Vacuum Feeder

This advanced material handling system is designed to meet the stringent demands of pharmaceutical, nutraceutical, and fine chemical industries, where maintaining product purity and ensuring compliance are paramount. The system boasts a fully sealed structure, keeping materials completely enclosed throughout the process, thereby achieving dust concentrations ≤3mg/m³, which satisfies the requirements for GMP Class D cleanrooms. This not only optimizes the working environment but also minimizes contamination risks.

Constructed with 316L stainless steel and PTFE inert materials, all contact parts are free from leachables and adsorption (adsorption rate ≤0.1%), meeting USP Class VI standards. This ensures that even highly sensitive Active Pharmaceutical Ingredients (APIs) remain uncontaminated during processing. Additionally, an optional inert gas protection system (nitrogen/argon) can be integrated to isolate oxygen-sensitive or moisture-prone materials, further safeguarding their stability.

The design incorporates flexible conveying pipes and low-pressure delivery, reducing the risk of particle breakage (breakage rate ≤0.5%) while ensuring uniform particle size distribution. Food-grade silicone rubber seals at pipe joints prevent any leakage, making it suitable for high-purity and sterile material transportation. An integrated central dust collection system achieves over 99% dust collection efficiency, ensuring emissions comply with environmental regulations.

In terms of process adaptability, the system supports various types of solid dosage forms, including powders (particle sizes 0.1μm-5mm), granules, crystals, micro-pills, and traditional Chinese medicine extracts. It can handle materials with challenging characteristics such as poor flowability, high viscosity, tendency to clump, and hygroscopicity. Customizable conveyance parameters include horizontal distances up to 60m, vertical heights up to 25m, and speeds ranging from 0.05 to 10m³/h, adapting to diverse facility layouts.

With PLC + touchscreen control, the system offers both manual and automatic modes, enabling unattended operation in automatic mode. Over 100 preset conveying recipes can be quickly accessed and modified, with support for storage, encryption, and traceability, preventing unauthorized access to process parameters. Real-time monitoring and remote control via mobile or desktop devices enhance management efficiency, while built-in fault diagnostics minimize downtime by automatically identifying issues like vacuum pump failures, pipeline blockages, and abnormal material levels.

Safety features include overload protection, anti-blockage protection, vacuum pump overheating protection, and emergency stop buttons. Optional explosion-proof designs (Ex tD A21/Ex d IIB T4) cater to environments dealing with flammable or explosive materials. Low maintenance costs, extended component life (e.g., filters lasting ≥1000 hours), and compact, lightweight design facilitate easy installation and future scalability.
