BDB 104 Solids-retaining centrifugal separator for biodiesel processing Applications The BDB 104 is specifically designed for use in the production of biodiesel and is particularly suitable for water removal from methylester in water washing stages. Standard design The solids-retaining separator comprises a frame with a horizontal drive shaft, worm gear and a vertical bowl spindle in its lower part. The worm gear is placed in an oil bath. The bowl is fixed on the top of the spindle inside the space formed by the upper part of the frame and the frame hood, which also carries the feed and discharge systems. The frame hood is hinged to enable easy access for cleaning the bowl, which is of the solid wall disc type. The machine is electrically safe and approved for ATEX category 3 Basic equipment - Methylester inlet device. - Methylester outlet device with sight glass. - Water outlet spout. - Liquid seal inlet. - Set of gravity discs. - Revolution indicator. - Set of resilient mountings. Options The centrifuge can be ordered either with or without a built-in pump for both feed and discharge liquids. Optional extras Cover-interlock kit to eliminate the risk of starting the centrifuge unless it is properly assembled. Set of tools. Different service kits are available for maintenance of the centrifuge. Stand-alone pumps for both feed and discharge. Technical documentation Complete information and documentation accompany each separator delivery. The Instruction Book provides detailed operating instructions and advice on obtaining optimal separation. The Maintenance and Repair Manual describes dismantling and reassembly of the separator. The Spare Parts Catalogue facilitates the ordering of spare parts.

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).
