What Makes a Centrifuge ‘Food-Grade’? Materials, Design, & Certification

When it comes to processing materials in the food industry, safety, hygiene, and efficiency are non-negotiable. This is where a Food Centrifuge Machine plays a vital role—ensuring reliable separation, purification, and clarification processes while meeting strict industry standards. But what truly qualifies a centrifuge as “food-grade”? At Reyes Machinery, we combine high-quality materials, precision engineering, and international certifications to offer trusted solutions for the food sector.

In this article, we’ll explore the core aspects that make a centrifuge food-grade and why we stand out as your best partner in this space.

1. Stainless Steel Components: The Gold Standard

One of the first indicators of a Food Centrifuge Machine being food-grade is the use of stainless steel components in areas that come in contact with the product. Stainless steel resists corrosion, does not react with food materials, and is easy to clean and sanitize.

All of our centrifuges—including tubular centrifuges, disc separators, and decanter centrifuges—feature contact parts made of high-quality stainless steel. This significantly reduces the risk of chemical contamination and ensures compatibility with both acidic and alkaline substances found in many food products. Whether you are processing virgin olive oil, coconut milk, or separating components in dairy production, stainless steel ensures hygiene is never compromised.

2. Mirror Polishing for Hygienic Finish

Surface finish matters greatly in food processing equipment. Rough or uneven surfaces can trap food particles, promoting bacterial growth and making cleaning difficult. That’s why mirror polishing—a technique that creates an ultra-smooth, reflective finish on stainless steel—is crucial.

We ensure that the internal surfaces of our Food Centrifuge Machines are mirror-polished, which helps prevent residue buildup and supports clean-in-place (CIP) protocols. This attention to detail ensures the centrifuge remains sanitary, extending its lifespan and maintaining product purity.

3. Compliance with CE and ISO Certifications

For a Food Centrifuge Machine to be accepted by global food safety standards, it must comply with recognized certifications. Each of our machines is manufactured under ISO9001:2015 quality management system certification and carries EU CE product certification.

These certifications reflect a commitment to safety, precision, and consistency. They confirm that our manufacturing processes and final products meet the regulatory standards required in food processing environments across more than 50 countries. When you choose us, you’re choosing peace of mind backed by globally recognized credentials.

4. Design for Efficient Food Oil and Water Separation

The design of a food-grade centrifuge must facilitate efficient and safe operation. Our Centrifugal Oil Water Separator units are designed to handle sensitive food materials like cold-pressed coconut oil, avocado oil, and dairy liquids with precision. They support the complete flow process from raw material to clarified product—whether it's through decanter centrifuges for large-scale separation or disc separators for finer filtration.

Each Centrifugal Oil Water Separator at Reyes Machinery is carefully tested through a strict commissioning and inspection process before leaving the factory. This guarantees stability, performance, and compliance with food-grade applications.

5. Trusted Across the Food Industry

Our centrifuges are widely utilized in food processing companies such as virgin olive oil production, clarification of coconut milk, and separation of milk and dairy. Our disc and tube equipment is particularly required to provide precise, high-speed separation in the production of food oils.

Due to our advanced imported manufacturing technology, we have gained the trust of global food manufacturers requiring consistent product quality, simplicity of operation, and good after-sales service.
