Concentrators, also known as evaporators, are used in the industry for more than 50 years. Aside of multistage, steam heated evaporators Bucher Unipektin is supplying plants with thermal or mechanical vapour recompression as well. SPS-based controls allow the simple and user-friendly supervision

Falling film evaporators with thermal vapour recompression (TVR)

Multiple stage falling film evaporators with thermal vapour recompression are highly energy efficient. By injection of steam the vapours in the thermo-compressor are condensed. Thanks to this, one to two evaporation stages can be compensated in comparison to classical evaporators. The specific steam consumption becomes reduced by up to 50%.


Falling film evaporators with mechanical vapour recompression (MVR)

Evaporators with mechanical vapour recompression are operated with a high-pressure ventilator. Thereby the recompressed steam is used for the heating of the product. A MVR-evaporator can be operated on relatively low evaporation temperatures. Thanks to the low thermal strain, concentrated products of superior quality can be produced. The evaporation costs with MVR-evaporators are considerably lower compared to other designs. For the evaporator evaluation it’s imperative to consider the costs for steam, electricity and cooling water. Our specialists are eager in advising you the most economical solution for your task.
