Different process variants for different needs.
GEA offers several different process variants of the deaeration system that covers the entire product range – from low to high viscosity products, from small particles up to fruit purées with high solid particle content.
Deaeration - one technology for many purposes and products
- Deaeration system with gentle tangential product inflow into the pressure vessel
This method has the lowest shear rate and is applicable for all recipes. It ca be used for both aseptic and for non-aseptic deaeration.
- Deaeration system with product inflow into the pressure vessel from the top
This variant is mainly used for low-viscosity products with high gas content, and offers the highest deaeration effect for this application. The product enters centrally from the top via a special, adjustable cascade valve. This effectively increases the product surface and ensures an optimum deaeration result.
- Deaeration system with product inflow from the bottom
This variant is mainly intended for products with low medium viscosity. After the product entered the pressure vessel from the bottom it is applied evenly and uniformly to the product surface in very thin layers by mushroom-shaped product distributor. The layers of product are vertically stable. That ensures that they do not mix with each other, meaning that the product that is filled first also leaves the deaerator first.
The product distributor is flexibly mounted on the product supply pipe to ensure that the product flows gently and smoothly into the tank.
