    摘要: According to the process the sludge is homogenized and heated to 30.degree.-60.degree. C. temperature. The heated sludge is circulated under 2-4 bar overpressure, and its temperature is raised to about 130.degree.-150.degree. C. in 1-2 sec by conducting steam of 130.degree.-151.degree. C. and 2-4 bar pressure directly into the sludge, thus granulation is brought about in the sludge. The sludge of increased temperature--while its temperature and pressure maintained--is further circulated for about 60-300 sec. Then, the sludge is adiabatically expanded in 1-2 sec by reducing the pressure to about 0.01-0.02 bar. The expanded sludge is separated to water, fat containing water and solid impurity and wet solid phase containing protein.It is characteristic to the apparatus that it is provided with device for heating the sludge, and pipe (18) for passing on the heated sludge connected with the heating unit (5) where an expansion valve is built in. Pipe (22) joining the separating tank (7) is connected with the expansion valve (6). The apparatus is provided with separator for separation of the sludge leaving the tank (7) to water, fat and solid phase.

    摘要: Process for the extraction of solids from liquids containing solids granulated by heat effect and/or solids the moisture content of which is reducible by heat effect, especially from colloidal solutions with protein content, suspensions and slurries for reducing the fat content of the solid material, in the course of this process grains are formed in the liquid with heat effect, or the moisture content of the grains is reduced, then they are removed from the liquids and dried. The equipment for implementation of the process is also subject of the invention. The process is characterized by heating the liquid to 50.degree.-125.degree. C. temperature with heat transfer ("instant heating ") for a short period, maximum for 2 minutes, then the heated material is kept at 50.degree.-125.degree. C. temperature for at least 2, preferably for 5-15 minutes. This is followed by separation of the grains from the liquid phase with filtration in a space containing vapor of 50.degree.-125.degree. C. temperature, the filtration process carried out in minimum 4, preferably in 8-15 minutes. Should the solid material contain fat, then at least a certain part of the fat is melted with the heat treatment processes. Finally the wet solid material separated from the liquid is dried. The equipment is provided with collection tank, instant heater, preferably with gravitational filter arranged in closed space, as well as with a drier. These are united in a closed system with pipelines and feeder device(s), with one or several pumps.
