UIC KD10 Automated Pilot-Scale Stainless Steel Short-Path (Molecular) Distillation System

Overview

The UIC KD10 Automated Pilot-Scale Stainless Steel Short-Path (Molecular) Distillation System is an engineered solution for high-vacuum, low-temperature thermal separation of thermally sensitive, high-boiling-point, or viscous compounds. Operating on the principle of short-path molecular distillation—where mean free path of vapor molecules exceeds the distance between evaporator and condenser surfaces—the system enables separation based on differences in molecular weight and vapor pressure under ultra-high vacuum (typically <0.001 mbar), minimizing thermal degradation. Designed for pilot-scale process development and small-batch production, the KD10 bridges laboratory feasibility studies and industrial scale-up, supporting R&D laboratories, contract manufacturing organizations (CMOs), and fine chemical producers requiring reproducible, scalable purification data under GMP-aligned conditions.

Key Features

• Full stainless steel 316L construction throughout evaporator body, feed lines, wiper assembly, and condenser housing—ensuring corrosion resistance, cleanability, and compliance with pharmaceutical-grade material contact requirements.
• Integrated PLC-controlled automation platform with HMI touchscreen interface, enabling pre-programmed distillation sequences, real-time parameter logging (temperature, pressure, feed rate, wiper speed), and automated fraction switching between three independently controlled collection vessels.
• High-efficiency rotating wiper system with adjustable speed (0–300 rpm) and PTFE-coated blades, ensuring uniform thin-film formation and consistent residence time across the 0.1 m² heated evaporation surface.
• Water-cooled internal condenser with 0.088 m² active surface area, positioned concentrically within the evaporator cylinder to minimize vapor path length (<30 mm) and maximize condensation efficiency at sub-ambient temperatures.
• Integrated vacuum compatibility with standard KF-40 and KF-50 flanges; designed for seamless integration with primary vacuum pumps (e.g., dual-stage rotary vane + secondary turbomolecular pump) and optional cold traps.
• Modular feed system with precision mass-flow controlled dosing (5–15 kg/h range), temperature-regulated pre-heater zone, and optional integrated degassing unit for volatile removal prior to film formation.

Sample Compatibility & Compliance

The KD10 accommodates a broad spectrum of heat-labile and high-molecular-weight feedstocks, including natural extracts (e.g., fish oil concentrates, tocopherols, astaxanthin), synthetic intermediates (e.g., polyunsaturated fatty acid esters, silicone oligomers), pharmaceutical actives (e.g., vitamin A palmitate, prostaglandins), and specialty polymers (e.g., polylactic acid oligomers). All wetted parts meet ASTM A240 and EN 10088-1 standards for stainless steel 316L. The system supports IQ/OQ documentation packages and is configurable for 21 CFR Part 11-compliant electronic records when paired with UIC’s validated SCADA software module. It conforms to ISO 9001 design practices and supports GLP audit readiness through full traceability of setpoints, alarms, and operational logs.

Software & Data Management

UIC’s proprietary DistillSoft™ v4.2 provides centralized control, real-time monitoring, and secure data handling. The software features multi-user role-based access control, automatic generation of CSV/Excel-compatible process reports, and timestamped audit trails for all critical parameters—including vacuum level (capacitance manometer readout), evaporator wall temperature (PT100, ±0.3 °C accuracy), condenser coolant temperature, and feed flow rate. Optional data export modules support direct integration into LIMS environments via OPC UA or Modbus TCP protocols. All configuration changes and manual interventions are logged with user ID, timestamp, and reason code—meeting ALCOA+ principles for data integrity.

Applications

• Purification of omega-3 concentrates (EPA/DHA ethyl esters) from crude fish oil hydrolysates, achieving >95% purity with minimal cis-trans isomerization.
• Deodorization and monoglyceride removal from distilled monoglyceride batches used in food emulsifier production.
• Isolation of phytosterol fractions from tall oil pitch under <0.0005 mbar vacuum and 120–180 °C evaporator temperature.
• Recovery and concentration of fragrance volatiles (e.g., ionones, damascones) from botanical distillates without thermal scorching.
• Preparative-scale separation of polymerization inhibitors (e.g., BHT, hydroquinone derivatives) from reactive monomer streams prior to storage.

FAQ

What vacuum level is required for optimal operation of the KD10?
The system is engineered for stable operation at ≤0.001 mbar (≤1×10⁻³ mbar); performance validation is conducted at ≤5×10⁻⁴ mbar using calibrated capacitance manometers.
Can the KD10 be validated for GMP manufacturing use?
Yes—UIC provides IQ/OQ protocol templates, calibration certificates for all critical sensors, and optional PQ support documentation aligned with ICH Q5, Q7, and Annex 15 guidelines.
Is remote monitoring supported?
Standard Ethernet connectivity enables secure remote access via VPN-configured network infrastructure; full remote control requires additional cybersecurity assessment per site policy.
What maintenance intervals are recommended for the wiper mechanism?
Wiper blade inspection is advised every 200 operational hours; full mechanical service—including bearing and seal replacement—is scheduled at 2,000-hour intervals or per usage log analysis.
Does the system include degassing capability?
The base KD10 configuration does not include an integrated degassing unit; however, the KD10-D variant adds a vacuum-assisted feed degasser upstream of the evaporator, reducing dissolved gas entrainment in the thin film.
