goudsmit Germany recently received a request from a chocolate producer for use in cakes, cookies, and yogurt. The chocolate is in the form of chips and granules and may contain fine metal fragments with a diameter of less than 1 mm. This is a common problem in chocolate production. We were asked whether it is possible to separate metal-containing fragments from the product stream without product loss.

  Chocolate production begins after cocoa beans are dried, stored, and purchased by chocolate ingredient factories, initiating the processing procedure. The process can be roughly divided into the following steps in sequence: roasting, crushing, blending and grinding, refining, deacidification, and tempering and molding. After the cocoa beans are crushed, the cocoa butter (Cocoa butter) inside the kernels flows out as a thick slurry, which is often used for medical and cosmetic purposes; the remaining cocoa residue is then rolled to become cocoa mass, the raw material for chocolate. Through blending and grinding, chocolate begins to differentiate into varieties such as dark and milk chocolate. And inchocolatethe production process, it maycontain fine metal fragments with a diameter of less than 1 mm. Regarding how to separate and remove metal fragments from the product stream without product loss,chocolate producers have raised this question to us.

  To achieve this goal, Germany goudsmit has specifically developed high-gradient separators   with strong magnetic conveyor rollers for the food industry. With this system, we achieve extremely high separation efficiency not only for ferrous particles but also for weakly magnetic stainless steel particles (such as AISI 304 and AISI 316). High-gradient separators are more effective than free-fall magnetic separators because the latter must first slow down the metal particles before capturing them. In addition to chocolate, magnetic separators are also suitable for other dry, granular products, such as herbs and spices. The process itself is simple. A vibrating chute feeds chocolate chips and granules onto a conveyor belt, distributing the product in a single layer. The conveyor belt rotates the magnetic roller, which captures and removes metal-contaminated product. The clean product falls directly into the packaging machine. Hygiene is crucial, especially in the food industry. This is a consideration that goudsmit carefully addressed when designing the magnetic separator. The quick-release system makes disassembly and replacement of the conveyor belt fast and easy. The special open structure and easily liftable cover make the system easy to clean. Until now, most suppliers have focused on magnetic field strength, gauss, or tesla flux density. Years of experience at Germany goudsmit show that this does not guarantee good metal separation. For ferrous particles, we optimized the magnetic bar system to obtain the most effective bar diameter, magnet quality, pole thickness, and distance between bars. For example, we know that some stainless steel particles can already be captured with an air gap of approximately 11 mm, but the effect is better if these particles are in contact with the magnetic bars. For instance, AISI316L particles can only be captured when they are in actual contact with the magnetic bars.

  Germany Goudsmit is an international industrial company dedicated to the design and manufacture of magnets and magnetic systems for metal separation, recycling, transport, lifting, fixing, and demagnetization across various industries. Goudsmit magnetic separators remove unwanted metal parts, such as iron, as well as stainless steel AISI304 and AISI316. goudsmit magnetic separators separate unwanted metal particles and metal parts that may eventually be present in baby food, juice, frozen or canned vegetables, herbs, spices, flour, seasonings, cereals, milk powder, sugar, or chocolate during the production process. Goudsmit has been committed to researching the efficacy of various magnet systems, utilizing advanced 3D calculation software and a powerful test center. Separation yield is very important for quality assurance managers. Goudsmit product developers enjoy collaborating with them to further improve our magnet systems and separation yield. The food and chemical designs of Germany Goudsmit are based on these EHEDG standards, and Goudsmit was one of the first magnet suppliers to join EHEDG.
