, so that the inoculum sprayed from the nozzle 712 can enter the material and be uniformly mixed with the material. In order to make the material in the curved tray 1 be turned up by the spiral part 7211 as much as possible, the end of the spiral part 7211 towards the inside of the curved tray 1 should extend to the bottom of the curved tray 1 as much as possible. However, considering that the blade of the spiral part 7211 and the curved tray 1 are both made of metal materials, if the two collide or rub, it may cause damage to the equipment, so even if the spiral part 7211 completely reaches the first position, there is still a certain preset distance between the blade of the spiral part 7211 and the bottom surface of the curved tray 1. In order to make the material in the gap between the blade of the spiral part 7211 and the bottom surface of the curved tray 1 also be turned up, and further ensure that the material in the curved tray 1 can be mixed with the inoculum as evenly as possible, in the embodiment, at least part of the spiral part 7211 is provided with a soft head 7213 towards one end of the curved tray 1, referring to Figure 2 , the soft head 7213 of the spiral part 7211 in the first position can be in contact with the bottom surface of the curved tray 1.

[0031] After the inoculum is uniformly mixed into the material in the curved tray 1 by the inoculation and turning device provided in the embodiment, the koji making equipment receives the curved tray 1 from the inoculation and turning device and makes koji.

[0032] In the embodiment, the koji making equipment is a koji making machine 8, referring to Figure 3 , the koji making machine 8 includes a base 81 and a ventilation part 82, wherein the base 81 is used to receive the curved tray 1 removed from the inoculation and turning device, and a plurality of curved trays 1 can be stacked and placed in the base 81; the ventilation part 82 is connected with the base 81, the ventilation part 82 includes an air outlet 822 and an air inlet 821, and a wind path passing through the curved tray 1 is formed between the air outlet 822 and the air inlet 821, so that the incoming airflow is uniformly dispersed in the plurality of curved trays 1 stacked on the base 81, to provide a stable and balanced koji making environment, facilitating the completion of koji making. In addition, the koji making machine 8 provided in the embodiment is also provided with a heat exchanger 83 and a humidifier 84, so as to maintain the stable temperature and humidity environment in the koji making machine 8, and further provide a more suitable koji making environment for the material in the curved tray 1.

[0033] The air outlet 822 is connected with an air outlet pipe 8221, the air outlet pipe 8221 is connected to the side edge of the air outlet 822, and is not opposite to the curved disc 1. The above-mentioned side edge connection scheme can avoid the problem of condensate water falling. Specifically, during koji making, due to heat generated by koji making and moisture carried by the material, the gas entering the material through the air inlet 821 and discharged from the air outlet 822 is usually humid hot gas, and the water in the humid hot gas will condense into water droplets due to sudden temperature drop when discharged, which is easy to fall into the curved disc 1 and affect koji making. In the embodiment, by arranging the air outlet pipe 8221 at the side edge of the air outlet 822 instead of directly above the air outlet 822, the direction of the pipe opening of the air outlet pipe 8221 is offset from the curved disc 1, and the humid hot gas discharged will be cooled at the position of the air outlet pipe 8221 at the side edge, so as to avoid the water droplets generated by condensation from directly vertically falling onto the surface of the curved disc 1, thereby avoiding pollution of the material or destruction of the growth environment of the bacterial population, and further ensuring the stability of koji making. More preferably, a separate heater 115 can be arranged at the air outlet 822 to heat the surface of the air outlet 822 opposite to the curved disc 1, thereby avoiding condensation. The arrangement of the heater 115 is not limited, and preferably a sandwich layer is arranged in the air outlet 822, and a heating device such as an electric heating wire is arranged in the sandwich layer.

[0034] Further, the air outlet pipe 8221 is connected with an air return pipe 85, the air inlet 821 is connected with an air inlet pipe 8211, the air inlet pipe 8211 is connected with the air return pipe 85, and the air return pipe 85 and the air inlet pipe 8211 are connected with a fan 88. Specifically, the air outlet 822, the air outlet pipe 8221, the air return pipe 85, the air inlet pipe 8211 and the air inlet 821 are connected with each other to form a circulating air path, and the air return through the circulating air path can recycle the waste heat and waste humidity of the humid hot gas in the koji making process, thereby effectively reducing the energy consumption. In addition, the air outlet pipe 8221 is connected with an air exhaust pipe 86, and the gas is divided through the air exhaust pipe 86, so that part of the air return carrying waste gas can be discharged, thereby preventing the metabolic products generated in the microbial fermentation process from being excessively accumulated in the air return, so as to inhibit the activity of the target bacterial species. At the same time, the humid hot gas can be quickly discharged through the air exhaust pipe 86, thereby facilitating the temperature and humidity control.

[0035] Further, the air return pipe 85 and the fan 88 are further connected with a fresh air pipe 87. Specifically, the external fresh air is introduced through the fresh air pipe 87, so as to supplement oxygen and maintain the aerobic metabolism of mold, yeast and other microorganisms in the curved disc 1. At the same time, by introducing clean fresh air, the air exhaust pipe 86 for discharging part of the air return can work cooperatively to maintain the balance of the gas composition, thereby further ensuring the stability of the koji making environment.

[0036] Further, the fresh air pipe 87 is provided with a heat exchanger 83, and the external incoming fresh air can be pre-cooled or pre-heated through the heat exchanger 83, and then mixed with the return air in the circulation loop to accurately control the supply air temperature. In addition, the air inlet pipe 8211 is provided with a humidifier 84, which can increase the humidity of the supply air according to the humidity requirement, and the dry fresh air introduced from the outside can be mixed with the return air in the circulation loop to reduce the humidity of the supply air, thereby facilitating the adjustment of the humidity of the supply air in cooperation with the humidifier 84. In the present embodiment, the wet and hot air can be quickly discharged through the exhaust air pipe 86, and the fresh air can be introduced through the fresh air pipe 87, which further cooperates with the heat exchanger 83 and the humidifier 84 to maintain the stable temperature and humidity environment required for koji making, thereby ensuring stable koji making.

[0037] In addition, in order to strengthen temperature control, a temperature sensor 89 is arranged between the humidifier 84 and the air inlet 821. In the present embodiment, the temperature of the air inlet 821 can be monitored by the temperature sensor 89, so that the temperature of the incoming fresh air can be controlled by the heat exchanger 83 according to the koji making temperature requirement, and the supply air temperature entering the air inlet 821 can be controlled to make corresponding adjustment in time according to the koji making environment requirement. Further, a humidity sensor for detecting humidity can be arranged between the humidifier 84 and the air inlet 821 to monitor the humidity of the supply air, so as to monitor and control the humidity of the supply air to maintain the stability of the koji making environment.

[0038] The exhaust air pipe 86 is provided with an exhaust air valve 861, the return air pipe 85 is provided with a return air valve 851, and the fresh air pipe 87 is provided with a fresh air valve 871. In the present embodiment, by adjusting the opening degree of the exhaust air valve 861, the return air valve 851 and the fresh air valve 871, the gas flow of the exhaust air pipe 86, the return air pipe 85 and the fresh air pipe 87 can be adjusted accordingly, thereby adapting to the koji making environment requirement of different microorganisms at different koji making stages to reduce energy consumption and improve koji making efficiency.

[0039] Since the koji material cultivation process includes multiple procedures, the koji tray 1 laid with the material needs to be transported and transferred between different equipment multiple times. In order to reduce the residence time of the koji tray 1 between procedures, in the present embodiment, the koji tray 1 can be transported by the transfer trolley 2 and placed in the preset position of each equipment, for example, the koji tray 1 is handed over between the steaming equipment 5 and the inoculation and koji turning equipment or between the inoculation and koji turning equipment and the koji making equipment. At the same time, by using the transfer trolley 2 provided in the present embodiment, the need for manual transportation can be reduced, especially in the high-temperature and high-humidity koji making workshop, by replacing manual transportation of the koji tray 1 with the transfer trolley 2, the risk of injury to the operator can be effectively reduced. In order to realize the accurate and rapid transportation of the koji tray 1 by the transfer trolley 2, the present embodiment further comprises a control system, which is in communication connection with the transfer trolley 2, and further realizes the full automation and unmanned operation of the brewing system 100 provided in the present embodiment.

[0040] The brewing system 100 provided by the embodiment realizes full-process automation and production operation standardization of the koji-making process by adopting various automatic koji-making equipment and setting a scientific and reasonable koji-making production line. The brewing system 100 can not only avoid human operation differences, thereby ensuring that different batches of koji-making products maintain high and stable quality, but also can make a plurality of automatic equipment in each koji-making link of the brewing system 100 run in parallel, so that the single-batch koji-making period is greatly shortened, thereby meeting the large-scale koji production demand.

[0041] In the embodiment, the brewing system 100 further includes a cleaning device 13, an intermediate koji-turning device 9 and a koji-cutting device. The cleaning device 13 receives the koji tray 1 after koji-making from the transfer trolley 2 and performs cleaning, and after the koji tray 1 is cleaned, it can receive new materials again to prepare for the next batch of koji production.

[0042] When the materials are in the koji-making equipment, the materials need to be in an environment with certain humidity and temperature to complete the growth of the koji. In order to avoid the materials in the koji tray 1 from being overheated or caking in the above environment, thereby affecting the koji-making effect, the intermediate koji-turning device 9 is used in the embodiment to turn the materials during koji-making, so that the materials at different positions in the koji tray 1 can stably complete the koji-making process.

[0043] When the materials in the koji tray 1 complete koji-making, in order to prevent the materials from being mildewed and stabilize the quality of the materials after koji-making, the materials in the koji tray 1 need to be dried. Therefore, the drying device is further included in the embodiment to receive the koji tray 1 and dry the materials after koji-making. The drying device is a dryer 11, which is described with reference to Figure 4 The dryer 11 includes a drying chamber 111 and a drying ventilation part 112. The drying chamber 111 is used to receive at least one koji tray 1, and the drying ventilation part 112 has a drying air inlet 1121 and a drying air outlet 1122 which communicate with the drying chamber 111, and a drying air path passing through the koji tray 1 is formed between the drying air inlet 1121 and the drying air outlet 1122. In the embodiment, the drying chamber 111 can be set as a closed cavity, and a frame door which can be opened and closed is provided to realize the opening and closing of the drying chamber 111. When the koji tray 1 is placed, the drying chamber 111 can be opened, and when the materials in the koji tray 1 are dried, the drying chamber 111 can be closed to further ensure the hot air drying effect.

[0044] A plurality of receiving seats 1111 are arranged along the air path in the drying chamber 111, and a single curved disc 1 is arranged in a single receiving seat 1111. The fixing mode of the curved disc 1 and the receiving seat 1111 is not limited, as long as the curved disc 1 is not affected by the hot air during drying. Specifically, by arranging the receiving seats 1111, the transported curved disc 1 can be quickly placed. By arranging the receiving seats 1111 along the air path, each placed curved disc 1 can have sufficient drying space, thereby effectively ensuring the drying effect.

[0045] The drying air outlet 1122 is arranged at the side edge of the drying chamber 111 and is not opposite to the curved disc 1. Specifically, during the drying process, the hot air introduced through the drying air inlet 1121 carries the water vapor generated by the heating of the material and is discharged. When the humid hot air flows to the drying air outlet 1122 and is discharged, the temperature drops suddenly, and the water vapor in the humid hot air condenses into water and falls down, affecting the drying effect. In the present embodiment, by arranging the drying air outlet 1122 at the side edge of the drying chamber 111, the air outlet position is located at the side edge of the drying chamber 111, preventing the water droplets formed by condensation from falling onto the material of the curved disc 1, and effectively ensuring the drying effect. The drying ventilation part 112 further includes a drying return air pipe 1125, a drying air inlet pipe 1124, a drying fan 113, a cooler 114, a heater 115, a temperature sensor, a drying return air valve 1123, a drying fresh air pipe 117, a drying fresh air valve 1171, and the like, which will be described in detail below.

[0046] The drying air outlet 1122 is connected with the drying return air pipe 1125, and the drying air inlet 1121 is connected with the drying air inlet pipe 1124. The drying return air pipe 1125 and the drying air inlet pipe 1124 are in communication with each other, and the drying fan 113 is arranged between the drying air inlet pipe 1124 and the drying return air pipe 1125. Specifically, the drying fan 113 is driven to drive the air circulation, so that a circulating ventilation path is formed between the drying air inlet pipe 1124, the drying air inlet 1121, the drying chamber 111, the drying air outlet 1122, and the drying return air pipe 1125, and then the drying hot air is circulated and introduced, thereby efficiently drying the material in the drying chamber 111.

[0047] In the present embodiment, the adjustment of the inlet air temperature is not limited, and preferably is performed by the cooler 114 and the heater 115. More specifically, the cooler 114 is further arranged between the drying fan 113 and the drying air outlet 1122, and the heater 115 is further arranged between the cooler 114 and the drying air outlet 1122. Specifically, the wet hot air discharged from the drying air outlet 1122 first enters the cooler 114, and the water in the wet hot air is condensed by the cooler 114, and the condensed water is discharged from a pipeline not shown, so as to ensure the dryness of the circulating air. In addition, the dried air is heated by the heater 115 and then circulated into the drying chamber 111 through the drying air inlet 1121, thereby effectively ensuring the drying efficiency of the circulating ventilation, and effectively reducing the energy consumption by recycling the heated air.

[0048] In order to better perform temperature feedback control, a temperature sensor is arranged in the drying air inlet pipe 1124, and a drying return air valve 1123 is further arranged between the cooler 114 and the drying air outlet 1122. In the present embodiment, the temperature sensor can monitor the temperature of the hot air entering the drying chamber 111 through the drying air inlet 1121, and then the output power of the heater 115 and the opening degree of the drying return air valve 1123 can be adjusted according to the drying requirements. The specific control mode can be adjusted according to different requirements, which is not limited here.

[0049] The drying new air pipe 117 is further connected between the cooler 114 and the heater 115, and the drying new air valve 1171 is arranged in the drying new air pipe 117.

[0050] Specifically, the mixing of the dry new air from the outside and the return air circulating in the pipeline through the drying new air pipe 117 can further ensure the low humidity of the ventilation, thereby ensuring the drying effect; at the same time, the air quality of the ventilation can be maintained by supplementing the new air, so as to prevent the material from being polluted during the ventilation and drying process. At the same time, the opening degree of the drying new air valve 1171 can be controlled to quickly control the amount of new air entering.

[0051] In order to further improve the drying efficiency and prevent the material in the curved disc 1 from being heated and caked during the drying process, the present embodiment further provides a cutting device for cutting the material after being fermented and before being dried. The action of the transfer trolley 2 is controlled to send the curved disc 1 into the cutting device before being sent into the drying device. The cutting device is a cutting machine 10, which cuts and scatters the material after being fermented and before being dried by a cutting knife group, so as to effectively prevent the material from being heated and caked during the drying process and improve the drying efficiency. In order to prevent part of the material in the curved disc 1 from splashing outside the curved disc 1 when being cut and scattered by the cutting machine 10, causing material waste and pollution of the working environment, in the present embodiment, the curved disc 1 is arranged in a curved disc holder 9, and the curved disc holder 9 is arranged in the cutting machine 10. Figure 5The shredding machine 10 comprises a shredding component 101, a cover component 102 moving synchronously with the shredding component 101, and a shredding rotary driving mechanism 106. The shredding component 101 is movable into the curved disc 1 and cuts the material. When the shredding component 101 cuts the material, the cover component 102 covers above the curved disc 1 and is 0-5 mm away from the curved disc 1. Through the above-mentioned embodiments, the part of the splashed material is re-fallen into the curved disc 1, effectively meeting the clean production requirement.

[0052] The shredding component 101 comprises a rotatable shredding knife group arranged in the transverse direction. The material in the curved disc 1 is shredded and scattered by the shredding knife group. Specifically, the material after the koji making and before the drying is shredded and scattered by the shredding knife group, so that the initial bulk density of the material is reduced, thereby effectively preventing the material from being heated and caked during the drying process. At the same time, the specific surface area of the shredded and scattered material is increased, so that the drying efficiency is improved.

[0053] The shredding rotary driving mechanism 106 clamps and drives the curved disc 1 to rotate, so as to increase the shredding efficiency of the shredding knife group. In the present embodiment, the shredding rotary driving mechanism 106 can be a hollow annular structure, so as to facilitate the material to fall down. Further, the shredding component 101 comprises a shredding knife group driving device, the shredding knife group driving device comprises a rotating shaft 103 rotatably arranged in the cover component 102 and a driving member driving the rotating shaft 103 to rotate, and the shredding knife group is arranged on the rotating shaft 103. In the present embodiment, one end of the rotating shaft 103 is rotatably installed in the cover component 102 through a first bearing 1031, and a mounting frame 105 is arranged in the cover component 102, and the other end of the rotating shaft 103 is rotatably installed in the mounting frame 105 through a second bearing 1032. The rotating shaft 103 is arranged in parallel with the shredding rotary driving mechanism 106, and the rotating shaft 103 is driven to rotate inside the cover component 102 by the driving member, thereby driving the shredding knife group arranged on the rotating shaft 103 to rotate.

[0054] The shredding component 101 is arranged in the cover component 102, the cover component 102 is arranged above the shredding rotary driving mechanism 106 in a lifting manner, the cover component 102 is connected with a shredding lifting device 104, and the cover component 102 is pulled to move up and down in the longitudinal direction by the shredding lifting device 104. After the curved disc 1 is fixedly placed on the shredding rotary driving mechanism 106, the cover component 102 is driven to move up and down in the longitudinal direction by the shredding lifting device 104, thereby correspondingly driving the shredding knife group in the cover component 102 to move in and out of the curved disc 1 in the longitudinal direction. In the present embodiment, the shredding lifting device 104 can use an oil cylinder, an electric cylinder, an air cylinder, a screw nut, a steel wire rope, etc. to drive the cover component 102 to move up and down in the longitudinal direction, which is not specifically limited herein.

[0055] Reference Figure 5Further, the cover member 102 is configured to cover the curved disc 1 when the cutting blade group is lowered to shred and disperse the material in the curved disc 1.

[0056] In the embodiment, the cover member 102 is 0-5mm away from the curved disc 1 after covering. By setting a micro-gap of 0-5mm, the sealing of the closed cavity formed after the cover member 102 covers can be effectively guaranteed, and at the same time, part of the splashed material can be allowed to fall back into the curved disc 1, effectively meeting the clean production requirements.

[0057] The curved disc 1 is disc-shaped, and one end of the cutting blade group is arranged close to the inner side wall of the curved disc 1, and the transverse length of the cutting blade group matches the radius of the curved disc 1.

[0058] In the embodiment, the distance between the cutting blade group and the inner side wall of the curved disc 1 is 0-5mm, and the transverse length of the cutting blade group is almost equal to the radius of the curved disc 1, which ensures almost full radial coverage of the material in the curved disc 1 from the center to the edge, so that the cutting processing blind area is basically zero, and the material in the curved disc 1 can be cut and dispersed in the full range when the curved disc 1 rotates. Further, the cutting blade group includes a plurality of cutting blades sleeved on the rotating shaft 103.

[0059] Since the material in different processes has corresponding requirements for the temperature or humidity of the environment, in the embodiment, different devices in the brewing system 100 are placed in different spaces according to the material in different processes. The cleaning device 13 is arranged in the first space 100A, the cooking device 5 is arranged in the second space 100B, the inoculation and koji-making device is arranged in the third space 100C, and the first space 100A, the second space 100B and the third space 100C are independent of each other and are connected to each other through the common space 100D.

[0060] The material after drying has become a koji product, so the material needs to be removed from the curved disc 1. However, at this time, the material is firmly adsorbed in the curved disc 1 due to the generation of a large amount of mycelium. Therefore, the embodiment further provides an out-koji device for conveying the material obtained after koji-making to outside the third space 100C. The out-koji device is a turnover out-koji machine 12, which is described in detail with reference to Figure 6, including a turnover mechanism 121, a scraping mechanism 122, and a hopper 123, wherein the turnover mechanism 121 is used to support the curved tray 1 and can turn over the curved tray 1; the scraping mechanism 122 is arranged opposite to the turned-over curved tray 1 and can scrape the material in the curved tray 1; and the hopper 123 is used to receive the material scraped by the scraping mechanism 122. In the turnover and scraping-out machine 12 provided in the embodiment, the automatic turnover of the curved tray 1 is realized by arranging the turnover mechanism 121. On the one hand, part of the material in the curved tray 1 can directly fall into the hopper 123 arranged below the curved tray 1 by the action of gravity; on the other hand, the scraping mechanism 122 in the turnover and scraping-out machine 12 can be conveniently inserted into the interior of the curved tray 1, so that the material adhered relatively firmly in the curved tray 1 can be scraped. The turnover and scraping-out machine 12 not only turns over the curved tray 1 and scrapes the interior of the curved tray 1 in a fully automatic manner, thereby effectively improving the efficiency of scraping-out and reducing the difficulty of scraping-out, but also can relatively completely remove the material adhered in the curved tray 1, thereby reducing the waste of material caused by the process of scraping-out to a certain extent. In addition, the fully automatic turnover and scraping-out machine 12 reduces the contact between the workers and the dust and microorganisms in the material, thereby eliminating part of the production safety hazards.

[0061] Reference Figure 6 The turnover and scraping-out machine 12 is assembled by a turnover and scraping-out frame 124. The turnover mechanism 121 is located above the turnover and scraping-out frame 124, the hopper 123 is located below the turnover and scraping-out frame 124, and the scraping mechanism 122 is installed on one side surface of the turnover and scraping-out frame 124, and part of the scraping mechanism 122 is located between the turnover mechanism 121 and the hopper 123. In order to enable the curved tray 1 to be scraped-out to enter the turnover mechanism 121 above the turnover and scraping-out frame 124 more conveniently, in the embodiment, the curved tray 1 enters the turnover mechanism 121 from the other side surface of the turnover and scraping-out frame 124 relative to the side surface on which the scraping mechanism 122 is arranged. In order to enable the material in the curved tray 1 to fall into the hopper 123 as much as possible, the area of the material inlet 1231 at the top of the hopper 123 is preferably the same as the cross-sectional area of the turnover and scraping-out frame 124, and is greater than the open surface area of the curved tray 1.

[0062] Compared with the prior art, the material after the fermentation is completed is gradually scraped out from the horizontally placed curved tray 1 by manual scraping. The traditional method not only needs to consume a large amount of manpower, but also there may be part of the material in the curved tray 1 that is difficult to be completely scraped out after the scraping is finished, thereby causing the waste of part of the material. Therefore, in the turnover and scraping-out machine 12 provided in the embodiment, after the curved tray 1 is turned over to a preset angle by the turnover mechanism 121, the opening of the curved tray 1 is inclined toward the ground direction, at this time, the material in the curved tray 1 will have the tendency to fall into the hopper 123 below the curved tray 1 due to the action of its own gravity. Part of the material with weak adsorption between the curved tray 1 can directly fall into the hopper 123, and part of the material only needs to be removed from the interior of the curved tray 1 by relatively light external force.

[0063] In order to make the scraping mechanism 122 more conveniently extend into the interior of the curved disc 1, and prevent the material falling from the curved disc 1 from falling onto the surface of the scraping mechanism 122, thereby causing the contamination or damage of the scraping mechanism 122 to affect its normal use, in the present embodiment, the opening direction of the curved disc 1 after being turned over is not vertically downward, but is inclined downward at an angle with the direction of gravity. In order to make the curved disc 1 after being turned over more stably maintain its inclined angle, so that when the scraping mechanism 122 extends to the interior of the curved disc 1 to scrape the material adhering to the inner surface of the curved disc 1, the curved disc 1 will not easily change its inclined angle or return to the original opening upward state under the action of external force, in the present embodiment, the turning mechanism 121 is provided with a fixing component for fixing the curved disc 1, and the fixing mode is not limited, which can be one of locking, clamping, and engagement. In order to make the energy consumption of the scraping mechanism 122 required when scraping the material in the curved disc 1 smaller, in the present embodiment, the turning angle of the curved disc 1 is 135°, that is, the scraping mechanism 122 vertically enters the interior of the curved disc 1 at an angle of 45° with the inclined horizontal direction to complete the material scraping.

[0064] In the embodiment, the scraping mechanism 122 comprises a linear motion mechanism 1221 and a scraping head 1222. The linear motion mechanism 1221 can move towards or away from the turned-over curved drum 1; the scraping head 1222 is connected to the linear motion mechanism 1221, and when the linear motion mechanism 1221 moves to the position of extending into the curved drum 1, the scraping head 1222 can rotate to scrape the material. The scraping head 1222 comprises a rotating shaft 12222 and a scraper 12221 rotating around the rotating shaft 12222, and the length of the scraper 12221 matches the size of the curved drum 1. The scraping mechanism 122 further comprises a knife feeding driving device 1223 and a scraper driving device 1224. When the curved drum 1 is placed on the turning mechanism 121 and turned 135° by the turning mechanism 121 towards the side of the scraping mechanism 122, the curved drum 1 is fixed with the turning mechanism 121, and the movable direction of the linear motion mechanism 1221 is perpendicular to the opening plane of the curved drum 1. Then the knife feeding driving device 1223 is operated to drive the linear motion mechanism 1221 to extend into the turned-over curved drum 1 until the scraper 12221 provided at the end of the scraping head 1222 connected to the end of the linear motion mechanism 1221 abuts against the material completed in the curved drum 1, and the end of the rotating shaft 12222 substantially coincides with the center position of the curved drum 1. Then the scraper driving device 1224 is started to rotate the scraper 12221 around the rotating shaft 12222, so that the material is gradually scraped from the inside of the curved drum 1 to the hopper 123 below the curved drum 1. In order to enable the scraper 12221 to completely scrape the material from the inside of the curved drum 1, in the embodiment, the inside of the curved drum 1 is circular, and the length of the scraper 12221 towards the side of the curved drum 1 is close to the radius of the circular curved drum 1. As the material is continuously scraped from the inside of the curved drum 1 by the scraper 12221, the turning-out machine 12 continuously pushes the scraper 12221 into the inside of the curved drum 1 by the knife feeding driving device 1223 until the scraper 12221 completely abuts against the inside surface of the curved drum 1, which means that the material in the curved drum 1 is completely scraped.

[0065] In the embodiment, the lower side of the hopper 123 is provided with a material output port 1232. In order to enable the material falling into the hopper 123 to be more concentratedly collected and transferred to other processes or devices, the opening of the material output port 1232 at the lower side of the hopper 123 is small. However, part of the material falling into the hopper 123 cannot be completely broken by the scraper 12221, so it still remains in large blocks, which are difficult to be transferred outside the hopper 123 through the material output port 1232 at the lower side of the hopper 123. Therefore, in the embodiment, a breaking mechanism (not shown in the figure) is provided at the side of the hopper 123 away from the turning mechanism 121, which is used to break the large blocks of material.

[0066] In order to make the scattered material directly used in the fermentation step in the brewing production, a screen (not shown in the figure) is arranged between the lower part of the scattering mechanism in the hopper 123 and the material output port 1232 in the embodiment. After the material in the hopper 123 is scattered by the scattering mechanism, the material will pass through the screen and then be transferred to other equipment or next step outside the hopper 123 through the material output port 1232. In the embodiment, in order to make the material further quantitatively transferred, a quantitative auger 1233 is arranged below the material output port 1232 for receiving the material discharged from the material output port 1232 and transferring the material to other equipment or next step in a quantitative conveying manner.

[0067] In the embodiment, the operation flow of the brewing system is as follows:

[0068] The raw material is first sent by the transfer trolley 2 to the moistening machine 4 in the first space 100A, water is quantitatively added according to the proportion of the raw material and water, and the material is continuously stirred to make the material uniformly absorb water. Then the moistened material is uniformly spread on the entire inner disc surface of the koji drum 1 by the material spreading machine 3 to reach the preset material layer height. Then the koji drum 1 with the spread material is transferred by the transfer trolley 2 to the steaming equipment 5 in the second space 100B, steam heating is performed for steaming to the set time to complete the steaming sterilization. Then the koji drum 1 with the steamed material is transferred by the transfer trolley 2 to the airing machine 6, ventilation cooling is performed to reduce the temperature of the material to the inoculation temperature. The koji drum 1 with the cooled material is transferred by the transfer trolley 2 to the inoculation and koji turning integrated machine 7 in the third space 100C, koji is quantitatively inoculated into the material in the koji drum 1 according to the requirement and stirred uniformly. The koji drum 1 after the inoculation step is transferred by the transfer trolley 2 to the koji making machine 8, koji making culture is performed according to the set temperature and humidity. The koji drum 1 in the koji making machine 8 can be transferred to the intermediate koji turning equipment 9 according to the requirement, the koji in the koji drum 1 is stirred and loosened in the intermediate koji turning equipment 9, and then transferred to the koji making machine 8 in the third space 100C for continuous culture after the koji turning is completed. After the koji making is completed, the transfer trolley 2 transfers the koji drum 1 to the drying machine 11 to dry the material to the required moisture, and the koji drum 1 in the drying machine 11 can be transferred to the cutter 10 according to the requirement, the koji in the koji drum 1 is stirred and loosened in the cutter 10, and then transferred to the drying machine 11 for continuous drying after the koji turning is completed. The dried koji drum 1 is transferred to the koji turning and discharging machine 12, the material in the koji drum 1 is discharged and transported to the koji storage. Finally, the transfer trolley 2 transfers the koji drum 1 after the material is discharged to the cleaning equipment 13 in the first space 100A to clean the koji drum 1, and prepares for the next batch production.

[0069] The above is only a preferred embodiment of the present application, and is not intended to limit the present application.
