Sanitary Rotary Airlock Valve

The Sanitary Rotary Airlock Valve is a core feeding and unloading device specifically designed for industries with stringent requirements for cleanliness and sterility, such as food, pharmaceuticals, and bioengineering. Leveraging the company's years of experience in bulk material handling technology, it is designed and manufactured in strict accordance with international hygiene standards such as GMP, FDA, and 3-A. Integrating core advantages such as a seamless structure, food-grade materials, and precision sealing, it completely eliminates material residue and cross-contamination, achieving "sterile conveying, cleanliness compliance, and stable reliability." Balancing conveying efficiency and hygiene compliance, it is a benchmark device for powder handling in high-cleanliness environments and is widely used in food, pharmaceuticals, health products, and fine chemicals.

As a key supporting equipment in the aseptic production process, this product focuses on three core functions: connecting the material storage and conveying systems, balancing hygiene compliance and production efficiency, and ensuring that the production line meets industry regulatory requirements and operates stably and efficiently.

Aseptic quantitative feeding and unloading : The optimized impeller structure with no dead angles can stably control the conveying flow of powdery and granular clean materials, realize uniform feeding and smooth unloading, and is compatible with pneumatic conveying systems and automatic batching systems to ensure the precision of production process, while avoiding material damage and residue, eliminating microbial growth from the source, and meeting the requirements of aseptic production.

Clean and pollution-free conveying : Based on the whole process hygienic design, there is no material accumulation or dead corner inside the equipment. With a precision sealing structure, it effectively blocks the entry of external air and impurities, prevents material contamination and cross-contamination, and avoids powder leakage, ensuring a clean workshop environment that meets the hygiene supervision standards of the food and pharmaceutical industries.

CIP/SIP compatibility : Supports online cleaning (CIP) and online sterilization (SIP), and can be adapted to 121℃/0.1MPa steam sterilization conditions. It can complete the comprehensive cleaning and sterilization without disassembling the equipment, which greatly improves cleaning efficiency, reduces manual intervention, avoids secondary pollution during the cleaning process, and adapts to the needs of continuous aseptic production.

1. All materials meet hygiene standards, are sterile and residue-free.

All parts in contact with materials are made of food-grade or pharmaceutical-grade stainless steel (SS316 and SS316L are optional, and Hastelloy material can be customized), with no harmful substances leaching out, and comply with hygiene standards such as FDA 21 CFR 177.2600 and EU 1935/2004; the inner surface of the equipment is precision mirror polished, with a polishing degree of Ra≤0.4μm, with no dead corners, no dents, and no weld seams to hide materials, making it difficult for materials to adhere, and completely eliminating material residue and bacterial growth, fully meeting the requirements of aseptic production from materials to processes.

2. Fully compliant with certifications, adaptable to stringent regulations.

The products fully comply with international hygiene standards such as GMP, FDA, and 3-A SSI, and can provide complete material reports (MTC), cleanliness test reports, and sterilization validation reports. They support quality traceability and meet the audit and regulatory requirements of the food and pharmaceutical industries. Some models are compatible with ATEX explosion-proof and SIL2/SIL3 functional safety standards and can be directly exported to Europe, America, Southeast Asia and other regions, meeting the stringent global hygiene regulatory requirements.

3. Precision sealing to prevent cross-contamination.

It uses food-grade PTFE and EPDM/FKM seals, combined with a triple dynamic sealing structure (main seal + secondary seal + emergency seal), to achieve ANSI Class VI zero leakage, effectively preventing powder leakage and the entry of external impurities, while avoiding cross-contamination between different batches of materials; the seals can withstand CIP cleaning fluid and SIP high-temperature steam, and will not age or fail after repeated cleaning, balancing sealing performance and hygiene safety.

4. Compatible with CIP/SIP, making cleaning and sterilization more convenient.

With an optimized, seamless flow channel design, online cleaning (CIP) and online sterilization (SIP) can be achieved without disassembling core components. It is compatible with automated cleaning and sterilization systems, can be linked with production lines, requires no manual intervention, significantly saves cleaning time, and avoids secondary contamination during disassembly. The equipment actuators have an IP67 protection rating, can withstand high-temperature and high-pressure rinsing, ensure thorough cleaning and sterilization, and are suitable for continuous aseptic production conditions.

5. Stable and durable, suitable for a variety of clean materials.

Designed to address the characteristics of clean materials, the contact parts are specially treated for anti-sticking and anti-corrosion properties, exhibiting excellent wear resistance, corrosion resistance, and anti-sticking performance. It does not chemically react with materials and does not contaminate them. The structure is compact and reasonable, with low vibration and noise during operation, allowing for long-term continuous aseptic operation and a low failure rate. The wear parts are standardized and made of sanitary-grade materials, making replacement convenient and reducing later maintenance costs and downtime losses.

Designed specifically for sterile, high-cleanliness production environments, it is widely used in industries with stringent hygiene standards, such as food, pharmaceuticals, health products, fine chemicals, cosmetics, and bioengineering. It is especially suitable for:
