By setting the grinding machine 3 to drive the rotating rod 41 to rotate at different speeds, the output end of the grinding machine 3 is fixedly connected to the rotating rod 41 through a coupling. A separation mechanism 5 is arranged on the base 2, and an adjustment mechanism 6 is arranged on the base 2. The separation mechanism 5 includes a sealing cover 51. By setting the sealing cover 51, it can prevent the phenomenon that the food to be detected splashes to the outside during grinding. The sealing cover 51 is movably sleeved on the rotating rod 41. A liquid collecting tank 52 is clamped on the outer wall of the top of the base 2. By setting the liquid collecting tank 52, it can collect the liquid materials after grinding. A chute 53 is opened on the outer wall of the top of the liquid collecting tank 52. The inner walls of both sides of the chute 53 are slidably connected with a movable plate 55. The outer wall of the side of the movable plate 55 close to the liquid collecting tank 52 is fixedly connected with a grinding box 56. By setting the grinding box 56, it can collect the solid materials of the food to be detected. A filter hole 57 is opened on the inner wall of the bottom of the grinding box 56. By setting the filter hole 57, it can carry out solid-liquid separation on the food to be detected.

[0025] Referring to Figures 2 - 3 , the sealing cover 51 is clamped on the outer wall of the bottom of the grinding machine 3. The inner diameter of the liquid collecting tank 52 is adapted to the outer diameter of the sealing cover 51. An indication mark is opened on the outer wall of the top of the movable plate 55. By setting the indication mark, it can prompt the operation method. The end of the rotating rod 41 far from the grinding machine 3 is fixedly connected with a grinding disc 42. By setting the grinding disc 42, it can grind the pretreated food. The outer diameter of the grinding disc 42 is adapted to the inner diameter of the grinding box 56.

[0026] Referring to Figures 3 - 4 , the adjustment mechanism 6 includes a limit opening 61. The limit opening 61 is opened on the outer wall of the front side of the liquid collecting tank 52. An installation groove 62 is opened on the outer wall of the top of the base 2. A triangular block 63 is slidably connected to the inner wall of the top of the base 2. By setting the triangular block 63, it can be clamped and fixed to and separated from the limit opening 61. A telescopic spring 64 is fixedly connected to the outer wall of the rear side of the triangular block 63. By setting the telescopic spring 64, it can continuously push the triangular block 63. A dial 65 is fixedly connected to the outer wall of the top of the triangular block 63. By setting the dial 65, it is convenient for personnel to operate and use. The triangular block 63 is clamped on the inner wall of one side of the limit opening 61. A wear-resistant pad is fixedly connected to the outer wall of the side of the triangular block 63. By setting the wear-resistant pad, it can reduce the wear of the triangular block 63 in the limit opening 61. The end of the telescopic spring 64 far from the triangular block 63 is fixedly connected to the inner wall of one side of the base 2. A frosted pad is fixedly connected to the outer wall of the side of the dial 65. By setting the frosted pad, it can reduce the slipping phenomenon when personnel use the dial 65.

[0027] Working principle: Put the food to be detected into the grinding box 56. Then, place the grinding box 56 into the chute 53 through the movable plate 55. Subsequently, lower the grinding machine 3 to the sealing cover 51 so that it is slidably connected to the inner wall of the liquid accumulation tank 52. Turn on the grinding machine 3 to make the rotating rod 41 rotate. The rotation of the rotating rod 41 drives the grinding disc 42 to rotate, grinding the food to be detected. During the grinding process, the liquid material flows into the liquid accumulation tank 52 through the filter holes 57 for solid-liquid separation. When cleaning and maintenance are required, pull the paddle 65 to move the triangular block 63. The movement of the triangular block 63 compresses the telescopic spring 64. At the same time, the triangular block 63 moves out of the limiting port 61. Then, disassemble the liquid accumulation tank 52 to perform internal cleaning, take it out for rinsing, and for convenient installation.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
