Construction

heaters of each effect, separators of each effect, concentrator, thermal compression pump, vacuum system, material delivery pumps of each effect, condensate discharging pump, operation platform, electrical control system, pipelines and valves and etc.

Particular features

1 Best product quality due to gentle evaporation, mostly under vacuum, and extremely short residence times in the falling film evaporator.

2 High energy efficiency due to multiple-effect arrangement or heating by thermal or mechanical vapour recompressor, based upon the lowest theoretical temperature difference.

3 Simple process control and automation due to their small liquid content falling film evaporators react quickly to changes in energy supply, vacuum, feed quantities, concentrations, etc. This is an important prerequisite for a uniform final concentrate.

4 Flexible operation quick start-up and easy switchover from operation to cleaning, uncomplicated changes of product.

Fields of application

1 Capacity ranges of up to 150 t/hr, relatively small floor space requirement.

2 Particularly suited for temperature-sensitive products.
