1) Alcohol recovery: It possesses large recovery capacity. Adopt the vacuum science and technology operational method and reform the equipment technological flowchart. The recovery rate can reach 95%. The alcohol consumed rate lowers 5%, reduce 30% energy consumption. It is energy-saving equipment with small investment and high recovery profit 2) Liquid material: combination of external heating cycling and vacuum vaporizing; quick vaporizing; high condensing specific gravity (1.3); simple operation; small ground covering; nice appearance; Intact producing material after heating, evaporating, keeping warm. 0
