[0002] Food detection is to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products according to the formulated technical standards to ensure that the product quality is qualified. The content of food inspection includes the sensory detection of food, the detection of nutrients, additives and harmful substances in food, etc. During the food detection process, there are impurities in some foods. In order to avoid affecting subsequent detection, it is necessary to screen and filter out the impurities in the food through a sample impurity separation device, so as to separate the sample and the impurities from each other.
