Description

Technical Field

[0001] This utility model relates to the field of starch processing technology, and in particular to a precipitation device for soluble starch processing. Background Technology

[0002] During starch production and processing, substances such as protein, fat, and ash need to be separated and removed. Soluble starch is insoluble in cold water, and the different proportions of these substances result in different settling rates in the suspension. The main methods are static sedimentation, fluidized bed sedimentation, and centrifugal separation. Static sedimentation involves placing the starch slurry in a sedimentation device, allowing it to stand, causing the starch to precipitate and the protein to remain suspended in the water. The upper layer of protein water is then released, and fresh water is introduced and stirred. This process is repeated multiple times to clean the starch.

[0003] In related technologies, patent application number CN201921403285.8 discloses a sedimentation device for soluble starch processing, including a sedimentation tank shell. A valve adjusting assembly is fixedly installed on the outer side of the sedimentation tank shell. The valve adjusting assembly includes a first lead screw, a screw cap, a first slide cylinder, a lead screw connector, a second slide cylinder, and a return spring. The first slide cylinder is fixedly installed on the outer surface of the sedimentation tank shell, and the outer surface of the first slide cylinder has longitudinally distributed strip-shaped slots that communicate with the sedimentation tank shell. The screw cap is screwed and fixed to the upper end of the first slide cylinder. By designing the valve adjusting assembly, rotating the first lead screw can control the opening and closing of the strip-shaped slots. The slots open downwards from the upper end, making it easy to control the strip-shaped slots to be on the same plane as the starch sedimentation surface, so that the protein water inside the sedimentation tank shell can be completely discharged, improving cleaning efficiency. However, after the protein water is discharged, clean water is added again, which does not make full use of the water in the protein water and consumes a lot of water resources. Therefore, we propose a sedimentation device for soluble starch processing.

[0004] The information disclosed in this background section is only for understanding the background technology of the inventive concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] The purpose of this invention is to provide a sedimentation device for soluble starch processing, in order to solve the problem mentioned in the background art that after removing the protein water, the device needs to add fresh water again, which does not make full use of the water in the protein water and consumes a lot of water resources.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] Reference Figure 1 , 2 3, 4, A sedimentation device for soluble starch processing includes a base plate 1, an electric telescopic column 4, a device housing 6, and a drain tank 7. The device housing 6 is fixedly installed at the upper center of the base plate 1. The drain tank 7 is welded and sealed on the right side of the device housing 6. A drain groove is opened at the corresponding position of the drain tank 7 on the device housing 6. A sealing strip 21 is integrally formed on the inner wall of the device housing 6 at the corresponding position of the drain groove. A sealing groove is opened in the sealing strip 21. A sealing block 22 is installed in the sealing groove and sealed. The sealing block 22 is fitted and sealed to the inner wall of the device housing 6. A connecting plate 23 is horizontally fixed on the upper end of the sealing block 22 near the drain tank 7. The end of the connecting plate 23 away from the device housing 6 is engaged in a groove on the inner wall of the drain tank 7. A rotating sleeve is set at the upper center of the connecting plate 23. A screw 9 is installed in a rotating manner. The upper end of the screw 9 is threaded into the top cover of the drain tank 7. A handle 8 is installed at the upper end of the screw 9. An ultrafiltration membrane 10 is detachably installed on the lower side of the drain tank 7. The ultrafiltration membrane 10 is horizontally installed inside the drain tank 7. The lower end of the drain tank 7 is connected to the water storage tank 11 through a conduit. An electric control valve is installed on the conduit. A connecting pipe 13 is connected to the front end of the water storage tank 11. By rotating the screw 17, the connecting plate 23 and the sealing block 22 move downward. Since the height of the drain tank is half the height of the device shell, during the downward movement of the sealing block 22, the protein water flows from the upper end of the sealing block 22 into the drain tank 7. Under the filtration of the ultrafiltration membrane 10, the water and protein are separated, and the water is transported back into the device shell 6 to wash the starch, thereby improving the efficiency of water resource utilization.

[0024] In specific implementation of the embodiments of this utility model, such as Figure 1 , 2 As shown, a water pump 12 is installed on the connecting pipe 13. The connecting pipe 13 is connected and fixed to the front end of the device housing 6 through the fixing sleeve 14. An annular pipe 15 is connected to the upper end of the connecting pipe 13. The annular pipe 15 is connected to the upper end of the device housing 6 through the fixing sleeve 14. The annular water pipe 15 is provided to facilitate the delivery of circulating water to the device housing 6.

[0025] In specific implementation of the embodiments of this utility model, such as Figure 1 , 3 As shown, multiple sets of nozzles 25 are inclined and spaced at the lower end of the annular tube 15. An electric telescopic column 4 is vertically fixed on the upper left side of the base plate 1. An installation plate 5 is horizontally welded to the upper end of the electric telescopic column 4. A rotating stud 17 is rotatably installed inside the right side of the installation plate 5. The left side of the rotating stud 17 is connected to the motor output end inside the installation plate 5. The motor is installed in the motor box 16 of the installation plate 5. By designing the installation plate 5, it is easy to control the position of the stirring motor 19 and the stirring blade 20. In conjunction with the electric telescopic column 4, the stirring blade 20 can be fully and evenly stirred, thereby improving the starch washing efficiency.

[0026] In specific implementation of the embodiments of this utility model, such as Figure 1 , 2 As shown, a mounting block 18 is threadedly engaged on the side of the rotating stud 17. A stirring motor 19 is fixedly mounted on the lower end of the mounting block 18. A drive shaft is connected to the lower output end of the stirring motor 19. A stirring blade 20 is welded to the side of the drive shaft. Support columns 2 are symmetrically and vertically mounted on the left and right sides of the lower end of the base plate 1. A controller 3 is mounted on the upper left side of the base plate 1. The controller 3 effectively improves the automation level of the device. A water replenishment pipe is provided on the other side of the annular pipe 15 to replenish cleaning water when the circulating water is insufficient. A protein outlet is provided on the side of the drain tank 7 at the upper end of the ultrafiltration membrane 10 for recovering filtered protein.

[0027] In this embodiment, all components are general standard parts or components known to those skilled in the art. Their structure and connection principle can be known to those skilled in the art through technical manuals or conventional experimental methods. The starch solution to be treated is placed into the outer shell 6 of the device. At this time, the seal 22 is in a high position and is tightly attached to the inner wall of the outer shell 6 of the device to prevent the liquid from flowing directly into the drain tank 7. The motor on the electric telescopic column 4 is started, and the position of the mounting plate 5 is adjusted by rotating the stud 17, thereby controlling the height of the stirring motor 19 and the stirring blade 20. Driven by the drive shaft, the stirring blades 20 begin to work, thoroughly stirring the starch solution inside the device housing 6 to improve cleaning efficiency and uniformity. When it is necessary to drain water containing protein, the operator rotates the handle 8 on the screw 9, causing the connecting plate 23 and its connected sealing block 22 to move vertically downwards. As the sealing block 22 descends, the drain tank is gradually exposed, allowing the upper clear liquid (i.e., water containing less starch but more protein) to flow from the device housing 6 to the drain tank 7. The liquid entering the drain tank 7 is filtered through the ultrafiltration membrane 10, where larger protein particles are trapped on or above the membrane surface, while relatively pure water permeates through the membrane. The water is fed into the lower water storage tank 11. The clean water stored in the tank 11 is then pumped back into the outer casing 6 via a conduit, an electrically controlled valve, and a water pump 12, through a ring pipe 15 and its nozzle 25, for further starch washing. This forms a closed water circulation system, improving water resource utilization. If insufficient water is detected during circulation, new washing water can be added through the replenishment pipe on the other side of the ring pipe 15. Protein accumulated above the ultrafiltration membrane 10 can be collected through the discharge port on the side of the drain tank 7 for subsequent processing or sale as a byproduct. After all steps are completed, the power is turned off, and the equipment is stopped. Clean all components, especially the ultrafiltration membrane, if necessary to ensure cleanliness for the next use.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
