In an enzymatic saccharification process, a sugar solution of constant sugar content is obtained by adding to the starch-containing raw materials, prior to the enzymatic saccharification step, part of the sugar solution obtained after the saccharification step and being separated from solid material and having been brought to a higher concentration, so that a higher sugar content, in particular within the range from 15 to 22% by weight and preferably approximately 20% by weight, can constantly be maintained, independent of the concentration and quality of the raw materials.

The apparatus for continuously separating liquid phases of different density consists of a separating basin (1) within which are arranged partition walls (5) for being lifted and lowered and for being moved one in direction to the other or for being swivelled. Swivelling of the partition walls (5) is effected about an eccentrically arranged axis (7) such that during the swivelling movement the partition walls (5) are simultaneously lifted or lowered. The partition walls (5) can be driven by push rods (8) and thus be swivelled in the contrary sense. When swivelling the partition walls (5) in one direction, the liquid level is lifted in the chamber defined between the partition walls and is lowered in the adjacent chamber, noting that the portion having the lower specific gravity flows over the upper edge, assuming a lower level, of the one partition wall in one direction (11) and that the proportion having the higher specific gravity flows in direction of the arrow (12), i.e. in the opposite direction, below the bottom edge of the outer partition wall (5). The separated phases are collected at the front sides of the separating basin (1). Supply is effected by a supply means (10) approximately centrally of the separating basin (1).

The solid jacket centrifuge is a plural chamber centrifuge (1). A housing (2) is, together with the centrifuge, stationarily supported, noting that a carrier (6) for cylindrical mantle surfaces (7 and 8) is provided within the housing (2). The cylindrical mantle surfaces (7 and 8) delimit annular chambers (9 and 10) and are shiftable in the direction of the axis of the shaft (3). There is further provided a screw conveyor (12) for introducing the material to be dewatered. The material to be dewatered enters the first annular chamber (9) via radial channels (15). By shifting the cylindrical mantle surface (7) in the axial direction, the material is discharged in a radial direction into the concentric greater annular chamber (10). When subsequently the mantle surface (8) is moved in the axial direction, discharge is again effected in the radial direction.

It is proposed to demulsify and convert emulsions of oils, greases, and fats in that these emulsions are processed together with digested sludge or sludge liquor from a biological sewage treatment plant. The emulsions of oils, greases, or fats are fed after a first digesting step and preferably to a separate container. In that second digesting step, the bacteria growing under anaerobic conditions can convert much larger quantities of emulsions and the emulsions can be converted within a shorter time.
