Abstract
Solids, liquids or gases, particularly those containing cells, bacteria or virus are subjected to supersonic energy in pulses to accelerate physical, chemical or biological alterations, e.g. sterilization, the flow of supersonic energy applied being so powerful that if applied to the substance under treatment continuously, unwanted secondary effects caused by a rise in temperature would occur. Rectangular pulses are preferably employed. Examples relate to (1) the treatment of milk with supersonic osillations of 3000 kilocycles per second in pulses of 5 micro seconds, the pulse repetition frequency being 6000 cycles per second. The oscillating surface has an area of 10 sq. cm. and the milk is passed between this surface and a ground quartz plate 2 cms. away (2) meat is treated at 15 DEG C to destroy enterobacteriaceae for 80 seconds as in (1) above. Specification 356,783 is referred to.ALSO:Foodstuffs are sterilized by the application of supersonic energy in pulses, the flow of supersonic energy being so powerful that if applied to the substance under treatment continuously, unwanted secondary effects caused by a rise in temperature would occur. The pulses of energy are preferably rectangular. Examples relate to (1) the treatment of milk with supersonic oscillation of 3,000 kilocycles per second in pulses of 5 micro-seconds, the pulse repetition frequency being 6,000 cycles per second. The oscillating surface has an area of 10 square cms., and the milk is passed between this surface and a ground quartz plate 2 cms. away. (2) Meat is treated at 15 DEG C. for 80 seconds to destroy enterobacteriace as in (1) above. Specification 356,783, [Group III], is referred to.
