In today's highly developed material civilization and spiritual civilization, food and drug safety is a major concern of the country, society and people. It is also a major issue related to product quality and enterprise survival and development.

In order to ensure product quality and prolong the shelf life of products, many products are packaged with aluminum film/aluminized film material. Since aluminum film is also metal, traditional metal detectors cannot be used, which brings security risks to the detection of foreign objects in products. A lot of product quality headaches.

As a domestic manufacturer of foreign object detection equipment such as food X-ray machines and metal detectors, and a veteran with more than 20 years of industry experience, we will work with you to analyze and find the best solution for foreign object detection in aluminum film/aluminized film packaging products.

one. Problem description: In order to ensure food and drug safety, aluminum film/aluminized film packaging products have aluminum waist problems (aluminum film is also metal). Traditional metal detectors cannot be used, and there are potential safety hazards when products flow into the market.

two. Solution

Here we have a targeted analysis of several common foreign body detection equipment (metal detectors/food X-ray machines) at home and abroad.

1. Magnetic Metal Detector.

This product actually uses the principle of magnets. A magnet is installed in the detector head of the metal detector, which generates a strong magnetic field after being energized. thereby calling the police. (In fact, it is the needle detector commonly used in clothing factories to detect broken needles in clothing).

Magnetic metal detectors can only detect ferrous metal foreign bodies in food, and metals other than iron cannot be detected. In addition, the magnetic decay of magnets is relatively fast, and then the sensitivity decays relatively quickly.

It only plays a role in meeting the requirements of customers in the quality system and the inspection of relevant departments, but it cannot solve the hidden safety problems of products. It is not recommended for food and drug companies to use it.

2. Imported aluminum film metal detector

This product is imported equipment, which can detect iron and stainless steel with low purity, but cannot detect other metals. Even if stainless steel is detected, the sensitivity is not high, and stainless steel balls under 3.0mm are basically undetectable. Occasionally seen in some wholly foreign-owned enterprises or brand enterprises. The price is relatively expensive, generally above 150,000, and the use effect is not very good, so it is not accepted by the Chinese market and is basically eliminated at present.

3. Food X-ray machine

Using the X-ray perspective principle, when the X-ray of the food X-ray machine penetrates objects of different densities, the product has different image characteristics, and the intelligent AI algorithm is used to find the metal and non-metallic foreign bodies in the aluminum film/aluminized film packaging products, And output an alarm signal, and then through the automatic rejection device, the products containing foreign matter are removed.

The biggest feature of the food X-ray machine is that it can not only detect all metal impurities such as iron, stainless steel, copper, etc. in aluminum film/aluminized film packaging products, but also non-metallic foreign objects such as stones, male bars, glass, glue, and bones. Moreover, the packaging material of the aluminum film/aluminized film does not affect the detection effect of the X-ray machine on the product.

Food X-ray machine is the best choice to solve product foreign body, and it is also the mainstream product for foreign body detection in the future.
