Alfa Laval X-series decanters have been designed for 3-step processing. The way in which the decanter was designed brings a number of benefits to the processing of the oil, including higher quality as well as a higher yield than the norm. SIGMA decanters with ALFA LAVAL technology can be defined as “smart decanters” also thanks to the ease of access to the drum (stainless steel lid that opens quickly and easily), representing the ideal choice for customers looking for high performance, reliability and high quality. The entire range of the Sigma series is equipped with a double inverter system called “Basic”, which allows the adjustment and adaptation of the differential revolutions of the screw during processing; this mechanism allows considerable energy savings and guarantees high performance of the decanter on any type of processing. The decanters of the X series with higher capacity are also used for the revision of the pomace.
