Multistage liq. vaporising and drying system - removes water leaving dry powder using convection stages, followed by radiation drier

摘要

The multi-stage liquid-vaporising/and drying system converts it into concentrated or powdery material by thermal water extraction, using a series of convection vaporising stages in series and at pressures decreasing in stages, heated by steam. The radiation-vaporiser and/or drier following the early stages work at a higher pressure, and the vapour generated in them is used to heat these stages. A variety of different designs of evaporator may be used.
