1.Single effect outer cycle vacuum concentrator is the ordinary type, which is suitable for evaporation of water solution.

    2.It is the alcohol recovery type, which is used for evaporation of alcohol solution. It has higher cooling area to ensure the alcohol recovery. Its recovery strength reaches 70-85°, the alcohol consumption rate is less than 5% and the alcohol temperature after the recovery is less than 40℃.

    3.It is used for single-effect evaporator and thick ointment collection. After the normal single-effect evaporation, the valves connecting the spraying tube and circulating tube in the heating chamber and evaporating chamber will be closed. The liquid materials will fully enter the evaporating chamber and through the jacket heating in the evaporating chamber, normal pressure type or pressure relief type concentration will be carried out. The concentration specific gravity of materials will be increased to 1.35-1.45.
