Description

Technical Field

[0001] This invention belongs to the technical field of dairy quality inspection equipment, specifically relating to a dairy quality inspection device and method. Background Technology

[0002] Dairy products include products made from fresh cow (sheep) milk and its derivatives as the main raw materials, and can be divided into dairy products, pasteurized milk, and yogurt.

[0003] Quality inspection refers to the activities of checking and verifying whether the quality of products or services meets relevant regulations. It is divided into air quality inspection, engineering quality inspection, product quality inspection, and environmental quality inspection. Quality inspection, sometimes also called testing or experimentation, refers to the technical operation of determining one or more characteristics or performance of a given product, material, equipment, organism, physical phenomenon, process, or service according to prescribed procedures. To ensure the accuracy of test results, it must be conducted within the prescribed testing scope and according to prescribed procedures. Test results should be recorded, usually in the form of a test report or test certificate.

[0004] There are many types of testing equipment. Factories commonly use a variety of testing equipment, including measuring instruments such as calipers, balances, and marking machines. Other common equipment includes quality testing and analysis instruments, material testing equipment, and packaging testing equipment. In the packaging process, common equipment includes packaging material testing instruments, metal testing equipment, non-metal testing equipment, and non-destructive testing equipment.

[0005] In the process of dairy product quality testing, dairy products need to meet the total microbial count requirement. The total microbial count is tested using the GB 4789.2 testing method. In the GB 4789.2 testing method for dairy products, 25g of a single dairy product is weighed and placed in a homogenizing bag containing 225ml of sterile physiological saline. The homogenizing bag is then hammered and shaken by a homogenizer to ensure that the 25g of dairy product and 225ml of sterile physiological saline are thoroughly mixed into a homogenized solution. Then, 1ml of homogenized solution is collected for dilution and testing. Existing homogenizers use a hammering or impact mixing method, which effectively ensures that the 25g sample and 225ml of sterile physiological saline are thoroughly mixed. However, the homogenizing bag needs to be of high strength to avoid breakage. The large-scale use of high-strength, non-degradable homogenizing bags can easily cause environmental pollution. Therefore, we propose a dairy product quality testing device and method. Summary of the Invention

[0006] The purpose of this invention is to provide a dairy product quality testing device and method, which aims to solve the problem of replacing the mixing method of hammering or impact by shaking, avoiding the breakage of homogenization bags, reducing the reliance on high-strength homogenization bags, and using biodegradable homogenization bags to effectively reduce the amount of high-strength homogenization bags used and avoid environmental pollution.

[0018] In a preferred embodiment of the present invention, the clamping assembly includes a V-shaped frame, a push groove, a movable clamping block, guide posts, a fixed clamping block, and reinforcing springs. The V-shaped frame is fixedly connected to the inner walls of the swing frame. The push groove is formed on the inner wall of the V-shaped frame. The fixed clamping block is fixedly connected to the inner wall of the push groove, and the fixed clamping block corresponds to the push groove. The movable clamping block slides between the inner walls of the push groove, and the movable clamping block corresponds to the fixed clamping block. Two guide posts are provided, and the two guide posts are movably inserted between the inner walls of the push groove.

[0019] As a preferred embodiment of the present invention, the guide assembly includes a swing block and an arc groove. Two arc grooves are provided, which are formed between the inner walls of the slide box. Two swing blocks are provided, which slide between the inner walls of the two arc grooves, and both swing blocks are connected to the swing frame.

[0020] As a preferred embodiment of the present invention, an operating terminal is fixedly connected to the inner wall of the fixed frame, and a control panel is fixedly connected to the side of the housing.

[0021] A method for testing dairy product quality using a dairy product quality testing device includes the following steps:

[0022] S1. Fix the homogenizing bag:

[0023] Pull out the handle to remove the slide box from the box. The slide bar guides the movement of the slide box through its sliding engagement with the telescopic groove, ensuring that the slide box slides smoothly in the box. After the slide box slides out of the box, press the two guide posts to compress the two reinforcing springs, causing the fixed clamping block and the movable clamping block to move away from each other. Insert the top of the biodegradable homogenizing bag containing 25g of dairy products and 225ml of sterile saline into the inner wall of the push groove. Release the pressure on the two guide posts. Under the compression of the two reinforcing springs, the movable clamping block and the fixed clamping block fix the homogenizing bag.

[0024] S2, Unlock:

[0025] Once the biodegradable homogenizing bag containing 25g of dairy products and 225ml of sterile saline is fixed, the electric push rod is powered on and started. The output end of the electric push rod extends and retracts, pulling the pawl away from the ratchet, releasing the pawl from the ratchet, allowing the driven gear to rotate normally, and thus unlocking the swing frame.

[0026] S3. Mix evenly:

[0027] After the swing frame is unlocked, the motor torque, speed, and swing time are set via the control panel. Powering on the motor starts it, and the motor's output drives the drive gear to rotate. The motor meshes with the drive gear, which in turn rotates the turntable. The turntable's rotation drives the push-pull rod, which in turn pushes and pulls the eccentric wheel, causing it to swing slightly. This causes the eccentric wheel to deflect the sliding rod, which, through its sliding engagement with the hollow sliding column, causes the hollow sliding column to reciprocate, thus swinging the swing frame. This, in turn, causes the homogenization bag to swing, ensuring that the 25g of dairy product and 225ml of sterile saline solution within the homogenization bag are thoroughly mixed, achieving uniform mixing of the homogenized solution.

[0028] S4, Uniform Stasis:

[0029] After the homogenized liquid is mixed, the operating terminal cuts off the power to the motor and stops the machine according to the set operating parameters. The swing frame swings slowly in the slide box according to inertia until it stops swinging. The electric push rod is energized, and the output end of the electric push rod extends. The output end of the electric push rod pushes the pawl close to the ratchet, so that the pawl and the ratchet are engaged, locking the swing of the swing frame and achieving a uniform stop of the swing frame.

[0030] S5. Disassemble the homogenizing bag:

[0031] After the homogenizing bag stops swinging, pull the handle. With the sliding cooperation of the two limiting grooves and the limiting block, pull the slide box out of the box. By pressing the two guide posts, the fixed clamp and the movable clamp move away from each other, releasing the clamping and fixing of the homogenizing bag. The biodegradable homogenizing bag can then be removed from the swing frame, thus disassembling the homogenizing bag.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. In this solution, after the swing frame is unlocked, the motor torque and speed are set and the swing time is set via the control panel. The motor is then powered on and started. The motor's output drives the drive gear to rotate. The motor meshes with the drive gear, causing it to rotate. The drive gear then rotates the turntable, which in turn drives the push-pull rod to push and pull, causing the push-pull rod to push and pull the eccentric wheel. The eccentric wheel then swings slightly, causing the slide rod to deflect. The slide rod, through its sliding engagement with the hollow slide column, causes the hollow slide column to reciprocate, thus driving the swing frame to swing. This causes the homogenization bag to swing, ensuring that the 25g of dairy product and 225ml of sterile saline solution inside the homogenization bag are thoroughly mixed, achieving uniform mixing of the homogenized liquid. This shaking method replaces the hammering or impact mixing method, preventing the homogenization bag from breaking and eliminating the reliance on high-strength homogenization bags. Furthermore, the use of biodegradable homogenization bags effectively reduces the amount of high-strength homogenization bags used, avoiding environmental pollution.

[0034] 2. In this solution, when clamping and fixing the homogenizing bag, pressing the two guide posts compresses the two reinforcing springs, causing the fixed clamping block and the movable clamping block to move away from each other. The top of the biodegradable homogenizing bag is then inserted between the inner walls of the push groove. The pressure on the two guide posts is released, and under the compression of the two reinforcing springs, the movable clamping block and the fixed clamping block fix the homogenizing bag. Simultaneously, when disassembling the homogenizing bag, pressing the two guide posts causes the fixed clamping block and the movable clamping block to move away from each other, releasing the clamping and fixing of the homogenizing bag. The biodegradable homogenizing bag is then removed from the swing frame, achieving the disassembly of the homogenizing bag. By moving the movable clamping block, the homogenizing bag can be quickly clamped, fixed, and released.

[0035] 3. In this design, during the sliding process of the sliding box, the sliding box drives the hollow sliding column to move. The hollow sliding column and the sliding rod slide together to guide and restrict the movement of the sliding box, ensuring that the sliding box slides in a straight line when the swing frame is locked. At the same time, the two limiting grooves and the two limiting blocks slide together to guide and restrict the sliding of the sliding box, limiting the maximum movement distance of the sliding box and preventing the sliding box from falling off. This also prevents the sliding box and the homogenization bag inside the sliding box from falling off when the device is placed at a high place, thus avoiding the homogenization liquid from breaking and splashing when it falls off the sliding box and the homogenization bag.

[0051] Example 1

[0052] Reference Figure 1 - Figure 12 A dairy product quality testing device, comprising:

[0053] Box 1;

[0054] Sliding box 2 slides between the inner walls of the box 1, and a handle 3 is fixedly connected to the side end of the sliding box 2;

[0055] The partition 32 is fixedly connected between the inner walls of the box 1 and is located on the upper side of the sliding box 2.

[0056] Swing frame 4, the swing frame 4 is disposed between the inner walls of the sliding box 2; and

[0057] The swing mechanism is located between the inner walls of the housing 1 and the slide box 2. The swing mechanism is connected to the swing frame 4 and is used to swing the swing frame 4.

[0058] In this invention, the housing 1 is used to accommodate the partition 32, the sliding box 2, the running terminal 29 and the swing mechanism. The sliding box 2 is used to accommodate the swing frame 4. The partition 32 is used to separate a sealed space from the housing 1 to accommodate the fixing frame 28, the motor 22 and the running terminal 29. The swing frame 4 is used to accommodate the clamping assembly and the homogenizing bag. The swing mechanism is connected to the swing frame 4 to swing the swing frame 4.

[0059] The swing mechanism includes a drive assembly, a linkage assembly, a telescopic assembly, a limiting assembly, a guide assembly, and a clamping assembly. The telescopic assembly is disposed between the inner walls of the slide box 2 and is connected to the swing frame 4. The linkage assembly is disposed at the side end of the housing 1 and is connected to the telescopic assembly. The drive assembly is disposed between the inner walls of the housing 1 and is connected to the linkage assembly. The limiting assembly is disposed between the inner walls of the housing 1 and is connected to the drive assembly. The guide assembly is disposed between the inner walls of the slide box 2 and is connected to the swing frame 4. The clamping assembly is disposed between the inner walls of the swing frame 4.

[0060] In this invention, the telescopic component guides the sliding of the slide box 2 and drives the swing frame 4 to swing. The linkage component drives the swing frame 4 to swing. The drive component provides power for the swing of the swing frame 4. The limiting component locks or unlocks the swing of the swing frame 4. The guide component guides the maximum swing of the swing frame 4. The clamping component clamps and fixes the homogenized liquid.

[0061] The drive assembly includes a gear cover 19, a driven gear 20, a driving gear 21, a motor 22, and a mounting bracket 28. The mounting bracket 28 is fixedly connected to the inner wall of the housing 1. The motor 22 is fixedly connected to the side of the mounting bracket 28, and the output end of the motor 22 extends to the side of the housing 1. The gear cover 19 is fixedly connected to the side of the housing 1 and covers the circumferential surface of the motor 22. The driving gear 21 is disposed between the inner walls of the gear cover 19 and is fixedly connected to the output end of the motor 22. The driven gear 20 is rotatably connected between the inner walls of the gear cover 19. One end of the driven gear 20 extends to the side of the gear cover 19, and the other end of the driven gear 20 extends into the housing 1. The driven gear 20 meshes with the driving gear 21.

[0062] In this invention, the fixing frame 28 is used to support and fix the motor 22 and the running terminal 29. The motor 22 is used to drive the driving gear 21 to rotate. The gear cover 19 is used to seal and protect the driven gear 20 and the driving gear 21. The driving gear 21 drives the driven gear 20 to rotate by meshing with the driven gear 20. The driven gear 20 drives the ratchet 23 and the turntable 18 to rotate. When it is necessary to provide swing power for the swing frame 4, the motor 22 is started. The output end of the motor 22 drives the driving gear 21 to rotate. The driving gear 21 drives the ratchet 23 and the turntable 18 to rotate by meshing with the driven gear 20. The swing frame 4 and the homogenizing bag are swung through the connecting rod assembly and the sliding assembly, so as to provide power for the swing frame 4 and the homogenizing bag to swing.

[0063] The telescopic assembly includes a swing sleeve 11, a hollow slide column 12, a telescopic groove 13, a limiting groove 14, a slide rod 15, and a limiting block 31. The hollow slide column 12 is rotatably connected to the inner wall of the slide box 2, and both ends of the hollow slide column 12 extend to the two side ends of the box body 1. The telescopic groove 13 is opened at the side end of the hollow slide column 12. There are two limiting grooves 14, which are opened on the inner wall of the telescopic groove 13 and are connected to the inner wall of the hollow slide column 12. The slide rod 15 slides between the inner walls of the telescopic groove 13. There are two limiting blocks 31, which slide between the inner walls of the two limiting grooves 14 and are connected to the slide rod 15. The swing sleeve 11 is fixedly connected to the circumferential surface of the hollow slide column 12 and is fixedly connected to the swing frame 4.

[0064] In this invention, the hollow sliding column 12 is used to support and fix the swing sleeve 11, the telescopic groove 13 is opened to accommodate the sliding rod 15, and the two limiting grooves 14 are opened to accommodate the sliding of the two limiting blocks 31. The sliding rod 15 guides and restricts the sliding of the box 1 by sliding with the hollow sliding column 12, and the two limiting blocks 31 guide and restrict the sliding of the sliding box 2 by sliding with the two limiting grooves 14. During the sliding of the sliding box 2, the sliding box 2 drives the hollow sliding column 12 to move. The hollow sliding column 12 and the sliding rod 15 slide together to guide and restrict the movement of the sliding box 2, ensuring that the sliding box 2 slides in a straight line when the swing frame 4 is locked. At the same time, the two limiting grooves 14 and the two limiting blocks 31 slide together to guide and restrict the sliding of the sliding box 2, limiting the maximum sliding distance of the sliding box 2, preventing the sliding box 2 from sliding off, and preventing the sliding box 2 and the homogenizing bag inside the sliding box 2 from falling off when the device is placed at a high place, thus avoiding the homogenizing liquid from falling off and breaking and splashing.

[0065] The linkage assembly includes an eccentric wheel 16, a push-pull rod 17, and a turntable 18. The eccentric wheel 16 is fixedly connected to the side end of the slide rod 15, and the turntable 18 is fixedly connected to the side end of the driven gear 20. The push-pull rod 17 is disposed at the side ends of the turntable 18 and the eccentric wheel 16. One end of the push-pull rod 17 is rotatably connected to the turntable 18, and the other end of the push-pull rod 17 is rotatably connected to the eccentric wheel 16.

[0066] In this invention, the eccentric wheel 16 drives the slide bar 15 to swing slightly. The turntable 18 rotates to drive the push-pull rod 17 to reciprocate. The push-pull rod 17 connects the turntable 18 and the eccentric wheel 16, thereby realizing the transmission of tension between the turntable 18 and the eccentric wheel 16. When the driven gear 20 drives the turntable 18 to rotate, the turntable 18 pushes and pulls the movable clamp 7, causing the movable clamp 7 to reciprocate to push and pull the eccentric wheel 16. The push-pull rod 17 pushes and pulls the eccentric wheel 16 to move. With a slight oscillation, the eccentric wheel 16 drives the slide bar 15 to oscillate slightly, which in turn drives the swing frame 4 to oscillate slightly, achieving uniform shaking of the homogenization bag. This uniformly mixes 25g of dairy products with 225ml of sterile saline. The shaking method replaces the hammering or impact mixing method, avoiding the breakage of the homogenization bag and eliminating the reliance on high-strength homogenization bags. Furthermore, the use of biodegradable homogenization bags effectively reduces the amount of high-strength homogenization bags used, thus avoiding environmental pollution.

[0067] The limiting assembly includes a ratchet 23, a pawl 24, and an electric push rod 25. The ratchet 23 is fixedly connected to the other end of the driven gear 20 and is located between the inner walls of the housing 1. The pawl 24 is rotatably connected to the inner wall of the housing 1. The electric push rod 25 is fixedly connected to the inner wall of the housing 1, and the output end of the electric push rod 25 is rotatably connected to the pawl 24.

[0068] In this invention, ratchet 23 rotates synchronously with driven gear 20. Pad 24 locks the rotation of ratchet 23 by engaging with it, thereby locking the rotation of driven gear 20 and locking the swing of swing frame 4. Electric push rod 25 pushes and pulls pad 24 to rotate. When ratchet 23 needs to engage with pad 24, electric push rod 25 is activated, extending its output end and pushing pad 24 closer to ratchet 23, causing pad 24 to move closer to ratchet 23. Engaging with ratchet 23 stops the swing of the swing frame 4. When it is necessary to release the lock on the swing frame 4, the electric push rod 25 is activated. The output end of the electric push rod 25 retracts and pulls the pawl 24 away from the ratchet 23, releasing the engagement between the pawl 24 and the ratchet 23, allowing the swing frame 4 to swing normally. By pushing and pulling the pawl 24 with the electric push rod 25, the swing of the swing frame 4 can be controlled, thus limiting the swing of the swing frame 4 and facilitating the installation and removal of the homogenizing bag.

[0069] The clamping assembly includes a U-shaped frame 5, a push groove 6, a movable clamping block 7, guide posts 8, a fixed clamping block 9, and reinforcing springs 10. The U-shaped frame 5 is fixedly connected to the inner wall of the swing frame 4. The push groove 6 is opened on the inner wall of the U-shaped frame 5. The fixed clamping block 9 is fixedly connected to the inner wall of the push groove 6 and corresponds to the push groove 6. The movable clamping block 7 slides between the inner walls of the push groove 6 and corresponds to the fixed clamping block 9. Two guide posts 8 are provided, and the two guide posts 8 are movably inserted between the inner walls of the push groove 6. The two cylindrical ends of the two guide posts 8 extend to the two end faces of the U-shaped frame 5, and the two guide posts 8 are connected to the movable clamping block 7. Two reinforcing springs 10 are provided, and the two reinforcing springs 10 are sleeved on the circumferential surface of the two guide posts 8. The two reinforcing springs 10 are located between the inner walls of the two push grooves 6.

[0070] In this invention, the U-shaped frame 5 accommodates the fixed clamping block 9, the movable clamping block 7, and two guide posts 8. The push groove 6 is designed to accommodate the movable clamping block 7. The fixed clamping block 9 and the movable clamping block 7 cooperate with each other. The movable clamping block 7 clamps and fixes the homogenizing bag by moving closer to or further away from the fixed clamping block 9. The two guide posts 8 are movably inserted between the inner walls of the push groove 6 and pass through the two side ends of the U-shaped frame 5. Two reinforcing springs 10 are used to push the movable clamping block 7 out of the push groove 6, so that the movable clamping block 7 moves closer to the fixed clamping block 9 to clamp and fix the homogenizing bag. When clamping and fixing the homogenizing bag, pressing the two guide posts 8 applies pressure to the two clamping blocks. The strong spring 10 compresses and squeezes, causing the fixed clamping block 9 and the movable clamping block 7 to move away from each other. The top of the biodegradable homogenizing bag is inserted between the inner wall of the push groove 6, releasing the pressure on the two guide posts 8. Under the compression of the two reinforcing springs 10, the movable clamping block 7 and the fixed clamping block 9 fix the homogenizing bag. At the same time, when disassembling the homogenizing bag, the two guide posts 8 are pressed, causing the fixed clamping block 9 and the movable clamping block 7 to move away from each other, releasing the clamping and fixing of the homogenizing bag, and removing the biodegradable homogenizing bag from the swing frame 4, thus disassembling the homogenizing bag. By moving the movable clamping block 7, the homogenizing bag can be quickly clamped, fixed, and released.

[0071] The guide assembly includes a swing block 26 and an arc groove 27. There are two arc grooves 27, which are formed between the inner walls of the slide box 2. There are two swing blocks 26, which slide between the inner walls of the two arc grooves 27, and both swing blocks 26 are connected to the swing frame 4.

[0072] In this invention, the two arc-shaped grooves 27 are provided to accommodate the sliding of the two swing blocks 26. The two swing blocks 26, through sliding cooperation with the two arc-shaped grooves 27, guide and restrict the swing of the movable clamping block 7, limiting the maximum swing amplitude of the movable clamping block 7, so that the 25g of dairy products and 225ml of sterile saline in the homogenization bag will oscillate, further enhancing the uniform mixing of the 25g of dairy products and 225ml of sterile saline.

[0073] An operating terminal 29 is fixedly connected to the inner wall of the fixed frame 28, and a control panel 30 is fixedly connected to the side of the housing 1.

[0074] In this invention, the operating terminal 29 is electrically connected to the motor 22, the electric push rod 25 and the control panel 30. The operating terminal 29 is assembled using commercially available electronic components. The operating terminal 29 has a built-in data storage module for storing the operating program. The control panel 30 is installed to facilitate the operator to adjust the operating parameters to meet the needs of homogenizing different dairy products and improve the applicability of the device.

[0075] A method for testing dairy product quality using a dairy product quality testing device includes the following steps:

[0076] S1. Fix the homogenizing bag:

[0077] Pull out the handle 3 to pull the slide box 2 out of the box 1. The slide rod 15 guides the movement of the slide box 2 through the sliding cooperation with the telescopic groove 13, ensuring that the slide box 2 slides smoothly in the box 1. After the slide box 2 slides out of the box 1, press the two guide posts 8 to compress the two reinforcing springs 10, so that the fixed clamp 9 and the movable clamp 7 are separated. Insert the top of the biodegradable homogenizing bag containing 25g of dairy products and 225ml of sterile saline into the inner wall of the push groove 6. Release the pressure on the two guide posts 8. Under the compression of the two reinforcing springs 10, the movable clamp 7 and the fixed clamp 9 fix the homogenizing bag.

[0078] S2, Unlock:

[0079] When the biodegradable homogenizing bag containing 25g of dairy products and 225ml of sterile saline is fixed, the electric push rod 25 is powered on and started. The output end of the electric push rod 25 extends and retracts to pull the pawl 24 away from the ratchet 23, releasing the engagement between the pawl 24 and the ratchet 23, so that the driven gear 20 can rotate normally, thereby unlocking the swing frame 4.

[0080] S3. Mix evenly:

[0081] After the swing frame 4 is unlocked, the torque and speed of the motor 22 and the swing time are set via the control panel 30. The motor 22 is then powered on and started. The output of the motor 22 drives the drive gear 21 to rotate. The motor 22 meshes with the drive gear 21, which in turn drives the turntable 18 to rotate. The turntable 18 rotates, which in turn drives the push-pull rod 17 to push and pull, causing the push-pull rod 17 to push and pull the eccentric wheel 16. The eccentric wheel 16 then swings slightly, causing the slide rod 15 to deflect. The slide rod 15, through its sliding engagement with the hollow slide column 12, drives the hollow slide column 12 to reciprocate, thus driving the swing frame 4 to swing. This causes the swing frame 4 to swing the homogenization bag, thereby ensuring that the 25g of dairy products and 225ml of sterile saline in the homogenization bag are thoroughly mixed, completing the uniform mixing of the homogenized liquid.

[0082] S4, Uniform Stasis:

[0083] After the homogenized liquid is mixed, the operating terminal 29 cuts off the power to the motor 22 according to the set operating parameters. The swing frame 4 swings slowly in the slide box 2 according to inertia until it stops swinging. The electric push rod 25 is energized, and the output end of the electric push rod 25 extends. The output end of the electric push rod 25 pushes the pawl 24 close to the ratchet 23, so that the pawl 24 and the ratchet 23 are engaged, locking the swing of the swing frame 4 and achieving uniform stopping of the swing frame 4.

[0084] S5. Disassemble the homogenizing bag:

[0085] After the homogenizing bag stops swinging, pull the handle 3. With the sliding cooperation of the two limiting grooves 14 and the limiting block 31, pull the slide box 2 out of the box 1. By pressing the two guide posts 8, the fixed clamping block 9 and the movable clamping block 7 are moved away from each other, releasing the clamping and fixing of the homogenizing bag. The biodegradable homogenizing bag can then be taken out of the swing frame 4, thus disassembling the homogenizing bag.

[0086] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
