よくある質問
How often should I calibrate my food metal detector?
It is recommended to calibrate your food metal detector daily before starting production. Additionally, a more thorough calibration should be performed monthly or quarterly, depending on the manufacturer’s recommendations and the frequency of use.
What type of cleaning solution should I use to clean my food metal detector?
Always use a food-grade cleaning solution when cleaning your food metal detector, especially when cleaning the conveyor belt and detector head. Avoid using harsh chemicals or abrasive cleaning agents, as these can damage the detector’s components and contaminate your food products.
How often should I replace the conveyor belt on my food metal detector?
The lifespan of a conveyor belt depends on factors such as usage frequency, product type, and proper maintenance. Inspect the conveyor belt weekly for signs of wear or damage and replace it immediately if any issues are found. As a general guideline, conveyor belts should be replaced every 1-2 years, depending on usage.
What should I do if my food metal detector detects a metal contaminant in a food product?
If your food metal detector detects a metal contaminant in a food product, follow your company’s established recall procedures immediately. This typically involves isolating the contaminated product, identifying the source of contamination, and removing any affected products from the production line. After addressing the issue, perform a thorough inspection and cleaning of the metal detector before resuming production.
How can I improve the sensitivity of my food metal detector?
To improve the sensitivity of your food metal detector, follow these tips:
- Regularly clean and calibrate the metal detector according to the manufacturer’s instructions
- Ensure the detector head and coils are free from build-up, dust, and other contaminants
- Adjust the sensitivity settings on the control panel gradually and perform sensitivity tests after each adjustment
- Replace worn or damaged parts, such as the detector head or coils, as needed
