The invention relates to a 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 incorporated in the system. Advantage of the invention is that the extraction of the solid content of solutions, slurries etc., which are difficult to treat and reduction of the possible fat content of the solid material are realized with a simple means in such a way, that an excellent end-product is available in respect of both the qualitative and other utilization properties.
