Aseptic Tank System - Storage of Aseptic Products
APV® Aseptic Tank Systems provide reliable, sterile intermediate storage for liquid foods and beverages between thermal processing and packaging. Designed to integrate seamlessly with UHT processing systems, they maintain product integrity and plant flexibility while supporting continuous, high-volume aseptic food processing.
Aseptic Storage for Flexible, Continuous UHT Processing
APV Aseptic Tank Systems act as a buffer between ultra-high temperature processing and aseptic filling, allowing the line to keep running during downstream interruptions or changeovers. They support smooth operations and maintain sterility even during extended holding periods.
Today’s processors face key challenges:
- Avoiding downtime when packaging equipment is offline
- Maintaining sterility in holding tanks
- Managing product changeovers and cleaning without halting production
- Ensuring consistent product quality during intermediate storage

Theory of Operation
APV Aseptic Tank Systems operate by maintaining a sterile, pressurized environment for processed liquid products between the UHT system and the filling line. After thermal processing, sterile product enters the aseptic tank via a double-seat valve that prevents contamination.
The system typically includes:
- Inlet/Outlet Valves – Ensure sterile transitions and flow control
- Sterile Air Management – Pressurizes the tank using filtered sterile air or nitrogen
- Level Control – Maintains appropriate product volume for downstream operations
- Temperature Monitoring – Preserves quality and stability during hold times
- CIP/SIP Circuits – Automate cleaning and sterilization to maintain hygiene
This controlled system enables continuous aseptic processing even when packaging lines pause or switch.
