Description

Technical Field

[0001] The embodiments of the present invention relate to the field of pulverizing apparatus technology, and more specifically, to a pulverizing apparatus for processing dietary fiber. Background Technology

[0002] Dietary fiber mainly comes from different substances, and different types of substances have different emphases in its content and type. In the production process, it needs to go through a series of steps such as washing, peeling, drying and pulverizing to obtain the subsequent products. In the pulverizing process, a pulverizing device is required.

[0003] Currently, commonly used crushing devices include a cylinder and a support for fixing the cylinder, as well as a conical component that rotates at the bottom inside the cylinder with its tip pointing upwards. A baffle plate is fixed on the inner wall of the cylinder. After the conical component rotates, the raw material is blocked by the baffle plate and can quickly rub and squeeze against the outer wall of the cone and the inner wall of the cylinder, thereby achieving the crushing operation.

[0004] However, the above-mentioned crushing device still has the following drawbacks: when the cone part of the crushing device stops rotating and is ready to discharge material, the "gate" at the bottom of the cylinder is usually opened, or the subsequent product is directly taken out from the top of the cylinder. The above-mentioned discharge methods are prone to causing residue inside the cylinder. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a pulverizing device for dietary fiber processing, which solves the technical problem in the related art where, when the internal conical component of the pulverizing device stops rotating and feeds material, the method of opening the "gate" at the bottom of the cylinder or scooping the material from the top of the cylinder easily causes product residue inside the cylinder.

[0006] According to one aspect, at least one embodiment of the present invention provides a pulverizing apparatus for processing dietary fiber, comprising: The grinding cylinder has several baffles on its inner bottom wall and several discharge ports. A conical crushing disc is rotatably disposed at the bottom of the crushing cylinder, with the tip of the conical crushing disc facing upward and located inside the crushing cylinder. Each of the blocking plates forms a material passage gap with the outer wall of the conical crushing disc, and a plurality of discharge ports are arranged around the conical crushing disc. A discharge cylinder for blocking the discharge ports is sleeved on the outer peripheral wall of the crushing cylinder, and the discharge cylinder and the crushing cylinder are slidably engaged. The conical crushing disc rotates and drives the raw material to revolve until it is blocked by the blocking plate, so that the raw material rolls at the blocking plate to be crushed, and the crushed product passes through the material passage gap. After the discharge cylinder rises, it can open the discharge port, so that the crushed product in the crushing cylinder can be discharged from the discharge port.

[0007] For example, at least one embodiment of the present invention provides a pulverizing device for processing dietary fiber, wherein the bottom wall of the pulverizing cylinder is further provided with an annular receiving groove, the inner wall of the annular receiving groove and the outer wall of the pulverizing cylinder forming a receiving annular groove for receiving products discharged from the outlet.

[0008] For example, at least one embodiment of the present invention provides a pulverizing device for processing dietary fiber, wherein a collection port is provided on the side wall of the annular receiving trough, and the bottom height of the annular receiving trough gradually decreases along the direction close to the collection port.

[0009] For example, at least one embodiment of the present invention provides a grinding device for processing dietary fiber, wherein the grinding cylinder is cylindrical, and a plurality of the blocking plates are arranged around the conical grinding disc and are all inclined.

[0010] For example, at least one embodiment of the present invention provides a pulverizing device for processing dietary fiber, wherein there are two blocking plates, and the two blocking plates are centrally symmetrically distributed; The inner wall of the crushing cylinder has two vertical grooves, and the two blocking plates are respectively interference-fitted into the two vertical grooves to adjust the height of the blocking plates.

[0011] For example, at least one embodiment of the present invention provides a grinding device for processing dietary fiber, wherein the inner wall of the grinding cylinder is further provided with two vertical grooves, and further includes: The cleaning scraper has two ends that are respectively interference-fitted into the two vertical grooves. The cleaning scraper is inverted V-shaped and fits against the outer wall of the conical crushing disc. Wherein, after the conical crushing disc rotates, the cleaning scraper can scrape off the product on the outer wall of the conical crushing disc.

[0012] For example, at least one embodiment of the present invention provides a pulverizing apparatus for processing dietary fiber, which further includes: The motor is embedded in the bottom of the crushing cylinder and is connected to the center of the conical crushing disc for transmission. The motor is used to drive the conical crushing disc to rotate.

[0013] For example, at least one embodiment of the present invention provides a pulverizing device for processing dietary fiber, wherein the bottom of the pulverizing cylinder is detachably provided with a mounting base, the conical pulverizing disc is rotatably mounted on the mounting base, and the mounting base is equipped with a motor for driving the conical pulverizing disc to rotate.

[0014] For example, at least one embodiment of the present invention provides a pulverizing device for processing dietary fiber, wherein the outer wall of the conical pulverizing disc is provided with a plurality of material-pushing protrusions, the plurality of material-pushing protrusions are arranged along the circumference, and the material-pushing protrusions are used to drive the raw material to rotate.

[0015] For example, at least one embodiment of the present invention provides a pulverizing device for processing dietary fiber, wherein the cross-section of the feeding protrusion is triangular, trapezoidal, or semi-circular.

[0016] The beneficial effects of the embodiments of the present invention are as follows: This crushing device has several discharge ports on the bottom wall of the crushing cylinder, and a sliding discharge cylinder is fitted around the outer periphery of the crushing cylinder. When the conical crushing disc stops rotating, the sliding discharge cylinder is raised to open the discharge ports. At this time, the crushed product can be discharged from the multiple discharge ports arranged around the conical crushing disc under its own weight and a certain centrifugal force, avoiding the material residue in the cylinder when the traditional "gate" only discharges material from a single position or scoops it from above (multiple discharge ports can cover the material accumulation area around the conical crushing disc, allowing the material to be discharged more thoroughly and in a timely manner). Furthermore, the opening and closing of the discharge ports can be precisely controlled by controlling the raising and lowering of the discharge cylinder to ensure that the material in the crushing chamber is fully crushed. After crushing is completed, the discharge ports are opened to achieve rapid material discharge, making the operation flexible and controllable.

[0017] Furthermore, the material passing through the barrier plates and the outer wall of the cone crushing disc forms several gaps, allowing the material to be simultaneously pulverized by friction and compression in multiple areas after being blocked. This covers most of the cone crushing disc, significantly improving pulverization efficiency compared to the single pulverization area of ​​traditional devices, and enabling the processing of more materials at the same time. Moreover, the design of the material passing through gaps can be adjusted according to the hardness and toughness of different dietary fibers (e.g., by changing the cone crushing disc with different cone angles or adjusting the position of the barrier plates), thus adapting to the pulverization needs of various materials such as oat fiber, fruit and vegetable fiber, or fungal and algal fiber, making it widely applicable.

[0027] like Figures 1-4 As shown, this invention illustrates a dietary fiber processing pulverizing device according to an embodiment of the present invention. It includes a pulverizing cylinder 1, which is cylindrical and serves as the main housing component of the entire pulverizing device. The entire device is resting on the ground via a steel structure support at the bottom. Several baffle plates 101 are integrally formed, welded, or bolted to the bottom perimeter of the inner wall of the pulverizing cylinder 1. The baffle plates 101 can be rectangular, triangular, or prismatic, and their length extends towards the center of the pulverizing cylinder 1. Several discharge ports 102 are also provided around the bottom perimeter of the inner wall of the pulverizing cylinder 1. The discharge ports 102 are rectangular, circular, or oblong holes. A conical pulverizing disc 2 is a conical disc with its tip pointing upwards. It is rotatably positioned at the bottom center of the pulverizing cylinder 1, and its rotational power can be provided by a motor or transmission mechanism at the bottom (specifically, such as...). Figure 3As shown, the cylindrical component at the bottom represents the motor, which is bolted to the steel structure support at the bottom and is connected to the central drive of the conical grinding disc 2, thus directly driving the conical grinding disc 2 to rotate. A material passage gap 3 is formed between its outer wall and each blocking plate 101. The gap width can be adjusted according to the particle size requirements of the dietary fiber to be ground (e.g., by replacing the conical grinding disc 2 with a different taper or adjusting the height of the blocking plate 101). The discharge cylinder 4 is also cylindrical, with an inner diameter larger than the outer diameter of the grinding cylinder 1, and is fitted onto the outer peripheral wall of the grinding cylinder 1. The length of the discharge cylinder 4 is equal to or greater than the length of the grinding cylinder 1, thus covering the discharge port 102 on the grinding cylinder 1. The discharge cylinder 4 and the grinding cylinder 1 slide and move up and down along the outer wall of the grinding cylinder 1 under the action of external force, thereby blocking or opening the discharge port 102.

[0028] Regarding the transmission mechanism of the conical crushing disc 2, a mounting base can be detachably installed at the bottom of the crushing cylinder 1. The mounting base can be cylindrical, and the conical crushing disc 2 is rotatably mounted on the top surface of the mounting base. A motor for driving the conical crushing disc 2 to rotate is installed inside the mounting base. The motor is also connected to the center of the conical crushing disc 2 for transmission, so that the conical crushing disc 2 can be directly driven to rotate. The advantage of this is that when the conical crushing disc 2 inside the crushing cylinder 1 is covered with impurities that have been left over from long-term operation and are difficult to clean, and the conical crushing disc 2 needs to be replaced, the blocking plate 101 can be removed directly and the mounting base can be removed, or the entire mounting base can be removed directly from the bottom of the crushing cylinder 1 to achieve the purpose of replacement.

[0029] Overall working principle: First, the cone crushing disc 2 rotates under the drive of the motor, causing the dietary fiber raw material fed into the crushing cylinder 1 to revolve (for lighter dietary fiber raw materials, to avoid poor revolve effect, a high-friction material such as a rubber layer can be attached to the outer peripheral wall of the cone crushing disc 2). During the revolve of the cone crushing disc 2, the raw material is blocked by the baffle plate 101 on the inner bottom wall. At this time, the raw material rolls, rubs, and is squeezed at the baffle plate 101, thus being crushed. The crushed product fragments can pass through the material passage gap 3 between the baffle plate 101 and the outer wall of the cone crushing disc 2 one after another, resulting in the final crushed product. During this stage, the discharge cylinder 4 is always in a low position and is supported by the steel structure support at the bottom of the crushing cylinder 1, which blocks the discharge port 102 to ensure that the raw material is fully crushed in the crushing cylinder 1. When the crushing is completed and the material needs to be discharged, the conical crushing disc 2 stops rotating. At this time, the discharge cylinder 4 is slid upward by hand to open the discharge port 102 arranged around the conical crushing disc 2. The crushed product is discharged from the discharge port 102 under its own weight, completing the feeding process. (To further facilitate rapid discharge, the conical crushing disc 2 can be restarted, and the product will be discharged from the discharge port 102 under its own weight and a certain centrifugal force.)

[0030] As a further implementation method, such asFigure 5 As shown, an annular receiving trough 5 is integrally formed or welded on the outer bottom wall of the crushing cylinder 1. Its cross-section is L-shaped so that the inner wall of the annular receiving trough 5 and the outer wall of the crushing cylinder 1 can form a receiving ring groove 501 for receiving the product discharged from the discharge port 102. As the bottom height of the annular receiving trough 5 gradually decreases along the first direction, that is, the direction close to the collection port 502 on the side wall of the annular receiving trough 5, the product fragments discharged from the discharge port 102 can be uniformly recycled into the receiving ring groove 501 and discharged from the collection port 502 under its own weight, which is convenient for quick recycling into the packaging bag.

[0031] As a further implementation method, such as Figure 2 , Figure 3 As shown, several blocking plates 101 are arranged around the conical crushing disc 2 and are all inclined. There can be two blocking plates 101, and the two blocking plates 101 need to be centrally symmetrically distributed so that after the conical crushing disc 2 rotates, each inclined blocking plate 101 can play a blocking role to prevent the raw material from being stuck in the material passage gap 3 or directly passing over the blocking plate 101.

[0032] As a parallel implementation method, the blocking plates 101 can also be implemented in other alternative ways. For example, in terms of quantity and distribution: three or four blocking plates 101 can be set and evenly arranged at equal angles around the conical crushing disc 2, so that the raw material can be evenly blocked by multiple blocking plates 101 in the circumferential direction, further improving the uniformity of crushing and avoiding local accumulation of raw material; or an asymmetrical distribution can be adopted, when the number of blocking plates 101 is three or more, the included angles between the three blocking plates 101 are 100°, 120° and 140° respectively. This distribution can break the regularity of the movement of raw material, making the movement of raw material in the crushing cylinder 1 more random, increasing the probability of contact with the conical crushing disc 2 and the blocking plates 101, and improving the crushing efficiency; or in terms of structure: the blocking plates 101 are generally arc-shaped, and their concave surfaces face the rotation direction of the conical crushing disc 2. The arc-shaped structure can form a "wrap-like" barrier for the raw materials, causing them to roll and rub within the arc surface. This not only crushes the raw materials but also guides them, allowing the crushed product to pass through the material passage gap 3 more smoothly. This is suitable for softer fibers. Alternatively, a stepped barrier plate 101 can be used. The barrier plate 101 is set in a stepped shape along the height direction, with different heights for each step. When the raw materials are blocked, they will be crushed at different heights of the steps, thus achieving multi-level crushing of the raw materials. This is suitable for complex fiber structures such as algae and fungi fibers, such as kelp fibers.

[0033] Furthermore, the barrier plate 101 can be connected to the inner bottom wall of the grinding cylinder 1 using a conventional bolt connection method. This allows for easy replacement of barrier plates 101 of different shapes and sizes according to the grinding requirements of different dietary fibers. Alternatively, an angle adjustment mechanism, such as a hinge and bolt locking structure, can be added at the connection between the barrier plate 101 and the inner bottom wall of the grinding cylinder 1. By adjusting the tilt angle of the barrier plate 101, the width and shape of the material passage gap 3 can be changed to adapt to the grinding of dietary fibers with different particle size requirements, thereby improving the versatility of the device.

[0034] As a further implementation method, such as Figure 6 , Figure 7 As shown, two symmetrical vertical grooves 103 are opened on the inner wall of the crushing cylinder 1. Two blocking plates 101 are respectively interference-fitted into the two vertical grooves 103, so that the height of the blocking plates 101 can be adjusted in advance. Specifically, the end of the blocking plate 101 away from the center of the crushing cylinder 1 is welded or integrally formed with a plug-in block, which is interference-fitted into the vertical groove 103.

[0035] As a further implementation, to facilitate regular cleaning of the inside of the grinding cylinder 1, in addition to using water treatment, it is also necessary to scrape the outer peripheral wall of the conical grinding disc 2. Therefore, utilizing the interference fit principle of the aforementioned blocking plate 101, two symmetrical vertical grooves 104 are also formed on the inner wall of the grinding cylinder 1. Figure 8 , Figure 9 As shown, the inverted V-shaped cleaning scraper 6, which fits with the outer wall of the cone crushing disc 2, is assembled inside the crushing cylinder 1. Specifically, the two ends of the cleaning scraper 6 are respectively interference-fitted into the two vertical grooves 104, and both ends are welded or integrally formed with plug-in blocks. The plug-in blocks are interference-fitted into the vertical grooves 104, so that after the cone crushing disc 2 rotates, the cleaning scraper 6 can directly scrape off the product on the outer wall of the cone crushing disc 2 and discharge it with the washing water. The discharge method is the same as the material discharge method, and both are discharged from the discharge port 102.

[0036] As a further implementation method, such as Figure 10As shown, the outer wall of the conical crushing disc 2 is also welded with several material-pushing protrusions 7 for driving the material to rotate. These protrusions 7 are arranged along the circumference. Specifically, the cross-section of the material-pushing protrusions 7 can be triangular, trapezoidal, or semi-circular. For example, a triangle is chosen with the apex pointing in the direction of rotation. This shape is conducive to cutting and pushing the material. While pushing the material to rotate, the sharp edge can be used to initially tear fibrous materials. Another example is a trapezoid, which has a wider contact area and can stably push the material to rotate. At the same time, the sides of the trapezoid can compress the material. This is suitable for some relatively hard dietary fibers, such as peanut shell fiber. After pretreatment, the trapezoidal protrusions can drive its movement well. A third example is a semi-circular shape, which is gentler when pushing the material, reducing excessive breakage during the movement. This is suitable for pushing some easily broken fruit and vegetable fibers, such as apple fiber and citrus fiber, to ensure that the material is evenly distributed during the rotation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
