Detecting Danger: Foreign Contaminant Prevention in Premix Manufacturing

Ensuring food safety is paramount in the animal food industry in order to maintain high quality standards and protect consumers from potential hazards. Mesh screeners, magnets, and metal detectors are three effective tools utilized by dsm-firmenich premix blending facilities to prevent contamination by foreign materials, thereby safeguarding the integrity and safety of our animal food products.

  • Mesh screeners, commonly known as sieves or sifters, are essential tools used to separate and classify premix during the manufacturing process. These devices consist of a mesh screen which has been stretched over a frame. They have been installed within the premix processing system after mixing completion, but prior to final packaging. These screeners allow premix particulate to pass through the mesh screen while retaining and separating materials larger than the mesh into an overflow receptacle. Utilizing an effective screening process helps prevent foreign objects from reaching the final product, reducing the risk of injury or illness to consumers.
  • Magnets play a vital role in food safety by capturing and removing metallic contaminants from raw materials during processing. Metallic foreign materials can pose a significant risk if they enter the manufacturing process, potentially increasing health risk for consumers or damage to equipment. Magnetic separators are commonly employed in animal food processing facilities to attract and remove metal particles from raw materials, ingredients, and finished products. These separators utilize powerful magnets to attract metal contaminants, ensuring they are effectively removed from the product stream. By eliminating metal materials, magnets help maintain product quality and safety, reducing the likelihood of product recalls or adverse health effects due to contamination.
  • Metal detectors are another set of sophisticated instruments designed to detect and reject foreign contaminants in finished dsm-firmenich premix products. These devices use electromagnetic fields to identify ferrous, non-ferrous and stainless-steel foreign objects that may be present within the packaged final product. If a foreign metal object is detected, an alarm will activate, and the packaged material is separated from the packaging process flow. This allows further inspection and risk assessment by Quality Management. Utilizing continuous metal detection monitoring of the finished product stream helps prevent the risk of contaminated products reaching consumers, thereby safeguarding animal health, and maintaining consumer confidence in the safety and quality of dsm-firmenich products.

In conclusion, mesh screeners, magnets, and metal detectors are indispensable tools utilized by dsm-firmenich premix blending facilities in the quest to ensure food safety. These technologies work in tandem to screen, capture, and detect foreign objects and contaminants, thereby minimizing the risk of contamination and protecting consumers from harm. By implementing these robust food safety measures and employing advanced detection and removal technologies, dsm-firmenich can uphold the highest standards of quality and safety.
