Welcome: Yiwu Weihao Machinery Equipment Company
TVR Type Falling Film Evaporator
Yiwu Weihao Machinery Equipment Factory specialize in advanced TVR-type falling film evaporators, engineered to address the critical challenge of high energy consumption in industrial evaporation processes. By integrating cutting-edge Thermal Vapor Recompression technology, our equipment transforms low-grade steam into high-quality thermal energy, creating a closed-loop heating system that drastically reduces operational costs and environmental footprint.
Feed Preparation: Raw liquid (juice, milk, wastewater, etc.) is pre-filtered and preheated to an optimal temperature (45–60°C) to ensure uniform flow and reduce viscosity.
Film Formation: The liquid is distributed evenly across the inner walls of vertical heating tubes, forming a thin, falling film that maximizes heat transfer surface area.
TVR Energy Recycling: The TVR system compresses the water vapor generated during evaporation, increasing its temperature and pressure. This recompressed vapor is then fed back into the heating jackets, serving as the primary heat source—eliminating the need for extensive external steam input.
Efficient Concentration: Under vacuum conditions (typically -0.06 to -0.09 MPa), the liquid boils at low temperatures (50–75°C), ensuring gentle processing and minimal degradation of heat-sensitive components.
Continuous Discharge: Concentrated product is continuously removed, with adjustable concentration ratios to meet specific application requirements.
Exceptional Energy Efficiency: The TVR system reduces steam consumption by 60–80% compared to traditional single-effect evaporators and 30–50% compared to multi-effect systems. This translates to significant cost savings and lower carbon emissions.
Superior Product Quality: Low-temperature, vacuum operation preserves the natural flavor, color, nutritional value, and chemical integrity of the processed liquid—critical for premium food, beverage, and pharmaceutical products.
High Heat Transfer Coefficient: The falling film design ensures rapid and efficient heat transfer, enabling fast evaporation rates and high throughput (customizable from 50 to 5000 L/h).
Hygienic & Safe Construction: Constructed from food-grade 316L/304 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 integrated TVR unit and falling film configuration have a smaller footprint compared to multi-effect systems, making it suitable for both new installations and retrofits of existing lines.
Smart Automation: Equipped with a PLC + HMI control system for precise monitoring and adjustment of key parameters (temperature, pressure, flow rate, concentration). Enables remote monitoring and unmanned operation for enhanced efficiency.
