Sterile tank system for aseptic processing
In aseptic processing, maintaining sterility and product quality during intermediate storage is vital. Challenges such as product contamination and inconsistent homogenization can disrupt production flows and impact product integrity.

Ensures sterile and effective product storage
The VarioStore tank system from Krones is a high-quality solution for aseptic product storage and buffering. These vacuum-tight tanks are available in volumes between 20 and 50 m³. Equipped with a valve manifold, aseptic valves, and sterile steam locks, the system ensures product safety. The tank options include models with or without agitators, and can handle up to three process gases for pressure control. Sterile gas filtration is achieved through redundant 0.2 μm filters accompanied by inline steam sterilization. Content display in the aseptic version uses capillary differential pressure measurement, ensuring precise monitoring. The system can be configured as an independent aseptic buffer tank with its own PLC or integrated into a thermal product treatment setup.
