Abstract (en)
[origin: WO8102428A1] Method and installation for the continuous acid hydrolysis of a vegetal biological substance for the production of sugar for fermentation of alcohol. The problem relates to the technical and economical execution of the chemical aspect of the known method. There is proposed to use a boiler (11) with horizontal pipes from the cellulose industry, wherein material fragmented by means of an endless screw is continuously supplied. In an appropriate form of implementation, the counter current separation of the hydrolysate is effected in a first stage of a helical separator (13) constantly under pressure with the boiler (11), said separator acting also as a discharge device for the boiler. After the expension (16), a washing of the hydrolysate is carried out in a double filter press (93). At the outlet of the boiler (11) a neutralisation (114) of the acid hydrolysate is already effected.
