[0002] The processing of wheat starch involves a dehydration step of the starch liquid or starch slurry obtained from the previous process. Existing technology uses a vacuum dehydrator for this step. However, existing vacuum dehydrators require the containerized starch liquid to be lifted into a feeding trough before feeding. Before feeding, the starch liquid is prone to segregation, precipitation, and clumping, which can affect subsequent equipment operation. Therefore, it is necessary to provide a new wheat starch processing dehydration device to solve the above-mentioned technical problems. Utility Model Content

[0005] The feeding assembly includes a feeding hopper and a feeding hood. The feeding hopper is located on one side of the top of the frame, and the feeding hood is installed below the vacuum roller at the top of the frame. A rotating stirring paddle is installed inside the feeding hopper, and a connecting pump is provided at the bottom of the feeding hopper. A connecting pipe is installed between the output end of the connecting pump and the feeding hood.
[0006] The feeding assembly also includes support plates. Two support plates are provided and symmetrically distributed on both sides of the feeding hopper at the top of the frame. A rotating rod is rotatably connected between the two support plates. A bevel gear is meshed between the outer wall of the rotating rod and the stirring paddle.

[0007] Preferably, the vacuum roller has an external mounting groove, and the inside of the mounting groove is provided with symmetrically distributed mounting strips. The bottom of the mounting strips abuts against the inner bottom of the mounting groove. The bottom of the mounting strips is provided with a protruding rod. The bottom end of the protruding rod extends through the mounting groove to the outside of the vacuum roller. A limiting cap is fitted on the outside of the protruding rod, and the top of the limiting cap abuts against the outer wall of the vacuum roller.
[0008] Preferably, each of the two mounting strips has a threaded screw and a sliding guide rod on opposite sides. The ends of the screw and the guide rod in the same mounting strip are provided with the same extrusion plate. The outer wall of the extrusion plate is fixedly connected to the end of the guide rod, and the outer wall of the extrusion plate is rotatably connected to the end of the screw.
[0009] Preferably, the outer wall of the vacuum roller is provided with a filter screen, the filter screen has an open structure at the part opposite to the mounting groove, and the outer wall of the two mounting strips after docking has the same arc shape as the outer wall of the filter screen.

[0012] Preferably, a guide plate is provided on the top side of the frame away from the feeding component, the end of the guide plate near the vacuum roller abuts against the outer wall of the filter cloth, and a collection frame is provided below the guide plate at the top of the frame.
[0013] Compared with related technologies, the wheat starch processing and dehydration device provided by this utility model has the following beneficial effects:
[0014] This invention utilizes a feeding hopper in the feeding assembly to pre-store starch liquid, and a stirring paddle is installed inside the feeding hopper. During operation, the stirring paddle can be driven to rotate synchronously by a rotating vacuum drum, thereby achieving the mixing of the starch slurry. This reduces the phenomenon of segregation, precipitation, and clumping of the starch slurry.
[0015] The utility model uses a transfer pump installed between the feeding hopper and the feeding hood. During use, the transfer pump continuously transports the mixed starch liquid towards the vacuum drum, allowing the transported starch liquid to be adsorbed by the vacuum drum immediately. This further reduces the phenomenon of separation, precipitation, and clumping of starch liquid when it is stored outside the vacuum drum. Therefore, the starch liquid can be more evenly adsorbed and dehydrated by the vacuum drum.
[0016] This utility model uses a compression snap-fit method to install the filter cloth, which makes the transition at the interface of the filter cloth smoother and more even, thus making the scraping and feeding of the dehydrated starch by the guide plate smoother in the later stage.
[0017] This invention uses positioning semi-rings mounted on both sides of a vacuum drum. Once installed, these positioning semi-rings can compress and fix the sides of the filter cloth, making the filter cloth installation more stable and reducing the possibility of the filter cloth shifting during subsequent use.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0025] Please see Figures 1 to 5 The present invention provides a wheat starch processing and dehydration device, which includes: a frame 1, a vacuum roller 11 rotatably connected on the frame 1, a drive motor 12 for driving the vacuum roller 11 on one side of the top of the frame 1, a vacuum pump 13 communicating with the inside of the vacuum roller 11 on the other side of the top of the frame 1, and a feeding assembly 2 on one side of the top of the frame 1.
[0026] In the embodiments of this utility model, please refer to Figures 1 to 5The feeding assembly 2 includes a feeding hopper 21 and a feeding cover 22. The feeding hopper 21 is located on one side of the top of the frame 1, and the feeding cover 22 is mounted below the vacuum roller 11 at the top of the frame 1. A rotating agitator 211 is mounted inside the feeding hopper 21. A connecting pump 24 is located at the bottom of the feeding hopper 21. A connecting pipe 221 is installed between the output end of the connecting pump 24 and the feeding cover 22. The feeding assembly 2 also includes support plates 23. Two support plates 23 are provided and symmetrically distributed on both sides of the feeding hopper 21 at the top of the frame 1. A rotating rod 231 is mounted between the two support plates 23. A bevel gear is meshed between the outer wall of the rotating rod 231 and the agitator 211, and a belt is mounted between the outer wall of the rotating rod 231 and the output shaft of the drive motor 12.
[0027] It should be noted that: the starch liquid is pre-stored in the feeding hopper 21 of the feeding assembly 2, and a stirring paddle 211 is set in the feeding hopper 21. During operation, the rotating rod 231 is driven to rotate synchronously through the belt between the rotating rod 231 and the stirring paddle 211. The rotating rod 231 drives the stirring paddle 211 to rotate synchronously through the bevel gear between the rotating rod 231 and the stirring paddle 211. This can achieve the mixing of the starch slurry, thereby reducing the phenomenon of separation, precipitation and clumping of the starch slurry. In use, the mixed starch liquid is continuously transported towards the vacuum drum 11 by the transfer pump 24, so that the transported starch liquid is adsorbed by the vacuum drum 11 as soon as possible. This can further reduce the phenomenon of separation, precipitation and clumping of the starch liquid when it is concentrated outside the vacuum drum 11. Therefore, the starch liquid can be more evenly adsorbed and dehydrated by the vacuum drum 11.
[0028] In the embodiments of this utility model, please refer to Figures 1 to 5 The vacuum roller 11 has an external mounting groove 112. The interior of the mounting groove 112 is provided with symmetrically distributed mounting strips 4. The bottom of each mounting strip 4 abuts against the inner bottom of the mounting groove 112. A protruding rod 44 is provided at the bottom of each mounting strip 4, with its bottom end extending through the mounting groove 112 to the outside of the vacuum roller 11. A limiting cap 45 is fitted over the protruding rod 44, with its top abutting against the outer wall of the vacuum roller 11. Each of the two mounting strips 4 has a threaded screw 41 and a sliding guide rod 42 on opposite sides. The same mounting strip 4... The ends of the lead screw 41 and the guide rod 42 are provided with the same extrusion plate 43. The outer wall of the extrusion plate 43 is fixedly connected to the end of the guide rod 42, and the outer wall of the extrusion plate 43 is rotatably connected to the end of the lead screw 41. The outer wall of the vacuum roller 11 is provided with a filter screen 111. The filter screen has an open structure at the part opposite to the mounting groove 112, and the outer wall of the two mounting strips 4 after docking has the same arc shape as the outer wall of the filter screen 111. The filter screen 111 is covered with a filter cloth 3, and the two ends of the filter cloth 3 are respectively located in the gap between the two mounting strips 4 and the corresponding extrusion plate 43.
[0029] It should be noted that after installing the filter cloth 3, one end of the filter cloth 3 can be placed between an installation strip 4 and the corresponding extrusion plate 43. Then, the screw 41 can be rotated to move the extrusion plate 43 until the outer walls of the extrusion plate 43 and the installation strip 4 are both against the outer wall of the filter cloth 3. This completes the clamping and fixing of one end of the filter cloth 3. Then, the installation strip 4 can be inserted into the installation groove 112, and the limit cap 45 can be turned to fix the installation strip 4. Then, the vacuum roller 11 can be rotated to wrap the filter cloth 3 around the outside of the filter screen 111. Then, the above steps are repeated to connect the other end of the filter cloth 3 to the installation strip 4, and then fix the installation strip 4. This allows the two installation strips 4 to be joined inside the installation groove. Since the outer wall specifications of the two installation strips 4 after joining are the same as the outer wall specifications of the filter screen 111, the joint of the filter cloth 3 after installation is smoother and flatter. Therefore, the scraping of the dehydrated starch by the guide plate 14 is more stable in the later stage.
[0030] In the embodiments of this utility model, please refer to Figures 1 to 5 The vacuum roller 11 has symmetrically distributed positioning semi-rings 5 on both sides of its exterior. The outer wall of the positioning semi-ring 5 abuts against the outer wall of the filter cloth 3, and the two positioning semi-rings 5 on the same side are fixedly connected by bolts.
[0031] It should be noted that by setting the positioning half-ring 5, when the positioning half-ring 5 is installed on the outer wall of the vacuum drum 11 to clamp and fix the edge of the filter cloth 3, the installation stability of the filter cloth 3 can be improved during subsequent use, and the phenomenon of displacement of the filter cloth 3 on the outer wall of the vacuum drum 11 can be reduced.
[0032] In the embodiments of this utility model, please refer to Figures 1 to 5 A guide plate 14 is mounted on the top of the frame 1 away from the feeding component 2. The end of the guide plate 14 near the vacuum roller 11 abuts against the outer wall of the filter cloth 3, and a collection frame 15 is provided below the guide plate 14 at the top of the frame 1.
[0033] It should be noted that by setting a collection frame 15 below the guide plate 14, when the guide plate 14 abuts against the outer wall of the filter cloth 3 and scrapes off the dehydrated starch, the collection frame 15 can collect the falling starch, which facilitates subsequent processing by the staff.
[0034] The working principle of the wheat starch processing and dehydration device provided by this utility model is as follows:
[0035] When using this device, the operator adds the required dehydrated starch solution into the feeding hopper 21, and then controls the drive motor 12 to drive the vacuum drum 11 to rotate, and at the same time controls the vacuum pump 13 to work.
[0036] While the drive motor 12 is rotating, it will drive the rotating rod 231 to rotate via the belt. The rotating rod 231 will drive the stirring paddle 211 inside the feeding hopper 21 to rotate via the bevel gear. This allows the stirring paddle 211 to stir the starch liquid inside the feeding hopper 21, reducing the phenomenon of separation, precipitation and clumping of the starch liquid inside the feeding hopper 21.
[0037] At the same time, the transfer pump 24 can be controlled to work to input the starch liquid inside the feeding hopper 21 into the feeding hood 22 through the transfer pipe 221. At this time, the starch liquid flowing out from the feeding hood 22 will be adsorbed onto the outer filter cloth 3 by the internal rotating vacuum roller 11. The filter cloth 3 can filter the starch and water in the starch liquid. The filtered water will flow out from the output end of the vacuum pump 13, while the starch will be adsorbed onto the outer wall of the filter cloth 3 due to the suction of the vacuum pump 13.
[0038] When the rotating vacuum drum 11 rotates to the position opposite to the guide plate 14, the guide plate 14, which abuts against the outer wall of the filter cloth 3, will scrape off the starch adsorbed on its outer wall, causing the starch to fall along the guide plate 14 into the collection frame 15 below, thus completing the use of this device.
[0039] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0040] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
