Description

Technical Field

[0001] This utility model relates to the field of particle screening technology, and in particular to a screening device for probiotic-encapsulated particles. Background Technology

[0002] Probiotic encapsulated granules are functional granules in which probiotics are encapsulated in a protective matrix using microencapsulation technology. They are widely used in the food, health product, and pharmaceutical industries. Their production process includes encapsulation, drying, and sieving, with sieving being a key step used to separate granules that meet the particle size requirements, ensuring product quality and consistency.

[0003] In traditional probiotic encapsulated particle sieving processes, single-layer screens are the primary method. While simple in structure, their sieving efficiency is relatively low. Single-layer screens often struggle to achieve uniform sieving when faced with particles of varying sizes, resulting in insufficient particle passage. Furthermore, particles tend to accumulate on the screen surface during sieving, leading to clogging. This clogging not only further reduces sieving efficiency but can also disrupt the continuity of subsequent production processes. In addition, traditional sieving devices face challenges in cleaning and maintenance. Due to the susceptibility to clogging, traditional sieving equipment requires frequent shutdowns for cleaning, causing inconvenience to continuous production and increasing unnecessary downtime and production costs. Adding to the complexity, the intricate structure of the equipment makes cleaning and maintenance even more difficult, further increasing potential future labor and time costs. Therefore, we propose a sieving device for probiotic encapsulated particles. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies. In the traditional process of sieving probiotic encapsulated particles, single-layer screens are the primary method. While simple in structure, their sieving efficiency is relatively low. Single-layer screens often struggle to achieve uniform sieving when faced with particles of varying sizes, resulting in insufficient particle passage. Furthermore, particles tend to accumulate on the screen surface during sieving, leading to clogging. This clogging not only further reduces sieving efficiency but may also affect the continuity of subsequent production processes. In addition, traditional sieving devices face challenges in cleaning and maintenance. Due to the susceptibility to clogging, traditional sieving equipment requires frequent shutdowns for cleaning, causing inconvenience to continuous production and increasing unnecessary downtime and production costs. More complexly, the intricate structure of the equipment makes cleaning and maintenance even more difficult, further increasing potential future labor and time costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sieving device for probiotic encapsulated particles includes a sieving device body, an inlet at the top of the sieving device body, an outlet on one side of the sieving device body near the bottom, an airflow generator installed on one side of the inlet at the top of the sieving device body, the output of the airflow generator extending into the sieving device body and acting on the sieving device body, and a multi-layer sieving device installed inside the sieving device body.

[0007] Furthermore, a first motor is installed at the bottom of the main body of the screening device, and a rotating shaft is installed at the output end of the first motor extending into the main body of the screening device.

[0008] Furthermore, an eccentric wheel drive disk is provided at the top of the rotating shaft, and connecting columns are symmetrically arranged on both sides of the top of the eccentric wheel drive disk, with the connecting columns connected to a multi-layer screening device.

[0009] Furthermore, the multi-layer filtration device consists of several supports and several screens, with the screens placed on the supports.

[0010] Furthermore, the support is a ring support, and a ring of placement blocks is provided at the bottom of the inner wall of the support. Several holes and slots are provided on the placement blocks, and several protrusions are provided at the bottom of the screen, and the protrusions fit into the holes and slots.

[0011] Furthermore, the screen mesh has the largest aperture near the top of the main body of the screening device, and the screen mesh has the smallest aperture near the bottom of the main body of the screening device, at the position of the eccentric wheel drive disc.

[0012] Furthermore, a rotating shaft is symmetrically installed above each of the filter screens, and a placement plate is installed on the side of the main body of the screening device away from the discharge port. Several second motors are installed on the placement plate, and the output ends of the second motors extend into the main body of the screening device and are connected to the rotating shaft.

[0013] Furthermore, a connecting plate is connected to one end of the rotating shaft, and a cleaning brush is installed at the other end of the connecting plate. The height of the cleaning brush is equal to the distance between the rotating shaft and the screen.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model employs a multi-layer filter device, with the filter mesh size gradually decreasing from top to bottom, achieving step-by-step sieving of particles. This design can effectively separate particles of different sizes, significantly improving sieving efficiency, and is especially suitable for probiotic encapsulated particles with a wide particle size distribution. In addition, the filter is driven by an eccentric wheel to generate high-frequency vibration, ensuring that particles are evenly distributed on the screen and pass through the screen quickly, avoiding the problem of uneven sieving in traditional single-layer screens.

[0016] 2. The device is equipped with an automatic cleaning brush system. The cleaning brush is driven by a second motor and moves back and forth along the surface of the filter screen. It can remove the blockage on the screen in time and avoid particle accumulation. The introduction of an airflow generator installed at the top of the device further assists the particles to pass through the screen, reducing particle adhesion and blockage, and ensuring the continuity and stability of the screening process.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a sieving device for probiotic encapsulated particles, including a sieving device body 1, an inlet 101 at the top of the sieving device body 1, an outlet 102 near the bottom on one side of the sieving device body 1, an airflow generator 103 installed on one side of the inlet 101 at the top of the sieving device body 1, the output of the airflow generator 103 extending into the sieving device body 1 and acting on the sieving device body 1, the airflow generator 103 generates a downward airflow to help the particles pass through the screen 202, reducing adhesion and clogging, a multi-layer sieving device 2 is installed inside the sieving device body 1, the multi-layer screen 202 is designed to achieve step-by-step sieving of particles, avoid clogging, and improve sieving efficiency. Example 2

[0027] like Figure 1-4 As shown, a first motor 104 is installed at the bottom of the main body 1 of the screening device. A rotating shaft 105 is installed at the output end of the first motor 104 extending into the main body 1 of the screening device. An eccentric wheel drive disk 106 is provided at the top of the rotating shaft 105. Connecting columns 107 are symmetrically arranged on both sides of the top of the eccentric wheel drive disk 106. The connecting columns 107 are connected to a multi-layer screening device 2. The multi-layer screening device 2 is driven by the eccentric wheel drive disk 106 to generate high-frequency vibration, so that the particles are evenly distributed on the screen 202 and screened step by step. In addition, since the vibration screening method of the eccentric wheel drive disk 106 is designed with low impact force, it reduces mechanical damage to the probiotic-encapsulated particles, protects the integrity of the particles and the activity of the probiotics.

[0028] The multi-layer filtration device 2 consists of several supports 201 and several screens 202. The screens 202 are placed on the supports 201, which are annular supports. A ring of placement blocks 203 is located at the bottom of the inner wall of the supports 201. Several slots 204 are formed on the placement blocks 203. Several protrusions are located at the bottom of the screens 202, and these protrusions fit into the slots 204. The aperture of the screens 202 is largest near the top of the filtration device body 1, and smallest near the bottom of the eccentric wheel drive disc 106. The multi-layer filtration device 2 can flexibly adjust the screen aperture according to different particle size requirements, adapting to various filtration methods. As required, a rotating shaft 108 is symmetrically installed above each screen 202. A placement plate 109 is installed on the side of the main body 1 of the screening device away from the discharge port 102. Several second motors 110 are installed on the placement plate 109. The output end of the second motor 110 extends into the main body 1 of the screening device and is connected to the rotating shaft 108. A connecting plate 111 is connected to one end of the rotating shaft 108. A cleaning brush 112 is installed at the other end of the connecting plate 111. The automatic cleaning brush 112 reduces the frequency of manual cleaning, reduces downtime and maintenance costs, and improves the continuous operation capability of the equipment. The height of the cleaning brush 112 is equal to the distance between the rotating shaft 108 and the screen 202.

[0029] The working process of this utility model is as follows: When using a sieving device for probiotic encapsulated particles, the probiotic encapsulated particles first enter the device through the feed inlet 101 at the top of the sieving device body 1. Then, the airflow generator 103 is activated to generate a downward airflow, which assists the particles in entering the sieving area. After entering the sieving device body 1, the particles first fall onto the uppermost screen 202. The first motor 104 is activated, driving the rotating shaft 105 and the eccentric wheel drive disk 106 to rotate, which drives the multi-layer sieving device 2 to generate high-frequency vibration. The vibration causes the particles to be evenly distributed on the screen 202 and gradually move to the lower screen 202. Under the action of vibration, the particles pass through the screen 202 and enter the lower screen 202 step by step. The aperture of each screen 202 gradually decreases, realizing step-by-step sieving of the particles and ensuring that particles that meet the particle size requirements can pass through the screen 202. At the same time, the airflow generator 103 continuously generates a downward airflow to help the particles pass through the screen 202, reducing the adhesion and clogging of particles on the screen 202 and improving the sieving efficiency.

[0030] During the screening process, the second motor 110 drives the rotating shaft 108 and the connecting plate 111, which in turn drives the cleaning brush 112 to reciprocate along the surface of the screen 202. The cleaning brush 112 removes the blockages on the screen 202 in a timely manner, preventing the screen 202 from becoming clogged and ensuring the continuity and stability of the screening process.

[0031] After being screened step by step by multiple screens 202, particles that meet the particle size requirements finally pass through the bottom screen 202 and fall into the bottom of the main body 1 of the screening device. The particles are discharged from the device through the discharge port 102 near the bottom, thus completing the screening process.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
