Description

Technical Field

[0001] This invention relates to the field of fermentation production equipment technology, and in particular to an apparatus and method for producing soybean kinase by fermenting wet soybean residue. Background Technology

[0002] Wet soybean residue, rich in protein, carbohydrates, and cellulose, provides ample carbon and nitrogen sources for Bacillus natto, promoting its growth and nattokinase secretion, making it an ideal raw material for the production of nattokinase. However, as a byproduct of soy milk or tofu production, wet soybean residue has a moisture content of approximately 80%-85%, which directly leads to the formation of dense clumps between residue particles during steam sterilization. The center of these clumps has a low temperature due to thermal resistance, failing to reach the effective sterilization threshold. Simultaneously, water-soluble polysaccharides in the residue form a viscoelastic gel network under high moisture conditions, causing a surge in material viscosity and severely hindering oxygen diffusion. This results in a sharp drop in oxygen concentration deep within the fermentation bed, causing abnormal pH fluctuations and enzyme activity loss. Furthermore, the viscous material easily caking during ventilation, blocking air vents and creating anaerobic dead zones, further inhibiting bacterial activity. The synergistic effect of high moisture and viscosity ultimately creates a vicious cycle: clumping leads to incomplete sterilization and induces contamination; viscosity hinders oxygen mass transfer and inhibits metabolism; and ineffective turning and ventilation exacerbate uneven material distribution. All three factors contribute to a decrease in fermentation efficiency. Therefore, improvements are necessary. Summary of the Invention

[0013] As a further aspect of the present invention: the apparatus for producing soybean kinase by fermentation of wet soybean residue further includes a shell, the inner wall of which is fixedly connected with a plurality of partition plates, which divide the inner cavity of the shell into a plurality of equipment compartments arranged vertically. The pretreatment mechanism, sterilization mechanism, fermentation mechanism and drying mechanism are respectively arranged in each equipment compartment from top to bottom. The bottom of the discharge platform is connected to the input end of the sterilization mechanism through a crushing discharge pipe, the output end of the sterilization mechanism is connected to the fermentation mechanism through a connecting pipe, and the output end of the fermentation mechanism is connected to the input end of the drying mechanism through a fermentation discharge pipe.

[0014] A method for producing soybean kinase by fermenting wet soybean residue includes the following steps: Step 1: The wet soybean residue is crushed using a pretreatment device; Step 2: After the soybean residue has been crushed, it is sent to a sterilization treatment facility for sterilization, and then inoculated with fermentation bacteria; Step 3: Send the soybean residue inoculated with the bacteria into the fermentation facility for fermentation; Step 4: The fermentation unit receives the soybean residue via a conveyor belt.

Simultaneously, the invention incorporates a turning unit. A turning guide rail drives the turning rollers of the turning frame to move along the length of the conveyor belt, agitating the material and preventing the soybean residue from clumping. A directional motor drives the rotation of the turning rollers, thereby adjusting the position and orientation of the turning rollers and controlling the agitation depth. Furthermore, the rotation of the turning rollers drives the push plate to rotate, aligning it with the conveyor belt. The turning guide rail then drives the turning rollers of the turning frame to move along the length of the conveyor belt. The contact between the push plate and the soybean residue, combined with the rotation of the conveyor belt, achieves flat dispersion of the soybean residue, thus preventing accumulation. The ventilation unit of the present invention delivers airflow to all parts of the soybean residue through ventilation holes on the conveyor belt, which prevents the soybean residue from caking and makes the amount of oxygen received by the fermentation bacteria in the soybean residue more balanced, thereby further improving the air permeability of the soybean residue during the fermentation process and ensuring fermentation efficiency and uniformity. This invention pre-treats soybean residue by setting up a pre-treatment mechanism to reduce its moisture content, prevent the residue from clumping, and make the particle size of the residue more uniform, which facilitates subsequent fermentation operations. With the help of a filter rack and a permeable membrane, the water generated inside the soybean residue due to squeezing and conveying operations is collected and discharged through a drain pipe, thus removing excess water from the soybean residue.

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1 to 2As shown in the embodiment of the present invention, an apparatus for producing soybean kinase by fermentation of wet soybean residue is provided. The apparatus includes a shell 101, with several partition plates 102 fixedly connected to the inner wall of the shell 101. These partition plates 102 divide the inner cavity of the shell 101 into several vertically arranged equipment compartments. A pretreatment mechanism 2, a sterilization mechanism 4, a fermentation mechanism 3, and a drying mechanism 5 are sequentially arranged in each equipment compartment from top to bottom. The bottom of the discharge platform 204 is connected to the input end of the sterilization mechanism 4 via a crushing discharge pipe 210. The output end of the sterilization mechanism 4 is connected to the fermentation mechanism 3 via a connecting pipe 321. The output end of the fermentation mechanism 3 is connected to the input end of the drying mechanism 5 via a fermentation discharge pipe 320. A feeding hopper 103 is fixedly connected to the top of the shell 101. Below the feeding hopper 103... Corresponding to the top of the processing table 202, the output end of the drying mechanism 5 is fixedly connected to the discharge pipe 104; this constitutes the basic structure of the device, namely, the overall working sequence is as follows: wet soybean residue material (other ingredients, such as hydrophobically modified rice husk powder, can also be added to reduce the moisture content of the wet soybean residue) is fed into the feed hopper 103, the pretreatment mechanism 2 receives and mixes the material, after mixing, it is fed into the sterilization treatment mechanism 4 for sterilization, and then sent to the fermentation mechanism 3 for fermentation. After fermentation, it is sent to the drying mechanism 5 for drying and then sent out. The various mechanisms are stably connected, and the fermentation operation of the soybean residue is completed automatically. In addition, this application sets all the mechanism components inside the shell 101 to achieve the closed protection of the overall structure, effectively isolating the influence of external bacteria on the soybean residue fermentation process during production. The above-mentioned sterilization treatment mechanism 4 and drying mechanism 5 can both be implemented using existing technical means.

[0020] Please see Figure 3 and Figure 4 The fermentation mechanism 3 includes a support frame 301, and several fermentation units arranged vertically are fixedly connected inside the support frame 301. Each fermentation unit includes a conveyor frame 302, and a conveyor belt 303 is rotatably installed inside the conveyor frame 302. The conveying directions of two adjacent layers of conveyor belts 303 are opposite, and a transfer component for transferring materials is provided between adjacent conveyor belts 303. This allows for continuous transport of materials during the fermentation of soybean residue. The multi-layered conveyor belt 303 structure can extend the material transport path, which increases the bearing area. When the same amount of material is added, the conveyor belt 303 can be thinner, thus achieving uniform dispersion of materials and making the material more uniform and breathable during the fermentation process. Please see Figure 4 and Figure 5To further improve the air permeability of soybean residue during fermentation, the conveyor belt 303 is equipped with an air ventilation unit for supplying air to the belt surface. The air ventilation unit includes several air ventilation pipes 307, and a contact plate 306 is fixedly connected to the top of the air ventilation pipes 307. A through groove is opened in the middle of the contact plate 306, and the top of the contact plate 306 is in close contact with the bottom of the inner wall of the conveyor belt 303. Several air ventilation holes 305 are opened on the belt surface of the conveyor belt 303. Airflow is supplied to all parts of the soybean residue by the air ventilation unit and the air ventilation holes 305 on the conveyor belt 303, so as to prevent the soybean residue from caking and make the amount of oxygen received by the fermentation bacteria in the soybean residue more balanced, thus ensuring fermentation efficiency and uniformity.

[0021] In one embodiment, see Figure 5 A breathable cloth 304 is fixedly connected to the surface of the conveyor belt 303. The breathable cloth 304 is made of polyester staple fiber and coated with Teflon coating. This reduces the adhesion between soybean residue and the conveyor belt 303 while ensuring breathability, and facilitates the spreading, dispersion and separation of materials.

[0022] In one embodiment, see Figure 4 To further improve the uniformity of airflow dispersion inside the soybean residue and to ensure that the soybean residue is evenly dispersed, several support rods 318 are fixedly installed at intervals between several ventilation pipes 307, and a vibrator is fixedly installed inside the support rods 318.

[0023] In one embodiment, see Figure 4 and Figure 5 Above the fermentation unit is a material turning unit for agitating the materials. The material turning unit includes a material turning guide rail 315, a material turning frame 316 slidably mounted on the inner wall of the material turning guide rail 315, a directional motor 309 fixedly mounted on one side of the material turning frame 316, a material turning roller 308 fixedly connected to the output end of the directional motor 309, several material turning rods 310 fixedly connected to the top of the material turning roller 308, and a push plate 311 fixedly connected to the bottom of the material turning roller 308. The material turning guide rail 315 drives the material turning frame 316 and the material turning roller 308 to move along the length of the conveyor belt 303. The material is moved to a certain direction to agitate it and prevent the soybean residue from sticking together and clumping. The turning motor 309 drives the turning roller 308 to rotate, thereby adjusting the position and orientation of the turning rod 310 and the agitation depth. Furthermore, the rotation of the turning roller 308 can drive the push plate 311 to rotate, making it face the conveyor belt 303. Then, the turning guide rail 315 drives the turning frame 316 and the turning roller 308 to move along the length of the conveyor belt 303. The contact between the push plate 311 and the soybean residue is used to spread and disperse the soybean residue, thereby preventing the soybean residue from piling up.

[0024] In one embodiment, see Figure 4To facilitate the flow of soybean residue between adjacent layers, the transfer component includes a receiving hood 312. The bottom of the receiving hood 312 is set as an inclined surface. Through the receiving hood 312, the soybean residue sent out by the upper conveyor belt 303 is received and guided along the inclined surface into the lower conveyor belt 303. In specific implementation, the temperature of the fermentation unit in different locations can be individually controlled and adjusted by an external temperature and humidity control device to meet the temperature and humidity requirements of different fermentation stages.

[0025] In one embodiment, to prevent the soybean residue from sticking to the inclined surface, an air delivery groove 313 is provided in the middle of the inclined surface. An air delivery hood 314 is fixedly connected to one side of the bottom of the receiving hood 312. The air delivery groove 313 communicates with the inner cavity of the air delivery hood 314. An air delivery pipe 319 is fixedly connected to one side of the air delivery hood 314. The air delivery pipe 319 is fixedly connected to the output end of an external air pump. Air is delivered by the air delivery hood 314 and delivered by the air delivery groove 313, thus introducing air between the inclined surface and the soybean residue to reduce air leakage. The frictional resistance between the soybean residue and the inclined plane makes the feeding operation of the soybean residue smoother. A transfer plate 323 is set above the air supply trough 313, and the transfer plate 323 is set parallel to the inclined plane. An electric push rod 322 is set above the transfer plate 323. The output end of the electric push rod 322 is fixedly connected to the top of the transfer plate 323. The transfer plate 323 is moved by the electric push rod 322 to adjust the distance between the transfer plate 323 and the inclined plane, thereby controlling the feeding speed of the wet soybean residue.

[0026] In one embodiment, see Figure 6 and Figure 7 The pretreatment mechanism 2 includes a treatment box 201. A treatment platform 202 is fixedly installed at one end of the treatment box 201. A drive motor is fixedly installed on the treatment platform 202. The output end of the drive motor is connected to a pressing screw 203. A discharge platform 204 is provided at the other end of the treatment platform 202. A discharge port is opened on one side of the discharge platform 204. A discharge guide plate 205 is fixedly connected to the inner wall of the discharge port. An inclined guide pressure plate 206 is fixedly connected to the middle of the inner wall of the discharge platform 204 to facilitate the movement of soybean residue towards the crushing discharge pipe 210. By setting up the pretreatment mechanism 2, the soybean residue is pretreated to reduce its moisture content, prevent the soybean residue from clumping, and make the particle size of the soybean residue more uniform, which facilitates the subsequent fermentation process.

[0027] In one embodiment, see Figure 6 and Figure 7To remove excess water from the soybean residue, a filter rack 208 is fixedly connected to the bottom of the inner wall of the processing box 201. A drainage chamber is provided below the filter rack 208, and a drain pipe 209 is fixedly connected to one side of the drainage chamber. A permeable membrane 207 is fixedly connected to the top of the filter rack 208. Through the separation effect of the filter rack 208 and the permeable membrane 207, the water generated inside the soybean residue due to squeezing and conveying operations is collected and discharged through the drain pipe 209.

[0028] In one embodiment, see Figure 7 and Figure 8 Because the local heat generated during the extrusion and conveying process causes the local temperature of the soybean residue to rise, irreversible carbonized aggregates and Maillard products are produced, resulting in the loss of nutrients from the soybean residue. Therefore, this application fixes a cooling pipe 211 to the inner wall of the processing box 201, and a circulating pump 212 is fixedly installed on the top of the inner wall of the discharge platform 204. Both ends of the cooling pipe 211 are connected to the circulating pump 212, and a cooler is fixedly installed in the middle of the cooling pipe 211. The cooling pipe 211 and the cooler are used to cool down the processing box 201, thereby cooling down the soybean residue inside.

[0029] When using this device, the feed hopper 103 is opened, and the wet soybean residue raw material and other ingredients are fed in by the external feeding equipment. They are then guided into the processing box 201 through the top of the inclined processing table 202. The drive motor drives the extrusion screw to rotate, crushing and mixing the soybean residue raw material. At the same time, the circulating water pump and the cooler are started, and the cooling medium circulating in the cooling pipe 211 is used to cool the processing box 201, thereby preventing the temperature of the soybean residue raw material from getting too high. Under the rotating and pushing action of the extrusion screw, the soybean residue raw material is guided by the discharge guide plate 205 into the discharge platform 204, and then enters the sterilization treatment mechanism 4 through the crushing discharge pipe 210. After sterilization, it is inoculated with fermentation inoculum. The soybean residue after inoculation is sent to the fermentation mechanism 3 through the connecting pipe 321 for fermentation. The fermentation mechanism 3 receives the soybean residue through the conveyor belt 303. After receiving it, the rotation of the conveyor belt 303 first causes the soybean residue to be dispersed. Then, the directional motor 309 drives the turning roller 308 to rotate, so that the push plate 311 faces downward. At this time, the turning guide rail 315 drives the turning frame 316 and the turning roller 308 to rotate. 8. Lateral movement: The soybean residue is pushed and spread out by the contact between the push plate 311 and the soybean residue, so that the soybean residue is evenly distributed on the conveyor belt 303. After standing and fermenting for a period of time, the directional motor 309 drives the turning roller 308 to rotate, so that the turning rod 310 rotates downward. The turning guide rail 315 drives the turning frame 316 and the turning roller 308 to move laterally. The soybean residue is pushed and stirred by the contact between the push plate 311 and the soybean residue to prevent the soybean residue from clumping. At the same time, the air pump sends air into the air pipe 307 to the standing chamber. The contact plate 306 and the air supply hole vent the soybean residue from below, so that the soybean residue fermentation is even. After fermentation for a period of time, the soybean residue is discharged by the rotation of the conveyor belt 303. The soybean residue is then sent to the next layer of conveyor belt 303 through the receiving and conveying of the transfer piece to continue fermentation. This process is repeated until the soybean residue fermentation is completed. The fermented soybean residue is then sent to the drying mechanism 5 for drying through the fermentation discharge pipe 320. After drying, it is sent out through the discharge pipe 104.

[0030] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
