The array induced electric field fluid reaction system comprises a reaction unit array with a plurality of reaction units interactively connected as a network configuration, a power supply and a sample container, wherein each reaction unit has a closed iron core, a primary coil and a secondary coil. The primary coil and secondary coil are, respectively, wound around two sides of the closed iron core, and the secondary coil comprises an insulation pipe for circulating the reaction medium. When the array induced electric field fluid reaction system operates, no charged needle-type electrodes or electrode plates are inserted into the reaction medium. Electrochemical reaction and metal contamination may be avoided. The reaction units can form an array network connection and series/parallel connection, and when the induced electric field in each reaction unit is acted on the reaction medium, specific reaction effects may be achieved.

The present invention refers to a compact device for electrolytic sterilization of food and utensils, especially for the electrical treatment of food and utensils using the electric current generated between a positive pole and a negative pole of an electrolysis system, all of those immersed in a fluid medium contained within a container covered by a lid of said device. The container is the anode or positive pole and the lid, by means of a cathode shaft provided with a cathode disc, is the cathode or negative pole, and the electrolyte is water.

An object of the present invention is to provide a preservation treatment apparatus which can sufficiently apply an effect generated by charges to an object to be preserved thus more surely exhibiting a preservation effect generated by charges, and can stably hold an effect of a potential applied to the object to be preserved by controlling the flow of an electric current in a stacked portion of the object. A preservation treatment apparatus includes: a conductive enclosure structure arranged at least either one of both sides or an upper side of the placing portion 1, and surrounding at least either one of both sides or the upper side of the object O as viewed from the object O placed on the placing surface; a first electrode 21 brought into contact with an upper position of the placing portion 1 close to one side portion 11S of the placing portion 1; a second electrode 22 brought into contact with a lower position of the placing portion 1 close to the other side portion 12S of the placing portion 1; a third electrode 23 brought into contact with a position of the enclosure structure close to one side portion of the enclosure structure; a fourth electrode 24 brought into contact with a position of the enclosure structure close to the other side portion of the enclosure structure; and a voltage supply portion 20 which is electrically connected with these electrodes respectively. The voltage supply portion 20 simultaneously applies a negative DC voltage to either one of the first electrode 21 and the second electrode 22 and applies an AC voltage to the other one of the first electrode 21 and the second electrode 22.
