Automation Bottling DosaFlex aseptic container station Krones

The new DosaFlex from Krones is an aseptic container station for beverages with a solids content.

For the producers of fruit beverages with a solids content like pulp or fruit chunks, a new, elegant, affordable option is now available for aseptic handling of solids.

Krones has developed the DosaFlex aseptic container station for product-friendly dosing of aseptic components in finished beverages with a solids content.

Made by first-time provision of product components with an increased concentration of solids in aseptic containers – it is an option preferred for products featuring aromas and concentrates.

The aseptic containers can, if so desired, be pressurized with an overlay of sterile air or nitrogen to prevent recontamination or absorption of unwanted substances such as oxygen.

For continuous operation, two container connections can be used alternately. To ensure fast container change-overs, the connections are sterilized with steam before the product path is opened.

In the single-flow process, hitherto compounds with a solids content have been non-aseptically blended before the beverage processing section and then heated up together with the fruit-juice content in a UHT (ultra-high-temperature) system. The disadvantage here is that the liquid content also has to be heated up for significantly longer than necessary, with a resultant impairment of the quality.

The newly developed DosaFlex aseptic container station, with its attractive price-performance ratio and its minimized footprint, is also particularly suitable for beverage producers who want to try out new beverages with a solids content on test markets.

The container station is integrated between the units for continuous product treatment and the filler. The finished beverage is blended using controlled dosing in a double-seat valve with an adjacent vapor seal, designed to cope with aseptic processes. For low-acid products, a vapor seal is additionally provided in the condensate drain, so as to ensure a sterile production process even with sensitive products.

The rate of damage to particles that are larger than 3 x 3 x 3 millimeters is below five per cent, while the dosing accuracy lies at +/-0.3 per cent of the dosing quantity involved: both of these figures are significantly lower than those encountered in classical single-flow processes.

The aseptic container station scores highly in terms of eco-compatibility, too: it bears the Krones enviro seal for energy- and media-efficiency.
