External cycling heating and vacuum negative pressrue evaporating principle are applied together, with high evaporating speed, high condensed specific gravity, no bubbles of materials emerge duing the condensing process, without pollution, and capability of alcohol reclaiming is quite high. It is easy to clean, convenient to operate, with small area occupied. little investment, nice appearance, high efficiency and so on.

So it iswidly used in production of foods, beveragers, Chinese traditional medicines, western medicines. and alcohol reclaiming. It complies with "GMP"and "HACCP"standards.
