The side wall of the soybean oil sample cylinder 1 is provided with volume scale lines 11 to facilitate quantitative sampling. A temperature sensor 12 is installed on the side wall of the soybean oil sample cylinder 1. A cylinder cover 2 is hinged to the upper end of the soybean oil sample cylinder 1.

[0029] like Figure 1 and Figure 2 As shown, a through hole 21 is provided in the middle of the cylinder cover 2, and the electrode head 29 is located directly above the through hole 21. A threaded rod 22 is provided on one side of the upper end of the cylinder cover 2 via a bearing, and a guide rod 23 is fixedly connected to the other side of the upper end of the cylinder cover 2. A support plate 24 is provided on the top side of the threaded rod 22 and the guide rod 23. A through hole 241 is provided in the middle of the support plate 24, and the diameter of the through hole 241 is the same as the diameter of the limiting groove 251. A knob 26 is rotatably connected to one end of the support plate 24, and the knob 26 is connected to the top of the threaded rod 22. An installation plate 25 is sleeved on the outside of the threaded rod 22 and the guide rod 23. By hinged to the cylinder cover 2 on the soybean oil sample cylinder 1, the soybean oil to be tested can be contained. The threaded rod 22 and the guide rod 23 are driven to raise and lower the electrode head 29, which makes it easy to adjust the height of the electrode head 29 according to the amount of soybean oil, and has good flexibility.

[0030] like Figure 3 and Figure 4 As shown, a limiting groove 251 is formed in the middle of the mounting plate 25, and a through hole 255 is formed on the bottom side of the limiting groove 251. An insertion hole 252 is formed in the middle of both the front and rear ends of the mounting plate 25. Mounting holes 253 are formed on the left and right sides of both the front and rear ends of the mounting plate 25. A magnet 254 is set in each mounting hole 253. A positioning plate 27 is embedded in the limiting groove 251. An electrode head 29 is fixedly connected to the bottom of the positioning plate 27. An insertion hole 271 is formed in the middle of both the front and rear sides of the positioning plate 27. An insertion rod 2 is inserted between the insertion hole 271 and the insertion hole 252. 8. Arc-shaped plates 281 are fixedly connected to the outer side of the insertion rod 28.

[0032] This utility model provides a soybean oil acidity analysis and detection device. The specific working principle is as follows: A certain amount of soybean oil is poured into the soybean oil sample cylinder 1, the cylinder cover 2 is closed, and the user rotates the knob 26 to drive the threaded rod 22 to rotate, so that the mounting plate 25 moves on the threaded rod 22 and the guide rod 23, thereby allowing the electrode head 29 to pass through the perforation 21 to enter the oil sample for detection. The temperature sensor 12 collects data synchronously, and the electrode head 29 feeds back the detection results to the control unit 3 and displays the detected acidity value on the display module 31. After the detection is completed, the insertion rod 28 is pulled out, so that the positioning plate 27 and the mounting plate 25 are released from the limit, and the electrode head 29 is pulled up to be taken out, which facilitates the cleaning of the electrode head 29. The cylinder cover 2 is then opened to clean the inner wall of the cylinder cover 2.
