Products Description
Need a safe, mobile, and GMP-compliant solution for intermediate material storage?
Guanjiang’s Stainless Steel IBC Silo (Intermediate Bulk Container) is engineered for closed, dust-free material transfer in pharmaceutical, food, and chemical production lines. Featuring Ra≤0.2μm ultra-smooth inner surface, silicone-sealed valves, and specialized casters, it eliminates cross-contamination and supports batch traceability — fully compliant with global GMP standards.
Key Advantages of Guanjiang IBC Silo
Inner surface polished to Ra≤0.2μm, outer to Ra≤0.8μm. Arc corners, no dead ends, no material residue — ideal for pharma and food production.
Hopper cover and butterfly valve equipped with silicone sealing rings. Ensures closed, safe, moisture-proof storage. Prevents dust cross-contamination.
Specialized casters protect cleanroom floors. Functions as intermediate storage, system buffer, and balanced operation for continuous production lines.
Made from 304/316L stainless steel. Double-sided TIG welding with groove preparation. Welding quality complies with JB4708 and JB4709. No deformation.

Frequently Asked Questions About IBC Silos
Q: What is the difference between Standard IBC Silo and Mixing IBC Silo?
A: Standard IBC silo (LDF series) is square with a conical bottom, optimized for storage and discharge. Mixing IBC silo (LDF-M series) has a different aspect ratio and is designed to fit into V-blenders or double-cone mixers for direct blending operations without material transfer.
Q: How do you ensure the sealing performance for potent pharmaceutical compounds?
A: Both the hopper cover and butterfly valve are equipped with silicone sealing rings (FDA-grade). For higher containment needs (OEB 3-5), we can provide additional gaskets, split butterfly valves, or fully contained transfer systems. Please specify your OEB level when inquiring.
Q: Are the casters suitable for cleanroom floors? Will they leave marks?
A: Yes. Our IBC silos come with specially made polyurethane casters that protect epoxy and vinyl cleanroom floors. They are non-marking, anti-static, and have low rolling resistance for easy maneuverability even with full loads.
Q: What surface roughness can you achieve, and how is it measured?
A: We achieve inner surface Ra≤0.2μm and outer surface Ra≤0.8μm through mechanical polishing and electropolishing. Roughness is verified using a contact profilometer, and inspection reports are provided with each IBC silo.
