Qingdao Conqinphi Environmental Technology Group Co., Ltd. introduces its advanced Plate-Type Three-Effect Evaporator specifically designed for low-temperature operation in pharmaceutical extraction processes. As a manufacturer with over 10,000 square meters of factory space and annual export value exceeding US$10 million, we deliver industrial solutions that combine energy efficiency, product quality, and process safety. Our three-effect evaporator uses heat recovery technology to minimize steam consumption while maintaining gentle evaporation conditions that protect heat-sensitive pharmaceutical compounds.
This system is ideal for concentrating herbal extracts, active pharmaceutical ingredients (APIs), and other biological solutions that require low temperatures to preserve potency and purity. The plate-type design offers superior heat transfer efficiency and easy scalability from pilot to production scale. With PLC automation and robust stainless steel construction, it meets the demanding requirements of GMP-compliant pharmaceutical facilities.
Key Features & Benefits
- Low-Temperature Operation: Evaporation occurs at 45–65°C, preventing thermal degradation of delicate pharmaceutical compounds and preserving maximum active ingredients.
- Three-Effect Energy Savings: Reuses vapor from the first effect as heating medium for the second and third effects, reducing steam consumption by up to 60% compared to single-effect evaporators.
- Plate-Type Heat Exchanger: Compact, high-efficiency plates provide large heat transfer area with minimal fouling, easy cleaning, and lower pressure drop.
- Full Automation: PLC with touch screen interface controls temperature, pressure, feed rate, and concentrate density; data logging available for batch records.
- Sanitary Design: All product-contact surfaces made of 316L stainless steel with polished finish (Ra ≤ 0.6 μm), fully drainable, and CIP compatible.
- Customizable Configuration: Available in evaporative capacities from 500 L/h to 5000 L/h, with optional vacuum system for even lower boiling points.
- Comprehensive Safety: Includes over-temperature, over-pressure, and vacuum break protection; meets international safety standards.

Frequently Asked Questions
-
Q: What is the main advantage of a three-effect evaporator compared to single-effect?
A: Three-effect evaporators reuse vapor energy from the first effect to heat the second and third effects, resulting in about 1/3 of the steam consumption per kg of water evaporated. This drastically reduces operating costs for continuous production. -
Q: Can this evaporator handle foaming or viscous pharmaceutical extracts?
A: Yes. Our plate-type design with special flow channels and optional foam-breaker reduces foaming. For viscous liquids, we can adjust the plate gap and circulation rate. We recommend a preliminary test with your sample to optimize configuration. -
Q: What materials of construction are available for product contact parts?
A: Standard is 316L stainless steel with electropolished finish. For certain aggressive solvents or high chlorides, we can supply Hastelloy C-276 or other alloys upon request. -
Q: Is the system easy to clean for product changeover?
A: Absolutely. The plate heat exchanger can be opened for manual cleaning, and the entire system is designed for CIP (Clean-in-Place). Automated CIP cycles can be programmed into the PLC. -
Q: What certifications does the equipment meet?
A: Our evaporators are manufactured under ISO9001 quality management system. We can also provide CE marking, ASME or PED compliance if required for your region. Please specify your certification needs when ordering. -
Q: How long is the delivery time for a standard unit?
A: Typical lead time is 45–70 days after order confirmation, depending on capacity and customization. We also offer expedited production for urgent projects. -
Q: Do you provide installation and training?
A: Yes. Our service team can supervise on-site installation and provide comprehensive training for operators and maintenance staff. Remote support is also available. -
Q: Can the evaporation temperature be lowered further?
A: By integrating a vacuum system and adjusting the pressure profile, we can achieve evaporation temperatures as low as 30°C. This option is available for extremely heat-sensitive products. Please consult our engineers for more details.
