Lecithin is extracted from the raw vegetable oil in the degumming process of an oil mill by means of a separator. The up to 90 °C hot lecithin mixture is transported to a storage tank. The Börger ONIXline pump conveys the mixture with a viscosity of up to 5,000 mPas in a 35 m high tank where it is inserted by means of nozzles. In the process, a pump pressure of approx. 10 bar is created. More or less of the lecithin mixture has to be added depending on the liquid content of the press cake. The pump is operated by a frequency converter. This way, the speed and flow rate can be varied and adapted to the liquid content of the animal feed. The bleaching earth contained in the lecithin mixture is the reason why the medium is abrasive.
