As integration of its sterilization (U.H.T.) and pasteurization (E.S.L. or H.T.S.T.) lines and plants, REDA S.p.A. offers deaeration systems under vacuum for the expulsion of air and gases dissolved in the treated products as micro bubbles.

Special distributors mounted on the device turn the product into a very thin film, which, combined with the negative pressure, allows a perfect dispersion of the air.

With milk-based products the deaerator under vacuum removes the dissolved gases, which could also give an unpleasant odour to the final product.
For products as juices, purées or nectars the device serves to eliminate the oxygen responsible of the product oxidation, which would cause therefore change of colour and loss of nutritional value.
