[0001] This utility model belongs to the field of meat quality testing, specifically a sample hanging bag based on the determination of juice loss in meat quality testing. Background Technology

[0002] Meat juice loss measurement is an important method for assessing the water retention of meat products.

[0003] In existing technologies, the determination of juice loss in meat samples is mostly carried out by manually hanging the meat sample on a hook and then suspending it in the packaging bag. This manual operation is cumbersome, and manual handling can easily cause the meat sample to shake. After hanging, the bag is also easily bumped by external objects, which can cause the meat sample to come into contact with the bag, thus hindering the flow of juice or causing the juice on the bag to be absorbed by the meat sample and flow back, affecting the accuracy of the final measurement. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main objective of this utility model is to provide a sample hanging bag based on the determination of juice loss for meat quality testing.

[0005] The technical solution of this utility model is as follows: a sample hanging bag for measuring juice loss in meat quality testing includes a fixing plate, a bag body is fixedly connected to the bottom of the fixing plate, a limiting rod is fixedly connected to the bottom of the fixing plate and inside the bag body, a hook is slidably connected to the outside of the limiting rod, rotating shafts are rotatably connected to both sides of the inside of the fixing plate, support plates are fixedly connected to the outside of the two rotating shafts extending into the inside of the bag body, an air inlet is provided on one side of the outside of the bag body, a self-sealing opening is provided at the bottom of the bag body, and a transmission component is provided inside the fixing plate.

[0006] In a preferred embodiment, the transmission assembly includes a worm gear and a linkage unit. The worm gear is rotatably connected to the inside of a fixed plate, and a first bevel gear is fixedly connected to the outside of the worm gear. A lead screw is rotatably connected to the inside of the fixed plate extending into the inside of the bag body. A second bevel gear is fixedly connected to the top of the lead screw.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-6 A sample hanging bag for measuring juice loss in meat quality testing includes a fixing plate 1, a bag body 2 fixedly connected to the bottom of the fixing plate 1, a limiting rod 3 fixedly connected to the bottom of the fixing plate 1 and inside the bag body 2, a hook 4 slidably connected to the outside of the limiting rod 3, rotating shafts 7 rotatably connected to both sides inside the fixing plate 1, support plates 5 fixedly connected to the outside of the two rotating shafts 7 extending into the inside of the bag body 2, an inflation port 6 provided on one side of the outside of the bag body 2, a self-sealing opening 16 opened at the bottom of the bag body 2, and a transmission assembly provided inside the fixing plate 1.

[0023] Specifically, the transmission assembly includes a worm gear 8 and a linkage unit. The worm gear 8 is rotatably connected to the inside of the fixed plate 1. A first bevel gear 9 is fixedly connected to the outside of the worm gear 8. A lead screw 10 is rotatably connected to the inside of the fixed plate 1 extending to the inside of the bag body 2. A second bevel gear 11 is fixedly connected to the top of the lead screw 10. The first bevel gear 9 and the second bevel gear 11 are meshed together. A hook 4 is threaded to the outside of the lead screw 10. The support plate 5 can be rotated through the linkage unit. The linkage unit includes a worm wheel 12. The worm wheels 12 are fixedly connected to the outside of the two rotating shafts 7 respectively. The worm gear 8 is meshed with the two worm wheels 12 respectively.

[0024] Using the above technical solution, the bag body 2 is first hung at a designated location using the fixing plate 1 and hook 4. Then, the cut meat sample is hung with hook 4. At this time, the fixing plate 1 is stabilized, and the knob 15 is turned to drive the ratchet 13 and worm 8 to rotate. The pawl 14 slides repeatedly on multiple teeth of the ratchet 13, thus not affecting the rotation of the ratchet 13 and worm 8. During the rotation of the worm 8, the first bevel gear 9 is driven to rotate, and at the same time, the two worm gears 12 and the rotating shaft 7 are driven to rotate through the meshing relationship. The first bevel gear 9 then drives the second bevel gear 11 and the lead screw 10 to rotate through the meshing relationship, so that the lead screw... 10. The hook 4 and meat sample are lifted through the threaded connection until the meat sample is inside the bag 2. At the same time, when the rotating shaft 7 rotates, the corresponding support plate 5 can be rotated and opened outward to support the inner wall of the bag 2. This not only prevents the meat sample from shaking and contacting the inner wall of the bag 2, but also prevents the bag 2 from being hit by external objects and coming into contact with the meat sample, ensuring the meat sample is suspended. This improves the efficiency of juice loss measurement. After the meat sample is suspended, stop rotating the knob 15. The ratchet 14 will lock in place to prevent the ratchet 13 from reversing with the worm gear 8. Turn the bag 2 around, seal the self-sealing opening 16 with the self-sealing strip 17, and then inflate the bag 2 with air through the air inlet 6. After inflation, seal the air inlet 6 with the sealing plug 18, and the meat sample can be hung. After hanging for 24 hours, turn the pawl 14 outward to reverse the worm gear 8, then open the self-sealing opening 16 and lower the hook 4 and meat sample through the reverse process to facilitate the removal of the meat sample. After removing the meat strips, use ordinary absorbent paper or qualitative filter paper to absorb the surface moisture of the meat strips, and weigh them again. The percentage of the weight loss of the meat strips before and after hanging relative to their original weight is the juice loss. Before use, the support plates 5 on both sides of the device are folded up for easy storage and carrying. When it is necessary to hang the meat sample, the hook 4 can be used to lift the meat sample into the bag 2, and at the same time, the two support plates 5 will be flipped open to the sides to support the inner wall of the bag 2. This not only prevents the meat sample inside from shaking and contacting the inner wall of the bag 2, but also prevents the bag 2 from being hit by external objects and coming into contact with the meat sample, ensuring that the meat sample is suspended. This improves the efficiency of juice loss measurement, replaces manual operation, avoids trouble, and ensures the accuracy and efficiency of meat sample detection.

[0025] Specifically, one end of the worm gear 8 extends to the outside of the fixed plate 1 and is fixedly connected to a ratchet 13. A pawl 14 is rotatably connected to the outside of the fixed plate 1 near the ratchet 13. A torsion spring is provided at the rotatable connection between the pawl 14 and the fixed plate 1. A knob 15 is fixedly connected to the outside of the ratchet 13. The knob 15 is knurled on the outside. A self-sealing strip 17 is provided inside the self-sealing opening 16. A sealing plug 18 is provided outside the air inlet 6. A hanging ring 19 is fixedly connected to the top of the fixed plate 1.

[0026] The above technical solution improves the friction between the knob 15 and the operator's hand by setting the knurled texture, thus preventing slippage during operation. The self-sealing strip 17 and sealing plug 18 improve the sealing performance of the device, thus preventing internal gas leakage.

[0027] In use, first, hang the bag 2 at the designated location using the fixing plate 1 and hook 4. Then, hang the cut meat sample on the hook 4. At this time, stabilize the fixing plate 1 and turn the knob 15 to drive the ratchet 13 and worm 8 to rotate. The pawl 14 slides repeatedly on multiple teeth of the ratchet 13, thus not affecting the rotation of the ratchet 13 and worm 8. During the rotation of the worm 8, it drives the first bevel gear 9 to rotate, and at the same time, through the meshing relationship, it drives the two worm gears 12 and the rotating shaft 7 to rotate. The first bevel gear 9 then drives the second bevel gear 11 and the lead screw 10 to rotate through the meshing relationship, so that the lead screw 10 drives the hook 4 and the meat sample to rise through the threaded connection. The rotating shaft 7 causes the meat sample to rise into the interior of the bag 2. Simultaneously, the rotating shaft 7 causes the corresponding support plate 5 to flip and open outwards, supporting the inner wall of the bag 2. This not only prevents the meat sample from shaking and contacting the inner wall of the bag 2, but also prevents the bag 2 from being struck by external objects, ensuring the meat sample remains suspended. This improves the efficiency of juice loss measurement. After the meat sample is suspended, stopping the rotation of knob 15 prevents the ratchet 13 and worm gear 8 from reversing under the locking of pawl 14. The self-sealing strip 17 seals the self-sealing opening 16, and then air is injected into the bag 2 through the inflation port 6. After completion, the air inlet 6 is sealed with the sealing plug 18, and the meat sample can be hung. After hanging for 24 hours, the pawl 14 is rotated outward to reverse the worm gear 8. Then, the self-sealing opening 16 is opened, and the hook 4 and the meat sample are lowered by the reverse process described above, making it easy to remove the meat sample. After removing the meat strips, use ordinary absorbent paper or qualitative filter paper to absorb the surface moisture of the meat strips, and weigh them again. The percentage of the weight loss of the meat strips before and after hanging relative to their original weight is the juice loss. Before use, the support plates 5 on both sides of this device are in the folded state for easy storage and carrying. When it is necessary to hang the meat sample, the hook 4 can be used to lift the meat sample into the bag body 2. Simultaneously, the two support plates 5 are rotated and opened to both sides, supporting the inner wall of the bag 2. This not only prevents the meat sample from shaking and contacting the inner wall of the bag 2, but also prevents the bag 2 from being hit by external objects and coming into contact with the meat sample, ensuring the meat sample remains suspended. This improves the efficiency of juice loss measurement, replaces manual operation, avoids trouble, and ensures the accuracy and efficiency of meat sample detection. The knurled pattern increases the friction between the knob 15 and the operator's hand, preventing slippage during operation. The self-sealing strip 17 and sealing plug 18 improve the sealing performance of the device, preventing internal gas leakage.
