Vacuum Milk Evaporator

Vacuum evaporation operates at low pressure (0.1-0.3 bar), allowing for boiling at low temperatures (40-70°C), whereas traditional evaporation requires higher temperatures. This fundamental difference preserves the milk proteins, heat-sensitive vitamins, and aromatic compounds, preventing the denaturation and cooked tastes characteristic of intensive heat treatments.

Our patented degassing system uses a combination of vacuum and a dispenser that transforms the milk into a thin film. This configuration creates a sudden pressure drop that expels air and dissolved gases. The system achieves over 95% oxygen removal efficiency, thus preventing oxidation, which is responsible for alterations in color and taste, as well as the loss of nutritional value.

Our evaporators achieve a specific consumption of only 1.1 to 1.3 kg of vapor per kg of water evaporated, thanks to our integrated heat recovery system. This performance is 30-40% higher than traditional evaporators. The MVR (Mechanical Vapor Recompression) option further reduces this consumption to 0.1-0.2 kg of vapor/kg of water, offering substantial energy savings.

Vacuum technology allows for low-temperature processing (40-70°C) that preserves native proteins, prevents the denaturation of lactoglobulins and lactalbumins, and retains heat-sensitive vitamins (B1, B6, B12, C). The elimination of dissolved oxygen prevents lipid oxidation and the degradation of aromatic compounds, guaranteeing a concentrated product with exceptional nutritional and organoleptic qualities.

Vacuum evaporation is a crucial step in optimizing drying. By concentrating the milk to up to 50% dry matter, it significantly reduces the load on the dryer, improving its efficiency by 40-50%. Vacuum-concentrated milk exhibits better drying properties, faster rehydration, and superior functional properties thanks to the preservation of native proteins and the elimination of trapped gases.

Our evaporators are designed for modular integration into existing lines. We offer customized solutions with compatible CIP/SIP interfaces, connectivity with supervisory systems, and installation flexibility to suit space constraints. Our engineering team ensures complete integration, including performance validation and staff training, guaranteeing a smooth transition with minimal production downtime.
