At the same time, a set of one-way pressure valves 28 are provided in the dairy product input pipe 21 and the waste liquid discharge pipe 22. The one-way pressure valve 28 opens when it is subjected to pressure and controls the one-way flow of liquid inside the dairy product input pipe 21 and the waste liquid discharge pipe 22. That is, when the dairy product input pipe 21 is subjected to the pressure of the dairy product injected from the dairy product feed port 14, it opens to input the dairy product into the dairy product moisture detection chamber 19. When the one-way pressure valve 28 in the waste liquid discharge pipe 22 is subjected to outward pressure, it opens to discharge the waste liquid inside the dairy product moisture detection chamber 19.

[0023] As a preferred embodiment of the present invention, see Figure 2 、 Figure 4 The detection component includes a detection slot provided inside the side wall of the dairy product moisture detection chamber 19, and a group of moisture detection probes 36 are horizontally and movably arranged inside the detection slot. The moisture detection probes 36 are horizontally placed between the dairy product moisture detection chamber 19 and the detection slot for transfer. The end of the moisture detection probe 36 away from the dairy product moisture detection chamber 19 is connected to an electric telescopic rod 39, and the electric telescopic rod 39 and the water activity sensor 38 are electrically connected to the control module 41. The water activity sensor 38 is provided at the end of the electric telescopic rod 39, and the upper part of the water activity sensor 38 is connected to the moisture detection probe 36 through a telescopic connecting wire 37. When the dairy product inside the dairy product moisture detection chamber 19 is tested, the electric telescopic rod 39 is controlled to drive the moisture detection probe 36 to move toward the dairy product moisture detection chamber 19, and then the dairy product is tested for moisture, and the test results are displayed on the display screen 43 in real time;

[0024] Specifically, the water activity sensor 38, the electric telescopic rod 39, and the connecting wire 37 are all configured as waterproof structures. When the dairy products inside the dairy moisture detection chamber 19 penetrate around the water activity sensor 38, the electric telescopic rod 39, and the connecting wire 37, they will not be affected.

[0025] As a preferred embodiment of the present invention, see Figure 5 、 Figure 6 The stirring assembly includes a stirring and drying substrate 25 rotatably arranged at the bottom of the dairy product moisture detection chamber 19, a rotating motor 24 is connected to the middle part of the bottom of the stirring and drying substrate 25, and the rotating motor 24 is fixed in the rotating motor chamber 23 opened at the lower side of the moisture detection box 17. When the rotating motor 24 is started, the stirring and drying substrate 25 is driven to rotate. At the same time, a circle of sliders 26 are installed on the circumferential side walls of the stirring and drying substrate 25, and a circle of slide grooves 27 are opened in the inner wall of the dairy product moisture detection chamber 19 corresponding to the slider 26. The slider 26 is placed in the slide groove 27 and rotates, and the upper and lower sides are sealed to prevent the liquid inside the dairy product moisture detection chamber 19 from seeping into the rotating motor chamber 23; a plurality of obliquely distributed stirring and drying blocks 29 are annularly installed on the top of the stirring and drying substrate 25. When the stirring and drying substrate 25 rotates, it drives the stirring and drying blocks 29 to stir the dairy product inside the dairy product moisture detection chamber 19 and mix it evenly, so that the moisture detection probe 36 can accurately detect it.

[0026] As a preferred embodiment of the present invention, the drying component includes a heating resistance wire arranged inside the stirring and drying substrate 25, and the stirring and drying block 29 is made of heat-conductive metal. When the heating resistance wire is heated, the heat is directly transferred to the stirring and drying block 29, and then the residual moisture in the dairy moisture detection chamber 19 is dried by the stirring and drying block 29. The heating resistance wire is connected to a battery pack and a control board arranged inside the stirring and drying substrate 25. The control board is wirelessly connected to the control module 41 on the inner wall of the control module 41, and the start and stop operation of the heating resistance wire is controlled by pressing the switch 12.

[0027] As a preferred embodiment of the present invention, the top of the moisture detection box 17 is connected to a lifting mechanism box 18, and a servo motor 35 connected to the control module 41 is installed on the top of the lifting mechanism box 18. The bottom output end of the servo motor 35 is connected to a screw 32, and a nut 33 is threadedly connected to the screw 32. The nut 33 is provided with a guide device for limiting its rotation. A piston plate 30 is installed downward on both sides of the nut 33 through a connecting rod 34. The piston plate 30 moves up and down along the inside of the dairy moisture detection chamber 19 to control the flow of liquid between the stirring and drying substrate 25 and the piston plate 30. That is, when the piston plate 30 moves downward, the one-way pressure valve 28 inside the waste liquid discharge pipe 22 is pressurized and opened. At this time, the dairy moisture detection chamber 19 is opened. The liquid inside the detection chamber 19 is discharged through the waste liquid discharge pipe 22. At the same time, a group of elastic baffles 44 are swingably provided at the connection between the connecting pipe 20 and the dairy product moisture detection chamber 19. When the elastic baffles 44 are subjected to the pressure inside the dairy product moisture detection chamber 19, the connection between the connecting pipe 20 and the dairy product moisture detection chamber 19 is sealed. When the piston plate 30 is raised, the elastic baffles 44 are opened by suction, and then the cleaning liquid in the cleaning liquid box 40 is sucked into the dairy product moisture detection chamber 19. Then, under the rotation of the stirring and drying substrate 25, the inside of the dairy product moisture detection chamber 19 is cleaned, and then the waste liquid after cleaning is discharged again by the piston plate 30 falling, thereby realizing the automatic liquid inlet and outlet of the dairy product moisture detection chamber 19.

[0028] Specifically, in order to maintain sufficient contact between the piston plate 30 and the stirring and drying substrate 25, a stirring and drying block laminating groove 31 is opened at the bottom of the piston plate 30 corresponding to the stirring and drying block 29, and the stirring and drying block 29 is laminated with the stirring and drying block laminating groove 31;

[0029] It should be noted that the one-way pressure valve 28 inside the dairy product input pipe 21 is still in a closed state when it is subjected to the adsorption force in the dairy product moisture detection chamber 19, and its pressure opening can only be applied from the inlet end of the dairy product input pipe 21.

[0030] The working principle of the present invention is: in the idle place of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. During operation, hold the handle 11 and input the dairy product to be tested into the dairy product moisture detection chamber 19 along the dairy product feed port 14, then start the rotating motor 24 to drive the stirring and drying base plate 25 to rotate, drive the stirring and drying block 29 to stir and mix the dairy product, and then start the electric telescopic rod 39 to drive the moisture detection probe 36 to extend to the dairy product In the moisture detection chamber 19, the moisture content of dairy products is detected, and the detection results are displayed in real time on the display screen 43. Then, the servo motor 35 is started to control the stirring and drying substrate 25 to descend, and the dairy products are discharged along the waste liquid discharge pipe 22 and the waste liquid discharge port 15 by using pressure. Then, when the stirring and drying substrate 25 is raised, the connecting pipe 20 is connected with the dairy product moisture detection chamber 19, and the cleaning liquid in the cleaning liquid box 40 is input into the dairy product moisture detection chamber 19, and then it is stirred and cleaned by the stirring and drying block 29. Then, the stirring and drying substrate 25 is lowered again to discharge the waste liquid. After repeated cleaning, the heating resistance wire is started to use the stirring and drying block 29 to dry the inside of the dairy product moisture detection chamber 19.

[0031] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
