What metals can be detected and rejected by metal detectors ? Which machine can be used for detecting aluminum foil packaging products ? The above mentioned top curiosity as well as common knowledge of metal and foreign body inspection will be answered here.
The cantering industry definition
The catering industry (catering) is a food production and management industry that provides consumers with all kinds of drinks, food, consumption places and facilities through instant processing, production, commercial sales and service labor. According to the European and American Standard Industry Classification, the catering industry is a catering service organization.
What solutions can Techik provide for catering industry?
We believe that the central kitchen of the catering industry adopts the food factory production mode for production. Analyze the production process, in the raw material link or in the finished product link, or for a certain large amount of products for industrial production, it is possible to use detection equipment (metal detectors, X-ray inspection systems and checkweighers) in the production process.
Raw material detection: Vegetables, fruits, meat, etc. can be detected. Appropriate detection equipment (metal detectors, X-ray inspection systems and checkweighers) will be optional for different detection products.
Finished product detection: processed semi-finished products, processed box lunch, etc
Related detection equipment (metal detectors, X-ray inspection systems and checkweighers)
Metal detector: non-aluminum foil packed box lunch, semi-finished dishes can be detected by metal detectors, which can normally detect black and colored metals and also stainless steels. The sensitivity of metal detectors differentiates according to the series of metals. The detection difficulty depends on the metal magnetic conductivity and electric conductivity.
| Metal Character | Magnetization | Electric Conductivity | Detection Difficulty |
| Black Metal（Ferrum） | Strong | Good | Easy to be detected |
| Colored Metal（Copper、Aluminum） | Non-magnetic | Perfect | Relatively easy to be detected |
| Stainless 304, 316… | Normally Non-magnetic | Normally poor conductivity | Relatively hard to be detected |
Checkweigher : various models are optional for different products in different size and weight. Suitable for weight checking for packaged products, to ensure quality standards.
X-ray inspection system : X-ray inspection system can solve the problem of aluminum foil packaging products. Moreover, in case that the sensitivity of the metal detection machine can not meet the requirements due to the large effect of the product, the X-ray inspection system can get a good metal detection accuracy. Further more, X-ray inspection system can detect other hard foreign bodies such as glass, stone, etc.
