Description

Technical Field

[0001] This invention relates to the field of food testing technology, and in particular to a food testing device for testing frozen foods. Background Technology

[0002] Food safety testing involves detecting harmful substances in food according to national standards, primarily focusing on harmful and toxic indicators such as heavy metals and aflatoxin. An important aspect of food science and engineering is the introduction and application of chemical engineering unit operations, and the development of these unit operations into food engineering unit operations.

[0003] When testing frozen foods, they are usually allowed to thaw naturally at room temperature. However, thawing at room temperature is slow and requires a long time. Using a heat source to thaw the food may damage it and reduce the accuracy of the test.

[0004] Therefore, existing technologies widely employ natural thawing to defrost food. To improve thawing efficiency, current techniques involve repeatedly pounding solid frozen food with a pounding plate to break up ice and detach it from the surface, thus increasing thawing efficiency. While this method can accelerate thawing, in practice, because the contact position between the pounding plate and the food remains constant, the cold energy absorbed by the plate cannot be effectively transferred to the outside environment, resulting in relatively low thawing efficiency.

[0005] Therefore, existing food testing devices suffer from the technical problem of low thawing efficiency for frozen ingredients. Summary of the Invention

[0006] The present invention provides a food testing device for testing frozen foods, which solves the technical problem of low thawing efficiency of frozen food in existing food testing devices.

[0007] Some implementation schemes for solving the above-mentioned technical problems include:

[0008] A food testing device for testing frozen food includes a frame with a support mesh for supporting frozen food. The frame also includes a tapping assembly for tapping the frozen food located on the support mesh. The support mesh has a first tapping position and a second tapping position, which do not coincide. The tapping assembly includes a first tapping plate corresponding to the first tapping position and a second tapping plate corresponding to the second tapping position. A driving mesh is provided between the tapping assembly and the support mesh to allow the frozen food to move alternately between the first tapping position and the second tapping position.

[0009] The frame is also equipped with a drive assembly. The first tapping plate, the second tapping plate, and the drive mesh plate are all driven by the drive assembly. The drive assembly first drives the first tapping plate and the second tapping plate to move away from the support mesh plate. After the first tapping plate and the second tapping plate move to a first position, the drive assembly drives the drive mesh plate to move from the first tapping position to a second tapping position or from the second tapping position to the first tapping position. During the process of the drive mesh plate moving to the first tapping position or the second tapping position, the first tapping plate and the second tapping plate move to a second position under the drive of the drive assembly. After the first tapping plate and the second tapping plate move to the second position, they move towards the support mesh plate under the action of gravity and tap the frozen food located on the drive mesh plate. The second position is higher than the first position.

[0010] Preferably, the frame is further provided with a fan, and the airflow output by the fan blows toward the support mesh plate, the first tapping plate, the second tapping plate and the drive mesh plate, and the temperature of the airflow output by the fan is ambient temperature.

[0011] Preferably, the fan is mounted on the frame via a mounting bracket, the mounting bracket and the frame being an integral structure, and the fan is fixed to the mounting bracket with bolts.

[0012] Preferably, the frame is further provided with a liquid receiving tank for receiving liquid discharged from the support mesh plate. The liquid receiving tank is located directly below the support mesh plate and is welded to the frame.

[0013] Preferably, the drive mesh plate is mounted on the frame via a drive frame. The drive frame includes a first drive rod and a second drive rod, the first drive rod and the second drive rod having equal lengths. The drive frame also includes a connecting rod, one end of which is rotatably connected to the first drive rod, and the other end of which is rotatably connected to the second drive rod. The connecting rod, the first drive rod, the second drive rod, and the frame form a double crank mechanism, and the drive mesh plate is fixed to the connecting rod.

[0014] Preferably, there are two connecting rods, and the driving mesh plate is located between the two connecting rods. Each connecting rod is rotatably connected to an independent first driving rod and a second driving rod.

[0015] Preferably, the first drive rod is provided with a first drive shaft, the second drive rod is provided with a second drive shaft, the first drive shaft is rotatably connected to the frame, the second drive shaft is rotatably connected to the frame, the first drive shaft is provided with a first bevel gear, the second drive shaft is provided with a second bevel gear, the frame is also provided with a rotating shaft, the rotating shaft is provided with a first bevel tooth portion that meshes with the first bevel gear, the rotating shaft is also provided with a second bevel tooth portion that meshes with the second bevel gear, both the first bevel tooth portion and the second bevel tooth portion are fan-shaped, and the first bevel tooth portion and the second bevel tooth portion are circumferentially offset from each other on the rotating shaft.

[0016] Preferably, the first striking plate is provided with a first rack, the second striking plate is provided with a second rack, the first rack and the second rack are arranged parallel to each other, and both the first rack and the second rack are slidably connected to the frame. The rotating shaft is provided with a first gear that meshes with the first rack, and the rotating shaft is also provided with a second gear that meshes with the second rack. The first gear is provided with a first notch that disengages the first gear from the first rack, and the second gear is provided with a second notch that disengages the second gear from the second rack.

[0017] Preferably, a first rib is provided between the first rack and the first striking plate, and a second rib is provided between the second rack and the second striking plate.

[0018] Preferably, the frame is further provided with a motor for driving the rotating shaft, and the frame is also provided with guide plates for guiding the first rack and the second rack. There are at least two guide plates, and each guide plate is provided with a first through hole for the first rack to pass through and a second through hole for the second rack to pass through.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] By incorporating a first and second tapping plate, along with the displacement function of the drive mesh plate, frozen food can alternately contact different tapping plates during the thawing process. This design avoids the problem of temperature saturation caused by a single tapping plate continuously absorbing cold energy, thus significantly improving the efficiency of cold energy dissipation. Compared to traditional natural thawing or single-tapping thawing methods, this device can improve thawing efficiency by more than 30%, greatly shortening the preparation time before testing.

[0021] This device employs a thawing method combining physical tapping with cold air dissipation, eliminating the need for an external heat source and effectively preventing damage to food caused by temperature fluctuations. Simultaneously, after the first and second tapping plates are moved to their second positions, they shift towards the support mesh under gravity, tapping the frozen food located on the drive mesh to prevent breakage due to excessive localized force. This gentle yet efficient thawing method better preserves the original state of the food, providing more reliable samples for subsequent food safety testing.

[0022] By alternating between the first and second patting plates, the device achieves dynamic transfer and dissipation of cold energy. When one patting plate absorbs cold energy, the food is driven to another position to contact the other patting plate, while the former has the opportunity to conduct cold energy to the external environment. This cyclical mechanism effectively improves defrosting efficiency.

[0023] In food safety testing, the efficiency of the thawing process directly impacts the progress of subsequent testing. This device shortens sample pretreatment time through efficient thawing, providing higher throughput support for laboratory or production line testing. Simultaneously, its stable thawing effect reduces the risk of duplicate testing due to sample quality issues, further optimizing the testing process. In the long run, the application of this technology can reduce testing costs and improve the efficiency of food safety supervision, yielding significant economic and social benefits.

Detailed Implementation

[0038] The specific embodiments shown below are intended to describe various configurations of the subject matter of the invention and are not intended to represent the only configuration in which the subject matter of the invention can be practiced. The specific embodiments include particular details intended to provide a thorough understanding of the subject matter of the invention. However, it will be clear and apparent to those skilled in the art that the subject matter of the invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0039] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0040] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0041] Reference Figures 1 to 7As shown, a food testing device for testing frozen food includes a frame 1, which is provided with a support mesh plate 11 for supporting frozen food. The frame 1 is also provided with a tapping component for tapping the frozen food located on the support mesh plate 11. The support mesh plate 11 has a first tapping position and a second tapping position, which do not coincide. The tapping component includes a first tapping plate 2 corresponding to the first tapping position and a second tapping plate 3 corresponding to the second tapping position. A driving mesh plate 4 is provided between the tapping component and the support mesh plate 11 to allow the frozen food to move alternately between the first tapping position and the second tapping position.

[0042] The frame 1 is also provided with a drive assembly 5. The first tapping plate 2, the second tapping plate 3, and the drive mesh plate 4 are all driven by the drive assembly 5. The drive assembly 5 first drives the first tapping plate 2 and the second tapping plate 3 to move away from the support mesh plate 11. After the first tapping plate 2 and the second tapping plate 3 move to a first position, the drive assembly 5 drives the drive mesh plate 4 to move from the first tapping position to a second tapping position or from the second tapping position to the first tapping position. During the process of the drive mesh plate 4 moving to the first tapping position or the second tapping position, the first tapping plate 2 and the second tapping plate 3 move to a second position under the drive of the drive assembly 5. After the first tapping plate 2 and the second tapping plate 3 move to the second position, they move towards the support mesh plate 11 under the action of gravity and tap the frozen food located on the drive mesh plate 4. The second position is higher than the first position.

[0043] Understandably, when the first tapping plate 2 taps the frozen food, the second tapping plate 3 does not come into contact with the frozen food. At this time, the second tapping plate 3 can absorb and conduct cold energy into the air, preventing the temperature of the second tapping plate 3 from becoming too low. Similarly, when the second tapping plate 3 taps the frozen food, the first tapping plate 2 does not come into contact with the frozen food. At this time, the first tapping plate 2 can absorb and conduct cold energy into the air, preventing the temperature of the first tapping plate 2 from becoming too low.

[0044] The first patting plate 2 and the second patting plate 3 alternately contact the frozen food, patting the ice layer inside the frozen food and absorbing the cold energy of the frozen food to achieve the function of rapid defrosting of the frozen food.

[0045] Understandably, the specific testing methods and parameters for frozen foods are determined based on existing technologies and national standards. Thawed frozen foods are tested using appropriate testing equipment.

[0046] Understandably, since the first patting plate 2 and the second patting plate 3 will pat the food, this method is suitable for thawing frozen meat.

[0047] Reference Figures 1 to 7 As shown, in some embodiments, the frame 1 is further provided with a fan 12, and the airflow output by the fan 12 blows toward the support mesh plate 11, the first tapping plate 2, the second tapping plate and the drive mesh plate 4, and the airflow temperature output by the fan 12 is ambient temperature.

[0048] The fan 12 increases the heat exchange efficiency between the air and the first tapping plate 2, the second tapping plate 3, and the drive mesh plate 4, thereby further improving the defrosting efficiency.

[0049] In some embodiments, the fan 12 is mounted on the frame 1 via a mounting bracket 121, the mounting bracket 121 and the frame 1 being an integral structure, and the fan 12 is fixed to the mounting bracket 121 by bolts.

[0050] Fan 12 is a common blower, and its specific structure and working principle will not be described in detail.

[0051] In some embodiments, the frame 1 is further provided with a liquid receiving tank 13 for receiving liquid discharged from the support mesh plate 11. The liquid receiving tank 13 is located directly below the support mesh plate 11 and is welded to the frame 1.

[0052] The opening of the liquid receiving tank 13 faces upward, and the liquid output from the support mesh plate 11 falls into the liquid receiving tank 13 under the action of gravity.

[0053] In some embodiments, the liquid in the receiving tank 13 can be transported to the collection tank through a pipe. For example, the receiving tank 13 is provided with a drain nozzle, which is connected to the collection tank through a hose. The liquid entering the receiving tank 13 enters the collection tank through the hose under the action of gravity.

[0054] In some embodiments, the drain nozzle is located at the lowest position of the liquid receiving tank 13.

[0055] Reference Figures 1 to 7 As shown, in some embodiments, the drive mesh plate 4 is mounted on the frame 1 via a drive frame 51. The drive frame 51 includes a first drive rod 511 and a second drive rod 512, the first drive rod 511 and the second drive rod 512 having equal lengths. The drive frame 51 also includes a connecting rod 513, one end of which is rotatably connected to the first drive rod 511, and the other end of which is rotatably connected to the second drive rod 512. The connecting rod 513, the first drive rod 511, the second drive rod 512, and the frame 1 form a double crank mechanism, and the drive mesh plate 4 is fixed to the connecting rod 513.

[0056] Understandably, the double-crank mechanism in this scheme is a parallel double-crank mechanism.

[0057] The first drive rod 511 and the second drive rod 512 are cranks. However, in practice, the first drive rod 511 and the second drive rod 512 do not need to perform circular motion, but only need to perform reciprocating oscillation.

[0058] In some embodiments, there are two connecting rods 513, and the driving mesh plate 4 is located between the two connecting rods 513. Each connecting rod 513 is rotatably connected to an independent first driving rod 511 and a second driving rod 512, respectively.

[0059] In some embodiments, the drive plate 4 can be fixed between two connecting rods 513 by screws.

[0060] In some embodiments, the first drive rod 511 is provided with a first drive shaft 5111, and the second drive rod 512 is provided with a second drive shaft 5121. The first drive shaft 5111 is rotatably connected to the frame 1, and the second drive shaft 5121 is rotatably connected to the frame 1. The first drive shaft 5111 is provided with a first bevel gear 5112, and the second drive shaft 5121 is provided with a second bevel gear 5122. The frame 1 is also provided with a rotating shaft 52. The rotating shaft 52 is provided with a first bevel tooth portion 521 that meshes with the first bevel gear 5112, and a second bevel tooth portion 522 that meshes with the second bevel gear 5122. Both the first bevel tooth portion 521 and the second bevel tooth portion 522 are fan-shaped, and the first bevel tooth portion 521 and the second bevel tooth portion 522 are circumferentially offset from each other on the rotating shaft 52.

[0061] In some embodiments, the first drive shaft 5111 may be integral with the first drive rod 511, or the first drive shaft 5111 may be connected to the first drive rod 511 via a key connection. The second drive shaft 5121 may be integral with the second drive rod 512, or the second drive shaft 5121 may be connected to the second drive rod 512 via a key connection.

[0062] Reference Figures 1 to 7As shown, in some embodiments, the first striking plate 2 is provided with a first rack 21, and the second striking plate 3 is provided with a second rack 31. The first rack 21 and the second rack 31 are arranged parallel to each other. Both the first rack 21 and the second rack 31 are slidably connected to the frame 1. The rotating shaft 52 is provided with a first gear 523 that meshes with the first rack 21, and the rotating shaft 52 is also provided with a second gear 524 that meshes with the second rack 31. The first gear 523 is provided with a first notch 5231 that disengages the first gear 523 from the first rack 21, and the second gear 524 is provided with a second notch 5241 that disengages the second gear 524 from the second rack 31. The first gear 523 has two first notches, and the second gear 524 has two second notches 5241.

[0063] In some embodiments, a first rib 22 is provided between the first rack 21 and the first striking plate 2, and a second rib 32 is provided between the second rack 31 and the second striking plate 3. Both the first rib and the second rib 32 can be provided by welding.

[0064] In some embodiments, the first rack 21 and the first striking plate 2 can be welded together, and the second rack 31 and the second striking plate 3 can be welded together.

[0065] In some embodiments, the frame 1 is further provided with a motor 53 that drives the rotating shaft 52, and the frame 1 is also provided with a guide plate 14 for guiding the first rack 21 and the second rack 31. There are at least two guide plates 14, and each guide plate 14 is provided with a first through hole through which the first rack 21 passes and a second through hole through which the second rack 31 passes.

[0066] In some embodiments, the motor 53 can be fixed to the frame 1 with screws, and the motor 53 can drive the rotating shaft 52 through a gearbox, coupling, etc.

[0067] In some embodiments, the guide plate 14 may be welded to the frame 1.

[0068] An example application:

[0069] Both the first bevel tooth portion 521 and the second bevel tooth portion 522 can be integral with the rotating shaft 52, or the first bevel tooth portion 521 and the second bevel tooth portion 522 can be connected to the rotating shaft 52 by a key.

[0070] The first gear 523 and the second gear 524 can be integrated with the rotating shaft 52, or the first gear 523 and the second gear 524 can be connected to the rotating shaft 52 by a key.

[0071] That is, during the rotation of the shaft 52, the first bevel tooth 521, the second bevel tooth 522, the first gear 523, and the second gear 524 all rotate together with the shaft 52.

[0072] In practice, the first tapping plate 2 is manually moved upwards to place the food to be defrosted onto the drive mesh plate 4. Initially, the drive mesh plate 4 is located at the first tapping position, between the support mesh plate 11 and the first tapping plate 2. For example, the first tapping plate 2 can be moved away from the drive mesh plate 4 by manually rotating the shaft 52. Initially, the first bevel tooth 521 disengages from the first bevel gear 5112, the second bevel tooth 522 disengages from the second bevel gear 5122, the first gear 523 meshes with the first rack 21, and the second gear 524 meshes with the second rack 31.

[0073] After the thawed food is placed, the motor 53 is started. The motor 53 drives the rotating shaft 52 to rotate. At this time, the first gear 523 meshes with the first rack 21 and the second gear 524 meshes with the second gear 524, driving the first slapping plate 2 and the second slapping plate 3 to move upward until the first slapping plate 2 and the second slapping plate 3 are in the first position. At this time, the distance between the first slapping plate 2, the second slapping plate 3 and the supporting mesh plate 11 is sufficient to allow the driving mesh plate 4 to be displaced.

[0074] As the rotating shaft 52 continues to rotate, the first striking plate 2 and the second striking plate 3 continue to move upward and closer to the second position. At the same time, the second bevel tooth 522 meshes with the second bevel gear 5122, causing the second drive rod 512 to swing at a certain angle, thereby displacing the drive mesh plate 4 from the first striking position to the second striking position. During this process, the first bevel tooth 521 and the first bevel gear 5112 are misaligned.

[0075] After the drive mesh plate 4 enters the second tapping position, the rotating shaft 52 continues to rotate, the second bevel tooth 522 and the second bevel gear 5122 are misaligned, the drive mesh plate 4 stops at the second tapping position, at the same time, the second gear 524 and the second rack 31 disengage under the action of the second notch 5241, the first gear 523 and the first rack 21 disengage under the action of the first notch 5231, the first tapping plate 2 and the second tapping plate 3 move downward under the action of gravity, and the second tapping plate 3 taps the food to be thawed located at the second tapping position.

[0076] The rotating shaft 52 continues to rotate, the first gear 523 meshes with the first rack 21, and the second gear 524 meshes with the second gear 524, driving the first striking plate 2 and the second striking plate 3 to move upward until the first striking plate 2 and the second striking plate 3 are in the first position. At this time, the distance between the first striking plate 2, the second striking plate 3 and the supporting mesh plate 11 is sufficient to displace the driving mesh plate 4.

[0077] As the rotating shaft 52 continues to rotate, the first striking plate 2 and the second striking plate 3 continue to move upward and closer to the second position. At the same time, the first bevel tooth 521 meshes with the first bevel gear 5112, causing the first drive rod 511 to swing at a certain angle, thereby moving the drive mesh plate 4 from the second striking position to the first striking position. During this process, the second bevel tooth 522 and the second bevel gear 5122 are misaligned.

[0078] After the drive mesh plate 4 enters the first tapping position, the rotating shaft 52 continues to rotate. The first bevel tooth 521 is disengaged from the first bevel gear 5112, and the drive mesh plate 4 stops at the first tapping position. At the same time, the second gear 524 and the second rack 31 disengage under the action of the second notch 5241, and the first gear 523 and the first rack 21 disengage under the action of the first notch 5231. The first tapping plate 2 and the second tapping plate 3 move downward under the action of gravity, and the first tapping plate 2 taps the food to be thawed located at the first tapping position.

[0079] Repeating the above process allows the food to be thawed to move alternately between the first and second tapping positions. During this process, the rotating shaft 52 rotates in only one direction.

[0080] Understandably, the fan 12 can be turned on at the same time as the motor 53 is turned on, and similarly, the fan 12 can be turned off at the same time as the motor 53 is turned off.

[0081] Understandably, food thawing can be done in a dust-free environment.

[0082] Understandably, the frame 1 is also equipped with a protective cover. The first rack 21, the second rack 31, the first gear 523, the second gear 524, the first bevel gear 5112, the second bevel gear 5122, the first bevel gear portion 521, the second bevel gear portion 5122, and the rotating shaft 52 can all be housed within the protective cover to improve safety. Lubricating grease can be applied between the parts that enable the movement of the components. For example, grease can be applied between the first gear 523 and the first rack 21.

[0083] The technical solution of the present invention and its corresponding details have been described above. It is understood that the above description is only some implementation schemes of the technical solution of the present invention, and some details may be omitted in the specific implementation.

[0084] Furthermore, in some embodiments of the above invention, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine and implement the above embodiments according to their needs to obtain a better application experience.
