Quick-Clean Rotary Airlock Valve

The Hanyue Quick-Clean Rotary Airlock Valve is a high-efficiency integrated feeding, unloading, and cleaning device tailored for high hygiene requirements and multi-material switching conditions. Leveraging the company's years of experience in bulk material handling technology, it incorporates a core design for quick disassembly and convenient cleaning, overcoming the pain points of traditional rotary valve cleaning being cumbersome and time-consuming. It achieves "quick disassembly and cleaning, no residue, and easy maintenance," while also featuring excellent sealing, wide adaptability, and compliance with hygiene standards. It is widely used in industries with strict cleanliness requirements, such as food, pharmaceuticals, and fine chemicals, making it the preferred equipment for powder handling that balances efficiency and hygiene.

As a core piece of equipment for powder conveying in high-cleanliness environments, this product focuses on three core functions, balancing conveying efficiency and ease of cleaning, connecting storage and conveying processes, and ensuring the compliant and efficient operation of the production line:

Precise quantitative feeding and unloading : The optimized impeller structure can stably control the conveying flow of powdery and granular materials, achieve uniform feeding and smooth unloading, and is compatible with pneumatic conveying systems and automatic batching systems to ensure the precision of production processes, while avoiding material damage and residue, meeting the requirements of high cleanliness production.

Quick disassembly and cleaning : Adopting a modular quick-disassembly structure design, no complicated tools are required. The impeller, valve chamber and other core material contact components can be quickly disassembled to expose all corners inside the equipment, which is convenient for thorough cleaning, greatly shortens the cleaning time, solves the problem of cross-contamination when switching between multiple materials, and improves production efficiency.

High sealing and pollution prevention : Suitable for clean production conditions, it adopts a double precision sealing structure to effectively prevent powder leakage and external impurities from entering, avoiding material waste and workshop dust pollution, preventing cross-contamination, ensuring product purity, and meeting the hygiene standards of the food and pharmaceutical industries.

1. Quick disassembly and cleaning significantly reduces maintenance time.

The optimized quick-release structure design, with core components using snap-fit connections, allows for disassembly, cleaning, and assembly by a single person without the need for specialized tools. Cleaning time is reduced by more than 60% compared to traditional rotary valves. The valve chamber and impeller are designed without dead angles, and the smooth polished surface (polishing degree up to #400) can quickly remove material residues. It is suitable for switching between multiple types of materials, significantly improving production line turnover efficiency and reducing manual cleaning costs.

2. High cleanliness standards met, adaptable to stringent hygiene requirements.

All parts in contact with materials are made of food-grade or pharmaceutical-grade stainless steel (SS316 and SS316L are optional). The design is free of dead corners and material accumulation, and the surface is precision polished, making it difficult for materials to adhere. This effectively prevents bacterial growth and material residue, meets hygiene standards such as GMP and FDA, and is perfectly suited for industries with strict cleanliness requirements such as food, pharmaceuticals, and fine chemicals, ensuring product quality from the source.

3. Excellent sealing, preventing leakage and contamination.

Employing food-grade seals and a double-sealing structure, coupled with high-precision machining processes, it boasts excellent sealing performance, effectively preventing powder leakage and the entry of external air and impurities. This avoids dust pollution in the workshop and prevents cross-contamination between different batches of materials. At the same time, it can block pressure backflow in the pneumatic conveying system, ensuring the continuity and stability of conveying, and balancing cleanliness and efficiency.

4. Wear-resistant and corrosion-resistant, suitable for a variety of clean materials.

The parts in contact with materials are made of high-quality stainless steel that is corrosion-resistant and odorless. Special polishing and anti-sticking treatments are applied to clean powders with different properties (such as food powder, pharmaceutical powder, fine chemical powder, etc.). It has excellent wear resistance, corrosion resistance and anti-sticking properties, does not react chemically with materials, does not contaminate materials, and extends the service life of the equipment while reducing the cost of replacement and maintenance.

5. Compact structure and strong adaptability

With its compact design, small size, and minimal installation space, it can be flexibly installed in various locations such as under storage silos, at the inlet of conveying pipelines, and next to batching machines. Its standardized interface design allows for seamless integration with existing pneumatic conveying systems, storage equipment, and metering equipment without complex modifications, making it suitable for various clean production conditions while balancing flexibility and practicality.

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

• Food industry: conveying, switching, and cleaning processes for materials such as flour, starch, milk powder, cocoa powder, and seasoning powder;
• Pharmaceutical industry: The feeding and unloading of clean materials such as pharmaceutical powders and health product raw material powders shall comply with GMP hygiene requirements;
• Fine chemical industry: Material handling processes for fine chemical powders, additive powders, etc., where cross-contamination must be avoided;
• Production lines that require frequent cleaning and rapid material switching in scenarios involving multiple varieties and small batches of production.
