Why use food metal detector?
Source of raw materials, has fish hook, metal dust，while cutting, cleaning, breaking processing may have shedding metal.
Packaging cable tie etc. so there has may way got the foreign metal inside of the food.
in order to compliant with FDA/HACCP/ISO standards, avoid hefty fines, product recalls, and claims.
it is neccessary to use metal detector for quality control.
What is a food metal detector?
The principle usually is balance coil, (electric induction), any metal pass the detector probe will cause an induced current.
Shanghai Juzhao Intelligent equipment Co., Ltd is a factory specializing in the production of food metal testing equipment, these equipment is mainly used in food production, processing, packaging and other aspects of the detection and removal of metal foreign bodies to ensure the safety and quality of food. With the promotion of food safety awareness and the continuous progress of technology, food metal detection plants are playing an increasingly important role in the food industry.
How to choice the best food metal detector?
Application scenario:
Determine which food types (such as baked goods, aquatic products, frozen foods, etc.) and the production line environment your food metal detector will be used for.
Performance requirements:According to the production demand, the required detection accuracy, sensitivity, anti-interference ability, operation convenience and other performance indicators are defined.
Normally, factory are willing to do sample test and give report.
note: different product different sensitivity. depends on detector probe size and electrical conductivity.
Describe product packaging material, size, weight, product line details.
Select the right supplier products according to budget.
Food metal detector false alarm? (solutions for common situations, basic problem maintenance.)
1.Check the working environment first.
***if have two metal detector machine, keep an distance 2-5meters. And frequency should be different.
2.Above no problem, check conveyor belt. Whether periodic false alarm without product on it.
(Metal detectors usually require regular maintenance, that is, cleaning the front and back of the belt).
*** can let your engineer stop motor, and let machine detecting,
No false alarm-it is the conveyor belt problem, need to clean or change.
Still false alarm-it is detector problem. (mainly is the PCB, eg: collection board, processing board etc.)
Clean the belt https://youtu.be/DLsHBR3ZEqc , if difficult there need to take out of the machine.
