Solids-retaining centrifugal separator for biodiesel processing - 2

Operating principles The feed is introduced to the rotating centrifuge bowl from the top (1) and is accelerated in a distributor (2) before entering the disc stack (3). It is between the discs that the separation takes place. The water and the heavier solids are forced towards the bowl wall where the solids accumulate and the water proceeds over the top disc (4) to an open outlet (5). The methylester moves towards the center and leaves the bowl through an open outlet (6).
