Description
Technical field
The present invention relates to the fresh-keeping instrument of a kind of fruits and vegetables process, belong to field of human life.
Background technology
At present, the preserving fruit and vegetable utilizing process many employings deepfreeze on market, controlled atmosphere storage, ionising radiation preservation and freshness, fresh chemically, heat treatment, the methods such as natural biological is fresh-keeping.Wherein controlled atmosphere method and refrigeration need to configure the large preservation of corresponding equipment investment costly; Chemical treatment method can make residual corresponding noxious material in fruits and vegetables; Irradiation storage preservation technique and natural biological preservation method concrete operations difficulty, economic feasibility is low; Various method all respectively has quality.
Summary of the invention
The object of the present invention is to provide a kind of a kind of fruits and vegetables process fresh-keeping device that can extend the preserving fruit and vegetable utilizing phase.
Technical solution
The present invention includes: the first coil, the second coil, distance between first coil and the second coil equals the radius of the first coil or the second coil, and the first coil is with the second coils connected in series and be connected by the power supply of wire with external adjustable output voltage or output current adjustable.
