The Food metal detector is mainly used to detect broken pins, wires, or various metals such as lead, copper, aluminum, tin stainless steel that are entrapped or lost in food, raw materials, or products, and is suitable for product detection with strong product effects and other industries with high requirements for detection sensitivity, interference resistance and waterproofing, including sauces, sausages, dumplings, hams, soups, confectionery, pickled foods, salted food, fast food, food additives, starch, glucose, tobacco, fresh meat, dairy products and many more. Next, we take a look at the role of Belt metal detectors in the food industry and the factors influencing their application. Here are some answers.

What is the role of metal detectors in the food industry?

The metal detector is mainly used as security screening equipment, but in the food industry, the metal detector also plays an important role, food metal detector is to prevent metal foreign objects from mixing into the food, it is in the different stages of food processing role are.

Firstly, in the raw material storage phase, the food metal detector can be used to detect metals mixed into the raw material and prevent foreign metals mixed into the raw material from damaging the production equipment and not affecting the subsequent processes. Secondly, the food metal detector is used during the production process to detect foreign metals mixed in with the process: screws and nuts from production equipment, tool fragments, metal dust from operations, rust, fragments of metal tools, staples, workers' jewelry, and sewing needles, etc. Thirdly, detection after monoblock packaging gives a high level of sensitivity. It should be noted that the industrial metal detector is used for aluminum plated packaging and aluminum foil packaging. Fourthly, final metal detection before shipment can reveal nuts or screws that may have been mixed in after the monoblock line.

Factors influencing the application of metal detectors in the food industry.

1. Characteristic categorization of the product being inspected

The metal detector is based on the measurement of electrical conductivity and magnetic fields to detect metals. Many of the products being inspected have one of these characteristics or both, for example, wet products are electrically conductive and can generate misleading signals; dry products, some of which have high iron content, can generate strong magnetic signals.

2. Metal detector sensitivity to different metals

Commonly there is mainly iron, non-iron and non-magnetic stainless steel, iron is easier to be detected, non-iron is second, while stainless steel is difficult to be detected by a metal detector.

3. The shape of the metal

Metal detection is standardized on a spherical shape, as the shape of any side of the sphere is the same. In practice, contaminants are rarely regular spheres and will produce different signals depending on their orientation when passing through the metal detector. The most obvious example of this is a wire-shaped contaminant: a wire-shaped metal passing through the detection port will produce very different signals depending on its metal type and the direction in which it is placed. In the worst case, it only produces a signal size equivalent to that produced by a sphere with a thick wire diameter.

4. Sensitivity of the metal detector

Theoretically, the sensitivity of a particular conveyor metal detector depends on the size of the detection port. The smaller the detection port, the smaller the metal can be detected. The smaller the dimension of the rectangular detector port, the more sensitive it is. The position of the detector when passing through the detector port is also relevant to sensitivity. The center line axis is the least sensitive point and it is here that the performance tests are done. This is because the closer the metal is to the detection edge or coil, the greater the signal generated and thus the easier it is to detect.
