Welcome: Yiwu Weihao Machinery Equipment Company
As a leading evaporator manufacturer integrating advanced MVR (Mechanical Vapor Recompression) and falling film technologies, Yiwu Weihao Machinery Equipment Company specialize in designing and producing high-performance MVR Falling Film Evaporators. This equipment combines the ultra-energy-saving capability of MVR systems with the high heat transfer efficiency, gentle processing, and low residence time of falling film technology. It is engineered to address the critical challenges of high energy consumption, operational costs, and product degradation in traditional evaporation processes, delivering a superior solution for heat-sensitive materials, high-value applications, and large-scale industrial concentration projects across multiple sectors.
Our MVR Falling Film Evaporator represents the pinnacle of energy-efficient evaporation technology. By compressing secondary steam into reusable high-quality heating steam via a high-efficiency MVR compressor, it eliminates the need for extensive external steam input, making it the most cost-effective and environmentally sustainable concentration solution available. The falling film design ensures the liquid flows as a thin, uniform film along the heating tube walls, maximizing heat transfer area and minimizing residence time. This combination enables exceptional energy savings while preserving the delicate properties of heat-sensitive materials such as flavors, nutrients, and active pharmaceutical ingredients (APIs).
Feed Distribution & Film Formation: The preheated raw liquid is evenly distributed across the inner walls of vertical heating tubes via a precision liquid distributor, forming a thin, downward-flowing falling film. This design ensures maximum contact with the heating surface.
MVR Vapor Recompression: As the liquid film boils under vacuum conditions (-0.06 to -0.095 MPa) to generate secondary steam, the MVR compressor aspirates, compresses, and heats this steam. The compressed steam is then fed back into the heating jackets as the primary heat source, creating a closed-loop energy cycle.
Gentle Evaporation: The compressed steam heats the falling liquid film at a low temperature (45-75°C), causing the solvent (usually water) to evaporate. The short residence time (2-5 seconds) prevents thermal degradation, ensuring the integrity of the original product.
Vapor-Liquid Separation: The concentrated liquid and generated vapor separate naturally in the vapor-liquid separator at the bottom of the unit.
Condensation & Discharge: Non-condensable gases are removed by a vacuum system. The concentrated product is continuously discharged at the desired concentration, while the condensed vapor (pure water) is collected for reuse or discharge.
Unmatched Energy Efficiency: The MVR system reduces steam consumption by 80-90% compared to traditional single-effect evaporators and by 50-70% compared to multi-effect evaporators. This drastically cuts operational costs and carbon footprints, delivering an exceptional return on investment (ROI).
Superior Product Quality: The low-temperature (45-75°C) operation and ultra-short residence time (2-5 seconds) minimize thermal damage, ensuring maximum retention of flavors, colors, nutrients, and bioactivity—critical for premium food, beverage, and pharmaceutical products.
High Heat Transfer Efficiency: The falling film design provides a very high heat transfer coefficient, enabling fast evaporation rates and high throughput (customizable from 100 to 5000 L/h).
Wide Material Compatibility: Ideal for heat-sensitive liquids (fruit juices, dairy, herbal extracts), high-value products (fine chemicals, APIs), and low-viscosity to medium-viscosity materials (up to 1000 cP).
Hygienic & Safe Construction: All product contact parts are fabricated from 316L food-grade or pharmaceutical-grade stainless steel, fully compliant with FDA, GMP, and ISO 22000 standards. Features include CIP (Clean-in-Place) systems for easy sanitation and explosion-proof design for hazardous environments.
Compact & Space-Saving: The vertical, tube-in-shell design occupies a smaller footprint compared to multi-effect systems, making it suitable for both new greenfield projects and retrofits of existing lines.
Intelligent Operation: Equipped with a PLC + HMI control system for precise monitoring and automatic adjustment of key parameters (temperature, pressure, flow rate, concentration). Enables remote operation and unmanned production for enhanced efficiency.
