    摘要： 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.

    摘要： A device (1, 2), a method for electrolysis and a use of the device to perform electrolysis are provided. The device (1,2) comprises heat transfer plates (5) defining alternately arranged first and second interspaces (I1, I2) and, within these, first and second flow channels (C1, C2). A first fluid path (P1) for conveying a first fluid through the device (1, 2) extends through the first flow channels (C1). The device is characterized in that membanes (45) are arranged in the second flow channels (C2) to divide them into second primary sub channels (C2P) and a second secondary sub channels (C2S). Further, a second fluid path (P2) for conveying the second fluid through the device (1, 2) comprises a second primary fluid path (P2p) and a second secondary fluid path (P2s). The second primary fluid path (P2p) extends into and out of the second primary sub channels (C2P) via the first interspaces (I1) outside the first flow channels (C1). The second secondary fluid path (P2s) extends into and out of the second secondary sub channels (C2S) via the first interspaces (I1) outside the first flow channels (C1).

    摘要： The present invention provides a centrifugal separator (1) for separating at least one liquid phase from a liquid feed mixture-. The centrifugal separator (1) is comprising a frame (2), a drive member (3) and a rotating part (4), wherein the drive member (3) is configured to rotate the rotating part (4) in relation to the frame (2) around an axis of rotation (X), and wherein the rotating part (4) comprises a centrifuge bowl (5) enclosing a separation space (9). The centrifuge bowl (5) further comprises an inlet (14) for receiving the liquid feed mixture and at least one liquid outlet (6,7) for a separated liquid phase; wherein the separation space (9) comprises surface enlarging inserts (10) for increasing the separation performance. The centrifuge bowl (5) comprises a bowl wall (30), in which a first (31) and a second (32) channel extend, wherein the first (31) and second (32) channels extend in different directions (D1, D2) but intersect at an intersection point (Y) in which there is a fluid contact between said first (31) and second (32) channels. The first channel (31) is arranged such that during rotation of the centrifuge bowl (5), stress concentration regions (40) in the bowl wall (30) are generated on two opposing sides (31a, 31b) of the first channel (31) and lower stress regions (41) are generated in the bowl wall (30) on the other two opposing sides (31c, 31d) of the first channel (31), as seen in the cross-section in the plane (A) perpendicular to the direction (D1) of the first channel (31). The second channel (32) is arranged so that it intersects the first channel (31) with its center line (Z2) shifted towards a lower stress region (31c,d), as seen in the cross-section in the plane (A) perpendicular to the direction (D1) of the first channel (31).
