Qingdao Conqinphi Environmental Technology Group Co., Ltd., a professional manufacturer established in 2015 with a factory area of 10,000–30,000 square meters and an annual export value of US$10–50 million, proudly presents our Double-effect Falling Film Evaporator for Food Processing, 500kg/h, Steam Heated, Sanitary Design. This advanced evaporator combines high thermal efficiency with strict hygiene standards, making it an ideal solution for concentrating fruit juices, dairy products, extracts, and other liquid foods. Our team of 201–300 experienced employees ensures every unit meets rigorous quality control, delivering reliable performance for global food processors.
The double-effect falling film design maximizes energy utilization by using vapor from the first effect to heat the second effect, reducing steam consumption by up to 40% compared to single-effect units. With a capacity of 500 kg/h of water evaporation, this evaporator is well-suited for medium-scale production lines. The sanitary design features smooth surfaces, no dead corners, and easy CIP cleaning, fully complying with food industry requirements.
Key Features & Technical Specifications
- Double-Effect Energy Saving: Two-stage evaporation reduces steam consumption; vacuum operation lowers boiling point for heat-sensitive products.
- Sanitary Design: All product contact parts are made of stainless steel 304 or 316L, with polished surfaces (Ra ≤ 0.5 μm) and no crevices to prevent bacterial growth.
- Steam Heated: Uses saturated steam as heating medium, with automatic pressure control for stable operation.
- Gentle Evaporation: Falling film principle ensures short residence time (typically 2–5 minutes) at low temperature, preserving product flavor, color, and nutrients.
- PLC Control System: Touch screen interface monitors temperature, pressure, flow rate, and concentration; data logging and alarm functions available.
- Compact Footprint: Vertical design saves floor space; easy to install and integrate into existing production lines.
- Customizable Options: Additional features like MVR integration, CIP nozzles, or automatic cleaning can be provided upon request.
