Film production - Import export

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.

Application in film production and equipment as well as in the production of hygiene goods

A rainbow film ensures that the packaging design of computer game and action figures stands out on the shelf. For an ideal print image, the rainbow film is first offset printed with opaque white and then in four colour and that too in 16 different language versions. The clear view of the characters boosts the "buy me!" effect of the product packaging.
