UDCB 連続蒸留装置



The Distillation Unit, "UDCB", designed by EDIBON, is a powerful laboratory tool for the study of variables affecting the distillation process. The student can investigate the principles that govern the transfer of matter and energy, as well as determine the optimum operating point for carrying out a large number of separations.




The Continuous Distillation Unit, "UDCB", is formed by a boiler, on which different types of columns can be adapted (plate columns and Raschig columns). An eight plate column, a reflux system, a tank for distillation, a vacuum pump and a feeding pump (for continuous feeding) are included.

The steam reaching the head of the column is sent to a total condenser. The cooling water flow going through the condenser can be adjusted and is indicated in a flow meter. Distillation can be carried out at low pressures with the help of an adjustable vacuum pump. The load loss in the column can be measured with a pressure meter.

The column can work both continuously and discontinuously.

For proceeding to continuous feeding, a pump that can inject the substance directly into the boiler or in any of the plates is available.

The temperatures of the system are measured through sensors placed in strategic positions.
