As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. specializes in advanced evaporation systems for industrial applications. Our Triple-effect Plate Evaporator with Shell-and-tube Condenser (Evaporation Capacity: 1500 L/H) is designed to deliver high efficiency, energy savings, and reliable performance for liquid concentration processes. Backed by over 8 years of manufacturing expertise and a modern factory spanning 10,000–30,000 square meters, we ensure each unit meets rigorous quality standards.
This evaporator combines the advantages of plate heat transfer technology with a robust shell-and-tube condenser, making it ideal for heat-sensitive products in the food, pharmaceutical, and chemical industries. The triple-effect design maximizes steam utilization, reducing overall energy consumption by up to 30% compared to single-effect systems. With a capacity of 1500 liters per hour, it is suitable for medium- to large-scale production lines.
Our team of 201–300 skilled employees, together with strict quality control procedures, ensures that every component, from the plates to the condenser, is fabricated precisely. We have exported to markets across North America, South America, Europe, Southeast Asia, Africa, and Oceania, with an annual export value of US$10–50 million. Below we provide detailed technical specifications and benefits.

Product Advantages & Customer Benefits
- Energy Efficiency: The triple-effect design recycles vapor from one effect to heat the next, significantly reducing steam consumption. Typical steam savings reach 30–40% compared to single-effect evaporators.
- High Product Quality: Plate heat exchangers provide gentle heating with short residence time, minimizing thermal degradation of heat-sensitive products such as fruit juices, dairy, and pharmaceutical extracts.
- Robust Condensation: The shell-and-tube condenser efficiently handles large vapor volumes, ensuring stable vacuum conditions and preventing fouling.
- Compact Footprint: The plate-type evaporator section occupies less floor space than traditional tubular evaporators, making it suitable for plant upgrades.
- Easy Maintenance: Plate packs can be disassembled for cleaning or replacement, reducing downtime.
- Customizable Configuration: We offer options for different materials (304/316L), control systems (manual or PLC), and additional accessories like CIP systems.
- Compliance with Standards: Our manufacturing follows ISO9001 and HACCP guidelines, and we can provide certificates upon request.
Detailed Design & Operation
The triple-effect plate evaporator consists of three plate heat exchanger units arranged in series. Feed liquid enters the first effect, where it is heated by steam. The generated vapor then flows to the shell side of the condenser and also serves as the heating medium for the second effect after passing through a vapor compressor if needed. The shell-and-tube condenser is specifically designed to handle the final vapor from the last effect, condensing it with cooling water. This arrangement allows for high thermal efficiency and low operating costs.
Each effect is equipped with a separation chamber to prevent liquid entrainment. The plates are made of stainless steel with herringbone or chevron patterns to enhance turbulence and heat transfer coefficients up to 5000 W/m²·K. The entire system is vacuum-tight, with a vacuum pump maintaining the desired pressure. Optional features include automatic concentration control, data logging, and remote monitoring via SCADA.
Typical applications include concentration of milk, whey, fruit juices, sugar solutions, vegetable extracts, and chemical intermediates. The 1500 L/H capacity is ideal for lines producing 10–15 tons per day of concentrated product. Our engineering team can tailor the design to your specific liquid properties, such as viscosity, foaming tendency, and temperature sensitivity.

Frequently Asked Questions
- What is the difference between a plate evaporator and a tubular evaporator? Plate evaporators use corrugated plates to create a high heat transfer area in a compact design, while tubular evaporators use tubes. Plates are easier to clean and more efficient for low-viscosity, heat-sensitive products.
- Can this evaporator handle high-viscosity liquids? Yes, but we recommend a pre-concentration or a forced circulation design for viscosities above 1000 cP. Our team can evaluate your specific fluid.
- What is the typical steam consumption for 1500 L/H capacity? For a triple-effect system, steam consumption is approximately 0.3–0.4 kg steam per kg water evaporated, depending on temperature and pressure. This is about 30–40% lower than single-effect.
- Is the shell-and-tube condenser made of the same material as the plates? The condenser shell is typically carbon steel or stainless steel, and tubes are stainless steel. We can match materials to your process fluid.
- Do you provide installation and commissioning services? Yes, we offer on-site supervision and training for your team. Additional service fees may apply.
- What certifications are available for this equipment? We can provide material certificates, pressure vessel design calculations, and ISO9001/HACCP compliance documents. Specific certifications like CE or ASME are available upon request at extra cost.
- How long is the warranty period? Standard warranty is 12 months from shipment or 18 months from installation, whichever is earlier. Extended warranty is negotiable.
- Can the evaporator be integrated with an existing CIP system? Yes, we can design a CIP connection for the plate packs and condenser. Please provide details of your current CIP system.
