As a leading manufacturer in environmental and process technology, Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our advanced PLC Controlled Double Four-effect Evaporator. Engineered specifically for the demanding requirements of pharmaceutical concentration, this system represents a significant leap in efficiency, precision, and operational control. Since our establishment in 2015, we have dedicated ourselves to developing industrial solutions that meet rigorous international standards. Our evaporator is designed to address the critical needs of pharmaceutical producers: achieving high-purity concentration, maximizing energy recovery, and ensuring batch-to-batch consistency under fully automated control. This system is not just equipment; it's a cornerstone for enhancing your production line's productivity and product quality.
The core of our evaporator lies in its sophisticated Double Four-effect design coupled with a state-of-the-art Programmable Logic Controller (PLC). This combination delivers unparalleled performance for concentrating heat-sensitive, viscous, or foamy pharmaceutical solutions like herbal extracts, syrups, or API intermediates.
- Advanced PLC Control & HMI Interface: The system is governed by a fully automated PLC with a user-friendly Human-Machine Interface (HMI) touch screen. Operators can easily set, monitor, and log all critical parameters such as temperature, pressure, flow rate, and density. The system allows for recipe management, automatic sequencing, alarm handling, and data recording for traceability, which is crucial for pharmaceutical compliance.
- High-Efficiency Double Four-effect Design: Unlike standard multi-effect evaporators, the "double" configuration essentially provides two parallel four-effect streams. This innovative design dramatically increases the evaporation surface area and processing capacity without proportionally increasing the footprint. It utilizes the vapor from one effect to heat the next, significantly reducing steam consumption and operational costs.
- Superior Product Quality Preservation: The falling film evaporation principle ensures a short residence time and low operating temperature for the product, minimizing thermal degradation. This is vital for preserving the active pharmaceutical ingredients (APIs) and the efficacy of the final product.
- Robust & Sanitary Construction: All product contact parts are constructed from high-grade 316L stainless steel, offering excellent corrosion resistance and meeting sanitary requirements. The design facilitates easy cleaning (CIP - Clean-in-Place) and inspection, supporting cGMP (current Good Manufacturing Practice) standards.
- Comprehensive Safety & Monitoring: The system integrates multiple safety features, including pressure relief valves, level sensors, and temperature cut-offs, all monitored by the PLC. This ensures safe, unattended operation and protects both the product and the equipment.

Frequently Asked Questions (FAQ)
Q1: What does "Double Four-effect" mean in this evaporator?
A1: "Double Four-effect" refers to an innovative configuration where two parallel sets of four-effect evaporation stages operate simultaneously. Each "effect" uses vapor from the previous stage as a heating source. This design essentially doubles the processing capacity and heat recovery efficiency compared to a standard single-line four-effect evaporator, leading to higher throughput and even greater energy savings.
Q2: How does the PLC system improve the concentration process?
A2: The PLC system automates the entire operation, from start-up and sequencing to shutdown and cleaning. It precisely controls parameters like temperature, vacuum, feed flow, and product density, ensuring consistent output batch after batch. It also provides real-time monitoring, data logging for audit trails, alarm management, and remote access capabilities, enhancing both quality control and operational safety.
Q3: Is this evaporator suitable for my specific pharmaceutical extract?
A3: Our evaporators are highly customizable. The falling film design is well-suited for heat-sensitive and viscous materials common in pharmaceuticals. To ensure optimal performance, we would need to know details such as your feed solution's properties (viscosity, solids content, foaming tendency), desired final concentration, and required hourly capacity. We then engineer the system accordingly.
Q4: What are the primary energy savings with this system?
A4: Energy savings are achieved through the multi-effect principle. In a four-effect system, only the first effect requires fresh steam input. The vapor produced in the first effect becomes the heating source for the second, and so on. This cascading reuse of latent heat can reduce steam consumption by approximately 75% compared to a single-effect unit, making it a highly cost-effective solution.
Q5: What maintenance does this evaporator require?
A5: Maintenance is minimal due to robust construction and automated operation. Key routine tasks include periodic inspection of pumps and seals, checking instrumentation calibration, and executing automated CIP cycles. The PLC system can also provide predictive maintenance alerts based on operational data. We provide comprehensive manuals and support to guide your maintenance team.
Q6: Can the system be integrated into our existing production line?
A6: Yes, absolutely. Our engineering team designs these systems with integration in mind. We can customize the inlet/outlet connections, control system communication protocols (e.g., Profibus, Ethernet/IP), and overall layout to interface seamlessly with your upstream and downstream equipment, such as reactors, filters, or dryers.
Q7: What safety features are included?
A7: Safety is paramount. The system includes multiple layers of protection: pressure relief devices, high/low level alarms and cut-offs in critical vessels, temperature sensors with automatic shut-off, and emergency stop functions. All these are integrated into the PLC, which continuously monitors the system's status and can initiate safe shutdown procedures if any parameter goes out of range.
Q8: Do you provide installation support and training?
A8> Yes, we offer comprehensive services. This typically includes supervision of installation and commissioning at your site by our experienced engineers. We also provide detailed operational and maintenance training for your personnel to ensure they are fully confident in running and caring for the equipment efficiently and safely.
