[0045] It should be noted that the base is designed to be sturdy and stable during use, preventing measurement errors caused by shaking. The scale platform utilizes high-precision load cells, accurately measuring food weight and ensuring reliable weighing results. The support structure is constructed of sturdy metal, ensuring not only the durability of the scale but also its adaptability to various operating environments. The display features a high-resolution touchscreen, allowing users to intuitively view weighing data and operate the interface. The image acquisition unit includes a high-definition camera, capturing real-time images of food. The main control circuit board is the core of the smart scale, processing data from various sensors and devices and performing comprehensive analysis.

[0046] It's also worth noting that by leveraging the characteristics of shortwave infrared, rapid, non-destructive testing of food ingredients, freshness, and safety can be achieved. First, shortwave infrared technology can detect moisture content in food. Moisture is a key factor affecting food quality. By analyzing the absorption of infrared light at different wavelengths, the moisture content of food can be accurately measured. This is particularly important for quality control of dried, frozen, and baked goods. Second, shortwave infrared technology can be used to measure the fat content in food. Fat not only affects the taste and nutritional value of food but can also have adverse health effects. Using shortwave infrared spectroscopy, fat content can be quickly determined in food, helping manufacturers optimize recipes and ensure product quality. Furthermore, shortwave infrared technology can be used to measure protein content in food. Protein is a key nutrient in food, and its content and quality directly impact its nutritional value. Shortwave infrared spectroscopy can accurately measure protein content in food, providing important evidence for food quality assessment. Finally, shortwave infrared technology also offers significant advantages in detecting harmful substances in food. For example, infrared shortwave spectroscopy can be used to detect pesticide residues, heavy metal content, and other harmful substances in food. This is of great significance for ensuring food safety and protecting consumer health.

[0047] Due to their high frequency and short wavelength, millimeter waves can penetrate certain materials and detect subtle changes within food. This characteristic gives millimeter wave technology unique advantages in food safety and quality testing. First, millimeter waves can be used to detect moisture content in food. Moisture is a key factor affecting food quality and shelf life. By measuring the dielectric properties of food in the millimeter wave band, its moisture content can be accurately assessed. This is particularly important in industries such as grain storage, food processing, and baking.

[0048] Secondly, millimeter wave technology can be used to detect impurities and foreign matter in food. For example, during grain processing, millimeter wave sensors can detect foreign matter such as stones and metal fragments that have entered the grain. Because millimeter waves have different penetration and reflection characteristics for different substances, these impurities can be effectively identified and separated. Furthermore, millimeter wave technology can be used to examine the internal structure and uniformity of food. For example, during meat processing, millimeter wave imaging can be used to detect the distribution of fat and the uniformity of muscle tissue within a cut of meat. This is crucial for ensuring the taste and nutritional value of food. Finally, millimeter wave technology also has broad application prospects in food safety testing. For example, millimeter wave sensors can be used to detect bacterial and viral content in food. Because bacteria and viruses affect the propagation characteristics of millimeter waves, the sanitary condition of food can be assessed by analyzing changes in millimeter wave signals.

A person skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present invention.
