Pure Steam Generator

Producing pharmaceutical-grade pure steam for pharmaceutical, food and cosmetic manufacturing applications

The pure steam generator is designed to produce high-quality clean steam using purified water as feed water and industrial steam as the heating source. This equipment is widely used in pharmaceutical manufacturing as well as food and cosmetic production lines for sterilizing pipelines, tanks, and other process equipment. The condensate from the produced pure steam meets the stringent requirements of the Chinese Pharmacopoeia (CP 2020), United States Pharmacopeia (USP 43), and European Pharmacopoeia (EP 10) for Water for Injection (WFI).

Performance
  • Dryness ﹥ 97% – minimizes residual water content
  • Superheat ﹤ 2°C – delivers consistent thermal energy
  • Non-condensable gases ﹤ 2% – ensures clean steam quality

Working Principle

Purified feed water is pressurized by a multi-stage pump and first preheated in a pipeline condenser using waste heat. The water then passes through preheater 2 and preheater 1 for additional heat exchange before entering the evaporator. Inside the evaporator, a water distributor sprays the feed water along the inner wall of the heating tubes, forming a thin film that is rapidly vaporized by industrial steam.

The generated secondary steam, carrying fine water droplets, moves to the steam-water separation system. Through three stages of separation, the droplets are removed, producing ultra-clean pure steam suitable for pharmaceutical-grade sterilization and cleanroom applications.

Pure Steam Generator
  • A: Three-stage separation: Falling-film evaporation, gravity separation, and helical swirling flow.
  • B: Non-condensable gas removal: Optimized separation point for effective non-condensable gas discharge.
  • C: Dual preheaters: Even heat distribution with condensate drainage and heat recovery, reducing energy consumption.
  • D: Feedwater condenser: Uses discharged condensate to preheat incoming feedwater.
Features
  • Structural design: The evaporator, preheaters, and condenser are built with a dual-tube sheet design using inner tube expansion and outer weld construction, preventing cross-contamination.
  • Separation system: A three-stage separation process—including falling-film evaporation, gravity separation, and helical swirling flow—ensures high-purity steam output.
  • Material construction: All parts in contact with feed water, pure steam, and steam condensate are made of SS316L stainless steel, ensuring corrosion resistance and compliance with pharmaceutical hygiene standards.
  • Thermal insulation: The evaporator and preheaters are insulated with aluminum silicate needle-punched blankets, offering excellent flexibility, light weight, superior heat retention, and strong dimensional stability.
  • Surface finish: Internal and external surfaces undergo electropolishing to maintain a smooth, hygienic, and easy-to-clean finish.
  • Energy efficiency: The evaporator and separator are connected to form a large communicating vessel that optimizes heat recovery. The equipment reaches full production capacity rapidly from standby mode. Feedwater is precisely controlled by liquid level sensors to maximize utilization and save energy. Additionally, preheater 2 uses industrial steam condensate for preheating, further reducing energy consumption.
  • Piping and welding: Stainless steel pipes are formed with direct stretch bending to minimize weld seams. Where welding is necessary, argon-protected automatic welding with single-sided weld and double-sided forming technology is used, ensuring weld quality. Welded joints are electropolished after fabrication.
  • Validation documentation: Supplied with endoscopic inspection photos, weld maps, pressure test reports, passivation records, and complete system design documentation for qualification and validation purposes.
  • Control system: Fully automated HMI + PLC control with a simple, user-friendly interface. Multiple communication modes are available, and at least three access permission levels can be configured for operational security.
  • Online monitoring: Real-time monitoring of conductivity, temperature, and flow parameters. Data recorders can be configured as paperless or paper-based options to log and print critical process data.
  • Regulatory compliance: Optional electronic signatures and electronic records enable full audit trail functionality. The control system is designed to comply with GAMP 5 guidelines and 21 CFR Part 11 requirements.
