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
-
