Description

Technical Field

[0001] This utility model belongs to the field of food sample thawing technology, and in particular relates to a sample thawing device for food testing. Background Technology

[0002] Food testing is an important means of ensuring food safety. Through testing, harmful substances in food, such as pesticide residues, veterinary drug residues, heavy metals, and pathogens, can be detected in a timely manner, preventing these substances from entering the human body and causing various diseases. Strict food testing can supervise food producers and operators to comply with laws and regulations, ensure that food on the market meets safety standards, prevent unqualified food from entering the market, and maintain a fair and competitive market environment.

[0003] For example, Chinese patent CN216816242U discloses a sample thawing device for food testing, including a thawing chamber. A motor is installed on the outside of the thawing chamber, and a rotating shaft is connected to the output end of the motor. A placement plate is connected to the surface of the rotating shaft, and through holes are opened on the surface of the placement plate. A main pipe is installed at the upper end of the thawing chamber, and branch pipes are connected to the surface of the main pipe. In this utility model, by setting the main pipe and branch pipes at the upper end of the thawing chamber, and cooperating with the conveying pipe and nozzle, water spray can be used to spray the food to be thawed, thereby thawing the food. In addition, with the guide slope, guide groove and recycling box, the thawing water can be recycled, which is conducive to recycling and can save resources. By setting the motor on the outside of the thawing chamber, and cooperating with the rotating shaft, the placement plate can be driven to rotate, which is conducive to turning the food on the placement plate, which not only makes the food thawing more even, but also improves the thawing efficiency.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has several drawbacks in its use. For example, when thawing food samples, it uses a thawing water spray, but the sprayed water cannot completely cover the food sample, thus reducing the thawing rate. Furthermore, after thawing, the food sample is clamped and secured with a cover plate, requiring personnel to remove the cover plate before removing the food, which is inconvenient and makes it difficult to remove the thawed food. Therefore, we propose a food sample thawing device for testing. Utility Model Content

[0006] The purpose of this invention is to provide a sample thawing device for food testing, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a sample thawing device for food testing, comprising:

[0008] A thawing box has a thawing groove inside. The inner wall of the thawing groove has symmetrically opened limit grooves. A sliding plate is slidably installed between two limit grooves. The sliding plate has several drainage holes. A rotating rod is rotatably installed on the top of the sliding plate and inside the thawing groove. Several stirring rods are fixedly installed on the periphery of the rotating rod and inside the thawing groove.

[0009] A support rod is fixedly installed on one side of the defrosting box. A sliding groove is provided on one side of the support rod and at the top of the defrosting box. A movable plate is slidably installed in the sliding groove. A motor is fixedly installed on the top of the movable plate. The output end of the motor passes through the movable plate and is coaxially connected to the rotating rod.

[0010] A drive assembly, located within a support rod, is used to drive the movable plate to move up and down;

[0011] A circular groove is formed inside the defrosting chamber and located below the defrosting tray. A heating wire is fixedly installed inside the circular groove, and a thermometer is fixedly installed on the other side of the defrosting chamber.

[0012] In this technical solution, a thermometer is used to energize the heating wire, which heats the thawing water in the thawing tank. During the heating process, personnel can observe the thermometer to judge the temperature of the thawing water in the thawing tank. The temperature of the thawing water can be precisely controlled according to the sample that needs to be thawed, so that the sample thawing speed can reach the fastest speed without damaging the sample, thus ensuring that the sample thawing efficiency can be accelerated.

[0013] When the motor is started, its output shaft drives a rotating rod to rotate, causing the rod to rotate on a sliding plate. Simultaneously, the rotating rod also drives several stirring rods to rotate, agitating the sample in the thawing tank and ensuring it makes full contact with the thawing water, thus accelerating thawing. After thawing, the motor can be turned off. Then, a drive assembly moves a moving plate upwards, which in turn moves the motor upwards, which in turn moves the rotating rod upwards, causing the sliding plate to move upwards between two limit slots. This upward movement of the sliding plate also moves the sample upwards, while several drainage holes drain water from the sample on the sliding plate until all the sample is above the thawing water. At this point, the thawed sample can be removed without needing to put hands into the thawing water, ensuring easy removal without injury.

[0014] In the above technical solution, the driving component further includes:

[0015] A threaded rod is rotatably mounted in a sliding groove, and the bottom end of the threaded rod penetrates a movable plate;

[0016] A rotating groove is formed inside the support rod and located below the slide groove. A worm gear is rotatably installed inside the rotating groove. The top end of the worm gear extends through the top of the rotating groove into the slide groove and is coaxially connected to the threaded rod. A worm is meshed and installed on one side of the worm gear and inside the rotating groove. One end of the worm extends through one side of the rotating groove to the outside and is fixedly installed with a handle.

[0017] In this technical solution, rotating the handle causes the worm gear to rotate. Under meshing action, the worm gear rotates the worm wheel, which in turn rotates the threaded rod. The threaded rod's rotation causes the moving plate to move upwards, which in turn moves the motor upwards. The motor's upward movement causes the rotating rod to move upwards, which in turn moves the sliding plate upwards. This causes the sliding plate to move upwards between the two limiting grooves. Simultaneously, the upward movement of the sliding plate moves the sample upwards, and several drainage holes allow water to drain from the sample on the sliding plate until all the sample on the sliding plate is above the thawing water. At this point, personnel can remove the thawed sample. This ensures that personnel can easily remove the thawed sample without putting their hands into the thawing water, preventing injury to their hands.

[0018] In the above technical solution, the threaded rod is threadedly connected to the movable plate, the top end of the worm gear is rotatably connected to the slide groove, and the worm is rotatably connected to the rotating groove.

[0019] In this technical solution, it is ensured that the rotation of the threaded rod can drive the moving plate to move up and down, that the top of the worm wheel can rotate normally in the slide groove, and that the worm can rotate normally in the rotating groove.

[0020] In the above technical solution, the output shaft of the motor is rotatably connected to the moving plate, and the sliding plate is slidably connected to the defrosting tank.

[0021] In this technical solution, it is ensured that the output shaft of the motor can rotate normally within the moving plate, and that the sliding plate can slide normally within the thawing tank.

[0022] In the above technical solution, furthermore, the plurality of stirring rods are distributed in a ring at equal intervals, and the cross-section of the rotating rod has a T-shaped structure.

[0023] In this technical solution, it is ensured that several stirring rods can stir the sample more evenly, and that the rotating rod will not fall off the sliding plate.

[0024] In the above technical solution, the cross-section of the chute is T-shaped, and the drainage holes are distributed in an annular pattern at equal intervals.

[0025] In this technical solution, it is ensured that the movable plate will not fall out of the chute, and that several drainage holes can completely drain the thawing water from the sliding plate.

[0026] The beneficial effects of this utility model are:

[0027] 1. This food testing sample thawing device uses a thermometer to energize a heating wire, which heats the thawing water in the thawing tank. During the heating process, personnel can observe the thermometer to determine the temperature of the thawing water. The temperature of the thawing water can be precisely controlled according to the sample to be thawed, thereby thawing the sample as quickly as possible without damaging it, ensuring efficient thawing.

[0028] 2. This food testing sample thawing device, equipped with a motor, operates by rotating a rotating rod via its output shaft. This rotating rod then rotates on a sliding plate, simultaneously driving several stirring rods to agitate the sample within the thawing tank. This ensures the sample makes full contact with the thawing water, accelerating the thawing process. After thawing, the motor is turned off. A drive assembly then moves a moving plate upwards, which in turn moves the motor upwards, which in turn moves the rotating rod upwards. This upward movement of the rotating rod in turn moves the sliding plate upwards, causing it to move between two limiting slots. Simultaneously, the upward movement of the sliding plate moves the sample upwards, and several drainage holes drain water from the sample on the sliding plate until all the sample is above the thawing water. At this point, the thawed sample can be removed without requiring the user to put their hands into the thawing water, ensuring easy and safe removal without injury. Attached Figure Description

[0042] Example 1:

[0043] Please see Figure 1 - Figure 6 As shown, this embodiment provides a sample thawing device for food testing, including:

[0044] A thawing box 1 has a thawing groove 2 inside. The inner wall of the thawing groove 2 has symmetrically opened limit grooves 3. A sliding plate 4 is slidably installed between the two limit grooves 3. Several drainage holes 5 are opened on the sliding plate 4. A rotating rod 6 is rotatably installed on the top of the sliding plate 4 and inside the thawing groove 2. Several stirring rods 7 are fixedly installed on the periphery of the rotating rod 6 and inside the thawing groove 2.

[0045] A support rod 8 is fixedly installed on one side of the defrosting box 1. A sliding groove 9 is provided on one side of the support rod 8 and at the top of the defrosting box 1. A movable plate 10 is slidably installed in the sliding groove 9. A motor 11 is fixedly installed on the top of the movable plate 10. The output end of the motor 11 passes through the movable plate 10 and is coaxially connected to the rotating rod 6.

[0046] The drive assembly is located inside the support rod 8 and is used to drive the moving plate 10 to move up and down.

[0047] A circular groove 17 is formed inside the defrosting chamber 1 and located below the defrosting tank 2. A heating wire 18 is fixedly installed inside the circular groove 17, and a thermometer 19 is fixedly installed on the other side of the defrosting chamber 1.

[0048] The heating wire 18 is energized by the thermometer 19. The heating wire 18 heats up and heats the thawing water in the thawing tank 2. During the heating process, the personnel can observe the thermometer 19 to judge the temperature of the thawing water in the thawing tank 2. The temperature of the thawing water can be precisely controlled according to the sample that needs to be thawed, so that the sample thawing speed can reach the fastest speed without damaging the sample, thus ensuring that the sample thawing efficiency can be accelerated.

[0049] When the motor 11 is started, its output shaft drives the rotating rod 6 to rotate on the sliding plate 4. Simultaneously, the rotation of the rotating rod 6 also drives several stirring rods 7 to rotate, stirring the sample in the thawing tank 2 and ensuring sufficient contact between the sample and the thawing water, thus accelerating the thawing process. After thawing is complete, the motor 11 can be turned off. Then, the drive assembly moves the moving plate 10 upwards, which in turn moves the motor 11 upwards. The upward movement will cause the rotating rod 6 to move upward, which in turn will cause the sliding plate 4 to move upward, so that the sliding plate 4 moves upward between the two limiting grooves 3. At the same time, the upward movement of the sliding plate 4 will cause the sample to move upward, and several drainage holes 5 can drain the sample on the sliding plate 4 until all the sample on the sliding plate 4 moves to the top of the thawing water. At this time, the personnel can take out the thawed sample. This ensures that the personnel do not need to put their hands into the thawing water when taking out the thawed sample, which makes it easy for the personnel to take out the thawed sample and will not cause injury to the personnel's hands.

[0053] A rotating groove 13 is formed inside the support rod 8 and located below the slide groove 9. A worm gear 14 is rotatably installed inside the rotating groove 13. The top end of the worm gear 14 extends through the top of the rotating groove 13 into the slide groove 9 and is coaxially connected to the threaded rod 12. A worm 15 is meshed and installed on one side of the worm gear 14 and inside the rotating groove 13. One end of the worm 15 extends through one side of the rotating groove 13 to the outside and is fixedly installed with a handle 16.

[0054] Rotating handle 16 causes worm gear 15 to rotate, which in turn drives worm wheel 14 to rotate. Worm wheel 14 then drives threaded rod 12 to rotate. Threaded rod 12 rotates, causing moving plate 10 to move upwards. Moving plate 10 upwards drives motor 11 upwards, which in turn drives rotating rod 6 upwards. Rotating rod 6 then drives sliding plate 4 upwards, causing sliding plate 4 to move upwards between the two limiting grooves 3. Simultaneously, the upward movement of sliding plate 4 causes the sample to move upwards. Several drainage holes 5 drain water from the sample on sliding plate 4 until all the sample on sliding plate 4 is above the thawing water. At this point, personnel can remove the thawed sample without having to put their hands into the thawing water, ensuring easy removal of the thawed sample without injury to the personnel's hands.

[0055] Example 3:

[0056] This embodiment provides a sample thawing device for food testing. In addition to the technical solutions of the above embodiments, it also has the following technical features: the threaded rod 12 is threadedly connected to the moving plate 10, the top end of the worm gear 14 is rotatably connected to the slide groove 9, and the worm 15 is rotatably connected to the rotating groove 13.

[0057] Specifically, it ensures that the rotation of the threaded rod 12 can drive the moving plate 10 to move up and down, ensures that the top of the worm wheel 14 can rotate normally in the slide groove 9, and ensures that the worm 15 can rotate normally in the rotating groove 13.

In addition to the technical solutions of the above embodiments, it also has the following technical features: a plurality of stirring rods 7 are distributed in a ring at equal intervals, and the cross-section of the rotating rod 6 is T-shaped.

[0063] Among these measures, it is ensured that several stirring rods 7 can stir the sample more evenly and that the rotating rod 6 will not fall off the sliding plate 4.

[0064] Example 6:

[0065] This embodiment provides a sample thawing device for food testing. In addition to the technical solutions of the above embodiments, it also has the following technical features: the cross-section of the chute 9 is T-shaped, and a number of drainage holes 5 are distributed in an annular pattern at equal intervals.

[0066] In this way, it is ensured that the movable plate 10 will not fall out of the slide groove 9, and that the several drainage holes 5 can drain all the thawing water on the sliding plate 4.

During the heating process, personnel can observe the temperature of the thawing water in the thawing tank 2 by observing the thermometer 19. The temperature of the thawing water can be precisely controlled according to the sample that needs to be thawed, so that the sample thawing speed can reach the fastest speed without damaging the sample, thus ensuring that the sample thawing efficiency can be accelerated.

[0068] Subsequently, personnel can place the sample into the thawing water in the thawing tank 2. Simultaneously, the motor 11 can be started. The output shaft of the motor 11 will drive the rotating rod 6 to rotate, causing the rotating rod 6 to rotate on the sliding plate 4. The rotation of the rotating rod 6 will also drive several stirring rods 7 to rotate, stirring the sample in the thawing tank 2 and ensuring sufficient contact between the sample and the thawing water, thereby accelerating the thawing process. After thawing is complete, personnel can turn off the motor 11 and turn the handle 16. Turning the handle 16 will drive the worm gear 15 to rotate. Under the meshing action, the rotation of the worm gear 15 will drive the worm wheel 14 to rotate, which in turn will drive the threaded rod 12 to rotate. Under the action of the thread, the threaded rod... Rotation of 12 will cause the moving plate 10 to move upward, which in turn will cause the motor 11 to move upward, which in turn will cause the rotating rod 6 to move upward, which in turn will cause the sliding plate 4 to move upward, so that the sliding plate 4 moves upward between the two limiting grooves 3. At the same time, the upward movement of the sliding plate 4 will cause the sample to move upward, and several drainage holes 5 can drain the sample on the sliding plate 4 until all the sample on the sliding plate 4 moves above the thawing water. At this time, the personnel can take out the thawed sample. This ensures that the personnel do not need to put their hands into the thawing water when taking out the thawed sample, which makes it easy for the personnel to take out the thawed sample and will not cause injury to the personnel's hands.
