Description

  The present invention relates to a method for maintaining freshness at room temperature using a DC electrostatic field.

  Conventionally, refrigerators and freezers are used to maintain freshness at low temperatures. Further, in order to improve the maintenance of freshness, an object is placed in an electrostatic field space.

  By the way, in recent years, the preservation range has been widened and attention has been paid to a method for maintaining freshness at room temperature (generally 0 ° C. to 40 ° C.). Placed in an electrostatic field space, the freshness, long-term storage, and surface sterilization are possible by the redox action of the electrostatic field.

  However, at room temperature, there is a problem that reproducibility of maintaining freshness is poor only by using an electrostatic field.

  This invention is made | formed in view of such a point, The objective is to provide the freshness maintenance method in the normal temperature using a direct current | flow electrostatic field.

  In order to solve the above-described problems, the present invention relates to a method for maintaining freshness using an electrostatic field. The object is reduced electrostatically charged with a minus high voltage generation module, and the object space is added with a plus high voltage generation module. Or the ozone generation module releases ozone into the target space.

  According to the freshness maintaining method according to the present invention, reproducibility of maintaining freshness was poor with only the reduced electrostatic field, but reproducibility is enhanced by placing the object space in an oxidizing electrostatic field or an ozone environment. In addition, by using a direct current electrostatic field, it is possible to reduce the size of the apparatus as compared with the case of alternating current using an alternating current transformer or the like.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram for explaining a freshness maintaining method by reduction electrostatic charging and spatial discharge of oxidized electrostatic.

  In FIG. 1A, a negative high voltage generation module 1, a positive high voltage generation module 2, and an insulating pallet 4 are provided. Moreover, in FIG.1 (b), the minus high voltage generation module 1, the plus high voltage generation module 2, and the insulated pallet 4 'which only has an electrically conductive plate on the upper surface are provided.

  In the negative high voltage generation module 1, the negative charging output portion 1a is brought into contact with an object (FIG. 1 (a)), or the negative charging output portion 1a is brought into contact with a conductive plate of an insulating pallet ( In FIG. 1 (b)), the object is charged on the output side (-), thereby reducing and charging the object. Also, contact neutralization of + -potential is performed. This contributes to surface sterilization of the object.

  The plus high voltage generation module 2 contributes to space sterilization by discharging into the space on the object space side (+) by the plus discharge output unit 2a. Moreover, since a very small amount of ozone is generated with the positive discharge, it contributes to space sterilization with ozone.

  In FIG. 2A, a negative high voltage generation module 1, an ozone generation module 3, and an insulating pallet 4 are provided. Moreover, in FIG.2 (b), the minus high voltage generation | occurrence | production module 1, the ozone generation module 3, and the insulated pallet 4 'which only has an electrically conductive plate on the upper surface are provided.

  The negative high voltage generation module 1 has its negative charge output portion 1a in contact with an object (FIG. 2 (a)), or the negative charge output portion 1a is in contact with the conductive plate of the insulating pallet 4 ′. (FIG. 2 (b)), the target is charged by reduction by charging the target at the output side (−). Further, the catalytic decomposition of −potential and ozone is caused. This contributes to surface sterilization of the object.

  The ozone generation module 3 contributes to space sterilization by releasing ozone to the object space side (trace ozone space) at the ozone output unit 3a.

  In addition, the present invention is based on local harvest warehouses by applying freshness maintenance methods to containers, etc., as well as freshness and processed products such as food fields and fresh flowers, keeping freshness in distribution, long-term storage, and surface sterilization. It is possible to maintain freshness and thaw frozen products on the warehouse base and the transport base.

  The freshness keeping method according to the present invention is useful as a method for improving the reproducibility of freshness keeping at room temperature.
