Description

Technical Field

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

[0002] Starch is a polysaccharide composed of glucose molecules. It is a way for plants to store energy during growth and is found in the seeds, tubers, and rhizomes of plants. Under normal conditions, it is a white powder that is tasteless and odorless and insoluble in cold water. Starch extracted from plant raw materials contains a large amount of water. In order to facilitate storage, transportation, and subsequent processing, dehydration devices for starch processing have been developed.

[0003] Starch processing dehydration devices combine mechanical extrusion, centrifugal separation, or vacuum dehydration technologies to efficiently remove moisture from starch. Through the centrifugal force generated by high-speed rotation or the strong suction of vacuum negative pressure, moisture is quickly separated from starch granules, significantly improving dehydration efficiency and effectively reducing the moisture content of starch to meet the requirements of different production scenarios for starch moisture content.

[0004] Although dehydration devices for starch processing offer great convenience in dehydrating starch, the filter screen is a component that is prone to clogging and damage. However, the filter screen is installed in a relatively concealed location, and the disassembly and installation process is complicated, requiring a lot of time and manpower for cleaning or replacement, which affects the normal operation time and maintenance costs of the equipment. The existing solution is to design a quick-release filter screen structure to facilitate the disassembly and installation of the filter screen, and to set a rotating cleaning arm or high-pressure water gun interface inside the cavity to facilitate the cleaning of the inner wall of the cavity. However, after long-term and frequent disassembly, the connection parts of the quick-release filter screen structure become loose, and the cleaning arm or high-pressure water gun cannot completely remove starch residue from the corners and complex structures of the cavity.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 3 , Figure 4 and Figure 6This utility model provides an embodiment of a starch processing dehydration device, comprising a base plate 1, a dehydration tank 2, and a conveying pipe 3. A double-layer filter screen 5 is fixedly connected to the middle of the inner wall of the dehydration tank 2. The double-layer filter screen 5 is used to filter starch mixtures. A micro motor 6 is fixedly connected to the bottom of the double-layer filter screen 5, providing power for the movement of scrapers 8. A rotating main shaft 7 is fixedly connected to the output end of the micro motor 6, transmitting power. Two scrapers 8 are fixedly connected to the upper middle part of the outer wall of the rotating main shaft 7, which clean the inner wall and top of the double-layer filter screen 5. The filter screen is cleaned by scraping. A cross-shaped fixing strip 9 is fixedly connected to the top of the inner wall of the dehydration bucket 2, providing support for the annular water box 10. A water tank 13 is fixedly connected to the top right side of the base plate 1, which stores water for cleaning. A high-pressure water pump 14 is fixedly connected to the top of the water tank 13, which can draw water from the water tank 13 and pressurize it. A connecting hose 15 is connected to the top of the high-pressure water pump 14, which transports the pressurized water to the annular water box 10 through the connecting hose 15. The annular water box 10 is fixedly connected to the bottom of the cross-shaped fixing strip 9. 0. The annular water box 10 ensures that the water pressure from multiple high-pressure nozzles 12 is the same. Multiple water outlet hoses 11 are connected to the bottom of the annular water box 10, facilitating the turning of the high-pressure nozzles 12. Each of the multiple water outlet hoses 11 has a fixed connection to a high-pressure nozzle 12 at its bottom. The high-pressure nozzles 12 rinse the inner wall of the dewatering tank 2. A conical base 19 is fixedly connected to the bottom of the dewatering tank 2, reducing impurities remaining inside. An angle adjustment component is provided at the bottom of the cross-shaped fixing bar 9. A conveying mechanism 4 is provided on the inner wall of the conveying pipe 3 for conveying... Mechanism 4 is used for rapid material conveying. The angle adjustment component includes multiple fixing blocks 16. The fixing blocks 16 are used to fix the electric telescopic rod 17 to the bottom of the cross fixing bar 9. The top of the multiple fixing blocks 16 is fixedly connected to the bottom of the cross fixing bar 9. The bottom of the multiple fixing blocks 16 is fixedly connected to the electric telescopic rod 17. The electric telescopic rod 17 enables the high-pressure nozzle 12 to spray water in different directions for rinsing. The bottom end of the multiple electric telescopic rods 17 is fixedly connected to the universal joint 18. The universal joint 18 is connected to the outer wall of the high-pressure nozzle 12 to facilitate the high-pressure nozzle 12 to turn.

[0034] Specifically, the starch mixture is conveyed to the dehydration tank 2 through the conveying pipe 3. Since a double-layer filter screen 5 is fixedly connected to the middle of the inner wall of the dehydration tank 2, the starch mixture reaches the top of the double-layer filter screen 5. The water in the starch mixture is filtered through the double-layer filter screen 5 and flows downwards, while the solid matter is intercepted on the double-layer filter screen 5, thus achieving preliminary solid-liquid separation. After dehydration is completed, the micro motor 6 is started to drive the rotating main shaft 7 to rotate. Two scrapers 8 fixedly connected to the upper part of the outer wall of the rotating main shaft 7 rotate synchronously with the rotating main shaft 7. The scrapers 8 scrape the inner wall and top of the double-layer filter screen 5 to remove residual impurities from the filter screen, preventing impurities from clogging the filter screen and affecting the next dehydration effect. The water tank 13 stores water for cleaning. The high-pressure water pump 14 is started to draw water from the water tank 13 and pressurize it. The pressurized water is transported to the tenth tank through the connecting hose 15. The bottom of the fixed strip 9 is fixedly connected to the annular water box 10. The annular water box 10 can keep the water pressure of multiple high-pressure nozzles 12 the same. Multiple water outlet hoses 11 connected to the bottom of the annular water box 10 deliver water to the high-pressure nozzles 12 fixed at its bottom. The high-pressure nozzles 12 rinse the inner wall of the dehydration bucket 2. When rinsing in different directions is required, the electric telescopic rod 17 is activated, which drives the universal joint 18 fixedly connected at the bottom to move. Since the universal joint 18 is connected to the outer wall of the high-pressure nozzle 12, the high-pressure nozzles 12 can spray water in different directions to ensure that all parts of the inner wall of the dehydration bucket 2 can be cleaned. Since the bottom of the dehydration bucket 2 is fixedly connected to the conical base 19, during the rinsing process, impurities are collected at the bottom of the conical base 19 with the water flow and then discharged from the bottom, reducing the situation of impurities remaining in the dehydration bucket 2.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The conveying mechanism 4 includes a servo motor 401, which provides power for the rotation of the spiral blades 403. The right side of the servo motor 401 is fixedly connected to the left end of the conveying pipe 3. The output end of the servo motor 401 is fixedly connected to a rotating shaft 402, which is used to transmit power. The outer wall of the rotating shaft 402 is fixedly connected to the spiral blades 403, which transport the raw material from a lower position to a higher position. The outer wall of the spiral blades 403 is fixedly connected to multiple stirring teeth 404, which can increase the stirring force of the raw material during transportation. The left end of the outer wall of the conveying pipe 3 is provided with a feed inlet 405, which serves as a component for putting in the raw material. The inner wall of the feed inlet 405 is fixedly connected to a feed basket 406, which facilitates the placement of the raw material. The right end of the outer wall of the conveying pipe 3 is fixedly connected to a guide plate 407, which allows the raw material to fall accurately into the dehydration tank 2.

[0036] Specifically, the operator pours the starch mixture into the feed inlet 405 through the feed basket 406. The feed basket 406 provides a stable placement space for easy raw material feeding. The servo motor 401 is turned on, converting electrical energy into mechanical energy, causing the rotating shaft 402 to start rotating, which in turn drives the spiral blades 403 on the outer wall to rotate synchronously. The spiral blades 403 lift and transport the raw material located at the bottom of the feed basket 406 upwards. During the conveying process, the stirring teeth 404 on the outer wall of the spiral blades 403 continuously stir the raw material, so that the starch mixture is initially stirred during the conveying process, avoiding clumping and accumulation, and making the raw material more uniformly mixed. When the raw material is conveyed to the right end of the conveying pipe 3, the guide plate 407 accurately guides the raw material into the dehydration tank 2, ensuring that the raw material can enter the dehydration tank 2 smoothly and accurately.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A mounting base 20 is fixedly connected to the rear end of the inner wall of the dehydration tank 2. A sonic detector 21 is fixedly connected to the front side of the mounting base 20. The sonic detector 21 is used to detect impurities inside the dehydration tank 2. An observation window 22 is opened at the front end of the outer wall of the dehydration tank 2 to observe the state inside the dehydration tank 2. A fixing frame 23 is fixedly connected to the front side of the observation window 22 to increase the stability of the observation window 22. A limit ring 25 is fixedly connected to the middle of the inner wall of the dehydration tank 2. Multiple limit blocks 26 are fixedly connected to the middle of the inner wall of the dehydration tank 2. The double-layer filter 5 is located between the limiting ring 25 and the limiting block 26, which can increase the stability of the double-layer filter 5 and make it easy to replace the double-layer filter 5 from the upper limiting block 26. The inner wall top of multiple high-pressure nozzles 12 is fixedly connected with sealing rings 24. Multiple sealing rings 24 adopt an annular design. The sealing rings 24 can prevent water from overflowing after pressurization. The top front side of the base plate 1 is fixedly connected to the control console 27. The control console 27 is electrically connected to the micro motor 6, the high-pressure water pump 14, the electric telescopic rod 17 and the acoustic detector 21 respectively.

[0038] Specifically, before the device is put into operation, the operator can connect the device to a specific mobile device via wireless technology. This allows the operator to control the micro motor 6, high-pressure water pump 14, electric telescopic rod 17, and acoustic detector 21 via the control console 27, or remotely via the mobile device. During operation, the acoustic detector 21 detects the presence of impurities inside the dehydration tank 2 by emitting sound waves and receiving reflected waves. The operator can directly observe the internal condition of the dehydration tank 2 through the observation window 22, while the fixing frame 23 ensures the stability of the observation window 22 and prevents damage to the observation window 22 due to vibration. When installing the double-layer filter 5, the double-layer filter 5 is placed under the limiting ring 25. Between the limiting block 26 and the limiting structure, the limiting structure fixes the filter screen from all sides, ensuring that the filter screen remains stable during the dehydration process. When the filter screen needs to be replaced, simply pull out the double-layer filter screen 5 from the top, so that the double-layer filter screen 5 is released from the locking of the limiting ring 25 and the limiting block 26, and the old filter screen can be easily removed and the new filter screen installed. The operation is simple and efficient. After the high-pressure water pump 14 pressurizes the water, the water flows through the annular water box 10 and the water outlet hose 11 to reach the high-pressure nozzle 12. At this time, the annular sealing ring 24 at the top of the inner wall of the high-pressure nozzle 12 tightly fits the connection, and fills the gap with its own elastic deformation to prevent the pressurized water from overflowing, ensuring stable water pressure during the cleaning process and good cleaning effect.

[0039] Working principle: After dehydration is complete, the micro motor 6 is started to drive the rotating main shaft 7 to rotate. The rotating main shaft 7 acts as a power transmission component, causing the two scrapers 8 fixed on the upper part of its outer wall to rotate synchronously. During the rotation, the scrapers 8 contact and scrape against the inner wall and top of the double-layer filter screen 5, removing the impurities remaining on the filter screen and preventing impurities from clogging the filter screen pores, ensuring the permeability of the filter screen so that it can work normally in the next dehydration and maintain the stability of the dehydration effect. After the high-pressure water pump 14 is started, it draws water from the water tank 13 and pressurizes the water. The pressurized water is transported to the annular water box 10 through the connecting hose 15. The annular water box 10 plays a role in evenly distributing the water pressure, ensuring that the water pressure sprayed from the multiple high-pressure nozzles 12 is consistent. The water flows through the outlet hose 11 to the high-pressure nozzle 12, which sprays high-pressure water to rinse the inner wall of the dehydration tank 2, removing dirt and residual starch. When rinsing in different directions is required, the electric telescopic rod 17 extends and retracts, driving the universal joint 18 at the bottom to move. The universal joint 18 has flexible rotation characteristics and is connected to the outer wall of the high-pressure nozzle 12, allowing the high-pressure nozzle 12 to change the spray direction and achieve comprehensive rinsing of all parts of the inner wall of the dehydration tank 2. In addition, the conical base 19 at the bottom of the dehydration tank 2 uses its special shape and structure to guide the impurities and water generated during the rinsing process to the bottom and discharge them from the bottom, reducing the residue of impurities in the dehydration tank 2.

[0040] Furthermore, after the operator starts the servo motor 401, the servo motor 401 provides the power source for the entire material conveying process, driving the rotating shaft 402 to rotate and transmitting the power of the servo motor 401 to the spiral blades 403, enabling the spiral blades 403 to rotate synchronously. The unique spiral structure of the spiral blades 403 forms relative motion with the inner wall of the conveying pipe 3, causing the starch mixture located at the bottom of the feed basket 406 to be lifted and transported upward along the spiral trajectory of the spiral blades 403. Under the push of the spiral blades 403, the material overcomes its own gravity and friction, realizing the movement from a low position to a high position. During the material conveying process, the stirring teeth 404 on the outer wall of the spiral blades 403 continuously contact and stir the starch mixture, breaking up the lumps and accumulation in the starch mixture, so that the raw materials of different components are fully mixed evenly, ensuring that the dehydration process is more uniform and efficient. When the raw material is conveyed to the right end of the conveying pipe 3, the guide plate 407 can guide the raw material to fall accurately into the dehydration tank 2 in a predetermined direction, avoiding the spillage of the raw material.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
