What are the special requirements for the selection of steel ball materials in food processing equipment?

Update:17 Jun 2024

1. Food safety: Food safety is one of the primary considerations. As a component that contacts food, steel balls must comply with strict food contact material regulations and standards, such as the requirements of the US FDA (Food and Drug Administration) or the EU Food Contact Material Directive. The selected steel ball material must be non-toxic and harmless, and must not release harmful substances or affect the quality and safety of food. Common food contact safety materials include stainless steel (such as 304, 316L, etc.), which have good chemical stability and corrosion resistance and are suitable for contact with all kinds of food.

2. Corrosion resistance: Food processing equipment usually needs to withstand high humidity, high temperature or strong acid and alkaline environments. Therefore, the material of the steel ball must have excellent corrosion resistance, be able to work stably for a long time under these harsh working conditions, and will not release harmful substances to contaminate food due to corrosion. Selecting stainless steel materials with strong corrosion resistance can effectively reduce the risk of material surface damage and material performance degradation caused by corrosion, and ensure the long-term and reliable operation of the equipment.

3. Mechanical properties: Steel balls are usually used to transmit power or realize motion transmission in food processing equipment, so they need to have good mechanical properties. This includes sufficient strength, wear resistance and fatigue resistance to ensure that no damage or failure occurs under long-term and high-frequency working conditions. Choose steel balls made of high-quality steel, such as 304 stainless steel balls or 316L stainless steel balls, which have good mechanical strength and wear resistance, can withstand high loads and frequent movements in food processing equipment, and ensure the stability and reliability of the equipment.

4. Surface finish:
The surface finish of steel balls is crucial to the hygiene standards of food processing equipment. The smooth surface can reduce the growth of microorganisms and dirt, facilitate the cleaning and disinfection of equipment, and thus ensure the safety and hygiene of food. Choose steel balls with specially treated or polished surfaces to ensure that their surfaces are smooth and free of defects, meet the hygiene requirements of the food industry, and reduce food quality problems that may be caused by surface roughness.

5. Temperature adaptability:
The steel balls in food processing equipment may work in high or low temperature environments, so the steel ball material must have good temperature adaptability. The selected material should be able to maintain stable physical and chemical properties over a wide temperature range, and will not cause significant changes or failures in material properties due to temperature changes. Stainless steel materials usually have a wide temperature adaptability and can meet the various working conditions of food processing equipment, ensuring the long-term and reliable operation of the equipment.
