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.
- With Krones tubular heat exchangers, developed by Krones process equipment experts
- In-house laboratory for product analysis
- Perfectly matched with the Krones aseptic fillers
Filling and preservation of milk – Various treatment procedures
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
Module for media supply
- Uncoupling of downstream process for stable production conditions
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 with VarioAsept D
Service module
- Energy supply for product heat exchanger
- Electrical and pneumatic controller with MCC and Krones HMI
Flexible heating options
Direct heating with the VarioAsept D
Product range: Dairy products, Plant-based drinks, Sensitive products

VarioAsept D
Module for steam injection or infusion
Module for media supply
Uncoupling of downstream process for stable production conditions
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
Procedure 1: injection
- Steam is injected directly into the product through the adjustable nozzle.
Scope
- Low-viscose products
Vorteile
- Compact module design
- Significantly lower CAPEX costs (compared to infusion)
Procedure 2: infusion
- The product is fed into the infusion chamber from above.
- It then drops through the steam-filled chamber where it heats up to the required heating temperature.
- The product does not come into contact with the hot stainless steel surface of the vessel. The conical end of the chamber itself is cooled.
- Deaeration is performed during the heating process..
Scope
- Products of medium or high viscosity and plant-based drinks
- Milk and mixed milk beverages
Advantages
- Long production times possible
- Highly flexible technology for sophisticated products with high demands on quality
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.
