Vertical mixer and vertical dryer

Cylindrical mixer / cylindrical dryer

AVA cylindrical mixers / cylindrical dryers from the HVM range are available as two variants:

Compared to other vertical mixing systems, the HVM range achieves higher mixing efficiency with a considerable reduced contruction height. The HVM cylindrical mixer / cylindrical dryer combines the advantages of a conical vessel, e.g. regarding to an optimum discharge, with the optimized overall height, in order to fit into existing buildings etc.

The rotating mixing helix (available as a single helix or as a MITRAVA double helix) conveyes the product upwards, along the outer wall of the vessel. From here, it drops down into the shaft area at the centre of the vessel and thus into the mixing process again. The drive and bearing are located outside the vessel. A contamination of the product with oil or lubricating grease, which is a common problem within other mixing systems, is excluded by this technology.

The cylindrical mixers in the HVM range are emptied on bottom-side with the agitator running. This ensures a residueless discharge, guaranteed in particular with the conical cone-shaped base. Optimum accessibility is assured due to the large inspection doors in the cylindrical area of the vessel, whilst easy cleaning is automatically effected by the integrated CIP nozzles.

In the HVM-dryer variant the vessel wall and / or agitator are fully heated, meaning that an above-average thermal transfer coefficient is achieved. The configuration comprising a cylindrical dryer with flat base is particularly efficient in terms of drying behaviour.
