Description

Technical Field

[0001] This utility model relates to the field of food safety testing technology, and in particular to a food safety testing component extraction device. Background Technology

[0002] In the field of food safety testing, accurate extraction of food components is a crucial step in ensuring the reliability of test results. Many foods are in a solid-liquid mixture, such as some processed foods with broth or fresh ingredients containing moisture. Before conducting component analysis, the solid and liquid components in the food need to be thoroughly mixed to allow for a comprehensive and accurate analysis of the various substances contained within.

[0003] However, existing food safety component extraction devices have many shortcomings when processing solid-liquid mixed foods. Some devices lack effective crushing and mixing functions, resulting in uneven solid-liquid mixing. This makes the test results unable to accurately reflect the overall composition of the food, affecting the accuracy of the test.

[0004] Furthermore, existing devices also present inconveniences in terms of inspection and maintenance. Due to their complex internal structure and lack of convenient maintenance design, when the device malfunctions or requires regular maintenance, it often necessitates significant time and manpower for disassembly and installation. This not only increases operating costs but may also lead to further damage and shorten the device's lifespan due to untimely maintenance. Therefore, developing a food safety component extraction device that can efficiently crush and mix materials, facilitate solid-liquid separation and discharge, and is easy to inspect and maintain is of significant practical importance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing devices, such as the lack of effective crushing and mixing functions, which leads to uneven solid-liquid mixing and results in inaccurate food composition, affecting the accuracy of testing. Furthermore, existing devices are inconvenient to maintain and repair. Therefore, this invention proposes a food safety component extraction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A food safety testing component extraction device includes a frame, on which a crushing box is fixedly installed;

[0008] The feed box is fixedly installed on the top of the crushing box and communicates with its interior;

[0009] A discharge channel is located at one end of the crushing box;

[0010] The pulverizing assembly, located inside the pulverizing chamber, includes a servo motor, a drive gear driven by the servo motor, a driven gear meshing with the drive gear, a rotating shaft driven by the driven gear, and multiple pulverizing blades fixedly sleeved on the rotating shaft.

[0011] The discharge assembly includes a sealing plate slidably disposed at the bottom of the discharge channel, strip grooves and sealing grooves opened on both sides of the sealing plate, limiting blocks slidably disposed on both sides of the discharge channel, and an L-shaped discharge plate fixedly embedded in the inner wall of the discharge channel, wherein the L-shaped discharge plate is provided with multiple filter holes.

[0012] The protective assembly includes an arc-shaped cover hinged to the top of the crushing chamber, a handle on the arc-shaped cover, a hook mounted on the handle, and a latch fixed to the side wall of the feed chamber, wherein the latch and the hook are engaged to close the access hole.

[0013] In one possible design, the inspection hole in the protective assembly is located on the side wall of the crushing chamber, and the arc-shaped cover rotates about a hinge axis near the top of the discharge channel to open and close the inspection hole.

[0014] In one possible design, the crushing assembly further includes a first protective box and a second protective box fixed to the side wall of the crushing chamber. The servo motor is fixed inside the second protective box, and its output shaft passes through the first protective box and is connected to the drive gear. One end of the rotating shaft extends into the first protective box and is fixed to the driven gear.

[0015] In one possible design, the crushing assembly further includes a first protective box and a second protective box fixed to the side wall of the crushing chamber. The servo motor is fixed inside the second protective box, and its output shaft passes through the first protective box and is connected to the drive gear. One end of the rotating shaft extends into the first protective box and is fixed to the driven gear.

[0016] In one possible design, the discharge assembly further includes a second fixing block fixed to the inner wall of the crushing chamber and a fixing inclined block symmetrically disposed at its end, wherein the fixing inclined block cooperates with the sealing inclined groove to seal the discharge channel;

[0017] When the limit block disengages from the strip groove, the sealing plate falls, causing the liquid to flow through the filter holes into the L-shaped discharge plate for discharge.

[0018] In one possible design, the discharge assembly further includes a first fixing block fixed to the inner wall of the top of the crushing chamber, the first fixing block being located above the sealing plate to limit its upward movement.

[0019] In one possible design, the location of the inspection hole corresponds to the axial distribution area of ​​the crushing blade.

[0020] In one possible design, the filter holes are evenly distributed along the bottom surface of the groove of the L-shaped discharge plate.

[0021] In this application, during use, a mixture of solid and liquid food is fed into the device through a feeding box. At this time, the servo motor is activated, and the output shaft of the servo motor drives the drive gear to rotate. The drive gear drives the driven gear to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives multiple pulverizing blades to rotate, pulverizing the food inside and ensuring the solid-liquid mixture is thoroughly pulverized, facilitating subsequent testing.

[0022] After mixing is complete, the limiting block can be moved laterally by pulling the plate. The limiting block moves slightly and aligns with the strip groove. At this point, the sealing plate moves downward under gravity, and the limiting block gets stuck inside the strip groove. The sealing sloping groove and the fixed sloping block no longer correspond. The liquid in the mixture is then filtered through the filter holes on both sides and discharged along the groove of the L-shaped discharge plate for collection. After discharge, the limiting block is completely pulled out, the sealing plate is discharged, and the solid mixture is discharged through the discharge channel, facilitating subsequent testing.

[0023] When the internal parts of the device need maintenance, the latches and hooks can be opened, and the arc-shaped cover can be opened using the handle. The arc-shaped cover can then be rotated around the pivot on the side near the top of the discharge channel, exposing the inspection hole and facilitating maintenance of the internal parts. This makes the device easy to use.

[0024] Beneficial effects: By using a servo motor to drive the drive gear, driven gear, rotating shaft, and multiple pulverizing blades, the solid-liquid mixed food inside the device can be fully pulverized and mixed, making the solid-liquid mixture reach a uniform state. This provides a good foundation for subsequent food safety testing component extraction and helps improve the accuracy and reliability of the test results.

[0025] A unique discharge assembly was designed, which controls the lateral movement of the limiting block by pulling a plate, thereby enabling the sealing plate to move downwards and be fixed in place. After mixing, the liquid is first filtered through the filter holes and discharged and collected along the L-shaped discharge plate. Then, the limiting block is completely pulled out, allowing the solid mixture to be discharged through the discharge channel. This step-by-step discharge method is simple to operate, facilitates the separate processing and collection of solid and liquid components, and meets the needs of extracting different components in food safety testing.

[0026] The device is equipped with an access port and protective components. When internal maintenance is required, simply open the latches and hooks, and rotate the curved cover around the pivot using the handle to expose the access port, facilitating maintenance of the internal components. This design significantly reduces maintenance difficulty and time, improves the device's efficiency and lifespan, and lowers operating costs.

[0027] The entire device is rationally laid out, with the crushing, discharging, and protective components working together to achieve multiple functions within a limited space. The connections and transmission relationships between the components are clear, ensuring stable and reliable operation, which not only guarantees the performance of the device but also facilitates manufacturing and installation.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] In one embodiment: Refer to Figure 1-5 The specific implementation of an extraction device is as follows:

[0036] The device mainly consists of a frame 1, a crushing box 3, a feeding box 5, a discharge channel 18, an inspection hole 17, protective components, a crushing component, and a discharge component. The frame 1 serves as the supporting structure for the entire device, providing a stable mounting base for other components. The crushing box 3 is fixedly installed inside the frame 1, with its top connected to the feeding box 5 for feeding solid-liquid mixed food materials; a discharge channel 18 is provided at one end for discharging the processed material; and an inspection hole 17 is provided on one side for convenient inspection and maintenance of the device's interior.

[0037] The protective assembly for protecting the inspection hole 17 consists of an arc-shaped cover 8, a handle 4, a hook 7, and a latch 6. The arc-shaped cover 8 is hinged to one side of the top of the crushing chamber 3 and can rotate around the hinge point. The handle 4 is located on the top side of the arc-shaped cover 8 for easy gripping by the operator. The hook 7 is fixedly installed on the top of the handle 4, and the latch 6 is fixedly installed on one side of the feed box 5. The latch 6 and the hook 7 are engaged, and the arc-shaped cover 8 can be closed and opened to protect the inspection hole 17 by engaging and disengaging them. When the device is operating normally, the latch 6 and the hook 7 are engaged, so that the arc-shaped cover 8 tightly covers the inspection hole 17, preventing external impurities from entering the device. When the device needs maintenance, the latch 6 and the hook 7 are opened, and the arc-shaped cover 8 is rotated around the pivot 25 near the top of the discharge channel 18 using the handle 4 to open it, exposing the inspection hole 17. The operator can then perform maintenance on the inside of the device through the inspection hole 17.

[0038] The pulverizing assembly is located inside the pulverizing chamber 3 and is used to pulverize materials. It includes a rotating shaft 25, pulverizing blades 14, a first protective box 2, a second protective box 21, a servo motor 22, a drive gear 23, and a driven gear 24. The rotating shaft 25 rotates through one side of the pulverizing chamber 3, and multiple pulverizing blades 14 are fixedly fitted onto its outer wall. The pulverizing blades 14 are evenly distributed on the rotating shaft 25 and are used to pulverize the added solid-liquid mixture. The first protective box 2 is fixedly installed on one side of the pulverizing chamber 3, and the second protective box 21 is fixedly installed on one side of the first protective box 2, providing protection for the internal components. The servo motor 22 is fixedly installed inside the second protective box 21, and its output shaft rotates through the interior of the first protective box 2 and is fixedly mounted on the drive gear 23. One end of the rotating shaft 25 extends into the interior of the first protective box 2 and is fixedly fitted with the driven gear 24. The drive gear 23 and the driven gear 24 mesh with each other. When the device is running, the servo motor 22 is started. The output shaft of the servo motor 22 drives the drive gear 23 to rotate, the drive gear 23 drives the driven gear 24 to rotate, and the driven gear 24 drives the rotating shaft 25 to rotate. This causes the multiple pulverizing blades 14 on the rotating shaft 25 to rotate, which fully pulverizes the solid-liquid mixture of food put into the pulverizing box 3, so that the solid-liquid mixture reaches a uniform state, providing a good foundation for the subsequent testing process and improving the accuracy and reliability of the test results.

[0039] After the solid-liquid mixture is crushed and mixed in the crushing chamber 3, the discharge operation is performed. The limiting block 11 is moved laterally by pulling plate 9, causing it to move slightly. At this point, the limiting block 11 aligns with the strip groove 19, and the sealing plate 12 moves downwards under gravity. The limiting block 11 is then locked inside the strip groove 19. The sealing inclined groove 20 no longer corresponds to the fixed inclined block 16, and the discharge channel 18 connects to the inside of the crushing chamber 3. The liquid in the mixture is filtered through the filter holes 26 on both sides and discharged along the groove of the L-shaped discharge plate 10. The operator can place a collection container at the outlet of the L-shaped discharge plate 10 to collect the liquid. After the liquid is discharged, the limiting block 11 is completely pulled out. At this point, the sealing plate 12 loses its limiting position and continues to move downwards under gravity. The solid mixture is discharged through the discharge channel 18. The operator can also place a collection container at the outlet of the discharge channel 18 to collect the solid. This step-by-step discharge method is simple to operate, facilitates the separate processing and collection of solid and liquid components, meets the needs of different component extraction in food safety testing, avoids the workload of discharging the mixture together and then performing complex separation operations, reduces component loss and the possibility of cross-contamination, and further improves the accuracy of test results.

[0040] This application can be used in the field of food safety testing, or in other fields applicable to this application.

[0041] In another embodiment: Reference Figure 1-5A food safety testing component extraction device is disclosed, which is used in the field of food safety testing. The discharge assembly is located inside the discharge channel 18 to control material discharge. It includes an L-shaped discharge plate 10, a limiting block 11, a pulling plate 9, a sealing plate 12, a strip groove 19, a sealing inclined groove 20, a second fixing block 15, a fixing inclined block 16, and a first fixing block 13. The L-shaped discharge plate 10 is fixedly embedded in the inner wall of one side of the discharge channel 18, with multiple filter holes 26 at one end for filtering liquids in the mixture. The limiting block 11 slides through both sides of the discharge channel 18, with the pulling plate 9 fixedly installed at one end. Pulling the pulling plate 9 allows the limiting block 11 to move laterally. The sealing plate 12 is slidably connected to the bottom inner wall of the discharge channel 18, with strip grooves 19 on both sides. The strip grooves 19 cooperate with the limiting block 11; when the limiting block 11 is engaged in the strip groove 19, it limits the sealing plate 12. Sealing grooves 20 are also provided on both sides of the sealing plate 12. The second fixing block 15 is fixedly installed on one side of the inner wall of the crushing box 3, and two symmetrically arranged fixing blocks 16 are fixedly connected to one end of the second fixing block 15. The fixing blocks 16 cooperate with the sealing grooves 20. When the sealing plate 12 is in the initial position, the fixing blocks 16 are engaged in the sealing grooves 20 to seal the discharge channel 18 and prevent material leakage. The first fixing block 13 is fixedly installed on the top inner wall of the crushing box 3, located above the sealing plate 12 and cooperating with the sealing plate 12 to limit the upward movement of the sealing plate 12.

[0042] However, as is well known to those skilled in the art, the working principle and wiring method of the servo motor 22 are conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
