Metal detection equipment is widely applied in industries related to food, medicine, chemical and plastic industry. Each industry's products and testing requirements are different, so choose the industry's appropriate metal detector.

There are many categories in the food industry. According to the the state of products, there are two kinds of products that are dry and wet products. Dry products do not contain water quality and are easy to detect. In the selection of equipment types, conventional products can be chosen. According to the shape of the product, choose the corresponding kind of machine, generally pouch packaging food, such as: bread, biscuits and candy, etc., can choose conveyor metal detector to match with the production line. Placed at the end of the production process, enter the warehousing directly after detecting. For dry particles and powder products, a free fall metal separator is required, products are separated by an automatic separation device. Free fall metal detector has a small pipeline, it has higher detection accuracy than conveyor metal detector.

Wet products relative to dry products are more difficult to detect, wet products contain water,  one of the characteristics of water is conductive. The packaged wet products also contain salt, sugar, they can also influence detecting. We call this phenomenon product effect. So if your company produce wet products, you should choose waterproof and anti-influence one when you buy metal detector. However, there is another wet product that is liquid, paste product. These products should be detected be pipeline metal detector. Using pump to offer pressure to put the products through the pipe. When detecting pure liquid products, the pressure parameter should be set, because the speed of inspection should be the same as that of the detector. When the product of slurry and paste is checked, if the bubbles are formed in the product, it is difficult to distinguish the detector, and it is prone to false alarm.

The above is to separate the dry and wet products, but there are some common characteristics. For example: temperature, testing environment, etc. So how to reduce these product effects, it is necessary to choose a suitable machine to use understand how to correctly avoid product effects.
