Abstract

The present invention relates to a process for extracting starch, fibres and protein from a plant-based raw material. The process comprises supplying slurry of plant-based flour and water to a hydrocyclone system (720), which provides a first flow (F1) comprising the fibres (F) and protein (P) extracted from the plant-based raw material and a second flow (F2) comprising starch (S) extracted from the plant-based raw material. The first flow (F1) is supplied to a first centrifugal separator (S1) to provide a fibre fraction as a third flow (F3) and an aqueous protein-containing fraction as a fourth flow (F4), to which acid is added to precipitate dissolved proteins. The flow (F4) is separated into a liquid light phase comprising whey (Wh) and a heavy phase comprising concentrated protein-containing fraction (CP), by using a highspeed centrifugal disc stack separator (2; S2, 72) comprising a heavy phase outlet and/or light phase outlet that are/is arranged in fluid connection with a flow influencing means (6; 12); and wherein the separating in the second centrifugal separator (S2) comprises regulating the flows at the heavy phase and/or light phase outlets by means of the flow influencing means such that the content of the protein-containing fraction at the light phase outlet is minimized.
