Welcome: Yiwu Weihao Machinery Equipment Company
Vacuum Evaporator
As a leading manufacturer of industrial evaporation equipment, Yiwu Weihao Machinery Equipment Company designs and manufactures high-performance vacuum evaporators for low-temperature concentration and purification across multiple industries. Our vacuum evaporators operate under reduced pressure, significantly lowering the boiling point of liquids—making them ideal for heat-sensitive materials that would degrade at standard evaporation temperatures.
A vacuum evaporator works by creating a sealed, low-pressure environment inside the evaporation chamber. This reduces the boiling point of the feed liquid, allowing it to vaporize at a temperature much lower than its normal boiling point.
The liquid is introduced into the heating chamber, where it exchanges heat with steam or hot oil in the jacket or heating tubes. Under vacuum, the solvent evaporates rapidly, and the generated vapor is drawn out by a vacuum pump or condensed in a condenser. The concentrated product is discharged from the bottom of the unit, while the condensed solvent is collected separately. This low-temperature evaporation process protects the integrity of valuable components, preserving flavor, aroma, and nutritional properties.
Low-Temperature Operation: Boiling point reduction under vacuum protects heat-sensitive materials (food, pharmaceuticals, bio-solutions).
High Concentration Efficiency: Optimized heating surface and vacuum system design ensure rapid evaporation and high concentration ratios.
Energy-Saving Options: Available in single-effect, multi-effect, and combined with MVR/TVR systems for maximum energy savings.
Easy Operation & Maintenance: Full automatic control system, user-friendly interface, and quick-disconnect components for easy cleaning (CIP compatible).
Wide Material Adaptability: Suitable for liquids with low to medium viscosity, high-salt solutions, and slurries.
Food & Pharmaceutical Grade: Constructed from food-grade 304/316L stainless steel, meeting GMP and food safety standards.
