For decades, BMA is recognised as the world leader in developing, designing and constructing continuously operating vertical sugar beet extraction plants. BMA's sugar beet extraction plants are among the most efficient plants on the market, both in terms of technology and heat economy.
The extraction tower, now without bottom screens, but with side screens only, offers substantial advantages with regard to reliability, minimisation of infections, maintenance and repairs. This new concept offers an extended range and allows BMA extraction plants to reach beet slice rates of up to 17,000 mt/d in one single unit.
BMA's continuously operating vertical BMA extraction plants are employed for extracting sugar from beet cossettes. Processing the cossettes through a countercurrent cossette mixer and an extraction tower yields a raw juice characterised by high purity, high dry substance content and low temperature. Sterile operation, without air contact, minimises infections and sugar losses.
The BMA beet extraction plant has two main components accomplishing different technological tasks:
- Countercurrent cossette mixer for thermal denaturation of the cells, heat exchange between incoming cossettes and outgoing juice, and defoaming.
- Extraction tower for solid/liquid extraction of sucrose from the beet cells by the countercurrent principle.
Both components - countercurrent cossette mixer and extraction tower - are interconnected by a piping system and pumps and thus operate as one single unit.
