Abstract

691,411. Rapid sterilization. BRAUNSCHWEIGER GES. FUR ANGEWANDTE ELEKTRIZITAT. Jan. 26, 1950 [Jan. 27, 1949], No. 2252/49. Class 49. Substances are heated for sterilization or pasteurization through a temperature range of at least' 30‹ C. to a temperature of at least 65‹ C. with a heating velocity of 70-100‹ C. per second. The initial temperature may be room temperature; the higher temperature is preferably 65-95‹ C.; the substances are preferably kept at the higher temperature for a maximum period of 10 sec. Cooling may follow the heating. The process is especially applicable to liquids, pulps and pastelike substances in a continuous manner. Vaccines and sausage meat are referred to specifically. Heating may be by heat conduction or radiation, electrically by passage through electrode lines connected to an alternating voltage of normal frequency, or, particularly for pulps and pastes of poor heat conductivity, by high or ultra-high frequency alternating electric field. The graph indicates the extent of destruction of E. Coli in a nutrient medium heated from room temperature to 65‹ C. and maintained at this temperature for 10 sec., for various heating velocities, the abscissµ being the heating velocities in deg. C. /sec. in logarithmic scale and the ordinates being the proportion of the numbers of living bacteria to bacteria originally present, also in logarithmic scale.
