Two Stage Lab Wiped Film Short-path Distillation

Introduction

Two stage short path evaporators can be combined to multi-stage systems. 

When the concentration is a required, the concentrate of the first stage evaporator enters the second stage for further concentration. When the distillate is the product, the distillate of the first stage evaporator enters the second stage for further purification to obtain high concentration distillate. The whole two stage wiped film molecular distills including short path evaporator(SPE), feeding system, heating system, cooling system, collection system and vacuum system.

Product Features

• Two stage system:  Short path distillation(SPD) 

• High heat transfer efficiency, fast evaporation speed and short material residence time.

• Heating area:0.05m2, 0.1m2, 0.2m2, 0.5m2, 1m2, 2m2, 4m2, 6m2 available.

• Continuous distillation process; Low fouling on evaporator wall.

• Trace heating of individual sections (feed, residue and distillate) for melting or viscous products.

• Combination with additional evaporation stages (Colume, Degassing stage, etc)

• SPE constructed of Borosilicate glass, stainless steel or other special materials and alloys.

• Different wiper systems are selected depending on the product properties.

• Floor stand or moveable cart design.
