Application Of Metal Detector In Meat Production Process

- Apr 04, 2019-

With the rapid economic growth, the meat processing industry in China will develop in the direction of safety, hygiene, convenience, rapidity, nutrition and commercialization in the coming years. The proportion of chilled meat, small packaged meat and various meat products in the market will also increase rapidly. Relevant departments forecast that the annual growth rate of meat consumption in China will reach more than 5%.

Increased security requirements

On the other hand, in order to enhance market competitiveness, meat manufacturers strive to obtain green passes to enter the international market, and pay more and more attention to the implementation of HACCP certification system. Driven by the above background, meat processors have begun to introduce metal detectors into their production lines to improve the safety of meat products, ensure product quality and enhance customer confidence.


Metal inspector is mainly used for on-line detection of metal impurities in raw meat or meat products, including iron, non-ferrous metals and stainless steel. The sources of these metal impurities are mainly classified into several categories, including metal labels, needles and wires in raw meat, personal articles of operators, such as coins, keys, hairpins, thumbtacks, etc., and impurities produced by machinery and equipment in the production process, such as metal debris caused by machine damage in the process of raw meat cutting, crushing or mixing.



Necessary Characteristics

In order to detect the metal impurities mentioned above, it is an economical and practical method to install metal detector in the production process. The metal detector used in meat processing industry must have the following characteristics:


Use environment: Meat products are edible products, so there is a higher requirement for the production of hygienic conditions. Washing equipment with tap water (or even high-pressure water) is a common cleaning method, which requires metal detector to have anti-washing function, such as stainless steel shell, IP65 waterproof grade, etc.


Meat product itself: Because raw meat or meat product itself is an electrical conductor, product signals will be generated when passing through the metal detector. Needle detector interferes with the normal operation of the metal detector. This requires that the metal detector has the function of overcoming the interference of product signals and correctly detecting metal impurities.


Equipment Installation Form: Because there are many links in raw meat food processing, such as raw meat, meat mince and so on, different types of metal inspectors and installation methods should be used for different meat products, so the supplier of metal inspectors should have a variety of equipment for selection.
