In the field of food production, ensuring product safety and preventing the mixing of metal foreign objects are of utmost importance. Qingdao Electronic Testing, with its profound technological accumulation, has launched a food metal detector that provides excellent performance to build a strong safety defense line for the food industry.
Innovative working principle, precise targeting of metal impurities
The food metal detector of Qingdao Electronic Testing operates based on the principle of electromagnetic induction. The device is equipped with a transmitting coil and a receiving coil, and the transmitting coil is driven by an oscillator to generate a high-frequency variable magnetic field. Under normal conditions, the induced voltages of the receiving coils cancel each other out and maintain balance. Once there are metal foreign objects in the food passing through the detection area, the metal will cut the magnetic field lines, causing eddy currents and generating a reverse magnetic field, breaking the original balance. The unbalanced signal of the induced voltage in the receiving coil is captured by the control system, amplified and processed. If it exceeds the preset threshold, an alarm is immediately triggered to accurately extract metal impurities and prevent them from flowing into subsequent production processes or reaching consumers.
Diversified technological advantages, meeting the stringent production requirements
High sensitivity detection, not overlooking subtle hidden dangers
The detector adopts advanced multi frequency electromagnetic field technology and can sensitively detect metal particles with a minimum diameter of 0.3mm for ferromagnetic substances; For non ferromagnetic metals such as copper and aluminum, tiny foreign objects up to 0.5mm can also be identified, covering various common metal impurities from multiple directions. Even in complex food matrices, it can ensure "sharp observation". At the same time, the automatic phase compensation function suppresses environmental electromagnetic interference in real time, significantly reducing false alarm rates and ensuring the authenticity and reliability of detection results.
Intelligent linkage enhances production efficiency
After detecting metal foreign objects, the equipment quickly triggers the removal device, such as pneumatic push rods, flipping mechanisms, etc., to quickly remove the problematic products from the production line, and the entire process is completed in one go. Not only that, it also supports seamless linkage with the PLC system of the production line, ensuring that filling, sealing and other processes are not affected, guaranteeing the continuous and efficient operation of the production line, while improving product quality without reducing production efficiency.
Food grade design, strict adherence to hygiene standards
The detection channel of the detector is made of food grade stainless steel or polymer materials, with a smooth surface that is difficult for microorganisms to adhere and grow, and is convenient for daily cleaning. The waterproof and dustproof rating of the equipment is above IP65, and it still operates stably in the face of common high temperature and high pressure cleaning environments in food factories, meeting the strict hygiene requirements of food production workshops.
Widely applicable scenarios, covering the entire food category
In meat processing, it can accurately identify metal debris caused by tool wear in minced meat and sausages; When baking food production, effectively detect foreign matters such as wires and screws in flour and biscuits; In the field of frozen food, final inspection is carried out for frozen dumplings, pre made dishes, etc. to intercept metal impurities mixed in; During the packaging stage of finished products, the sealing caps and packaging films of canned beverages and vacuum bagged foods are scanned to ensure that there is no risk of metal contamination throughout the entire process from raw materials to finished products.
Qingdao Electronic Food Metal Detector, with its cutting-edge technology and reliable performance, has become a powerful assistant for quality control of many food enterprises, safeguarding consumers' food safety and promoting the high-quality development of the food industry.
