Technical Field

[0001] The present invention relates to the technical field of meat drip loss measurement, and in particular to a method and device for automatically measuring meat drip loss. Background Art

[0002] With the significant improvement of animal genetic improvement technology, the lean meat rate of pork has been greatly improved, the growth rate of pigs has been significantly improved, and the feed conversion rate has also been improved. However, with the increase in lean meat rate, the quality of meat has declined, which is mainly manifested in the whitening of meat color, rapid decrease in pH value, and decreased water retention capacity, causing great economic losses to pig farming. According to research, the problem of pork dripping is quite serious in the high temperature areas in southern my country, with an incidence rate of 10% or even 30%. Therefore, it is necessary to test the dripping rate of pork in order to make corresponding improvements in pig breeding.

[0003] When measuring pork, the sample is first weighed on a scale (m1). The sample is then hung from an S-shaped hook and placed in a plastic bag, ensuring the bag does not touch the sample. The sample is then hung in an environment with constant humidity, airflow, and temperature. After 24 hours, the sample is removed from the hook and weighed again (m2). Drip loss is expressed as the drip loss rate: Drip loss (%) = (m1 - m2) / m1 × 100%.

[0018] A method for automatically measuring drip loss of meat, comprising the following steps:

[0019] S1. Start the motor, which drives the screw to rotate. When the screw rotates, it drives the movable plate, the connecting plate and the cover plate to move upward. When the cover plate moves upward, it drives the hollow shaft, the drain rack and the drain collection device to move upward to the top of the constant temperature box.

[0024] At the same time, through the above technical solutions, the present invention has at least the following beneficial effects:

[0025] 1. The present invention provides a method and device for automatically measuring the drip loss of meat. By moving the cover plate upward, the cover plate can drive the hollow shaft, the drain rack and the drain collection device to move upward to the top of the constant temperature box during the upward movement. Then, the positioning screws are loosened to rotate the drain rack and the installation around the hollow shaft, thereby moving the drain rack, the hanging rod and multiple hooks to the outside, which can flexibly perform meat hanging operations, is not only safer but also more efficient.

[0026] 2. The present invention adds multiple evenly arranged hooks to a constant temperature box to ensure a sufficient number of repetitions. At the same time, it requires that the cut meat comes from the same part. Each row of hooks is equipped with a weight sensor, which can be used to conduct comparative tests on the drip loss of multiple test groups of meat and monitor the weight of the meat hung on them in real time. This solves the problem of manual inability to measure in real time and frequent movement affecting the drip loss data, and realizes automatic and accurate measurement of drip loss data.

[0027] 3. The present invention can realize the function of batch detection by setting a weight sensor and a controller, thereby improving the working efficiency of detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Preferably, a thermostat is provided in the thermostat box 2, and a temperature probe is provided on the cover plate 4. The temperature probe is electrically connected to the thermostat and is used to monitor the temperature inside the thermostat box 2 in real time to ensure that the thermostat box 2 maintains a constant temperature environment. In some embodiments, the thermostat box 2 is a square refrigerator.

[0044] A drain collection device 10 is provided between two adjacent drain racks 6 , and the drain collection device 10 is used to introduce water into the hollow shaft 5 . A controller 11 is installed on the front of the constant temperature box 2 , and the upper and lower adjustment components 3 and the weighing sensor 8 are electrically connected to the controller 11 .

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the four end corners of the bottom of the base plate 1 are fixedly connected to support legs 101, and the bottom ends of the support legs 101 are fixedly connected to anti-slip pads.

[0046] like Figure 2 and Figure 4 As shown, in this embodiment, a drain pipe 201 is provided at the bottom end of one side of the thermostat box 2, and a control valve 202 is installed on the drain pipe 201. The inner bottom wall of the thermostat box 2 gradually slopes toward the drain pipe 201, so that water dripping into the thermostat box 2 can be drained through the drain pipe 201 and the control valve 202, which is very convenient.

[0047] like Figure 1 and Figure 3As shown, in this embodiment, the up and down adjustment component 3 includes a fixed box 301 fixedly connected to one end of the top of the base plate 1, and the inner bottom wall of the fixed box 301 is fixedly connected to a motor 304, and the motor 304 is electrically connected to the controller 11. The output end of the motor 304 is fixedly connected to a screw rod 305, and a movable plate 302 is sleeved on the screw rod 305. The screw rod 305 is threadedly connected to the movable plate 302, and the two ends of the top of the movable plate 302 are fixedly connected to a connecting plate 303. The top end of the connecting plate 303 passes through the fixed box 301 and is fixedly connected to the cover plate 4. The connecting plate 303 is slidably connected to the fixed box 301, and the top end of the screw rod 305 is rotatably connected to the inner top wall of the fixed box 301 through a bearing.

[0048] When hanging meat, start the motor 304 to drive the screw rod 305 to rotate. Since the screw rod 305 is threadedly connected to the movable plate 302, the screw rod 305 can drive the movable plate 302, the connecting plate 303 and the cover plate 4 to move upward during the rotation. The cover plate 4 can drive the hollow shaft 5, the drain rack 6 and the drain collection device 10 to move upward to the top of the constant temperature box 2 during the upward movement, so as to facilitate the hanging of meat.

[0049] like Figure 1 and Figure 6 As shown, in this embodiment, a sealing ring 401 is fixedly connected to the bottom of the cover plate 4, and the cover plate 4 is adapted to the constant temperature box 2. During operation, the sealing ring 401 ensures the sealing between the cover plate 4 and the constant temperature box 2, thereby better maintaining a constant temperature.

[0050] like Figure 4 and Figure 6 As shown, in this embodiment, the number of drain racks 6 is three, and weight-reducing holes 601 are opened on the drain rack 6. A plurality of slide rods 602 are fixedly connected to both sides of the bottom end of the drain rack 6. The bottom end of the slide rod 602 passes through the hanging rod 7 and is fixedly connected to the limit block 603. The slide rod 602 is slidably connected to the hanging rod 7, so that the hanging rod 7 can move up and down along the slide rod 602, and the weight of the multiple suspended meats is measured by a weighing sensor 8.

[0051] like Figure 4 and Figure 6 As shown, in this embodiment, one end of the drain rack 6 is fixedly connected to a mounting ring 604, and the mounting ring 604 is rotatably connected to the outside of the hollow shaft 5. One side of the mounting ring 604 is threadedly connected to a positioning screw 605, and one end of the positioning screw 605 passes through the mounting ring 604 and abuts against the hollow shaft 5, so that the positioning screw 605 can be tightened against the outside of the hollow shaft 5, which can prevent the mounting ring 604 from rotating on the outside of the hollow shaft 5.

[0052] During operation, the drain rack 6 and the mounting ring 604 are rotated around the hollow shaft 5 by loosening the positioning screw 605, thereby moving the drain rack 6, the hanging rod 7 and the plurality of hooks 9 to the outside, so that the meat hanging operation can be performed flexibly.

[0053] like Figure 6 and Figure 7 As shown, in this embodiment, the drainage collection device 10 includes a fixed plate 1001 fixedly connected to the hollow shaft 5, a groove 1002 is provided on the upper surface of the fixed plate 1001, and a drain outlet 1003 connected to the groove 1002 is provided on the hollow shaft 5, and the bottom of the groove 1002 is inclined toward the drain outlet 1003.

[0054] During the drainage test, the moisture of the meat will drip into the groove 1002 on the fixed plate 1001 and then drip along the drain port 1003 and the hollow shaft 5 to the bottom of the constant temperature box 2.

[0055] The method for automatically measuring the drip loss of meat provided by the present invention and the use process of the device thereof are as follows: when hanging meat, the motor 304 is started to drive the screw rod 305 to rotate. Since the screw rod 305 is threadedly connected to the movable plate 302, the screw rod 305 can drive the movable plate 302, the connecting plate 303 and the cover plate 4 to move upward during the rotation. The cover plate 4 can drive the hollow shaft 5, the drain rack 6 and the drain collection device 10 to move upward to the top of the constant temperature box 2 during the upward movement. Then, the positioning screw 605 is loosened to rotate the drain rack 6 and the mounting ring 604 around the hollow shaft 5, thereby moving the drain rack 6, the hanging rod 7 and the multiple hooks 9 to the outside, so that the meat hanging operation can be carried out flexibly, which is not only safe but also more efficient.

[0056] Then, after the meat to be measured is hung on the hook 9, the weighing sensor 8 transmits the initial weight to the controller 11, and then the drain rack 6 and the mounting ring 604 are rotated around the hollow shaft 5 until the drain rack 6, the hanging rod 7 and the multiple hooks 9 are rotated above the constant temperature box 2, and then the positioning screw 605 is loosened to fix the drain rack 6, and then the motor 304 is started to drive the screw rod 305 to reverse. Since the screw rod 305 is threadedly connected to the movable plate 302, the screw rod 305 can drive the movable plate 302, the connecting plate 303 and the cover plate 4 to move downward into the constant temperature box 2 during the rotation process. At this time, the cover plate 4, the sealing ring 401 and the constant temperature box 2 form a constant temperature environment;

[0057] During the drainage test, the moisture of the meat will drip into the groove 1002 on the fixed plate 1001, and then drip to the bottom of the constant temperature box 2 along the drain port 1003 and the hollow shaft 5, so that when a large amount of meat is hung, the moisture dripping from the upper side will not flow to the meat on the lower side. After the test time is up, the weighing sensor 8 on the hanging rod 7 will transmit the final weight to the controller 11. The controller 11 will compare the current weight with the weight during hanging and calculate the drip loss, thereby realizing the function of batch detection and improving the work efficiency of detection.

[0058] Example 2

[0059] A method for automatically measuring drip loss of meat, comprising the following steps:

[0060] S1. Start the motor 304. The motor 304 drives the screw rod 305 to rotate. When the screw rod 305 rotates, it drives the movable plate 302, the connecting plate 303 and the cover plate 4 to move upward. When the cover plate 4 moves upward, it drives the hollow shaft 5, the drain rack 6 and the drain collection device 10 to move upward to the top of the constant temperature box 2. Then, loosen the positioning screw 605 to rotate the drain rack 6 and the mounting ring 604 around the hollow shaft 5, and move the drain rack 6, the hanging rod 7 and the multiple hooks 9 to the outside.

[0061] S2. Hang the meat to be measured on the hook 9. The weighing sensor 8 transmits the initial weight to the controller 11. Then, the drain rack 6 and the mounting ring 604 are rotated around the hollow shaft 5 until the drain rack 6, the hanging rod 7, and the multiple hooks 9 are rotated above the constant temperature box 2. Then, the positioning screws 605 are tightened to fix the drain rack 6. Then, the motor 304 is started. The motor 304 drives the screw rod 305 to reverse. When the screw rod 305 reverses, it drives the movable plate 302, the connecting plate 303, and the cover plate 4 to move downward into the constant temperature box 2.

[0062] S3, the cover plate 4, the sealing ring 401 and the thermostat 2 form a constant temperature environment. During the water drain test, the moisture from the meat will drip into the groove 1002 on the fixed plate 1001, and then drip along the drain port 1003 and the hollow shaft 5 to the bottom of the thermostat 2. This prevents the moisture dripping from the upper side from flowing onto the meat below while hanging a large amount of meat.

[0063] S4. After the test time is up, the weighing sensor 8 on the hanging rod 7 transmits the final weight to the controller 11. The controller 11 compares the current weight with the weight during hanging and calculates the drip loss.

When the screw rod (305) reverses, it drives the movable plate (302), the connecting plate (303) and the cover plate (4) to move downward into the constant temperature box (2); S3, the cover plate (4), the sealing ring (401) and the thermostat (2) form a constant temperature environment. During the water drain test, the moisture of the meat will drip into the groove (1002) on the fixed plate (1001), and then drip along the drain port (1003) and the hollow shaft (5) to the bottom of the thermostat (2). Thus, when a large amount of meat is hung, the moisture dripping from the upper side will not flow to the meat on the lower side. S4. After the test time is up, the weighing sensor (8) on the hanging rod (7) transmits the final weight to the controller (11). The controller (11) compares the current weight with the weight during the hanging process and calculates the drip loss.
