Description

Technical Field

[0001] This utility model relates to the field of pulverizing equipment technology, specifically to a shiitake mushroom ultrafine powder processing device with graded pulverizing function. Background Technology

[0002] Shiitake mushrooms, as an edible fungus, are rich in polysaccharides, amino acids, vitamins, and other active ingredients, and have broad application prospects in the food, health product, and pharmaceutical fields. With the increasing market demand for deep-processed shiitake mushroom products, processing them into ultrafine powder has become an important way to expand their application scope. Ultrafine powder not only improves the absorption rate and bioavailability of shiitake mushrooms but also facilitates the formulation and processing of subsequent products.

[0003] Patent CN215611904U discloses a food grinding and processing device, including a base. Four sets of support rods are welded to the top of the base and arranged in a rectangular array. Mounting components are welded to the top of the support rods, and a primary grinding mechanism is welded to the corresponding side wall of the mounting components. The primary grinding mechanism includes a guide plate, a feed hopper, grinding rollers, and a first grinding chamber. This device, through the combined use of the primary and secondary grinding mechanisms, can limit the particle size of the food to be ground, avoiding the need for repeated grinding operations required by traditional grinders that cannot achieve the desired particle size in a single grinding process. Furthermore, the coordinated use of the grinding balls with the second and third grinding chambers allows for more precise grinding of the food, ensuring continued operation of subsequent production and greatly improving the device's practicality.

[0004] The aforementioned device only performs a simple two-stage process of "primary crushing + secondary grinding" in the food crushing process, without clear particle size gradient control. This results in a large fluctuation range in particle size after primary crushing, and the secondary grinding cannot be specifically adapted to different initial particle sizes. Consequently, the particle size difference in the same batch of products can be several times or even tens of times, which fails to meet the core requirement of "particle size uniformity" in food processing. Utility Model Content

[0005] The purpose of this invention is to provide a mushroom ultrafine powder processing device with graded crushing function, in order to solve the technical problem that the simple two-stage processing of "one crushing + two grinding" without clear particle size gradient control results in a large fluctuation range of particle size after the first crushing and the second grinding cannot be specifically adapted to different initial particle sizes, thus causing large differences in particle size in the same batch of products.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A shiitake mushroom ultrafine powder processing device with graded crushing function includes a crushing cylinder. A connecting plate is fixedly installed on the lower surface of the crushing cylinder. A multi-stage crushing mechanism for shiitake mushroom raw materials is fixedly installed on the upper surface of the connecting plate. A cone top is fixedly installed on the upper surface of the multi-stage crushing mechanism for shiitake mushroom raw materials. A guide rod is fixedly installed on the outer surface of the cone top. The guide rod is slidably installed in a guide groove, which is opened on the inner ring wall of the crushing cylinder.

[0008] As a preferred embodiment of this utility model, a conical ring is fixedly installed inside the connecting plate. The inner ring wall of the conical ring is provided with two conical surfaces, which are simultaneously fitted onto the outer surface of the multi-stage crushing mechanism for shiitake mushroom raw materials.

[0009] As a preferred embodiment of this utility model, the multi-stage crushing mechanism for shiitake mushroom raw materials includes a connecting column fixedly installed on the lower surface of the cone top. The outer surface of the connecting column is also provided with two sets of cone surfaces, and the upper and lower surfaces of the two cone surfaces on the outer surface of the connecting column are respectively fixedly installed with a first crushing tooth, a second crushing tooth, and a third crushing tooth.

[0010] As a further embodiment of this utility model, the first crushing tooth, the second crushing tooth, and the third crushing tooth are respectively opposite to the first crushing surface, the second crushing surface, and the third crushing surface, and the first crushing surface, the second crushing surface, and the third crushing surface are respectively disposed on the upper and lower surfaces of the two conical surfaces disposed on the conical ring.

[0011] As a further embodiment of this utility model, the first to third crushing teeth and the first to third crushing surfaces have crushing gaps, and the gaps are 8-12mm, 3-5mm and 0.8-1.5mm respectively, so that they gradually decrease from top to bottom.

[0012] As a further preferred embodiment of this utility model, a first grinding disc is fixedly installed on the lower surface of the connecting column. The lower surface of the first grinding disc is fixedly connected to the output shaft of the motor, while the motor is fixedly installed on the upper surface of the connecting plate. The upper surface of the first grinding disc is perpendicular to the second grinding disc, and the second grinding disc is fixedly installed on the lower surface of the conical ring. The grinding distance between the first grinding disc and the second grinding disc is 0.1 to 0.3 mm.

[0013] Compared with the prior art, the beneficial effects of the mushroom ultrafine powder processing device with graded pulverization function of this utility model are as follows:

[0014] Through the coordinated structure of the crushing cylinder, cone top, cone ring, and multi-stage crushing mechanism for shiitake mushroom raw materials, efficient graded processing of shiitake mushrooms from diced to ultrafine powder is achieved. The motor drives the connecting column and the crushing teeth and grinding discs of each stage to rotate synchronously. With the crushing spacing gradually reduced (8-12mm → 3-5mm → 0.8-1.5mm) and the grinding spacing of 0.1-0.3mm, a step-like refining logic is formed. It achieves coarse crushing through shearing and tearing, and ultrafine refining through extrusion and grinding, which effectively ensures the uniformity of product particle size and avoids the problem of large particle fluctuations in traditional devices. At the same time, the guide rod and guide groove ensure stable operation. The rotation of the first grinding disc to discharge material enables continuous operation. While improving crushing accuracy, it also improves processing efficiency and reduces the risk of equipment operation affecting product quality. Attached Figure Description

[0024] like Figures 1-2 As shown, the shiitake mushroom ultrafine powder processing device with graded crushing function in this embodiment of the utility model includes a crushing cylinder 1. A connecting plate 109 is fixedly installed on the lower surface of the crushing cylinder 1. A multi-stage crushing mechanism 2 for shiitake mushroom raw materials is fixedly installed on the upper surface of the connecting plate 109. A cone apex 102 is fixedly installed on the upper surface of the multi-stage crushing mechanism 2 for shiitake mushroom raw materials. A guide rod 103 is fixedly installed on the outer surface of the cone apex 102. The guide rod 103 is slidably installed in the guide groove 101, which is opened on the inner ring wall of the crushing cylinder 1.

[0025] A conical ring 104 is fixedly installed inside the connecting plate 109. Two conical surfaces are provided on the inner ring wall of the conical ring 104 and are simultaneously fitted onto the outer surface of the multi-stage crushing mechanism 2 for mushroom raw materials.

[0026] like Figure 3 , 4 As shown, the multi-stage crushing mechanism 2 for shiitake mushroom raw materials includes a connecting column 202 fixedly installed on the lower surface of the cone top 102. The outer surface of the connecting column 202 is also provided with two sets of cone surfaces, and the upper and lower surfaces of the two cone surfaces on the outer surface of the connecting column 202 are respectively fixedly installed with a first crushing tooth 203, a second crushing tooth 204 and a third crushing tooth 205.

[0027] The first crushing tooth 203, the second crushing tooth 204 and the third crushing tooth 205 are respectively opposite to the first crushing surface 105, the second crushing surface 106 and the third crushing surface 107, and the first crushing surface 105, the second crushing surface 106 and the third crushing surface 107 are respectively disposed on the upper and lower surfaces of the two conical surfaces disposed on the conical ring 104.

[0028] The first to third pulverizing teeth 205 and the first to third pulverizing surfaces 107 have pulverizing gaps, which are 8-12 mm, 3-5 mm and 0.8-1.5 mm respectively, so that they gradually decrease from top to bottom.

[0029] After being cut into pieces, the shiitake mushroom material enters from the top of the crushing cylinder 1 and slides down the inclined surface of the cone apex 102 under the action of gravity. The guiding effect of the cone apex 102 causes the material to initially converge and move towards the gap between the multi-stage crushing mechanism 2 and the conical ring 104. At this time, the activated multi-stage crushing mechanism 2 slides stably in the guide groove 101 through the guide rod 103, ensuring the rotational stability of the multi-stage crushing mechanism 2. The poured-in shiitake mushrooms first enter the first crushing surface 105 between the multi-stage crushing mechanism 2 and the conical ring 104. The gap between the multi-stage crushing mechanism 2 and the first crushing surface allows the material to be initially crushed by the rotation of the multi-stage crushing mechanism 2, breaking larger mushroom particles to a certain size. The initially crushed material then falls into the gap between the multi-stage crushing mechanism 2 and the second crushing surface 106. Because this gap is smaller than the first crushing gap, the multi-stage crushing mechanism 2 and the second crushing surface 106 can further refine the material, reducing the particle size. Subsequently, the material enters the gap between the multi-stage crushing mechanism 2 and the third crushing surface 106. The gap between 07 and 08 is the smallest in the three-stage crushing process. Under the action of the multi-stage crushing mechanism 2 and the third crushing surface 107, the material is crushed to a finer particle size, preparing it for subsequent grinding processes. After three-stage crushing, the material falls between the multi-stage crushing mechanism 2 and the second grinding disc 108, and as the multi-stage crushing mechanism 2 rotates, it cooperates with the fixed second grinding disc 108 to perform final ultra-fine grinding, making the material meet the particle size requirements of ultra-fine powder, thus completing the grading and crushing process of shiitake mushrooms. Furthermore, through a progressive processing flow of "three-stage crushing + final grinding," with the gaps between each stage gradually reduced, the mushroom material can be gradually refined from a diced state. The first crushing stage processes larger particles, followed by the second and third crushing stages to continuously reduce particle size, and finally, the grinding disc completes the ultrafine grinding, resulting in a final product with uniform particle size that precisely meets the requirements for ultrafine powder. This effectively avoids the problem of uneven particle size caused by the simple processing stages of traditional crushing devices, thus ensuring the consistency of crushing and grinding effects and reducing the risk of product quality being affected by unstable equipment operation.

[0030] A first grinding disc 206 is fixedly installed on the lower surface of the connecting column 202. The lower surface of the first grinding disc 206 is fixedly connected to the output shaft of the motor 201, while the motor 201 is fixedly installed on the upper surface of the connecting plate 109. The upper surface of the first grinding disc 206 is perpendicular to the second grinding disc 108. The second grinding disc 108 is fixedly installed on the lower surface of the conical ring 104. The grinding distance between the first grinding disc 206 and the second grinding disc 108 is 0.1 to 0.3 mm.

[0031] After the motor 201 starts, its output shaft drives the connecting column 202 and the first crushing tooth 203, second crushing tooth 204, third crushing tooth 205 and first grinding disc 206 fixed on the connecting column 202 to rotate synchronously. This allows the chopped shiitake mushroom material to enter the crushing cylinder 1 and slide down along the cone apex 102 to a crushing gap of 8-12 mm between the first crushing tooth 203 and the first crushing surface 105. At this point, the rotating first crushing tooth 203 interacts with the fixed first crushing surface 105, breaking large pieces of shiitake mushroom into particles with a size suitable for this gap through shearing and tearing, completing the initial crushing. The material after initial crushing continues to fall under gravity, entering a gap of 3-5 mm between the second crushing tooth 204 and the second crushing surface 106. Due to the reduced gap, the rotating second crushing tooth 204 and the second crushing surface 106 perform finer crushing of the material, further refining the particles and reducing their size. Subsequently, the material falls into the gap between the third crushing tooth 205 and the first grinding disc 206. Within a 0.8–1.5 mm gap between the three grinding surfaces 107, the high-speed rotating third grinding tooth 205 cooperates with the third grinding surface 107 to deeply grind the material, refining the particles to near-ultra-fine powder, preparing it for subsequent grinding. The material after three-stage grinding finally falls into the 0.1–0.3 mm grinding gap between the first grinding disc 206 and the second grinding disc 108, allowing the rotating first grinding disc 206 and the fixed second grinding disc 108 to generate strong squeezing and grinding action, further refining the material to ultra-fine powder, ultimately obtaining shiitake mushroom ultra-fine powder that meets the requirements, completing the entire graded grinding process, forming a step-by-step refinement logic of "coarse crushing-medium crushing-fine crushing-fine grinding", avoiding the problem of excessive particle size fluctuation, significantly improving the particle size uniformity of the same batch of products, and the rotation of the first grinding disc 206 will also throw the ground shiitake mushroom out, allowing it to fall from the bottom of the grinding cylinder 1 and be collected.

[0032] When the above technical solution is used, after the material enters from the top of the crushing cylinder 1, it slides down the inclined surface of the cone apex 102 under the action of gravity. The guiding effect of the cone apex 102 causes the material to initially converge and move towards the gap between the connecting column 202 and the conical ring 104. At this time, as the motor 201 drives the connecting column 202 to operate, it also allows the guide rod 103 to slide stably in the guide groove 101, ensuring the rotational stability of the connecting column 202. The material first enters the gap between the first crushing tooth 203 and the first crushing surface 105 on the conical ring 104. Under the rotation of the multi-stage crushing mechanism 2 for mushroom raw materials, the first crushing tooth 203 and the first crushing surface 105 cooperate to initially crush the material, breaking the larger mushroom particles to a certain particle size. The material that has undergone initial crushing continues to fall and enters the gap between the second crushing tooth 204 and the first crushing surface 105. The gap between the second grinding surfaces 106 is smaller than the first grinding gap, allowing the second grinding teeth 204 and the second grinding surfaces 106 to further refine and grind the material, reducing the particle size. Subsequently, the material enters the gap between the third grinding teeth 205 and the third grinding surfaces 107, which is the smallest gap in the three-stage grinding process. Under the action of the third grinding teeth 205 and the third grinding surfaces 107, the material is ground to a finer particle size, preparing it for subsequent grinding processes. The material after three-stage grinding falls between the first grinding disc 206 and the second grinding disc 108. The first grinding disc 206 rotates synchronously with the connecting column 202, cooperating with the fixed second grinding disc 108 to perform final ultra-fine grinding of the material, making it meet the particle size requirements of ultra-fine powder, thus completing the grading and grinding process of shiitake mushrooms.

[0033] By employing a step-by-step refinement logic of "coarse crushing - medium crushing - fine crushing - fine grinding," the problem of excessive fluctuations in particle size is avoided, significantly improving the particle size uniformity of the same batch of products. This effectively avoids the problem of uneven particle size caused by the simple processing steps of traditional crushing devices, thereby ensuring the consistency of crushing and grinding effects and reducing the risk of product quality being affected by unstable equipment operation.

[0034] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention.
