PRESCOTT 1000 Turn-Key Thin Film Continuous Distillation System

Continuous distillation, a form of distillation, is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams. Distillation is the separation or partial separation of a liquid feed mixture into components or fractions by selective boiling (or evaporation) and condensation. The process produces at least two output fractions. These fractions include at least one volatile distillate fraction, which has boiled and been separately captured as a vapor condensed to a liquid, and practically always a bottoms (or residuum) fraction, which is the least volatile residue that has not been separately captured as a condensed vapor.

PRESCOTT 1000 OVERVIEW

PRESCOTT distillation systemss combine innovation with best-in-class performance, featuring improved borisilicate glass and AISI 316 Ti steel construction. Designed for compounds of high viscosity and molecular weight, this semi-automated system is a complete turn-key solution for continuous distillate production. Optimized for operation at extreme vacuum, the system can reduce the boiling point of thermally sensitive products without decomposition.

Unit also allows for easy cleaning and maintenance due to its signature patent pending hybrid evaporator and easily removable PTFE-coated roller/wiper basket.

Seamlessly integrated design, constructed of both stainless steel and borosilicate glass to provide a semi-automated wiped film distillation solution for continuous material separation. Wiped film distillation is utilized to separate thermally sensitive products under vacuum and offers higher throughputs than traditional bench top short path systems.

The evaporation surface combines the benefits of 316 Ti stainless steel with vertical concentric glass cylinders. These materials form the double mantled molecular still and are heated with circulating thermal fluid. The incoming crude product is spread to a thin film on the inner surface of the evaporator by means of rotating PTFE roller elements. The condenser is vertically arranged in the center of the glass evaporator, also tempered by liquid flow, to reduce the distance vapors must travel and prevent any pressure losses from a large transfer space.

The system includes a dry scroll vacuum pump with additional high-capacity diffusion, vacuum control and 2 vacuum sensors, 3 high capacity thermostats to temper feed-vessel, inlet line, evaporator and the condenser, as well as outlet lines. A deep immersion cooler and enlarged cold trap provide enhanced vacuum performance throughout operation. The units are constructed with only the highest quality components available and fully integrated electrical control cabinets.

Maintenance time on the system is minimized from a virtually tool-less construction and quick-release fasteners. Moreover, transfer loss is essentially eliminated with our vertical platform and proprietary hybrid evaporator design.  Prescott is focused on the ease of operation and minimizing of material losses while simultaneously attaining the highest available throughputs and potencies.
The Prescott 1000 is offered as complete turn-key distillation solution specifically for botanical extracts. We combine years of operational expertise with decades of German manufacturing precision to deliver the highest quality distillation systems with the shortest lead times in the industry.

Entire system built and tested in Germany.
