Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drip loss determination, in particular to a device and method for continuously determining drip loss of meat samples. BACKGROUND

[0002] In view of the small range of intensive breeding of steel geese, the high incidence, the lack of development and utilization of germplasm resources, the poor adaptability of Zhexi White Geese to high altitudes and low temperatures, and the limited breeding space, steel geese and Zhexi White Geese are selected as the research objects, and the hybrid advantage groups of steel geese and Zhexi White Geese are fully integrated and tapped. As one of the important indicators for evaluating poultry meat quality, the determination of the drip loss of the muscle of the hybrid geese can measure the breeding efficiency, processing cost and market value.

[0003] The existing method for determining drip loss is to weigh the treated meat sample to obtain the initial weight, hang it on a tripod with a wire, cover it with a plastic wrap to isolate the air, put the tripod into a refrigerator, and store it at 4℃ for 24 hours. After taking it out and weighing it, the final weight is obtained, and the drip loss is calculated based on the final weight and the initial weight. The existing method for determining drip loss can only obtain the terminal value of the drip loss, and cannot obtain the continuous values during the drip loss process, which cannot provide reliable data support for the research and development of hybrid geese.

[0004] The chest muscle and the leg muscle are the main muscle sources of poultry, and the drip loss of the chest muscle and the leg muscle of different varieties of poultry is different. For example, the drip loss of the leg muscle of Wanxi White Goose is significantly lower than that of the chest muscle, while the drip loss of the leg muscle and the chest muscle of Sanhua Goose and Taizhou Goose is not significantly different. In order to avoid the mutual influence between the leg muscle and the chest muscle, the leg muscle and the chest muscle are usually placed in different closed spaces for determination, and the differences in gas content, humidity and temperature of different closed spaces affect the authenticity of the comparison of the drip loss of the leg muscle and the chest muscle. Therefore, it is required to determine the drip loss of the leg muscle and the chest muscle of poultry in the same closed space for comparison, so as to reduce the error caused by environmental factors.

[0005] Therefore, how to continuously determine the chest muscle sample and the leg muscle sample in the same closed space is a problem to be solved in the technical field. SUMMARY

[0044] Embodiment 1

[0045] As shown in Figures 1-2 , the present embodiment provides a meat sample drip loss continuous determination device, comprising:

[0046] a refrigerated cabinet 1, a weight monitoring mechanism 2, a meat sample positioning mechanism 3, and an adsorption mechanism 4;

[0047] The refrigerated cabinet 1 is provided with a plurality of refrigerated cavities 11, and the refrigerated cavities 11 are sealingly connected with a closing door 5. The rear end of the closing door 5 is connected with a bearing frame 51, and the bearing frame 51 is slidingly connected in the refrigerated cavity 11;

[0048] The upper part of the bearing frame 51 is provided with two weight monitoring mechanisms 2, and the front end of the closing door 5 is connected with a shell 52. The shell 52 is provided with a digital display controller 6, and the digital display controller 6 is connected with the weight monitoring mechanism 2 and the adsorption mechanism 4;

[0049] The weight monitoring mechanism 2 is respectively connected with the meat sample positioning mechanism 3, and the meat sample positioning mechanism 3 is used to connect the pectoral muscle sample or the leg muscle sample in a set posture at a specified height in the bearing frame 51;

[0050] The adsorption mechanism 4 is arranged below the bearing frame 51, and the adsorption mechanism 4 is arranged corresponding to the two meat sample positioning mechanisms 3. The adsorption mechanism 4 is used to synchronously adsorb the free water on the surface of the pectoral muscle sample and the leg muscle sample.

[0051] It can be understood that when the drip loss determination is carried out, after the poultry is slaughtered, the same side breast muscle and leg muscle are selected, the regular meat samples are made which are matched with the adsorption mechanism 4, the breast muscle meat sample and the leg muscle meat sample of the poultry are obtained; the monitoring value of the weight monitoring mechanism 2 is zeroed by the digital display controller 6, then the breast muscle meat sample and the leg muscle meat sample of the same poultry are connected on the two meat sample positioning mechanisms 3 on the same bearing frame 51, so that the breast muscle meat sample or the leg muscle meat sample of the poultry is connected in the specified height in the bearing frame 51 in the set posture; the distilled water is sprayed in the adsorption mechanism 4, so that the water film for contacting the surface of the breast muscle meat sample or the leg muscle meat sample is formed in the adsorption mechanism 4, the bearing frame 51 slides into the refrigeration cavity 11, the closed door 5 is sealingly connected with the refrigeration cavity 11 to form a closed space, the temperature of the refrigeration cabinet 1 is set to 4℃, so that the breast muscle meat sample and the leg muscle meat sample of the same poultry are located in the same closed space, and the comparison error caused by the environmental factors is reduced. Then the digital display controller 6 is started to enter the determination state, the adsorption mechanism 4 repeatedly absorbs the free water on the surfaces of the breast muscle meat sample and the leg muscle meat sample on the two meat sample positioning mechanisms 3 at the set adsorption frequency and adsorption time interval.

[0052] When the adsorption mechanism 4 enters the adsorption state, the water film formed by the distilled water directly contacts the surface of the breast muscle meat sample or the leg muscle meat sample, so as to avoid causing friction and extrusion to the breast muscle meat sample or the leg muscle meat sample, and affecting the authenticity of the determination result, and the water film is fused with the free water on the surface of the breast muscle meat sample or the leg muscle meat sample, the overflowed water is adsorbed into the adsorption mechanism 4 for storage, when the adsorption mechanism 4 is separated from the adsorption state, the monitoring values of the two weight monitoring mechanisms 2 on the breast muscle meat sample and the leg muscle meat sample are updated, the weight values of the breast muscle meat sample and the leg muscle meat sample at the time point are acquired by the digital display controller 6, and the drip loss data at the time point is obtained by the digital display controller 6 based on the initial weight; during the determination time, the adsorption mechanism 4 repeatedly switches between the adsorption state and the separation state at the set adsorption frequency and adsorption time interval, and the drip loss data at multiple time points of the breast muscle meat sample and the leg muscle meat sample are continuously and synchronously obtained, and the free water on the surface of the breast muscle meat sample and the leg muscle meat sample is adsorbed in time, so as to avoid the mutual influence of the breast muscle meat sample and the leg muscle meat sample in the same closed space. After the determination time ends, the final drip loss data and the historical drip loss data of the breast muscle meat sample and the leg muscle meat sample are acquired by the digital display controller 6; the breast muscle meat sample and the leg muscle meat sample are removed, the meat sample positioning mechanism 3 is cleaned, and the adsorption mechanism 4 is replaced, and is used again.

[0053] In the technical scheme, the breast muscle sample and the leg muscle sample of the poultry are located in the same closed space, the contrast error caused by the environmental factors is reduced, the water film formed by spraying distilled water in the adsorption mechanism 4 is in direct contact with the surface of the breast muscle sample or the leg muscle sample, the breast muscle sample or the leg muscle sample is prevented from being rubbed and pressed, the adsorption mechanism 4 switches between the adsorption state and the non-adsorption state repeatedly according to the set adsorption frequency and adsorption time, the drip loss data of the breast muscle sample and the leg muscle sample at multiple time points are obtained continuously and synchronously, the free water on the surface of the breast muscle sample and the leg muscle sample is adsorbed in time, the breast muscle sample and the leg muscle sample are prevented from affecting each other in the same closed space, and the breast muscle sample and the leg muscle sample are continuously measured in the same closed space.

[0054] As shown in Figures 2-3 The weight monitoring mechanism 2 includes a heat preservation box body, a heat preservation channel 23 and a weighing sensor 24. The heat preservation box body is connected in the bearing frame 51. One end of the heat preservation channel 23 is in communication with the heat preservation box body, and the other end of the heat preservation channel 23 is provided through the closed door 5. One end of the weighing sensor 24 is connected in the heat preservation box body, and the other end of the weighing sensor 24 is connected with a docking rod 25. The bottom end of the heat preservation box body is provided with a docking channel 26 through which the docking rod 25 is arranged. The meat sample positioning mechanism 3 is connected with the docking rod 25.

[0055] It can be understood that the weighing sensor 24 is connected in the heat preservation box body, so that the low-temperature environment in the refrigeration cavity 11 does not affect the measurement accuracy of the weighing sensor 24. The heat preservation channel 23 is used for protecting the cable of the weighing sensor 24, so that the low-temperature environment in the refrigeration cavity 11 does not affect the measurement accuracy of the weighing sensor 24. The weight of the weighing sensor 24 connected with the docking rod 25 and the meat sample positioning mechanism 3 is zeroed by the digital display controller 6, and then the breast muscle sample and the leg muscle sample of the same poultry are connected to the two meat sample positioning mechanisms 3 on the same bearing frame 51, and the initial weights of the breast muscle sample and the leg muscle sample are measured by the two weighing sensors 24.

[0056] It should be noted that the weighing sensor 24 has a temperature compensation function.

[0057] As shown in Figure 3 The heat preservation box body includes an upper heat preservation barrel 21 and a lower heat preservation barrel 22. The upper heat preservation barrel 21 is connected in the bearing frame 51. The heat preservation channel 23 is in communication with the upper heat preservation barrel 21. The docking channel 26 is provided through the lower heat preservation barrel 22. The lower heat preservation barrel 22 is threadedly connected with the upper heat preservation barrel 21.

[0058] It can be understood that by setting the heat preservation box body as a detachable connection structure of the upper heat preservation barrel body 21 and the lower heat preservation barrel body 22, it is convenient to install or overhaul during installation and adjustment. At the same time, after the upper heat preservation barrel body 21 and the lower heat preservation barrel body 22 are threadedly connected, a closed heat preservation structure of the symmetrical load sensor 24 is formed, which effectively avoids the influence of the low-temperature environment in the refrigeration cavity 11 on the measurement accuracy of the symmetrical load sensor 24.

[0059] As shown in Figure 4 , the rubber cylinder 27 is connected in the docking channel 26, a plurality of rubber ring pieces 28 are arranged in the rubber cylinder 27, the inner side of the rubber ring piece 28 is close to the docking rod 25, the docking rod 25 is a plastic docking rod, a plurality of ring plates 29 are integrally arranged on the plastic docking rod, the outer side of the ring plate 29 is close to the inner wall of the rubber cylinder 27, the plurality of ring plates 29 and the plurality of rubber ring pieces 28 are staggered, and a gap is arranged between the ring plate 29 and the rubber ring piece 28.

[0060] It can be understood that there is a gap between the docking rod 25 and the docking channel 26, and the cold air in the refrigeration cavity 11 will enter the heat preservation box body from the gap between the docking channel 26 and the docking rod 25, which will cause the temperature in the heat preservation box body to gradually decrease, thereby affecting the measurement accuracy of the symmetrical load sensor 24. Therefore, the docking rod 25 is arranged as a plastic docking rod, the heat conduction performance of the plastic docking rod is reduced, the temperature decrease in the heat preservation box body caused by the heat conduction of the docking rod 25 is avoided, a plurality of rubber ring pieces 28 arranged in the rubber cylinder 27 cooperate with a plurality of ring plates 29 arranged on the plastic docking rod to form a plurality of labyrinth structures in the docking channel 26, the cold air in the refrigeration cavity 11 is blocked from entering the heat preservation box body through the gap between the docking channel 26 and the docking rod 25, and the ring plate 29 and the rubber ring piece 28 do not directly contact each other, thereby ensuring the measurement accuracy of the load sensor 24.

[0061] As shown in Figure 2 and Figure 5 , the meat sample positioning mechanism 3 includes a positioning rod 31, two puncture pieces 32 and a positioning needle 33, the positioning rod 31 is connected with the weight monitoring mechanism 2, the two puncture pieces 32 are connected at the bottom end of the positioning rod 31, the puncture piece 32 is provided with a positioning hole, the positioning needle 33 is arranged in the positioning hole, the puncture piece 32 is used for longitudinally puncturing the chest muscle sample or the leg muscle sample, and the positioning needle 33 is used for transversely puncturing the chest muscle sample or the leg muscle sample and then arranged in the positioning hole.

[0062] It can be understood that when the pectoral muscle or leg muscle is connected, the two piercing pieces 32 are longitudinally pierced into the pectoral muscle or leg muscle after adjusting the orientation of the pectoral muscle or leg muscle, the depth of the two piercing pieces 32 is adjusted, the positioning needle 33 is transversely pierced into the pectoral muscle or leg muscle, and the positioning needle 33 is respectively pierced into the positioning hole of the two piercing pieces 32. After the positioning needle 33 is connected with the two piercing pieces 32, the pectoral muscle or leg muscle is fixed and limited in position, so that the free water on the surface of the pectoral muscle and leg muscle is adsorbed by the adsorption mechanism 4.

[0063] As shown in Figure 5 The meat sample positioning mechanism 3 further comprises a first limiting cover 34 and a second limiting cover 35, the first limiting cover 34 is provided with a first positioning arc plate 36 penetratingly, the second limiting cover 35 is provided with a second positioning arc plate 37 penetratingly, the first limiting cover 34 is provided with a plurality of positioning pins 38, the second limiting cover 35 is provided with a plurality of pin holes 39, the positioning pins 38 are gap-fitted in the pin holes 39, the first positioning arc plate 36 is provided with a positioning rod 310, the positioning rod 31 is provided with a positioning groove 311, the positioning rod 310 is slidingly connected in the positioning groove 311, the first limiting cover 34 is provided with a first arc plate 312 penetratingly, the second limiting cover 35 is provided with a second arc plate 313 penetratingly, and the first arc plate 312 abuts against the second arc plate 313 to guide the positioning needle 33 to transversely pierce the pectoral muscle or leg muscle.

[0064] It can be understood that when the puncture piece 32 is longitudinally punctured into the breast muscle or the leg muscle, the puncture piece 32 needs to be punctured from the specified point of the top end of the muscle, and after the breast muscle or the leg muscle punctures the puncture piece 32, it needs to stay at the specified height position on the puncture piece 32, and the positioning needle 33 can be accurately punctured into the positioning hole from the specified point of the side end of the muscle; therefore, the first limiting cover 34 and the second limiting cover 35 are arranged, and when the breast muscle or the leg muscle is connected, the muscle is placed in the first limiting cover 34, and after the cooperation of the plurality of positioning pins 38 and the plurality of pin holes 39, the first limiting cover 34 and the second limiting cover 35 are connected to form a limiting shell, and the muscle gap is limited in the limiting shell; at this time, the first positioning arc plate 36 and the second positioning arc plate 37 cooperate to form a positioning cylinder, and then the limiting shell is rotated, so that the positioning strip 310 in the first positioning arc plate 36 corresponds to the positioning groove 311 on the positioning rod 31, so that the puncture piece 32 can be punctured from the specified point of the top end of the muscle, and after the positioning strip 310 slides from bottom to top in the positioning groove 311 and abuts, the muscle stays at the specified height position on the puncture piece 32, and then the positioning needle 33 is punctured into the muscle under the cooperation of the first arc plate 312 and the second arc plate 313, so that the positioning needle 33 can be accurately punctured into the positioning hole, and then the first limiting cover 34 and the second limiting cover 35 are detached from the two sides of the muscle. In this way, the breast muscle and the leg muscle of the poultry can be limited and connected in the specified height of the bearing frame 51 in the set posture, so as to facilitate the synchronous adsorption of the free water on the surface of the breast muscle and the leg muscle by the adsorption mechanism 4.

[0065] As shown in Figure 6 , the adsorption mechanism 4 includes a heat shield 41, a reciprocating drive assembly 42 and two adsorption assemblies 43, the heat shield 41 is connected in the bearing frame 51, the heat shield 41 is connected through the closed door 5, a plurality of heat dissipation holes are provided on the shell 52, the heat dissipation holes correspond to the heat shield 41, the reciprocating drive assembly 42 is provided through the heat shield 41, the two adsorption assemblies 43 are drivingly connected with the reciprocating drive assembly 42, and the two adsorption assemblies 43 are used for synchronously adsorbing the free water on the surface of the breast muscle and the leg muscle.

[0066] It can be understood that the reciprocating driving assembly 42 reciprocates in the heat shield 41, and the two adsorption assemblies 43 are driven by the reciprocating driving assembly 42 to reciprocate in the refrigeration cavity 11. In the process of reciprocating in the refrigeration cavity 11, the two adsorption assemblies 43 synchronously adsorb free water on the surface of the breast muscle sample and the leg muscle sample. The frequency of the reciprocating movement of the reciprocating driving assembly 42 can be adjusted by the digital controller 6, and the adsorption time of the two adsorption assemblies 43 to the free water on the surface of the breast muscle sample and the leg muscle sample during the reciprocating movement can be adjusted. The friction heat of the reciprocating driving assembly 42 and the particles generated by abrasion can be isolated by the heat shield 41, so as to avoid affecting the temperature in the refrigeration cavity 11 and avoid contaminating the breast muscle sample and the leg muscle sample.

[0067] As shown in Figures 7-8 The adsorption assembly 43 includes two adsorption covers 431, which are detachably connected with the reciprocating driving assembly 42. The adsorption cover 431 is provided with a plurality of openings 432 for avoiding contact with the meat sample positioning mechanism 3. The two adsorption covers 431 are driven to close by the reciprocating driving assembly 42, and are close to the surface of the breast muscle sample or the leg muscle sample. The adsorption cover 431 is provided with an adsorption chamber 433, and the adsorption chamber 433 is provided with adsorption cotton 434. The inner wall of the adsorption cover 431 is coated with a hydrophilic coating, which is used to adsorb water to form a water film. The inner wall of the adsorption cover 431 is provided with a plurality of capillary holes 435 through the adsorption chamber 433.

[0068] It can be understood that when the water loss is determined, distilled water is sprayed in the adsorption cover 431. The distilled water forms a water film on the hydrophilic coating of the inner wall of the adsorption cover 431, which contacts the surface of the breast muscle sample or the leg muscle sample. The distilled water can avoid contaminating the meat sample. When the two adsorption covers 431 are closed by the reciprocating driving assembly 42, the puncture piece 32 and the positioning needle 33 are located in the opening 432 and do not contact the adsorption cover 431. The water film formed on the hydrophilic coating contacts and fuses with the free water on the surface of the breast muscle sample or the leg muscle sample, avoiding friction and extrusion of the breast muscle sample or the leg muscle sample. The water greater than the capacity of the hydrophilic coating is adsorbed into the adsorption chamber 433 through the capillary hole 435. The adsorption cotton 434 further adsorbs the water in the adsorption chamber 433, avoiding backflow of the water in the adsorption chamber 433. After the two adsorption covers 431 are closed for a certain period of time, the reciprocating driving assembly 42 drives the two adsorption covers 431 away from the breast muscle sample or the leg muscle sample. The digital controller 6 acquires the weight value of the breast muscle sample or the leg muscle sample at this time point. Based on the initial weight, the digital controller 6 obtains the water loss data at this time point. The reciprocating driving assembly 42 drives the two adsorption covers 431 of the two adsorption assemblies 43 to reciprocate in the determination time, so as to continuously determine the water loss of the breast muscle sample and the leg muscle sample.

[0069] AsFigure 9 As shown, the reciprocating driving assembly 42 comprises a servo motor 421, two driving plates 422 and four bearing seats 423, the servo motor 421 is arranged in the heat shield 41, the servo motor 421 is connected with the digital controller 6, the servo motor 421 is connected with a T-shaped speed reducer 424, two lead screws 425 are rotatably connected in the heat shield 41, the lead screws 425 are in transmission connection with the T-shaped speed reducer 424, a plurality of light rods 426 are arranged in the heat shield 41, the driving plates 422 are slidably connected on the light rods 426, the lead screws 425 are in threaded connection with the driving plates 422, four strip-shaped holes are formed through the heat shield 41, the bearing seats 423 are slidably connected on the heat shield 41, butt plates 427 are arranged at the bottom ends of the bearing seats 423, the butt plates 427 are connected with the driving plates 422 after penetrating through the strip-shaped holes, the adsorption covers 431 are detachably connected on the bearing seats 423, and the organ cases 428 are arranged between the strip-shaped holes and the bearing seats 423.

[0070] It can be understood that, in the process of continuously determining the synchronous drop water loss of the chest muscle samples and the leg muscle samples, when the servo motor 421 drives the T-shaped speed reducer 424 to rotate clockwise, the two lead screws 425 drive the two driving plates 422 to move close to the middle position, after the two driving plates 422 slide along the light rods 426 to move close to each other, the four bearing seats 423 drive the corresponding two adsorption covers 431 to close, after the servo motor 421 drives the T-shaped speed reducer 424 to rotate clockwise to the position, the servo motor 421 stops for a set time length, so that the adsorption covers 431 adsorb the free water on the surface of the muscle samples for a set time length, after the set time length ends, the servo motor 421 drives the T-shaped speed reducer 424 to rotate counterclockwise, the two lead screws 425 drive the two driving plates 422 to move away from the middle position, after the two driving plates 422 slide along the light rods 426 to move away from each other, the four bearing seats 423 drive the corresponding two adsorption covers 431 to move away from the muscle samples, the digital controller 6 collects the weight value of the chest muscle sample or the leg muscle sample at this time point, and the digital controller 6 obtains the drop water loss data at this time point based on the initial weight. The organ cases 428 seal and dampen during the movement of the bearing seats 423, so that the strip-shaped holes always maintain a sealed state, and the stability of the movement of the adsorption covers 431 is ensured. After the servo motor 421 drives the T-shaped speed reducer 424 to rotate counterclockwise to the position, the servo motor 421 stops for a set interval time length, and after the set interval time length ends, the servo motor 421 drives the T-shaped speed reducer 424 to rotate clockwise again, so as to reciprocate and continuously determine the synchronous drop water loss of the chest muscle samples and the leg muscle samples.
