Dinnissen is developing by a mix of innovations
Dinnissen has broadened the deployability of its mixers, thanks to a mix of innovations.
The mixers have been further improved in several areas, and, moreover, they explicitly consider the role of the mixer in the overall operation. That is why the validation of mixing processes have now been added to their service.
The desire for constant innovation has recently led to the introduction of the ’Improved D-Topline’, a model based on the familiar Pegasus double-axle paddle mixer. The geometry of the installation is modified in such a way that the upper sides of the mixing chamber lean in towards each other, resulting in a drop shape. The negative angle of inclination in the upper side of the mixing chamber reduces the risk of product adhesion. In addition, the ’Improved D-Topline ”can be equipped with an additional hatch (’front hedge’) on the front. This feature makes it much easier to inspect or clean the mixer. In some cases, thanks to this hatch, a version can be offered where the paddle axle assembly can be driven entirely from the mixing chamber.
Furthermore, the ‘Improved D-Topline’ is provided with a divisible shaft seal, allowing the installation to be CIP-cleanable.
Dinnissen is at an advanced stage of optimising high-shear applications in the mixing process, which are also based on the Pegasus mixing principle. There are applications in which powders require a greater frictional force in order to obtain a homogeneous product. A change in the paddle configuration ensures that the new high shear process applies the necessary energy to the product, but without sacrificing the typical advantages of the Pegasus mixer.
Yet another development is the introduction of an explosion-proof mixer (Atex-zone 20 internal), suitable for processing materials in which the Kst- and LEL-values are within a fixed range. This mixer was subject to a risk assessment and received a type approval for the entire Pegasus mixer range from an independent Notified Body.
The ’All in one’ concept is Dinnissen’s response to the demand for fully integrated process lines. An example is the mixing line which has recently been shipped to a customer in the United States. This consists of a skid comprising a docking system for vessels which can be deposited into the mixer dust-free, which can then move the mixer up and down to mix and fill the same vessel again. The great advantage of the ’All in one’ concept is that the various components are perfectly matched to each other. This means that a consistently high-quality product can be guaranteed. There is no segregation of the product, moreover the process is completely dust-free and explosion-proof.
