Description

Technical Field

[0001] The utility model relates to the field of grain processing, in particular to a grain processing system capable of continuous operation. Background Art

[0002] In the food brewing industry, the main purpose of koji making is to cultivate microorganisms, let them grow and reproduce fully on the koji material, secrete a large number of various enzymes, and provide the material basis for the decomposition, transformation and synthesis of raw materials in the fermentation process. Monascus is a microorganism with specific enzyme activity. The growth of Monascus needs to be carried out in a specific environment. In order to improve the growth of koji in grain, the grain needs to be soaked, steamed and cooled.

[0003] In the prior art, taking the production process of red yeast rice as an example, the current red yeast rice production generally adopts the method of manually pouring grains into a grain soaking tank, draining the water in the grain soaking tank after a period of time, shoveling out the soaked grains, and spreading the grains into a grain steamer for steaming (generally using high-temperature steam for steaming) in a "steam-sensing and steaming" manner. During the period, water is added and stirred 1 to 2 times. After cooking, the grains are shoveled out and transferred to an open space to spread and cool, manually sprinkled with yeast and stirred evenly, and then transferred to a culture room for fermentation and culture. After the culture is completed, the grains are transferred out for drying to finally obtain the product red yeast rice.

[0004] In order to process grain more efficiently and automatically, it is necessary to provide a grain processing system that can operate continuously. In particular, it is necessary to further reduce the floor space of the grain processing system and improve the space utilization efficiency. Summary of the invention

[0005] In view of the above problems, the utility model provides a grain processing system, which can process grains continuously and automatically, occupies less space and improves space utilization efficiency.

[0006] The grain processing system provided by the utility model comprises a raw material inlet, a lifting mechanism, a grain processing part and a plurality of first linear conveying mechanisms. Among them, the lifting mechanism lifts the grain entering from the raw material inlet to the highest position of the grain processing system in the height direction; the plurality of first linear conveying mechanisms are arranged in the horizontal direction, the first first linear conveying mechanism receives the grain sent from the lifting mechanism, the grain outlet of the first linear conveying mechanism of the previous level is arranged correspondingly to the grain inlet of the first linear conveying mechanism of the next level, and the first linear conveying mechanism of the previous level is installed at an inclined or orthogonal angle to the first linear conveying mechanism of the next level; the grain processing part receives and processes the grain from the first linear conveying mechanism.

[0007] By using the lifting mechanism to lift the grain to the highest position and then gradually dropping it to the various grain processing mechanisms of the grain processing part for processing, the various components can be stacked in a certain height direction. Compared with the method of placing them in different areas on the ground, the occupied space can be effectively reduced. The inclined or orthogonal placement of multiple first linear conveying mechanisms can also make more effective use of space, making the overall layout of the grain processing system more compact.

[0008] Optionally, the grain processing system further includes a granary and a quantitative discharging machine, wherein the granary has a granary entrance and a granary exit; the quantitative discharging machine receives grain from the granary exit and delivers it to the lower level in a quantitative manner; the lifting mechanism includes a first lifting mechanism and a second lifting mechanism, wherein the first lifting mechanism lifts the grain from the raw material entrance to above the granary entrance; the second lifting mechanism lifts the grain delivered by the quantitative discharging machine to the highest position. In the above manner, the two-stage lifting mechanism can reduce the length of each lifting mechanism extending in the height direction, thereby reducing the device cost. In addition, in conjunction with the granary and the quantitative discharging machine, the rate at which grain is transported from the raw material entrance into the grain processing system can be more flexible, while still being able to ensure that grain is supplied to the subsequent equipment at a relatively constant rate.

[0009] Optionally, the grain processing system further includes a grain silo conveying auger and a permanent magnetic cylinder. The grain silo conveying auger has a grain silo conveying auger grain inlet and a grain silo conveying auger grain outlet. The grain silo conveying auger grain inlet receives grain from the grain outlet of the first lifting mechanism, and the grain silo conveying auger grain outlet is correspondingly arranged above the grain silo entrance; the permanent magnetic cylinder is arranged below the grain outlet of the first lifting mechanism. By arranging the permanent magnetic cylinder at the above position, part of the iron filings mixed in the raw material can be removed, because the iron filings are removed by magnetic attraction during the falling process, the removal effect of the iron filings is better, and the loss of the raw material itself is small.

[0010] Optionally, the grain processing unit includes a grain soaking machine, a grain steaming machine, a grain cooling and koji seeding machine, and a disc koji making machine. The grain soaking machine is connected to the grain outlet of the first linear conveying mechanism; the grain steaming machine receives the grain soaked in the grain soaking machine and steams it with water vapor; the grain cooling and koji seeding machine spreads the steamed grain received from the grain steaming machine and supplies air to it, and adds koji material to the grain after air supply and cooling; the disc koji making machine receives and stacks the grain with added koji material sent from the grain cooling and koji seeding machine, and provides space for its fermentation. In the above manner, the grain processing unit can continuously and automatically complete the soaking, steaming, cooling, koji seeding and fermentation processes of the grain, thereby improving the automation degree and production efficiency of the grain processing system.

[0011] Optionally, the grain cooling and koji planting machine includes an integrated machine chamber, a conveyor belt, an air cooling mechanism and a koji planting mechanism, wherein the integrated machine chamber has a grain inlet and a grain outlet at both ends along the length direction; the conveyor belt has air holes, which are arranged in the integrated machine chamber along the length direction of the integrated machine chamber, and the conveyor belt transports grain along the conveying direction from the grain inlet to the grain outlet, and along the conveying direction, the setting direction of the conveyor belt is inclined upward to the horizontal direction; the air cooling mechanism supplies air to the conveyor belt in the form of air holes passing through the conveyor belt; the koji planting mechanism is arranged on one side of the air cooling mechanism close to the grain outlet along the conveying direction. In the above manner, by configuring the setting direction of the conveyor belt to be inclined upward to the horizontal direction, on the one hand, the space occupied in the horizontal direction can be effectively reduced, and on the other hand, the contact area between the spread grain and the airflow blown out by the air cooling mechanism is also larger, so that the grain can be quickly cooled. At the same time, after the grain is cooled to a suitable temperature, the koji-seeding mechanism on the side of the air cooling mechanism close to the grain outlet automatically spreads koji onto the grain on the conveyor belt. No manual operation is required throughout the process, saving manpower. In addition, because the conveyor belt is inclined, the koji material can easily diffuse to a lower place due to gravity, which is beneficial to improving the uniformity of the koji material.

[0012] Optionally, the conveyor belt is inclined at an angle of 10-30° to the horizontal direction. When the conveyor belt is inclined at an angle of 10-30° to the horizontal direction, it can prevent the grain from falling off the conveyor belt while allowing the excess koji to penetrate into the grain from high to low.

[0013] Optionally, the disc koji making machine includes a circular culture bed, a wall portion and a distribution machine, the wall portion is arranged around the outer edge of the circular culture bed to form a culture chamber, and the wall portion has an opening portion; the distribution machine has a distribution machine conveyor belt and a distribution head located at the end of the conveying direction of the distribution machine conveyor belt, the distribution head extends into the culture chamber through the opening portion, and the distribution head can move in a radial direction parallel to or inclined to the circular culture bed, so as to arrange the koji matrix transported by the distribution machine conveyor belt at different radial positions of the circular culture bed.

[0014] The material distributing machine is directly used for automatic material distributing. Through the extension and retraction of the material distributing head, the koji matrix can be spread all over the circular culture bed without manual work. On the other hand, the material distributing head is set corresponding to the opening part, and the material distributing head can be extended into the culture room through the opening part to distribute the material, so that the material distributing can be carried out in a relatively closed environment. Compared with the method of directly opening the material distributing in the prior art, the disc koji making machine in this embodiment can effectively isolate the external environment when distributing the material, and avoid the interference of external bacteria on the seed koji culture. Moreover, because the material is extended into the culture room through the opening part instead of spreading the food on the top, the space occupied by the disc koji making machine in the height direction can be further reduced.

[0015] Optionally, the grain processing system further includes a plurality of second linear conveying mechanisms, which are arranged in a horizontal direction, the first second linear conveying mechanism receives grain sent from the grain cooling and koji-making machine, the grain outlet of the second linear conveying mechanism of the previous stage is arranged corresponding to the grain inlet of the second linear conveying mechanism of the next stage, and the second linear conveying mechanism of the previous stage is installed at an inclined or orthogonal angle to the second linear conveying mechanism of the next stage. By arranging the conveying mechanism between the grain cooling and koji-making machine and the disc koji-making machine as a plurality of inclined or orthogonally placed linear conveying mechanisms, the occupied space can be effectively reduced, making the overall layout of the grain processing system more compact.

[0016] Optionally, the first linear conveying mechanism is a conveying auger, and the second linear conveying mechanism is a belt conveyor.

[0017] Optionally, the grain soaking machine includes a plurality of grain soaking tanks, each of which has a grain soaking tank inlet, and the last-stage first linear conveying mechanism has a plurality of first linear conveying mechanism grain outlets, each of which is arranged corresponding to a grain soaking tank inlet. By having different first linear conveying mechanism grain outlets correspond to different grain soaking tanks, the grain can be evenly divided and sent to different grain soaking tanks using a simple device. Moreover, the grain soaking tanks can be used to soak the grain synchronously, so that when some of the grain soaking tanks are closed for soaking, the grain soaking tanks that have already finished soaking can be opened without interfering with each other, and the completely soaked grain therein can be sent to the lower-level device, thereby ensuring the continuous operation of the system.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] <System Composition>

[0027] Figure 1 Schematic diagram of the system composition of the grain processing system 100 in this embodiment. Figure 1 The grain processing system 100 provided in this embodiment includes a raw material inlet 1, a lifting mechanism 2, a plurality of first linear conveying mechanisms 3 and a grain processing unit 4. The lifting mechanism 2 lifts the grain entering from the raw material inlet 1 to the highest position 21 of the grain processing system 100 in the height direction; the plurality of first linear conveying mechanisms 3 are arranged in the horizontal direction, the first first linear conveying mechanism 3 receives the grain sent from the lifting mechanism 2, the grain outlet of the first linear conveying mechanism 3 of the previous level is arranged corresponding to the grain inlet of the first linear conveying mechanism 3 of the next level, and the first linear conveying mechanism 3 of the previous level is installed at an inclined or orthogonal angle to the first linear conveying mechanism 3 of the next level; the grain processing unit 4 receives and processes the grain from the first linear conveying mechanism 3.

[0028] It should be noted that although Figure 1 In the figure, the first linear conveying mechanisms 3 appear to be parallel to each other when viewed from the front, but the "installed at an inclined or orthogonal angle" in this embodiment refers to the top (or bottom) angle, that is, when projected onto the horizontal plane, the first linear conveying mechanisms 3 of the previous and next stages are inclined or orthogonal to each other, so as to improve the compactness of the layout of each component from the top view angle and reduce the space occupied. The "inclined or orthogonal" of the second linear conveying mechanism in the following text is similar, and also refers to the top view angle.

[0029] By using the lifting mechanism 2 to lift the grain to the highest position 21 and then gradually dropping it to the various grain processing mechanisms of the grain processing section 4 for processing, the various components can be stacked to a certain extent in the height direction. Compared with the method of placing various components in different areas on the ground, the occupied space can be effectively reduced. The inclined or orthogonal placement of multiple first linear conveying mechanisms 3 can also make more effective use of space, making the overall layout of the grain processing system 100 more compact.

[0030] Continue to refer Figure 1 In this embodiment, the grain processing section 4 includes a grain soaking machine 41, a grain steaming machine 42, a grain cooling and koji-growing integrated machine 43, and a disc koji-making machine 44. The grain soaking machine 41 is connected to the grain outlet of the first linear conveying mechanism 3; the grain steaming machine 42 receives the grain soaked in the grain soaking machine 41 and steams it with water vapor; the grain cooling and koji-growing integrated machine 43 spreads the steamed grain received from the grain steaming machine 42 and supplies air to it, and adds koji material to the grain after air supply and cooling; the disc koji-making machine 44 receives and stacks the grain with added koji material sent from the grain cooling and koji-growing integrated machine 43, and provides space for its fermentation. In the above manner, the grain processing section 4 can continuously and automatically complete the soaking, steaming, cooling, koji-growing and fermentation processes of the grain, thereby improving the automation degree and production efficiency of the grain processing system 100.

[0031] The following combination Figure 2-Figure 5 The structures of the various components of the grain processing system 100 in this embodiment are introduced respectively.

[0032] <Feeding part>

[0033] Figure 2 Schematic diagram of the structure of the feeding part of the grain processing system 100 in this embodiment. Figure 2The grain processing system 100 also includes a granary 5 and a quantitative discharger 6. The granary 5 has a granary entrance 51 and a granary exit 52. The quantitative discharger 6 receives grain from the granary exit 52 and delivers it to the lower level in a quantitative manner. The lifting mechanism 2 includes a first lifting mechanism 201 and a second lifting mechanism 202. The first lifting mechanism 201 lifts the grain from the raw material entrance 1 to above the granary entrance 51. The second lifting mechanism 202 lifts the grain delivered by the quantitative discharger 6 to the highest position 21. In the above manner, the two-stage lifting mechanism 2 can reduce the length of each lifting mechanism 2 extending in the height direction, thereby reducing the device cost. In addition, in conjunction with the granary 5 and the quantitative discharger 6, the rate at which grain is transported from the raw material entrance 1 into the grain processing system 100 can be more flexible, while still being able to ensure that grain is supplied to the subsequent equipment at a relatively constant rate.

[0034] Figure 2 In the figure, for the convenience of illustration, the position of the second lifting mechanism 202 in the height direction is lowered. In fact, the second lifting mechanism 202 is located above the first lifting mechanism 201 as a whole in the height direction, or is located above the first lifting mechanism 201 in a partially overlapping manner.

[0035] In addition, the grain processing system 100 includes a temporary storage bin 11 connected to the raw material inlet 1, which is used to temporarily store the grain entering from the raw material inlet 1, and use a conveying auger to supply the grain to the grain inlet of the first lifting mechanism 201. When the grain falls into the temporary storage bin 11, dust may be generated. A dust hood 71 is arranged above the temporary storage bin 11, and the dust hood 71 is connected to the dust collector 7, which can generate negative pressure to absorb dust and ensure a clean environment.

[0036] In this embodiment, a granary conveying auger 53 and a permanent magnet cylinder 54 are further arranged between the first lifting mechanism 201 and the granary 5. The granary conveying auger 53 has a granary conveying auger grain inlet 531 and a granary conveying auger grain outlet 532. The granary conveying auger grain inlet 531 receives grain from the grain outlet of the first lifting mechanism 201, and the granary conveying auger grain outlet 532 is correspondingly arranged above the granary entrance 51; the permanent magnet cylinder 54 is arranged below the grain outlet of the first lifting mechanism 201. By arranging the permanent magnet cylinder 54 at the above position, part of the iron filings mixed in the raw material can be removed, because the iron filings are removed by magnetic attraction during the falling process, the removal effect of the iron filings is better, and the loss of the raw material itself is small.

[0037] refer to Figure 2After the grain raw materials enter the temporary storage bin 11 from the raw material inlet 1, they are transported to the first lifting mechanism 201 for the first level of lifting. After being lifted to a position slightly above the granary entrance 51, they are sent out from the grain outlet of the first lifting mechanism 201. The grain sent out from the grain outlet of the first lifting mechanism 201 will naturally fall to the granary conveying auger grain inlet 531 of the granary conveying auger 53 due to gravity. In the process of falling, they will pass through the permanent magnetic cylinder 54, and the iron filings in the grain passing through the permanent magnetic cylinder 54 can be adsorbed and removed by the permanent magnetic cylinder 54.

[0038] Next, the grain silo conveying auger 53 conveys the grains without iron filings to the grain silo 5 for temporary storage through the grain silo entrance 51. The quantitative discharging machine 6 conveys the grains in the grain silo 5 to the second lifting mechanism 202 at a specified flow rate, and the second lifting mechanism 202 can lift the quantitatively conveyed grains to the highest position 21 of the grain processing system 100.

[0039] After the grain is lifted to the highest position 21, it will fall to the first first linear conveying mechanism 3. Multiple first linear conveying mechanisms 3 are used to convey the grain from the highest position 21 to the grain soaking machine 41 of the subsequent stage. The grain sent out by the first linear conveying mechanism 3 of the previous stage will be conveyed to the first linear conveying mechanism 3 of the subsequent stage, and then conveyed backward step by step. The first linear conveying mechanism 3 of the last stage divides the grain and sends it to different grain soaking tanks 410. Specifically, the first linear conveying mechanism 3 of the last stage has multiple first linear conveying mechanism grain outlets 31, which are arranged corresponding to the grain soaking tank inlets 410a of the multiple grain soaking tanks 410 of the grain soaking machine 41 of the subsequent stage.

[0040] <Grain Soaking Machine and Grain Steaming Machine>

[0041] Figure 3 It is a schematic diagram of the structures of the grain soaking machine 41 and the grain steaming machine 42 of the grain processing system 100 provided in this embodiment.

[0042] refer to Figure 3In this embodiment, the grain soaking machine 41 has two or more grain soaking tanks 410. By using multiple grain soaking tanks 410 to soak grain synchronously, when some grain soaking tanks 410 are closed for soaking grain without interfering with each other, the other grain soaking tanks 410 that have finished soaking grain can be opened, and the completely soaked grain therein can be transported to the lower-level device, thereby ensuring the continuous operation of the system. Among them, the grain soaking tank 410 can be a container with a cavity for accommodating water and grains, and a grain soaking tank outlet 410c, a grain soaking tank inlet 410a and a grain soaking tank water inlet 410b are provided on the wall of the grain soaking tank 410. Grains enter the grain soaking tank through the grain soaking tank inlet 410a, and water enters the grain soaking tank through the grain soaking tank water inlet 410b. After soaking in the grain soaking tank for a period of time, the grain enters the grain soaking tank through the grain soaking tank inlet 410a, and after soaking in the water entering through the grain soaking tank water inlet 410b, the soaked water and grain (soaked grain) are discharged from the grain soaking tank outlet 410c, and after being filtered, the grain enters the grain steamer 42, and the water is discharged and flows into the grain soaking water recovery tank.

[0043] The grain steamer 42 has a grain steamer chamber 420, a grain steamer conveying mechanism 421 and a steam supply device 422. The grain steamer chamber 420 can be an airtight chamber that seals the steam inside. After the grain enters the airtight chamber from the grain inlet 420a of the grain steamer chamber, it is continuously steamed under the action of the high-temperature steam in the grain steamer chamber 420.

[0044] The grain steamer conveying mechanism 421 can be any conveying structure that can convey wet grains, such as a conveyor belt, a conveying auger, etc., without limitation. The grain steamer conveying mechanism 421 can convey grains from the left end of the grain steamer chamber 420 to the right end of the grain steamer chamber 420, so that the grains can be conveyed while being steamed at high temperature in the grain steamer chamber 420.

[0045] The steam supply device 422 is connected to the grain steamer chamber 420. The steam supply device 422 can generate a large amount of high-temperature steam, for example, it can be a steam generator. The high-temperature steam generated by the steam supply device 422 is passed into the grain steamer chamber 420 through the steam inlet 423 of the grain steamer chamber 420. Preferably, the steam inlet 423 has one or more extending or distributed in the conveying direction of the grain steamer conveying mechanism 421. By extending the steam inlet 423 in the conveying direction of the grain steamer conveying mechanism 421, or distributing multiple steam inlets 423 in the conveying direction, the grain can be continuously in contact with the high-temperature steam introduced by the steam inlet 423 during the conveying process, so that the steaming and heating of the grain is more uniform.

[0046] The steam inlet 423 can be arranged at any position on the wall of the grain steamer chamber 420. Generally speaking, a position where steam can be sprayed directly toward the grain is more preferred. In some preferred embodiments, in the conveying direction of the grain steamer conveying mechanism 421, the steam inlet 423 is arranged at a position in the grain steamer chamber 420 that is closer to the grain steamer. Figure 3 The position of the middle left end can make contact with the grain entering the grain steamer chamber 420 more quickly, thereby accelerating the steaming rate of the grain in the grain steamer chamber 420.

[0047] Specifically, according to the grain processing system 100 provided in this embodiment, it is only necessary to pass the grain into the grain soaking tank 410 through the grain soaking tank grain inlet 410a, and pass water into the grain soaking tank 410 through the grain soaking tank water inlet 410b. After the grain and water are mixed and soaked in the grain soaking tank 410, the soaked grain is discharged from the grain soaking tank grain outlet 410c to the grain steamer 42. The grain enters the grain steamer chamber 420 from the left end, and the grain is slowly transported under the drive of the grain steamer conveying mechanism 421. To the right end, at the same time, the steam supplied by the steam supply device 422 enters the grain steamer chamber 420 from the steam inlet 423, contacts the grain being transported and heats the grain at high temperature, so that the grain transported to the right end is the grain that has been steamed. Finally, the water generated after the steam is cooled is passed into the condensing heat exchanger 424 from the steam outlet 420b, and is converted into hot water through heat exchange and passed into the hot water tank. The hot water in the hot water tank is used for other production process water in the workshop, thereby realizing the recovery and utilization of thermal energy and saving energy consumption.

[0048] The grain processing system 100 also has a condensing heat exchanger 424, which is arranged on the connecting pipeline between the steam outlet 420b and the hot water tank, so that the mixed fluid of steam and water flowing out of the grain steamer 42 is first heat-exchanged through the condensing heat exchanger 424, and the water after heat exchange flows into the hot water tank for the production of other products in the workshop; in the above manner, the waste heat of the used steam can be utilized to improve the energy utilization efficiency of the grain steamer 42.

[0049] A grain steamer chamber grain outlet 420c is also provided at the right end of the grain steamer chamber 420, and the grain that has been steamed and has residual heat will be sent out from the grain steamer chamber grain outlet 420c and transported to the lower-level grain cooling and koji-growing integrated machine 43.

[0050] <Grain cooling and koji seeding machine>

[0051] Figure 4 1 is a schematic diagram of the structure of the grain cooling and koji seeding integrated machine 43 of the grain processing system 100 of this embodiment. Figure 4 In this embodiment, the grain cooling and koji-seeding integrated machine 43 includes an integrated machine chamber 430, a conveyor belt 431, an air cooling mechanism 432 and a koji-seeding mechanism 433.

[0052] Among them, the integrated machine chamber 430 has a grain inlet 430a and a grain outlet 430b at both ends along the length direction, the conveyor belt 431 has ventilation holes, and the conveyor belt 431 is arranged in the integrated machine chamber 430 along the length direction of the integrated machine chamber 430. The conveyor belt 431 transports grain along the conveying direction from the grain inlet 430a to the grain outlet 430b. Along the conveying direction, the setting direction of the conveyor belt 431 is inclined to the horizontal direction (the left and right directions in the figure are horizontal directions) and upward; the air cooling mechanism 432 supplies air to the conveyor belt 431 in the form of ventilation holes passing through the conveyor belt 431; the koji planting mechanism 433 is arranged on the side of the air cooling mechanism 432 close to the grain outlet 430b along the conveying direction.

[0053] By configuring the setting direction of the conveyor belt 431 to be inclined upward relative to the horizontal direction, on the one hand, the space occupied by the all-in-one machine in the horizontal plane projection direction can be effectively reduced, and on the other hand, the contact area between the spread grain and the airflow blown out by the air cooling mechanism 432 is also larger, which can achieve rapid cooling of the grain. At the same time, after the grain is cooled to a suitable temperature, the koji-seeding mechanism 433 on the side of the air cooling mechanism 432 close to the grain outlet 430b automatically spreads koji to the grain on the conveyor belt 431, and no manual operation is required throughout the process, which saves manpower. In addition, because the conveyor belt 431 is inclined, the koji material is easily diffused to a lower place due to gravity, which is conducive to improving the uniformity of the koji material.

[0054] The conveyor belt 431 is inclined at an angle of 10-30° to the horizontal direction. When the conveyor belt 431 is inclined at an angle of 10-30° to the horizontal direction, it is possible to prevent the grain from falling off the conveyor belt 431 while allowing the excess koji to penetrate into the grain from high to low.

[0055] The koji-seeding mechanism 433 is arranged on one side of the air cooling mechanism 432 close to the grain outlet 430b along the conveying direction. The structure of the koji-seeding mechanism 433 is not limited herein. For example, the koji-seeding mechanism 433 may include a nozzle to achieve koji-seeding by spraying liquid koji or koji powder toward the conveyor belt 431, or in other embodiments, the koji-seeding mechanism 433 may also be a dropper to continuously produce liquid carrying fine bacteria on the surface of the conveyor belt 431.

[0056] Preferably, liquid koji is stored in the koji-seeding mechanism 433. Since the conveyor belt 431 is inclined and the koji-seeding mechanism 433 is located on the side closer to the grain outlet 430b, after the liquid koji is sprayed, it will diffuse downward into the grain that has not been seeded with koji due to the inclination of the conveyor belt 431, thereby ensuring uniform koji seeding and making full use of the liquid koji.

[0057] <Disc Koji Making Machine>

[0058] Figure 5It is a schematic diagram of the structure of the disc koji making machine 44 in the grain processing system 100 provided in this embodiment.

[0059] The disc koji making machine 44 includes a circular culture bed 440, a wall portion 441 and a distribution machine 442. The wall portion 441 is arranged around the outer edge of the circular culture bed 440 to form a culture chamber, and the wall portion 441 has an opening portion 441a; the distribution machine 442 has a distribution machine conveyor belt 442a and a distribution head 442b located at the end of the conveying direction of the distribution machine conveyor belt 442a, and the distribution head 442b extends into the culture chamber through the opening portion 441a. The distribution head 442b can move in a radial direction parallel to or inclined to the circular culture bed 440, so as to arrange the koji matrix transported via the distribution machine conveyor belt 442a at different radial positions of the circular culture bed 440.

[0060] In this embodiment, the material distributing machine 442 is directly used for automatic material distributing. By extending and retracting the material distributing head 442b, the circular culture bed 440 can be covered with the koji matrix without manual work. On the other hand, the material distributing head 442b is set corresponding to the opening 441a, and the material distributing head 442b can be extended into the culture chamber through the opening 441a to distribute the material, so that the material distributing can be carried out in a relatively closed environment. Compared with the method of directly opening the material distributing in the prior art, the disc koji making machine 44 in this embodiment can effectively isolate the external environment when distributing the material, and avoid the interference of external bacteria on the seed koji culture. Moreover, because the material is extended into the culture chamber through the opening 441a instead of spreading the food on the top, the space occupied by the disc koji making machine 44 in the height direction can be further reduced.

[0061] <Second linear conveying mechanism>

[0062] Similar to the first linear conveying mechanism 3, multiple second linear conveying mechanisms (not shown) can also be arranged between the grain soaking machine 41 and the grain steaming machine 42, or between the grain steaming machine 42 and the grain cooling and koji-making machine 43, or between the grain cooling and koji-making machine 43 and the disc koji-making machine 44.

[0063] In this embodiment, a plurality of second linear conveying mechanisms are further provided between the grain cooling and koji-growing integrated machine 43 and the disc koji-making machine 44. The plurality of second linear conveying mechanisms are arranged in a horizontal direction, and the first second linear conveying mechanism receives the grain sent from the grain cooling and koji-growing integrated machine 43. The grain outlet of the second linear conveying mechanism of the previous stage is arranged corresponding to the grain inlet of the second linear conveying mechanism of the next stage, and the second linear conveying mechanism of the previous stage is installed at an inclined or orthogonal angle to the second linear conveying mechanism of the next stage. By arranging the conveying mechanisms between the components as a plurality of inclined or orthogonally placed linear conveying mechanisms, the occupied space can be effectively reduced, making the overall layout of the grain processing system 100 more compact.

[0064] In this embodiment, the first linear conveying mechanism 3 is a conveying auger, and the second linear conveying mechanism is a belt conveyor. In other embodiments, the first linear conveying mechanism 3 and the second linear conveying mechanism can be reasonably adjusted according to actual needs, and the utility model does not limit this.

[0065] Through the above methods, the grain processing system 100 provided in this embodiment has a smaller footprint and space occupancy, a more compact overall layout, and can implement grain processing more continuously and automatically, thereby improving production efficiency.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
