Description

Technical Field

[0001] This invention relates to the field of corn stalk preparation of microbial culture medium, specifically a combined unit for crushing fresh corn stalks and preparing microbial culture medium. Background Technology

[0002] Fresh corn stalks are rich in cellulose, hemicellulose and lignin, making them an ideal raw material for producing edible fungi culture media. As the edible fungi industry develops towards large-scale and industrialized production, the demand for high-quality culture media is increasing. Currently, the preparation of fresh corn stalk culture media mainly adopts a simple series unit mode combining a crusher, a conveyor belt and a mixer. This mode is designed for the characteristics of dry stalks and cannot adapt to the special physical properties of fresh corn stalks, such as high moisture content, high fiber toughness and high viscosity. Traditional series units are composed of multiple devices. Fresh corn stalks are fluffy and sticky after being crushed, making them prone to bridging or clogging in conveyor belts, pipes and hoppers. This requires frequent shutdowns for cleaning. The crusher and mixer are independent devices, which means that one device has to wait for another, resulting in low production efficiency and failing to meet the needs of large-scale production.

[0003] Patent CN104119133B discloses a king oyster mushroom culture medium made from corn stalks and its preparation method. The patent realizes the use of maltose residue as raw material, providing a new way to process maltose residue. It contains crude protein and crude fiber, which, when combined with other raw materials, can provide a guarantee for the growth of king oyster mushrooms.

[0004] The aforementioned patent involves the following steps: Step 1: Moistening dried chicken manure with water until the moisture content reaches 45-50%, then adding EM-bacterial solution and sealing for fermentation for 20-24 days; Step 2: Adding glucose and calcium lignin sulfonate to 12-14 times the amount of water and stirring until dissolved; Step 3: Sun-drying corn stalks and mugwort leaves for 20-22 hours, then crushing them and mixing them with sawdust, rice bran, maltose residue, gypsum powder, soybean powder, river mud, charcoal powder, and the materials obtained in Steps 1 and 2, adding water and stirring until the moisture content reaches 67-68%; Step 4: Adding spinach seeds... Add 5-6 times the amount of water to hops, jujube flowers, atractylodes macrocephala, and scutellaria baicalensis and simmer over low heat for 40-50 minutes. Filter to remove residue, simmer over low heat to make a paste. Mix the resulting paste with the raw materials not used in the above process. Step 5: Place a round tube in a polyethylene plastic bag, fill the gap between the round tube and the polyethylene plastic bag with the material obtained in step 3, then put the material obtained in step 4 into the round tube, then pull out the round tube, tie the opening, and sterilize with 100℃ steam at normal pressure to obtain the culture medium. There is room for optimization in the continuity of corn stalk crushing and preparation.

[0023] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 A combined unit for crushing fresh corn stalks and preparing microbial culture medium includes a fixed base 1 and a housing 2. The housing 2 is located on the upper side of the outer wall of the fixed base 1. The housing 2 consists of a crushing chamber 3, a transition chamber 4 and a preparation chamber 5. The preparation chamber 5 is located on the upper side of the outer wall of the fixed base 1. The transition chamber 4 is located on the upper side of the outer wall of the preparation chamber 5. The crushing chamber 3 is located on the upper side of the outer wall of the transition chamber 4. A motor 6 is located in the middle of the inner wall of the fixed base 1. A rotating shaft 7 is located inside the housing 2. The rotating shaft 7 passes through the crushing chamber 3, the transition chamber 4 and the preparation chamber 5. The rotating shaft 7 is connected to the output end of the motor 6. A gearbox 8 is located in the middle of the inner wall of the transition chamber 4. The rotating shaft 7 inside the transition chamber 4 is connected to the gearbox 8. A controller 9 is located on the front side of the outer wall of the fixed base 1. The motor 6 is connected to the controller 9 through a signal line. Inside the crushing chamber 3, a rotating shaft 7 is fixedly connected to a turntable 10 and a turntable 2 11. The turntable 10 and the turntable 2 11 are connected by a crushing shaft 12. A crushing block 13 is provided on the outer wall of the crushing shaft 12. A throwing plate 14 is provided on the upper side of the outer wall of the turntable 10. A stirring shaft 21 is provided in the middle of the inner wall of the mixing chamber 5. The stirring shaft 21 is fitted onto the rotating shaft 7. The upper end of the stirring shaft 21 is connected to the gearbox 8. The mixing chamber 5 is provided with a dispersing blade 22 and a propeller blade 23. The propeller blade 23 is located below the dispersing blade 22. There are 4 sets of dispersing blades 22. Both the dispersing blades 22 and the propeller blade 23 are connected to the stirring shaft 21. An adding chamber 24 is provided on the upper side of the inner wall of the mixing chamber 5. The adding chamber 24 is annular. Nozzles 25 are evenly distributed on the inner annular surface of the adding chamber 24. The transmission 8 consists of a sun gear 35, a planet carrier 36, and an internal gear ring 37. The sun gear 35 is located in the middle of the inner wall of the transition cavity 4. The sun gear 35 is fixedly connected to the rotating shaft 7. The planet carrier 36 is located on the lower side of the outer wall of the sun gear 35. The planet carrier 36 is mounted on the rotating shaft 7. The planet carrier 36 is fixedly connected to the stirring shaft 21. The internal gear ring 37 is located on the inner wall of the transition cavity 4. Furthermore, after the staff puts the fresh corn stalks into the crushing chamber 3, the controller 9 controls the motor 6 to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the turntables 10 and 11 to rotate synchronously at a speed of 3500 rpm. After the fresh corn stalks enter the crushing chamber 3, the throwing plate 14 follows the high-speed rotation of the turntable 10, causing the falling stalks to be evenly thrown to the inner wall of the crushing chamber 3. The rotation of the turntables 10 and 11 drives the crushing shaft 12 and the crushing blocks 13 to rotate together. The crushing blocks 13 impact, shear, and grind the stalks, crushing them into fine fibers. During the crushing process, the coarse material is thrown into the crushing chamber 3 under the action of centrifugal force to continue crushing until the particle size meets the requirements. The crushed material that meets the particle size requirements falls naturally under the action of gravity, passes through the screen plate 15 and enters the transition chamber 4, and then enters the mixing chamber 5. The coarse material that does not meet the particle size requirements is screened by the screen plate 15 and continues to be crushed in the crushing chamber 3 until... After the particle size meets the requirements, the material falls and the sun gear 35 rotates together with the rotating shaft 7. The sun gear 35 drives the planetary gears on the planetary carrier 36 to rotate. The planetary gears are subjected to the reaction force of the internal gear ring 37 and revolve around the axis of the sun gear 35 while rotating. The revolution of the planetary gears drives the planetary carrier 36 to rotate. Due to the fixation of the internal gear ring 37 and the high speed input of the sun gear 35, the rotation speed of the planetary carrier 36 is much lower than that of the sun gear 35, so the stirring shaft 21, which is fixedly connected to the planetary carrier 36, rotates at a low speed together with the planetary carrier 36. The stirring shaft 21 drives the dispersing blade 22 and the propeller blade 23 to rotate at a speed of 120 rpm. The material falling into the mixing chamber 5 is evenly mixed under the action of the dispersing blade 22 and the propeller blade 23. During the material mixing process, the controller 9 can add lime, gypsum and wheat bran through the auxiliary material addition port 52 and add inoculum and water through the addition chamber 24 to complete the preparation of the culture medium.

[0024] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 A combined unit for crushing fresh corn stalks and preparing microbial culture medium, wherein a rotating shaft 7 inside the crushing chamber 3 is fixedly connected to a turntable 10 and a turntable 2 11, and the turntable 10 and the turntable 2 11 are connected by a crushing shaft 12, and a crushing block 13 is provided on the outer wall of the crushing shaft 12, and a throwing plate 14 is provided on the upper side of the outer wall of the turntable 10. A screen plate 15 is provided on the upper side of the outer wall of the gearbox 8. The screen plate 15 is fitted on the rotating shaft 7. A scraper 16 is provided on the lower side of the outer wall of the turntable 11. The lower surface of the scraper 16 contacts the screen plate 15. A reverse gear ring 17 is provided on the lower side of the outer wall of the screen plate 15. An internal gear ring 18 is provided on the inner wall of the transition cavity 4. A gear 19 is provided between the reverse gear ring 17 and the internal gear ring 18. The gear 19 is connected to the screen plate 15 through a pin. A replacement port 20 is provided on the left side of the outer wall of the transition cavity 4. Furthermore, after the straw enters the crushing chamber 3, it is broken into small pieces by the crushing blocks 13. Under the action of the screen plate 15, the material that meets the requirements falls into the transition chamber 4, while the coarse material is intercepted by the screen plate 15. The turntable 11 rotates at high speed under the drive of the rotating shaft 7, causing the scraper 16 fixed below the turntable 11 to rotate synchronously. The scraper 16 contacts the screen plate 15 and scrapes off the coarse material on the screen plate 15 during the rotation. At the same time, the reverse gear ring 17 meshes with the internal gear ring 18 fixed on the inner wall of the transition chamber 4 through the gear 19. Since the internal gear ring 18 on the lower side of the screen plate 15 is fixed, the gear 19 rotates on its own axis while revolving around the central axis, driving the internal gear ring 18 to rotate. The sieve plate 15 rotates in the opposite direction to the scraper 16 at a speed of 85 rpm, which prevents high moisture content straw fibers from adhering to the upper surface of the sieve plate 15 and causing blockage. When straw fibers begin to adhere to the surface of the sieve plate 15, the newly adhered straw fibers are immediately scraped off by the action of the forward high-speed rotating scraper 16 and the reverse low-speed rotating sieve plate 15. The scraped straw fibers return to the crushing chamber 3 and are further crushed by the crushing block 13 until the particle size meets the standard and then pass through the sieve plate 15. When it is necessary to produce culture media with different particle size requirements, the operator can replace the sieve plate 15 by opening the replacement port 20 and stopping the machine.

[0025] Example 3: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 A combined unit for crushing fresh corn stalks and preparing microbial culture medium includes a fixed base 1 and a housing 2.

The rotating shaft 7 inside the transition chamber 4 is connected to the gearbox 8. A controller 9 is located on the front side of the outer wall of the fixed base 1. The motor 6 is connected to the controller 9 through a signal line. A stirring shaft 21 is provided in the middle of the inner wall of the mixing chamber 5. The stirring shaft 21 is fitted onto the rotating shaft 7. The upper end of the stirring shaft 21 is connected to the gearbox 8. The mixing chamber 5 is provided with a dispersing blade 22 and a propeller blade 23. The propeller blade 23 is located below the dispersing blade 22. There are 4 sets of dispersing blades 22. Both the dispersing blades 22 and the propeller blade 23 are connected to the stirring shaft 21. An adding chamber 24 is provided on the upper side of the inner wall of the mixing chamber 5. The adding chamber 24 is annular. Nozzles 25 are evenly distributed on the inner annular surface of the adding chamber 24. The propeller blade 23 is composed of an inner spiral band 38 and an outer spiral band 39, which are connected to the stirring shaft 21 via a support rod 40. A culture chamber 41 is provided on the left side of the outer wall of the shell 2. A delivery pump 42 is provided on the upper side of the outer wall of the culture chamber 41. A buffer chamber 43 is provided at the connection between the delivery pump 42 and the culture chamber 41. A weight sensor 44 is provided on the inner wall of the buffer chamber 43. A metering valve 45 is provided at the connection between the buffer chamber 43 and the delivery pump 42 and the culture chamber 41. The output end of the delivery pump 42 is connected to the addition chamber 24 through a connecting pipe. A motor 46 is provided on the left side of the outer wall of the delivery pump 42. The delivery pump 42 is connected to the motor 46 through a connecting rod. The weight sensor 44, the metering valve 45 and the motor 46 are respectively connected to the controller 9 through signal lines. A material addition port 52 is provided at the lower part of the inner wall of the crushing chamber 3. An interface 53 is provided on the side of the material addition port 52 away from the crushing chamber 3. An addition valve 54 is provided at the connection between the interface 53 and the crushing chamber 3. The addition valve 54 is connected to the controller 9 through a signal line. Furthermore, according to the preset formula, the controller 9 controls the metering valve 45 to open. Driven by the motor 46, the conveying pump 42 draws the inoculum stored in the inoculum box 41 into the buffer chamber 43. The weight sensor 44 in the buffer chamber 43 collects the weight of the inoculum in real time. After reaching the set value, the controller 9 controls the metering valve 45, which is connected to the buffer chamber 43, the inoculum box 41, and the conveying pump 42, to close. During the crushing process of fresh corn stalks entering the crushing chamber 3, the controller 9 opens the adding valve 54 to connect the auxiliary material adding device to the interface 53. The auxiliary material adding device consists of a box for storing auxiliary materials and a conveying device. The system consists of a power booster pump and a metering unit for calculating the conveying capacity. Workers add solid auxiliary materials such as lime, gypsum, and wheat bran to the lower part of the crushing chamber 3 through the auxiliary material addition port 52. The auxiliary materials and straw at a temperature of 60-70℃ undergo preliminary mixing within the crushing chamber 3. The residual heat generated during the crushing process dissolves the soluble components in the auxiliary materials, while simultaneously ensuring full contact between the auxiliary materials and the straw fibers, preventing clumping during subsequent mixing. The crushed material, meeting the particle size requirements, passes through the sieve plate 15 under gravity and enters the upper part of the mixing chamber 5. There, the material is further dispersed by the high-speed impact and agitation of the dispersing blades 22, resulting in a fluffy texture. Straw fibers are dispersed into a uniform mist-like suspension, filling the upper space of the mixing chamber 5. Each straw fiber particle in the suspension is independently dispersed, allowing the inoculum to adhere evenly. When the material forms a stable suspension, the controller 9 controls the motor 46 to drive the delivery pump 42, and simultaneously opens the metering valve 45 connecting the delivery pump 42 and the buffer chamber 43. Under the action of the delivery pump 42, the inoculum liquid in the buffer chamber 43 enters the annular addition chamber 24, and then the inoculum liquid is atomized into tiny droplets of 50-100μm by uniformly distributed nozzles 25, which are tilted downwards at a 30° angle. The nozzle 25 sprays the inoculum solution into the suspension flow, so that the inoculum and straw fiber are evenly mixed. Then, under the action of gravity, it continues to fall. After the inoculated material falls to the propeller blade 23, the inner spiral belt 38 lifts the bottom material upward, and the outer spiral belt 39 pushes the upper material downward, forming a continuous up-and-down circulation flow, so that the inoculum, auxiliary materials and straw fiber are evenly mixed in a short time. During the mixing process, the moisture content sensor 26, pH sensor 27 and temperature sensor 28 detect the culture medium parameters in real time. The controller 9 automatically adjusts the amount of water and auxiliary materials added to ensure that the prepared culture medium meets the requirements.

After the materials enter the mixing chamber 5 and begin mixing, three sets of circumferentially distributed moisture content sensors 26, pH sensors 27, and temperature sensors 28 detect the moisture content, pH, and temperature of the culture medium. The controller 9 compares the real-time detected parameters with the target parameters. If the moisture content is lower than the target value, the controller 9 automatically increases the amount of water added; conversely, it decreases the amount of water added. If the pH value is lower than the target value, the controller 9 automatically opens the addition valve 54 to increase the amount of lime added; conversely, it decreases the amount of lime added. If the temperature is higher than 40℃, the controller 9 controls the motor 51 to reduce the rotation speed of the rotating shaft 50 and the baffle 49, thereby reducing the amount of material entering the crushing chamber 3 from the feed hopper 48 through the feed inlet 47, and delaying the process. During the extended mixing and heat dissipation time, the feed pump 42 is controlled to reduce the amount of inoculum added. Normal operation is resumed after the temperature drops to a suitable range. If the mixing speed of the materials in the mixing chamber 5 is too fast and the material is insufficient, the speed of motor 51 is adjusted to increase the opening of baffle 49 to ensure that the feeding speed matches the mixing speed. When all detection parameters are stable within the target range for 30 seconds, the controller 9 controls motor 2 32 to drive the rotating shaft 2 31 to rotate, opening the discharge gate 30 by 60%. At the same time, the controller controls motor 34 to drive the conveyor 33 to operate at the set speed, discharging the finished culture medium in the mixing chamber 5 evenly and continuously at a certain rate. During the discharge process, the moisture content sensor 26, pH sensor 27, and temperature sensor 28 continuously detect the culture medium parameters. If fluctuations occur, the discharge speed and the amount of raw materials added are immediately adjusted to ensure stable discharge quality. After the discharge is completed, the controller 9 controls the discharge gate 30 to close.

[0027] Example 5: Please refer to Figure 1 , Figure 2 and Figure 8 A combined unit for crushing fresh corn stalks and preparing microbial culture medium, wherein a rotating shaft 7 inside the crushing chamber 3 is fixedly connected to a turntable 10 and a turntable 2 11, and the turntable 10 and the turntable 2 11 are connected by a crushing shaft 12, and a crushing block 13 is provided on the outer wall of the crushing shaft 12, and a throwing plate 14 is provided on the upper side of the outer wall of the turntable 10. A feed inlet 47 is provided on the upper side of the outer wall of the crushing chamber 3. A feed hopper 48 is provided on the upper side of the outer wall of the feed inlet 47. A baffle 49 is provided in the middle of the inner wall of the feed hopper 48. The baffle 49 is connected to the feed hopper 48 through a rotating shaft 3 50. A motor 51 is provided on the left side of the outer wall of the feed hopper 48. The rotating shaft 3 50 is connected to the output end of the motor 51. The motor 51 is connected to the controller 9 through a signal line. Furthermore, during the straw conveying process, the controller 9 automatically adjusts the speed of the motor 51 based on the amount of material in the mixing chamber 5 and the mixing progress detected by the moisture content sensor 26, pH sensor 27, and temperature sensor 28. The motor 51 drives the baffle 49 to rotate through the rotating shaft 3 50, thereby adjusting the opening of the feed inlet 47. This avoids relying on the experience of the staff to adjust the straw feeding speed. Feeding too fast will cause the crushing chamber 3 to be blocked and the equipment to be overloaded, while feeding too slow will reduce production efficiency. After the straw enters the crushing chamber 3, it is evenly thrown to the inner wall of the crushing chamber 3 by the throwing plate 14 that rotates synchronously on the upper side of the turntable 10. This avoids the material from concentrating in the central area of ​​the crushing chamber 3, ensuring that the crushed blocks 13 are evenly stressed, avoiding severe local wear of the equipment, and extending the service life of the equipment.

[0028] Working principle: The operator inputs the target culture medium parameters into the controller 9. The controller 9 automatically calculates the addition ratio of straw, auxiliary materials, water and inoculum according to the preset formula. Then, the operator puts the straw into the feed hopper 48. The motor 51 drives the rotating shaft 3 50 and adjusts the opening of the baffle 49 to send the straw from the feed port 47 into the crushing chamber 3. The throwing plate 14 throws the straw evenly to the inner wall of the crushing chamber 3. The motor 6 drives the rotating shaft 7 to rotate. The turntable 10 and the turntable 2 11 rotate synchronously with the rotating shaft 7. The crushing block 13 crushes the straw and adds the corresponding auxiliary materials through the auxiliary material addition port 52 for preliminary pre-mixing. The scraper 16 fixed below the turntable 2 11 rotates synchronously with the turntable 2 11. At the same time, under the action of the reverse gear ring 17, the internal gear ring 18 and the gear 19, the screen plate 15 rotates in the opposite direction at a low speed relative to the scraper 16. The scraper 16 contacts the screen plate 15 and scrapes off the coarse material trapped on the screen plate 15 during the rotation process to prevent the screen plate 15 from becoming blocked. Materials that meet the particle size requirements pass through the sieve plate 15, through the transition chamber 4, and into the mixing chamber 5. The gearbox 8 drives the stirring shaft 21 to rotate at a low speed, causing the dispersing blades 22 to disperse the materials and form a suspension. The conveying pump 42 delivers the inoculum liquid to the addition chamber 24, which is sprayed out by the nozzle 25 and mixed with the suspension. The inoculum and materials are evenly mixed. Then, the inner spiral belt 38 lifts the bottom material upward, and the outer spiral belt 39 pushes the upper material downward, so that the inoculum, auxiliary materials, and straw fiber are evenly mixed. During the mixing process, the moisture content sensor 26, pH sensor 27 and temperature sensor 28 detect the parameters of the culture medium in real time. The controller 9 automatically adjusts the amount of straw, water, auxiliary materials and inoculum added. When the parameters of the culture medium are stable within the target range for 30 seconds, the controller 9 controls the motor 2 32 to drive the rotating shaft 2 31 to rotate, opening the discharge gate 30. The conveyor 33 discharges the material evenly and continuously at a certain rate. After the finished culture medium is discharged, the controller 9 controls the discharge gate 30 to close.
