Description

Technical Field

[0001] The present invention belongs to the technical field of meat moisture detection, and in particular relates to a meat moisture detection device and a detection method thereof. Background Art

[0002] As living standards improve in both urban and rural areas, the consumption of fresh meat from livestock and poultry is increasing, and people's expectations for fresh meat quality are becoming increasingly stringent. Moisture content directly impacts the processing, storage, trade, and consumption of fresh meat. Excessive moisture content in meat promotes bacterial and mold growth, easily causing meat spoilage. Dehydration and shrinkage not only cause meat to lose weight, resulting in direct economic losses, but also affect its color, flavor, and texture, and can cause fat oxidation. Therefore, moisture testing of meat is particularly important. In this area, drying (heating evaporation) is widely used due to its simplicity and reliability.

[0003] For example, the utility model with publication number CN211453237U discloses a meat moisture detection device, comprising a lower base, a workbench installed on the upper surface of the lower base, a tray rack provided on the upper surface of the workbench, a bottom weighing plate installed below the tray rack, a heating plate installed inside the bottom weighing plate directly below the tray rack, a bottom support column installed at the lower end of the inner tray, and a second rotating motor installed at the lower end of the bottom weighing plate. By providing the bottom support column at the bottom end of the inner tray, a whole piece of meat can be placed on the bottom support column, and the gap between the bottom support columns can facilitate the entry of heat, thereby accelerating the evaporation of moisture in the meat. The first rotating motor is used to drive the rotating shaft to rotate the inner tray as a whole, so that the meat is heated evenly, the detection efficiency is accelerated, and frequent temperature fluctuations are avoided to prevent the meat from leaking water, thereby affecting the detection results.

[0004] In actual applications, existing meat moisture detection devices have a significant problem of uneven heating leading to detection errors. Traditional ovens rely on forced convection heating. Due to the limitations of the cavity structure, the hot air flow rate in the corner area is reduced, and the hot air circulation is uneven, resulting in differences in the sample drying rate. For example, the sample in the center area may be completely dry, while the sample at the edge still contains residual moisture, affecting the final detection accuracy; at the same time, when meat is rapidly dehydrated at high temperature, the surface moisture quickly evaporates to form a dense hard shell, which hinders the diffusion of internal moisture, resulting in low test results, easily leading to moisture loss on the meat surface, affecting the taste.

[0005] Therefore, a meat moisture detection device and a detection method thereof are proposed to solve the problems raised in the background art. Summary of the Invention

The placement plate is used to place the meat to be tested, and a gravity sensor is provided inside the placement plate for monitoring the gravity of the meat.

[0010] Preferably, the driving assembly includes a rotating disk, a driving disk located on one side of the rotating disk for driving the rotating disk to rotate, and a control motor fixedly arranged at the center of the driving disk.

[0011] Preferably, a plurality of limiting grooves distributed in a circular array are provided on the surface of the rotating disk, and a rotating rod fixedly connected to the center of the connecting circular plate is fixedly provided at the center of the rotating disk; A crescent disk is fixedly provided on the top of the driving disk, and the edge of the crescent disk is engaged with the edge of the rotating disk.

[0012] Preferably, the spray assembly includes at least three connecting pipes, an air outlet box fixedly arranged at the bottom of the connecting pipe, a plurality of spray pipes fixedly installed at the bottom of the air outlet box, and a transmission component arranged inside the spray pipe; The transmission component is used to uniformly transmit the heat inside the evaporation box to the installation box, and the connecting pipe is connected to the evaporation box.

[0013] Preferably, the transmission component includes a fixing frame fixedly arranged on the inner walls of the plurality of spray pipes, a center rod fixedly arranged at the center of the fixing frame, a plurality of inner fan blades sleeved on the center rod, a connecting plate fixedly arranged on the inner fan blades, and an outer fan blade fixedly arranged on the connecting plate.

[0014] Preferably, the plurality of inner blades are distributed in a circular array, and the outer blades are spiral and are sleeved on the outside of the spray pipe.

[0015] Preferably, the drying assembly includes an L-shaped plate fixedly arranged on the inner wall of the installation box and a drying head fixedly arranged at the bottom of the L-shaped plate.

[0016] A meat moisture detection method, comprising: sampling, weighing and recording, heating and drying, and comparative weighing and calculation. Step 1: Take a representative meat sample, remove visible fascia and fat, and mince into granules; Step 2: Use a gravity sensor and a high-precision balance to record the initial mass; Step 3: Spread the sample flat on the placement tray and place it inside the placement box. Use the spray component, drying component and drive component to achieve uniform heating of the sample and remove the moisture inside. Step 4: Place the sample on a tray and let it cool.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates uniform heating and drying of meat by arranging the coordination of structures such as a spraying component, a placement plate and a driving component. The height of the placement box is adjusted by an electric cylinder, and the pre-processed meat sample is spread on a placement plate with a gravity sensor to record the initial mass. The driving component drives the placement plate to rotate intermittently in the temperature control system, and passes through multi-stage decreasing temperature heating zones and drying zones in sequence. Gradual dehydration avoids surface crusting, and the precipitated moisture is collected through a guide groove and weighed again after cooling. The moisture content is automatically calculated through the mass difference to achieve accurate detection. This solves the problem that when using the heating method to detect moisture in meat, the oven relies on forced convection heating, the meat is placed relatively fixedly, and the hot air circulation is uneven, resulting in differences in sample drying rates and affecting the final detection accuracy.

[0018] The present invention facilitates the intermittent rotation of the placement plate to adapt to different heating temperatures by arranging the coordination of structures such as a rotating plate, a driving plate and a control motor. The motor drives the crescent plate and the limit rod structure to drive the intermittent rotation of the rotating plate, so that multiple placement plates pass through the heating sections and drying sections of different temperature zones in turn, thereby realizing zoned progressive heating and dehydration of meat samples and ensuring the uniformity and accuracy of moisture detection.

[0019] The present invention facilitates the segmented heating of meat by arranging the coordination of structures such as the spray pipe, the transmission component and the drying assembly, thereby making the heat transmission more uniform. The hot steam generated by the evaporator is transported to the air outlet box through the connecting pipe and then released evenly by the spray pipe. During the transmission process, the inner and outer fan blades rotate synchronously to stir the airflow, accelerate heat exchange and improve the uniformity of heat distribution, thereby achieving rapid and efficient heating of meat.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 9 As shown, the present invention provides a meat moisture detection device, comprising a supporting base plate 1, a plurality of connecting frames 11 arranged in a circular array are fixedly provided on the top of the supporting base plate 1, and an electric cylinder 12 is fixedly provided at the center of the top of the supporting base plate 1; The installation box 2 is fixedly mounted on the top of the connecting frame 11 and is circular in shape with the supporting base plate 1. A plurality of evaporation boxes 21 arranged in a circular array are provided on the outer wall of the installation box 2. A spray assembly 22 and a drying assembly 23 are provided inside the installation box 2. A sealing cover 3 is slidably abutted against the top of the installation box 2. A placement box 4 is slidably arranged inside the mounting box 2. The bottom of the placement box 4 is fixedly connected to the top of the electric cylinder 12. A placement mechanism 5 is provided inside the placement box 4 for placing meat to be processed. The placement mechanism 5 includes a plurality of placement plates 51 distributed in a circular array, a connecting circular plate 52 fixedly arranged at the center of the plurality of placement plates 51, a driving assembly 53 located at the bottom of the placement box 4, and a plurality of collection boxes 54 slidably arranged inside the placement box 4. The driving assembly 53 is used to drive the connecting circular plate 52 to rotate intermittently. A plurality of partitions distributed in a circular array are fixedly arranged on the inner wall of the placement box 4. A rotation groove 41 is formed on each of the plurality of partitions. A plurality of collection grooves 42 are formed on the outer wall of the placement box 4 away from the rotation groove 41. The collection boxes 54 are slidably connected to the collection grooves 42. A plurality of lower water tanks 511 are provided at the bottom of the placing plate 51 , and the placing plate 51 rotates along the rotating groove 41 . The placing plate 51 is used to place the meat to be tested. A gravity sensor is provided inside the placing plate 51 for monitoring the gravity of the meat.

[0024] The above scheme is adopted: by using the electric cylinder 12 to move the long placement box 4 along the installation box 2, and cooperating with the placement mechanism 5 to place the meat to be tested, specifically, the meat is laid on the placement tray 51, and the initial weight of the meat is recorded by the gravity sensor. The driving component 53 drives the connecting circular plate 52 and the placement tray 51 to rotate intermittently in the rotating groove 41, and at the same time cooperates with the evaporation box 21, the spraying component 22 and the drying component 23 on the installation box 2 to heat and dry the small meat in the placement tray 51 in turn to remove the internal moisture. During the removal process, the temperature in each evaporation box 21 decreases in sequence to avoid the problem that when the meat is quickly dehydrated at high temperature, the surface moisture quickly evaporates to form a dense hard shell, which hinders the internal moisture from diffusing outward and causes low test results. After heating, the excess moisture can fall into the collection box 54 along the lower water tank 511 to prevent sewage from polluting the device. After treatment, it is allowed to stand in the placement tray 51 to cool naturally. After cooling, the processed meat is weighed by the gravity sensor, and the moisture content is calculated to achieve moisture detection of the meat.

[0025] like Figure 9 As shown, the driving assembly 53 includes a rotating disk 531, a driving disk 532 located on one side of the rotating disk 531 for driving the rotating disk 531 to rotate, and a control motor 533 fixedly arranged at the center of the driving disk 532; The surface of the rotating disk 531 is provided with a plurality of limiting grooves 5311 distributed in a circular array. A rotating rod 5312 fixedly connected to the center of the connecting circular plate 52 is fixedly provided at the center of the rotating disk 531. A crescent disk 5321 is fixedly provided on the top of the driving disk 532, and the edge of the crescent disk 5321 engages with the edge of the rotating disk 531. A limiting rod 5322 is fixedly provided on the side of the top of the driving disk 532 away from the crescent disk 5321, and the limiting rod 5322 is engaged with the limiting groove 5311.

[0026] The above scheme is adopted: the placement plate 51 and the connecting circular plate 52 are intermittently rotated by using the driving component 53, so as to achieve uniform heating of the meat in different zones. Specifically, the driving plate 532 is driven to rotate by using the control motor 533, and the crescent plate 5321 and the limiting rod 5322 on the driving plate 532 are driven to rotate synchronously. The limiting rod 5322 is engaged with the limiting groove 5311, which can drive the rotating plate 531 to rotate intermittently, and then drive the connecting circular plate 52 connected to it to rotate intermittently, so that multiple placement plates 51 are rotated along the rotating groove 41, and the meat in multiple placement plates 51 is rotated to the evaporator 21 with different temperatures at one time, and is heated in sections by using the spraying component 22, and is dried at the same time in conjunction with the drying component 23.

[0027] like Figures 4 to 6 As shown, the spray assembly 22 includes at least three connecting pipes 221, an air outlet box 222 fixedly installed at the bottom of the connecting pipe 221, a plurality of spray pipes 223 fixedly installed at the bottom of the air outlet box 222, and a transmission component 224 arranged inside the spray pipe 223; The transmission component 224 is used to uniformly transmit the heat inside the evaporation box 21 to the installation box 2. The connecting pipe 221 is connected to the evaporation box 21. The transmission component 224 includes a fixing frame 2241 fixedly arranged on the inner wall of the plurality of spray pipes 223, a central rod 2242 fixedly arranged at the center of the fixing frame 2241, a plurality of inner blades 2243 sleeved on the central rod 2242, a connecting plate 2244 fixedly arranged on the inner blades 2243, and an outer blade 2245 fixedly arranged on the connecting plate 2244. The plurality of inner blades 2243 are distributed in a circular array, and the outer blades 2245 are spiral-shaped and sleeved on the outside of the spray pipe 223. The drying assembly 23 includes an L-shaped plate 231 fixedly disposed on the inner wall of the installation box 2 and a drying head 232 fixedly disposed at the bottom of the L-shaped plate 231 .

[0028] The above scheme is adopted: through the cooperation of the evaporator 21, the connecting pipe 221 and the transmission component 224, the effect of uniformly transmitting the heat inside the evaporator 21 to the inside of the placement box 4 is achieved. When evaporating inside the evaporator 21, the hot steam will pass through the air outlet box 222 along the connecting pipe 221 and then be transmitted to the top of the bottom placement plate 51 by the spray pipe 223. During the transmission process, the inner fan blades 2243 will be driven to rotate along the central rod 2242, and the heat inside the air outlet box 222 will be transmitted to the outside of the spray pipe 223, thereby driving the connecting plate 2244 to rotate synchronously. At this time, the outer fan blades 2245 are rotated to stir the heat transmitted to the outside of the spray pipe 223, which is convenient for air circulation, accelerates heat transmission, and makes it more evenly distributed, so as to facilitate rapid heating of the meat on the placement plate 51.

[0029] A meat moisture detection method, comprising: sampling, weighing and recording, heating and drying, and comparative weighing and calculation. Step 1: Take a representative meat sample, remove visible fascia and fat, and mince into granules; Step 2: Use a gravity sensor and a high-precision balance to record the initial mass; Step 3: Spread the sample flat on the placement tray 51 and place it inside the placement box 4. Use the spraying component 22, the drying component 23 and the driving component 53 to achieve uniform heating of the sample and remove the moisture inside. Step 4: Place the sample in a tray 51 and let it cool. After reaching room temperature, weigh it and calculate the water content.

[0030] The working principle and usage process of the present invention are as follows: when using the device, meat is sampled, visible fascia and fat are removed, and the meat is minced into granules, which are evenly spread on the placement tray 51. The gravity sensor at the bottom of the placement tray 51 is used in conjunction with the external control module to record the initial mass of the sample. The evaporation box 21 is used to transfer the heat in the evaporation box 21 to the interior of the placement box 4 through the spray assembly 22. The driving disk 532 is driven to rotate by the control motor 533, so that the rotating disk 531 rotates intermittently. During the rotation process, the samples placed on multiple placement trays 51 are rotated to one side of the evaporation box 21 controlled by different temperatures at one time. The spray assembly 22 is used to heat the samples in the placement tray 51 from high to low, and finally rotated to the drying assembly 23. The samples are dried by the cooperation of the L-shaped plate 231 and the drying head 232. After drying, they are left to stand until they cool down. The cooled samples are then weight tested and the moisture content is calculated, thereby completing the moisture detection of the meat.
