Welcome: Yiwu Weihao Machinery Equipment Company
Yiwu Weihao Machinery Equipment Factory designs and produces high-performance falling film evaporators specifically for juice and milk concentration. This equipment is the core of food and beverage processing lines, specially developed to solve the problems of nutrient loss, flavor deterioration and high energy consumption in traditional concentration methods, achieving gentle, efficient and energy-saving concentration while maximizing the retention of natural nutrients and original flavor of juice and milk.
Pre-filter and preheat the raw juice/milk to 45–60°C to ensure uniform feeding and reduce viscosity.
The preheated juice/milk forms a uniform thin film on the inner wall of vertical heated tubes through gravity and precision distribution device.
Operate under low vacuum (–0.06 to –0.085 MPa) to lower the boiling point of water to 50–70°C, with short residence time (3–8 seconds) to avoid nutrient degradation and color change.
The water vapor generated during concentration is condensed into pure water for recycling or discharge, realizing energy reuse.
The concentrated juice/milk is continuously discharged, and the concentration ratio can be adjusted (1.5:1 to 10:1) to meet different product requirements.
Nutrient Retention: Low-temperature vacuum operation effectively retains vitamins, proteins, flavors and natural colors of juice and milk.
High Concentration Efficiency: Fast evaporation speed, high heat transfer coefficient, and stable continuous operation.
Food-Grade Sanitation: Made of 316L/304 stainless steel, fully compliant with food safety standards (FDA, GMP, ISO 22000).
Energy-Saving & Environmental Protection: Adopt heat recovery technology, saving 30–50% energy compared with traditional evaporators; no harmful emissions.
Wide Adaptability: Suitable for various juices (fruit juice, vegetable juice) and milk (fresh milk, skim milk, condensed milk) concentration, customizable capacity.
Easy Operation & Maintenance: PLC automatic control system, real-time monitoring of parameters; smooth inner tube wall, easy to clean and maintain.
