Description

Technical Field

[0001] The utility model relates to the technical field of monosodium glutamate production equipment, in particular to a shaking screen drying device for refined monosodium glutamate. Background Art

[0002] Drying is a crucial step in the production of MSG, directly affecting its final quality and storage stability. Traditional MSG drying methods often rely on natural air drying or simple hot air drying, which have many shortcomings.

[0003] While natural drying is less expensive, it's severely restricted by weather conditions, resulting in low drying efficiency and increased environmental pollution, which can affect the purity of the MSG. Simple hot air drying, on the other hand, often struggles to achieve uniform drying and can easily lead to localized overheating, affecting the MSG's quality. It also consumes relatively high amounts of energy.

[0004] Furthermore, traditional drying equipment often suffers from problems such as screen clogging, uneven drying, and poor sealing during the screening and drying process. These issues not only affect production efficiency but can also lead to contamination of MSG during the drying process, further compromising the final product quality. To address this, we propose a shaking screen drying device for refined MSG. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] The device for drying refined monosodium glutamate by shaking and screening comprises a processing box 1, which is internally mounted with two screens 15 inclined in opposite directions. An upper guide plate 5 and a lower guide plate 3 are respectively mounted on the top and bottom of the processing box 1, both communicating with the interior thereof. Several air pipes 4 connect the upper guide plate 5 and the lower guide plate 3. Each air pipe 4 is mounted with an air pump 40 and a heating box 7. The heating box 7 is fixed to the rear side of the processing box 1. The interior of the heating box 7 is divided into a layer of S-shaped channels by a partition 70, and several equally spaced electric heating meshes 71 are installed within the S-shaped channels. A feed port 13 is defined at the top of the processing box 1, and a discharge port 14 is defined on the outer wall of the processing box 1, located at the lower end of each screen 15. This device achieves effective screening and separation of monosodium glutamate by utilizing the two screens 15 inclined in opposite directions within the processing box 1. Simultaneously, the upper and lower guide plates 5 and 3, along with an air pump 40 and heating box 7 connected by an air pipe 4, force hot air drying on the MSG on the screen 15, improving drying efficiency and uniformity. The S-shaped channel and electric heating grid 71 within the heating box 7 ensure sufficient heating and even distribution of the hot air. The placement of the feed port 13 and discharge port 14 facilitates the addition of raw materials and the discharge of finished products.

[0025] As a preferred feature of this embodiment, a guide plate 10 is fixedly mounted on the outer wall of the processing box 1 below each discharge port 14. A side sealing plate 11 is plugged into and mounted on the top of one end of the guide plate 10 near the discharge port 14. The provision of the guide plate 10 effectively guides the MSG discharged from the discharge port 14, preventing it from scattering or accumulating outside the processing box 1, thereby improving the neatness and efficiency of production.

[0026] As a preferred feature of this embodiment, a material removal opening is defined on the front outer wall of the processing tank 1, near the bottom. A front sealing plate 12 is hingedly mounted to the material removal opening. The top center of the front sealing plate 12 is bolted to the outer wall of the processing tank 1. A support leg 2 is fixedly mounted at each of the four corners of the bottom of the processing tank 1. The design of the material removal opening and front sealing plate 12 allows the operator to easily remove the MSG from the bottom of the processing tank 1. Furthermore, the front sealing plate 12 ensures the sealing of the processing tank 1 during the processing process, preventing the ingress of external impurities.

[0027] As a preferred embodiment of this embodiment, the lower end of the screen 15 is hinged to the processing box 1. Two vibration motors 16 are symmetrically fixedly mounted on the inner wall of the processing box 1 below the upper end of the screen 15. The output shafts of the vibration motors 16 are fixedly connected to the bottom of the screen 15. A motor mounting plate 160 is fixedly mounted on the inner wall of the processing box 1, and the vibration motors 16 are mounted on the motor mounting plate 160. The hinged design of the screen 15 and the processing box 1, and the installation of the vibration motors 16, enable the screen 15 to vibrate when driven by the vibration motors 16, thereby more effectively shaking off the MSG on the screen 15 and improving the screening efficiency and drying effect.

[0028] As a preferred embodiment of the present invention, a feeding hopper 6 is fixedly installed at the feeding port 13 on the top of the processing box 1, and a collecting net is fixedly installed near the bottom of the processing box 1. The setting of the feeding hopper 6 facilitates the continuous addition of a large amount of raw materials and improves production efficiency; the installation of the collecting net facilitates the collection of the filtered MSG.

[0029] As a preferred embodiment of this embodiment, a horizontal plate 30 is fixedly mounted inside the lower guide plate 3. A plurality of fan blades 34 are rotatably mounted on the horizontal plate 30. A driven pulley 31 is coaxially mounted on each fan blade 34. The driven pulley 31 is located below the horizontal plate 30. A driving pulley 32 is rotatably mounted below the horizontal plate 30 and is driven by a belt to the driven pulley 31. A drive motor 33 is fixedly mounted at the bottom of the lower guide plate 3, the output shaft of which is coaxially fixed to the driving pulley 32. The design of the fan blades 34 and the drive motor 33 inside the lower guide plate 3 enables the rotation of the drive motor 33 to drive the fan blades 34, thereby generating airflow, further accelerating the drying process of the monosodium glutamate and improving drying efficiency and uniformity.

[0030] As a preferred embodiment of the present invention, the end of the guide plate 10 away from the discharge port 14 is tilted downward. The tilted design of the end of the guide plate 10 away from the discharge port 14 can ensure that the MSG slides smoothly on the guide plate 10 and is discharged, thereby avoiding accumulation and blockage of the MSG and improving the smoothness and efficiency of production.

[0031] When the utility model's shaking sieve drying device for refined monosodium glutamate is used:

[0032] First, the MSG raw material to be processed is continuously added through the feed port 13 at the top of the processing box 1 or the feed hopper 6. After entering the processing box 1, the raw material falls onto two screens 15 inclined in opposite directions. The design of these two screens 15 allows for better dispersion and separation of the MSG during the screening process, thereby improving screening efficiency.

[0033] Next, the vacuum pump 40 and heating box 7 are activated. The vacuum pump 40 draws air from the processing box 1 through the air pipe 4, creating a negative pressure. Simultaneously, the electric heating grid 71 within the heating box 7 heats the air, generating hot air. This hot air is then transported between the upper and lower guide plates 5 and 3, where it is forced to dry the MSG on the screen 15. The S-shaped channel within the heating box 7 ensures that the hot air is fully heated and evenly distributed within the channel, ensuring uniform and efficient drying.

[0034] During the drying process, the lower end of screen 15 is hinged to processing box 1. Two vibration motors 16 are symmetrically mounted on the inner wall of processing box 1, below the upper end of screen 15. When activated, these vibration motors 16 cause screen 15 to vibrate, effectively shaking off the MSG on screen 15. This vibration not only improves screening efficiency but also further promotes the drying of the MSG.

[0035] After the MSG is fully dried on screen 15, it is discharged through the lower end of screen 15 and onto guide plate 10 fixed below the outer wall of treatment box 1. The design of guide plate 10 effectively guides the MSG discharged from discharge port 14, preventing it from scattering or accumulating outside treatment box 1. Furthermore, a side sealing plate 11 inserted into the top of the end of guide plate 10 near discharge port 14 ensures the sealing of treatment box 1 during the treatment process, preventing the ingress of external impurities.

[0036] In addition, fan blades 34 and a drive motor 33 are also designed inside the lower guide plate 3. When the drive motor 33 is started, it will drive the fan blades 34 to rotate, thereby generating airflow. This airflow further accelerates the drying process of the monosodium glutamate, improving the drying efficiency and uniformity.

[0037] Finally, when the MSG accumulates to a certain level at the bottom of the treatment box 1, the operator can easily remove the MSG through the material removal port and front sealing plate 12, located near the bottom of the front outer wall of the treatment box 1. The design of the front sealing plate 12 not only facilitates the operator's material removal process but also ensures the sealing of the treatment box 1. Furthermore, the support legs 2 fixed at the four corners of the bottom of the treatment box 1 provide stable support for the entire device.

[0038] In summary, the present invention's shake-screen drying device for refined MSG achieves efficient, uniform, and continuous drying of MSG through multiple functions, including screening, vibration, hot air drying, and airflow acceleration. Furthermore, the device boasts a simple structure, easy operation, and high production efficiency, making it highly suitable for widespread application in the MSG production industry.
