A hopper cover is hinged to the top of the feed hopper, and an auxiliary handle is located on the top of the hopper cover. A discharge port is located on the lower left side of the device box and is connected to the device box. An air inlet is located on the rear side of the device box, corresponding to the first, second, and third inclined plates. Air guide hoods are located on the rear side of the device box, corresponding to the air inlets. Connecting pipes connect the air guide hoods, and a duct is connected to the rear side of the middle air guide hood. A door is hinged to the front side of the device box. This iron removal device absorbs the iron contained in the particles by using magnetic plates.

[0004] During the use of the iron removal device disclosed in the aforementioned utility model patent, iron is adsorbed onto the magnetic plate. When the iron impurities on the magnetic plate accumulate to a certain amount, the device needs to be stopped and the magnetic plate cleaned, which is time-consuming and labor-intensive, and also leads to a reduction in processing efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an iron removal device for rice protein processing, which solves the problem of time-consuming and labor-intensive shutdown for cleaning of existing iron removal devices.

[0006] According to an embodiment of this utility model, an iron removal device for rice protein processing includes a box body. The top of the box body is provided with a feed inlet, and the bottom of the box body is provided with a first discharge port and a second discharge port spaced apart. The box body is provided with a guide hopper and a screening hopper. The feed inlet, the guide hopper, the screening hopper and the first discharge port are connected in sequence. The screening hopper is provided with a rotatable rotating frame and a drive assembly that is pultrusively connected to the rotating frame. An iron removal plate is rotatably connected to the rotating frame, and the screening hopper is provided with a groove for accommodating the iron removal plate. When the drive assembly drives the rotating frame to rotate, the iron removal plate enters or exits the groove. When the iron removal plate enters the groove, it is flush with the inner wall of the screening hopper. When the iron removal plate exits the groove, it moves to above the second discharge port. An electromagnet is provided on the iron removal plate.

[0007] Furthermore, the housing is also equipped with a feeding hopper, which is connected to the feeding port.

[0008] Furthermore, the guide hopper has a guide port on the side near the screen hopper, the screen hopper has a limiting plate and the limiting plate and the screen hopper form a screening channel communicating with the guide port, and the end of the screening channel away from the guide port is located above the groove.

[0009] Furthermore, the width of the screening channel gradually decreases in the direction away from the feed inlet.

[0010] Furthermore, the drive assembly includes a piston rod disposed at the output end of the cylinder, the cylinder being rotatably connected to the screen hopper, and the piston rod being rotatably connected to the rotating frame.

[0011] Furthermore, the iron removal plate is provided with multiple vertical baffles, which are arranged alternately on the iron removal plate.

[0012] Furthermore, the iron removal plate is equipped with a vibration motor, which is fixedly connected to the iron removal plate.

[0013] Furthermore, the housing is also provided with a discharge hopper that communicates with the second discharge port, and the discharge hopper extends away from the first discharge port.

[0014] Furthermore, the housing is also provided with an observation window, which is located on one side of the screen hopper.

[0015] Compared with existing technologies, this utility model has the following advantages: By using a guide hopper and a screening hopper set inside the box to screen rice, the rice is poured into the box from the inlet and enters the guide hopper, and is conveyed to the screening hopper. When the rice moves in the screening hopper, it passes above the iron removal plate. The iron impurities in the rice are attracted by the electromagnet on the iron removal plate, while the rice continues to move along the screening hopper and falls into the first discharge port to be discharged from the box, thus separating the iron impurities in the rice. After all the rice in the box is discharged, the operating drive component drives the rotating frame to rotate, causing the iron removal plate to exit the groove and move above the second discharge port. At this time, the electromagnet is turned off, allowing the iron impurities remaining on the iron removal plate to slide down the iron removal plate and be discharged from the second discharge port, thereby automatically cleaning the iron removal plate. This solves the technical problem of the time-consuming and labor-intensive process of cleaning existing iron removal devices by stopping the machine, and produces the technical effect of automatically discharging the iron impurities screened from the rice. The operation is simple and convenient, which is conducive to improving processing efficiency. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes an iron removal device for rice protein processing, which is used to remove iron impurities from the raw rice during the production of rice enzymatic protein powder.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the iron removal device for rice protein processing includes a housing 1. The top of the housing 1 has an inlet 11, and the bottom of the housing 1 has a first discharge port 12 and a second discharge port 13 spaced apart. The housing 1 contains a guide hopper 2 and a sieve hopper 3. The inlet 11, the guide hopper 2, the sieve hopper 3, and the first discharge port 12 are sequentially connected. Rice to be iron removed is poured into the housing 1 through the inlet 11 and moves sequentially along the guide hopper 2 and the sieve hopper 3, and is discharged through the first discharge port 12. The sieve hopper 3 has a rotatable rotating frame 4 and a drive assembly 5 connected to the rotating frame 4. An iron removal plate 6 is rotatably connected to the rotating frame 4, and the sieve hopper 3 has a groove 31 for accommodating the iron removal plate 6. When the drive assembly 5 drives the rotating frame 4 to rotate, the iron removal plate 6 enters or exits the groove 31. The iron removal plate 6 enters the groove 31 and is flush with the inner wall of the sieve hopper 3. When the iron removal plate 6 exits the groove 31, it moves to the top of the second discharge port 13. The iron removal plate 6 is equipped with an electromagnet 61. When the iron removal plate 6 is located in the groove 31, the electromagnet 61 is turned on to adsorb iron impurities in the rice passing through the sieve hopper 3. The iron-removed rice is discharged from the first discharge port 12, while the iron impurities are adsorbed on the iron removal plate 6. When the iron removal plate 6 needs to be cleaned, the drive assembly 5 drives the rotating frame 4 to rotate so that the iron removal plate 6 exits the groove 31 and moves to the top of the second discharge port 13. At this time, the electromagnet 61 is turned off so that the iron impurities slide down the iron removal plate 6 and are discharged from the second discharge port 13, thereby cleaning the iron removal plate 6.

[0021] Specifically, the working process of the iron removal device for rice protein processing provided in this embodiment is as follows: First, confirm the position of the iron removal plate 6, operate the drive assembly 5 to drive the rotating frame 4 to rotate and move the iron removal plate 6 into the groove 31, and turn on the electromagnet 61. Pour the rice to be iron removed into the box 1 from the feed inlet 11. The rice enters the guide hopper 2 and is conveyed along the guide hopper 2 to the screen hopper 3. When the rice moves in the screen hopper 3, it passes over the upper ball on the iron removal plate 6, and the iron impurities in the rice are adsorbed by the electromagnet 61, while the rice continues to move along the screen hopper 3. The rice falls into the first discharge port 12 and is discharged from the box 1, thereby separating the iron impurities in the rice. After all the rice in the box 1 has been discharged, when it is necessary to clean the iron removal plate 6, first operate the drive component 5 to drive the rotating frame 4 to rotate, causing the iron removal plate 6 to exit the groove 31 and move above the second discharge port 13. Then turn off the electromagnet 61. At this time, the electromagnet 61 no longer attracts the iron impurities retained on the iron removal plate 6, allowing the iron impurities to slide down the iron removal plate 6 and be discharged from the second discharge port 13, thus automatically removing the iron impurities on the iron removal plate 6. The iron removal device for rice protein processing provided in this embodiment can automatically discharge the iron impurities screened from the rice. It is simple and convenient to operate and helps to improve processing efficiency.

[0022] like Figure 1 As shown, the housing 1 is also equipped with a feeding hopper 14, which is connected to the feeding port 11. The feeding hopper 14 is used to guide the rice through the feeding port 11 during the process of pouring rice into the housing 1, preventing the rice from falling outside the feeding port 11 and causing material loss, thereby facilitating the use of the iron removal device for rice protein processing.

[0023] Please combine Figure 2 and Figure 3 The feed hopper 2 has a feed inlet 21 on the side near the sieve hopper 3. The sieve hopper 3 has a limiting plate 32, and the limiting plate 32 and the sieve hopper 3 form a sieve channel 33 communicating with the feed inlet 21. The end of the sieve channel 33 away from the feed inlet 21 is located above the groove 31. The limiting plate 32 on the sieve hopper 3 is used to guide the rice falling from the feed inlet 21 to move towards the iron removal plate 6 in the groove 31, ensuring that the rice entering the sieve hopper 3 is in stable contact with the iron removal plate 6, which is beneficial to improving the iron removal effect of the iron removal device for rice protein processing.

[0024] In this embodiment, the width of the screening channel 33 gradually decreases in the direction away from the feed inlet 21. Setting the width of the screening channel 33 to gradually decrease in the direction away from the feed inlet 21 allows the rice to be spread evenly on the iron removal plate 6 and prevents the rice from being too thick on the iron removal plate 6, which would prevent iron impurities mixed in the rice from being attracted by the electromagnet 61, thus ensuring that the iron removal device for rice protein processing can effectively remove iron impurities from the rice.

[0025] like Figure 3 and Figure 4 As shown, the drive assembly 5 includes a cylinder 51 and a piston rod 52 disposed at the output end of the cylinder 51. The cylinder 51 is rotatably connected to the screen hopper 3, and the piston rod 52 is rotatably connected to the rotating frame 4. The rotating frame 4 can be controlled by the cylinder 51 driving the piston rod 52 to extend or retract. When the piston rod 52 extends from the cylinder 51, it pushes the rotating frame 4 to rotate and moves the iron removal plate 6 into the groove 31. When the piston rod 52 retracts from the cylinder 51, it pulls the rotating frame 4 to rotate and moves the iron removal plate 6 out of the groove 31. That is, the position of the iron removal plate 6 can be easily adjusted by controlling the cylinder 51.

[0026] In detail, the iron removal plate 6 is provided with multiple vertical baffles 62, which are staggered on the iron removal plate 6. By staggering the multiple vertical baffles 62 on the iron removal plate 6, the rice is prevented from sliding on the iron removal plate 6, thereby slowing down the movement speed of the rice on the iron removal plate 6 and increasing the retention time of the rice. This ensures that the electromagnet 61 can fully adsorb the iron impurities in the rice, further improving the iron removal effect of the iron removal device for rice protein processing.

[0027] Please refer to Figure 4 The iron removal plate 6 is equipped with a vibration motor 63, which is fixedly connected to the iron removal plate 6. When cleaning the iron removal plate 6, the rotating frame 4 moves the iron removal plate 6 to above the second discharge port 13 and then turns on the vibration motor 63. The vibration motor 63 drives the iron removal plate 6 to vibrate, which can quickly remove iron impurities stuck on the iron removal plate 6, ensuring that the iron removal plate 6 is cleaned. In addition, the vibration motor 63 can also drive the iron removal plate 6 to vibrate during the iron removal process of rice, preventing rice from accumulating on the iron removal plate 6 and causing blockage.

[0028] like Figure 2 and Figure 3As shown, the box body 1 is also provided with a discharge hopper 15 communicating with the second discharge port 13. The discharge hopper 15 extends away from the first discharge port 12. The discharge hopper 15 is used to guide iron impurities out of the box body 1 from the second discharge port 13, and the discharge hopper 15 guides the iron impurities to fall away from the first discharge port 12, so as to avoid iron impurities falling into the cleaned rice and causing pollution during the cleaning process.

[0029] In this embodiment, the housing 1 is also provided with an observation window 16, which is located on one side of the sieve hopper 3. The observation window 16 is used to observe the interior of the housing 1 so as to confirm that all the rice in the housing 1 has been discharged before cleaning the iron removal plate 6.

[0030] like Figure 1 As shown, the housing 1 is also equipped with a main controller, and the cylinder 51, the electromagnet 61, and the vibration motor 63 are electrically connected to the main controller. The main controller can control the switching or operation of the cylinder 51, the electromagnet 61, and the vibration motor 63, thereby facilitating the operation of the iron removal device for rice protein processing.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
