Description

Technical Field

[0001] The invention relates to the technical field of soybean deep processing, and particularly discloses continuous enzymatic hydrolysis equipment for soybean deep processing. Background Art

[0002] Soybean processing primarily extracts and utilizes its oil and protein. Soybean oil and soybean meal are the primary commercial products, with soybean meal typically obtained after oil extraction. Existing industrial soybean oil production primarily utilizes cold pressing, where soybeans are squeezed using an oil press, using intense pressure to extract the oil from the soybeans. However, soybeans have a relatively hard cell wall structure that is difficult to break, resulting in a low oil yield. To increase the oil yield of soybeans, enzymatic hydrolysis is used to pre-treat the soybean cell walls before cold pressing. This breaks down the cell wall structure, maximizes oil flow, and increases oil yield.

[0003] Existing soybean enzymatic hydrolysis treatment is usually carried out using an enzymatic hydrolysis tank. The specific steps are to put the crushed soybean material into the enzymatic hydrolysis tank, then add complex enzymes and water, and control the corresponding enzymatic hydrolysis temperature and pH value to complete the enzymatic hydrolysis of the soybean for a period of time. After the enzymatic hydrolysis treatment, high temperature is used for inactivation treatment. After the enzymatic hydrolysis liquid is discharged, the enzymatically hydrolyzed soybean material can be collected.

[0004] The utility model patent with application number 202421326089.6 discloses an enzymolysis device for improving the dispersion stability of soy protein isolate, including an enzymolysis tank, a tank cover is installed on the upper surface of the enzymolysis tank, the upper surface of the tank cover is fixedly connected with a U-shaped block and a servo motor 1, the output end of the servo motor 1 passes through the U-shaped block and extends to the inside, the output end of the servo motor 1 is fixedly connected with a bevel gear 3, the surfaces of the bevel gear 3 are respectively meshed with bevel gear 1 and bevel gear 2, the inner wall of the bevel gear 1 is fixedly connected with a connecting rod, the bottom end of the bevel gear 2 is fixedly connected with a sleeve, and the outer wall of the sleeve is fixedly connected with a stirring ring. The enzymolysis device disclosed in the patent can fully stir the internal soybean base material through the stirring ring and the stirring block, so that the enzymolytic agent is in full contact with the soybean, thereby improving the enzymolysis speed and enzymolysis temperature. However, such traditional enzymolysis devices still have some shortcomings: first, soybeans need to be inactivated at high temperature after enzymolysis is completed, which means that the enzymolysis solution needs to be replaced after each batch of soybeans is processed, resulting in a large consumption of complex enzymes; second, after a batch of soybeans is enzymolyzed, the enzymolysis solution and soybean material in the enzymolysis tank need to be discharged, filtered and separated, and then soybeans and enzymolysis solution need to be added again through the feeding pipe, and then the temperature and pH value of the internal enzymolysis solution need to be regulated again, resulting in each batch of soybeans not being able to complete the enzymolysis treatment at the highest enzymolysis speed after being added, resulting in a lower enzymolysis speed. Therefore, in response to the technical problems and shortcomings of enzymolysis treatment of soybeans by traditional enzymolysis tanks, this application proposes a newly designed continuous enzymolysis treatment equipment for deep processing of soybeans. Summary of the Invention

[0005] The purpose of the present invention is to provide a continuous enzymatic hydrolysis treatment equipment for soybean deep processing, so as to solve the technical problems and shortcomings of the existing enzymatic hydrolysis tank in the process of soybean enzymatic hydrolysis and wall breaking treatment, in which the enzyme inside the enzymatic hydrolysis tank needs to be inactivated at high temperature after each enzymatic hydrolysis treatment is completed, and then discharged and separated together with the soybeans, resulting in the consumption of complex enzymes, and the low initial enzymatic hydrolysis startup efficiency caused by each replacement of the enzymatic hydrolysis solution.

[0006] The present invention is achieved through the following technical solutions: A continuous enzymatic hydrolysis treatment device for deep processing of soybeans, comprising an enzymatic hydrolysis box and a hopper, wherein concentrically aligned feed cylinders and discharge cylinders are respectively provided on both side surfaces of the enzymatic hydrolysis box, an intermediate cylinder is rotatably provided between the inner ends of the feed cylinder and the discharge cylinder, a drainage hole is provided at the bottom of the intermediate cylinder, an enzymatic hydrolysis frame is extended upward from the upper half of the intermediate cylinder, and a through hole for infiltrating enzymatic hydrolysis liquid is provided on the enzymatic hydrolysis frame, a conveying auger blade shaft is commonly provided inside the feed cylinder, the intermediate cylinder and the discharge cylinder, and the outer end of the conveying auger blade shaft is connected to a feeding motor, the hopper is connected to the upper surface of the outer end of the feed cylinder, a heating box covering the discharge cylinder is provided on the side of the enzymatic hydrolysis box, and a heater is provided in the heating box, and a discharge channel is provided on the lower surface of the outer end of the discharge cylinder extending out of the heating box; A gear is provided on the outer circular surface of the rotating connection between the intermediate cylinder and the feed cylinder, and a telescopic device is provided on the top of the enzymatic hydrolysis box above the gear. The lower end of the telescopic device is connected to a U-shaped bar, and one side end of the U-shaped bar is provided with a rack meshing with the gear. The lower end of the U-shaped bar is connected to a strip plate located directly below the intermediate cylinder, and an ultrasonic probe is provided on the upper surface of the strip plate, and the ultrasonic probe is connected to an ultrasonic generator outside the enzymatic hydrolysis box through a wire.

[0007] As a further configuration of the above solution, a row of bellows are sealedly connected to the lower surface of the strip plate, and the lower end of each bellows is sealed and extends out of the lower surface of the enzymatic hydrolysis box and is connected to the external atmospheric pressure.

[0008] As a further arrangement of the above scheme, a plurality of ultrasonic probes are arranged in a row, and the plurality of ultrasonic probes are respectively arranged directly above each corrugated telescopic tube, and the wires connected to the bottom of the ultrasonic probes are all extended out of the enzymatic hydrolysis box along the corrugated telescopic tube and connected to the ultrasonic generator.

[0009] As a further configuration of the above solution, copper rings for sealing and lubrication are provided at the rotational connections between the two ends of the intermediate cylinder and the inner ends of the feed cylinder and the discharge cylinder.

[0010] As a further configuration of the above scheme, the enzymatic hydrolysis boxes located on the front and rear sides of the strip plate are both provided with rotating stirring shafts, on which stirring frames are provided, and the outer surface of the enzymatic hydrolysis box is provided with a stirring motor for driving the stirring shaft to rotate.

[0011] As a further configuration of the above solution, a pH sensor, a liquid level sensor and a temperature sensor are provided in the enzymatic hydrolysis box, and the pH sensor, the liquid level sensor and the temperature sensor are electrically connected to a control box.

[0012] As a further configuration of the above scheme, a compound enzyme addition part and a water injection pipe are provided on the upper side of the enzymatic hydrolysis box, a drain pipe with a valve is provided on the lower side of the enzymatic hydrolysis box, and a transparent observation window is also provided on the front side of the enzymatic hydrolysis box.

[0013] As a further configuration of the above solution, there are multiple heaters in the heating box, and the multiple heaters are evenly arranged on the inner wall of the heating box.

[0014] As a further arrangement of the above scheme, a support frame is provided at the side end of the enzymatic hydrolysis box, a circular hole for passing the hopper is opened on the top plate of the support frame, an ear seat is provided on the outer wall of the hopper above the circular hole, and a weighing sensor is provided on the top plate of the support frame directly below the ear seat. The weighing sensor is electrically connected to the control box, and a gate valve controlled by the control box is provided at the bottom of the hopper.

[0015] During operation of the soybean continuous enzymatic hydrolysis equipment disclosed in the present invention, the U-shaped bar is first moved upward by a telescopic device. During its upward movement, the meshing transmission between the gear and the rack is used to rotate the originally vertically upward enzymatic hydrolysis frame 180° to adjust it to a vertically downward position and extend into the enzymatic hydrolysis liquid at the bottom of the enzymatic hydrolysis box.

[0016] Subsequently, the hopper discharges a certain amount of soybean crushed materials each time, and transports the soybean crushed materials to the intermediate cylinder under the action of the feeding motor, feeding cylinder and conveying auger blade shaft. The soybean crushed materials entering the intermediate cylinder fall into the enzymatic hydrolysis frame under the continued push of the conveying auger blade shaft until all the soybean crushed materials discharged from the hopper fall into the enzymatic hydrolysis frame and are immersed in the enzymatic hydrolysis liquid.

[0017] At the same time, as the U-shaped bar moves upward, the strip plate connected to its bottom also moves upward to near the bottom of the enzymatic hydrolysis frame. Then, the ultrasonic probe on the strip plate accelerates the rapid contact between the material in the enzymatic hydrolysis frame and the enzymatic hydrolysis solution, thereby accelerating the speed of soybean enzymatic hydrolysis and wall breaking. In addition, the present invention also provides a stirring mechanism at the bottom of the enzymatic hydrolysis box. The stirring mechanism stirs the enzymatic hydrolysis solution up and down, and combined with ultrasonic treatment, the speed of soybean enzymatic hydrolysis and wall breaking can be greatly improved.

[0018] After the soybean enzymatic hydrolysis and wall breaking process is completed, the telescopic device is controlled to extend and reset, and then the U-shaped bar and the strip plate will move downward. During the movement, the enzymatic hydrolysis frame can be rotated from the bottom of the enzymatic hydrolysis box to the top through the engagement transmission of the gear and the rack. During the rotation, the soybean fragments after enzymatic hydrolysis and wall breaking will roll into the middle cylinder.

[0019] Finally, the heater is started to heat the discharge barrel, and then the feed motor is started again to operate the conveying auger blade shaft, thereby pushing the drained soybean crushed material in the middle barrel toward the discharge channel. It is inactivated at high temperature while moving through the heating box, and finally discharged from the discharge channel. Before the next batch of soybeans is enzymatically hydrolyzed, the various parameters of the enzymatic solution inside the enzymatic hydrolysis box can be tested, and the compound enzyme and water can be replenished in time. After the temperature and pH value are properly controlled, the next batch of soybeans can be rapidly enzymatically hydrolyzed and broken.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The continuous enzymatic hydrolysis treatment equipment for deep processing of soybeans disclosed by the present invention can realize the rotation switching of the upper and lower positions of the enzymatic hydrolysis frame by controlling the rotation adjustment of the intermediate cylinder during the enzymatic hydrolysis treatment of multiple batches of soybeans. During the enzymatic hydrolysis treatment of soybeans, the enzymatic hydrolysis frame rotates to the lowest end, and then the soybean material fed from the feed cylinder can fall into the bottom of the enzymatic hydrolysis frame and be completely immersed in the enzymatic hydrolysis solution. In addition, the stirring and ultrasonic treatment of the enzymatic hydrolysis solution can accelerate the full and rapid contact between the soybean material and the enzymatic hydrolysis solution in the enzymatic hydrolysis frame, and realize the rapid completion of the enzymatic hydrolysis wall breaking process; when the enzymatic hydrolysis treatment of soybeans is completed, the enzymatic hydrolysis frame can be rotated to the highest end again. During the rotation process, the soybeans in the enzymatic hydrolysis frame will all fall into the intermediate cylinder and complete the drainage, and then enter the discharge cylinder under the push of the conveying auger blade shaft to complete the high-temperature inactivation, and finally be discharged from the discharge channel. The entire treatment process not only achieves rapid enzymatic hydrolysis and wall breaking of soybeans, but also does not require inactivation and replacement of the enzymatic hydrolysis solution after one batch of soybeans is processed before the next batch of soybeans can be enzymatically hydrolyzed again. This greatly reduces the consumption of enzymatic hydrolysis solution and the time required for replacement and initial startup of the enzymatic hydrolysis solution, thus achieving low-cost, efficient and continuous enzymatic hydrolysis treatment of soybeans.

[0021] In the device disclosed in the present invention, when the enzymatic hydrolysis frame rotates to the lowermost end, the strip plate in the enzymatic hydrolysis box will also move upward synchronously. During the upward movement, on the one hand, the ultrasonic probe can be close to the soybean material in the enzymatic hydrolysis frame, and then in the subsequent enzymatic hydrolysis process, the enzymatic hydrolysis speed of the soybean can be accelerated by the effect of the ultrasonic wave. On the other hand, the corrugated telescopic tube connected to the lower end of the strip plate can be stretched. After the corrugated telescopic tube is stretched, the liquid level in the enzymatic hydrolysis box will rise, so that the enzymatic hydrolysis solution and the soybean can be fully contacted under the premise of less enzymatic hydrolysis solution, thereby reducing the use of enzymatic hydrolysis solution. At the same time, when the enzymatic hydrolysis frame is rotated upward after the enzymatic hydrolysis is completed, the liquid level in the enzymatic hydrolysis box will also be synchronously lowered, thereby achieving rapid separation of the enzymatic hydrolysis solution and the soybean material after the enzymatic hydrolysis treatment is completed, so that the enzymatic hydrolysis solution in the soybean material is quickly and fully drained, reducing the consumption of the enzymatic hydrolysis solution during the entire enzymatic hydrolysis process, and effectively controlling the cost of the soybean enzymatic hydrolysis treatment.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Figures 1 to 8 , and describes the application in detail with reference to embodiments. Example 1

[0026] Example 1 discloses a soybean continuous enzymatic hydrolysis treatment device, which can continuously enzymatically hydrolyze and break the soybean wall using a composite enzymatic hydrolysis solution composed of cellulase, papain, alkaline protease, etc., so as to improve the oil yield in the subsequent soybean deep processing and oil pressing process.

[0027] Reference Attachment Figures 1 to 4 The main body of the device includes an enzymatic hydrolysis box 1 and a hopper 2 with a weighing function. A support frame 3 is provided on the left side of the enzymatic hydrolysis box 1. A circular hole for the hopper 2 is opened on the top plate of the support frame 3. Then, a plurality of ear seats 201 are welded on the outer wall of the hopper 2 above the circular hole, and a weighing sensor 202 is provided on the top plate of the support frame 3 just below the ear seats 201 (see attached figure). Figure 8 ), and the weighing sensor 202 is also connected to the control box 4 set on the front side of the enzymatic hydrolysis box 1 through a wire, and a gate valve 203 is also provided at the bottom of the hopper 2. The above-mentioned design of the weighing sensor 202 and the gate valve 203, coupled with the active control of the control box 4, can realize the quantitative discharge of soybean material in the hopper 2.

[0028] Reference Attachment Figures 3 to 6 The left and right sides of the enzymatic hydrolysis box 1 are respectively fixed with a feed cylinder 5 and a discharge cylinder 6. The lower end of the hopper 2 is connected to the upper surface of the feed cylinder 5 through a hose, and a discharge channel 601 is provided at the right end of the lower surface of the discharge cylinder 6. An intermediate cylinder 7 is sealed and rotatably connected between the ends of the feed cylinder 5 and the discharge cylinder 6 located in the inner cavity of the enzymatic hydrolysis box 1, and a conveying auger blade shaft 17 is commonly provided at the center of the feed cylinder 5, the intermediate cylinder 7 and the discharge cylinder 6. A feeding motor 18 connected to the conveying auger blade shaft 17 is also provided on the end surface of the feed cylinder 5.

[0029] A row of drainage holes 701 are provided at the bottom of the intermediate cylinder 7. An enzymolysis frame 8 extends upward from the upper half of the middle position of the intermediate cylinder 7, and a through hole 801 is provided on the enzymolysis frame 8 for infiltrating the enzymolysis solution. In the specific design, the aperture of the through hole 801 should be smaller than the minimum aperture setting of the soybean material after the crushing process to prevent the soybean material from falling into the enzymolysis solution through the through hole 801. A gear 703 is fixedly welded on the outer circular surface of the left end of the intermediate cylinder 7, and a copper ring 704 is provided at the rotation connection between the intermediate cylinder 7 and the feed cylinder 5 for sealing and lubrication. Similarly, a corresponding copper ring is also provided at the rotation connection between the intermediate cylinder 7 and the discharge cylinder 6. A telescopic device 9 is provided on the top of the enzymatic hydrolysis box 1. The telescopic device 9 can be any one of a cylinder, a hydraulic cylinder or a screw lift. Then, a U-shaped bar 10 is connected to the lower end of the telescopic device 9 extending into the enzymatic hydrolysis box 1, and a rack 101 meshing with the gear 703 is provided on one side end of the U-shaped bar 10, so that during the up and down movement of the U-shaped bar 10, the stable rotation of the intermediate cylinder 7 can be achieved through the meshing transmission between the rack 101 and the gear 703.

[0030] At the bottom of the U-shaped bar 10, a strip plate 11 is fixedly connected to the bottom of the intermediate tube 7. The lower surface of the strip plate 11 is sealed with a row of corrugated telescopic tubes 12, and the lower end of each corrugated telescopic tube 12 is sealed to extend out of the lower surface of the enzymolysis box 1, and is also connected to the external atmospheric pressure. A row of ultrasonic probes 13 are installed on the upper surface of the strip plate 11, and each ultrasonic probe 13 is aligned with the corrugated telescopic tube 12 up and down. At the same time, the wires connected to the bottom of each ultrasonic probe 13 all extend out of the enzymolysis box 1 along the corrugated telescopic tube 12 and are then connected to the ultrasonic generator 14 on the front side of the enzymolysis box 1.

[0031] Finally, a heating box 15 is provided on the right side of the enzymatic hydrolysis box 1 to seal the outer periphery of the discharge barrel 6, and a plurality of heaters 16 are evenly provided on the inner wall of the heating box 15, so that the soybean material after enzymatic hydrolysis and drainage can be heated by the high temperature of the heater 16 during the process of being transported through the discharge barrel 6, thereby inactivating the complex enzyme brought out from the surface of the soybean material, and then discharged from the discharge channel 601 after inactivation.

[0032] During use of the soybean continuous enzymatic hydrolysis processing equipment disclosed in this embodiment 1, the gate valve 203 is first opened and the feeding motor 18 is started. The soybean material in the hopper 2 is conveyed to the left along the feed cylinder 5 to the intermediate cylinder 7 through the conveying auger blade shaft 17 until the soybean material discharged from the hopper 2 reaches a preset value, and then the gate valve 203 is closed and the operation of the feeding motor 18 is suspended.

[0033] Next, the telescopic device 9 is activated to lift the U-shaped bar 10 upward. During the upward movement of the U-shaped bar 10, the meshing transmission between the rack 101 and the gear 703 causes the intermediate cylinder 7 to rotate 180 degrees, thereby rotating the enzymatic hydrolysis frame 8 originally at the top to the bottom. At this time, all the soybean material in the intermediate cylinder 7 falls into the bottom of the enzymatic hydrolysis frame 8, and then the feeding motor 18 is activated to discharge all the soybean material in the feed cylinder 5 into the bottom of the enzymatic hydrolysis frame 8, so that all the soybean material at the bottom of the enzymatic hydrolysis frame 8 is completely immersed in the enzymatic hydrolysis solution.

[0034] At the same time, as the U-shaped bar 10 moves upward, the strip plate 11 moves upward synchronously, thereby stretching the originally compressed bellows 12. The extension of the bellows 12 can cause the enzymatic hydrolysis liquid at the bottom of the enzymatic hydrolysis box 1 to rise until the enzymatic hydrolysis liquid completely covers the soybean material inside the enzymatic hydrolysis frame 8 to a certain depth, thereby reducing the amount of enzymatic hydrolysis liquid used in the enzymatic hydrolysis box 1. Then, the ultrasonic generator 14 is started to operate a row of ultrasonic probes 13, which accelerates the contact between the enzymatic hydrolysis liquid and the soybean material in the enzymatic hydrolysis frame 8 through the action of ultrasonic waves, so that the soybean material is quickly enzymatically hydrolyzed and broken.

[0035] After the enzymatic hydrolysis treatment is completed for a period of time and the wall is broken, the ultrasonic generator 14 is turned off and the telescopic device 9 is controlled to extend and reset, so that the U-shaped bar 10 moves downward. During the downward movement of the U-shaped bar 10, the meshing transmission of the rack 101 and the gear 703 causes the intermediate cylinder 7 to rotate 180 degrees in the opposite direction, thereby rotating the enzymatic hydrolysis frame 8 at the bottom to the top, and during the rotation of the enzymatic hydrolysis frame 8, the enzymatically hydrolyzed soybean material inside falls into the intermediate cylinder 7. After the enzymatic hydrolyzate in the soybean material is drained, the feeding motor 18 is started again, and then the enzymatically hydrolyzed and wall-broken soybean material is conveyed through the discharge cylinder 6 under the action of the conveying auger blade shaft 17, and in this process it will be subjected to high-temperature fire extinguishing treatment by the heater 16 in the heating box 15, and finally discharged from the discharge channel 601. Example 2

[0036] Example 2 discloses a soybean continuous enzymatic hydrolysis treatment device that is further optimized based on the technical solution in Example 1. The similarities between it and Example 1 are not described again.

[0037] Reference Attachment Figure 3 and attached Figure 5In the second embodiment, a stirring shaft 19 is rotatably provided in the enzymatic hydrolysis box 1 on both the front and rear sides of the strip plate 11. A plurality of stirring racks 20 are provided on the stirring shaft 19. A stirring motor 21 for driving the stirring shaft 19 to rotate is also installed on the outer surface of the enzymatic hydrolysis box 1. Through the above design, the second embodiment can continuously stir the enzymatic hydrolysis liquid at the bottom by the stirring shaft 19 and the stirring rack 20 during the enzymatic hydrolysis and wall-breaking treatment of the soybean material by the enzymatic hydrolysis liquid, so that the complex enzyme in the entire enzymatic hydrolysis liquid is evenly distributed. In addition, the ultrasonic treatment of the ultrasonic probe on the upper surface of the strip plate 11 further improves the enzymatic hydrolysis speed of the soybean.

[0038] At the same time, a composite enzyme addition portion 22 and a water injection pipe 23 are provided at the upper end of the left side of the enzymolysis box 1, and a drain pipe 24 with a valve is provided at the lower end of the right side of the enzymolysis box 1. Through the above design, corresponding substances can be added as needed to supplement the enzymolysis solution or adjust the pH value of the enzymolysis solution, and then the enzymolysis solution in the enzymolysis box 1 can be emptied and replaced through the drain pipe 24. In addition, a transparent observation window 25 is provided on the front side of the enzymolysis box 1 to facilitate observation of the internal soybean enzymolysis situation.

[0039] Finally, a pH sensor, a liquid level sensor and a temperature sensor (not shown) are also provided in the enzymatic hydrolysis box 1, and all three are electrically connected to the control box 4, so that they can actively monitor various parameters of the entire enzymatic hydrolysis process, making it convenient for operators to adjust the environmental parameters of the enzymatic hydrolysis solution in time to ensure that the enzymatic hydrolysis solution can complete the enzymatic hydrolysis and wall breaking treatment of soybeans at the maximum speed.

[0040] 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 scope of protection of the present invention.
