Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. — a professional manufacturer with over 8 years of experience (established in 2015), a factory area of 10,000–30,000 m², and an annual export value of US$10–50 million. Our Triple Effect Falling Film Evaporator (Tubular or Plate Type) is designed to efficiently concentrate liquid solutions in industries such as food, pharmaceuticals, chemicals, and environmental treatment. With three evaporation stages operating in series, this system maximizes heat utilization, reduces energy consumption, and delivers consistent product quality. Whether you need tubular or plate heat exchanger configurations, our evaporator is engineered to meet your specific concentration requirements.
Key Features & Technical Advantages
- Triple Effect Design: Utilizes vapor from the previous effect as heating medium for the next, achieving up to 60–70% steam savings compared to single-effect evaporators.
- Falling Film Technology: Liquid forms a thin film on the heat transfer surface, enabling rapid evaporation at low temperatures, ideal for heat-sensitive products (e.g., fruit juices, dairy, herbal extracts).
- Flexible Heat Exchanger Options: Choose between Tubular (robust, easy to clean) or Plate (compact, high efficiency) configurations based on your space, viscosity, and fouling tendency.
- High Concentration Ratio: Capable of achieving final solids concentration up to 50–70% (depending on product properties).
- Low Residence Time: Minimal thermal degradation of product due to short contact time with hot surfaces.
- Automation & Control: Option for PLC and HMI touch screen for precise temperature, pressure, and flow control; remote monitoring available.
- Sanitary Design: All product contact surfaces are polished to Ra ≤ 0.4 µm, supporting CIP/SIP cleaning and meeting HACCP standards.
- Energy Recovery: Built-in vapor recompression (optional) further reduces operating costs.

Frequently Asked Questions (FAQ)
Q1: What is the difference between tubular and plate type in this evaporator?
A: Tubular type uses straight or coiled tubes inside a shell; it is more robust for viscous or fouling liquids and easier to clean mechanically. Plate type uses pressed plates with gaskets or welded joints; it offers higher heat transfer coefficients and a more compact footprint, suitable for low-fouling, clean fluids.
Q2: Can this evaporator handle heat-sensitive products?
A: Yes. The falling film design provides very short residence time (seconds) at low temperature (vacuum conditions), minimizing thermal degradation. It is ideal for fruit juices, dairy, and pharmaceutical extracts.
Q3: What is the typical steam consumption for a triple effect unit compared to single effect?
A: A triple effect evaporator consumes approximately 0.35–0.4 kg steam per kg water evaporated, whereas a single effect uses about 1.1–1.2 kg/kg. This represents a 60–70% reduction in steam usage.
Q4: Can I get the evaporator with automation and remote monitoring?
A: Yes. We offer PLC-based control with HMI touch screen, and optionally we can integrate remote monitoring via industrial IoT for real-time data logging and alerts.
Q5: What materials are available for the product contact parts?
A: Standard is SS304 or SS316L. For corrosive or high-purity applications, we can supply Duplex stainless steel, Hastelloy, or other alloys upon request.
Q6: How do you ensure the evaporator meets sanitary standards?
A: All surfaces in contact with the product are polished to Ra ≤ 0.4 µm, welded joints are ground and passivated, and the system is designed for CIP (Clean-in-Place) and SIP (Sterilize-in-Place). Our quality management system is certified to HACCP and ISO9001.
Q7: What is the typical delivery time for a custom triple effect falling film evaporator?
A: For standard designs and capacities up to 10,000 L/h, delivery is around 30–45 days after order confirmation. Larger or highly customized units may require 60–90 days. We always confirm the schedule during quotation.
Q8: Can you provide a pilot test or lab-scale trial before purchasing a full-size unit?
A: Absolutely. We have a pilot test facility in Qingdao. Customers are welcome to send samples for testing, or we can provide a small-scale rental unit for on-site trials.
