A sugar beet manufacturer was looking for a high performance pump to transfer cooked sugar beet. The pump needed to be resistant to solids and able to convey high-temperature media. It was essential for the manufacturer to have a pump with high reliability. The customer opted for a Boerger Rotary Lobe Pump in stainless steel.
Before the sugar beet is transferred to two stainless steel tanks by an auger unit, soil and other impurities are removed. The beet is heated to 105 degrees for approx. 7-8 hours in the stainless steel tanks (excess pressure 0.5 bar – so that it cannot start to boil). After the cooking process, the beet slurry containing large pieces of beet is fed to the Boerger Rotary Lobe Pump through a special auger.
The Boerger pump conveys the unpurified beet slurry into a tank. Then a two-phase decanter is fed by another pump and pure beet substrate is formed.
