Food metal detector
Food Metal Detector, or food metal detector, is an instrument specifically used to detect metal impurities in food. The following is a detailed description of the instrument:
1. Definition and function
Food metal detectors use the principle of electromagnetic induction to detect iron and non-iron metal impurities in food, such as nails, screws, metal fragments and so on. These impurities may come from contamination in production equipment, packaging materials or processing, posing a potential threat to food safety.
2. Working principle
The working principle of food metal detectors is based on electromagnetic induction. When the metal enters the detector's detection area, it changes the magnetic field distribution in the area, which triggers the detector to issue an alarm signal. Specifically, the entry of ferromagnetic metals into the detection area will affect the distribution of magnetic field lines, and non-ferromagnetic metals will produce eddy current effects, both of which will cause the detector to emit a buzzer or alarm signal.
3. Structure composition
Food metal detectors are usually composed of a detection head, a control panel, a transmission system and an automatic culling system. The detector head is the core part of the detector, which is responsible for detecting metal impurities in food. The control panel is used to set detection parameters and display detection results. The transmission system is responsible for transporting the food to be tested to the test area; Automatic removal systems automatically remove metal impurities from the production line when they are detected.
4. Application field
Food metal detectors are widely used in the production process of meat, fungi, candy, beverages, food, fruits and vegetables, dairy products, aquatic products, health products, additives and condiments and other food industries. In addition, it can also be used for chemical raw materials, rubber, plastic, textiles, leather, chemical fiber, toys, medicine, biological products, cosmetics, gifts, packaging, paper products and other industries of metal impurity detection.
5. Significance
The application of food metal detector is of great significance. First of all, it can effectively prevent food containing metal impurities from entering the market and ensure the dietary safety of consumers. Secondly, by detecting and controlling the content of metal impurities in food, public health and social stability can be maintained. In addition, the use of food metal detectors also helps to improve the production efficiency and product quality of the food industry, and promote the healthy development of the food industry.
6. Market status
At present, there are many types of food metal detectors on the market, with prices ranging from several hundred yuan to tens of thousands of dollar. Different brands and models of detectors have differences in detection accuracy, stability, ease of use and so on. Consumers should make comprehensive consideration according to actual needs and use scenarios when choosing.
In summary, as an important Food safety detection tool, Food Metal Detector plays an important role in ensuring food safety, maintaining public health and promoting economic development. With the continuous progress of science and technology and people's increasing attention to food safety issues, the application prospect of food metal detectors will be broader.
