DSN Unité Didactique d'Écremage du Lait

The Teaching Cream Separator, "DSN", allows the study of the separation of a dense phase liquid from a lighter phase liquid, in particular the separation of the cream from the milk in a disk stack centrifuge.

The system is mounted on a table base on which the integral elements of the unit are located.

The milk supply tank is located over the centrifuge and can be filled in continuously.

The separating bucket consists of a vertical rotation axis and discs or conical plates. They are arranged one on top of another in an inverted manner and separated by very little distance. In addition, the discs have small holes that allow the flow of material through them.

This set of discs is surrounded by a casing and sealed by a rubber gasket to avoid possible losses. All these elements are contained in a polypropylene bucket or vessel that includes two outlet ducts, one for the cream and another for the skimmed milk.

The motor is directly coupled to the separator vessel and vertically mounted in a casing. It makes the plates rotate at high speed and, therefore, it is the element that creates the centrifugal force.

Besides, the unit has a control panel that contains the speed regulator. It allows to control and vary the turning speed of the motor, so that the density of the cream to be obtained is controlled.
