A method for producing crude palm oil from a palm- oil containing raw material and a system for the production of crude palm oil

Abstract

The present invention relates to a method and system for producing crude palm oil from a palm-oil containing raw material comprising receiving and feeding the palm-oil containing raw material to a sterilizer (11), sterilizing the raw material in the sterilizer (11) by means of steam, threshing the raw material in a thresher unit (12), digesting fruits in a digester unit (13), and pressing the fruits in a pressing arrangement (14) to extract palm oil from the digested fruits, clarifying the extracted palm oil in a clarification tank (15) and drying the extracted palm oil in a dryer unit {18) to produce crude palm oil, whereby during the production a palm oil mill effluent (POME) is generated as a residual sludge, and the method further comprises: (a) Separating water (A) and solids (B) from at least part of the palm oil mill effluent (POME) by using a POME separator (26); (b) Feeding at least part of the separated water (A) to a steam generator (21), which is a separate and different device compared to the mill boiler; (c) Generating steam (C) in the steam generator (21) by using the separated water (A); (d) Feeding the generated steam (C) to the sterilizer (11).
