Because of liquid film's turbulence due to blade's wiping action, and considered to be the ideal equipment, featuring short detained time, scale eliminating and high viscosity handling, for specialized evaporation and concentration applications for heatsensitive and viscous products. 因刮板对液膜的刮擦作用使液膜呈不断搅动状态,刮膜薄膜蒸发器有停留时间短、消除结焦结垢及处理粘度大等特点,认为其是处理热敏性和高粘性物质蒸发浓缩的理想设备。
