Seamlessly integrated design, constructed of both stainless steel and borosilicate glass to provide a semi-automated wiped thin film short path distillation solution for separation with continuous operation.
The short path distillation system is designed for distillation of thermally sensitive products under vacuum. The system is used for organic products of thermic instability, high molecular weight and high viscosity at operating temperatures.
The evaporation surface consists of a vertical glass cylinder, double mantled and heated by circulating thermal oil. The product is being spread to a thin film on the inner surface of the evaporator by means of rotating PTFE roller elements. These wipers are being pressed to the inner wall of the surface where they produce a thin film with a continuous distribution of the liquid film. The condenser is vertically arranged in the center of the glass evaporator, tempered by liquid flow, to reduce distance for the vapors to prevent any pressure drop by huge transfer space. This technology enables the operation at extreme high vacuum to reduce the boiling point of thermal sensitive products without decomposition.
For the optimization of the evaporation process, the type of rollers/wipers, as well as the speed of the rotation, can be adjusted to the viscosity of the product to be evaporated. The system includes a controller for vacuum, temperature, power supply for vacuum pump, thermostat and high speed of wiper motor.
The rotating wiper basket is made of stainless steel Aisi 316 Ti and equipped with round, centrifugal PTFE (Teflon) rollers/wipers. The cleaning of the evaporator is very simple due to easily removable fasteners.
