Abstract: 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.

Abstract: A heparin-enriched material capable of long-term storage and particularly adapted for use as a raw material in processes for the extraction of heparin is produced by storing the animal organ material for a period of 0.5 to 15 hours (preferably 4 to 6 hours) at a temperature of 10.degree. to 50.degree. C. (preferably 30.degree. to 50.degree. C.), then injecting steam to effect a heat treatment at a temperature between 75.degree. and 100.degree. C. The heat treatment precipitates heparin-containing aggregate which is filtered from the aqueous phase and dried to a dry substance content of 90 to 95%.

Abstract: A process for producing an aqueous solution of high heparin content from heparin-containing animal organs comprises forming a heparin-enriched granular raw material from these organs and extracting the raw material at a temperature of 20.degree. to 80.degree. C. with a salt solution having a salt concentration of 1.5 to 12.0% and a pH in the range of 8 to 12.8 or an alkalinity of 0.5 normal to 1.08 normal concentration. The dry substance to liquid ratio should be 1:5.
