Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a professional manufacturer with over 8 years of experience in the environmental and pharmaceutical equipment industry. We are proud to introduce our Sanitary Plate-Type Three-Effect Evaporator, engineered with premium 316L stainless steel and an IP65 waterproof enclosure. This evaporator is specifically designed for high-purity applications in the food, dairy, pharmaceutical, and fine chemical sectors, offering exceptional energy efficiency and reliable performance even in demanding environments.
Our three-effect plate-type evaporator utilizes advanced countercurrent flow technology to maximize heat recovery, reducing steam consumption by up to 60% compared to single-effect systems. The 316L material ensures excellent corrosion resistance and meets strict sanitary standards, while the IP65-rated enclosure protects internal components from dust, moisture, and washdown scenarios – making it ideal for cleanroom and hygienic production areas.
Key Features and Technical Advantages
- 316L Stainless Steel Construction: All product contact parts are made of 316L, offering superior resistance to chlorides, acids, and alkalis. The surface finish is Ra ≤ 0.4 μm, fully compliant with cGMP and FDA requirements.
- Three-Effect Evaporation Design: Three plate-type heat exchangers connected in series allow progressive concentration of liquid with minimal energy input. The overall heat transfer coefficient (OHTC) reaches 2500–3000 W/m²·K, significantly higher than traditional tubular evaporators.
- IP65 Waterproof Enclosure: The electrical cabinet and control panel are rated IP65, ensuring safe operation in high-humidity and washdown environments. All connectors and sensors are sealed to prevent ingress of water or dust.
- Sanitary Plate-Type Heat Exchanger: Plates are gasketed and easily disassembled for inspection and cleaning (CIP/SIP compatible). The design eliminates dead corners and reduces risk of product contamination.
- Intelligent PLC Control (Optional): Equipped with an HMI touchscreen and Siemens PLC, the system automates feed, temperature, vacuum, and discharge operations. Remote monitoring and data logging are available upon request.
- Energy Saving: With three-effect operation, the steam consumption is only about 0.3–0.4 kg steam per kg of water evaporated, achieving an economic coefficient of up to 3.0.
- Compact Footprint: The plate-type structure occupies 40% less floor space than conventional falling film evaporators, simplifying installation in existing facilities.

Benefits to Your Production
- Enhanced Product Quality: Low temperature evaporation (as low as 50°C) preserves heat-sensitive nutrients, flavors, and active pharmaceutical ingredients.
- Reduced Operating Costs: Three-effect heat integration cuts steam consumption by 50–60% compared to single-effect units; PLC automation minimizes labor requirements.
- Easy Maintenance & Cleaning: Plate packs can be opened without tools, enabling thorough CIP cleaning and quick inspection. Gaskets are replaceable, extending service life.
- Compliance with Sanitary Standards: 316L material with electropolished surfaces meets EHEDG, 3-A, and cGMP guidelines, ensuring safe production for dairy, juice, and pharmaceutical liquids.
- Long Equipment Life: The IP65 enclosure protects electronics from washdown, while the corrosion-resistant 316L withstands aggressive cleaning agents like HNO₃ and NaOH.

Frequently Asked Questions
1. What is the advantage of using 316L stainless steel for this evaporator?
316L contains molybdenum and has a lower carbon content, offering superior resistance to corrosion from chlorides, acids, and alkaline cleaning solutions. It is the preferred material for pharmaceutical and food-grade equipment to prevent product contamination and ensure long service life.
2. Can this evaporator handle high-viscosity liquids or products with suspended solids?
The plate-type design is suitable for low to medium viscosity liquids (up to about 500 cP). For products with fibers or large particles, we recommend pre-filtration or a different evaporator type (e.g., forced circulation). Please provide your product details for a feasibility assessment.
3. What is the typical energy saving of a three-effect vs. single-effect evaporator?
A three-effect evaporator typically reduces steam consumption by 60–70% per kilogram of water evaporated. For example, if a single-effect uses 1.0 kg steam/kg water, a three-effect uses only 0.3–0.4 kg steam/kg water, resulting in significantly lower operating costs.
4. Is the IP65 enclosure truly necessary? What environment is it designed for?
IP65 (Ingress Protection 65) means the enclosure is dust-tight and protected against water jets from any direction. It is essential for environments where regular washdowns occur (e.g., dairy, brewery, pharmaceutical cleanrooms) to prevent electrical failures and ensure operator safety.
5. Do you provide automation and remote monitoring?
Yes, we can integrate a PLC with touchscreen HMI and optional SCADA interface. Remote monitoring via Ethernet or 4G is available on request. The system can log all process parameters for batch traceability.
6. How long is the delivery time and what are the shipping terms?
Standard delivery is 30–45 days after order confirmation, depending on complexity and current production load. We ship from Qingdao Port, and can arrange FOB, CIF, or CFR as per your preference.
7. What certifications does your company hold?
Our factory is certified with ISO9001, ISO14001, HACCP, OHSAS18001, QS9000, and several other quality and environment management systems. Specific product certifications can be applied for based on your regulatory requirements.
8. Can you customize the evaporator for a specific capacity or liquid?
Absolutely. We offer full customization: capacity from 200 L/h to 5000 L/h, tailored plate configurations, special gasket materials (EPDM, FKM, PTFE), and integrated CIP/SIP systems. Provide your process parameters for a custom design.
