Abstract
Description
Technical Field
[0001] This utility model relates to the field of erythritol production screening technology, specifically to a crystal particle screening device for erythritol production. Background Technology
[0002] Erythritol is a natural sugar and functional sweetener with advantages such as low calorie value, suitability for diabetics, and anti-caries properties. As a novel functional sugar alcohol food sweetener, erythritol is widely found in fruits, algae, fungi, and fermented foods such as soy sauce and wine. It possesses superior properties including high thermal stability, low hygroscopicity, balanced sweetness, zero calorie value, non-cariogenicity, no increase in blood sugar, and high tolerability. It has wide applications in the food, pharmaceutical, and chemical industries, and is particularly competitive in the sweetener market. Furthermore, compared to other sugar alcohol sweeteners, erythritol is currently the only sugar alcohol sweetener produced through microbial fermentation.
[0003] Existing methods for erythritol sieving typically involve directly pouring the erythritol into a sieving mechanism for indirect sieving. However, the simultaneous influx of large quantities of erythritol into the sieving machine leads to uneven sieving, requiring multiple sieving processes—a time-consuming and labor-intensive process that is inconvenient for users. Therefore, there is an urgent need to design a crystal particle sieving device for erythritol production to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a crystal particle screening device for erythritol production, so as to solve the above-mentioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A crystal particle screening device for erythritol production includes a mounting base plate, a support plate mounted on the top of the mounting base plate, a screening box supported on the top of the support plate, a dispersion box mounted on the top of the screening box, a guide box mounted on the top of the dispersion box, a distributing motor mounted on one end of the guide box, a rotating rod mounted on one side of the distributing motor, a guide port opened inside the dispersion box, and a distributing cone installed inside the guide port.
[0007] The screening box is equipped with a first screening plate, a drive motor is installed at one end of the screening box, a motor drive shaft is installed at one end of the drive motor, and a second screening plate is installed at the bottom of the first screening plate.
[0008] Preferably, the material guide box has a storage compartment inside.
[0009] Preferably, the outer wall of the rotating rod is equipped with a material distribution blade.
[0010] Preferably, the bottom end of the distributing cone is fixed with a mounting shaft.
[0011] Preferably, a cam is mounted on the outer wall of the motor drive shaft.
[0012] Preferably, a guide plate is installed at the bottom end of the second screening plate.
[0013] Preferably, a storage box is provided at the top of the support plate.
[0014] Preferably, the bottom of the screening box is provided with a discharge port, and a collection box is placed at the bottom of the discharge port.
[0015] In the above technical solution, the crystal particle screening device for erythritol production provided by this utility model has the following beneficial effects:
[0016] Users pour the erythritol to be screened into the storage hopper at the top of the feed box. When screening is required, the dispensing motor is turned on, causing the rotating rod to drive the dispensing blades inside the storage hopper. This guides the erythritol into the feed inlet of the dispersion box in stages. The dispensing cone inside the feed inlet then disperses the erythritol, preventing a large amount from entering the screening box simultaneously and causing accumulation. After dispersion by the dispensing cone, the erythritol enters the first screening stage inside the screening box. In the process of screening, the drive motor is turned on, causing the motor drive shaft to rotate the cam. The rotation of the cam causes the first screening plate to swing up and down, thereby screening the erythritol on the first screening plate. After the erythritol passes through the first screening plate, it falls down to the top of the second screening plate at the bottom, where it is screened again. The large erythritol particles that are screened out fall into the storage box through the guide plate, while the small erythritol particles fall into the collection box through the discharge port for easy collection.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] like Figure 1-6 As shown in the figure, the erythritol crystal particle screening device provided in this embodiment includes a mounting base plate 1, a support plate 2 mounted on the top of the mounting base plate 1, a screening box 3 supported on the top of the support plate 2, a dispersion box 4 mounted on the top of the screening box 3, a guide box 5 mounted on the top of the dispersion box 4, a distributing motor 6 mounted on one end of the guide box 5, a rotating rod 7 mounted on one side of the distributing motor 6, a guide port 10 opened inside the dispersion box 4, a distributing cone 11 mounted inside the guide port 10, a first screening plate 13 mounted inside the screening box 3, a drive motor 14 mounted on one end of the screening box 3, a motor drive shaft 15 mounted on one end of the drive motor 14, and a second screening plate 17 mounted on the bottom end of the first screening plate 13.
[0027] Specifically, the user pours the erythritol to be screened into the storage bin 9 at the top of the feed box 5. When screening of the erythritol in the storage bin 9 is required, the dispensing motor 6 is turned on, causing the rotating rod 7 to drive the dispensing blades 8 to rotate inside the storage bin 9. This allows the erythritol in the storage bin 9 to be introduced into the feed inlet 10 of the dispersion box 4 in stages. Subsequently, the dispensing cone 11 inside the feed inlet 10 disperses the erythritol, preventing a large amount of erythritol from entering the screening box 3 at the same time and causing accumulation. After being dispersed by the dispensing cone 11, the erythritol enters the first screening plate 1 inside the screening box 3. In step 3, by turning on the drive motor 14, the motor drive shaft 15 drives the cam 16 to rotate. The rotation of the cam 16 causes the first screening plate 13 to swing up and down, thereby achieving the screening of erythritol on the first screening plate 13. After the erythritol passes through the first screening plate 13, it will fall down to the top of the second screening plate 17 at the bottom, and then be screened again by the second screening plate 17. The large erythritol particles that are screened out will fall into the storage box 19 through the guide plate 18, and the small erythritol particles will fall into the collection box 21 through the discharge port 20 for convenient collection.
[0028] In this embodiment, the material guide box 5 has a storage bin 9 inside.
[0029] Specifically, the erythritol to be screened is poured into the storage bin 9 at the top of the feed box 5, which facilitates the screening of erythritol in stages.
[0030] In this embodiment, a material distribution blade 8 is installed on the outer wall of the rotating rod 7.
[0031] Specifically, by turning on the dispensing motor 6, the rotating rod 7 drives the dispensing blades 8 to rotate inside the storage bin 9, thereby introducing the erythritol in the storage bin 9 into the feed inlet 10 in the dispersion box 4 in stages.
[0032] In this embodiment, the bottom end of the material distribution cone 11 is fixed with an installation shaft 12.
[0033] Specifically, the distribution cone 11 is installed inside the dispersion box 4 by the installation shaft 12. The distribution cone 11 disperses the erythritol, preventing a large amount of erythritol from entering the screening box 3 at the same time and causing accumulation.
[0034] In this embodiment, a cam 16 is mounted on the outer wall of the motor drive shaft 15.
[0035] Specifically, by turning on the drive motor 14, the motor drive shaft 15 drives the cam 16 to rotate, and the rotation of the cam 16 will cause the first screening plate 13 to swing up and down.
[0036] In this embodiment, a guide plate 18 is installed at the bottom end of the second screening plate 17.
[0037] Specifically, after erythritol passes through the first sieve plate 13, it falls down to the top of the second sieve plate 17 at the bottom, where it undergoes a second sieve operation.
[0038] In this embodiment, a storage box 19 is provided at the top of the support plate 2.
[0039] Specifically, the large erythritol particles separated by screening will fall into the storage bin 19 through the guide plate 18.
[0040] In this embodiment, a discharge port 20 is provided at the bottom of the screening box 3, and a collection box 21 is placed at the bottom of the discharge port 20.
[0041] Specifically, small particles of erythritol will fall into the collection box 21 through the discharge port 20 for convenient collection.
[0042] Working steps: 1. The user pours the erythritol to be screened into the storage bin 9 at the top of the feed box 5. When the erythritol in the storage bin 9 needs to be screened, the distributing motor 6 can be turned on, so that the rotating rod 7 drives the distributing blade 8 to rotate inside the storage bin 9, thereby introducing the erythritol in the storage bin 9 into the feed inlet 10 in the dispersion box 4 in batches. Then, the distributing cone 11 in the feed inlet 10 disperses the erythritol, avoiding a large amount of erythritol from entering the screening box 3 at the same time and causing accumulation.
[0043] Second, after the erythritol is dispersed by the distributing cone 11, it enters the first screening plate 13 inside the screening box 3. At this time, by turning on the drive motor 14, the motor drive shaft 15 drives the cam 16 to rotate. The rotation of the cam 16 will drive the first screening plate 13 to swing up and down, thereby realizing the screening operation of the erythritol on the first screening plate 13. After the erythritol passes through the screening of the first screening plate 13, it will fall down to the top of the second screening plate 17 at the bottom, and then the second screening plate 17 will perform a second screening operation.
[0044] Third, the large erythritol particles separated by screening will fall into the storage box 19 through the guide plate 18, while the small erythritol particles will fall into the collection box 21 through the discharge port 20 for convenient centralized collection.
[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
