EVALUATION OF FUNCTIONAL CAPABILITIES OF DIFFERENT TYPES OF CENTRIFUGAL OIL EXTRACTION SYSTEMS

In order to evaluate the functional capabilities of the following continous-operation olive oil plants of centrifugal type (PIERALISI, CHEROUVIM, WESTFALIA and DEUTZ) an experiment was conducted at the Subtropical Plants and Olive Trees Institute of Chania during the olive harvesting period. ‘Koroneiki’ olive fruit at different maturity stages was used for running 20 replications for each centrifugal system. The following results were obtained for all the extraction systems. The industrial yield exceed the 85%. The oil content of olive residue (at 25% moisture) was less than 9%. The loss of oil in the vegetable water was less than 0.8%. Moisture plus foreign substances were less than 0.7%.
