Sterile tank system for aseptic processing
Optimize your production with aseptic tank systems that ensure sterile storage and precise buffering for liquids, essential for maintaining quality and safety across high-stakes beverage lines.

Stores and Buffers Aseptic Beverages
The VarioStore tank system from Krones is engineered for dairy and beverage manufacturers who require reliable aseptic storage and buffering. This system features vacuum-tight tanks with capacities ranging from 20 to 50 m³ and offers versions with magnetic or bar agitators for effective product homogenization. Integrating seamlessly into continuous production lines, it supports automated operations with its own PLC or integration into thermal treatment systems. The VarioStore system utilizes a robust valve manifold with sterile product valves and steam locks, offering up to three process gases for maintaining product pressure. Enhanced with a redundant 0.2 μm sterile gas filtration system, coupled with inline steam sterilization, it ensures contamination-free handling of milk, plant-based alternatives, juices, and more. Its efficient cooling and homogenization processes are adaptable, providing energy-efficient solutions with water return cooling options, contributing to overall operational efficiency and safety in food and beverage production environments.
