Strategies for Maintaining Product Purity During Food Processing

For maximum extraction results in magnetic separation, the right equipment, at the right strength, must be chosen for a particular application. Equipment should be chosen based on the types of material being processed, how the material is introduced to the magnetic separator (i.e., flood vs. metered feed), and other environmental factors.

Proper metal detector selection depends at least as much on the product and the process as on the metal to be detected. Sometimes the existing form of the product—or, more frequently the process—leads to a very difficult, expensive, or “impossible” metal detection problem. Consult with an expert to select the most effective metal detector. Many suppliers offer free plant audits to help users identify the appropriate metal detector for their particular application and space constraints.

X-ray systems are being used everywhere, from the smallest operations to the largest corporations. Some major retailers are now encouraging or even requiring their suppliers to utilize X-ray systems. To determine whether or not an X-ray system is right for your application, you must first understand the technology’s capabilities and limitations.

To decide if X-ray technology is right for you, consider product testing, which some manufacturers offer at no charge. Testing is the best way to adequately evaluate all the variables involved in your particular application. By supplying the X-ray manufacturer with samples of your products, you can find out what the machines can actually do for you. Most importantly, find a manufacturer you trust. Your manufacturer should work with you to find a unit that meets your needs effectively, without the extra expense of unnecessary features.

The manufacturer you choose should help determine what products are right for you, now and in the future. The company should also keep you up to date on emerging technologies and support you with continued customer service.
