Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015, is a leading manufacturer specializing in advanced evaporation and wastewater treatment solutions. With a factory spanning 10,000–30,000 square meters and over 200 skilled employees, we deliver robust, energy-efficient MVR evaporators tailored for juice concentrate, dairy processing, and pickling wastewater applications. Our systems combine mechanical vapor recompression (MVR) technology with intelligent automation to achieve up to 95% wastewater reduction while recovering high-quality condensate and concentrated by-products. This not only lowers operational costs but also helps you meet stringent environmental discharge standards.
The MVR Evaporator is designed to handle high‑BOD/COD streams from fruit juice concentration, dairy whey or permeate, and pickling brines containing salt, acids, and organic residues. By reusing the latent heat of vaporized steam, our system consumes 80–90% less energy compared to traditional multi‑effect evaporators. The result is a compact, cost‑effective solution that maximizes resource recovery and minimizes waste discharge.
Key Features & Technical Specifications
- Energy Efficiency: MVR technology reduces steam consumption – only a small amount of auxiliary steam is needed for start‑up. Typical COP > 20.
- Wide Feed Compatibility: Suitable for acidic/alkaline pickle brine (pH 2–12), dairy liquids (whey, milk concentrate), and fruit juice with high sugar content.
- Modular Design: Skid‑mounted or containerized options for easy installation and relocation. Capacity ranges from 500 L/h to 50,000 L/h per unit.
- Advanced Control: PLC system with HMI touch screen monitors temperature, pressure, flow, and concentration in real time. Remote monitoring available.
- Corrosion‑Resistant Materials: Available in SS304, SS316L, or special alloys (e.g., duplex steel) for aggressive pickle liquor.
- Low Fouling Design: Special tube geometry and circulation speed minimize scaling in dairy and juice applications.
- Compliance: Designed to meet international environmental standards; components carry ISO9001, ISO14000, OHSAS18001, and HACCP certifications (upon request).

Benefits to Your Business:
• 60–80% reduction in disposal costs – convert wastewater into reusable water and concentrated by‑products (e.g., salt, sugar, protein).
• Minimal chemical addition – simple evaporation process avoids complex treatment trains.
• Fast payback – many clients recover investment within 12–18 months through water savings and reduced hauling fees.
• Environmentally friendly – zero liquid discharge (ZLD) achievable with downstream crystallizer or dryer.
• Scalable – multiple units can be paralleled for large‑volume applications.
Our product line covers MVR, falling film, forced circulation, and hybrid evaporators. We also provide turnkey solutions including pre‑treatment, piping, and automation integration. All equipment undergoes strict quality checks and factory acceptance tests before shipment.

Frequently Asked Questions
-
What is the difference between MVR and traditional multi‑effect evaporators?
MVR uses a mechanical compressor to recycle vapor latent heat, reducing steam consumption by 80–90% compared to multi‑effect evaporators. It also has a smaller footprint and simpler operation. -
Can this evaporator handle high‑salt pickling wastewater (e.g., NaCl up to 20%)?
Yes. Our MVR evaporator is designed with corrosion‑resistant materials and anti‑scaling features to handle brine with salt concentrations up to saturation. The forced circulation option prevents crystallization inside the tubes. -
What is the typical payback period?
Payback depends on wastewater volume and local disposal costs. For most applications with flow above 10 m³/day, payback is within 12–18 months. We provide a detailed financial analysis with your quotation. -
Do you provide installation and training?
Yes. Our service includes on‑site installation supervision, commissioning, and operator training (typically 5–7 days). Remote support is also available. -
What certifications does your equipment carry?
Our production facilities are certified to ISO9001, ISO14000, OHSAS18001, HACCP, and more. Specific product certifications (e.g., CE, ASME) can be arranged upon request. -
Can you customize for juice concentrate with high sugar content (e.g., 65°Brix)?
Absolutely. Our falling‑film MVR evaporator is widely used in fruit juice concentration, achieving up to 70°Brix without thermal damage. The low temperature operation (below 70°C) preserves flavor and nutrients. -
What is the lifespan of the compressor and heat exchanger?
With proper maintenance, compressor service life exceeds 10 years. Heat exchanger tubes typically last 5–8 years before replacement, depending on feed corrosivity. -
How do I get a quotation?
Please send us your wastewater analysis (pH, TDS, COD, flow rate, temperature) and desired concentration. Our engineers will design a custom system and provide a detailed quote within 48 hours.
