Extraction systems: Continuous and batch wise.
CONTEX™ counter-current extractor. During continuous extraction the solids are transported by helicoidal screws placed in a tilted trough with heating panels. Hot extraction liquid flows downward through the solids, thereby absorbing the product media.
The IC/FIC™ batch process. The conventional continuous extractor uses a system of batch-operated percolator columns. The solids are fed into the vertical placed percolator tubes and hot extraction liquid flows downward. The extraction takes place under pressure.
The batch IC and FIC™ extractors have been developed by GEA Niro to supply a unique equipment for production of high quality coffee extract for further processing in an instant coffee powder factory. Please visit www.geatube.com/fic to view our animated video on the FIC™ batch extractors.
