Metal detector is an indispensable component in food processing production line

Metal detector is an indispensable component in food processing production line

Issue Time:2020-10-27

The metal detectors machine has now become a major part of many food processing lines in the world. However, how many times have we wondered: what is inside this stainless steel case, how exactly does the metal detectors machine work, and what problems will occur during the production process?

In order to obtain the ideal detection effect of the metal detectors machine, choosing the correct location for it is as important as choosing the machine as much as possible. Although it is often considered to be equipped with a metal detection system when planning to install a new production line, the existing production line requires metal detectors machine to be easily installed in the original production line.

Most food and drug manufacturers install metal detectors machines at the end of the production line to inspect the goods before they are delivered to retailers and customers. However, from cost considerations, earlier detection of contaminants is more valuable, because only low-priced ingredients are wasted, not packaged finished products. The ideal installation location of metal detection systems varies with products and industries, and varies from factory to factory. For most manufacturers, if the metal detector is installed in a relatively forward-facing process in the production line, the limited space is often a problem. The structure of SYNDARmetal detectors machine factory's metal detectors is easy to dismantle and install, and it is lightweight, which can save production space to a large extent.


Liquid products, such as soup or pie filling, can be detected online by the Pipe metal detector. At that time, the pipeline connected to the processing equipment carries the product through the detector. The metal detector manufacturer should be able to provide accessories that connect the device to any processing equipment. The type of pipe required depends on the temperature, flow rate and product viscosity, but it must be made of non-metallic materials.

Many food manufacturers install metal detectors machine before heavy and vulnerable equipment, because this can protect downstream machinery from damage and avoid production interruption, which directly benefits economically. The detector can then act as a guard for vulnerable delivery pumps, rollers and valves, preventing them from being damaged by metal contaminants. For example, in the production of biscuits, the detector is usually installed before forming the dough into the forming drum. The engraved brass rollers and forming rollers are very valuable and easy to scratch. Metal impurities will cause more serious damage. Installing metal detectors before the forming rollers can protect them from the hard metals in the biscuits. This also ensures that the contaminants are not further crushed, making detection more difficult.

The important role of the metal detector is to provide reliable protection for the product through sensitive and reliable detection of harmful metal small debris. However, this protection can only be achieved when the contaminated product is reliably removed from the production process and the safe product is delivered to the customer. Therefore, the automatic rejection system is as important as the performance of the detector itself.

When contaminants are found, the detector will generate a rejection signal to drive the rejection device after an adjustable time delay. It ensures that the contaminated products are rejected into the reject box. The rejection devices are mostly pneumatic devices. In the conveyor belt system, they can be push plates, flap doors or simple air blow rejection. Some products may require parts of the conveyor belt to sag or tilt to separate contaminated products from good products. For example, in the production of biscuits, the product passes through a return belt with a recycling bin underneath. If a metal object is found, a whole row of biscuits is rejected to ensure complete product protection. On the other hand, for soup soup, a diverter valve is used to introduce pollutants into the second pipeline, so that contaminated products are eliminated without interrupting production.

Because the reject device adopts a fail-safe mode, and electronic sensors can be used to check that the contaminated product is indeed rejected into the reject box without entering the production line, so the safety of the product is greatly guaranteed.

    The difference between dynamic checkweigher and static checkweigher
    Checkweigher is a kind of automatic checkweighing equipment widely used in the production line of pharmaceutical, food, chemical and other industries. It can detect overweight and underweight unqualified products in the production line in real time online. The weighing methods of weighing equipment are divided into dynamic and static weighing methods. What is the difference between them, let's understand together below:
