Industrial Extractors

Some general trends concerning efforts for improving extraction efficiency and performance can be observed. Development of an extractor implies a compromise between simplicity with respect to the number of moving parts and transporting systems, such as solvent pumps and solid-conveying systems, and efficiency of recirculation pattern for the miscella. Extractors containing compartments, as op- posed to simple conveyer belts, facilitate submersion of the solid, which usually leads to higher extraction efficiencies.
