The IC and FIC™ batch extractors
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.
This extractor consists of a number of vertical percolator columns
arranged in a battery. Each column – or vessel – is in turn filled
with ground coffee beans, after which water at a predefined
temperature is added. This process is in principle a batch process.
By means of a valve manifold, the columns are inter-connected,
and thereby the extraction process becomes continuous and
counter-current, which gives an excellent quality of coffee extract,
where it is possible to control the yield and quality of the aroma fraction.

The IC extractor has a well known design with the columns (percolators) placed in a straight line for easier
overview and manual operation by the plant operator. It is possible to divert/split the extract from each
column in an aroma fraction (the first) and a hy-drolysis fraction (the last) before it is passed on to the next
column.
The extraction time is short and it is possible to discharge the wanted amount of the aroma fraction for further
treatment in an aroma recovery equipment. The utilization (high yield) of the coffee beans can be controlled,
as the extractor is pressurized.
FIC™ (Fast Extraction Mode)
Dry ground coffee beans are pre-wetted and then filled into the column(s). This freshly charged column is
then evacuated for air followed by a soaking with hot fresh water, allowing the high quality first draw to be
extracted with only pure fresh water at the desired temperature.
Two separate extraction water streams at different stages are used to obtain a controlled high quality aroma
fraction, which can be discharged separately from the hydrolysis fraction. In the “FIC™” mode the operation
of the extractor battery is fully automatic. This secures a minimum (short) extraction time and full control of
the amount and quality of the aroma fraction, as well as solids content (yield) of the hydrolisis fraction. The
extraction is, as in the “IC” mode done under pressure.
