You have invested a great deal in order to develop a fruit juice beverage of top quality? You want to be sure that this quality is preserved in the manufacturing and filling processes? Then integrate the Krones product deaerator VarioSpin in your manufacturing process. With VarioSpin you make use of a compact vacuum-assisted deaerator which permits highly effective filling processes without the formation of foam at the filling valve.

At a glance

• Deareation tanks with patented swirl inlet
• Output: 7.5 to 60 m3/h
• Recovery and return of flavouring through a Venturi nozzle
• Internal recirculation for a multi-stage deaeration
• Reduced mixing phases for short change-over times and low product losses

1 Gentle product feed

• Patented swirl inlet nozzle, which creates an immediate and even product layer on the inner container wall as soon as the product is coming in
• Turbulent flowing film enables short diffusion paths for the gas bubbles coming from the product 
• The entire tank surface can be used for the deaeration process

2 Individual adjustment of the vacuum pressure

• Vacuum pressure adjusted to the infeed temperature and product properties
• Gentle feed prevents uncontrolled foaming
• Vacuum pressure can be reduced to the point required for high deaeration performance

3 Recovery of flavouring losses

• Recovery of flavouring carry-over in a (multi-stage) condensation step 
• Flavouring return via the Venturi nozzle in the discharging product flow with reliable homogenisation via the product pump
• Avoidance of flavouring concentrate carry-over during the change-over to other beverages via intelligent backflushing processes
• Obtaining important flavouring in the beverage at the respective cooling temperature of the condenser

The right swirl

The dissolved gas can be quickly eliminated from the product with the thin product film upon entry into the deaeration container. And the performance of your filling line remains continually at a high level.

Foam-reduced filling

The deaeration performance benefits from product which is fed in gently and a turbulent surface. Without foaming, the product can be deaerated highly efficiently.

Variable product flow

The technology of the swirl inlet guarantees flexibility in the deaeration performance. You can adjust the product flow at constant deareation rates by up to 50 percent without any dynamic components and high maintenance effort.

Efficient product change-over conditions

Due to the smaller tank volume resulting from the efficient product infeed technology, you can achieve up to 50 percent fewer mixing phases during product change-overs.

Comfortable operation and maintenance

During the operation of the VarioSpin deaeration module, your employees profit from the ergonomically arranged measurement devices and sensors. Furthermore, the small number of seals and components is a clear advantage in daily operation.

Flexible during operational changes

If changes are carried out in your plant, the VarioSpin product deaerator adjusts to them. Since it is modular in design and software concept, the product deaerator can be quickly integrated in new lines or it can be supplemented as a stand-alone solution.
