| 摘要 |
<p>The invention relates to a method of recovering the maximum amount of liquid from the sediment of the plant material in the production of bioetha- nol, and this is achieved according to the invention by feeding the sediment (9) to a separating press (1 ), in which the sediment is subjected to a variable, pulsating compression pressure, whereby the liquid (13) is expelled in an effective manner. The liquid (13) may then be returned to the initial phases in the ethanol producing process, thereby ensuring an optimum yield. The separating press (1 ) comprises a screen shell (2a-2c) with a worm (4, 5), which parts are rotated in opposite directions, and with a valve (15, 16, 17) which controls the compression pressure.</p> |
