In recent years, a large pork processing enterprise has mainly produced frozen pork, ham, pork legs and other products. Due to the increasingly strict international food safety regulations, customers need to strengthen the foreign object detection process in the production process, especially the screening of metal impurities (such as metal fragments, broken needles, machine parts, etc.). To ensure that the product meets the standards, the customer has introduced Fanchi Tech metal detection machines, which are deployed at the end of the production line before the packaging process.
Application scenarios
Detection target
Product type: Whole piece pork, segmented pork leg, sliced ham.
Potential metal foreign objects: metal debris from equipment maintenance residues, broken cutting tools, etc.
Equipment deployment
Installation location: at the end of the production line, immediately after weighing
Conveyor speed: adjustable to 20 meters per minute to accommodate different product flow rates.
Detection sensitivity: Iron ≥ 0.8mm, non-ferrous metals (such as stainless steel) ≥ 1.2mm (in accordance with EU EC/1935 standard).
Operation process
Loading materials
The workers evenly place the pork/pork leg to be inspected on the conveyor belt to avoid stacking.
The device automatically recognizes the product and displays the conveyor belt speed, detection count, and alarm status in real-time on the display screen.
Detection and sorting
When the metal detector detects a foreign object:
The red light on the display screen flashes and emits a buzzing alarm.
Automatically trigger the pneumatic push rod to remove contaminated products to the 'non-conforming product area'.
The products that have not been alarmed will continue to be transported to the packaging stage.
Data recording
The device automatically generates detection reports, including detection quantity, alarm frequency, and foreign object location estimation. The data can be exported for compliance auditing.
Results and Value
Efficiency improvement: The daily detection volume of pork products reaches 8 tons, with a false alarm rate of less than 0.1%, avoiding the risk of missed inspections caused by manual sampling.
Risk control: Three metal contamination incidents (all involving stainless steel debris) were intercepted in the first month of operation to avoid potential recall losses and brand reputation risks.
Compliance: Successfully passed the surprise review by the European Food Safety Authority (EFSA), and the customer's product export qualification was renewed.
Customer feedback
Fanchi Tech's metal detector has an intuitive operation interface and low maintenance costs, solving the pain points of automated detection on our production line. In particular, the function of penetrating foam box detection ensures the safety of the final packaged products. "—— Customer Production Manager
Summary
By deploying Fanchi Tech metal detection machines, the company has achieved full chain metal foreign object control from raw materials to finished products, ensuring consumer safety and enhancing trust in the international market. In the future, we plan to promote similar equipment in more factories to further strengthen our foreign object detection capabilities.
