The patented CASCO process for distillate treatment promises a further increase in the quality of high-quality distillates and the elimination of minor sensory defects. It enables the reduction of elevated methanol and cyanide contents.
The system consists of a vessel with built in agitator and a specially shaped lid. The alcohol to be refined is filled into this tank. By heating the distillate in the vessel, volatile substances escape from the distillate. By cooling the lid at the same time, these vapours condense at its surface and are discharged that way.
While veiled fruit aromas develop a better sensory in high-quality distillates, aroma-relevant ingredient are not reduced. With faulty distillates, ingredients that are problematic to health such as methanol and cyanide contents are reduced. After the refinement treatment, the container can be cooled as well and serves as preparation for cold filtration.
