Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – Since 2015, we have been a trusted manufacturer of advanced evaporation systems, operating from a 10,000-30,000 square meter facility with an annual export value of US$10-50 million. Our Customized Food Grade Falling Film Evaporator Triple Effect Fruit Juice Concentrator represents the pinnacle of efficiency and quality for the juice industry. Designed to preserve natural flavors, vitamins, and color, this concentrator uses a gentle low-temperature evaporation process that maximizes product quality while minimizing energy consumption. With full customization options, we tailor every unit to your specific capacity, automation level, and process requirements.
This triple-effect falling film concentrator is engineered for continuous operation, offering significant advantages over traditional single-effect units. The falling film technology ensures a thin film of liquid flows down the heated tubes under gravity, resulting in extremely high heat transfer coefficients and short residence times. This prevents thermal degradation and fouling, making it ideal for heat-sensitive products like fruit juices. The triple-effect configuration allows vapor from one effect to heat the next, dramatically reducing steam consumption by up to 60-70% compared to single-effect evaporators. All wetted parts are made from food-grade stainless steel (304/316L), compliant with HACCP and other international hygiene standards.
Key Features & Technical Specifications
- Triple-Effect Falling Film Design: Maximizes energy efficiency and evaporation capacity. Typical steam consumption is only 0.4-0.5 kg steam per kg water evaporated.
- Low-Temperature Operation: Evaporation temperature ranges from 45°C to 75°C, preserving heat-sensitive components. Suitable for orange, apple, grape, and other fruit juice concentrates.
- Customizable Capacity: Available from laboratory/pilot scale (50 L/h) to industrial scale (10,000+ L/h). We design based on your feed flow, Brix input/output, and available utilities.
- Full PLC Automation: Includes touch screen control, automatic CIP (Clean-in-Place), level control, temperature control, and vacuum regulation. Minimal operator intervention required.
- Food-Grade Construction: All product contact surfaces are AISI 304L or 316L stainless steel, polished to Ra ≤0.6 μm. Gaskets are FDA-approved silicone or EPDM.
- Vacuum System: Multi-stage ejector or mechanical vacuum pump to maintain low evaporation temperatures. Optional alcohol recovery system for citrus juice dealcoholization.
- Compact Modular Design: Skid-mounted for easy installation and footprint reduction. Each effect is a separate module that can be integrated on-site.
- Energy Recovery Options: Thermal vapor recompression (TVR) or mechanical vapor recompression (MVR) can be added for even higher efficiency.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between falling film and forced circulation evaporators?
A: Falling film evaporators rely on gravity to distribute liquid as a thin film along heated tubes, providing short residence time and gentle evaporation – ideal for heat-sensitive juices. Forced circulation uses a pump to circulate liquid, suitable for viscous or fouling products. -
Q: How much energy does a triple-effect concentrator save compared to single-effect?
A: Typically, a triple-effect evaporator consumes about 30-40% of the steam used by a single-effect unit for the same evaporation load. This translates to major cost savings in steam generation. -
Q: Can I process different fruit juices in the same machine?
A: Yes, with programmable recipes and CIP (Clean-in-Place) system, you can switch between apple, orange, mango, etc. with minimal downtime. We recommend a flush cycle between products. -
Q: What certifications does your company hold for food equipment?
A: Our company holds HACCP, ISO9001, ISO14000, OHSAS18001, and many other certifications. All product contact materials are food-grade and can be supplied with 3.1 material certificates upon request. -
Q: How long is the delivery time and what is the warranty?
A: Typical lead time is 60-90 days after engineering approval, depending on complexity. We offer a standard 12-month warranty for manufacturing defects, with extended warranty options available. -
Q: Do you provide on-site installation and training?
A: Yes, we can dispatch our engineers for supervision of installation, commissioning, and operator training at an additional cost. Remote support via video call is also available. -
Q: What is the minimum order quantity (MOQ)?
A: Since we specialize in customized solutions, there is no strict MOQ. We welcome pilot-scale units (50 L/h) to full industrial lines. Contact us for your specific needs. -
Q: How do you ensure the juice flavor is retained?
A: Our low evaporation temperature (45-75°C) and short residence time prevent thermal damage. Additionally, an optional aroma recovery system can capture volatile compounds and reintroduce them into the concentrate.
