Evaporators and Heat Exchangers

In the evaporation unit the dry substance (DS) of the product is increased up to the typical market demands without changing the color, taste and odor.

It has been equipped with the latest technology automation equipment and sophisticated scada systems, from which the volume of the product feeding into the system, energy input, the volume of output product, body heat, and system pressure and other critical process parameters are observed through the operators’ screen and are automatically controlled.

The use of the control system through the latest automation systems technology helps us to have maximum evaporation by using minimum energy.

All historical measures and control data can be accessed through the use of automation systems. As a result, the quality of product would be stable and standardized, independent from the human factor.

We are fabricating floating head, fixed tubesheet, U-tube and other shell & tube type heat exchangers. (horizontal or vertical, overhead condensers, evaporators, suction heaters, condensers for vacuum systems and similar.)
Exchangers are designed and fabricated according to ASME Sec. VIII Div.1, AD 2000-Merkblatt or to other codes specified by the customer.

We manufacture ergonomically studied, easy to assemble, prefabricated units, with easy to use walking paths, platforms and stairs. In addition to stainless steel exchangers, if required, we can supply exchangers with various construction materials that include all kinds of duplex steels etc.

If required, we can supply thermal design as well for shell and tube type heat exchangers.

Falling Film Evaporator

Vertical shell-and-tube heat exchanger, with laterally or concentrically arranged centrifugal separator.

Working principle
The liquid to be concentrated is supplied to the top of the heating tubes and distributed in such a way as to flow down the inside of the tube walls as a thin film. The liquid film starts to boil due to the external heating of the tubes and is partially evaporated as a result. The downward flow, caused initially by gravity, is enhanced by the parallel, downward flow of the vapour formed.Residual film liquid and vapour is separated in the lower part of the calandria and in the downstream centrifugal droplet separator.

• Best product quality – due to gentle evaporation, mostly under vacuum, and extremely short residence times in the evaporator.
• High energy efficiency – due to multiple-effect arrangement or heating by thermal or mechanical vapour recompressor,
based upon the lowest theoretical temperature difference.
• 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.
• Flexible operation – quick start-up and easy switchover from operation to cleaning, uncomplicated changes of product.
