What is the difference between batch and continuous processing using a vacuum de-aerator?
Batch vs. Continuous Vacuum De-Aeration — Key Points and Comparison
Key Points
- Capacity difference: Batch process 50–500 L per cycle; continuous processing up to 5,000 kg/hour throughput
- Standards: GMP Annex 1 (2022) for pharmaceutical processes + EHEDG Class II for food + ATEX 2014/34/EU
- HECHT product: ProClean Conveyor with integrated vacuum de-aeration for continuous API production
- Applications: Pharmaceuticals (batch-for-batch traceability), food (continuous production FSMA), chemicals (REACH)
- ROI: Continuous processing delivers 25–40% higher OEE versus batch mode at volumes above 500 kg/hour

FAQ — Batch vs. Continuous Vacuum De-Aerator Processing
When is batch processing with a vacuum de-aerator the right choice?
Batch processing is optimal for products requiring batch-for-batch GMP traceability (ICH Q7, GMP Annex 1), in multi-product facilities with frequent product changeovers, or for small volumes under 200 kg per production run. Hecht Technology recommends a batch de-aerator when complete batch segregation is demonstrably necessary for API production.
Which vacuum de-aerator system is suitable for continuous production exceeding 1,000 kg/hour?
For continuous processing above 1,000 kg/hour, a through-flow de-aerator with integrated vacuum pump and automatic pressure control is the most efficient choice. Hecht Technology's ProClean Conveyor is available with continuous de-aeration function per EHEDG Class II and ATEX Zone 21 certification for explosive production environments.
What is the energy consumption of a continuous vacuum de-aerator versus batch processing?
Continuous vacuum de-aerators consume 15–30% less energy per kilogram of product compared to batch systems at equal production capacity, because the vacuum pump operates at constant low power. Hecht Technology implements IE4 motors and VFD control to minimize energy consumption per ISO 14001 and CSRD reporting obligations.
