Microbiological safety for your products
UHT process precisely tailored to milk products
In the Krones Group, particular focus is on milk –the white gold. Particularly the topic of preservation plays a significant role –as the process is not only governed by the highest hygiene requirements, the product itself must also be treated with extreme care. The VarioAsept M UHT system from Krones meets precisely these requirements.
At a glance
- Especially designed for use in the dairy industry
- Output range: Between 3,500 and 60,000 litres per hour
- Proven design which
- meets the highest hygiene requirements of dairy-processing companies.
- treats the product extremely gently.

Components of the modular component system

VarioStore tank system for aseptic lines
−Vacuum-sealed and pressurised up to 6 bar
−Fully aseptic, automatic valve manifold between UHT system and buffer tank
−With integrated system for sterile gas filtration
Krones VarioSpin product deaerator
Deaeration with patented swirl infeed nozzle:
−Ensures that gas bubbles will quickly escape from the product
−Reduces oxidative impact such as loss of vitamins or discolouration of juices
Heat exchanger
Depending on product requirements:
−Plate heat exchanger
−Tubular heat exchanger with cross-corrugated tubes for less thermal impact
Alternatively: direct heating
Service module
−Energy supply for product heat exchanger
−Electrical and pneumatic controller with MCC and Krones HMI
Benefits to you
Temperature control by choice
The heating process can be optionally controlled with a precise F-value or temperature control system, or through flexible PU regulation.
Long production times
Aseptic intermediate cleaning with caustic at the product treatment temperature of the heat exchanger can be carried out without interrupting the aseptic filler production as the filler is supplied by the aseptic buffer tank.
Low product losses
A rework tank for mixing phases, the integrated buffer tank and automatic output regulation in the event of production fluctuations in upstream and downstream systems contribute to high cost effectiveness.
Aseptic product change-over
Water flushing within 35 minutes between the last and the first bottle (for Krones standard layout) provides high flexibility for production.
Gentle product treatment
The thermal and oxidative stress on your product will be reduced because specially designed inner tubes in the selective heater and chiller sections can be heated and chilled again very quickly.
