Patent number: 5200085Abstract: 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.Type: GrantFiled: May 3, 1991Date of Patent: April 6, 1993Assignee: Richter Gedeon Vegyeszeti Gyar Rt.Inventors: Peter Rudolf, Bela Szabo, Ferenc Janko, Erzsebet Neszmelyi, Janos Illes, Istvan Takacs, Ferenc Havas, Gyorgy Bende

Patent number: 4539111Abstract: 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.Type: GrantFiled: March 19, 1980Date of Patent: September 3, 1985Assignee: Richter Gedeon Vegyeszeti Gyar Rt.Inventors: Istvan Takacs, Gyorgy Kerey, Peter Rudolf, Janos Illes, Bela Szabo, Endre Vereczkey, Zoltan Banos, Gyula Bosits, Laszlo Czebe

Patent number: 4518771Abstract: 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%.Type: GrantFiled: December 23, 1980Date of Patent: May 21, 1985Assignee: Richter Gedeon Vegyeszeti Gyar RT.Inventors: Istvan Takacs, Gyorgy Kerey, Janos Illes, Peter Rudolf, Pal Gere, Laszlo Czebe, Erzsebet Neszmelyi

Patent number: 4296072Abstract: Apparatus for the treatment, such as drying, freezing, crystallization of wet solids, slurries, suspensions, pulps and similar materials with heating or cooling.The apparatus is characterized by a treating body having two sections. The first section has a horizontally arranged axially flared annular treating drum rotatable around the horizontal or near-horizontal longitudinal rotation axis, and having end plates with a material feeding inlet pipe leading into the interior through one end plate, while the other end plate is provided with an opening arranged eccentrically in relation to the rotation axis. The second section of the treating body is connected rigidly and thus rotatably to the treating drum, the second section of the treating body having at least three duct-like oblong treating members leading into each other.Type: GrantFiled: March 19, 1980Date of Patent: October 20, 1981Assignee: Richter Gedeon Vegyeszeti GyarInventors: Istvan Takacs, Zoltan Banos, Janos Illes, Endre Vereczkey, Peter Rudolf, Gyorgy Kerey
