Anyan AYAN-F80 Short-Path Molecular Distillation System

Overview

The Anyan AYAN-F80 Short-Path Molecular Distillation System is a high-vacuum, low-temperature separation platform engineered for thermal-sensitive, high-boiling-point, and non-volatile compounds. Operating under absolute pressures below 10 Pa, it exploits the fundamental principle of molecular distillation—where the mean free path of vapor molecules exceeds the physical distance between the heated evaporating surface and the cooled condensing surface. This enables separation based on differences in molecular weight, volatility, and vapor pressure—not boiling point—making it uniquely suited for thermolabile substances that decompose under conventional distillation conditions. Unlike fractional or vacuum distillation, molecular distillation occurs in the free-molecular flow regime, minimizing residence time at elevated temperatures (<200 °C max heating surface temperature) and eliminating carryover or entrainment. The AYAN-F80 is designed for bench-scale R&D, process development, and small-batch purification in regulated laboratory environments.

Key Features

• Stainless steel (316L) evaporator body with precision-ground 80 mm internal diameter cylindrical heating surface, ensuring uniform thermal distribution and minimal dead volume.
• High-efficiency internal condenser with 0.15 m² active cooling area, integrated with dual-stage PTFE-coated cold traps to maintain stable sub-zero surface temperatures.
• Two independently controllable collection flasks (light and heavy fractions), each rated for up to 1 L capacity and equipped with quick-release ground-glass joints and vacuum-tight stopcocks.
• Variable-speed scraper mechanism (0–450 rpm) with PTFE-coated blades, optimized for viscous feeds and film renewal control across shear-sensitive materials.
• Integrated digital temperature controller (PID) with dual thermocouple inputs—one for evaporator surface, one for condenser—accurate to ±0.5 °C over 0–200 °C range.
• Backlit vacuum gauge and analog/digital interface supporting real-time monitoring of system pressure (range: 0.1–100 Pa), compatible with external vacuum controllers and turbo-molecular pump systems.

Sample Compatibility & Compliance

The AYAN-F80 accommodates feedstocks ranging from low-viscosity oils (e.g., fish oil, essential oils) to highly viscous polymer intermediates and waxy biolipids (e.g., lanolin, vitamin E acetate). It supports batch and semi-continuous operation with feed rates adjustable between 0.5–4.0 L/h via peristaltic or syringe pump integration. All wetted parts comply with USP Class VI and FDA 21 CFR 177.2600 standards for food-contact and pharmaceutical use. The system architecture aligns with GLP documentation requirements: temperature and vacuum logs can be exported in CSV format for audit trails. While not certified to ISO/IEC 17025, its design conforms to ASTM D2892 (standard test method for atmospheric distillation of petroleum products) and ISO 661 (animal and vegetable fats and oils—preparation of test sample), serving as a validated platform for method development prior to scale-up.

Software & Data Management

The AYAN-F80 operates via a standalone microprocessor-based control panel with non-volatile memory for up to 10 user-defined protocols. No proprietary software is required; however, RS-485/Modbus RTU output enables integration with LabVIEW, MATLAB, or SCADA systems for automated data acquisition. Vacuum, surface temperature, condenser temperature, and runtime are timestamped and stored locally for ≥30 days. Audit-ready data export includes ISO 8601-compliant timestamps, operator ID fields (via optional RFID badge reader), and configurable alarm thresholds—supporting 21 CFR Part 11 readiness when deployed with validated electronic signature workflows.

Applications

• Fine Chemicals: Purification of fragrance esters, monoglycerides, and epoxy diluents; isolation of high-purity phytosterols and squalene from plant extracts.
• Pharmaceuticals: Solvent-free concentration of omega-3 fatty acid ethyl esters; recovery of heat-labile vitamins (A, E, K1); preparation of chiral intermediates without racemization.
• Materials Science: Deacidification and deodorization of bio-based lubricants; fractionation of polymeric oligomers (e.g., polycaprolactone, polyethylene glycol derivatives); removal of catalyst residues from silicone precursors.
• Food & Nutraceuticals: Molecular refinement of krill oil phospholipids; separation of tocopherol homologs; decolorization and deodorization of palm olein without stripping natural antioxidants.

FAQ

What vacuum level is required for optimal operation?
The system achieves full molecular regime performance below 10 Pa; operation at ≤1 Pa is recommended for highest separation efficiency with thermally fragile compounds.
Can the AYAN-F80 handle solid-containing or crystallizing feeds?
Pre-filtration (≤5 µm) is mandatory. For feeds prone to crystallization (e.g., fatty acid mixtures), jacketed feed lines and inline heated filters are advised to prevent clogging.
Is validation support available for GMP environments?
Anyan provides IQ/OQ documentation templates compliant with ASTM E2500 and EU Annex 15. Full PQ support requires site-specific protocol development with qualified third-party vendors.
What maintenance intervals are recommended?
Daily: Visual inspection of scraper blade wear and O-ring integrity. Quarterly: Calibration of temperature sensors and vacuum transducer against NIST-traceable references. Annually: Replacement of diffusion pump oil (if used) and full gasket set.
Does the system include corrosion-resistant components for acidic feeds?
Standard configuration uses 316L stainless steel and PTFE seals. For strongly acidic media (e.g., crude tall oil), optional Hastelloy C-276 evaporator liners and fluorosilicone gaskets are available upon request.
