Pilot-Scale Fractional Distillation System

Capacity: 1–200L

FDG-J Series Pilot-Scale Fractional Distillation System

FDG-J Series is a high-performance pilot-scale distillation system designed for process scale-up, pilot trials, and small-batch production.

 

With capacities from 1L to 200L, it delivers industrial-grade separation efficiency while maintaining the precision required for critical applications in pharmaceuticals, fine chemicals, and essential oil extraction.

Key Facts

​​​

  • Capacity: 1–200L

  • Temperature Control: Jacketed heating (RT to 250°C)

  • High-Efficiency Columns: 1m standard (30/35/40mm), 10-15 TP/section (customizable)

  • Precision Stirring: 50–600 rpm (AC motor + PTFE impellers)

  • Custom Options: Column type, packing materials, etc.

Features

  • Ideal For: Process scale-up, pilot trials, and small production batches.

  • Jacketed Heating System: Features a fluid-circulating jacket for uniform heating, RT to 250℃ (usually ≤200℃).

  • Efficient Mixing: High-torque AC motor with PTFE stirrer blades to prevent bumping.

  • Easy Cleaning: Discharge valve with no-dead-space design ensuresno residue.

  • Chemical Resistance: Borosilicate 3.3 glass + PTFE components withstand acids/alkalies/organic solvents

  • Visual Monitoring: Full process visibility enables real-time observation of vapor/liquid flow and packing performance.

  • Vacuum/Atmospheric Operation:  Achieves ≤50Pa vacuum for gentle processing of heat-sensitive materials like essential oils.

  • Modular Columns: Standard column diameters (30/35/40mm) and 1m height, customizable lengths available.

  • Packing Versatility: Compatible with θ-rings, Raschig rings, structured packings, and other advanced fillings.

  • Stirring Precision: High-torque AC motor with PTFE impellers and digital speed control prevents bumping.

  • Easy Cleaning: Smooth non-stick surfaces and drain valves minimize cross-contamination risks.

  • Precision Control: Optional vacuum controller for stable pressure regulation.
