Description

Technical Field

[0001] This utility model relates to the field of probiotic production technology, specifically to a powder sieving device for probiotic production. Background Technology

[0002] Probiotics are a class of active microorganisms that colonize the human body and alter the composition of the gut microbiota in a specific part of the host. They promote nutrient absorption and maintain gut health by regulating the host's mucosal and systemic immune functions or by regulating the balance of gut microbiota. Thus, they produce single microorganisms or well-defined mixed microorganisms that are beneficial to the host's health. In the production process of probiotics, powder sieving is a crucial step that directly affects the quality of the final product.

[0003] In existing sieving devices, when sieving probiotic powder, the powder accumulates in the sieve holes under gravity, while impurities tend to accumulate on the sieve plate. Over time, this can cause clogging of the sieve holes, making it impossible to effectively separate the probiotic powder. This not only reduces sieving efficiency but may also damage the sieving equipment. Therefore, this invention proposes a powder sieving device for probiotic production. Utility Model Content

[0004] The purpose of this invention is to provide a powder sieving device for probiotic production, in order to solve the problem mentioned in the background art that when existing sieving devices sieve probiotic powder, the probiotic powder gathers in the sieve holes under the action of gravity, while the sieved impurities often accumulate on the sieve plate. Over time, the sieve holes are prone to blockage, making it impossible to effectively separate the probiotic powder. This not only reduces sieving efficiency but may also damage the sieving equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A powder sieving device for probiotic production includes a frame, a hopper fixedly connected to the top side of the frame, a plurality of rigid springs evenly distributed on the top of the frame about the rear side of the hopper, a support frame fixedly connected to the top of the plurality of rigid springs, a connecting frame fixedly installed on the support frame, and a vibration motor fixedly installed at the bottom of the support frame, an installation plate correspondingly provided on the inner side of the connecting frame, and a sieving screen installed between the two sides of the installation plates, and a plurality of fixing components correspondingly provided on the outer side of the support frame about the connecting frame.

[0007] Optionally, the side of the connecting frame is provided with a discharge plate, and the discharge plate is connected to the inside of the screening screen.

[0008] Optionally, the mounting plates on both sides are provided with a plurality of threaded holes along the plate body direction, and the plurality of threaded holes are provided in correspondence with the fixing components.

[0009] Optionally, a conveyor belt is provided on the side of the frame, and several support columns are linearly distributed at the bottom of the conveyor belt. The conveyor belt is fixedly connected to the outlet end of the discharge plate, and the other end of the conveyor belt is connected to the hopper.

[0010] Optionally, the fixing component includes a support plate, which is correspondingly disposed on the side of the support frame, and the plate body of the support plate is attached to the outer side of the connecting frame. A fixing rod is threaded through the top of the support plate, and the fixing rod passes through a threaded hole to the end face of the bottom of the mounting plate where a nut is threadedly connected.

[0011] Optionally, the bottom of the frame is evenly distributed with foot cups.

[0012] Optionally, the support frame is inclined.

[0013] The beneficial effects of this utility model are:

[0014] This invention employs a vibrating motor to drive a support frame and a sieve screen for vibration. The addition of a rigid spring enhances the vibration effect of the sieve screen, causing the powder to continuously jump and roll on the screen. This more effectively separates particles of different sizes from the probiotic powder. Furthermore, due to the inclined design of the support frame, probiotic powder that fails to pass through the sieve screen moves onto a conveyor belt via a discharge plate and is then transported to a hopper for further sieving via the output belt. Through multiple cyclic sieving processes, the sieving efficiency is improved. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The preferred embodiment of the present invention will be described below.

[0026] Please see Figure 1-5 As shown, the powder sieving device for probiotic production includes a frame 1. A hopper 2 is fixedly connected to the top side of the frame 1. Several rigid springs 3 are evenly distributed on the top of the frame 1 about the rear side of the hopper 2. The rigid springs 3 provide elastic buffering and vibration enhancement during sieving. A support frame 4 is fixedly connected to the top of the several rigid springs 3. A connecting frame 5 is fixedly installed on the support frame 4. A vibration motor 10 is fixedly installed at the bottom of the support frame 4. An installation plate 6 is provided on the inner side of the connecting frame 5. A sieving screen 7 is installed between the two installation plates 6. Several fixing components 8 are provided on the outer side of the support frame 4 about the connecting frame 5.

[0027] Furthermore, a conveyor belt 11 is provided on the side of the frame 1, and several support columns 12 are linearly distributed at the bottom of the conveyor belt 11. The conveyor belt 11 is fixedly connected to the outlet end of the discharge plate 9, and the other end of the conveyor belt 11 is connected to the hopper 2. Foot cups 13 are evenly distributed at the bottom of the frame 1.

[0028] Furthermore, the support frame 4 is set at an angle to ensure that both passed and unpassed probiotic powders move to the next stage.

[0029] Furthermore, the side of the connecting frame 5 is provided with a discharge plate 9, and the discharge plate 9 is connected to the inside of the screening screen 7.

[0030] Furthermore, the mounting plates on both sides 6 are provided with a number of threaded holes 601 along the plate body direction. The threaded holes 601 are correspondingly set with the fixing components 8. Through the cooperation of the threaded holes 601 and the fixing components 8, the screening screen 7 is fixed inside the connecting frame 5.

[0031] Specifically, the probiotic powder is first poured into the hopper 2 for sieving. Then, the vibration motor 10 is started, and the vibration is transmitted to the sieve screen 7 through the elastic action of the support frame 4 and the rigid spring 3. The powder on the sieve screen 7 jumps and rolls continuously under the action of vibration, realizing particle size separation. Larger particles of powder are left on the sieve screen 7, while smaller particles of powder fall into the bottom plate of the connecting frame 5 through the sieve screen 7. Due to the inclined setting of the support frame 4, the sieve screen 7 is also inclined. Therefore, the powder that does not pass through the sieve screen 7 moves to the discharge plate 9. The discharge plate 9 discharges the powder that does not pass through the sieve to the conveyor belt 11. The conveyor belt 11 transports the powder back into the hopper 2. Then, the unqualified probiotic powder is vibrated again to ensure that all powders can meet the required particle size requirements.

[0032] In another embodiment provided by this utility model, such as Figure 3-5 As shown, the fixing component 8 includes a support plate 801, which is correspondingly disposed on the side of the support frame 4, and the plate body of the support plate 801 is attached to the outside of the connecting frame 5. A fixing rod 802 is threaded through the top of the support plate 801, and the fixing rod 802 passes through the threaded hole 601 to the end face of the bottom of the mounting plate 6 and is threadedly connected to a nut 803.

[0033] Specifically, after the fixing rod 802 passes through the threaded hole 601, the nut 803 is tightened at the bottom of the fixing rod 802. The nut 803 also has internal threads that match the external threads of the fixing rod 802. By rotating the nut 803, downward pressure can be generated, which tightly fixes the mounting plate 6, the screening screen 7 and the support plate 801 together. When the vibration motor 10 is started, the support frame 4 and the screening screen 7 will be subjected to strong vibration. However, due to the firm connection of the fixing component 8, the screening screen 7 can remain stable and will not be displaced or loosened due to vibration.

[0034] In use, probiotic powder is poured into hopper 2 for sieving. Then, the vibration motor 10 is started. The vibration generated by the vibration motor 10 is transmitted to the sieving screen 7 through the support frame 4 and rigid spring 3. The rigid spring 3 provides elastic buffering and vibration enhancement during sieving, ensuring that the aperture of the sieving screen 7 is not blocked and that large particles do not collide, thus achieving the best sieving effect. The probiotic powder on the sieving screen 7 jumps and rolls continuously under the action of vibration, achieving particle size separation. Larger particles are left on the sieving screen 7, while smaller particles fall through the sieving screen 7 into the bottom plate of the connecting frame 5. Since both the support frame 4 and the sieving screen 7 are inclined, the powder moves downward along the sieving screen 7 under the action of vibration. Powder that does not pass through the sieving screen 7 moves to the discharge plate 9. 9. Powder that fails to pass the sieve is discharged to the conveyor belt 11, which transports the powder back to the hopper 2 for further sieving. Through multiple cyclic sieving, it can be ensured that all powders meet the required particle size requirements. During the entire sieving process, the fixing component 8 ensures the stability and firmness of the sieve screen 7. After the fixing rod 802 passes through the threaded hole 601, the nut 803 is tightened at the bottom of the fixing rod 802. The nut 803 also has internal threads that match the external threads of the fixing rod 802. By rotating the nut 803, downward pressure can be generated. When the vibration motor 10 is started, although the support frame 4 and the sieve screen 7 will be subjected to strong vibration, the sieve screen 7 can remain stable due to the firm connection of the fixing component 8 and will not be displaced or loosened due to vibration.
