No.
The vacuum dryer is mainly used to evaporate the moisture and solvent in the material to achieve the purpose of drying. Under high vacuum, the moisture and solvent in the material evaporate quickly at lower temperatures, and the design and operation of the vacuum dryer are not suitable for the water concentration process. To achieve the concentration of water, other types of equipment are required, such as evaporators or concentrators. These devices can separate water from a solution through the process of heating and evaporation, and increase the water concentration in the solution.
