The future development trend of food foreign body detection machine

With the gradual improvement of global food safety and export food hygiene and quality requirements, food processing companies are also striving to improve the level of detection of foreign materials while strengthening health management. This has, to a certain extent, promoted the detection of food foreign materials. Growing.

Traditional integrated metal detector

The earliest giant magnet placed above the food conveyor was the prototype of the metal detector. When the metal foreign matter in the product was absorbed by the magnet when the product flowed on the conveyor belt, its limitation was only Can detect magnetic metal itself. Therefore, the more perfect metal detection machine is well utilized with the improvement of detection requirements. Its main test object is metal, and the metal is roughly divided into three types: ferromagnetic metal, non-ferrous metal and stainless steel. The ease of detection is determined by the magnetic conductivity and conductivity of the metal itself. If it is iron metal itself has a magnetic and good electrical conductivity, it is easily detected; if it is copper, lead, aluminum and other non-ferrous metal itself does not have a magnetic, but the conductivity is good, relatively speaking, relatively easy to be detected; There are many kinds of stainless steel products, some are magnetic and some have no magnetic properties, and their electrical conductivity is also different. The most commonly used stainless steel products in the food industry are 304 and 316 stainless steel products, so their minimum sensitivity is often used as the main detection range for metal detectors.

High-performance X-ray foreign body detector

In order to better implement high standards of hygiene and quality control, X-ray foreign body detectors, which have been widely used in medical and security inspections, have also begun to exert their excellent detection capabilities in the detection of foods.

Using the strong penetrating power of X-rays and the principle of being able to image, it not only detects fine metal particles or thin lines that metal detectors cannot detect, but also detects non-metal foreign objects that are not recognized by metal detectors ( Such as glass, stone, hard bone, hard plastic, rubber, etc., which to a large extent solve the user's product mixed with other non-metallic foreign matter annoyance, so that the user's product quality has been a new increase. Not only that, the current X-ray foreign body detector also uses a shielding function to detect various foreign materials in the metal canned products and use the defective product detection function to detect product damage or lack of, these features are all metal detectors Unprepared. In addition, in the inspection mode of the X-ray foreign body detector, the world's first genetic algorithm (Genetic Algorithm) technology applied to the X-ray image processing, foreign body detection more effective and more comprehensive, so that food is more secure and safer.

China's first intelligent foreign object detection machine

Suzhou Taiyi Detecting Equipment Co., Ltd. developed the first intelligent detection machine to be introduced to the market in China. This testing machine was the first in China to achieve full digitization of metal detection technology through the combination of a DSP (digital signal processor) and a microcontroller. And intelligent; adopting new technologies and methods such as phase adjustment to solve the “product effects” and other problems that are not solved by metal detectors in China.

Yi Hong Detector Equipment Co., Ltd. technician Yu Hong demonstrated the function of this magical machine. He only saw him skillfully to open the machine, select the type of product test, and then clicked and started to pass a bag of powder containing no foreign substances through the machine. . Then, he put a standard test block (metal, glass or ceramic) on top of the powdered milk, and when it passes through the machine, it immediately sounds an alarm and stops working. In addition, the children's oral liquids can be tested again and they can also correctly distinguish whether they contain foreign substances. In the presence of foreign objects in the product, a “red dot” is marked on the screen, which can help manufacturers easily find foreign objects in food and medicine.
