Molecular distillation units - Import export

Since 2020, Stella has been offering the services of an industrial molecular distillation unit entirely dedicated to external customers. With its 4 tanks of 15m3 each, this unit offers an extended capacity for the large volumes of our industrial partners. Molecular distillation is a green technology that uses no solvents or chemicals in the treatment and purification of oils, waxes and fats in general.

Short path distillation is a thermal separation technology operating at process pressures in the range of 1 to 0,001 mbar. It lowers the boiling temperature and is an excellent method for gentle thermal treatment of heat sensitive, high boiling products. The short path evaporator consist basically of a cylindrical body with a heating jacket, a rotor and an internal condenser. The rotor creates a mechanically agitated, thin product film on the heating surface inside of the body. By means of gravity the product flows down in a spiral path, whereby the volatile portion of the product evaporates. The vapour passes by the shortest route and with practically no pressure drop to the internal condenser. The non-volatile portion reaches the lower part of the evaporator and is discharged through the bottom product outlet. The residual vapours and inert gases flow through the vacuum nozzle to the vacuum system.

Comprehensive range of microprocessor operated units for various control modes/functions. The indication and modification of all set points and actual values is done via touchscreen LCD. With optional Ethernet interface for the communication with a PC and CANBUS for the connection to other controller types.
