[0088] Detection Methods

[0089] The present invention also discloses a multi-parameter integrated rice quality rapid detection method, comprising the following steps:

[0090] Put in the sample: Pour the rice sample into the black material tray 2332, and clamp the black material tray 2332 in the receiving hopper 2331 through the spring sheet 2337.

[0091] Appearance and chalky grain rate detection: Under the joint action of the rotary worktable 21 of the rotary transport module 2 and the upper linear module 23, the black material tray 2332 moves to the bottom of the appearance detection module 3, with the ring lighting 35 as the light source; the background color of the black material tray 2332 enables the appearance detection camera 33 to accurately identify the appearance contour of the rice, thereby judging the appearance quality and the chalky grain rate.

[0092] Moisture detection: Under the joint action of the rotary workbench 21 of the rotary transport module 2 and the upper linear module 23, the black material tray 2332 moves to the bottom of the moisture detection module 4, and the moisture sensor 45 is driven by the moving module 43 and inserted into the black material tray 2332 to complete the moisture detection.

[0093] Turning the material: The light from the ultraviolet lamp 55 of the chalky particle rate detection module cannot pass through the black material tray 2332 , so the upper linear module 23 and the lower linear module 22 move to the same position, and the turning motor 2334 drives the receiving hopper 2331 to pour the rice sample into the transparent silo 225 .

[0094] Detection of amylose content: The vertical cylinder 224 rises, and under the joint action of the rotary workbench 21 of the rotary transport module 2 and the lower linear module 22, the transparent silo 225 moves to between the ultraviolet lamp 55 and the optical sensor 53, and the amylose content of rice is detected based on the difference in spectral absorption characteristics between amylose and amylopectin.

[0095] Detection of staling odor: Under the joint action of the rotary worktable 21 of the rotary transport module 2 and the lower linear module 22, the transparent material bin 225 moves to the bottom of the closed detection tank 63, and the vertical cylinder 224 rises, so that the transparent material bin 225 is close to the bottom opening of the closed detection tank 63; the closed detection tank 63 is equipped with a heating device and an electronic nose. After heating to 50°C for 10 minutes, the electronic nose is used to detect the content of aldehydes, heterocyclic compounds and alcohol compounds in the closed detection tank 63 to judge the quality of rice.

[0096] Completion of the test: Under the joint action of the rotary workbench 21 of the rotary transport module 2 and the lower linear module 22, the transparent silo 225 moves to the transparent hatch 11, the transparent hatch 11 is opened, the rice sample is taken out, and the test is completed.
