High Speed Food Metal Detectors Can Detect Metal Impurities of Different Sizes, Shapes and Densities

Jul 05,2024

The design and technology of high speed food metal detectors enable them to detect metal impurities of different sizes, shapes, and densities, thereby ensuring the safety and quality of food.

High speed food metal detectors can detect very small metal particles, usually metal fragments with a diameter as small as 0.2 millimeters or even smaller. This is very effective for detecting fine metal shavings and powdery metal pollutants. For larger metal objects such as screws, bolts, metal tool components, etc., it can also effectively identify and remove them.

The high speed food metal detectors can not only detect irregularly shaped metal fragments generated during the production process, such as metal shavings and fragments caused by wear, but also detect some special shaped metal impurities, such as metal wires, metal strips, slender metal fragments, etc., through sensitive transducer technology. It can also effectively identify aluminum foil fragments, thin metal fragments, etc. through advanced detection technology.

Food metal detection machines can easily detect high-density metal impurities such as iron, steel, stainless steel, etc. It can also effectively detect these low-density metal impurities, such as aluminum, copper, etc., by adjusting sensitivity and using multi frequency technology.

The food metal detection machine mainly works through electromagnetic induction technology. When metal impurities pass through the detection area, they will change the characteristics of the electromagnetic field, generate signal changes, and the detection function can capture these changes and identify them. The sensitivity can be adjusted according to different food products and production environments to ensure effective detection of various sizes, shapes, and densities of metal impurities.

Multi frequency detection technology allows high sensitivity metal detection machines to simultaneously use multiple frequencies for detection, thereby optimizing the detection ability for different metal types. High frequencies are more sensitive to small metal fragments, while low frequencies are more effective for large metal objects. This technology can significantly reduce false alarm rates and improve detection accuracy, especially in complex production environments.

The high sensitivity food metal detector is equipped with an automatic removal system, which can quickly remove contaminated products from the production line once metal impurities are detected, ensuring that qualified products on the production line are not interrupted. The automatic removal system improves the efficiency and reliability of the detection process, reduces manual intervention and operational errors.

Application examples:

·Baking food: Metal fragments may be mixed in the production process of products such as bread and cake, and the testing machine can ensure that there is no metal contamination before packaging.

·Dairy products: In liquid foods such as milk and yogurt, the high sensitivity metal detector can identify and eliminate small metal particles.

·Canned food: During the canning process, a high sensitivity metal detector can detect metal foreign objects in the can lid or inside the can.

·Frozen food: When packaging frozen food, the testing machine can ensure that the packaging materials or production equipment do not cause metal contamination.

high sensitivity metal detector application

The high speed food metal detector provides multi-level safety assurance in the food production process by detecting metal impurities of different sizes, shapes, and densities. Its efficient and accurate detection technology not only improves production efficiency, ensures product quality and safety, but also reduces potential consumer risks and economic losses. By continuously improving and applying advanced detection technologies, the food industry can achieve higher production standards and sustainable development goals.
