要約(英語): The sterilization methods of several drinks are mainly based on thermal sterilization process, as it is cheaper and easier to be performed. But thermal process may change the original taste of the drinks due to chemical change in it. But on the other hand, the non-thermal sterilization methods like Ultra Violet (UV) radiation, pulse light, filtration etc. are yet not to spread out due to the economical and technical problems. We have developed a non-thermal sterilization process controlling the motion of ferrite particles in the liquids. Ferrite particles are non toxic and they are ferro magnetic particles which motion can be easily controlled by magnetic flux. Ferrite particles were put in a plastic container with liquid. Two electromagnets were set up in vertical direction with a certain gap in between them. The container was hold in between the two electric magnets. These electromagnets were controlled by an AC supply. By controlling the movements of ferrite particles with liquids with different microorganisms, sterilization of the liquids had been achieved. This paper also describes the process of sterilization by ferrite particles. We also applied our process on Escherichia coli with different types of ferrite particles and achieved sterilization.
