During operation, the scrapers continuously keep the heating jacket of the vessel free of buildup and encrustations. This is necessary because the extract, which is as viscous as honey, is concentrated very gently under vacuum. When the process is finished, the liquid solution has a significantly higher active ingredient content. At the same time, the continuous mixing by the agitator ensures a good heat exchange in the vessel contents.
Due to its strong focusing and unrivalled ability to "measure past" interfering vessel installations, VEGAPULS 64 is a perfect match for the pharmaceutical industry. With a 2'' clamp fitting, and its beam angle at only 6° – it is perfect for avoiding the scraper, the container wall and able to track the liquid level unimpeded all the way down to the vessel bottom. .
The advantages: Complete emptying of the vessel is guaranteed at the end of every batch. Any false echoes, like those generated at close range by the rotating crossbeam of the mixer, are intelligently suppressed by the sensor, thanks to its especially high dynamic range. This enables exact monitoring of the solution’s concentration throughout the evaporation process.
