Food safety issues mainly include the following aspects: chemical hazards, biological toxins, microbial hazards, food adulteration and safety issues of genetically engineered foods. Ensuring food safety is an important function of the food and drug supervision and administration department, so it is necessary to test food. The filtration device used in food testing is a device used to separate, clarify or purify different components in a sample, especially suitable for removing suspended solids and macromolecular substances in the sample or pre-treatment before liquid extraction. This type of device can help obtain purer analytes during the detection process, which is crucial to improving the accuracy of the detection. During the use of the existing filtration device for food testing, when filtering the material, it only relies on the weight of the material, and the filtration effect of the device is low, thereby reducing the filtration efficiency of the device.

[0003] For example, the utility model with announcement number CN213589879U discloses a filtering device for food detection. The technical solution of this patent includes a box body, a box door, a filter screen and a collection box.

During the use of this device, it can be found that the filtering effect of the filtering device for filtering materials solely relying on the weight of the material is low, thereby reducing the overall filtering effect of the device. Therefore, a filtering device for food detection is proposed. Utility Model Content

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, when the device needs to be filtered, the material is first added from the inside of the hopper. At this time, the material is passed into the inside of the frame through the feed pipe, so that the material flows onto the filter plate. At this time, under the action of gravity, the connecting plate drives the spring to press, thereby completing the filtering of the material.

[0010] Secondly, start the rotating motor, and the rotation of the rotating motor drives the synchronous pulley 2 to rotate. The rotation of the synchronous pulley 2 drives the transmission belt to move, thereby driving the moving block to move, so that the moving block drives the slider to slide inside the slide groove, thereby driving the moving plate to move, and then driving the pressure plate connected to the moving plate to press the material inside the frame, thereby improving the overall filtering efficiency of the device.

[0011] Thirdly, when the pressure plate moves downward, the frame drives the connecting plate to move downward, thereby driving the spring to move downward, thereby pressing the material. The spring acts as a buffer to prevent damage to the device. At this time, the feed pipe moves inside the guide groove.

[0012] Fourthly, the design of the observation window makes it convenient for the staff to observe the internal mechanism of the box, so that they can make the first response when there is any problem with the internal mechanism of the box. BRIEF DESCRIPTION OF THE DRAWINGS
