Description

Technical Field

[0001] This utility model relates to the field of starch dehydration technology, and in particular to a high-efficiency dehydrator for pea starch. Background Technology

[0002] Pea starch is an important raw material in the food industry, and its dehydration efficiency directly affects the production cycle and product quality. The pea starch dehydration process involves feeding wet starch into a centrifuge, where it is dehydrated under centrifugal force. After dehydration, the starch is separated and collected in a storage tank. Due to the small size and strong adhesion of pea starch particles, they easily adhere to the centrifuge screen during centrifugation, causing screen blockage and reducing production efficiency. To solve the screen blockage problem, existing dehydrators use vibrating screens or mechanical extrusion pretreatment. However, many vibrating screens use low-frequency vibration, which cannot effectively prevent starch accumulation on the screen. While mechanical extrusion pretreatment can reduce the initial moisture content of the starch, it still does not solve the problem of secondary blockage on the screen surface.

[0003] Chinese patent CN 206767981 U discloses a vibrating starch dewatering machine. Depending on actual production needs, the vibration source can be fixed to the bottom plate, side wall, or top of the dewatering machine. The vibration source provides vibration energy, causing starch granules to collide and squeeze out water, thus achieving starch dewatering. While the vibration source can be flexibly installed and is suitable for various scenarios, reducing equipment costs, it primarily uses low-frequency vibration, and this single vibration method cannot effectively solve the problem of screen clogging, easily increasing equipment maintenance costs and affecting production efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a high-efficiency pea starch dehydrator, comprising a cylindrical body with an inlet at the top and an outlet at the bottom. A support is fixedly connected to the bottom surface of the cylinder. The cylinder contains a dehydration component and a self-cleaning component. The dehydration component includes a dehydration cylinder and a rotating motor. The dehydration cylinder is fixedly located in the middle of the inner wall of the cylinder, and the rotating motor is fixedly located in the middle of the bottom end of the cylinder. The dehydration cylinder and the rotating motor are fixedly connected by a rotating shaft. The self-cleaning component is located on the inner wall of the cylinder and is used for reverse blowing of the dehydration cylinder.

[0005] As a further description of this utility model, a self-cleaning component is provided on the inner wall of the cylinder. The self-cleaning component includes a nozzle, a gas collecting hood, and an airflow pipe. The nozzles are evenly distributed along the circumferential direction on the inner wall surface of the cylinder. The nozzles are slender and elongated to facilitate the reverse backflow of residual airflow to sweep the screen holes. The gas collecting hoods are evenly distributed along the circumferential direction on the inner wall surface of the cylinder. The gas collecting hoods are elliptical to facilitate the collection of residual airflow generated during the centrifugation stage. The nozzles and the gas collecting hoods are connected by an airflow pipe. The airflow pipe is located between the inner and outer walls of the cylinder and is spiral in shape. The three components, nozzle, gas collecting hood, and airflow pipe, constitute a closed backflow airflow circulation system.

[0006] As a further description of this utility model, a vibrating plate is fixedly installed at the bottom of the dehydration cylinder to facilitate the generation of high-frequency vibration.

[0007] As a further description of this utility model, the dewatering cylinder is provided with uniformly distributed sieve holes.

[0008] As a further description of this utility model, the surface of the sieve holes is coated with a hydrophobic coating, which can increase the contact angle between the sieve holes and the pea starch and reduce the adhesion of the starch to the surface of the sieve holes.

[0009] As a further description of this utility model, a control panel is fixedly provided on the outside of the cylinder to facilitate the control of the rotating motor and the vibrating plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model innovatively combines high-frequency vibration, hydrophobic coating, and back-blowing airflow pipeline technology, effectively solving the problem of easy screen clogging and significantly improving dewatering efficiency. Specifically, the high-frequency vibration generated by the vibrating plate can effectively promote the loosening of starch granules and reduce the adhesion between granules. The use of a hydrophobic coating on the surface of the screen holes increases the contact angle between the screen holes and pea starch, reducing the adhesion force of starch. The nozzle, air collection hood, and airflow pipeline form a back-blowing airflow pipeline, which utilizes the residual airflow during equipment operation to achieve reverse blowing of the screen holes, ensuring real-time cleaning of starch granules adhering to the screen holes. This equipment accurately controls the three stages of starch granule adhesion: before adhesion, during adhesion, and after adhesion, effectively solving the problem of easy screen clogging in traditional technology and significantly improving the dewatering efficiency of the equipment.

[0012] 2. This utility model adopts a backflush airflow pipeline design, which makes full use of the residual airflow generated during the centrifugation process to self-clean the screen holes. This not only ensures the unobstructed flow of the screen holes, but also improves the cleanliness of the equipment and reduces energy consumption and maintenance costs in the production process.

[0020] The present invention will be described below with reference to examples. The examples are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0021] like Figure 1-3 As shown, this utility model provides a high-efficiency pea starch dehydrator, including a cylindrical body 1. The upper part of the cylindrical body 1 is provided with a feed inlet 11, and the bottom part of the cylindrical body 1 is provided with a discharge outlet 12. A bracket 13 is fixedly connected to the bottom surface of the cylindrical body 1. The interior of the cylindrical body 1 is provided with a dehydration component 2 and a self-cleaning component 3. The dehydration component 2 includes a dehydration cylinder 21 and a rotating motor 22. The dehydration cylinder 21 is fixedly installed in the middle of the inner wall of the cylindrical body 1, and the rotating motor 22 is fixedly installed in the middle of the bottom end of the cylindrical body 1. The dehydration cylinder 21 and the rotating motor 22 are fixedly connected by a rotating shaft 23. The self-cleaning component 3 is installed on the inner wall of the cylindrical body 1 and is used to back-blow and clean the dehydration cylinder 21.

[0022] In this embodiment, a self-cleaning component 3 is provided on the inner wall of the cylinder 1. The self-cleaning component 3 includes a nozzle 31, a gas collecting hood 32, and an airflow pipe 33. The inner wall surface of the cylinder 1 is provided with uniformly distributed nozzles 31 along the circumferential direction. The nozzles 31 are long and thin, which facilitates the backflushing of residual airflow to the screen holes 25. The inner wall surface of the cylinder 1 is provided with uniformly distributed gas collecting hoods 32 along the circumferential direction. The gas collecting hoods 32 are elliptical, which facilitates the collection of airflow generated during the centrifugation stage. The nozzles 31 and the gas collecting hoods 32 are connected by an airflow pipe 33. The airflow pipe 33 is located between the inner and outer walls of the cylinder 1 and is spiral in shape. The spiral airflow pipe design not only increases the length of the airflow path and improves the backflushing efficiency, but also makes the airflow distribution more uniform, which can effectively prevent the screen holes from clogging. The three components of nozzles 31, gas collecting hood 32, and airflow pipe 33 constitute a closed backflushing airflow circulation system to realize the real-time self-cleaning function of the filter screen.

[0023] In this embodiment, a vibrating plate 24 is fixedly installed at the bottom of the dehydration cylinder 21 to facilitate the generation of high-frequency vibration.

[0024] In this embodiment, the dewatering cylinder 21 is provided with uniformly distributed sieve holes 25.

[0025] In this embodiment, the surface of the sieve hole 25 is coated with a hydrophobic coating, which can increase the contact angle between the sieve hole 25 and the pea starch and reduce the adhesion of the starch to the surface of the sieve hole 25.

[0026] In this embodiment, a control panel 14 is fixedly provided on the outside of the cylinder 1 to facilitate the control of the rotating motor 22 and the vibrating plate 24, ensuring the continuity and efficiency of the dehydration process.

[0027] The specific working process of this utility model is as follows: When pea starch enters the dehydrator through the feed inlet 11, the control panel 14 is activated, and the dehydration cylinder 21 begins to rotate at high speed. At the same time, the vibrating plate 24 generates high-frequency vibration to promote the loosening of starch particles. During the centrifugation process, the dehydration cylinder 21 generates a large amount of residual airflow due to high-speed rotation. The air collection hood 32 collects this part of the residual airflow and then transports it to the nozzle 31 through the spiral airflow pipe 33. The airflow at the nozzle 31 blows the sieve hole 25 in the opposite direction to enhance the separation effect between starch particles and sieve hole 25. After the dehydration process is completed, the control panel 14 is turned off, and the dehydrated pea starch is taken out from the discharge port 12.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
