[0002] Food additive detection and extraction is an important part of ensuring food safety and quality. During the extraction process, although some impurities can be removed, it is often impossible to completely remove all unwanted components due to limited selectivity. In the food industry, extraction is the process of initially separating sample substances from raw materials. This step usually involves physical or chemical methods to obtain a crude extract containing the target substance.

[0003] However, in actual production, when processing samples of semi-solid food additives, due to the particularity of their physical properties, fine particles may cause blockage of connecting pipes during the subsequent extraction process.
