DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] See also Figure 1-3 The meat freshness detection device includes a detection table 1 for placing a detection test paper to detect data such as meat freshness, pH value, and moisture content. A bracket 2 is fixedly connected to the upper surface of the detection table 1.

[0030] A mincing device for crushing meat products is installed in the inner cavity of the bracket 2. Large pieces of meat are minced by the mincing device to facilitate the subsequent extraction of tissue fluid in the meat for testing.

[0031] An extrusion device for conveying minced meat is installed below the mincing device, and collecting devices for collecting tissue fluid in the minced meat for testing are installed on both sides of the bottom of the extrusion device. When the minced meat enters the extrusion device, the minced meat can be squeezed by the extrusion device to squeeze out the tissue fluid in the minced meat and introduce it into the collecting device for collection.

[0032] The mincing device includes a wall-breaking cylinder 3 fixedly connected to the top wall of the inner cavity of the bracket 2, a transmission shaft 5 is embedded in the inner cavity of the wall-breaking cylinder 3, the top end of the transmission shaft 5 passes through the bracket 2 and is rotatably connected to the bracket 2, a motor 4 is installed on the top of the bracket 2, and the output end of the motor 4 is fixedly connected to the top end of the transmission shaft 5. A baffle 7 is fixedly connected to the middle section of the transmission shaft 5, and a blade 8 is fixedly connected to the transmission shaft 5 above the baffle 7. After the meat is introduced into the wall-breaking cylinder 3, the large pieces of meat are supported by the baffle 7 and stay in the wall-breaking cylinder 3. At this time, the user can start the motor 4, drive the transmission shaft 5 to rotate through the motor 4, and drive the blade 8 to rotate at high speed to chop the large pieces of meat.

[0033] The extrusion device includes a transmission tube 9 fixedly connected to the bottom of the wall-breaking cylinder 3 and connected to the inner cavity of the wall-breaking cylinder 3. An auger 10 is rotatably connected in the inner cavity of the transmission tube 9. The end of the transmission shaft 5 away from the motor 4 is fixedly connected to the top of the auger 10. A discharge nozzle 11 is fixedly connected to the bottom end of the transmission tube 9. A first valve 12 is installed at the open end of the discharge nozzle 11. The collection device is installed on the side wall of the discharge nozzle 11. When the minced meat falls into the transmission tube 9 under the action of gravity, the rotation of the transmission shaft 5 can drive the auger 10 to rotate synchronously and transport the minced meat downward along the transmission tube 9. At this time, the user closes the first valve 12 and squeezes the minced meat in the inner cavity of the discharge nozzle 11, so that the tissue fluid in the minced meat flows into the collection device, which is convenient for subsequent detection of the tissue fluid.

[0034] Reference Figure 1 The connection between the transmission shaft 5 and the bracket 2 is sleeved with a bearing 6, the inner ring of the bearing 6 is fixedly connected to the transmission shaft 5, and the outer ring of the bearing 6 is embedded in the bracket 2 and fixedly connected to the bracket 2. The bearing 6 is installed at the connection between the transmission shaft 5 and the bracket 2 to reduce the resistance of the transmission shaft 5 when rotating, so that the motor 4 can drive the transmission shaft 5 to rotate.

[0035] Reference Figure 1 The baffle 7 is in a funnel-shaped structure, and a gap is left between the bottom periphery of the baffle 7 and the inner wall of the wall-breaking cylinder 3 for the minced meat to pass through. The baffle 7 is used to block large pieces of meat, so that the large pieces of meat stay inside the wall-breaking cylinder 3, which is convenient for mincing the meat. A gap is left between the bottom periphery of the baffle 7 and the inner wall of the wall-breaking cylinder 3 for the minced meat to pass through, so that the minced meat can fall into the inner cavity of the transmission tube 9 below through the gap.

[0036] Reference Figure 2The transmission tube 9 is a circular tube structure, and the inner wall of the transmission tube 9 is in sliding contact with the circumference of the auger 10. The auger 10 can cooperate with the side wall of the transmission tube 9 to transmit the minced meat downward during the rotation process, and the minced meat at the top moves and squeezes the minced meat at the bottom, so as to squeeze out the tissue fluid in the minced meat.

[0037] Reference Figure 3 The collecting device includes two collecting barrels 15 arranged on both sides of the discharge nozzle 11. The two collecting barrels 15 are fixedly connected to an inclined drainage pipe 13 on one side close to the discharge nozzle 11. The end of the drainage pipe 13 away from the collecting barrel 15 passes through the discharge nozzle 11 and is connected to the inner cavity of the discharge nozzle 11. A filter 14 for filtering minced meat is fixedly connected to the inner cavity of the end of the drainage pipe 13 connected to the discharge nozzle 11. When the first valve 12 is closed, the minced meat accumulated in the inner cavity of the discharge nozzle 11 is squeezed by the minced meat inside the transmission tube 9, so that the tissue fluid in the minced meat is filtered by the filter 14 and then introduced into the inner cavity of the collecting barrel 15 along the drainage pipe 13 and collected.

[0038] Reference Figure 2 The bottom ends of the two collecting barrels 15 are fixedly connected with sampling tubes 16, which are connected to the inner cavity of the collecting barrels 15. A second valve 17 is installed at the connection between the sampling tube 16 and the collecting barrel 15. When the user needs to test the tissue fluid, he can select a suitable test paper and place it on the testing table 1 below the sampling tube 16, then open the second valve 17, and drop the tissue fluid in the inner cavity of the collecting barrel 15 onto the test paper, so that the meat product can be tested.

[0039] Reference Figure 3 A fixing ring 18 is fixedly connected to one end of the transmission tube 9 away from the wall-breaking cylinder 3, and a reinforcing rod 19 is provided between the outer wall of the fixing ring 18 and the inner wall of the bracket 2. The fixing ring 18 is fixedly connected to the inner wall of the bracket 2 through the reinforcing rod 19. The fixing ring 18 and the reinforcing rod 19 are provided to fix the bottom end of the transmission tube 9, thereby improving the stability of the installation of the transmission tube 9.

[0040] The implementation principle of the present application is as follows: when in use, the user first puts a large piece of meat into the wall-breaking cylinder 3, and then starts the motor 4 to drive the blade 8 installed on the transmission shaft 5 to rotate at high speed to mince the large piece of meat. The minced meat falls into the transmission pipe 9 through the gap between the baffle 7 and the inner wall of the wall-breaking cylinder 3. The auger 10 rotates synchronously under the drive of the transmission shaft 5 and transports the minced meat along the transmission pipe 9 to the discharge nozzle 11. At this time, the user closes the first valve 12, and the minced meat accumulated in the inner cavity of the discharge nozzle 11 is squeezed by the minced meat inside the transmission pipe 9. The tissue fluid in the minced meat is filtered through the filter screen 14 and then introduced into the inner cavity of the collection barrel 15 along the drainage pipe 13 for collection. When the user needs to test the tissue fluid, a suitable test paper can be selected and placed on the test table 1 under the sampling tube 16, and then the second valve 17 is opened to drop the tissue fluid in the inner cavity of the collection barrel 15 onto the test paper, so that the meat product can be tested, and the existing testing equipment is avoided as much as possible to squeeze and crush the meat by manual pressing, which is not only inefficient but also time-consuming and labor-intensive.
