In recent years, the scale and brand of the meat industry have gradually increased, and the market demand for meat products has also grown rapidly. On this basis, consumers are increasingly demanding the quality of meat products.
In the raw materials, processing, packaging and other links, the meat processing industry has the possibility of metal foreign matter contaminating the production line. The foreign matter problem has become a stubborn problem of damaged brand image and consumer complaints.
Metal detectors use the principle of electromagnetic induction, combined with automatic removal devices, to remove food containing metal foreign bodies. In order to control the risk of metal foreign bodies in the production process, metal detectors are becoming more and more common in the meat processing industry.
Factors such as meat product effects make foreign metal detection challenging. Processors are more cautious when buying metal detectors. How to buy a metal detector? It mainly includes the following three aspects:
1. Sensitivity
Sensitivity is the core of measuring the quality of metal detectors. For example, the sensitivity in the metal detector manual is as follows 0.5mm, it refers to the diameter of a certain metal ball that the device can detect without simultaneously delivering 0.5mm of material.
This way of expressing sensitivity is often misleading, like a 0.1mm sphere is 0.1mm different in diameter than a 0.2mm sphere, which seems to be the same, but it's not. The volume difference between the two spheres is 8 times, and the actual detection effect is incomparable.
The increase in device sensitivity is proportional to the increase in production cost. Higher sensitivity means better equipment materials, more and better investment in production equipment, more complex processing processes, greater technical difficulty, more complex technical solutions, and higher production reference standards.
The use process of the equipment is also the process of the equipment aging and gradually deviating from the normal working state. High sensitivity means large margins and strong bias capability.
2. Equipment stability
Factors such as external interference, workshop environment, type of meat products, packaging materials, etc. can affect the actual operation of the metal detector. Therefore, relevant processing enterprises need to choose a more stable metal detector according to their actual situation.
The metal detector has high stability, the number of false alarms, the number of detections, the false alarm rate, the detection rate and other indicators meet the requirements, and the performance indicators are stable and reliable.
3. Equipment material
In order to avoid risks such as secondary pollution of meat products, relevant processing enterprises have put forward higher requirements for the body material and structural design of testing equipment. In general, waterproof, dustproof, and corrosion-resistant materials and designs are preferred.
Shanghai Leding has been focusing on multi-spectral, multi-energy spectrum, and multi-sensor technology routes for more than ten years, and has insight into foreign body risks in all aspects of meat processing, providing meat processing enterprises with metal detectors with higher sensitivity and more stable operation.
Shanghai Leding metal detector has the functions of phase tracking, product tracking, automatic balance correction, etc., which improves its detection sensitivity and stability, and has a wider detection range. The optimized circuit structure can maintain constant detection accuracy in the fast range.
Two-way detection, high and low frequency switching and other functions improve the detection performance and adaptability of the device. For meat products with many varieties and large differences, the detection of different frequencies can be replaced to improve the detection effect.
The one-key self-learning function of the product makes the operation of the equipment easier. The stainless steel body, food-grade conveyor belt, and various disassembly devices make the equipment safer and more reliable and have a wider range of applications. Customer-centric after-sales service helps enhance the customer experience.
