Wiped thin film short path distillation system for botanical applications.

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 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 centre of the glass evaporator, tempered by liquid flow, to reduce the distance for the vapours 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 like botanical extracts without decomposition.

The rotating wiper basket is made of stainless steel AISI 316 and equipped with PTFE (Teflon) roll wipers.

SP 1000 CC is offered as a turn-key system including complete vacuum accessories, three high capacity thermostats to temper feed-vessel, inlet line, evaporator and the condenser including outlet line and fully tempered, vacuum tight, dosing and discharge pumps The residue outlet is tempered by an electrical heating circuit to prevent solidification of very heavy, waxy residues.
