The working principle of the food X-ray machine is to use the penetration ability of X-rays to scan and detect food. It can detect various foreign objects in food, such as metal, glass, plastic, bone, etc., which may pose a serious threat to the health of consumers. At the same time, the food X-ray machine can also detect the internal structure and quality of food, such as whether there are cavities, cracks, deterioration and other problems. Food X-ray machines offer a number of advantages over traditional inspection methods. First of all, it is a non-destructive testing method that can be inspected without destroying the food, ensuring the integrity and safety of the food. Secondly, the detection speed of the food X-ray machine is fast and the accuracy is high, which can detect a large number of foods in a short time and improve the production efficiency. In addition, the food and X-ray machine can also realize automatic detection, which reduces the error and labor intensity of manual operation. In food production enterprises, food X-ray machines have become indispensable testing equipment. It can detect food in real time on the production line, find and reject products containing foreign substances in time, and ensure product quality and safety. At the same time, the food X-ray machine can also provide enterprises with data support for quality control and management, help enterprises optimize the production process and improve product quality. In addition to their application in food production enterprises, food X-ray machines also play an important role in food regulatory authorities. The regulatory authorities can use food and Yiguang machines to conduct random inspections on food on the market, find substandard products in a timely manner, and protect the legitimate rights and interests of consumers. The detection results of the food X-ray machine are accurate and reliable, which can provide strong technical support for the regulatory authorities and strengthen the supervision of food safety. However, there are some issues that need to be noted when using a food X-ray machine. First of all, the operators of the food X-ray machine need to be professionally trained to master the correct operation methods and safety precautions. Secondly, the radiation dose of food X-ray machines needs to be strictly controlled to ensure safety for the human body and the environment. In addition, the test results of food X-ray machines need to be scientifically analyzed and judged, and decisions cannot be made solely based on the test results of the equipment. In short, as a high-tech testing equipment, food X-ray machine provides a strong guarantee for food safety. In the future development, with the continuous progress of science and technology, the performance and function of food X-ray machine will continue to improve, building a more solid line of defense for food safety.
