Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of grinding devices, specifically a grinding device for probiotic production. Background Technology
[0002] In the production of probiotics, the grinding precision of raw materials directly affects bacterial activity, product stability, and compatibility with subsequent processes. For example, bacteria, preservatives, and excipients need to be finely ground to achieve uniform mixing, ensuring bacterial survival rate and consistent potency in the finished product during freeze-drying. Traditional grinding equipment often faces the following problems: First, low grinding efficiency, making it difficult to quickly process high-viscosity or fibrous raw materials (such as skim milk powder and sodium alginate); second, coarse particle size control, easily leading to large particle residues or over-grinding generating heat, which can destroy probiotic activity; and third, insufficient equipment sealing, easily introducing impurities or causing dust leakage during grinding, affecting product quality and production environment safety. Therefore, developing a high-efficiency, precise, and airtight grinding device is a key step in improving the stability of probiotic production processes.
[0003] Currently, most probiotic grinding equipment on the market uses traditional stirring or impact grinding structures. Stirring equipment relies on rotating blades to mix materials, but lacks a targeted grinding mechanism, making it particularly difficult to break down bacteria with tough cell walls (such as lactobacilli), resulting in insufficient release of active ingredients. Impact grinding equipment, while achieving finer grinding through high-speed impact, consumes more energy, and localized high temperatures can easily form within the grinding chamber, damaging the activity of heat-sensitive probiotics. Furthermore, the cleaning and maintenance processes for most equipment are complex, and residual materials within the grinding chamber may breed microorganisms, increasing the risk of cross-contamination and failing to meet the hygiene standards required for probiotic production. Summary of the Invention
[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a grinding device for probiotic production, which solves the problems mentioned in the background section.
[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A grinding device for probiotic production includes a grinding cylinder, which is fixedly mounted on a frame. A drive motor is fixedly connected to one side of the grinding cylinder, and a rotating shaft inside the grinding cylinder is fixedly connected to the output end of the drive motor. A spiral blade is fixedly connected to the rotating shaft. A plug is fixedly fitted onto the rotating shaft at the outlet end of the grinding cylinder, and a material hole is opened on the plug. One end of the grinding cylinder is connected to a discharge port. A sealing door is hinged to the top of the grinding cylinder at the discharge port. The other end of the grinding cylinder is connected to a feeding hopper. A U-shaped frame is fixedly mounted on the feeding hopper, and a sliding plate is slidably engaged in the frame. A handle is fixedly connected to one side of the sliding plate.
[0006] Furthermore, the rotating shaft is rotatably connected inside the grinding cylinder via a bearing housing.
[0007] Furthermore, there is a distance between the plug and the grinding cylinder, which connects to the feed port.
[0008] Furthermore, the feed inlet extends below the grinding cylinder, and the bottom of the extended part of the grinding cylinder is provided with a small hole.
[0009] Furthermore, a handle is fixedly connected to the sealed door.
[0010] Furthermore, the skateboard has non-passing tracks on both sides, and the frame has a limiting block inside that engages with the tracks to prevent the skateboard from detaching completely.
[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a grinding device for probiotic production, which has the following beneficial effects: This invention utilizes a combination of spiral blades and a rotating shaft to efficiently push and initially grind materials, improving processing efficiency. A plug combined with a material orifice forms a secondary grinding structure, precisely controlling the output particle size and preventing excessive grinding that could generate heat and damage probiotic activity. A sliding plate and a limiting block allow for dynamic adjustment of the feed rate, preventing blockages. A sealed door and an extended discharge port enhance sealing and ease of cleaning, reducing the risk of contamination and meeting the multiple requirements of probiotic production for precision, activity protection, and hygiene standards.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example like Figure 1-4 As shown in the figure, a grinding device for probiotic production proposed in one embodiment of the present invention includes a grinding cylinder 1. The grinding cylinder 1 is installed and fixed by a frame 2. The frame 2 provides stable support to ensure that the grinding cylinder 1 remains fixed during operation and avoids shaking that affects the grinding effect. A drive motor 3 is fixedly connected to one side of the grinding cylinder 1. The output end of the drive motor 3 is fixedly connected to a rotating shaft 4 inside the grinding cylinder 1. The drive motor 3 provides power to the rotating shaft 4, causing it to rotate at high speed, thereby driving the spiral blades 5 to push and grind the material. The bearing housing ensures smooth rotation of the rotating shaft 4 and reduces frictional loss. The rotating shaft 4 is fixedly connected to a spiral blade 5. When the rotating shaft 4 rotates, the material in the feed hopper 11 is pushed to the outlet end of the grinding cylinder 1. At the same time, the material is ground and stirred through the gap between the blade and the cylinder wall. A plug 6 is fixedly sleeved on the rotating shaft 4 at the outlet end of the grinding cylinder 1. The plug 6 has a material hole 7. The plug 6 prevents the material from being discharged directly from the outlet end, forcing the material to be squeezed out through the material hole 7, thereby achieving secondary grinding and refining. The diameter of the material hole 7 can control the output particle size, ensuring that the material reaches the required grinding precision. One end of the grinding cylinder 1 is connected to the feed port 8. A sealing door 9 is hinged to the upper part of the grinding cylinder 1 at the feed port 8. The sealing door 9 can be opened by the handle 10 to facilitate observation of the internal condition of the grinding cylinder 1 or cleaning and maintenance. When closed, it ensures the sealing of the device. The other end of the grinding cylinder 1 is connected to the feed hopper 11. A U-shaped frame 12 is fixedly installed on the feed hopper 11. A sliding plate 13 is slidably engaged in the frame 12. A handle 16 is fixedly connected to one side of the sliding plate 13. The opening of the feed inlet is adjusted by sliding the sliding plate 13 through the handle 16 to ensure sealing during the processing.
[0016] The working principle of the grinding device for probiotic production is as follows: After the drive motor 3 starts, it drives the rotating shaft 4 to rotate. The spiral blades 5 on the rotating shaft 4 rotate accordingly, pushing the material in the feed hopper 11 into the grinding cylinder 1 through the feed port controlled by the slide plate 13. The material moves towards the outlet end under the pushing and grinding action of the spiral blades 5. When the material reaches the outlet end, it needs to pass through the material hole 7 on the plug 6 to enter the discharge port 8. In this process, the material can be further ground and refined. The small hole at the bottom of the extended part of the discharge port 8 can assist the material to be discharged. If it is necessary to observe or clean during the grinding process, the sealing door 9 can be opened through the handle 10. The slide plate 13 cooperates with the limiting block 15 in the frame 12 through the slide rail 14, and is sealed by pulling the handle 16.
[0017] like Figure 2 As shown, in some embodiments, the rotating shaft 4 is rotatably connected to the inside of the grinding cylinder 1 via a bearing seat; forming a rotatable support structure, the bearing seat provides radial and axial support forces to ensure the coaxiality of the rotating shaft 4 and the grinding cylinder 1.
[0018] like Figure 2 As shown, in some embodiments, there is a distance between the plug 6 and the grinding cylinder 1, which is connected to the feed port 8; the plug 6 prevents the material from being discharged quickly from the outlet end of the grinding cylinder 1, forcing the material to be repeatedly pushed and ground by the spiral blades 5 inside the grinding cylinder 1, extending the residence time of the material in the cylinder, and ensuring sufficient grinding.
[0019] like Figure 2 As shown, in some embodiments, the discharge port 8 extends below the grinding cylinder 1, and the bottom of the extended part of the grinding cylinder 1 is provided with a small hole; the extended discharge port 8 can directly connect to the discharge port 8 below, shortening the transmission distance between devices and improving the continuity of the production process; the dispersing effect of the small hole at the bottom also facilitates the material to fall evenly into the discharge port 8, improving the overall production efficiency.
[0020] like Figure 1 As shown, in some embodiments, a handle 10 is fixedly connected to the sealing door 9; the shape and position of the handle 10 conform to ergonomic design, avoiding direct contact between the operator and any sharp parts or high-temperature surfaces that may exist on the edge of the sealing door 9, thereby reducing fatigue and safety risks during operation.
[0021] like Figure 4 As shown, in some embodiments, the slide plate 13 is provided with non-passing slide rails 14 on both sides, and the frame 12 is provided with limiting blocks 15 that engage with the slide rails 14. The limiting blocks 15 are used to prevent the slide plate 13 from completely disengaging. The guiding function of the slide rails 14 enables the slide plate 13 to move along a fixed path when it is opened or closed. The operator can easily reset it to the initial position by pulling the handle 16, reducing the difficulty of operation and improving maintenance efficiency.
[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
