Multi-Effect Evaporation Crystallizer With Integrated Centrifuge for Crystal Separation
Product Spotlights
As a leading manufacturer with nearly a decade of expertise, Qingdao Conqinphi Environmental Technology Group is proud to introduce our advanced Multi-Effect Evaporation Crystallizer with Integrated Centrifuge. This all-in-one system is engineered to maximize energy efficiency and product yield in demanding crystallization processes. We combine robust evaporation technology with precise centrifugal separation to deliver a streamlined solution for industries seeking to reduce operational costs and enhance purity control.
Operating from our expansive 10,000-30,000 sqm facility, we design and build these systems to meet the rigorous standards of global markets, including North America, Europe, and Southeast Asia. Our commitment to integrated manufacturing allows for superior quality control and customization, ensuring the system aligns perfectly with your specific process requirements and output goals.
The core value of this system lies in its seamless integration. By unifying the evaporation, crystallization, and separation stages into a single, coordinated unit, we eliminate intermediate handling, minimize heat loss, and significantly reduce the plant's footprint. This translates directly into lower capital and energy expenditures for our clients, making it a strategic investment for sustainable production.
Key Features & Technical Advantages:
- High-Efficiency Multi-Effect Evaporation: Utilizes latent heat from previous effects to pre-heat feed in subsequent ones, dramatically cutting steam consumption by up to 60-70% compared to single-effect units.
- Integrated Centrifugal Separation: The built-in centrifuge receives the crystal slurry directly from the crystallizer, enabling continuous, closed-loop separation that preserves crystal size and minimizes product loss or contamination.
- Precision Crystallization Control: Advanced controls for supersaturation, temperature, and residence time allow for consistent crystal size distribution (CSD), which is critical for product quality and downstream handling.
- Corrosion-Resistant Construction: Available in materials like 316L stainless steel, Hastelloy, or Titanium to handle aggressive, high-purity, or sanitary process streams common in pharmaceuticals and fine chemicals.
- Automated PLC Control System: Provides precise monitoring and adjustment of all parameters (pressure, temperature, flow, speed), ensuring stable operation, repeatable results, and reduced labor dependency.
- Versatile Heat Source Options: Compatible with steam, thermal oil, or electric heating, offering flexibility to integrate with your existing plant utilities.

Client Benefits:
- Substantial Energy Savings: Multi-effect design recycles heat, slashing utility costs and improving your process's sustainability profile.
- Enhanced Product Quality: Closed, integrated flow minimizes exposure and contamination, yielding purer crystals with consistent size.
- Reduced Operational Complexity: One system manages multiple unit operations, simplifying training, maintenance, and process control.
- Space Optimization: The compact, integrated design requires significantly less floor space than separate evaporation and separation skids.
- Scalable & Future-Proof: Designed with modularity, the system can be scaled or reconfigured to adapt to changing production volumes or new products.

Frequently Asked Questions (FAQ):
1. What industries commonly use this type of integrated system?
This system is highly suitable for the chemical industry (salt, fertilizers, organic acids), pharmaceuticals (APIs, antibiotics), food & beverage (sugar, lactose, citric acid), and for zero-liquid discharge (ZLD) applications in wastewater treatment to recover valuable salts.
2. How does the multi-effect evaporation save energy?
It operates on a cascade principle. Steam heats the first effect; the vapor produced then becomes the heat source for the second effect, and so on. This reuse of latent heat significantly reduces the total fresh steam required per unit of water evaporated.
3. Can the centrifuge handle different crystal sizes and slurry densities?
Yes. The integrated centrifuge (basket, pusher, or decanter type) is selected and customized based on your specific crystal characteristics (size, shape, density) and feed slurry properties to ensure optimal separation efficiency and crystal integrity.
4. Is the system suitable for sterile or sanitary applications?
Absolutely. For pharmaceutical or high-purity food applications, we offer sanitary design features including polished surface finishes, CIP (Clean-in-Place) systems, and validation documentation support to meet relevant standards.
5. What level of automation is provided?
The system comes standard with a PLC and Human-Machine Interface (HMI) for full control. We can provide advanced automation with SCADA, data logging, and remote monitoring capabilities upon request.
6. How is the capacity of the system determined?
Capacity is primarily defined by the required evaporation rate (kg water/hour) and final crystal production rate. We conduct a detailed process analysis based on your feed solution composition, concentration, and desired output to engineer the optimal system size.
7. What after-sales support do you offer?
Our support includes detailed installation manuals, on-site or remote commissioning supervision, operator training, and a comprehensive spare parts program. Our technical team is available for ongoing consultation.
