Description

Technical Field

[0001] This utility model relates to the field of flaxseed technology, and in particular to a flaxseed pulverizer. Background Technology

[0002] Flaxseed, as a crop seed with both nutritional and economic value, is rich in Omega-3 fatty acids, dietary fiber, and various active ingredients. It is widely used in food processing, health product research and development, and feed production. However, flaxseed has a hard and flat oval shell, making it difficult for humans and processing equipment to fully extract its effective components in its natural state. Therefore, it is necessary to crush the shell to break down the shell structure and release the internal nutrients. This makes flaxseed crushing equipment a key processing equipment in related industries.

[0003] In existing technology, such as Chinese Patent No. CN 207153793 U, a grinding mill includes a base, a left and right side plate fixed above the base, a front and rear end plate, a forward and backward tilting plate, and a motor fixed to the base. The space enclosed by the left and right side plates and the forward and backward tilting plates constitutes a receiving area, and the space enclosed by the left and right side plates and the front and rear end plates constitutes a grinding area. A feeding hopper is provided above the receiving area, and a discharging hopper is provided below the grinding area. The grinding area is characterized by having a first grinding roller and a second grinding roller; the motor drives the first grinding roller, and the second grinding roller is driven in the opposite direction to the first grinding roller; the surfaces of the first and second grinding rollers are always in contact; and the first grinding roller has a rough surface structure. This utility model uses a specially designed, rough-surfaced grinding roller to grind flaxseed into powder. This type of grinding mill has the advantages of both not producing oil and grinding flaxseed into a fine powder.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantage is that the equipment only completes the crushing and discharging process. However, the core value of flaxseed lies in its active ingredients such as Omega-3 fatty acids (alpha-linolenic acid) and vitamin E. These ingredients are highly sensitive to temperature (they usually begin to oxidize and decompose above 35°C). During the crushing process, the friction of the rollers generates heat, which can raise the temperature of the flaxseed powder to 40-50°C. If it is not cooled in time, the residual heat will continue to damage the nutrients. Furthermore, flaxseed contains about 30%-40% oil. After crushing, the cell walls rupture, and a large amount of oil seeps out. If it is not treated in time, the powder will clump together due to the oil. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, the equipment only completes the crushing and discharging of flaxseed, but the core value of flaxseed lies in active ingredients such as Omega-3 fatty acids and vitamin E. These ingredients are highly sensitive to temperature. During the crushing process, the friction of the rollers generates heat, which will make the flaxseed powder high in temperature. If it is not cooled in time, the residual heat will continue to damage the nutrients.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flaxseed pulverizer, comprising a pulverizing chamber and a discharge hopper, the flaxseed pulverizer further comprising: A vertical, sealed chamber is connected to the bottom of the discharge hopper; Two silent axial flow fans are respectively installed on both sides of the vertical sealed chamber; Two inclined baffles are respectively installed at the top of the vertical sealed cavity; Among them, the two inclined guide vanes are located on top of the two silent axial flow fans. The inclined guide vanes are inclined downward at a 30° angle to the horizontal direction, so that the cooling airflow flows obliquely downward along the side wall of the chamber to form a wall-adhering airflow layer. A screening component is located at the bottom of the silent axial flow fan; Two reflux collection devices are located on one side of the vertical sealed chamber.

[0007] In a preferred embodiment, the screening component includes: Mounting frame one is snapped into the interior of the vertical sealed chamber; A primary screen is installed inside the mounting frame one; Mounting frame two is snapped into the interior of the vertical sealed chamber; The second mounting frame is located at the bottom of the first mounting frame; A secondary screen is installed inside the second mounting frame; The aperture of the secondary screen is smaller than that of the primary screen. The secondary screen and the primary screen are inclined at a 15° angle to the horizontal direction. When the airflow passes through from both sides, it needs to pass through the gap between the secondary screen and the primary screen. The heat is carried away by the airflow, while the mesh structure of the screen physically intercepts the material.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: the 15° inclined screen, combined with the grading logic of the upper coarse screen and the lower fine screen, allows the flaxseed powder to slide naturally along the screen surface, which not only prolongs the contact time between the material and the screen and improves the screening accuracy, but also avoids the material from accumulating and clogging on the screen surface. At the same time, when the airflow passes through the gaps in the screen, it can cool the material in the screening process a second time, further enhancing the cooling effect and improving the processing efficiency.

[0009] In a preferred embodiment, the collection and return component includes: Two coarse material return ports are opened on the side of the inclined guide plate near the second mounting frame and the first mounting frame; Among them, the two coarse material return ports are flush with the second mounting frame and the first mounting frame; Two collection boxes are snapped onto one side of the two coarse material return ports; Two collection chambers are located inside the two collection boxes.

[0010] The technical effects of adopting the above-mentioned further solution are as follows: the design of the coarse material return port being flush with the screen ensures that the coarse particles intercepted by the primary and secondary screens can smoothly slide into the return port along the inclined screen surface, avoiding the accumulation of coarse material at the end of the screen. The combination of the snap-fit ​​collection box and the independent collection chamber can not only quickly receive coarse material, but also achieve physical isolation between coarse material and finished product, preventing cross-contamination.

[0011] In a preferred embodiment, the collection and return component further includes: Two material pumps are installed on one side of each of the two collection boxes; Two suction pipes are respectively connected to one end of the two suction pumps; Among them, the two suction pipes penetrate through the middle of the collection box, and the two suction pipes are flush with the bottom wall of the collection chamber; Two feed pipes are respectively connected to the other end of the two feed pumps; The top ends of the two conveying pipes penetrate the feed hopper, and the two conveying pipes are connected to the interior of the feed hopper.

[0012] The technical advantage of adopting the above-mentioned further solution is that the design of the suction pipe being flush with the bottom wall of the collection chamber can completely extract the coarse material in the collection chamber and avoid residual accumulation.

[0013] In a preferred embodiment, the flaxseed grinder further includes: Four handles are installed in two groups on both sides of the two collection boxes; The two handles are located on either side of the pump.

[0014] The technical advantage of adopting the above-mentioned further solution is that, through the symmetrical force design, operators can easily hold and pull out the snap-fit ​​collection box, and can complete the disassembly and installation of the collection box without the aid of tools.

[0015] In a preferred embodiment, the flaxseed grinder further includes: Two silicone sealing rings are respectively installed at the bottom of the discharge hopper and the top of the vertical sealed chamber; The two silicone sealing rings are tightly connected.

[0016] The technical effect of adopting the above-mentioned further solution is that by elastically squeezing and filling the gaps in the seams to construct a sealed channel, on the one hand, it can prevent outside air from entering the chamber and causing flaxseed powder to oxidize, and on the other hand, it can prevent the powder from scattering from the seams during the falling process.

[0017] In a preferred embodiment, the flaxseed grinder further includes: The base is installed on the outside of the crushing chamber.

[0018] The technical effect of adopting the above-mentioned further solution is to provide stable support for heavy components such as the crushing box, vertical sealed chamber, and collection box.

[0019] In a preferred embodiment, the flaxseed grinder further includes: An anti-stick coating is sprayed onto the inner wall of the vertical sealed cavity. The discharge port is located at the bottom of the vertical sealed chamber.

[0020] The technical effect of adopting the above-mentioned further solution is that the anti-stick coating sprayed on the inner wall of the vertical sealed cavity reduces the adhesion of oily flaxseed powder (especially the powder formed by oil condensation during cooling) to the cavity wall by utilizing the low surface energy characteristics.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a silent axial flow fan and an inclined guide plate to alter the airflow trajectory, creating a wall-mounted airflow layer. This airflow design leverages the constraint of the chamber sidewalls to ensure the airflow makes all-around enveloping contact with the material without interfering with the vertical descent trajectory of the flaxseed powder. Through heat exchange, residual heat generated during the pulverization process is quickly removed, avoiding the problems of material scattering or damage to heat-sensitive components caused by direct airflow in traditional cooling methods. This rapidly lowers the temperature of the flaxseed powder to the safe threshold for heat-sensitive components, increasing the nutrient retention rate by 30%-40%. Simultaneously, the cooling process, combined with the anti-stick coating, effectively solves the clumping problem caused by the oil content of the flaxseed powder, significantly improving product uniformity and flowability, meeting the requirements for raw material fineness in high-end fields such as food and health products.

[0022] This invention, by setting up a collection and return component, allows the flaxseed powder output from the crushing box to enter a two-stage inclined screen for particle size classification. The classified coarse material is then reintroduced into the crushing process through the return structure, ultimately forming a closed-loop operation of crushing-cooling-screening-returning, which improves material quality, increases raw material utilization, and creates complementary functions.

[0025] 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. Example 1

[0026] Please see Figures 1-4 This embodiment provides a flaxseed grinder, the specific concept of which is as follows: A flaxseed pulverizer includes a pulverizing chamber 1 and a discharge hopper 4. The flaxseed pulverizer also includes a vertical sealed chamber 5, two silent axial flow fans 10, two inclined guide plates 11, and a screening component.

[0027] The vertical sealed chamber 5 is connected to the bottom of the discharge hopper 4.

[0028] Among them, two silent axial flow fans 10, which play a role in cooling, are installed on both sides of the vertical sealed chamber 5.

[0029] Among them, two inclined guide plates 11, which play the role of airflow buffer, are respectively installed on the top of the vertical sealed chamber 5.

[0030] It should be noted that the two inclined guide vanes 11 are located on top of the two silent axial flow fans 10. The inclined guide vanes 11 are inclined downward at a 30° angle to the horizontal direction, so that the cooling airflow flows obliquely downward along the side wall of the chamber, forming a wall-adhering airflow layer.

[0031] The screening component is located at the bottom of the silent axial flow fan 10.

[0032] As examples, in this embodiment, the screening components include: mounting frame 15, primary screen 16, mounting frame 2 13, and secondary screen 14.

[0033] The mounting frame 15 is snapped into the interior of the vertical sealed chamber 5.

[0034] The primary screen 16, which performs the screening function, is located inside the mounting frame 15.

[0035] The mounting frame 2 13 is snapped into the interior of the vertical sealed chamber 5.

[0036] In addition, mounting frame 2 13 is located at the bottom of mounting frame 1 15.

[0037] The secondary screen 14, which performs the screening function, is located inside the second mounting frame 13.

[0038] It should be noted that the aperture of the secondary screen 14 is smaller than that of the primary screen 16. The secondary screen 14 and the primary screen 16 are inclined at a 15° angle to the horizontal direction. When the airflow passes through from both sides, it needs to pass through the gap between the secondary screen 14 and the primary screen 16. The heat is carried away by the airflow, while the mesh structure of the screen will physically intercept the material.

[0039] In this embodiment, the vertical sealed chamber 5 serves as the core processing space. The cooling airflow generated by the silent axial flow fans 10 on both sides of the chamber is guided by the inclined guide plate 11 at the top of the chamber, changing the airflow trajectory and abandoning the traditional direct airflow. Instead, it becomes a wall-mounted airflow layer flowing along the side wall of the chamber, preventing the airflow from blowing away the material. The screening component utilizes the synergistic effect of gravity and the inclined angle of the screen surface to make the falling flaxseed powder slide slowly along the screen surface, achieving dynamic screening. Coarse particles cannot pass through the screen gaps and naturally slide towards the return channel along the inclined screen surface, while fine particles pass through two stages of screens to complete the grading. At the same time, when the airflow passes through the screen gaps, it can cool the material in the screening process a second time, further enhancing the cooling effect. Example 2

[0040] Please see Figures 1-4 Based on Example 1, this example provides a flaxseed grinder, the specific concept of which is as follows: The flaxseed grinder also includes: four handles 7, two silicone sealing rings 12, a base 20, an anti-stick coating 19, a feed inlet, and two collection return parts.

[0041] The four handles 7 are installed in two groups on both sides of the two collection boxes 6, and the two handles 7 are located on both sides of the material pump 8.

[0042] The two silicone sealing rings 12, which serve a sealing function, are respectively installed at the bottom of the discharge hopper 4 and the top of the vertical sealed chamber 5, and the two silicone sealing rings 12 are tightly connected.

[0043] The base 20 is installed on the outside of the crushing box 1.

[0044] Among them, the anti-stick coating 19, which plays an anti-sticking role, is sprayed on the inner wall of the vertical sealed chamber 5.

[0045] The discharge port is located at the bottom of the vertical sealed chamber 5.

[0046] The two collection and return components are located on one side of the vertical sealed chamber 5.

[0047] As examples, in this embodiment, the collection and return components include: two coarse material return ports 18, two collection boxes 6, two collection chambers 17, two material pumps 8, two suction pipes 9, and two conveying pipes 3.

[0048] The two coarse material return ports 18 are located on the side of the inclined guide plate 11 near the second mounting frame 13 and the first mounting frame 15.

[0049] In addition, the two coarse material return ports 18 are flush with the mounting frame 2 13 and mounting frame 1 15.

[0050] The two collection boxes 6 are attached to one side of the two coarse material return ports 18.

[0051] The two collection chambers 17 are located inside the two collection boxes 6.

[0052] Among them, the two material pumps 8 that play a recycling role are respectively installed on one side of the two collection boxes 6.

[0053] The two suction pipes 9 are respectively connected to one end of the two pumps 8.

[0054] In addition, two suction pipes 9 penetrate the middle of the collection box 6, and the two suction pipes 9 are flush with the bottom wall of the collection chamber 17.

[0055] The two conveying pipes 3 are respectively connected to the other end of the two pumps 8.

[0056] In addition, the top ends of the two conveying pipes 3 penetrate the feed hopper 2, and the two conveying pipes 3 are connected to the interior of the feed hopper 2.

[0057] In this embodiment, when the coarse material in the collection chamber 17 accumulates to a certain amount, the pump 8 is started, and the coarse material is sucked in through the suction pipe 9 flush with the bottom wall of the collection chamber 17. It is then transported to the feed hopper 2 through the conveying pipe 3, mixed with the newly added flaxseed raw material, and then re-enters the crushing box 1, forming a closed loop for coarse material processing. The bottom of the discharge hopper 4 is tightly fitted with two silicone sealing rings 12 installed on the top of the vertical sealed chamber 5. The gap between the joints is filled by elastic compression to build a sealed channel, blocking the outside air from entering the chamber and causing the flaxseed powder to oxidize. At the same time, it prevents the powder from drifting away from the joints during the falling process. The anti-stick coating 19 sprayed on the inner wall of the vertical sealed chamber 5 uses the low surface energy characteristics to reduce the adhesion of oily flaxseed powder (especially the powder that condenses oil during the cooling process) to the chamber wall. Combined with the slight blowing of the wall-mounted airflow on the chamber wall, a dual anti-sticking effect of physical anti-sticking and airflow-assisted desorption is formed to ensure that there is no material accumulation on the inner wall of the chamber.

[0058] Working principle: Flaxseed first enters the grinding chamber 1 through the feed hopper 2. After being ground by the internal structure of the grinding chamber 1, the resulting flaxseed powder is discharged from the discharge hopper 4. A silicone sealing ring 12, tightly connected between the discharge hopper 4 and the top of the vertical sealed chamber 5, ensures airtightness, allowing the powder to smoothly enter the vertical sealed chamber 5. At this time, the silent axial flow fans 10 on both sides of the vertical sealed chamber 5 are activated. The cooling airflow generated by the fans (with a wind speed controlled at 0.8-1.2 m / s to avoid blowing away the light powder) is transported upwards to the top of the chamber, where it encounters the inclined guide plate 11 installed directly above the silent axial flow fans 10. The baffle plate guides the originally vertical upward airflow into a wall-mounted airflow layer along the side wall of the chamber. The airflow flows closely to the inner wall of the chamber, forming a ring-shaped cooling zone. When the falling flaxseed powder passes through this zone, the airflow comes into full contact with the powder surface, quickly carrying away the heat generated during the rolling process. This causes the powder temperature to drop to 25-30℃ within 10-15 seconds (meeting the preservation requirements of heat-sensitive components such as Omega-3 fatty acids). At the same time, the non-stick coating 19 on the inner wall of the chamber effectively prevents oily powder from adhering to the wall surface due to the condensation of grease during the cooling process, ensuring the cleanliness of the chamber interior and reducing the frequency of subsequent cleaning.

[0059] After cooling, the flaxseed powder continues to fall to the screening component at the bottom of the silent axial flow fan 10. It first passes through the primary screen 16. Due to the inclined design of the screen surface, the powder slowly slides along the screen surface under the action of gravity. During this process, the powder with smaller particle size meets the preliminary screening requirements and falls through the gaps in the screen to the lower secondary screen 14. However, the larger coarse particles, such as incompletely broken flaxseed shells and small clumps of particles, are intercepted by the screen and continue to slide along the inclined screen surface to one side of the chamber. Finally, they slide into the coarse material return port 18, which is located on the inclined guide plate 11 near the mounting frame 15. Because the height of the return port is flush with the end of the screen, it ensures that the coarse particles enter smoothly without accumulation. The coarse particles entering the coarse material return port 18 fall directly into the collection chamber 1 of the corresponding collection box 6. Inside the 7, the collection chamber 17 is a sealed structure to prevent coarse particles from oxidizing and deteriorating due to prolonged contact with air. When the coarse material in the collection chamber 17 accumulates to a certain amount, it can be judged by observing the transparent window on the side of the collection box 6. The operator does not need to stop the machine and can directly start the suction pump 8 on one side of the collection box 6. The suction pump 8 sucks in the coarse particles through the suction pipe 9, and then delivers them to the inside of the feed hopper 2 through the conveying pipe 3 at a stable pressure. They are mixed with the newly added flaxseed raw materials and re-enter the crushing box 1 for secondary crushing, so as to make full use of the raw materials and improve the raw material utilization rate. Finally, the flaxseed powder that meets the particle size requirements is discharged from the discharge port at the bottom of the vertical sealed chamber 5, completing the processing process. The handles 7 on both sides of the collection box 6 make it easy to manually disassemble and clean the collection chamber 17.
