[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking. In order to protect human health, food needs to be tested during the food production process.

[0003] In the prior art, there is a food detection device and detection method with announcement number CN 116718738 B. The food detection device includes a base, a box, a door, a placement component, a pushing component, a delivery component and a pressing component. The upper part of the base is fixedly connected to the box by screws, and the front and rear sides of the box are rotatably connected to doors with handles by hinges. A placement component for placing food is arranged at the lower part of the box, a pushing component is installed on the left side of the box, and a delivery component for delivering medicine is connected to the top of the box. The pushing component is connected to the delivery component, and the pushing component can push the delivery component. The delivery component is connected to a pressing component for controlling the feeding. After the food is placed in the placement component, the subsequent detection of the food is carried out in the box, which reduces the influence of the outside world on the food detection results and ensures the accuracy of the food detection results.

[0004] However, when the above-mentioned food detection device is in use, although food can be placed in the device for sealing detection operation, when different types of food are detected, different foods are often detected through a single medicine box, and the detection effect of switching different medicine boxes for different foods is not high. Moreover, when the medicine boxes are converted for use, the synchronous protection effect of the detection nozzles in the corresponding storage state is not high, so that when a single medicine box is used for a long time, there is drug mixing, which affects the accuracy of different food detection data.

10. A detection method for a food detection device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step S1, after placing the culture dish (3) on the sliding table (2), the first servo motor (1001) is turned on to drive the worm wheel (1003) to rotate through the rotation of the worm (1002), and the rotation of the worm wheel (1003) drives the adjustment plate (1005) to slide synchronously along the limit groove (1006) and the outer wall of the adjustment box (7) through the rotation of the swing rod (1004), so that one group of adjustment boxes (7) is in an open state and the other group of adjustment boxes (7) is in a closed state, and the medicine in the medicine box in the open state flows out through the nozzle, so as to meet the needs of different food conversion detection; Step S2, when one group of adjustment boxes (7) is opened and the other group of adjustment boxes (7) is closed, the nozzle corresponding to the closed adjustment box (7) will move to the storage position. At the same time, the rotation of the swing rod (1004) drives the first threaded rod (1101) to rotate.
