304 Stainless Steel Tubular Three-Effect Evaporator With PLC Control for Efficient Concentration
Product Spotlights
Efficient Concentration with Advanced Tubular Three-Effect Design
As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been dedicated to producing high-quality industrial evaporation systems since 2015. Our 304 Stainless Steel Tubular Three-Effect Evaporator with PLC Control represents a breakthrough in thermal concentration technology, offering exceptional energy efficiency and precise process management. Built with corrosion-resistant materials and intelligent automation, this equipment is ideal for industries requiring gentle yet effective concentration of heat-sensitive liquids, such as food processing, pharmaceuticals, and chemical production.
The three-effect design maximizes heat utilization by reusing vapor from each effect, significantly reducing steam consumption compared to single-effect units. Combined with PLC-based automation, operators can achieve consistent product quality with minimal manual intervention.
Key Features and Technical Specifications
- Construction Material: All wetted parts are made of 304 stainless steel, ensuring excellent corrosion resistance and compliance with sanitary standards.
- Three-Effect Evaporation: The tubular heat exchanger design allows for high heat transfer coefficients and reduced fouling, enabling efficient concentration of various liquids.
- PLC Control System: Equipped with a user-friendly HMI touch screen, the PLC monitors and adjusts temperature, pressure, flow rate, and liquid level in real time. Parameters can be preset for different products.
- Energy Saving: The multi-effect configuration can save up to 60% steam consumption compared to traditional single-effect evaporators, lowering operating costs.
- Compact Footprint: Despite high capacity, the tubular design offers a smaller floor space requirement compared to falling film or forced circulation alternatives of similar capacity.
- Easy Maintenance: Modular construction allows easy access to heating tubes and separators for cleaning and inspection.

Frequently Asked Questions
Q1: What materials are used in the construction of the evaporator?
All product-contact parts are made of 304 stainless steel as standard. Optional 316L stainless steel is available for more corrosive applications.
Q2: Can the PLC control system be customized for specific recipes?
Yes, the PLC programming allows for multiple predefined recipes to be stored, and parameters such as temperature, pressure, and flow can be adjusted through the HMI.
Q3: What is the typical evaporation capacity range?
Standard capacities range from 500 kg/h to 10,000 kg/h. Custom systems can be engineered for higher or lower throughput upon request.
Q4: Does the evaporator require special installation conditions?
It requires a stable foundation, connections to steam supply, cooling water, and electrical power. Our technical team will provide detailed installation requirements based on your site.
Q5: What maintenance is needed for the tubular heat exchangers?
Regular inspection and periodic cleaning of the tubes are recommended. The CIP system option simplifies cleaning without disassembly.
Q6: Is this evaporator suitable for concentrating fruit juice or milk?
Absolutely. The low-temperature operation (vacuum) preserves flavor and nutrients, making it ideal for food and dairy applications.
Q7: What certifications does your company hold?
We are certified with ISO9001, HACCP, OHSAS18001, and other relevant standards. Specific certifications can be provided upon request.
Q8: What is the lead time for delivery?
Typically 30–45 days after order confirmation, depending on configuration and order quantity. Rush orders can be discussed.
