The extraction process of sugar from sugar beet has a high impact on the sugar yield and thus income. It is important to control the leaching of the raw material as efficiently as possible in order to achieve the best possible output with maximum capacity. From extraction towers to DDS troughs to rotating diffusion drums, ANDRITZ is your competent partner. In most cases, the extraction process is the bottleneck of the entire production chain. Capacity can be increased through the use of optimised screens. We can also offer you optimised solutions that simplify the cleaning of screens, for example. We would be happy to discuss your system together and identify optimisation potential for the maximum sugar yield.
DDS screen trays are used during extraction. They are used to retain the pulp. We can offer you DDS screens in punched, drilled and slot-milled versions. The retention of the pulp and additionally the capacity can be increased by the choice of perforation.

Screens for RT diffusion drums can be supplied as a cost-effective, punched version or as an optimised, drilled version. With the drilled version, thicker and more wear resistant materials can be machined. In addition, using this method, the screening area can be increased, increasing the capacity significantly.
RT diffusion screen
In many cases, maximum capacity in the extraction process has already been achieved and can only be expanded by commissioning a further tower. Andritz manufactures optimised screens as an alternative solution to this, which achieve an increase in throughput. The higher open area and smaller screen openings retain the pulp more efficiently and significantly increase its capacity. Optimised opening geometries reduce the risk of blockage of the screens by small stones or pulp and simplify cleaning.
