Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a high-precision testing device for solid food additives. Background Technology

[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as items that are traditionally both food and Chinese medicine, but does not include items intended for treatment. Food can be classified into liquid food and solid food according to its form. During the production process of solid food, it is necessary to sample and inspect it. During the quality inspection, it is necessary to test the content of food additives in solid food, so it is necessary to use food additive testing equipment for solid food.

[0003] However, existing testing devices have many shortcomings. During the production, transportation, and storage of solid food additives, uneven component distribution can easily occur due to factors such as differences in particle density and vibration stratification (e.g., separation of fine powder and coarse particles, uneven mixing of additives and carriers). A sample from a single sampling point (with different particle sizes of solids) cannot reflect the true component content of the overall sample, resulting in significant deviations between the test results and the actual situation. Utility Model Content

[0004] To overcome the technical defects of existing technologies, this utility model provides a high-precision detection device for solid food additives. A servo motor drives a stirring rod and a reverse spiral dispersing blade to bidirectionally stir and disperse the material in the U-shaped inner chamber, thoroughly breaking up clumps and eliminating stratification. Combined with multi-specification perforated plates for grading and screening, it avoids the limitations of single sampling, ensuring the sample reflects the overall true situation and significantly reducing detection deviation. The inner chamber is equipped with multi-aperture perforated plates, and the servo motor's reverse rotation, along with connecting wedges and wedge grooves for positioning, allows for quick perforation without disassembly. The bottom baffle automatically resets and precisely receives the material in the receiving box, enabling continuous operation.

[0005] The technical solution adopted by this utility model is: a high-precision detection device for solid food additives, including an outer chamber;

[0006] The bottom of the outer chamber is provided with a discharge chute for solid food additives. A strainer plate is fixedly installed in the discharge chute. The surface of the strainer plate is provided with multiple strainer grooves. An inner chamber is provided inside the outer chamber. The inner chamber is U-shaped. The surface of the inner chamber is fixed with multiple strainer plates at equal intervals in a ring to control the discharge of different solid food additive particle sizes. The diameter of the through holes opened on the surface of the multiple strainer plates is different.

[0007] A servo motor is installed on one side of the outer chamber. The output end of the servo motor extends into the outer chamber and is connected to one end of the stirring rod set in the outer chamber. A connecting plate is installed on the other end of the stirring rod. A second spring is installed in a blind groove opened on the surface of the connecting plate. The other end of the second spring abuts against one end of a connecting wedge block that is slidably connected in the blind groove opened on the surface of the connecting plate. Multiple connecting wedge grooves that are adapted to the connecting wedge block are evenly distributed in a ring on one side of the inner chamber.

[0008] Preferably, the size of the baffle plate is adapted to the size of the discharge trough, and the baffle plate covers the surface of the discharge trough when the solid food additive particles are discharged.

[0009] Preferably, the bottom surface of the discharge plate is provided with a bottom baffle for controlling the discharge of solid food additive particles. An L-shaped slider is fixedly installed on the surface of the bottom baffle. A groove adapted to the L-shaped slider is opened on the surface of the discharge plate. The bottom baffle is slidably connected to the bottom surface of the discharge plate through the L-shaped slider and the groove.

[0010] Preferably, a fixed slider is fixedly installed on the surface of the bottom baffle, and a T-shaped fixing rod is slidably connected to the surface of the fixed slider. The T-shaped fixing rod is fixedly installed on one side of the material leakage plate, and a spring for resetting is sleeved on the outer surface of the T-shaped fixing rod.

[0011] Preferably, a receiving box for receiving solid food additive granules is provided directly below the outer compartment, and the receiving box is located directly below the discharge chute.

[0012] Preferably, the surface of the stirring rod is equipped with multiple spiral dispersing blades, and the spiral directions of two adjacent spiral dispersing blades are opposite.

[0013] Preferably, a wedge-shaped control plate is fixedly installed at one end of the bottom baffle, and a control rod is rotatably connected to the surface of the outer compartment. One end of the control rod extends into the outer compartment and connects to the inner compartment.

[0014] The beneficial effects of this utility model are:

[0015] The servo motor drives the stirring rod and the reverse spiral dispersing blades to stir and disperse the material in the U-shaped inner chamber in both directions. This can completely break up agglomerates and eliminate stratification caused by density differences, ensuring that the material evenly covers the sluice plate. At the same time, the multi-specification sluice plates enable graded screening, avoiding the limitations of single sampling, so that the test sample can reflect the true particle size and composition of the overall material, and greatly reduce the detection deviation.

[0016] The device has multiple sets of perforated plates with different apertures arranged in a ring inside the chamber. With the help of the servo motor reversing and the connecting wedge block and wedge groove positioning structure, the perforated plates can be quickly switched without disassembling the parts, meeting the detection requirements of additives with different particle sizes. In addition, the automatic reset design of the bottom baffle and the precise receiving box enable continuous operation of stirring-screening-collection.

[0017] The bottom baffle switch can be easily controlled by the wedge-shaped control plate, and the inner chamber position can be easily adjusted by the control lever. No professional personnel are required to operate it. At the same time, the U-shaped inner chamber reduces material residue, and the T-shaped fixing rod and spring ensure stable operation of the baffle. It is suitable for testing various solid food additives (such as powder and granules). Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figure 1-9As shown, this embodiment provides a high-precision detection device for solid food additives, including an outer chamber 1;

[0030] The bottom of the outer chamber 1 is provided with a discharge trough 3 for solid food additives. A strainer plate 4 is fixedly installed in the discharge trough 3. Multiple strainer grooves 5 are provided on the surface of the strainer plate 4. An inner chamber 12 is provided inside the outer chamber 1. The inner chamber 12 is U-shaped. Multiple strainer plates 13 for controlling the discharge of different solid food additive particle sizes are fixed in a ring at equal intervals on the surface of the inner chamber 12. The diameter of the through holes opened on the surface of the multiple strainer plates 13 is different.

[0031] A servo motor 11 is installed on one side of the outer chamber 1. The output end of the servo motor 11 extends into the outer chamber 1 and is connected to one end of the stirring rod 19 located in the outer chamber 1. A connecting plate 21 is installed on the other end of the stirring rod 19. A spring 22 is installed in a blind groove on the surface of the connecting plate 21. The other end of the spring 22 abuts against one end of a connecting wedge 23 that is slidably connected in the blind groove on the surface of the connecting plate 21. A plurality of connecting wedge grooves 24 that are adapted to the connecting wedge 23 are evenly distributed in a ring on one side of the inner chamber 12.

[0032] The U-shaped inner chamber 12 can accommodate the material to be tested and can reduce the residue of material on the chamber wall, ensuring that the material fully participates in the screening during testing. Multiple annularly fixed baffles 13 on its surface, with different through hole diameters, can achieve graded screening of solid food additives with different particle sizes, meeting the needs of multi-specification testing without replacing the entire set of screening components, thus improving the flexibility of testing. The servo motor 11 provides precise power to the device. When rotating forward, it drives the stirring rod 19 to rotate, realizing the stirring and dispersing of materials. When rotating in reverse, it assists in switching the baffles 13. The connecting plate 21, spring 22, connecting wedge 23 and connecting wedge groove 24 cooperate. The elasticity of spring 22 makes the connecting wedge 23 and connecting wedge groove 24 tightly engaged, which can quickly and accurately position the inner chamber 12, ensuring that the corresponding baffle 13 is precisely connected with the discharge trough 3, ensuring screening accuracy and avoiding detection errors caused by positioning deviation.

[0033] Furthermore, the size of the sluice plate 13 is adapted to the size of the discharge trough 3, and when the solid food additive particles are discharged, the sluice plate 13 covers the surface of the discharge trough 3.

[0034] The size of the stencil 13 is adapted to the discharge trough 3, and the stencil 13 covers the surface of the discharge trough 3 when the solid food additive particles are discharged. This ensures that the material passes completely through the through holes of the stencil 13 during the screening process, preventing the material from leaking out from the gap between the stencil 13 and the discharge trough 3. This prevents unfiltered material from mixing into the screened material, ensuring the accuracy of the test results, and avoiding material waste.

[0035] Furthermore, the bottom surface of the discharge plate 4 is provided with a bottom baffle 25 for controlling the discharge of solid food additive particles. An L-shaped slider 6 is fixedly installed on the surface of the bottom baffle 25. The surface of the discharge plate 4 is provided with a groove 7 that matches the L-shaped slider 6. The bottom baffle 25 is slidably connected to the bottom surface of the discharge plate 4 through the L-shaped slider 6 and the groove 7.

[0036] The bottom baffle 25 controls the opening and closing of the trough 5. During the preparation stage of the test, the trough 5 is closed to prevent premature leakage of materials and ensure that the materials are evenly mixed before screening. During the test, the trough 5 is opened to ensure that qualified materials are discharged smoothly. The sliding cooperation between the L-shaped slider 6 and the trough 7 provides a stable guide for the movement of the bottom baffle 25, preventing the bottom baffle 25 from deviating during the sliding process, ensuring that it can accurately block or open the trough 5, and improving the stability of operation.

[0037] Furthermore, a fixed slider 10 is fixedly installed on the surface of the bottom baffle 25, and a T-shaped fixing rod 8 is slidably connected to the surface of the fixed slider 10. The T-shaped fixing rod 8 is fixedly installed on one side of the material leakage plate 4, and a spring 9 for resetting is sleeved on the outer surface of the T-shaped fixing rod 8.

[0038] The fixed slider 10 cooperates with the T-shaped fixed rod 8 to further restrict the movement trajectory of the bottom baffle 25, so that it can only slide along the direction of the T-shaped fixed rod 8, thereby enhancing the stability of the movement of the bottom baffle 25. The spring 9 sleeved on the T-shaped fixed rod 8 has a reset function. When there is no need to discharge material, the elastic force of the spring 9 can drive the bottom baffle 25 to automatically reset and close the trough 5. There is no need for manual reset, which simplifies the operation process. At the same time, it ensures that the bottom baffle 25 and the material discharge plate 4 are tightly fitted in the closed state to prevent material leakage.

[0039] Furthermore, a receiving box 26 for receiving solid food additive granules is provided directly below the outer compartment 1, and the receiving box 26 is located directly below the discharge chute 3.

[0040] The receiving box 26 is located directly below the discharge trough 3, which can accurately receive qualified materials discharged from the discharge trough 3, preventing materials from falling outside the device and causing pollution or waste. It facilitates the subsequent collection, weighing or further testing of the screened materials, improving the practicality and ease of operation of the device.

[0041] Furthermore, the surface of the stirring rod 19 is equipped with multiple spiral dispersing blades 20, with the spiral directions of two adjacent spiral dispersing blades 20 being opposite.

[0042] Multiple spiral dispersing blades 20 on the surface of the stirring rod 19 rotate under the drive of the servo motor 11, which can fully stir the material. The spiral directions of adjacent blades are opposite, which can generate bidirectional force. On the one hand, the material is evenly dispersed to prevent the material from agglomerating into large particles and avoiding clogging of the through holes of the stencil plate 13 or affecting the screening accuracy. On the other hand, the material is dispersed in all directions to ensure that the material evenly covers the surface of the stencil plate 13, so that the material in each area can participate in the screening, thereby improving the screening efficiency and detection accuracy.

[0043] Furthermore, a wedge-shaped control plate 18 is fixedly installed at one end of the bottom baffle 25, and a control rod 16 is rotatably connected to the surface of the outer compartment 1. One end of the control rod 16 extends into the outer compartment 1 and is connected to the inner compartment 12.

[0044] The wedge-shaped control plate 18 at one end of the bottom baffle 25 increases the contact area for hand operation, making it easier for operators to slide the bottom baffle 25 by pushing the wedge-shaped control plate 18 to open or close the trough 5, thus improving the ease of operation. The control rod 16 on the surface of the outer chamber 1 is connected to the inner chamber 12. Operators can easily drive the inner chamber 12 to rotate by rotating the control rod 16, and switch the trough 13 in conjunction with the reverse rotation of the servo motor 11, without having to go deep into the device for adjustment, thus reducing the difficulty of operation.

[0045] The working principle of this utility model is as follows: Before testing, according to the target particle size of the solid food additive to be tested, the position of the inner chamber 12 is initially adjusted by the control rod 16 on the surface of the outer chamber 1. The servo motor 11 is started to reverse, and its output end drives the stirring rod 19 to rotate in the opposite direction. The connecting plate 21 at the other end of the stirring rod 19 rotates together. At this time, the connecting wedge block 23 in the blind groove of the connecting plate 21, under the pre-tightening force of the spring 22, forms a matching engagement with the connecting wedge groove 24 evenly distributed in a ring on one side of the inner chamber 12. The wedge surface structure achieves precise positioning of the inner chamber 12. After positioning, among the multiple equidistant baffles 13 fixed in a ring on the surface of the inner chamber 12, the baffle 13 corresponding to the target particle size just covers the surface of the discharge trough 3 at the bottom of the outer chamber 1. The size of the baffle 13 is completely matched with the discharge trough 3, ensuring that the screening channel is sealed and leak-free, laying the foundation for accurate grading.

[0046] At the same time, the bottom baffle 25 on the bottom surface of the material leakage plate 4 is in an initial closed state. The bottom baffle 25 slides with the groove 7 on the surface of the material leakage plate 4 through the L-shaped slider 6. The fixed slider 10 on its surface maintains the initial position along the T-shaped fixed rod 8. The spring 9 sleeved on the T-shaped fixed rod 8 has no compression deformation. The bottom baffle 25 completely covers the multiple grooves 5 on the surface of the material leakage plate 4 to prevent the material from leaking prematurely. The receiving box 26 directly below the outer chamber 1 is aligned with the discharge chute 3 to prepare for receiving the material.

[0047] The solid food additive to be tested is put into the U-shaped inner chamber 12 inside the outer chamber 1. The servo motor 11 is started to rotate forward, and its output end drives the stirring rod 19 to rotate forward. The multiple spiral dispersing blades 20 installed on the surface of the stirring rod 19 rotate accordingly. Since the spiral directions of two adjacent spiral dispersing blades 20 are opposite, the material is subjected to bidirectional spiral force during rotation. On the one hand, it is evenly dispersed to avoid large particles from agglomerating and affecting the screening accuracy. On the other hand, it is dispersed to the surrounding area to ensure that the material is evenly covered on the surface of the positioned stencil plate 13.

[0048] Solid food additive particles that meet the diameter of the through holes of the stencil 13 pass through the through holes of the stencil 13 and the trough 5 of the stencil 4 in sequence under the combined action of gravity and stirring force. At this time, the wedge-shaped control plate 18 at one end of the bottom baffle 25 is pushed, causing the bottom baffle 25 to slide along the slide 7. The fixed slider 10 compresses the spring 9, the trough 5 opens, and qualified particles fall directly into the receiving box 26 below for collection. Particles with a diameter larger than the through holes of the stencil 13 are intercepted in the inner chamber 12, realizing the preliminary classification of materials with different particle sizes. During the screening process, the structural design of the U-shaped inner chamber 12 can prevent materials from remaining on the chamber wall and ensure thorough screening.

[0049] When it is necessary to test solid food additives with different particle sizes, the servo motor 11 is restarted in reverse, the stirring rod 19 drives the connecting plate 21 to rotate in the opposite direction, and the connecting wedge block 23 is subjected to the reverse squeezing force of the connecting wedge groove 24 of the inner chamber 12, which overcomes the elastic force of the spring 22 and retracts into the blind groove of the connecting plate 21, disengaging from the engaging state with the connecting wedge groove 24. At this time, the inner chamber 12 can be easily driven to rotate by the control rod 16, switching to the stencil 13 with a surface through hole diameter that meets the new testing requirements, and positioning is achieved again by the engaging of the connecting wedge block 23 with the corresponding connecting wedge groove 24.

[0050] After switching, release the wedge-shaped control plate 18. Under the reset force of the spring 9, the bottom baffle 25 slides back to its original position along the T-shaped fixing rod 8 via the fixed slider 10, resealing the trough 5. The material to be tested can then be added again, repeating the stirring and screening process of the servo motor 11 rotating forward, achieving continuous high-precision testing of multiple particle sizes. During the testing process, large-diameter materials intercepted can be cleaned uniformly by disassembling the inner chamber 12, making operation convenient.
