As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established 2015, factory area 10,000-30,000 m², over 200 skilled employees), we are proud to present our Plate-type Four-effect Evaporator — a high-efficiency solution for concentrating liquid products in industries such as food, dairy, pharmaceutical, and chemical. This unit comes complete with a Mill Test Report, standard compliance documentation, and on-site installation included, ensuring you receive a ready-to-operate system without hidden costs. Our evaporator integrates advanced plate heat exchange technology to deliver excellent heat transfer rates and minimal energy consumption. Backed by over US$10-50 million annual export value and a dedicated R&D team, we guarantee reliable performance for long-term production.
The Plate-type Four-effect Evaporator utilizes a four-effect evaporation process to maximize steam economy. Each effect operates at a progressively lower temperature and pressure, allowing vapor from the previous effect to be used as heating medium. This design reduces overall energy usage by up to 60% compared to single-effect evaporators. The compact plate-type configuration offers distinct advantages over traditional tubular evaporators: higher heat transfer coefficient, smaller footprint, easier cleaning, and the ability to handle heat-sensitive products with minimal degradation.
Key Features & Technical Specifications
- High Thermal Efficiency: Plate heat exchangers with turbulent flow ensure excellent heat transfer (coefficient up to 3000-6000 W/m²·K), reducing steam consumption.
- Four-effect Design: Reuses vapor three times, achieving steam economy of 4.0-5.0 kg water evaporated per kg steam.
- Low Operating Temperature: Final effect operates as low as 55°C, perfect for heat-sensitive materials like fruit juice, milk, and herbal extracts.
- Compact Footprint: Plate-type structure saves floor space (about 30-50% less than tubular design).
- Easy Maintenance: Plates are individually replaceable, and the frame can be opened for inspection and cleaning without special tools.
- Automation: PLC control with touch screen (Siemens or Mitsubishi optional) for continuous monitoring of temperature, pressure, flow, and concentration.
- Compliance & Testing: Mill Test Report confirms material traceability, pressure testing, and dimensional checks. The unit is built to international standards (ASME, CE, GB150 upon request).
- Included Installation: Our experienced engineers supervise on-site installation, commissioning, and basic operator training. You only need to prepare utility connections.

Frequently Asked Questions (FAQ)
-
What is the difference between plate-type and tubular evaporators?
Plate-type evaporators use corrugated metal plates to create thin films, offering higher heat transfer coefficients, smaller footprint, and easier cleaning. Tubular evaporators are better for very viscous or fouling products but require more space and are harder to maintain. -
Is the installation truly included? What does it cover?
Yes, installation is included in the price. It covers on-site supervision and basic assembly by our engineer (your crew assists). We connect the unit to your utilities (steam, water, electricity), perform trial runs, and train your operators. Travel and accommodation for the engineer are at client’s cost unless otherwise negotiated. -
What certificates are provided with the Mill Test Report?
The Mill Test Report includes material certification (chemical composition, mechanical properties), pressure test results, dimensional inspection, and welding records if applicable. It is issued per the standard you require (e.g., EN10204 3.1). -
Can this evaporator handle highly viscous or scaling products?
The plate-type design is suitable for low to medium viscosity (up to ~500 cP). For high-viscosity or heavily scaling products, we recommend forced circulation or falling film plate design. Please provide your product properties for a customized solution. -
What is the lead time and payment terms?
Standard lead time is 60-90 days after down payment. Payment terms: 30% T/T advance, 70% before shipment or L/C at sight. For customized orders, timeline may vary. -
Do you provide spare parts and after-sales service?
Yes, we maintain a stock of common spare parts (gaskets, plates, seals). We offer remote technical support and can send engineers for troubleshooting if needed. Extended warranty is optional. -
What production capacity ranges are available?
We design from 500 kg/h to 20,000 kg/h evaporation capacity. Smaller pilot-scale units are also available for testing. Please specify your required throughput. -
Can the evaporator be integrated with existing control systems?
Yes, our PLC supports standard communication protocols (Modbus, Profibus, Ethernet IP) for integration with SCADA or DCS. Customization is possible.
