Scope of application of food metal detector

One. Scope of application: Food metal detectors are mainly used in: sauces, sausages, dumplings, hams, soups, candy, preserved foods, salted foods, fast foods, food additives, starch, glucose, tobacco, fresh meat, dairy products and other industries, It is suitable for product detection with strong product effects and other industries that have high requirements on detection sensitivity, anti-interference ability and waterproofing. It is used to detect broken needles, wire or lead, copper, copper, Various metals such as aluminum, tin and stainless steel. Food metal detector can also be used to detect ferrous and non-ferrous metal impurities in foods such as meat, fungi, candy, beverages, food, fruits and vegetables, dairy products, aquatic products, health products, additives and condiments. Second. Performance characteristics: 1. Adopt balanced principle, more stable and reliable, and better performance; 2. Phase adjustment technology enables product adjustment and effectively suppresses product effects; 3. The combination of DSP and MCU performs data sampling and data processing on the detection signal, which improves the detection effect; 4. The direct digital frequency generator generates a sine wave with adjustable frequency, phase and amplitude, which changes the analog circuit parameters difficult to adjust and cooperate with, and can easily adjust various parameters such as sensitivity; 5. LCD display panel, Chinese and English operation menus, users can choose according to their needs, with a good man-machine dialogue interface; 6. One-click product features self-learning function, intelligent and fully automatic learning and memory product features, no manual adjustment of parameters, simple operation; 7. With 100 kinds of product parameter memory function, it can store the detection parameters of 100 kinds of products, no need to adjust again after one setting, it can be called when testing products; 8. The lever automatically removes defective products, saving labor costs and improving production efficiency. Sensitivity depends on two factors: aperture size and operating frequency. The smaller the aperture, the higher the sensitivity of the probe. For example, a hole with a height of 50 mm will only be able to detect 0.5 mm of metal. Secondly, the higher the frequency, the higher the sensitivity. However, increasing the frequency does not automatically mean improving the detection capability, because it may cause the food itself to generate a strong signal to the detector, which is often referred to as the product effect. Therefore, our goal is to determine a maximum frequency that does not seem to fail. In this way, the detector can detect contaminants and will not send false alarms. In order to obtain the best results, the specific test parameters of each product to be tested should be determined and automatically recorded and retained. The industry standard used to test the performance of metal detectors is the size of various metal balls detected by the detector. But in fact, the shape of the contaminants may be fragments of metal wires or metal plates. They generate different signals to the detector according to the position in the detector aperture, the so-called azimuth effect.
