Abstract

An electric field treatment device for electric field treatment with an efficiency higher than that of conventional electric filed treatment. The electric field treatment device is characterized by performing an electric treatment by the following procedures. By applying a same-polarity alternating voltage to an opposed electrode, an object to be treated in an electric filed is electrodized to have the same polarity as that of the electrode. When the object is elecrodized to be at a positive potential, the positive polarity sides of the polarized constituent molecules in the object are aligned and oriented toward the infinite far space. Contrarily, when the object is elecrodized to be at a negative potential because of the inversion of the polarity of the applied alternating voltage, the negative polarity sides of the polarized constituent molecules are aligned and oriented to the infinite far space. Thus, the electrodized constituent molecules are alternately aligned and oriented by the polarity inversion of the applied alternating voltage.

Electric field treatment equipment and applied equipment for applying alternating voltage of the same polarity

 The present invention relates to an electric field processing apparatus for processing an object to be processed by an electric field by applying an alternating voltage having the same polarity to a plurality of electrode bodies to generate an electric field, and an application apparatus using the electric field processing apparatus. Here, the application of an alternating voltage of the same polarity refers to the application of an alternating voltage of the same polarity (that is, plus or minus) and the same potential to a plurality of electrode bodies, and a different polarity for an infinite space. Having alternating voltage applied. This is a new concept of alternating voltage application that can be compared with the application of a different polarity alternating voltage according to the prior art in which a positive potential is applied to one electrode and a negative potential is applied to the other electrode. The application of the alternating voltage of the same polarity according to the present invention is more efficient than the application of the alternating voltage of the opposite polarity according to the prior art. Used when processing. The electric field treatment referred to here is to electrically polarize the constituent molecules inside the object to be processed along the direction of the electric force in the electric field reached by the application of the alternating voltage, and to repeatedly conduct the polarized constituent molecules. While alternating and aligning in the direction of the force line, the arrangement of the constituent molecules is gradually and regularly aligned to remove impurities mixed in between the constituent molecules, or to actively supply ions to the constituent molecules, and at the same time, It means that by applying an induction current to the constituent molecules, various effects are given to the object to be treated and reformed. An electric field is a physical region in which an electric field is formed. Background art

Conventionally, there is an apparatus provided with a high voltage processing function or an electric field processing function for reforming a fluid (water, oil, gas such as air containing a certain amount of water vapor). Generally the water is not necessarily being the composition with only a single molecule of hydrogen element and oxygen element is bonded, actually a population of molecules formed by the interaction between molecules of the monomolecular each other hydrogen bonding of water as H ₂ 0 (Hereafter, this is a class Ter). Tap water, which dissolves many impurities and gases during the class, has large clusters and many irregular clusters compared to electronic water. Therefore, in order to generate “good water”, which is generally called, it is necessary to use some method to reduce the size of the cluster of water and generate water composed of uniform clusters. Electric field treatment is also applied to purify wastewater containing biodegradable substances such as macromolecules, aromatic compounds, and COD components. Ozone and reactive oxygen species (OH) are directly dissolved in water from dissolved air (oxygen). Radicals), and these ozone and OH radicals act directly on hard-to-biodegrade substances in water to inactivate these substances, thereby purifying water, sterilizing and sterilizing the surface of the substances. It is possible. FIGS. 13 (A) and 13 (B) show an underwater discharge device 250 disclosed in Japanese Patent Application Laid-Open No. 2001-0463 (Kobe Steel). This underwater discharge device 250 applies ozone and OH radicals by applying an alternating voltage of different polarity between the high-voltage electrode plates and discharging it in the water to be treated, thereby producing a biodegradable substance in the water. Harmless or inactive. The figure (A) shows the charge distribution in the preceding polarity (positive here) phase (indicated by the arrow in the figure) in the pulse power supply 254. The water molecules in the container 251 are polarized by the electrode charge, and the polarization charge of the opposite sign is induced on the electrodes 253, 253 on the inner surface across the container wall. At this time, the electric field is canceled by the polarization in water, and the electric field gradient is concentrated between the electrodes 25 3 and 25 3 across the container wall. FIG. 13 (B) shows the charge distribution and electric field in the phase of the reverse polarity (indicated by the arrow in the figure) following the pulse waveform of FIG. 13 (A). In this case, the distribution of the electrodes is offset by the reversal of the pulse polarity, but the polarization of the water in the vessel 25 1 is maintained for a short time because the polarization reaction of the water molecules is slow, and the electrodes are maintained. The surface charges facing 25 3 and 25 3 remain. As a result, a large electric field is instantaneously generated in the vessel 251, causing discharge, and the remaining oxygen in the water is excited to generate ozone, and Water is excited by ultraviolet rays generated by the excitation, and ΔH radicals are generated. As a result of their sequential dissolution in water, the ozone and OH radical concentrations in this water will increase. In other words, the present underwater discharge device has a structure in which ozone and 〇H radicals generated by these discharges inactivate hardly biodegradable substances contained in wastewater and the like. However, in this underwater discharge device, electric field treatment cannot always be performed uniformly because different potentials are applied to the left and right electrodes 25 3 and 25 3. Next, FIG. 14 is a conceptual diagram of a conventional thawing cabinet 244 to which the above-described electric field treatment disclosed in Japanese Patent Application Laid-Open No. 2-2577867 (Otsuki) is applied. This device electrically insulates the inside and outside of the freezer, and uses a high-voltage transformer 241, for example, as a negative electron generator by electrostatic induction, and insulates one pole on the secondary high voltage side. The other one pole is connected to a shelf plate made of a conductive metal material such as a stainless steel plate, and a negative electrode is applied by electrostatic induction, and the object to be processed (thawed product) is placed on the shelf plate. Thawing is carried out by directly contacting 4 3. Reference numeral 242 denotes a refrigerator. In the structure where the object to be processed is thawed by bringing the object into direct contact with the conductive shelf, the contact resistance between the conductive shelf and the object is generated, and this contact resistance generates Joule heat. As a result, the molecules of the object to be treated cannot be perfectly aligned and aligned at the molecular level, so that the thawing finish of the object to be treated lacks homogeneity. In addition, a large amount of electric field processing and thawing cannot be performed uniformly by directly placing an object to be treated with an insulating material and an untreated object on the same current-carrying shelf. Next, FIG. 15 is a conceptual diagram of a refrigerator 201 provided with an electric field processing apparatus according to the prior art disclosed in Japanese Patent Application Laid-Open No. 9-138055 (Matsushita Refrigerator). In this refrigerator 201, part or all of the low-temperature room is made into an electric field processing room 203.In this electric field processing room 203, one pole on the output side of the transformer 205 is provided. A high-voltage electrode 209 connected to the second electrode 207 and a flat plate counter electrode 211 connected to the other electrode 207 B on the output side and facing the high-voltage electrode 209. Have been. That is, alternating voltages of different polarities are applied to the electrode plates 209 and 211. Then, the object 2 1 2 to be refrigerated is placed on the flat plate counter electrode 2 1 1, and a high voltage weak current 2 13 is applied to both the high voltage electrode 2 09 and the flat plate counter electrode 2 1 1. Thus, a high-voltage weak alternating current 2 13 is applied to the object 2 12. The purpose of this electric field treatment is to apply a high voltage between the electrodes in the refrigerator in the temperature range from the time of storing the food until the inside of the electric field processing chamber 203 is cooled to 0 ° C or less, so that the Since the water molecules are electrically polarized and temporarily oriented and aligned in the direction of the lines of electric force, and the water is hardly frozen by the reforming of the water, the food temperature is temporarily reduced. To create a supercooled state that does not freeze even when the temperature reaches C. As a result, it does not freeze at temperatures from 0 ° C to 15 ° C, where cell destruction of food occurs due to cooling. Therefore, the destruction of the cells of the food is suppressed, the freshness is maintained by the low-temperature storage, and the food is not frozen and stored without losing the taste of the food, and the quality of the food can be improved. However, the structure in which such different polar potentials are applied to the electrode plates is limited to generating a supercooled state that does not freeze even if the food temperature temporarily reaches 15 ° C. In fact, it is difficult to create a supercooled state. When the electric field processing chamber 203 to be applied is used, a container for accommodating the object to be processed 212 or an electrical effect on the object to be processed by a material of the packaging material, for example, a conductive material, an insulating material, or the like. However, there was a problem in that there was variation. In addition, when the container to be processed has a lid, when the container to be processed is entirely made of an insulating material, or when the container to isolate the container to be processed is stacked, etc. On the other hand, there is a problem that the high voltage weak current 2 13 of the high voltage electrode 2 09 is shielded from 2 12, and the electrical effect on the object 2 12 is hindered. Also, when using the electric field treatment room 203, carelessly 0 If water is spilled in 3 and this spilled water is left, the electric field lines in the electric field concentrate on the spilled water, and the electric field effect on the food to be processed by the electric field treatment decreases. There was a problem that such difficulties occurred. Furthermore, in this configuration, since the flat plate counter electrode 2 11 1 side of the electric field processing chamber 203 is connected to the ground 2 17, the electric power is low, so that the electric field processing chamber 203 is placed in the electric field processing chamber 203. When the object to be processed is stored in a conductive metal container, or when the object to be processed is stored in an insulating container and the outside of the insulating container is wet, the electric flux lines are formed of conductive metal. There is a problem that the electric field effect on the object to be treated is reduced due to the water splashing on the container or the water outside the container, or it does not function at all. Also, alternating voltages of different polarities are applied between the two electrodes, and the electric field strength is inversely proportional to the distance between the high-voltage electrode 209 and the flat plate counter electrode 211. The electric field strength drops significantly. Therefore, if the arrangement distance between the two electrodes cannot be increased, the electric field processing chamber 203 will have a smaller storage capacity for the workpiece, and the outer shape of the workpiece will be limited. There is a problem that a difficulty occurs on the storage surface of the processing object. Next, FIG. 16 shows a conditioning flyer equipped with the electric field processing apparatus according to the prior art disclosed in Patent 34377165 (KSA) to which the above-described electric field processing is applied. It is a conceptual diagram of 220. Flyer one _{2 2} 0 gave this kind of electric field treatment apparatus, the interior of the oil tank 2 2 7 having an opening 2 2 3 are insulated construction with insulating material 2 2 4, insulation in this oil bath 2 2 within 7 A shielded current-carrying electrode 226 and a ground electrode 228 opposing substantially parallel to the current-carrying electrode 226 are arranged. The ground electrode 228 is connected to the ground wire 229. Then, one pole 207 A on the output side of the transformer 205 is connected to the conducting electrode 226, and the other pole 207 B on the output side is grounded via a resistor R. . In other words, alternating voltages of different polarities are applied to the electrode plates 209 and 211 as in the above-described refrigerator. Inside the oil tank 2 27, there is stored a fry oil 2 25, and a plurality of The heating pipes 221 are arranged parallel to each other so as to extend in the horizontal direction along the bottom surface of the oil tank 227. For example, a frying food material 222 as an object to be treated is put in a fry oil 225, placed on the above-mentioned current-carrying electrode 226, and fried. At this time, the configuration is such that the leakage current from the current-carrying electrode 226 is controlled so that a high-voltage weak current is applied to the object disposed between the two electrodes 226, 228. ing. In these fryers equipped with a conventional electric field treatment device, shortening of the frying time is the greatest requirement from the food production and processing site. In fact, the flyer 220 is a high heating process that controls the leakage current from the current-carrying electrode 226 during frying, so that in terms of heat concentration and heat transfer to the buried object, Although the flyer 220 is superior to the conventional flyer which has no processing function at all, it is difficult to shorten the production time only by adjusting the output on the secondary side in order to improve productivity. There was a problem. For example, if the output on the secondary side is increased for the purpose of shortening the production time with higher efficiency, the production time cannot be reduced unless the environmental oil temperature is raised at the same time. A problem arises in that the coloring of the skin portion becomes worse. In addition, shortening the above-mentioned frying time and increasing the degree of oil infiltration into the material to be treated are also requirements from the food production and processing site. For foods that require oil impregnation, in the above-mentioned flyer 122, the skin formation time of the object to be treated is fast, so the skin formation time and oil impregnation are controlled by adjusting the output on the secondary side. There was a problem that it was difficult to adjust the condition. For example, if the output on the secondary side is reduced for the purpose of oil penetration, the effect of oil penetration can be achieved, but conversely, the production time cannot be shortened. Furthermore, in the former fryer 220, when frying is performed on an object having a large volume and weight or an object having a large amount of moisture contained in the skin, There is a problem that the progress of the skin formation is different between the skin portion on the upper surface of the processed material and the skin portion on the lower surface in contact with the current-carrying electrode 226. For example, an object to be processed having a large volume and weight or an object having a large amount of water contained in the skin comes into close contact with the current-carrying electrode 226, so that a high-voltage weak current surrounds the object to be processed and affects heating. The effect was disturbed. In addition, since the flyer 220 equipped with the conventional electric field treatment device controls the leakage current, "variation" occurs in the time reduction depending on the amount of the workpiece to be charged into the oil tank 227. There was a problem of doing. For example, when the amount of the material to be treated is small, a long frying time is required, and when the amount of the material to be treated is large, the frying time is reduced. This means that if small-volume production suddenly becomes necessary, it will be difficult to reduce the production time, and the workpiece will not be able to cope with short-time production in small quantities. Further, in the flyer 220 provided with the above-mentioned conventional electric field processing apparatus, since the leakage current between the current-carrying electrode 222 and the earth electrode 228 opposite to the current-carrying electrode 226 is controlled, the flyer Various products such as hydrolyzate and heat denatured product generated in the process are attached on the side of the current-carrying electrode 226 so that they serve as contacts, and extended and fixed to the ground electrode 228 There was a problem that would be done. This state means that it is impossible to control the amount of various products generated in the oil tank 227 attached to and absorbed by the object to be treated. Further, since an earth electrode 228 opposed to the current-carrying electrode 226 is always required, one of the electrodes 226, 228, which are arranged substantially in parallel and opposed to each other, is a flyer electrode. it means that close the 2 0 opening 2 2 3, needs to be improved in terms of usability of the fryer one 2 2 0, flyers one _{2 2} 0 for bugs from such production site There was a problem that it was difficult to cope with the equipment configuration. In order to solve this problem, for example, the current-carrying electrode 222 and the ground electrode 228 are arranged facing the left and right wall surfaces of the flyer 220 without closing the opening 222 of the flyer 220. Even if it is touched, This results in a new problem that the heated state and the skin formation state are different between the surface and the surface on the ground electrode 228 side. Next, Fig. 17 is a conceptual diagram of a flyer 130 mounted on a conveyor device of Patent 34776776 (K'S'A) to which the above-described electric field treatment is applied. A pair of conveyors that move in the same direction at substantially the same speed and are arranged in a pair at the top and bottom in approximately parallel opposition to the inside of the oil tank of the flyer 230 and the end of the endless belt made of insulating material. Is fixed to the frame frame 237 with the support / drive unit 235, 236, made of insulating material, and the electrode plate 238 is placed in the loop space of the upper conveyor 232. The lower endless conveyor belt 233 made of conductive metal is used as a ground electrode and connected to the ground ground 239. The conveyor-mounted flyer with such a configuration has an upper endless belt 232 made of an insulating material and supports and drives 2 35, 2 3 6 made of an insulating material. However, there is a major defect in that the durability of oil and abrasion resistance is insufficient, the replacement cost of parts is excessive, and the practicality is poor. Disclosure of the invention

The present invention has been made in order to solve the above-mentioned problems, and a first object of the present invention is to form an electric field region with a more uniform electric field intensity than in the electric field processing according to the prior art, thereby achieving a high-efficiency electric field. An object of the present invention is to provide an electric field processing device capable of processing. The electric field treatment is performed in order to reform the fluid or to reform an object to be processed present in the fluid region and having a different dielectric constant. Here, the fluid includes a liquid such as water or oil, or a gas such as air, and generally refers to a fluid having a predetermined dielectric constant. In addition, reforming means, for example, increasing the molecular density of the liquid to be treated with an electric field, controlling the solubility, improving the permeability, generating a quasi-supercritical state, changing the phase transition temperature point (boiling point or melting temperature), Say etc. In addition The processed product refers to a solid, liquid, gas, gel, or colloidal substance containing water, and more specifically refers to, for example, a cooked product in a cooking liquid, a food in a refrigerator, and the like. A second object of the present invention is to form an electric field region with a potential of uniform intensity. An object of the present invention is to provide an electric field processing apparatus that is superior to the electric field processing according to the related art for forming an electric field of a uniform potential. A third object of the present invention is to provide an electric field processing apparatus capable of forming an electric field region with a uniform intensity and performing an electric field processing with a higher transmission efficiency for an object to be processed than the electric field processing according to the related art. A fourth object of the present invention is to provide an electric field processing apparatus capable of performing electric field processing by uniformly increasing the voltage of an object to be processed to be higher than that of an electrode with respect to a voltage difference between an electrode and an object to be processed, as compared with the electric field processing according to the related art It is to provide. A fifth object of the present invention is to make the fluid in the electric field treatment region or the objects to be treated having different dielectric constants existing in the fluid region into electrodes during the electric field treatment process, thereby achieving a higher electric field treatment than the conventional electric field treatment. An object of the present invention is to provide an electric field processing device capable of efficiently processing an electric field. In order to achieve the above object, according to the present invention, in an electric field generated by applying an alternating voltage to an electrode, constituent molecules inside the object to be processed are electrically polarized along the direction of the electric field lines of the electric field. While the polar constituent molecules are repeatedly and alternately aligned with the polarity reversal of the alternating voltage, the arrangement of the constituent molecules is gradually and regularly arranged to remove impurities and the like mixed between the constituent molecules. In an electric field treatment apparatus that positively supplies ions and simultaneously supplies an induced current to constituent molecules to impart various effects to the object to be processed and reforms the object, the alternating voltage applied to the electrode is changed to an object to be processed. Across The applied voltage is an alternating voltage of the same polarity, which is applied to a pair of plate electrodes arranged to face each other or a cylindrical electrode surrounding the object to be processed, and the object to be processed in the electric field is connected to the electrode. When the electrode is made to have the same polarity and the object to be processed is electroded to a positive potential, the positive polarity side of the polarized constituent molecules inside the object to be processed is infinitely far space where the polarity is relatively negative. When the object is turned into a negative potential by reversing the polarity of the applied alternating voltage, the negative polarity side of the polarized constituent molecules inside the object is relatively positive. An electric field process is performed by aligning and aligning the molecules toward an infinity space showing polarity, and performing alternating alignment and alignment of polarized constituent molecules inside the object to be processed by reversing the polarity of the applied alternating voltage. It discloses a processing apparatus. By sandwiching, enclosing, or enclosing with a bottomed shape the target electric field processing region and the target electric field processing region, the target electric field processing region and the electric field region formed by the plural electrode surfaces match. As a result, a uniform and intense electric field is formed in the target electric field processing region. Alternatively, use electrodes to sandwich, enclose, or enclose the area with the bottomed shape in the target electric field treatment area, and further use multiple electrodes to create multiple horizontal-tiered partitions and multiple vertical fence-shaped partitions A plurality of grid-like partitions, a plurality of cylinders, or polygonal pillars are arranged to form an electric field having a uniform intensity on a target electric field processing region. The shape of the surface where the electrode faces the object to be processed is a flat plate, a wavy shape, a needle shape, a concave shape, a convex shape, a plurality of protruding shapes, a plurality of concave shapes, a plurality of convex shapes, a plurality of perforated shapes. Yes, it can be selected according to the application for which the electric field treatment device is used. In the target electric field treatment area, an electrically non-contact layer is secured between the electrode and the object to be processed, and the electrode is hermetically shielded with an insulator. The main reason for this hermetic shielding is not only to completely insulate the electrodes from, for example, frying oil, but also, for example, if the electrodes are exposed to air, This is to prevent the electrodes from being slightly and sequentially discharged with respect to moisture in the air, thereby preventing the efficiency of the electric field treatment of the object to be treated from being lowered. Examples of the insulator include a base material formed of a non-woven fabric, a woven fabric, or a porous body of a fluororesin such as polytetrafluoroethylene, a glass fiber, a ceramic fiber or a cellulosic fiber, an engineering plastic, Alternatively, a composite with a resin made of super engineering plastic can be used. Alternatively, a composite of the above-described base material and a fluororesin may be used. Alternatively, a composite of the above base material and a resin comprising a polytetrafluoroethylene, a perfluoroalkylvinyl ether copolymer, or a tetrafluoroethylene-hexafluoropropylene copolymer may be mentioned. . The choice can be made according to what kind of electric field treatment device the electrode is used for. The electrodes include, in addition to metals, conductive polymers, such as polyacetylene, polyaniline, polysilane, and polybenzoimidazole, and composites of such conductive polymers and metals. By configuring the electric field treatment device as described above, since the alternating voltage of the same polarity is applied to a plurality of electrodes, a positive potential: electric lines of force from each given electrode to infinite space, Or, conversely, the lines of electric force from the infinity space to each electrode to which the negative potential is applied are weighted to the object to be processed, so that more lines of electric force pass through the object to be processed. become. For this reason, the object to be processed is placed in a strong electric field, and the object to be processed is at a higher potential than in the prior art. With the reversal of the applied alternating voltage, the processed object repeats the reversal from the positive high potential to the negative high potential, and further from the negative high potential to the positive high potential, and alternately aligns at the level of the polarized constituent molecules. The material to be processed is reformed while repeating. This means that, compared to the conventional technique that simply uses an alternating electric field generated between electrodes of different polarities, alternating orientation alignment at a high potential state is achieved, and the object to be processed can be efficiently modified. On the other hand, in the electric field treatment apparatus according to the prior art, for example, in the warehouse of Japanese Patent Application Laid-Open No. 2-2577867 (Otsuki) shown in FIG. The high-voltage is applied directly to the food, and the electric field is processed by the voltage difference between the food to which the high voltage is applied and the ground wall inside the door installed on the near side in the figure. In other words, alternating voltages of different polarities are applied to the ground wall and the conductive shelf (placed food). On the other hand, in the present invention, for example, when a food is introduced into the space between the two left and right electrodes to perform the electric field treatment, the left and right electrodes have alternating voltages of the same polarity as described above. Both electrodes are always supplied with a positive potential or a negative potential because they are applied. Therefore, even if the applied voltage is increased in order to perform the electric field treatment efficiently, no discharge action occurs between the two electrodes. This has the advantage that the applied voltage can be flexibly and sufficiently increased according to the characteristics of the object to be processed without fear of discharge between the electrodes. Further, in the present invention, the electrode pair to which the alternating voltage having the same polarity is applied is arranged in a fluid existing region functioning as a dielectric, and the processing target having a dielectric constant different from the dielectric constant of the fluid in the fluid. An object may be charged to reform the object. For example, an electrode pair for applying alternating voltage of the same polarity may be arranged in the frying oil, and the food put in the frying oil may be subjected to an electric field treatment. In this electric field treatment, a higher electric potential is applied than in the conventional technology, so that the heat conductivity to the food is improved as compared with the conventional technology, and a product with good oil drainage can be fried. Furthermore, in the present invention, a zero-potential electric field is applied at a position facing an object to be processed in the electric field by applying an alternating voltage of the same polarity to control the direction and gradient of the electric flux lines in the electric field. A control member may be provided. The electric field control member is an earth electrode, and the earth electrode is moved in a direction of approaching (separating and approaching) in the direction of the electric line of force or in a direction orthogonal to the line of electric force, thereby achieving the same effect as described above. Caused by the application of alternating polarity voltage The configuration may be such that the gradient and direction of the electric field lines in the electric field are changed. The ground electrode is made of a conductive material, for example, a conductive metal, and has a shape of a flat plate, a wire mesh, a lattice, a perforated plate, a needle, a wire, a protrusion, a sphere, and an insulating material. May be coated with a material. Furthermore, the present invention provides a method for increasing the molecular density of an object to be treated, controlling solubility, improving permeability, generating a quasi-supercritical state by the electric field treatment, and forming a phase transition temperature point (boiling point or It is also possible to modify the melting temperature) or to separate dissolved substances (purification of liquids such as sewage and blood). This is especially true in the present invention, since the alternating voltage of the same polarity is applied to a plurality of electrodes as described above, no discharge phenomenon occurs between the electrodes even when a high voltage is applied, and therefore, compared to the prior art. And electric field treatment in a wide range of fields. As a more specific configuration of the present invention, the electrode pair facing the alternating voltage of the same polarity may be formed of a fried oil, water, or the like which functions as a dielectric filled in the food heating processing region of the food heating processing cooking device. The food, which is the object to be treated, having a dielectric constant different from the dielectric constant of the medium, is placed in the heating processing medium, and the electric field treatment is performed by the electric field treatment during the heating processing of the food. May be modified. Similarly, an electrode pair facing the alternating voltage of the same polarity is disposed in a space area functioning as a dielectric in the food storage area of the food storage device, and a dielectric constant different from the dielectric constant of the space is provided in the space area. The food to be treated may be stored, and the food may be modified in the process of storing the food. BRIEF DESCRIPTION OF THE FIGURES

BEST MODE FOR CARRYING OUT THE INVENTION

 FIGS. 1A and 1B are configuration diagrams of an electric field processing apparatus 1 according to a first embodiment of the present invention. In the electric field treatment apparatus 1 according to the first embodiment, a substance to be treated (for example, food) 5 is placed in an electric field treatment chamber 3, and an alternating voltage having the same polarity is applied across the substance to be treated 5. The two electrode plates 7 A and 7 B facing each other in parallel are arranged in the electric field processing chamber 3. The two electrode plates 7A and 7B are configured so that a high-voltage weak current obtained by transforming the voltage from the power supply 9 by the transformer 11 flows through the two electrode plates 7A and 7B. More specifically, a commercial frequency AC voltage from the power supply 9 is applied to the input side (primary side) of the transformer 11 and the output side (secondary side) of the transformer 11

The first conductor 13 is connected to the first pole 13 of the one pole 13 and the second pole 15, and the second conductor 19 is connected to the second pole 15. I have. Further, the first conductor 17 is connected to the ground 21. The second conducting wire 19 is connected to the branching device 23, and is branched into the second conducting wires 19A and 19B by the branching device 23 so that the electrodes are synchronized. The branched second conductive wire 19 A is connected to an electrode plate 7 A, and the second conductive wire 19 B is connected to an electrode plate 7 B, and these two electrode plates 7 A and 7 B are connected to each other. In the facing space, an electric field (in this case, a positive electric field 27) is formed. In the electric field processing apparatus 1 configured as described above, since the AC voltage of the commercial frequency is applied from the power supply 9, the alternating voltage of the constant frequency is always applied from the second conductor 19 to the branching device 23. Have been. For example, in the case of FIG. 1 (A), the case where the second conductor 19 is at a positive potential is shown, and two electrodes are passed through the conductors 19A and 19B branched from the branching device 23. Board 7 A, 7 B Since a positive potential is applied to both, the electric field region 27 between the electrode plates 7A and 7B is in a substantially equal potential state having a positive potential at any position. For example, it is assumed that the electric field region 27 is filled with frying oil, and a frying species or the like having a different dielectric constant from the frying oil is present as the processing object 5 in the electric field region 27. In this case, when a positive potential is applied to the electrode plates 7A and 7B, a positive electric field 27 is generated as the electric field because both electrode plates are of the same polarity. Therefore, the object 5 in the positive electric field 27 is also converted into an electrode, that is, a positive electric field is formed at any position in the water in the object 5. Since the space at infinity has a relatively negative potential with respect to the positive electric field 27, the polarized water molecules in the treatment object 5 are as shown in Fig. 1 (A). Then, the brass polarization side is attracted to the space at infinity where the potential becomes relatively negative, so that the alignment becomes aligned. In addition, since the electric field is fluctuated by alternating current, the potentials of the electrode plates 7 A and 7 B are constantly inverted repeatedly, and the electric field is also inverted to the plus electric field 27 or the minus electric field 28 accordingly. Therefore, the object to be treated itself is in a state where the electric charges are exchanged while constantly receiving the induced current in the electric field ₍ more specifically, in the case of FIG. 1 (A), the electrode plates 7A and 7A). Since a positive potential is applied to both B, a positive electric field 27 is formed between the electrodes at any location, and a positive electric field 27 is thus formed. The polar side is oriented and aligned so that it is drawn in the vertical direction in the figure, which is a space at infinity where the potential is relatively negative. Similarly, in the case of Fig. 1 (B), (A) is Conversely, since a negative potential is applied to both of the electrode plates 7 A and 7 B, a negative electric field is generated between the electrodes at any location, and a negative electric field 28 is formed. Molecules and classes The negative pole side is oriented and aligned so that it is drawn in the vertical direction, which is a space at infinity where the potential is relatively positive. In other words, the object to be treated is applied to the electrode plates 7A and 7B with the same polarity. When the alternating voltage is applied, it has a predetermined potential, so that On the other hand, it means a so-called floating electrode. The object to be processed, which constitutes the floating electrode, becomes an electrode body in an infinite space in a plus electric field and a minus electric field with the reversal of the polarity of the electrode plate. FIG. 2 shows experimental data obtained by measuring an electric potential in the internal space of the electric field processing chamber 3 formed between the above-mentioned electrodes. First, (A) shows a case where the alternating voltage of the same polarity according to the present invention is applied between two electrodes. The alternating voltage of 240 V from the transformer 11 via the branching device 23 is shown. Is applied. The electrodes 7A and 7B each have a potential of 240 V, and the potentials between them are measured at 1867 V, 144 IV, and 1869 V, respectively. These potentials naturally depend on the dielectric constant of the material between the electrodes (air in this data). When 240 V is applied to the electrode 7A, the space potential near the electrode becomes a potential curve A, and when 240 V is applied to the electrode 7B, the space potential near the electrode is a potential curve. B. Therefore, it is considered that a composite curve of these potential curves A and B becomes an output potential curve C. On the other hand, (B) is a case where the alternating voltage of the different polarity according to the conventional example is applied to the electrode 7 and the ground plate. Similarly, an alternating voltage of 240 V is applied to the electrode 7. In this case, the space potentials near the electrodes were measured at 919 V, 463 V, and 195 V, respectively. In other words, a sharp potential drop occurs from the electrode 7 toward the ground electrode having zero potential. When 240 V is applied to the electrode 7 A, the space potential near the electrode becomes a potential curve D. Fig. 3 shows that an insulating shelf is provided in the internal space of the electric field treatment room 3 formed between the electrodes, and the tap water as an object to be treated placed in an insulating container is placed on the shelf. It is the experimental data which measured the electric potential. First, (A) shows a case in which the alternating voltage of the same polarity according to the present invention is applied between two electrodes. Potential is about 3 A high potential of about 400 V from 400 V is measured. On the other hand, (B) is a case in which the same object is measured with the configuration according to the conventional technology. Here, the potential of tap water is also approximately 300 V from approximately 300 V as in FIG. 2 (B). An abrupt potential drop of 600 V was measured. In the electric field treatment, which is the subject of the present invention, as described above, the constituent molecules of the object to be processed are polarized by application of a high voltage, and the polarized constituent molecules are alternately aligned and aligned by an excitation vibration phenomenon. The object to be treated is reformed by regularly aligning it. Therefore, high voltage application is required for electric field treatment. However, in practice, there is a limit of applied voltage which is inevitable to occur between electrodes. Even when a high voltage is applied, if the space potential into which the object is charged is non-uniform, a problem occurs that the electric field treatment effect of the object is non-uniform. In this regard, in the electric field treatment apparatus according to the present invention, in which an alternating voltage having the same polarity is applied, an alternating voltage having the same potential and the same polarity is applied to a plurality of electrodes. ing. For this reason, it is possible to apply a high-potential alternating voltage to the object to be processed as compared with the conventional technology. And the alternating voltage applied in this high potential, for the constituent molecules of the object, also _c efficient electric field treatment to cause a strong excitation vibration phenomena is possible as further apparent from the above experimental data, The potential difference in the electric field processing space is small compared to the conventional technology. For this reason, it is possible to uniformly treat the object to be treated with an electric field.For example, if the object to be treated is a food, the electric field can be treated not only on the surface of the food but also inside the food. It has the advantage that the processing quality of the processing can be greatly improved. In this way, unlike the prior art in which only the vicinity of the surface of the object to be processed is electrodeized, the present invention maintains a high spatial potential between a plurality of electrodes, Because of the small difference between the polarities, all the molecules and cluster molecules in the object to be processed repeat the alternating alignment while reversing the polarized polarity simultaneously with the reversal of the potential of the same polarity electrode. By repeating such alignment, the molecules of the object to be treated and the cluster molecules undergo dielectrophoresis, and gradually become regularly arranged from the state of being irregularly arranged until then. In this case, a large cluster is divided into small clusters, and as this division operation progresses, it is gradually divided into molecular levels, and undergoes inversion dielectrophoresis with the reversal of the polarity of the electrode plate. In this case, since the same potential is induced in all the portions of the object to be processed, the orientation and alignment are performed uniformly and efficiently. Since the electric field treatment is performed in an electric field having a different polarity with respect to the nearby earth electrode and a non-uniform space potential, the above-described orientation by dielectrophoresis is mainly performed only on the surface of the object to be treated. It differs greatly from the present invention in that alignment is performed. In addition, the impurities extruded by the orientational alignment from the material to be processed move in the direction of the electric force between the electrode plates 7A and 7B, and can be removed from the vertical direction in the figure. Also, even if the distance between the electrode plates 7A and 7B is long, the lines of electric force fly toward the object 5 as long as the object 5 is present in the electric field. There is no need to adjust the distance between plates 7A and 7B. In addition, since the electron current is higher than in conventional electric field treatment equipment, bacteria cannot survive in the presence of a large amount of electrons, thus improving the bactericidal effect. FIGS. 4 (A) and (B) are configuration diagrams of an electric field processing apparatus 2 according to a second embodiment of the present invention. The electric field processing apparatus 2 according to the first embodiment has the same configuration as that of FIG. 1 except that the object 5 is charged into the electric field processing chamber 3. Electrode plate 7C is placed for the electric field processing chamber 3. This is different from the first embodiment in that The cylindrical electrode plate 7C is configured such that an alternating voltage is transformed from a commercial power supply 9 by a transformer 11 so that a high voltage weak current flows. Note that the cylindrical electrode plate 7C is not limited to a circular shape, but is a curved body having at least opposing surfaces, that is, an opening cylinder or a tubular body having a cross section of a perfect circle, an ellipse, an ellipse, or the like, a substantially U-shaped cross section or a bottomed cylinder. It may be composed of a tank, or a polygonal prism, polygon tube or polygon tank having a triangle or more having opposing surfaces. That is, any structure may be used as long as it is electrically open to the infinity space and the lines of electric force from the electrodes can exit toward the infinity space having this zero potential. The electric field treatment apparatus according to the second embodiment is configured such that a high-voltage weak current flows from the transformer 11 to one end of the electrode plate 7C as in the first embodiment. Also in this case, the electric field region in the cylinder has positive and negative electric fields alternately formed according to the alternating voltage as in the first embodiment, and as shown in FIGS. The polarity of one of the clusters is inverted, and the modification process is performed while aligning the alignment by dielectrophoresis. That is, in the case of FIG. 4 (A), a positive electric field is formed by applying a positive potential to the cylindrical electrode plate 7C, and the positive electrode of the molecules and cluster molecules in the polarized object to be processed is formed. The side is drawn along the line of electric force to the space at infinity, which is at a relatively negative potential, and is aligned and aligned at the molecular level. Similarly, in the case of FIG. 4 (B), a negative electric field is formed by applying a negative potential to the electrode plate 7C, and the negative electrode of the molecules and cluster molecules in the polarized object to be processed is formed. The sides are aligned so that they are drawn along the direction of the electric field line into infinity space at a relatively positive potential. In this way, unlike the prior art in which only the vicinity of the surface of the object is converted to an electrode, in the present invention, the electrodes of the same polarity are maintained at substantially the same potential, so that all the molecules and clusters in the object are treated. The molecules are repetitively oriented and aligned while reversing the polarized polarity of the molecules in accordance with the reversal of the potential of the counter electrode. FIGS. 5 (A) and (B) are configuration diagrams of an electric field processing apparatus according to a third embodiment of the present invention, wherein a ground structure (electric field control member) 31 A, 31 B are located outside the electric field 27 so that the two electrodes face each other in a direction orthogonal to the facing direction of the two electrode plates 7 A and 7 B of the first embodiment. It is arranged. In the case of the second embodiment, it may be disposed outside the electric field 27 in the space above the upper opening of the cylindrical electrode plate 7C. The ground structures (electric field control members) 31 A and 3 IB are provided so as to be movable up and down and left and right. In FIG. 5 (A), the grounding structure is located almost at the center between the electrodes, and in FIG. 5 (B), it is slid to a position relatively close to the right electrode (7B). Each is illustrated. These two ground structures 31 A and 3 IB are connected to a ground ground wire 33. Further, the 'earth structures 31A and 31B' are configured such that, for example, an earth material is covered with a mesh-like earth storage body made of an insulating material. The base material is made of, for example, a conductive metal as a conductive substance, and has a shape such as a wire mesh, a lattice, or a plate with holes, which does not hinder the circulation of cool air. The ground container is not limited to the insulating material as described above, and may be made of an insulated material. Further, the shape of the ground container is a net shape such that the workpiece 5 does not directly contact the ground material. Therefore, since the grounding structures 31A and 31B are covered by the insulating grounding container, the workpiece 5 is not directly contacted with the grounding structures 31A and 31B and is even. Will be affected by electricity. In this case, the electric lines of force 35 generated from the electrode plates 7A and 7B arranged to be substantially parallel to each other are located outside the electric field 27, and are opposed to the electrode plates 7A and 7B. Are arranged so as to face each other in a direction perpendicular to the To the ground structures 31 A and 31 B as the electric field control members. More specifically, the provision of the earth structures 31A and 31B causes the direction of the electric field generated between the electrode plates 7A and 7B. And the degree of inclination can be finely adjusted. In other words, the electric field generated between the electrode plates 7A and 7B flies so as to be attracted to the plus and minus charges of the moisture of the object 5 in the electric field region 27, and the ground structure is formed by the object 5 itself. It is possible to change the direction of the electric field lines in the electric field by turning in the direction of the objects 31A and 31B, and to move the space potential in the electric field 27 by moving it in the perspective direction. Fine adjustment is possible. As described above, by configuring the ground structures 31A and 31B as electric field control members in this way, by adjusting the relative position with respect to the electric field region 27, the electrode plates 7A and 7B are formed. The direction and intensity of the electric field generated between the electrodes can be adjusted, and as a result, the electric field around the object to be processed can be adjusted. In other words, by changing the arrangement of the electrode plates 7A, 7B and 7C and the grounding structures 31A and 31B, it is possible to use the electronic current effect according to food characteristics, food heating and cooking purpose. Become. FIG. 6 shows an application example 1 in which the electric field treatment device described in the third embodiment is built in a cylindrical material treatment device. (A) is a side sectional view.

(B) is a top sectional view.

On the provided insulating peripheral wall 52, an electrode 54 hermetically shielded with an insulator is mounted. The electrode 54 is 7 C in FIG. 4, and the region constituted by the electrode 54 is the electric field treatment region 55.

(Electric field processing room 3 in Fig. 4). The electrode 54 is connected to the transformer 2 (2 in FIG. 4) by a withstand voltage high voltage line 19 (19 in FIG. 4). The lower part of the electric field treatment area 55 is located on the upper surface of the detachable bottom 53, and the electrode 54 and the insulating layer 56 A workpiece mounting table 57 made of an insulating material is disposed, and the workpiece (5 in FIG. 4) is mounted on the workpiece mounting table 57 and the apparatus is used. Use the electrode 54 with a non-contact layer secured. Remove the detachable bottom 53 of this device, place 600 cc of tap water at 21 ° C in the electric field treatment area 55 in a glass beaker, pass the same polarity alternating voltage to the electrode 54, and boil. As a result of the test, the time to reach 96 ° C was 409 seconds, and it was 555 seconds under the condition of no application. FIGS. 7 and 8 show an application example 2 in which the electric field processing apparatus shown in FIG. 5 is incorporated in a food heating processing apparatus. In the food heating / cooking apparatus 60 of this application example 2, the outer wall 61 of the exterior part 61 made of a conductive metal or the like is insulated, and the left and right inner walls 62 of the inner wall 62 are insulated. The electrodes 65, 65 (corresponding to 7A and 7B in FIG. 5) which are hermetically shielded by an insulator are arranged substantially parallel to each other. Above the peripheral wall of the inner wall 62, there is provided an opening 63 for charging the food F to be processed, and a plurality of insulated heating tubes 6 4 are provided below the peripheral wall of the inner wall 62. One of the heating tubes 64 is connected to a heating device installed outside the food heating / processing and cooking device 60, and the other is connected to a smoke exhaust system. The region formed by the inner wall surface 62 and the plurality of heating tubes 64 is an electric field treatment region 66, which is 27 in FIG. Oil is injected into the electric field processing area 66, heated by the plurality of heating tubes 64, and the food F to be processed (this is 5 in FIG. 5) is injected through the opening 63. . A non-insulated bottom 65 exists below the heating tube 64, and replaces 31B in FIG. 5 through the food cooking apparatus 60. 3 is 3). The electrodes 7A and 7B are connected at 19A and 19B in FIG. 5, respectively. In this embodiment, the apparatus is arranged with the ground on the lower side. When the electrodes face each other in the front-rear relationship, the ground may be arranged in the left-right relationship or the ground may not be provided. In this embodiment, the electrodes 65, 65 are arranged in a left-right relationship, but they may be arranged on three or four surfaces of the peripheral wall. If it is not possible to attach the grounding earth 21 shown in Fig. 5 at the place where the food heating / processing equipment 60 is used, a resistor 17A is interposed in the first conductor 17 in Fig. 5 Alternatively, the tip may be connected to the second conductor 19. The potato fried was made to reach an oil temperature of 180 ° C and a core temperature of 90 ° C using an alternating voltage of 100mA.6KV, and the oil absorption was analyzed and calibrated. 100 g, which was 4.6Z 100 g in the conventional electric field treatment device in which the current-carrying electrode and the ground electrode were arranged substantially parallel to each other. This is due to the effect of concentrating the peripheral heat around the potatoes and the improvement of the heat transfer to the core by converting the potato itself into an electrode, which shortens the frying time, resulting in a reduction in the amount of heat exchange compared to the conventional technology. Controlling the absorption of oil in fried products will greatly contribute to maintaining and improving health by controlling the oil intake of those who eat them. 9 and 10 show an application example 3 in which the electric field treatment device shown in FIG. 5 is incorporated in a food heating / processing device. In the heating and cooking apparatus 70, the entire inner wall surface 72 of the exterior part 71 formed of a conductive metal or the like is insulated except for the bottom part 73. An endless conveyor belt 75, 76 made of a conductive metal is provided in a region 74 formed by the inner wall surface 72 and the bottom portion 73, and the conveyor belts 75, 76 are disposed in front and behind the region 7. An opening is provided and fixed to the left and right frame plates of the frame body 79 on which insulating frame plates 77, 78 are attached to the left and right, and the conveyor belts 75, 76 mutually move at the same speed in the same direction. To drive while maintaining approximately the same interval 80 The drive shaft is connected to a drive device external to the heating and cooking device 70 by a chain belt or the like and driven. At the interval 80 between the conveyor belts 75, 76, the left and right frame plates 77, 78 are air-tightly shielded with electrodes, and the electrodes 7A, 7B in FIG. The conveyor belts 75 and 76 are 31A and 31B in FIG. 5, and the area formed by the electrodes 7A and 7B facing each other at the interval 80 is an electric field processing section, that is, a fifth section. This is 27 in the figure. Oil from an external heat exchanger is injected into the area 7 formed by the inner wall 7 2 and the bottom 7 3, and the workpiece (5 in FIG. In this configuration, the conveyor belts 75, 76 pass through the frame plate 77, 78, via the frame body 79, and the heating and cooking device 70 To earth ground 8 3 (33 in FIG. 5). The electrodes 7A and 78 are connected at 198 and 19B in FIG. 5, respectively. If it is not possible to attach the grounding earth 21 shown in Fig. 5 at the place where the food heating / processing equipment 70 is used, a resistor 17A is interposed in the first conductor 17 in Fig. 5 Alternatively, the tip may be connected to the second conductor 19. FIGS. 11 and 12 show an application example 4 in which the electric field treatment device shown in FIG. 5 is incorporated in a food heating and cooking device. In the food storage device 100, heat insulating material 102 is placed inside the exterior part 101 made of conductive metal, etc., on the left, right, back and door walls, and is insulated on the surface of the heat insulating material 102. Materials 103 are mounted on the left, right, back and door walls. On the surface of the left and right wall surfaces 104, 105 on which the insulating material 103 is mounted, electrodes 7A, 7 which are hermetically shielded with an insulator are provided on the left and right sides in substantially parallel opposition. A frame 106 made of an insulating material is arranged at a position avoiding 7B, and the frame 106 has electrodes 7A, 7B and a ground structure 107 (in Fig. 5, 31A, 3A). IB) and a non-contact layer are secured and a shelf 107 is attached. Ground structures 107 are arranged above and below the region formed by the electrodes 7A and 7B facing each other. Upper and lower ground structures 1 0 An area 108 formed by the electrode 7 and the electrodes 7A and 7B facing each other is an electric field processing area (27 in FIG. 5). The object to be processed (5 in FIG. 5) is placed on a shelf 107 in the electric field processing area 108. The electrodes 7A and 7B are connected to 19A and 19B in Fig. 5, and the upper and lower ground structures 107 are grounded via the food storage device 100 (3 in Fig. 5). 3) Connect to. The back wall 110 has a structure in which a supply / discharge port connected to an external heat exchanger is provided. In this application example, the electrodes are installed on both the left and right walls. However, the electrodes may be installed on the left and right walls and the inner wall of the door, or on the left and right walls and the inner wall of the door. Further, the earth structure 107 may be either one of the upper and lower surfaces instead of the upper and lower surfaces, or may be unmounted. If it is not possible to attach the grounding earth 21 shown in Fig. 5 at the place where the food storage device 100 is used, connect a resistor 17A to the first conductor 17 in Fig. 5 The tip may be connected to the second conductor 19. For example, when storing 140,000.Z g of viable primary bacteria of water-washed lettuce at a storage temperature of 4 ° C to 6 ° C, use an alternating voltage of the same polarity of 100mA.10KV. Comparing the change in the initial count of general viable bacteria in the food storage device of the present invention and the conventional parallel type of the current-carrying electrode and the earth electrode, the general viable count after 48 hours is the same as that of the food of the present invention. The storage device was 38,000.Zg, and the conventional one was 120,000.Zg. This is due to the ozonation effect around the lettuce due to the uniform electric field formation.

It is considered that the oxidative alteration was controlled through the negative ionization of oxygen molecules inside the lettuce due to the weak current permeation caused by the surface bacteriostat and the lettuce itself as electrodes, and the growth of microorganisms was suppressed.

Therefore, it can contribute to the protection of natural resources through the control of the period of preservation stability, the protection of food resources, the allocation of food resources, and the control of the amount of waste. Industrial applicability

While the electric field treatment device according to the related art applies an alternating voltage of a different polarity to the electrodes, the present invention applies the same alternating voltage to the electrodes, so that the following effects can be obtained. For example, the reforming of commercially available purified water into electronic water is performed by enclosing + 4 ° C purified water in a glass specific gravity bottle, which is an insulating container, in an environment of + 4 ° C. When an alternating voltage of 100 mA.10 KV. Is applied for 30 minutes using an electric field treatment device that applies an alternating voltage of the same polarity, the specific gravity is reduced by 0.074% and the volume is reduced by 0.15%. Since water is assumed to contain a small amount of gas even though it is water, it is expected that these will evaporate and disappear in the reforming process.However, the electric field treatment device according to the present invention for applying an alternating voltage of the same polarity is provided by water. It can be confirmed that it exerts the effect of controlling. Similarly, as an effect of water control of the electric field treatment apparatus for applying the alternating voltage of the same polarity according to the present invention, for example, applying the alternating voltage of the same polarity to the raw tuna having 38,000. When the alternating voltage lOOmA.OKV. Was continuously applied for 48 hours at + 4 ° C to +5 using an electric field treatment device, the general viable cell count was 5,100.Zg. This is because the characteristic of the electric field treatment device according to the present invention, which applies an alternating voltage of the same polarity, changes the interaction of water molecules into hydrogen bonds due to the formation of a capacitating sunset (relaxing or breaking = water molecules). As a result, the water content of the tuna is modified, resulting in highly permeable bioactive water, and the oxygen is modified into negative ions, inhibiting the growth of microorganisms and reducing it. It is understood that oxidative deterioration was suppressed because of the action. The electric field treatment apparatus according to the present invention does not directly energize the shelf plate as compared with Japanese Patent Application Laid-Open No. 2-2577867 (Otsuki), and the shelf plate is installed so as to be electrically insulated from the electrodes and the ground. And a more uniform space between the electrodes compared to conventional electric field treatment equipment. An electric field treatment region having a potential can be formed. Since the shelf is electrically insulated, the shelf can be made of either conductive metal or insulating material.In addition, no contact resistance occurs even if the workpiece is placed directly on the shelf, No Joule heat is generated due to contact resistance. Further, since the potential applied to the object to be processed can be raised more than the potential of the electrode surface, a large amount of the object to be processed can be uniformly treated with an energy-saving electric field in a short time. In addition, since the object to be processed is not placed in direct contact with the conductive shelf plate, the transmission performance is excellent and a uniform electric field can be formed, so that the molecules of the object to be processed are perfectly aligned and aligned at the molecular level. In addition, a uniform electric field treatment can be performed regardless of the object to which the insulating material is attached or not. Taking the phase transition temperature of water as an example, refrigeration temperatures of -4 ° C to -5 ° C without wrapping six workpieces containing 500 cc of tap water at a water temperature of 19.8 ° C in a resin container If the voltage is maintained and the alternating voltage of 100 mA.6 KV is continuously applied, the electric field treatment apparatus of the present invention for applying the alternating voltage having the same polarity does not freeze at all, but the conventional method in which the electrode and the ground plate are substantially parallel to each other is 2. In the conventional method, in which the object is placed on the electrode and the surroundings are insulated, the whole is frozen in three hours. This proves that the water was reformed by the electric field treatment and the water became hard to freeze, but it can be said that there is a clear difference in terms of the efficiency of the electric field treatment. Taking the heat concentration effect as an example, 15 commercially available frozen croquettes with a product temperature of 20 ° C are put into the entire opening of the fryer at an oil temperature of 180 ° C, and the core temperature reaches 90 ° C. When an alternating voltage of 100 mA.6 KV is applied to determine the deep color, the electric field treatment device of the present invention that applies an alternating voltage of the same polarity does not cause any irregularities in the deep color even if the return operation is omitted, With the conventional flyer with the electrodes and the earth plate facing almost in parallel, if the turning operation was omitted, the lower surface side of the input product generated eight items that did not have a deep-colored color, and even after the turning operation, five occurred. This is because the electric field treatment apparatus of the present invention for applying an alternating voltage of the same polarity forms an electric field having a uniform intensity, so that environmental heat can be efficiently and uniformly concentrated on an object to be treated. In the conventional method, it is considered that environmental heat cannot be uniformly concentrated on the object to be treated because an electric field having a uniform intensity cannot be formed. Further, for example, when adjusting the frying speed of fried food, it is possible to add 10 commercially available freezer packs at 125 ° C to 180 ° C frying oil using an alternating voltage of 100mA.6KV. Comparing the time required to reach the eclipse temperature of 90 ° C., the electric field processing apparatus of the present invention took 180 seconds, and the conventional electric field processing apparatus in which the current-carrying electrode and the ground electrode were arranged substantially parallel to each other took 300 seconds. According to the electric field treatment device of the present invention, the object to be treated in the electric field treatment region is converted into an electrode body having the same polarity as the electrode, and the object to be treated becomes a so-called floating electrode, and the electric field is emitted toward the earth. . Therefore, in addition to the concentration of ambient heat on the workpiece, the heat transfer, which is inserted into the core, is added to the weight, which reduces the fly time and greatly contributes to improving productivity.
