[0035] In a preferred embodiment, please refer to Figure 3 And Figure 4 The top of processing straight barrel 101 is provided with feeding pipe 113 with electromagnetic valve, and the bottom of processing straight barrel 101 is provided with base 105 and first driving motor 106, and closed pad 103 and first scraper 104 are arranged in concentration cylinder 102, and concentration cylinder 102 is notched cylinder structure, vacuum pump 109 and discharge flat nozzle pipe 111 are arranged on drying cylinder 110, discharge hole 112 with electromagnetic valve inside is arranged on discharge flat nozzle pipe 111, second scraper 108 is fixedly arranged in the inside of drying cylinder 110, fourth driving motor 116 is fixedly arranged on the outer wall of concentration cylinder 102, third driving motor 115 is fixedly arranged on the outer wall of drying cylinder 110, and second driving motor 114 is fixedly arranged on the outer wall of discharge cylinder 107.

[0036] In a preferred embodiment, please refer to Figure 5 Pull extrusion arm assembly 200 includes pull shaft arm 201, and pull convex arm 203 is fixedly arranged on the top and bottom of pull shaft arm 201, and driving gear 202 is fixedly arranged on the top of pull shaft arm 201, and extrusion disc 207 is arranged on both sides of pull shaft arm 201, and extrusion disc 207 is fixed on fixed end arm 205 through auxiliary support arm 206, and auxiliary arm 204 is hinged between pull convex arm 203 and fixed end arm 205.

[0037] In this embodiment, the auxiliary support arm 206 slides through the side cylinder of the processing cylinder 101. At this time, the two extrusion discs 207 on the traction extrusion arm assembly 200 slide on both sides of the processing cylinder 101. The bottom of the traction shaft arm 201 is connected to the output end of the first drive motor 106. The traction protrusion arm 203 is located outside the processing cylinder 101, and the drive gear 202 is located inside the processing cylinder 101.

[0038] Secondly, please refer to it again. Figures 1-5 The first drive motor 106 drives the traction shaft arm 201 on the traction extrusion arm assembly 200 to rotate. When the traction shaft arm 201 rotates, it drives the two traction protrusion arms 203 at its top and bottom to rotate. When the traction protrusion arm 203 rotates, it pulls the extrusion disc 207 on the fixed end arm 205 through the two auxiliary arms 204. In this way, the two extrusion discs 207 are pulled closer together in the processing cylinder 101, thereby realizing the extrusion of the hydrolysate in the processing cylinder 101.

[0039] In a preferred embodiment, please refer to Figure 8 The dynamic ultrasonic homogenizing component 300 includes a fixed arm tube 301, a rotating arm tube 302 rotatably disposed in the middle of the fixed arm tube 301, a fixed disk 306 fixedly disposed at the top of the rotating arm tube 302, a plurality of linkage arms 307 rotatably disposed on the fixed disk 306, a linkage gear 308 and a driving bevel gear 305 respectively fixedly disposed at the top and bottom of the linkage arms 307, a guide rail gear ring 309 fixedly disposed on the inner wall of the top of the fixed arm tube 301, an ultrasonic head 304 rotatably disposed on the wall of the rotating arm tube 302, and a driven bevel gear 303 fixedly disposed on the ultrasonic head 304.

[0040] In this embodiment, the top and bottom of the fixed arm tube 301 are fixed to the top and bottom of the center of the processing cylinder 101. At this time, the fixed arm tube 301 is sleeved on the outside of the traction shaft arm 201. The driving gear 202 is arranged among multiple linkage gears 308. The inner side of the linkage gear 308 meshes with the driving gear 202, and the outer side of the linkage gear 308 meshes with the guide rail tooth ring 309. The driving bevel gear 305 meshes with the driven bevel gear 303.

[0041] Secondly, please refer to it again. Figures 1-8When the traction shaft arm 201 rotates, the traction shaft arm 201 drives the multiple linkage gears 308 on the dynamic ultrasonic homogenizing component 300 to mesh and rotate through the drive gear 202. Since the outer side of the linkage gear 308 meshes with the guide rail gear ring 309, when the drive gear 202 rotates, it will drive the linkage gear 308 to rotate around the drive gear 202 and rotate on its own axis, that is, drive the linkage arm 307 to rotate around and rotate on its own axis. When the linkage arm 307 rotates around, it will drive the multiple ultrasonic heads 304 on the rotating arm tube 302 to rotate around inside the processing cylinder 101. When the linkage arm 307 rotates on its own axis, it will drive the ultrasonic heads 304 to rotate on their own axis through the drive bevel gear 305 and the driven bevel gear 303.

[0042] In a preferred embodiment, please refer to Figure 6 and Figure 7 A heating rod 401 is fixedly installed on the inner wall of the drying roller 400. Multiple discharge grooves 501 are opened on the sealed discharge roller 500. A backflushing flat tube 602 with a water-receiving wide cover 601 is installed inside the concentrating filter roller 600. A fixed side block 603 is fixedly installed on one side of the backflushing flat tube 602. A filter membrane for filtering and concentrating hydrolysate is installed on the roller wall of the concentrating filter roller 600.

[0043] Secondly, please refer to it again. Figure 1 and Figure 6 The drying roller 400 is rotatably disposed inside the drying cylinder 110, and the drying roller 400 is driven by the third drive motor 115. The second scraper 108 scrapes off the deposits on the outer wall of the drying roller 400.

[0044] In this embodiment, the concentrate in the straight cylinder 101 is coated onto the rotating drying roller 400 through the discharge flat nozzle pipe 111. The vacuum pump 109 creates a vacuum environment inside the drying cylinder 110, and the heating rod 401 heats the outer wall of the drying roller 400. Through this coating method, the concentrate is dried at low temperature in a vacuum on the outer wall of the drying roller 400.

[0045] The aforementioned third drive motor 115 drives the drying roller 400 to rotate inside the drying cylinder 110. This rotation ensures that the material can be evenly coated on all surfaces of the outer wall of the drying roller 400, and also facilitates the subsequent scraping of the material off the outer wall of the drying roller 400 by the second scraper 108.

[0046] Secondly, please refer to the following as well. Figure 1 and Figure 7 The thickening filter roller 600 is rotatably disposed inside the thickening cylinder 102, and the thickening filter roller 600 is driven by the fourth drive motor 116. The first scraper 104 scrapes off the deposits on the outer wall of the thickening filter roller 600.

[0047] In this embodiment, the backflushing flat tube 602 is fixed to the inner wall of the concentration cylinder 102 by the fixed side block 603. The backflushing flat tube 602 collects the water filtered from one side of the concentration filter roller 600 through the water receiving wide cover 601, and the water outlet of the backflushing flat tube 602 faces the other side of the concentration filter roller 600 to form a backflushing structure.

[0048] Secondly, please refer to the following as well. Figure 1 and Figure 7 The fourth drive motor 116 drives the thickening filter membrane roller 600 to rotate inside the thickening cylinder 102. On the one hand, it realizes the rolling and changing of the filter membrane on the thickening filter membrane roller 600 to avoid clogging when filtering with a single filter membrane and ensure the high efficiency of filter membrane filtration. At the same time, through this rotation, the filter membrane surfaces before and after the thickening filter membrane roller 600 are interchanged, so that the backwash flat tube 602 backwashes the interchanged filter membrane surfaces.

[0049] Secondly, please refer to the following as well. Figure 1 and Figure 6 The closed discharge roller 500 is rotatably disposed inside the discharge cylinder 107, and the closed discharge roller 500 is driven by the second drive motor 114.

[0050] In this embodiment, the material scraped off the outer wall of the drying cylinder roller 400 by the second scraper 108 falls into the discharge groove 501 on the sealed discharge roller 500. The sealed discharge roller 500 is provided with multiple discharge grooves 501. When the sealed discharge roller 500 rotates, it drives the discharge groove 501 to rotate up and down in the discharge cylinder 107, realizing the rotation of the discharge groove 501 to receive and discharge material. At the same time, through this rotation of receiving and discharging material, the sealed discharge roller 500 keeps the bottom of the drying cylinder 110 sealed. This design ensures smooth receiving and discharging of material inside the drying cylinder 110, while avoiding damage to the airtightness of the drying cylinder 110 during receiving and discharging, thereby reducing the damage to the vacuum inside the drying cylinder 110.

[0051] A process for concentrating and drying fermented cottonseed protein hydrolysate, using the aforementioned equipment for concentrating and drying fermented cottonseed protein hydrolysate, includes the following process steps:

[0052] S1: Hydrolysate feeding stage, the fermented cottonseed protein hydrolysate is pumped from the feeding pipe 113 into the processing cylinder 101;

[0053] S2: During the hydrolysate rolling and face-changing concentration stage, the first drive motor 106 is started to drive the pulling and extruding arm assembly 200 to move. The two extrusion discs 207 on the pulling and extruding arm assembly 200 come together to compress and extrude the hydrolysate. At this time, the fourth drive motor 116 is started to drive the concentration filter roller 600 to rotate inside the concentration cylinder 102. At this time, the water in the pressurized hydrolysate is discharged from the rolling concentration filter roller 600, which realizes the rolling and face-changing concentration of the hydrolysate by the concentration filter roller 600. The discharged water is used to perform rolling and face-changing backwashing on the concentration filter roller 600 through the backwash flat tube 602.

[0054] S3: The hydrolysate is dried under vacuum at low temperature. At this time, the first drive motor 106 continuously squeezes the concentrate in the processing cylinder 101 through the pulling extrusion arm assembly 200. At this time, the third drive motor 115 is started to drive the drying cylinder roller 400 to rotate in the drying cylinder 110 and open the solenoid valve in the discharge hole 112.

[0055] S4: During the discharge stage after the hydrolysate is dried, when the drying roller 400 rotates inside the drying cylinder 110, the second scraper 108 scrapes off the material adhering to the outer wall of the drying roller 400. The scraped dry material falls into the discharge trough 501 on the closed discharge roller 500. The closed discharge roller 500 is driven to rotate inside the discharge cylinder 107 by the second drive motor 114. The closed discharge roller 500 drives the discharge trough 501 to rotate up and down inside the discharge cylinder 107, realizing the rotation of the discharge trough 501 to receive and discharge material.

[0056] The working principle of this invention is as follows: When drying and concentrating fermented cottonseed protein hydrolysate, the hydrolysate is first fed into the processing cylinder 101 through an external pump and feeding pipe 113. At this time, the first drive motor 106 drives the traction shaft arm 201 on the traction extrusion arm assembly 200 to rotate. When the traction shaft arm 201 rotates, it drives the two traction protrusion arms 203 at its top and bottom to rotate. When the traction protrusion arm 203 rotates, it pulls the extrusion disc 207 on the fixed end arm 205 through two auxiliary arms 204. In this way, the two extrusion discs 207 are pulled closer in the processing cylinder 101, thereby squeezing the hydrolysate in the processing cylinder 101.

[0057] Based on the above, when the hydrolysate in the processing cylinder 101 is squeezed, the water in the hydrolysate is discharged from the filter membrane on the concentrating filter roller 600 during the squeezing process, thereby achieving the concentration of the hydrolysate. The squeezed-out water is rinsed on the other side of the concentrating filter roller 600 through the water receiving cover 601 and the backwash flat tube 602. In actual use, the fourth drive motor 116 drives the concentrating filter roller 600 to rotate inside the concentrating cylinder 102. In this way, on the one hand, the filter membrane on the concentrating filter roller 600 is rolled and the filter membrane is changed to avoid clogging when filtering with a single filter membrane, thus ensuring the high efficiency of filter membrane filtration. At the same time, through this rotation, the filter membrane surfaces before and after the concentrating filter roller 600 are swapped, so that the backwash flat tube 602 backwashes the swapped filter membrane surfaces.

[0058] Based on the above, when drying the concentrated hydrolysate, it is necessary to ensure that the first drive motor 106 continues to drive the pulling and extruding arm assembly 200 to rotate. At this time, the hydrolysate in the processing cylinder 101 is always under pressure. Then, the solenoid valve in the discharge hole 112 is opened, allowing the hydrolysate in the processing cylinder 101 to be coated onto the drying roller 400 through the discharge flat nozzle 111. At this time, the vacuum pump 109 is started to create a negative pressure environment inside the drying cylinder 110, and the outer surface of the drying roller 400 is heated by the heating rod 401. Through this vacuum negative pressure low-temperature heating method, the drying roller 400 can be kept in a stable state. The coating material on the outer wall can dry quickly. At the same time, the use of this vacuum negative pressure low-temperature heating method avoids the denaturation and damage of proteins in the hydrolysate by high temperature. By coating and drying on the outer wall of the drying roller 400, the material can be kept in a thin layer on the outer wall of the drying roller 400, which facilitates the subsequent drying of the material. While coating and drying, the third drive motor 115 drives the drying roller 400 to rotate inside the drying cylinder 110. This rotation ensures that the material can be evenly coated on all surfaces of the outer wall of the drying roller 400, and also facilitates the subsequent scraping of the material on the outer wall of the drying roller 400 by the second scraper 108.

[0059] Based on the above, during the drying and rotating scraping actions, the second drive motor 114 drives the sealed discharge roller 500 to rotate inside the discharge cylinder 107. At this time, the material scraped off the outer wall of the drying cylinder roller 400 by the second scraper 108 falls into the discharge trough 501 on the sealed discharge roller 500. The sealed discharge roller 500 is provided with multiple discharge troughs 501. When the sealed discharge roller 500 rotates, it drives the discharge troughs 501 in the discharge cylinder. The up-and-down rotation within 107 enables the rotating material receiving and discharging mechanism of the discharge trough 501. Simultaneously, this rotating material receiving and discharging action ensures that the sealed discharge roller 500 remains sealed to the bottom of the drying cylinder 110. This design guarantees smooth material receiving and discharging within the drying cylinder 110 while preventing damage to the airtightness of the drying cylinder 110 during material receiving and discharging, thereby reducing the disruption to the vacuum level inside the drying cylinder 110.

[0060] It should be emphasized that during the concentration and drying process, the traction extrusion arm assembly 200 is always in a state of squeezing the inside of the processing cylinder 101. When the raw material inside the processing cylinder 101 is concentrated, it can also be dried at the same time. The concentration and drying processes can be carried out simultaneously, avoiding the trouble of frequent material handling caused by the separation of traditional processes.

[0061] Based on the above, that is, during the concentration and drying process, the traction extrusion arm assembly 200 is always in a state of extrusion on the inside of the processing cylinder 101. At this time, the traction shaft arm 201 is always in a state of rotation. When the traction shaft arm 201 rotates, it drives multiple linkage gears 308 on the dynamic ultrasonic homogenizing assembly 300 to mesh and rotate through the drive gear 202. Since the outer side of the linkage gear 308 meshes on the guide rail gear ring 309, when the drive gear 202 rotates, it will drive the linkage gear 308 to rotate around the drive gear 202, that is, drive the linkage arm 307 to rotate. When the arm 307 rotates, it drives multiple ultrasonic heads 304 on the rotating arm tube 302 to rotate within the processing cylinder 101. When the linkage arm 307 rotates, it drives the ultrasonic heads 304 to rotate via the active bevel gear 305 and the driven bevel gear 303. In this way, the rotation and self-rotation of multiple ultrasonic heads 304 on the dynamic ultrasonic homogenizing component 300 are realized. In this way, on the one hand, the ultrasonic heads 304 homogenize the hydrolysate, and on the other hand, the above-mentioned rotation and self-rotation realize the dynamic homogenization of the hydrolysate, thereby ensuring the homogenization effect and the consistency of homogenization in the processing cylinder 101 during concentration and drying.
