In cooperation with specialist TAV Ingenieria, Moba offers a technology that focuses on achieving higher quality dried egg products: a multistage vertical drying system. What separates this technology from the traditional method that uses a horizontal dryer is that the spraying of the liquid happens at the top of a vertical tower.
Such a vertical tower system has many benefits compared to a traditional system. One of the most important is that this way of spray drying creates a superior product at a lower cost.
The first stage is similar to the traditional system: The hot air blows through the spray particles and picks up the moisture, creating the powder. The second stage is that – because of the vertical tower – the fine particles can be re-injected at the top of the chamber. These fine particles agglomerate with the just-formed particles. The final product will rehydrate much quicker than traditional powder, saving the end-user valuable time. Finally, the dried particles descend to the bottom of the tower system, where the static fluid bed blows air at a lower temperature from the bottom. This will create much better flowability to the powders and also will avoid caking of the more fatty products, such as whole-egg and yolk powder. Plus, the use of this system allows final drying at a much lower temperature, so not only a better product is created, but it also saves energy.
Using a vertical tower will also enable you to clean the system automatically. Instead of cleaning the chamber manually, a vertical tower is CIP-cleanable. This makes switching from creating egg-white powder to creating powdered yolk or whole-egg products much easier.
