Krones VarioSpin fruit juice deaerator
Krones’ VarioSpin deaerates fruit juices before bottling.
During deaeration, it is important to form a maximally large and turbulent surface while also ensuring thin layers, so as to minimise the diffusion paths of the gases concerned. At the same time, the mechanical stress on the products needs to be kept as low as possible, so as to restrict foaming. The deaerator has a swirl inlet, designed to gently pass the product along the tank’s walls as soon as it comes into contact with the tank’s cover. Due to the discharge velocity and the adhesive force involved, the juice forms a very thin film over the tank’s walls.
Utilising the tank’s entire surface area, including the cover, enables the tank’s volume to be reduced by more than a third. The design thereby saves space and energy as the lesser volume can be managed by a smaller vacuum pump.
