Nozzle Separator SDC 70-.6-003 in 2-Phase Design

Nozzle Separator SDC 70-.6-003 in 2-Phase Design


Starch clarification, Starch concentration, Starch washing, Renewable Resources


This nozzle separator has been designed for continuous starch concentration and clarification. If the bowl is equipped with an additional wash water system also a starch washing takes place. According to customer needs the nozzle separator can be designed in 2-phase design, with or without wash water (SDC 70-76 / SDC 70-06). The product is fed into the machine through a closed-line system.  The separated solids (concentrate) are continuously discharged through nozzles into the concentrate catcher where they flow off under gravity. The clarified liquid(s) is/are pressure-dicharged via centripetal pump(s) through a closed line system. The self-cleaning bowl makes the machine suitable for fully automatic cleaning-in-place. The frame is made of cast iron. The power is transmitted directly to the bowl spindle by a 3-phase AC motor with frequency converter control via a torsionally elastic clutch. Oil lubrication is performed by an external oil lubrication system. An oil filter is fitted in the lube oil feed. All parts coming into contact with the product and ejected solids are made of Cr-Ni-Mo stainless steel, the gaskets are made of rubberelastic materials (elastomers).
