Mechanical Engineering Tools

Product Overview

  • The Falling Film Evaporator Automation Control System is built around a Siemens PLC controller + HMI architecture, integrating real-time monitoring and closed-loop control of temperature, pressure, vacuum level, and flow rate.

  • It offers seven basic functional modules — parameter setting, historical curves, pump calibration, data reporting, alarm management, and recipe storage — delivering fully automated operation with guaranteed batch consistency and full process traceability.

  • Upgradeable to 21 CFR Part 11 compliance: supporting digital records and signatures for pharmaceutical applications.

Functional Modules

Main Interface >>>

  • Presents real-time evaporator status through an intuitive process flow diagram with digital instrument panels — all critical process variables at a glance.​

    • Setting Value (SV) vs. Actual Process Value(PV) side-by-side

    • Parameter setting & real-time status of temperature, pressure

Historical Trend Curves >>>

  • A built-in real-time database continuously logs critical variables curves. Supports multi-curve overlay on a single chart — providing a complete data foundation for process optimization and troubleshooting.

    • Historical curves of temperature, vacuum degree, flow rate

    • Zoomable timeline & range selection

Calibration Interface >>>

  • One-touch pump calculation: set values, then press start button— the system auto-calculates the calibrated flow rate, ensuring consistent feed accuracy across batches.

    • Pump calibration of vacuum, transfer speed, transfer volume

    • Clear start/end times and elapsed duration

System Settings >>>

  • Centralized system settings for time, user access, and data security — tiered permissions prevent unauthorized operation, one-click cleanup safely frees storage.

    • Language switching for global deployment

    • System time setting

    • Tiered access & account management

    • Data cleanup

Data Reports >>>

  • Automatic data logging, storage, and batch report generation. Direct USB export is supported, meeting QA audit and compliance archiving needs.

    • Structured reports include date/time, temperature, vacuum level and flow rate statistics

    • Dual-format output (CSV, PDF)

Alarm Management >>>

  • Users can freely set upper and lower alarm thresholds. All alarm events are automatically logged and timestamp-archived, providing an event-chain for maintenance and diagnostics.

    • Configurable alarm thresholds for temperature, vacuum level, flow rate and other critical parameters

    • Audible + visual dual alarm

Recipe Management >>>

  • Supports up to 24 independent recipes and one-touch recall, ensuring process consistency and reducing batch changeover time.

    • Four core process parameters: feed rate, heating temperature, cooling temperature and vacuum level
