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 wiper elements. These wipers are pressed to the inner wall of the surface where they produce a thin film with a continuous distribution of liquid to maximize evaporation. The condenser is vertically arranged in the center of the glass evaporator, tempered by liquid flow, to reduce the 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 botanical extracts without decomposition.
The rotating wiper basket is made of stainless steel Aisi 316 Ti and equipped with PTFE (Teflon) roll wipers.
The PRESCOTT 1000 LITE is offered as a complete turnkey system including complete vacuum accessories and three high capacity thermostats to temper feed-vessel, inlet line, evaporator and the condenser including outlet line. The residue outlet is also tempered to prevent solidification of very heavy, waxy residues.
The PRESCOTT 1000 LITE is a system for batch operation and the economical budget friendly alternative for to our fully continuous flagship PRESCOTT 1000, which includes a sophisticated control cabinet including vacuum control system and tempered gear pumps for automatic operation without vacuum interruption.
One of the unique features of the PRESCOTT 1000 LITE are the interchangeable vessels of feed and residue: The residue vessel can be used as feed vessel, which allows to run the second path without any refilling. This eliminates material losses and saves minimum down time compared to all other systems available.
