In olive oil extraction, malaxation is the action of slowly churning or mixing milled olives, [2] typically for 20 to 40 minutes. The churning allows the smaller droplets of oil released by the milling process to aggregate and be more easily separated. The paste is normally heated to around 27 °C during this process.
Orujo is called the wet solid waste, [2] which is generated by the traditional methods of extraction, based on presses, and the continuous three-phase decanting processes. The process generates additionally one stream of olive oil and two streams of wastes, the Orujo and an aqueous waste called alpechín.
