How can metal detectors perform more accurate detection?

For products in many industries, the accuracy of CE approved x ray device factory has an important impact on quality assurance, but the accuracy of metal detector equipment is affected by many factors.

How can metal detectors perform more accurate?

1

First, change the frequency

Since the product benefits generated by digital fluoroscopy x ray machine manufacturer are not the same, if the same frequency is used for inspection at this time, it will easily cause detection errors. Therefore, for some products such as meat, cheese, and seafood, the equipment frequency must be adjusted accordingly for detection, otherwise the equipment is prone to false alarms and targeted adjustments based on different product characteristics can bring more accurate detection!

Second, multi-frequency feature recognition

Nuoding’s metal detectors are currently equipped with a variety of fluoroscopy x-ray device supplier. Using two or more frequencies can achieve a certain effect and improve the detection sensitivity of metals. This method is a compromise solution, but for stainless steel the detection improvement is limited!

Understanding of characteristics

You can also use the device’s feature recognition function for product effects, and use intelligent identification methods to distinguish the difference between metal and product effects. Improving the working function of metal detectors can generally achieve good detection functions, but the detection requirements for aluminum foil packaging products are special Customized, at present Nording can provide aluminum foil metal detector equipment!

The above are several methods for more accurate detection of digital radiography x-ray machine price. Of course, the detection accuracy has a great relationship with the detection equipment. Nording can currently provide high-precision metal detector equipment for different industries to escort product quality!

Accuracy of metal detection has a significant influence on quality assurance

The same as is for the rest

First, change the frequency

Since the benefits of 4kw x ray system company are not the same, if the same frequency is still used for inspection at this time, it is very easy to have detection errors.  Therefore, for some products such as meat, cheese and seafood, the frequency of the equipment should be adjusted accordingly for detection. Otherwise, the equipment is prone to false positives. Targeted adjustment should be made according to different product characteristics, which can bring more accurate detection!

Nording is currently able to provide high-precision metal detector equipment for different industries to protect the product quality!

Different Types of Food Pollutants

In fact, the most common cause of CE approved x-ray system manufacturer is biological pollution (microorganisms and toxic substances), which mainly affects fresh foods, such as nuts and vegetables.  There are many reasons for this type of pollution, including manufacturers’ use of contaminated water and unsanitary food processing practices throughout the supply chain.  It is also one of the main reasons for the product recall that there is no declaration on the label of allergy products such as nuts or dairy products.  These may be components of the product, or they may be cross-contamination formed by residues from mechanical processing or previous product processing procedures.  There is no equipment to help food manufacturers detect biological contamination. The best way to avoid such accidents is to implement a strong health program.

Foreign bodies are the double column digital x-ray machine factory of food contamination in Britain and the third most common cause in the United States.  Foreign matter includes many different substances, including metal, plastic, glass and wood from production lines or packaging lines.  Just because there are many kinds of foreign bodies, the nature of food pollution accidents is very different.

For example, a well-known U.S. meat supplier recently had to recall thousands of pounds of ground beef for fear that it might have contaminated blue thread ends.  It was found that this was because the cotton/polyester fiber mixture adhered to a production machine during routine cleaning.  The company believes that some of these silk threads eventually entered the finished products and were all distributed to warehouses throughout the United States.

In another well-known accident, a leading supplier of bread products in the United States voluntarily destroyed some well-known brand products, fearing that these products had contaminated glass fragments from a broken bulb in its baking equipment.  The company announced the recall after receiving three consumer reports that small pieces of glass were found outside the bread.  Although no injuries were reported, the accident was widely spread in many media channels.

Many similar incidents have taken place in Europe. fluoroscopy x-ray system supplier recalled some meat and vegetable pie products from large chain retail stores such as Asda and Lidl7 for fear of glass debris contamination.

Select the best technology for your application

Broadly speaking, there are two mainstream physical contaminant detection technologies-metal detectors and X-ray foreign matter detectors.  x-ray unit for cancer hospital manufacturer are applied by food manufacturers and processors to the critical control point (CCP) of many production processes. These processes determine the risk of pollution through risk analysis and critical control point (HACCP) audits.

Modern metal detector systems can identify all metals in food, non-food and drugs, including ferrous metals (chromium, steel, etc.), non-ferrous metals (copper, aluminum, etc.), and magnetic and non-magnetic stainless steels.  The X-ray foreign body detector system can also detect metal and nonmetal pollutants, such as glass, ore, calcified bone, high-density plastic and rubber compounds.  These detection systems can be installed at CCP to detect foreign raw materials before processing.  These systems can also be installed at the middle or end point of the production line or packaging line.

Although metal detectors and X-ray foreign body detectors can provide various functions 9, their pollution detection methods are not foolproof.  There are usually some areas of overlap between the two technologies, and careful consideration must be given to which is best suited to the application and budget at hand.  For example, metal detection is considered the most appropriate technology for aluminum contamination in non-metallic packaging.  Aluminum is a light metal and a good electrical conductor.  Because its ray absorptivity is lower than that of other metals (such as iron and stainless steel), it will lead to a decrease in sensitivity in the X-ray foreign matter detector system.  In other words, the size of aluminum contamination needs to be twice that of metal and stainless steel in order to achieve equivalent detection results.  On the other hand, due to the excellent conductivity of aluminum, metal detector technology can usually be used to detect smaller sizes, so the latter is usually a better solution.

However, when testing the metal contamination in aluminum foil packaging, the choice is inclined to the other side.  Metal detectors are difficult to find contaminants in aluminum foil packaging.  However, due to the working mode of the X-ray system, the influence of aluminum packaging materials on the detection level can be ignored.  The X-ray foreign matter detector can directly see through the low-density foil paper to better detect the metal contaminants in the package, which will provide a better solution in this case.  The simplest way to choose metal detector or X-ray foreign body detector is to start from application.  The first step is to carry out hazard analysis and critical control point (HACCP) audit or hazard analysis and risk-based preventive control (HARPC) audit.  The detailed differences between HACCP and HARPC10 will be described separately, but basically, HARPC also includes aspects such as potential terrorist acts and/or vandalism and food fraud.

Such audits will help understand the requirements of 600mA DR x-ray device price related to compliance with GFSI and/or major retail groups in gfsi.  HACCP audit will determine the pollution risks introduced into the manufacturing process and the types of pollutants that may be encountered.  Critical Control Points (CCP) should be established to reduce risks, and product testing equipment should be installed at these points to reduce pollution risks to an acceptable level.  HARPC audits also cover pollution in the manufacturing process, but also consider other security, such as visitor access and control.  Suppliers and recall procedures are also more formal. HARPC system requires food factories to determine and implement prevention and control measures based on science or risks, rather than critical control points (CCP).

Whether HACCP or HARPC methods are used, appropriate technologies should be selected according to the pollution risks during production, which are the same.  If the audit determines that metal is the only pollutant that may be found, then metal detectors may be the best solution.  Similarly, if it is determined that other pollutants may be encountered, such as glass, stone or high-density plastic, the UC Arm digital x-ray system factory is more suitable.  In either case, product testing is recommended to establish the most appropriate technology.  In many cases, there is only one suitable solution: metal detector or X-ray foreign body detector system.  However, it may be necessary to install metal detectors and X-ray foreign matter detector systems on different CCP in the same food environment and the same production line at the same time.

Compared with the use details of X-ray foreign body detector, the main characteristics are described in detail

The X-ray foreign body detector mainly uses mammography x ray supplier, integrated photoelectric technology, integrated computer, digital signal processing and other technologies to distinguish, extract and distinguish image information through vision and pattern recognition. zui finally realizes the processing of foreign bodies or missing products mixed in food.

10. The X-ray foreign body detector adopts high-speed video Cam eraLink interface protocol, which enables the transmission speed of zui large image to reach 1.6Gbps, ensuring the system has good real-time performance in high-speed detection.  In addition, the use of radiography x-ray system company enhances the generality and expansibility of the detection system.
11. The functions of the X-ray camera, the drive of the X-ray linear array detector, the acquisition and transmission of image data, and the image preprocessing algorithm are all implemented on the single chip FPGA by adopting a highly integrated pure digital solution.  Zui greatly simplifies the structure of the system, improves the reliability of the system, reduces the failure rate of equipment, and is more reliable, stable and maintenance-biased.

Portable X-ray Machine Guarantees Passenger Safety

With the development of the times, DR x-ray unit price have begun to use high-tech means of transportation, such as subways.  In order to ensure the safety of these vehicles, we need to carry out strict X-ray examination.  Protect the privacy of passengers and staff, except under special circumstances.  Passengers should not open the package for inspection.

As the name implies, passengers can quickly determine whether they are carrying metal products through the door.  The alarm went off when the door touched the metal.  Then, security personnel have the right to request passengers to conduct a detailed search.  Check and inspect to ensure the safe transportation of metal products.
We understand that the troubles of digital radiography x ray device price are constantly updated and upgraded, and the troubles of high sensitivity and fast response will not impose any workload on safety and impact.  Most of the time, the security personnel can find the metal tableware from the passengers when the security door reminds them.
Therefore, many public places rely on safety gates for safety inspection, which is safe and reliable.  Therefore, safety has become an important part of public transportation.  In order to ensure the safety of public transportation, safe use has become necessary.  At present, many cities in China use foreign advanced technology to manage access control, and then complete production in China.
With the increase of China’s national security, UC Arm digital x ray unit company will start new troubles, independently develop and realize the influence of technology and localization of production as soon as possible.  Safety gates have become safety devices for subway transportation to ensure the safety of passengers.  Manufacturers of portable X-ray machines have been working hard.

How can the danger of physical pollutants in food be prevented?

In the field of food safety, physical pollutants are the first and most important problem.  If metal, bone, plastic, glass fragments or any other foreign matter are allowed to enter the food supply chain, serious damage may result.  This is a major consideration for food manufacturers and X C Arm x-ray system supplier as they strive to ensure that pollution does not occur.

This is not just a matter of consumer health protection.  Product recall due to physical pollution is also a great reputation risk.  Food safety incidents will make national and international headlines. A widely spread accident may destroy a brand in a very short time.  In addition, there are more specific financial impacts: product recalls caused by physical pollution may cost tens of millions of yuan. If the company is found to have violated health and safety regulations, it may face huge fines.  In a word, physical pollution in food must be avoided at all costs.  However, we are still surprised to see that the pollution situation is continuously increasing.  Swiss Re’s report Globalized Food Safety1 shows that the number of products recalled in the United States in 2015 and the costs associated with these recalls have almost doubled since 2002.

More than half of the food recalls in the United States cost more than $10 million.  Some companies have lost more than $100 million in direct costs.  Moreover, according to a latest food recall strategy report released by Emerald Insight2, recalls usually trigger interlocking effects of the entire supply chain and industry ecology.  The situation is similar in other major markets.  Reports from the Food Standards Agency (FSA) and the Scottish Food Standards Agency (FSS) show that food safety incidents caused by foreign body pollution in the UK in 2016/173 increased by 7% compared with the previous year.

The increase in the frequency of such food safety incidents may be attributed to several main factors, in addition to a longer supply chain, a longer and more complex food production environment and more reporting methods.  Obviously, the increase in the number of such accidents is definitely a trend that double column digital x ray system company and processors have to reverse.

How can the danger of physical pollutants in food be prevented?

With the continuous improvement of living standards, the quality and safety of people’s food and daily use of industrial products also have higher requirements, and the state has correspondingly formulated strict safety inspection regulations and laws.  In order to better meet the relevant requirements and improve the detection level, the X-ray foreign body detector has also developed from the original single-view detection technology to a new multi-view detection technology, so as to provide more choices for customers with different needs.

With the penetration ability of X-ray foreign body detector, hard foreign bodies such as bones, plastics and various metal foreign bodies can be detected with higher sensitivity and stability, helping you to improve the quality of finished products more effectively.  Not only can foreign matters in foods (such as various meat products, aquatic products, fruits and vegetables, additives, milk powder, chocolate, etc.) be detected, including metals, glass, ceramics, stones, bones, plastics, etc.;  Can also identify product defects, such as packaging cracks, bubbles, content defects, etc.;  Complete finished 30kw mobile x-ray device factory is realized.  X-ray foreign body detector is widely used in food industry.  The pharmaceutical industry;  Textile industry, integrated circuit board and other industrial industries.  Quality control in the food industry meets HACCP and IFS requirements to identify product defects, such as product breakage, product deformation or product missing, and eliminate potential product quality hazards.

Detection Technology and Preventive Measures of Physical Pollutants

Fortunately, the development of product inspection technology has enabled UC ARM DR 50kw x-ray machine company to be detected now.  In a fast moving production line, metal, glass, high density plastic, ore, calcified bone and rubber contaminants can be easily found using equipment such as metal detectors and X-ray foreign body detector detection systems.  The accuracy of such equipment will be affected by many factors.  These factors may include the size and location of the contaminant, the density of the contaminant relative to the product to be tested, and the type of product packaging material used.

The type of food itself is also an important factor.  In many food production processes, raw materials arrive in liquid, pasty and pasty forms, and are mixed and blended after being pumped through a pipeline system.  There are many advantages in detecting pollutants in such foreign raw materials early in the 4kw x-ray device supplier.  Liquid, paste and paste are usually more homogeneous and easier to detect.  Pollutants are also larger and easier to find.  Early detection will also protect expensive processing equipment from further damage downstream;  And will eliminate pollutants before adding other production values, minimizing waste.

When detecting the pollution in unpackaged bulk materials and loose granular products, both the detection technology installed on the horizontal conveyor and the detection technology located at the gravity drop of products before processing or packaging are efficient ways to remove pollutants.  Typical bulk products that can use such detection methods include sugar, flour, grains, corn and beans;  Dehydrated fruits, nuts and vegetables;  Snacks and candy;  Meat, poultry, fish and seafood.  After processing and packaging are completed, the final product inspection at the end of the production line is the last line of defense to detect any foreign matter contamination before the product is transported to retailers and supermarkets.  In this environment, the type of 400mA DR x-ray machine factory and the type of potential pollution determine the type of product inspection system that should be used.

Different Types of Food Pollutants

In fact, the most common cause of food recall is X 200mA DR x ray system factory (microorganisms and toxic substances), which mainly affects fresh foods, such as nuts and vegetables. There are many reasons for this type of pollution, including manufacturers’ use of contaminated water and unsanitary food processing practices throughout the supply chain. It is also one of the main reasons for the product recall that there is no declaration on the label of allergy products such as nuts or dairy products. These may be components of the product, or they may be cross-contamination formed by residues from mechanical processing or previous product processing procedures. There is no equipment to help food manufacturers detect biological contamination. The best way to avoid such accidents is to implement a strong health program.

Foreign bodies are the second most common cause of food contamination in Britain and the third most common cause in the United States. Foreign matter includes many different substances, including metal, plastic, glass and wood from production lines or packaging lines. Just because there are many kinds of foreign bodies, the nature of food pollution accidents is very different.

For example, a well-known U.S. meat supplier recently had to recall thousands of digital radiography x-ray system manufacturer for fear that it might have contaminated blue thread ends. It was found that this was because the cotton/polyester fiber mixture adhered to a production machine during routine cleaning. The company believes that some of these silk threads eventually entered the finished products and were all distributed to warehouses throughout the United States.

In another well-known accident, 500mA DR x ray system manufacturer of bread products in the United States voluntarily destroyed some well-known brand products, fearing that these products had contaminated glass fragments from a broken bulb in its baking equipment. The company announced the recall after receiving three consumer reports that small pieces of glass were found outside the bread. Although no injuries were reported, the accident was widely spread in many media channels.

Many similar incidents have taken place in Europe. A British bakery supplier recalled some meat and vegetable pie products from large chain retail stores such as Asda and Lidl7 due to concerns about glass debris contamination.

Pay attention to the use of food X-ray machine

Food X-ray machine, also known as RF machine x-ray unit factory, or X-ray foreign body detector. It generates X-rays through equipment, and uses X-ray penetrability to detect metallic foreign bodies mixed in products and nonmetallic foreign bodies with high density. In addition, the food X-ray machine can also carry out product defect detection, package damage detection and weight detection. Widely used in food, medicine, textile, integrated circuit board and other industries. Quality control in the food industry meets HACCP and IFS requirements, identifies product defects such as product damage, product deformation or product loss, and eliminates product quality risks. Principle of Food X-ray Machine: It mainly uses the penetration of X-ray, the collection of photoelectric technology, the integration of computer, digital signal processing and other technologies to distinguish, extract and distinguish image information through vision and pattern recognition, and finally zui realizes foreign body processing.
Not only can foreign matters in foods (such as various meat products, aquatic products, fruits and vegetables, additives, milk powder, chocolate, etc.) be detected, including metals, glass, ceramics, stones, bones, plastics, etc.; Can also identify product defects, such as packaging cracks, bubbles, content defects, etc.; Complete finished product inspection is realized.
