With the rapid development of the national economy, people's income, especially urban residents', has continued to increase, food consumption has increased significantly, and material wealth has increased, but there is a serious problem of unreasonable dietary structure, that is, nutritional imbalance.

[0043] Embodiment three:

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a grinding assembly 8 is provided inside the processing box 3, and the grinding assembly 8 includes a fourth motor 801 fixedly installed on the side surface of the processing box 3 through a bracket, a rotating plate 802 is fixedly installed on the output end of the fourth motor 801 through a driving shaft, a driven rod 803 is fixedly installed on one side surface of the rotating plate 802, a reciprocating frame 804 is slidably connected to the outer surface of the driven rod 803, a second guide column 805 is slidably penetrated and connected to the top of the reciprocating frame 804, and side plates are fixedly installed at both ends of the second guide column 805, a telescopic card plate 806 is provided inside the processing box 3, a first spring is provided inside the telescopic card plate 806, a support column is fixedly installed on the bottom of the telescopic card plate 806, and the outer surface of the support column is rotatably connected to Grinding roller 807, an arc plate 808 is arranged inside the processing box 3, screening holes are opened on the surface of the arc plate 808, support members are slidably connected at the four corners of the surface of the arc plate 808, the support members are fixedly installed on the inner wall of the processing box 3, a second spring 809 is arranged on the surface of the support member and the arc plate 808, a cross column is slidably penetrated and connected on the surface of the telescopic clamping plate 806, the cross column is fixedly installed on the inner wall of the processing box 3, side baffles are fixedly installed on both sides of the upper surface of the arc plate 808, cams 810 are overlapped on both sides of the lower surface of the arc plate 808, a driven shaft is fixedly installed inside the cam 810, a first pulley is fixedly installed on the outer surface of the driven shaft and the driving shaft, and belts are overlapped on the outer surfaces of the two first pulleys.

[0045] In this embodiment: an equal amount of food samples falls onto the surface of the arc plate 808, and then needs to be ground and crushed. The staff starts the fourth motor 801 to drive the rotating plate 802 to rotate, and the rotating plate 802 drives the driven rod 803 to rotate. The movable driven rod 803 slides inside the reciprocating frame 804 and makes the reciprocating frame 804 slide back and forth. The reciprocating frame 804 drives the telescopic card plate 806 to move synchronously. The telescopic card plate 806 drives the grinding roller 807 at the bottom to slide back and forth on the surface of the arc plate 808 and grind the food above. The ground food falls downward through the screening hole. The telescopic card plate 806 drives the grinding roller 807 at the bottom to move, causing the telescopic card plate 806 to deform and squeeze the first spring inside, so that the grinding roller 807 is always in close contact with the surface of the arc plate 808. When the driving shaft rotates, the driven shaft is driven to rotate through the first pulley, and the driven shaft drives the cam 810 to rotate. The rotation of the cam 810 drives the arc plate 808 to move up and down. The arc plate 808 causes the second spring 809 to deform during the downward shaking movement. The up and down shaking arc plate 808 drives the food sample on the surface to move, so that the grinding roller 807 can better grind it.

[0048] In this embodiment, after the grinding, the food sample falls into the stirring pool 901, and then a suitable solution is added through the injection tube. Then, during the grinding process, the driven shaft drives the support shaft to rotate through the second pulley 907, and the support shaft drives the reciprocating screw rod 906 to rotate, and the reciprocating screw rod 906 drives the moving frame 905 to move, and the moving frame 905 drives the stirring roller and the stirring blade 902 at the bottom to slide inside the stirring pool 901, and the stirring roller drives the second gears 903 at both ends to move, and the second gears 903 are under the second tooth plate 904. The surface slides, and the meshing connection relationship allows the second gear 903 to rotate during the movement. The rotation of the second gear 903 drives the stirring blade 902 to rotate through the stirring roller, thereby accelerating the fusion of the auxiliary food sample and the solution. After the fusion is completed, the drain pipe is opened by opening the valve. A detection cylinder is placed on the surface of the conveyor belt to carry the food sample to be tested. In this way, the food samples from several parts are sent for inspection in turn, and the internal nutritional components are detected by the near-infrared spectrometer 10, and the nutritional components are displayed on the display 11.
