Deoiling single-strength orange juice extracted from FMC extractors utilizing a centrifugal separator has traditionally been a difficult task. New technology utilizing hermetic separators has proven very successful for this application. Processors are able to use maximum yield recovery settings in the extractors and hold the separator accountable for reducing the oil content and defects in the juice to acceptable levels.
With the demand for Not-From-Concentrate premium orange juice rapidly increasing in the United States, the processor must be able to recover as much juice from the fruit as they can. During certain periods of the production season, the oil in the juice exceeds the USDA grade standards of 0.035%. In order to maintain this high quality juice throughout the processing season, the demand for new technology in oil reduction was required. New technology, utilizing hermetic separators for deoiling, has lead to significant gains in juice yields.
