Range of Application

The series of single-effect evaporators have three types

1. WZsingle-effect external circulation vacuum concentrator is the ordinary type, which is used for evaporation of water solution.
2. WZH single-effect external circulation vacuum recovery concentrator 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 40º C.
3. WZS single-effect external circulation vacuum ointment collection concentrator is used for single-effect evaporation 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. 

cold extraction principle :

Under the function of high pressure difference, the cells of the material object burst instantly (break the wall), the original object swell to several times or dozens of times, so that the effective components fully contact the solvent so as to achieve as high as 95% efficient extraction rate. After liquid & solid separation, the residue won’t be wasted, after fermentation, it can be made into organic fertilizer.
