Abstract

1,222,208. Sterilizing with microwaves. HIRST (MICROWAVE HEATING) Ltd. and RICHARD ENGS. Ltd. 6 Nov., 1968 [6 Oct., 1967], No. 45943/67. Heading A2D. [Also in Division H5] Flowable materials, such as liquids, food pastes, pÔtÚs or small food items, are sterilized by microwaves while maintaining the materials under pressure. The material is fed from a reservoir 11 to a pump 13 which forces it into a tough glass tube 14 and through a pressure valve 16 that maintains the material in the tube 14 at a superatmospheric pressure. The tube 14 passes through a conductive-walled cavity 18, Fig. 1, fed with microwave radiation by a waveguide 19, or as shown in Fig. 2, the tube 14 passes through a waveguide 18<SP>1</SP> having a magnetron 21 at one end 19<SP>1</SP> thereof and a dummy load 23 at the other end 22 thereof. In both embodiments, means 17 for indicating and/or recording temperature and pressure, and cooling means 20 to reduce the temperature of the sterilized material below 100‹C., are also provided. The sterile material emerging from the valve 16 through a tube 15 is packed and sealed in sterile containers under sterile conditions in a packing station irradiated with ultraviolet radiation.
