Why Should You Consider Using A Metal Detector In The Food Industry?
It is hazardous to have any metal contaminants in your food.
Furthermore, the smallest amount from worn-out equipment or unsafe operating conditions will compromise the food quality.
This leads to thousands of food items or stock worth thousands of dollars being recalled.
Besides, all this will damage your reputation, and consumers will trust you less.
Here are the main reasons you should always use a metal detector in the food industry:
The metal detector ensures the food you are making has no metal fragments.
Besides, quality assurance by using your eyes cannot locate these contaminants.
This means your food products will be safe for human consumption.
Metal detectors will save you several hours in quality assurance processes.
Also, automatic low-maintenance metal detectors minimize the time for manual quality checks.
This means you will be able to conduct quality assurance quickly and efficiently.
When the food items you make have a high metal contamination level, it may indicate problems with your equipment.
This means you can conduct preventative maintenance practices before your machinery completely breaks down.
Also, it will save you lots of money that you would experience if your machine faces downtime.
Customers must consume safe food at all times.
This means you are obliged to produce safe food for human consumption without fail.
At What Stage In The Production Does Metal Contamination Happen?
Metal contamination can occur at different stages in your production line, therefore, you need to be keen at all times.
Contamination can occur at the following stages within the production cycle:
- In the field
- During food processing
- During packaging processes
How Does A Metal Detector Operate?
Metal detectors have evolved from the traditional coils wound on non-metallic frames connected to radio frequency receivers and transmitters.
The emergence of X-ray inspection is proving to be successful to find several sized contaminants.
However, metal detectors are still suitable for specifically identifying metal fragments rather than other types of contaminants.
Metal detectors will look for signal interference.
This means that non-conductive products are suitable for use with metal detectors.
When a metal is within a dry non-conductive substance like pasta, the metal detector can easily locate it.
In such suitable conditions, the metal detectors can easily detect and eliminate small metal fragments that the human eye cannot see.
This is because it is sensitive enough to recognize interference from such contaminants.
What Types Of Metal Contaminants Can Be Found In Food?
There are three versions of metal that a metal detector can remove from food items.
Besides, it is important to know such differences as it will determine which type of metal detector is suitable for your needs.
Such metal contaminants include the following:
These metals have a high iron content level.
Besides, they are conductive and magnetic thus the metal detector can easily sense and eliminate them.
These metals contain small amounts of iron.
Besides, non-ferrous metals are non-magnetic but are conductive, thus, the metal detector will easily detect and remove them.
This is a ferrous metal but has high levels of chromium.
Stainless steel is the most difficult metal to detect since it is not conductive or magnetic.
Furthermore, it is more difficult to identify if the product you are producing has high salt content or contains water.
However, you can install x-ray detection devices to assist in the detection and elimination of stainless steel.
When Should You Use A Metal Detector?
Also, you can use a metal detector at any phase in your production process.
Besides, using it at the end of the production line will increase the quality assurance of the items.
Also, it is more effective when you use it in the first step in the food production process when you are mixing the dry ingredients.
Using it at the first stage in the production line makes it cost-effective when locating contaminants.
This means you will lower waste and locate metal contaminants before you add other ingredients.
Manufacturers can employ HACCP units to evaluate their process and determine where the production contamination might happen.
For this reason, it is important to use the metal detector at all stages in the production line to ensure high-quality assurance.
When you use several ingredients and conduct a lot of production processes, it is advantageous to use the metal detector once you complete the process.
In such scenarios, manufacturers also include x-ray systems.
This is because using a lot of ingredients can increase the chances of contamination, which might be non-metallic.
What Detection And Inspection Issues May You Encounter While Using A Metal Detector?
Metal detectors can experience false triggers which can lead to wastage, profit loss, and slow production speeds.
Standard versions of metal detectors may struggle to repeatedly and accurately detect metals during production.
The reason for this is that various items emit different signals due to product effects such as fluctuating moisture content.
However, you can combat this issue by using multispectrum x-ray detectors.
Another issue is ensuring maximum efficiency while maintaining the robustness of the metal detector.
Besides, no producer wants to lower their production rate.
They need to balance their production requirements while ensuring food quality is of utmost importance.
Compliance with regulatory needs such as strict standards, legislations, etc., poses a challenge.
Another issue is operator safety as accidents can happen which is traumatic to their families.
This may lead to downtime and risks your reputation once the public gets wind of it.
Ensure the metal detector has safety systems like safety valves, guarded rollers, etc.
Also, ensure you correctly train your staff to handle the device as per the manufacturer’s recommendations.
How Will A Metal Detector Improve Quality Assurance In Your Application?
