Abstract
Description
Technical Field
[0001] The utility model relates to the field of modified starch screening, in particular to a modified starch screening device for impurity removal. Background Technique
[0002] Modified starch is based on the inherent properties of natural starch. To improve the performance of starch and expand its application range, physical, chemical or enzymatic treatment is used to introduce new functional groups on the starch molecules or change the starch molecular size and starch granule properties, thereby changing the natural properties of starch and making it more suitable for certain application requirements. Modified starch has the texture properties of many products and is widely used in the food industry as a thickener, stabilizer, gelling agent, binder, etc.
[0003] At the present stage, before putting modified starch into production, a screening device is used to screen the modified starch to separate the impurities therein, and the pure modified starch is put into production.
[0004] However, when the existing screening device feeds materials, due to the large amount of modified starch to be screened, each time of feeding, it is easy to be blocked at the lower end of the feeding port, resulting in a slow screening rate and low production efficiency. This method not only wastes labor costs but also causes waste of modified starch. Content of the Utility Model
[0005] Based on this, the purpose of the utility model is to provide a modified starch screening device for impurity removal to solve the technical problems mentioned in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical scheme: a modified starch screening device for impurity removal, including a feeding port, an impurity discharge port, a finished product discharge port, a screening chamber, a finished product chamber, a screening mesh, a fixing plate, a spring and a base. A vibration motor is fixedly installed on the side of the finished product chamber and is located on both sides of the finished product discharge port. The screening mesh is rotatably installed in the screening chamber, and a motor corresponding to the screening chamber is installed on the base. A guide plate is installed on the inner wall of the screening chamber, and a guide plate located below the feeding port is installed at the end of the guide plate.

[0007] By adopting the above technical solution, the screening mesh, the motor, the rotating shaft, the scraper and the conical deflector are used in cooperation. When the modified starch enters the feed inlet, the motor drives the rotating shaft and the screening mesh. Under the action of the vibration motor, after the modified starch passes through the conical deflector, the modified starch is dispersed. At the same time, the scraper sweeps off the modified starch remaining at the end of the conical deflector, reducing the waste of modified starch, improving the production efficiency, and avoiding the situation where the modified starch accumulates below the feed inlet.

[0010] The present utility model is further configured such that the rotating shaft is located at the center of the screening mesh, and the rotating shaft is fixedly connected to the screening mesh.
[0011] By adopting the above technical solution, when the motor rotates the rotating shaft, the screening mesh rotates with the rotating shaft, realizing the rotation of the screening mesh.
[0012] The present utility model is further configured such that the top cross-section of the material guiding plate is designed in a conical shape, and the top of the material guiding plate is in contact with the bottom of the scraper.
[0013] By adopting the above technical solution, the conical design of the top cross-section of the material guiding plate effectively guides the modified starch, and the top of the material guiding plate is in contact with the bottom of the scraper, so that the modified starch remaining on the top of the material guiding plate is scraped into the screening mesh, reducing the waste of modified starch.
[0014] The present utility model is further configured such that the springs are uniformly and fixedly installed at the end of the base, and the springs are fixedly connected to the fixing plate.
[0015] By adopting the above technical solution, when vibrating, the vibration of the base is reduced, and tipping over during work is avoided.
[0016] The present utility model is further configured such that the length of the scraper corresponds to the diameter of the top of the material guiding plate, and the height of the scraper is less than the gap between the end of the material guiding plate and the bottom of the feed inlet.
[0017] By adopting the above technical solution, it can be ensured that when the scraper rotates, the modified starch remaining on the top of the material guiding plate is completely scraped off, avoiding waste.
[0018] The present utility model is further configured such that a plurality of inclined grooves are equiangularly installed on the material guiding plate, and the width of the top of the inclined groove is smaller than the width of its bottom.
[0019] By adopting the above technical solution, the clogging of the modified starch in the material guiding plate is avoided, and multiple inclined grooves can make the material guiding effect better and the screening rate faster.

[0021] By adopting the above technical solution, the plurality of material guiding plates not only play a role in supporting the material guiding plate, but also guide the modified starch, avoiding the situation of accumulation.
[0022] In summary, the present utility model mainly has the following beneficial effects:
[0023] The present utility model is provided with a screening net, a motor, a rotating shaft, a scraper and a conical diversion plate in cooperation. When the modified starch enters the feed port, the motor drives the rotating shaft and the screening net. Under the action of the vibration motor, after the modified starch passes through the conical diversion plate, the modified starch is dispersed, and at the same time, the scraper sweeps down the modified starch remaining at the end of the conical diversion plate, reducing the waste of the modified starch, improving the production efficiency, and avoiding the situation that the modified starch accumulates below the feed port.

The screening mesh 6 is rotatably installed in the screening chamber 4, and a motor 10 corresponding to the screening chamber 4 is installed on the base 9. When the motor 10 rotates, it drives the screening mesh 6 to rotate. At this time, the screening mesh 6 rotates and turns, accelerating the screening rate. A guide plate 15 is installed on the inner wall of the screening chamber 4, and a guide plate 14 located below the feed inlet 1 is installed at the end of the guide plate 15. The guide plate 15 makes the guide plate 14 suspended in the screening chamber 4, improving the space utilization rate. The shape of the guide plate 15 helps the guiding of the modified starch, so that the modified starch is dispersed. And a scraper 13 connected to the motor 10 is rotatably installed on the top of the guide plate 14 for cleaning the top of the guide plate 14, reducing the waste of the modified starch and improving the utilization rate of the modified starch. A rotating shaft 12 connected to the scraper 13, the screening mesh 6 and the motor 10 is rotatably installed on the guide plate 14, and an inclined slot 16 for the passage of the modified starch is formed through the top of the guide plate 14, avoiding the blockage of the modified starch during feeding.
[0032] Please refer to Figure 2 , the gap between the bottom of the guide plate 14 and the surface of the screening mesh 6 is 30 mm, and the center point of the guide plate 14 and the center point of the feed inlet 1 are located on the same vertical line, so that when feeding, the modified starch enters the screening mesh 6 from the guide plate 14, diverting a large amount of the modified starch, and the gap between the end of the guide plate 14 and the bottom of the feed inlet 1 is greater than 25 cm.
[0033] Please refer to Figure 2 , the rotating shaft 12 is located at the center of the screening mesh 6, and the rotating shaft 12 is fixedly connected to the screening mesh 6, so that when the motor 10 rotates the rotating shaft 12, the screening mesh 6 rotates with the rotating shaft 12, realizing the rotation of the screening mesh.
[0034] Please refer to Figure 2 and Figure 3 , the top cross-section of the guide plate 14 is designed in a conical shape, effectively guiding the modified starch, and the top of the guide plate 14 is in contact with the bottom of the scraper 13, so that the modified starch remaining on the top of the guide plate 14 is scraped into the screening mesh 6, reducing the waste of the modified starch.
[0035] Please refer to Figure 1The spring 8 is evenly fixedly installed on the end of the base 9 so that when vibrating, the vibration of the base 9 is reduced, and the spring 8 is fixedly connected to the fixing plate 7.
[0036] See also Figure 2 and Figure 3 The length of the scraper 13 corresponds to the diameter of the top of the guide disk 14, ensuring that the modified starch remaining on the top of the guide disk 14 can be completely scraped off when the scraper rotates, and the height of the scraper 13 is smaller than the gap between the end of the guide disk 14 and the bottom of the feed port 1 to avoid being blocked by the scraper 13 during feeding.
[0037] See also Figure 4 A plurality of inclined grooves 16 are installed at equal angles on the material guide plate 14 to achieve a better material guide effect, and the width of the top of the inclined groove 16 is smaller than the width of the bottom thereof to prevent the modified starch from being blocked in the material guide plate 14 .
[0038] See also Figure 2 - Figure 4 A plurality of guide plates 15 are installed at equal angles in the screening chamber 4, and the plurality of guide plates 15 are connected to the guide disc 14 to fix the guide disc 14, and the installation position of the guide plate 15 is staggered with the impurity discharge port 2, and the cross-section of the guide plate 15 is designed to be triangular to avoid waste of modified starch.
[0039] The working principle of the utility model is as follows: when the motor 10 and the vibration motor 11 start to work, the modified starch enters the screening chamber 4 from the feed port 1 and falls on the conical guide plate 14. Part of the modified starch falls on the screening net 6 from the trapezoidal through holes on the conical guide plate 14. The inclined slot 16 at the bottom end of the conical guide plate 14 allows the modified starch entering the trapezoidal through holes to quickly fall on the screening net 6 to avoid clogging the trapezoidal through holes on the conical guide plate 14. A small amount of modified starch remains on the surface of the conical guide plate 14. At this time, the motor 10 drives the rotating shaft 12 to rotate the scraper 13 fixedly connected to the rotating shaft 12 to move the cone. The modified starch remaining on the surface of the trapezoidal guide plate 14 falls onto the screening mesh 6 from the trapezoidal through holes. The screening mesh 6 fixedly connected to the rotating shaft 12 rotates driven by the motor 10, and the vibration motor 11 vibrates the device body. At this time, the screening mesh 6 rotates while rotating. The finished modified starch enters the finished product cavity 5 from the screening mesh 6 and is then discharged from the finished product discharge port 3, while the impurities are left in the screening cavity 4 and then enter the impurity discharge port 2, thereby realizing the separation of impurities in the modified starch, effectively solving the problem of blockage of the modified starch during feeding, improving production efficiency, and reducing the waste of modified starch and labor.
